 # Notarius
 
-Notarius is a Go CLI for extracting structured artifacts from source material
-with explicit, configurable pipeline modules.
+Notarius is a Go CLI for turning source material into structured artifacts with
+configured extraction pipelines. The implemented D&D workflow reads Seriatim
+transcript JSON and can produce scene descriptions, item and currency events,
+NPC identities, combat turns, NPC interactions, and spell casts.
 
-The current implementation reads Seriatim transcript JSON, chunks the source
-units, extracts D&D spell-cast artifacts with a Scriptorium-backed LLM runtime,
-and writes JSON output. Add `--debug` when a per-run inspection bundle is
-needed.
+## Quickstart
 
-```sh
-OPENROUTER_API_KEY=... \
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
+Provide an OpenRouter API key through the environment, then run the maintained
+minimal example:
+
+~~~
+OPENROUTER_API_KEY=your-api-key \
+  go run ./cmd/notarius run dnd-session \
+    --config examples/dnd-minimal.config.yml \
     --input examples/seriatim-minimal-transcript.json
-```
+~~~
 
-This invocation uses the maintained example configuration and input. See the
-configuration and operations references for profile selection, credentials, and
-run artifacts.
+The command publishes a JSON output bundle. Its command syntax and exit
+behavior are documented in the [CLI reference](docs/cli.md); configuration,
+credentials, and module selection are owned by the
+[configuration reference](docs/config.md).
 
-Useful references:
+For the complete ordered D&D workflow, use
+[the complete configuration](examples/dnd-complete.config.yml) with
+[its synthetic transcript](examples/dnd-complete-transcript.json). It
+demonstrates all implemented D&D lanes and the supporting campaign references.

+# ADR-0009: Prefer minimal evidence-grounded extraction artifacts
+
+**Status:** Accepted
+**Date:** 2026-07-22
+
+## Context
+
+Notarius is intended to extract structured facts from source material. Several
+early D&D artifacts grew to include descriptive prose, inferred relationships,
+immediate outcomes, summaries, and other enrichment alongside the facts that
+identify an event or entity. Those fields make one model call responsible for
+both extraction and synthesis.
+
+In practice, the richer contracts have produced overlapping or weakly grounded
+fields and have made structurally valid, semantically coherent output harder for
+cost-effective smaller models. They also increase prompt size, validation and
+normalization policy, durable schema surface, downstream coupling, and the
+number of claims whose provenance must be evaluated.
+
+The application needs a consistent rule for deciding what belongs in an
+extractor before redesigning the current D&D spell, NPC, and combat-turn
+contracts or adding new artifact families.
+
+## Decision
+
+An extraction module answers one narrowly stated question and returns the
+smallest durable structured artifact that usefully answers it.
+
+Every model-produced field in an extraction artifact must:
+
+- be necessary to answer the extractor's stated question or serve a known
+  downstream consumer;
+- represent a fact or bounded classification that can be supported directly by
+  cited source ranges;
+- remain independently meaningful without model-generated explanatory prose;
+  and
+- justify the additional prompt, schema, validation, normalization, and
+  compatibility surface it creates.
+
+Source references are required provenance for extracted records. Auxiliary
+references may disambiguate identities or canonical names, but they do not
+establish source facts and are not copied into evidence.
+
+Extraction artifacts do not include narrative summaries, general analysis,
+speculative enrichment, inferred biography or relationships, or redundant
+free-text descriptions by default. When such output has a demonstrated use, it
+belongs in an explicitly named extraction, classification, enrichment, or
+analysis module with its own contract and evidence policy.
+
+Occurrence-level facts are not forced into entity-level attributes. A fact
+that can change between encounters, such as an NPC's role in a scene, belongs
+on an occurrence artifact rather than as one scalar property of a normalized
+NPC registry entry.
+
+Deterministic mapping and normalization may assign application-owned
+identifiers, canonicalize known catalog values, order and deduplicate evidence,
+and collapse records under an explicit identity rule. They must not manufacture
+removed descriptive fields or synthesize missing claims to satisfy an older
+contract.
+
+This is a default design rule, not a prohibition on rich artifacts. A richer
+field is appropriate when its consumer, evidence semantics, and ownership are
+explicit.
+
+## Alternatives considered
+
+- Keep rich schemas and improve prompts or use larger models. This retains
+  potentially convenient prose but does not resolve overlapping field
+  responsibilities, weak provenance, higher cost, or unnecessary downstream
+  coupling.
+- Make enrichment fields optional. This reduces rejection pressure but leaves
+  ambiguous artifact semantics and inconsistent records, and many strict
+  structured-output providers still require nullable placeholders.
+- Keep minimal private LLM schemas while preserving rich durable artifacts.
+  Deterministic code would have to invent, default, or separately derive the
+  missing fields, hiding synthesis behind the extraction boundary.
+- Use one broad session-analysis module. This reduces the number of lanes but
+  couples unrelated facts, schemas, retries, evaluation, and downstream
+  consumers into one model call.
+
+## Consequences
+
+Extraction prompts and response schemas become smaller, more focused, and more
+suitable for lower-cost models. Artifacts carry fewer unsupported claims, and
+their evidence and validation policies become easier to explain and evaluate.
+Independent extractors can evolve, retry, and be consumed without requiring
+unrelated enrichment.
+
+Some descriptive convenience fields will disappear from primary artifacts.
+Consumers that genuinely need them may require a separate module and explicit
+pipeline step. Entity registries may no longer resolve aliases or relationships
+unless a dedicated, evidence-grounded capability supplies them.
+
+Removing durable fields is a schema compatibility change. Each affected
+artifact requires an explicit version and reference policy; private prompt
+changes alone are insufficient. Current-behavior integration and internal
+documentation must change with implementation, while the roadmap owns the
+proposed contract until then.

+# ADR-0010: Use workload-oriented LLM profile defaults
+
+**Status:** Accepted
+**Date:** 2026-08-03
+
+## Context
+
+LLM-backed D&D operations share an execution-policy choice, but repeating a
+provider or model-named profile on every module binding ties pipeline structure
+to a deployment decision. Different environments may require different model,
+backend, timeout, or reasoning settings while retaining the same workload.
+
+Notarius also needs a usable default for maintained D&D prompts without making
+an operator profile mandatory. That default must remain owned by the D&D
+family, while generic LLM infrastructure stays unaware of domain-specific
+policy.
+
+## Decision
+
+Pipelines may name one workload-oriented default profile, inherited only by
+selected LLM-backed bindings and validators. Binding-level profile IDs remain
+intentional exceptions, and the run-wide CLI profile override has highest
+precedence.
+
+The D&D family owns an embedded fallback profile named `dnd-extraction`.
+Operators may provide a complete profile with the same ID through a PromptKit
+filesystem source. PromptKit selects the higher-precedence matching definition;
+Notarius does not merge profile documents. Production, development, and local
+deployments can therefore use different execution policy behind one unchanged
+pipeline ID.
+
+## Alternatives considered
+
+- Repeat a model-named profile on every binding. This makes routine deployment
+  policy changes noisy and obscures the shared workload intent.
+- Require every deployment to install a profile file. This adds configuration
+  friction and leaves maintained D&D prompts without an application-owned
+  fallback.
+- Put D&D profile policy in generic LLM infrastructure. This breaks domain
+  ownership and makes generic code depend on one workload.
+
+## Consequences
+
+Pipeline configuration expresses workload intent rather than a specific
+provider or model. Operators can replace the complete execution policy without
+editing bindings, while binding-level and run-wide exceptions remain available.
+Profile changes affect resolved pipeline and checkpoint identity, so they may
+intentionally cause work to be recomputed. The D&D fallback becomes a
+maintained application execution-policy asset.

-`notarius run <pipeline-id>` executes a configured pipeline against one input
-file.
+~~~
+notarius run <pipeline-id> --input path/to/source.json [--json] [flags]
+~~~
 
-Flags:
+The **run** command executes the named pipeline for one input file. The
+pipeline ID and **--input** are required.
 
-- `--input path`: required source input file.
-- `--config path`: config file path. If omitted, Notarius uses the discovery
-  rules in [Configuration](config.md#discovery).
-- `--only lane-a,lane-b`: run only the named artifact lanes. Values are
-  comma-separated and must be non-empty. This retains its existing behavior for
-  implicit single-step pipelines; explicit multi-step pipelines reject it
-  rather than inferring dependency closure.
-- `--resume`: request checkpoint reuse for this invocation. Checkpoint recording
-  must be enabled in configuration. See
-  [Operations](operations.md#checkpoint-cache) for prerequisites and reuse
-  behavior.
-- `--recompute-step step-id`: with `--resume` and checkpoint recording enabled,
-  force the named ordered step and every transitive dependent lane to execute.
-  Compatible required predecessors and unrelated lanes remain reusable. The
-  value may identify an explicit step or the implicit single-step ID `default`;
-  it cannot be combined with `--only`.
-- `--chunk_cache auto|bypass|refresh`: select chunk-plan reuse for this
-  invocation. `auto` reuses a valid plan by canonical source digest, `bypass`
-  performs no plan-cache I/O, and `refresh` regenerates and replaces a valid
-  plan only after chunk validation succeeds. See
-  [Configuration](config.md#state-surfaces) for the persistent setting, precedence,
-  and cache-root selection.
-- `--output-dir path`: output root. Defaults to `./notarius-output`.
-- `--debug`: allocate and retain one debug bundle for this invocation.
-- `--debug-dir path`: debug-bundle root override. This flag requires `--debug`.
-- `--llm-profile id`: override every effective LLM-capable pipeline module
-  binding with one Scriptorium profile ID. Validator-specific profiles are not
-  overridden.
-- `--session-id id`: pass a stable prompt session identifier through LLM-backed
-  module calls.
-- `--reference selector=path`: bind a reference path to a chunk, extractor,
-  merger, or normalizer reference slot. Repeatable.
-- `--without-reference selector`: remove a configured optional reference binding.
-  Repeatable. It accepts the same selector forms as `--reference`, without
-  `=path`.
+| Flag | Meaning |
+| --- | --- |
+| **--config path** | Use this configuration file. When omitted, configuration discovery applies; see [Configuration](config.md). |
+| **--input path** | Source input file to process. Required. |
+| **--output-dir path** | Override the configured output root for this run. |
+| **--json** | Write the successful run-result receipt as JSON to standard output. |
+| **--chunk_cache auto\|bypass\|refresh** | Override chunk-plan cache handling for this run. |
+| **--resume** | Reuse compatible recorded checkpoints when checkpoint recording is enabled. |
+| **--recompute-step step-id** | With **--resume**, recompute the selected ordered step and its dependent lanes. It cannot be combined with **--only**. |
+| **--debug** | Retain a debug bundle for this run. |
+| **--debug-dir path** | Override the debug-bundle root. Requires **--debug**. |
+| **--only lane-a,lane-b** | Run only the selected comma-separated artifact lanes when that selection is valid for the configured pipeline. |
+| **--llm-profile id** | Highest-precedence configured profile for selected LLM-backed bindings and validators; it replaces binding and [pipeline](config.md#pipelines) defaults. |
+| **--session-id id** | Supply a non-empty prompt session identifier to LLM-backed module calls. |
+| **--reasoning-effort value** | Replace the selected PromptKit profile's reasoning effort for every LLM-backed call in this run. The value must be non-empty and the flag may be specified only once. |
+| **--clear-reasoning-effort** | Clear reasoning effort inherited from the selected PromptKit profile for every LLM-backed call in this run. |
+| **--reference selector=path** | Add or replace a file reference binding. Repeatable. |
+| **--without-reference selector** | Remove a configured optional reference binding. Repeatable. |
 
-On success, the command prints the completed pipeline ID, normalized output and
-rejected output counts, and the output directory. A debug-enabled run also
-prints `debug=<bundle-path>`. If the run completes with warnings, the warning
-count is printed to stderr.
+**--chunk_cache** accepts only **auto**, **bypass**, or **refresh**.
+**--debug-dir**, **--output-dir**, **--session-id**, and
+**--reasoning-effort**, and **--recompute-step** reject explicit empty values.
+**--reasoning-effort** and **--clear-reasoning-effort** are mutually exclusive.
+When neither is present, reasoning effort comes from the selected PromptKit
+profile. These controls apply to the shared run client, including retries and
+LLM-backed validators, and do not modify configuration or profile files.
+Persistent reasoning settings remain a PromptKit profile concern.
+**--recompute-step** requires **--resume**; checkpoint requirements and reuse
+behavior are documented in [Operations](operations.md).
 
-Reference flags are external file bindings resolved against selected chunk,
-extractor, merger, and normalizer targets before the run starts. Generated
-artifact bindings are configured in ordered steps and cannot be introduced by a
-CLI path flag. Flat slot names are accepted only
-when exactly one selected target declares that slot. For configured reference
-bindings, precedence, path resolution, and validation, see
-[Configuration](config.md#pipelines).
+### Reference selectors
 
-`--reference` binds or replaces one slot for one selected target. Selectors are:
+Use **--reference** only for a reference slot declared by the selected
+configured target. The accepted selector forms are:
 
-- `slot=path`: valid when exactly one selected target declares `slot`;
-- `chunk.slot=path`: target the chunker;
-- `merge.slot=path`: valid when exactly one selected merger declares `slot`;
-- `lane.slot=path`: valid when exactly one selected extractor, merger, or
-  normalizer in that lane declares `slot`;
-- `lane.extract.slot=path`: target a lane extractor;
-- `lane.merge.slot=path`: target a lane merger;
-- `lane.normalize.slot=path`: target a lane normalizer.
+| Form | Target |
+| --- | --- |
+| slot=path | The unique selected target that declares slot. |
+| chunk.slot=path | The chunker. |
+| merge.slot=path | The unique selected merger that declares slot. |
+| lane.slot=path | The unique extractor, merger, or normalizer in lane that declares slot. |
+| lane.extract.slot=path | The extractor in lane. |
+| lane.merge.slot=path | The merger in lane. |
+| lane.normalize.slot=path | The normalizer in lane. |
 
-Use `slot=path` when the selected targets declare the slot unambiguously:
+**--without-reference** uses the same selector forms without =path. Slot
+names, requiredness, and configured bindings are part of the
+[configuration contract](config.md).
 
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --reference roster=./campaign-roster.txt
-```
+### Run output
 
-Use an explicit selector when multiple selected targets declare the same slot or
-when you want to target a specific target:
+Without **--json**, standard output contains the completed pipeline ID, counts
+of normalized and rejected outputs, and the output directory. A debug-enabled
+run also prints its debug-bundle path to standard output. A successful run with
+warnings reports the warning count to standard error. The published JSON bundle
+is defined by the [JSON output contract](integrations/json-output.md).
 
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --reference spells.extract.glossary=./campaign-glossary.txt
-```
+With **--json**, successful standard output is exactly one
+`notarius.run-result.v1` JSON document followed by a newline, with no
+human-oriented status or debug-path line. Its fields and compatibility policy
+are defined by the [run-result contract](integrations/run-result.md). A caller
+must check for exit status 0 before decoding this output; a failed write can
+leave incomplete standard-output bytes that are not a result document.
 
-For the maintained NPC-grounded workflow, use the explicit ordered pipeline.
-The first step produces the normalized NPC artifact; the second step receives
-it in memory and fans it out to spell extraction, combat extraction, and combat
-normalization:
+Example:
 
-```sh
-go run ./cmd/notarius run dnd-npc-grounded \
-  --config examples/dnd-npc-grounded.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --output-dir ./npc-grounded-output
-```
+~~~
+OPENROUTER_API_KEY=your-api-key \
+  go run ./cmd/notarius run dnd-session \
+    --config examples/dnd-minimal.config.yml \
+    --input examples/seriatim-minimal-transcript.json
+~~~
 
-The generated NPC content remains contextual grounding, not spell or combat
-evidence. It is represented in manifests and debug summaries by bounded
-identity and producer provenance, not by payload content or a filesystem path.
+## config validate
 
-The same grammar can target chunk, merge, and normalize slots when the configured
-modules declare them:
+~~~
+notarius config validate [--config path/to/config.yml] [--pipeline pipeline-id] [--only lane-a,lane-b]
+~~~
 
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config path/to/config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --reference chunk.scene_guide=./campaign-scenes.txt \
-  --reference spells.merge.merge_notes=./merge-notes.txt \
-  --reference spells.normalize.normalization_notes=./normalization-notes.txt
-```
+This command loads and validates a configuration. With **--pipeline**, it also
+resolves that pipeline against the production module catalog. **--only** selects
+lanes during that resolution and requires **--pipeline**.
 
-Use `--without-reference` to remove a configured optional binding for a run:
-
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --without-reference glossary
-```
-
-Use `--session-id` when an external orchestrator needs all prompt calls from one
-run to share an identifier:
-
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --session-id campaign-17-session-04
-```
-
-When `cache.checkpoints.enabled` is `true`, runs record checkpoints whether or
-not `--resume` is present. Add the resume flag to load and reuse compatible
-recorded work; using it while checkpoint recording is disabled is an error:
-
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --resume
-```
-
-To selectively rerun one ordered step and its dependent lanes, use the step ID
-from the configuration. The selected step and dependents are reported as
-`forced_recompute`; reusable predecessors are reported as `reused`:
-
-```sh
-go run ./cmd/notarius run dnd-npc-grounded \
-  --config examples/dnd-npc-grounded.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --resume --recompute-step grounded-events
-```
-
-Checkpoint decisions use these categories: `reused`, `executed`,
-`forced_recompute`, and `dependency_invalidated`. The reason code and bounded
-detail identify the decision without exposing reference content, local paths,
-or secrets. `--recompute-step` requires checkpoint recording and `--resume`;
-unknown step IDs, empty values, and combinations with `--only` are rejected.
-The operator meanings of checkpoint reason codes are maintained in
-[Operations](operations.md#resume-and-selective-recompute).
-
-Use `--debug` to retain the redacted summary and trace bundle for one run. The
-bundle is allocated before pipeline resolution; once allocated, its path is
-also printed to stderr if the command fails. Debug-write failures cause exit
-code `1`.
-
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --debug --debug-dir ./notarius-debug
-```
-
-Use `refresh` when intentionally replacing the cached plan for the same source:
-
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --chunk_cache refresh
-```
-
-Use `bypass` for a one-off run that must not inspect or create plan-cache state:
-
-```sh
-go run ./cmd/notarius run dnd-session \
-  --config examples/dnd-spells.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --chunk_cache bypass
-```
-
-`--diagnostics-dir` has been removed. For checkpoint behavior, durable output,
-debug-bundle lifecycle, and failure inspection, see [Operations](operations.md).
-
-## `config validate`
-
-`notarius config validate` loads and validates configuration.
-
-Flags:
-
-- `--config path`: config file path. If omitted, Notarius uses the discovery
-  rules in [Configuration](config.md#discovery).
-- `--pipeline pipeline-id`: additionally resolve one configured pipeline against
-  the production module catalog.
-- `--only lane-a,lane-b`: validate resolution for selected artifact lanes. This
-  flag requires `--pipeline`.
+Success is written to standard output as either config "<path>" is valid or

+    --config examples/dnd-complete.config.yml \
+    --pipeline dnd-session
+~~~
 
-## `pipelines list`
+The placeholder in the second command is sufficient only for offline
+validation; it cannot run a provider-backed pipeline.
 
-`notarius pipelines list` prints configured pipeline IDs in sorted order.
+## pipelines list
 
-Flags:

+~~~
 
-- `--config path`: config file path. If omitted, Notarius uses the discovery
-  rules in [Configuration](config.md#discovery).
-- `--json`: print `{"pipelines":[...]}` instead of one ID per line.
+This command lists configured pipeline IDs in sorted order. By default, it
+writes one ID per line to standard output. **--json** writes an object shaped as
+{"pipelines":[...]} instead.
 
-Examples:
-
-```sh
+~~~
 go run ./cmd/notarius pipelines list \
-  --config examples/dnd-spells.config.yml
+  --config examples/dnd-minimal.config.yml
+~~~
 
-go run ./cmd/notarius pipelines list \
-  --config examples/dnd-spells.config.yml \
-  --json
-```
+## Output Streams And Exit Statuses
 
-## Exit Codes
+Successful commands write their primary result to standard output. Warnings and
+errors are written to standard error.
 
-- `0`: command succeeded.
-- `1`: command syntax was valid, but loading config, resolving modules, running
-  the pipeline, calling the provider, writing output, or writing a requested
-  debug bundle failed.
-- `2`: command syntax was invalid, a command was unknown, a required argument
-  was missing, or a flag value was malformed.
+For **run --json**, warnings remain on standard error and standard output is a
+machine-readable success result only. Syntax and runtime diagnostics remain on
+standard error. Parse the result only after the process exits with status 0.
 
-For YAML structure, defaults, Scriptorium profile sources, environment
-overrides, and selectable module and validator keys, see
-[Configuration](config.md).
+| Status | Meaning |
+| --- | --- |
+| 0 | The command completed successfully, including root help. |
+| 1 | Command syntax was valid but configuration loading or validation, pipeline resolution or execution, provider use, output, or requested debug handling failed. |
+| 2 | The command or flag syntax was invalid, including unknown commands, missing required arguments, invalid flag values, or invalid flag combinations. |
+
+The root help spellings are the supported help path. Invoking **--help** on
+**run**, **config validate**, or **pipelines list** is handled by the flag
+parser as a usage error: it writes an error to standard error and exits with
+status 2.

+Use this workflow when an orchestrator runs Notarius and consumes its published
+artifacts. The [CLI reference](../cli.md) owns invocation syntax and exit
+statuses, while the [run-result receipt](../integrations/run-result.md) and
+[Published JSON Output contract](../integrations/json-output.md) own the
+durable result formats.
+
+## Run And Check The Process
+
+Optionally preflight a selected configuration and pipeline before work starts:
+
+```sh
+notarius config validate --config /path/to/notarius.yml --pipeline pipeline-id
+```
+
+Invoke the run with explicit paths and machine-readable output. Capture
+standard output and standard error separately; do not combine them before
+processing the result.
+
+```sh
+notarius run pipeline-id \
+  --config /path/to/notarius.yml \
+  --input /path/to/source.json \
+  --output-dir /path/to/output-root \
+  --json
+```
+
+Use absolute paths for supplied input, configuration, output-root, and
+reference files. When a stable prompt session identifier or references are
+needed, pass the supported CLI flags. Supply credentials through Notarius's
+documented configuration and environment mechanisms, never as command-line
+arguments or generated secret-bearing configuration.
+
+Wait for the process before interpreting standard output. Only an exit status
+of 0 permits decoding the receipt. On a nonzero exit, retain standard error for
+diagnosis and ignore all standard-output bytes: a failed receipt write may have
+left a partial document.
+
+## Discover Required Artifacts
+
+Decode the successful receipt and accept the schema versions supported by the
+caller. Use its `output_directory` as the bundle root. For the production JSON
+output, resolve `index_file` under that root with a confinement check and reject
+an absolute path or a result that escapes the root.
+
+Read the resulting `index.json` and locate each artifact by `lane_id`, not by a
+guessed filename. Before decoding a selected payload, verify its descriptor's
+media type and schema identity against the relevant published artifact
+contract. The JSON bundle contract links to the available lane contracts.
+
+If `index.json` has an `evidence_context` descriptor, treat it as a
+pipeline-wide artifact rather than a lane entry. Verify its six descriptor
+fields before decoding the linked file according to the [Published Evidence
+Context contract](../integrations/evidence-context.md). Use each
+`evidence_refs` entry as the citation to source material. Its surrounding
+context range and included units explain the citation, but do not widen or
+replace the cited source reference.
+
+A zero exit status may still report rejected outputs, warnings, or absent
+lanes. The caller decides which lane IDs are required for its own work and
+which are optional; it should make that decision explicitly rather than infer
+failure from the receipt counts alone.
+
+## Preserve Provenance And Handle Data Carefully
+
+Keep the receipt with the published `manifest.json`, and retain
+`rejected.json` and `warnings.json` when review or later provenance requires
+them. Treat the input, output bundle, cache, debug bundle, and captured process
+logs as potentially sensitive data. Apply the caller's access controls and
+retention policy, and avoid copying secrets into arguments, logs, or
+provenance records. An evidence-context artifact contains source-unit text and
+metadata, and selected lanes can cover most of an input; preserve and share it
+only when that source content is authorized for the recipient.

+# Accepted Chunk Map
+
+This document defines the optional durable `chunk-map.json` artifact in a
+[published JSON bundle](json-output.md). It describes the accepted,
+materialized chunk plan used by one run. It is not a lane payload and is never
+an input to a later pipeline step.
+
+## Contract Identity
+
+| Property | Value |
+| --- | --- |
+| Artifact kind | `source/chunk-map` |
+| Logical file | `chunk-map.json` |
+| Media type | `application/json` |
+| Schema ID | `notarius.source.chunk_map` |
+| Schema name | `notarius_source_chunk_map_v1` |
+| Schema version | `v1` |
+
+The optional `chunk_map` descriptor in `index.json` identifies this artifact.
+Export is controlled by the JSON output binding described in
+[Configuration](../config.md#module-bindings-and-validators).
+
+## Wire Shape
+
+Every payload has these required fields:
+
+| Field | Meaning |
+| --- | --- |
+| `source_id` | Accepted source-document identity. |
+| `source_digest` | Lower-case `sha256:` digest of that source document. |
+| `plan_digest` | Lower-case `sha256:` digest of the logical chunk plan. |
+| `requested_chunker` | Chunk module selected by the resolved pipeline. |
+| `producer` | Original accepted-plan producer. `input_module` and `chunk_module` are required; `llm_profile` is optional. |
+| `plan_annotations` | Plan-level annotation namespace map; `{}` when none are present. |
+| `chunks` | Non-empty execution-order chunk collection. |
+
+Each `chunks` entry contains non-empty `id`, zero-based `index`, `source_ref`,
+positive `unit_count`, and an explicit `annotations` map. `source_ref` contains
+the same `source_id` as the top-level value plus positive inclusive
+`start_unit_id` and `end_unit_id` values. Endpoints identify source units; their
+numeric values do not by themselves establish source-document order.
+
+Annotation namespaces are non-empty trimmed strings. Their values are arbitrary
+valid JSON and are retained without interpreting a module-specific namespace.
+
+## Ordering And Validation
+
+`chunks` are in execution order. Their indexes are contiguous, start at zero,
+and equal their array positions; chunk IDs are unique. The emitted map is built
+only after the selected plan has been accepted and materialized against the
+source document, so its ranges, unit counts, annotations, and digests describe
+that exact plan.
+
+The codec rejects malformed JSON, trailing content, unknown fixed-object
+fields, invalid identities or digests, invalid annotations, duplicate chunk
+IDs, non-contiguous indexes, and a `plan_digest` that does not match the
+reconstructed logical plan. The checked-in
+[schema](../../internal/framework/chunkmap/assets/schemas/source_chunk_map.v1.json)
+defines the strict JSON shape.
+
+## Valid Example
+
+The compact
+[source chunk-map fixture](../../internal/framework/chunkmap/testdata/source_chunk_map.v1.json)
+is decoded by the production codec and demonstrates an accepted map with
+annotations, producer identity, and ordered chunks.
+
+## Publication And Compatibility
+
+The map is present only when a chunk plan was accepted and its export is
+enabled. It remains publishable if a later lane is rejected, but is absent when
+chunk-plan validation rejects the plan. `requested_chunker` identifies the
+current pipeline selection, while `producer` identifies the component that
+originally produced the accepted plan; they may differ when an accepted plan is
+reused.
+
+The map contains structure rather than source content: it excludes transcript
+bytes, source-unit metadata, chunk text, private model output, reference
+content, debug data, and filesystem paths. Treat the exported map with the
+same care as other published output. Publication location and retention are
+defined in [Operations](../operations.md#output-bundles).

 ```json
 {
-  "source_id": "session-alpha",
-  "start_unit_id": 1,
-  "end_unit_id": 2
+  "combat_turns": [
+    {
+      "actor": "Mira Thorn",

 }
 ```
 
-`source_id` must be non-empty and both unit IDs must be positive integers. The
-codec does not resolve references against a source document or enforce source
-range ordering; those checks belong to the later source-reference validation
-boundary.
+## Eligibility, evidence, and normalized form
 
-## Codec behavior
+The extractor requires an approved [scene-description artifact](dnd-scene-description-artifacts.md).
+It emits combat turns only for a chunk with an exact matching scene classified
+`combat`; an exact non-combat scene produces an accepted empty list. The scene
+record controls eligibility only: its title, summary, and reference do not
+become turn evidence. No exact matching scene also produces an empty list and
+the `scene_classification_unavailable` warning.
 
-The codec exposes two representations of the same typed artifact:
+An optional normalized [NPC artifact](dnd-npc-artifacts.md) can ground an
+actor name. Its registry references are provenance, never combat evidence.
+Normalization trims and, where possible, canonicalizes actor names; orders and
+deduplicates exact source references; orders valid-evidence turns by source
+chronology; and collapses only duplicates with the same actor identity, turn
+kind, and complete valid evidence. It does not infer turns, initiative, or
+actions from registry or scene data.
 
-- Candidate encode/decode preserves invalid enum values, nullable values,
-  required-array presence, required strings, targets, and source references so
-  later validators can report them. Candidate decoding still requires valid
-  JSON, one JSON value, known fields, and the explicitly present `round` and
-  `resolution` keys; `null` is distinct from a missing key.
-- Approved encode/decode enforces the structural rules in this contract.
-
-The codec owns the durable JSON Schema, whose object layers all set
-`additionalProperties` to `false`. Codec metadata contains only
-`combat_turn_count`.
-
-The maintained compact fixture is
-`internal/modules/dnd/codec/combatturns/testdata/dnd_combat_turns.v1.json`.
-
-## Extraction boundary
-
-The standalone extractor uses these identities:
-
-| Property | Value |
-| --- | --- |
-| Extractor key | `dnd/combat-turns` |
-| Capability | `dnd.combat_turns` |
-| Prompt ID | `dnd.combat_turns` |
-| Prompt version | `v1` |
-| Private response-schema key | `dnd_combat_turns_llm` |
-| Private response-schema ID | `notarius.dnd.combat_turns.llm` |
-| Default profile | `gemini-2-flash` |
-
-It requires `chunks` and `source.transcript`, accepts no options, and makes one
-structured completion for each supplied chunk. The prompt receives the
-chunk-scoped transcript plus the existing `players`, `party`, and `glossary`
-inputs, and optionally the deprecated `roster` reference through the shared
-party mapping. The optional `npcs` reference is an approved normalized NPC
-artifact used only for identity grounding; it never supplies combat evidence.
-An external file is validated during preparation. In an ordered pipeline, the
-same slot may receive the producer's canonical generated artifact at the step
-handoff.
-
-The private response envelope has the same fields and JSON types as the durable
-turn/action shape except that source references contain only `start_unit_id`
-and `end_unit_id`. It enforces required and nullable field presence, types, and
-unknown-field rejection, while deterministic validators own enum membership,
-non-empty values and collections, and positive-number requirements. The
-extractor assigns the current source ID, removes exact duplicate ranges, and
-stable-sorts turns by the earliest valid source-document position. Numeric unit
-IDs are identifiers; source-document slice position determines chronology.
-Semantically malformed candidate fields remain in the typed result for the
-configured validation and retry boundary.
-
-## Deterministic candidate validation
-
-The standalone validator keys are:
-
-| Validator | Responsibility |
-| --- | --- |
-| `extract/dnd/combat-turns/shape` | Required arrays, strings, nullable fields, positive rounds, and supported enum values. |
-| `extract/dnd/combat-turns/source_refs` | Source identity, source-unit existence, and range order through the source document. |
-| `extract/dnd/combat-turns/source_relatedness` | At most one advisory warning per turn when the actor or declared action is not related to cited transcript text. |
-
-Source-reference and relatedness validators defer malformed shape to the shape
-validator. Relatedness also defers when any cited source range is invalid. It
-combines overlapping cited ranges once in document order, compares actors with
-the shared Unicode-aware NPC identity policy, and checks declaration tokens of
-at least four Unicode code points against complete cited-text tokens. Targets
-are not checked deterministically.
-
-The production D&D registrar exposes the extractor and these validators. Its
-default extraction chain preserves this order: JSON syntax, private response
-schema, combat shape, source references, then source relatedness.
-
-## Normalization boundary
-
-The standalone normalizer uses key `dnd/combat-turns`, requires `merged`,
-provides `normalized`, accepts no options, and accepts only the optional
-structured `npcs` reference. Campaign references are LLM extraction context and
-are not normalizer inputs. For an external file, the NPC registry is resolved
-during preparation; for a generated binding, it is resolved at the operation-
-time handoff. Runtime normalization uses that immutable prepared or handed-off
-view.
-
-Normalization policy is `dnd.combat_turns.normalize.v1`. It display-normalizes
-actor, summary, declarations, targets, and non-null resolutions; canonicalizes
-exact registry actor and target matches; orders and deduplicates exact source
-references; stable-sorts records by earliest valid source-document position; and
-collapses only records with the same actor identity, turn kind, round value, and
-complete valid evidence set. The first normalized record is retained without
-merging its actions or prose. Invalid evidence is never eligible for duplicate
-collapse. Every mutation and collapse emits a bounded warning using the merged
-input index in its scope.
-
-The normalizer reports `normalization_policy` and `identity_policy` metadata
-and fingerprints. An external registry may additionally contribute
-`npc_registry_digest` and `npc_count`; generated registry identity is retained
-in framework handoff provenance and dependency fingerprints. The
-normalized-invariants validator is
-`normalize/dnd/combat-turns/invariants`; it defers shape and source-reference
-failures, then checks display normalization, target identity uniqueness,
-canonical evidence ordering, chronology, and duplicate identity. It rejects
-with `invalid_combat_turn_normalization` under policy
-`dnd.combat_turns.validator.normalized.v1`.
-
-The production D&D registrar exposes the normalizer and normalized-invariants
-validator. Its default normalization chain is JSON syntax, durable schema,
-combat shape, normalized invariants, source references, then source
-relatedness. The lane uses the framework's typed append-order merger and has no
-merge validator chain.
-
-## Production manifest and references
-
-The selectable lane uses extractor and normalizer key `dnd/combat-turns`,
-`appendorder` for the typed merger, and the durable codec above. A bound `npcs`
-reference contributes raw-file provenance to the run manifest. A generated
-binding contributes artifact kind, schema identity, media type, canonical
-digest, size, and bounded producer provenance. Consumer metadata and checkpoint
-fingerprints contain no registry names, aliases, content, paths, or NPC source
-ranges. The normalized lane is emitted as `lanes/<lane-id>.json` by the JSON
-output module, and warnings and rejection summaries remain in their shared
-companion files.

+broader NPC occurrences. The [JSON output contract](json-output.md) defines
+publication, and [D&D module internals](../internal/dnd.md) describes routing

 # D&D NPC Artifact
 
-This document defines the durable D&D NPC-list artifact, its JSON codec, and
-the selectable production NPC pipeline. The normalized JSON payload can be
-passed explicitly to the spell extractor as an optional caster-name registry
-or to the combat extractor and normalizer as an actor/target registry. It
-remains a reference, not spell or combat evidence.
+This contract defines the durable NPC registry produced by `dnd/npcs`. It is a
+minimal, source-grounded identity registry for other D&D artifacts, not a
+character sheet or a relationship summary.
 
-## Identity
+## Identity and compatibility

-The durable JSON Schema is owned by the D&D NPC codec. NPC IDs are derived from
-the Unicode-normalized, case-folded canonical name using the identity policy.
-The durable codec enforces the artifact shape and ID syntax; registry identity
-validation remains a separate deterministic concern.
+`v1` accepts one strict JSON object with required `npcs`; the array may be
+empty. NPC and source-reference objects reject unknown fields. An incompatible
+artifact shape or identity-policy change uses a new version or policy.
 
-## Output Shape
+## Wire shape and identity
 
-The payload is one object with a required top-level `npcs` array:
+Each NPC has these required fields:
+
+| Field | Contract |
+| --- | --- |
+| `id` | `npc:sha256:` followed by 64 lowercase hexadecimal characters. |
+| `name` | Non-empty canonical display name. |
+| `source_refs` | One or more transcript evidence ranges for the identity. |
+
+A source reference has exactly `source_id`, `start_unit_id`, and `end_unit_id`.
+The source ID identifies the transcript, unit IDs are positive inclusive unit
+identifiers, and the start may not follow the end.
 
 ```json
-{"npcs": []}
+{
+  "npcs": [
+    {
+      "id": "npc:sha256:99a16589618a04f535a7d21fdcc71a0b1c05d22f752cd492065b1086d97bc3d7",
+      "name": "Mira Thorn",
+      "source_refs": [
+        {"source_id": "session-7", "start_unit_id": 4, "end_unit_id": 5}
+      ]
+    }
+  ]
+}
 ```
 
-The array may be empty. Every object and nested object rejects unknown fields.
+The ID is deterministic: normalize the name to Unicode NFKC, normalize the
+supported apostrophe forms, collapse whitespace, case-fold it, SHA-256 the
+result, then prefix the lowercase hexadecimal digest with `npc:sha256:`. Each
+canonical identity and ID appears at most once. Normalization collapses records
+with the same canonical identity, retains their earliest position, and merges
+their canonicalized evidence; it does not add aliases, roles, descriptions, or
+relationship fields.
 
-## NPC Fields
+## Scope and consumers
 
-Each NPC contains exactly these required fields:
+Only individually identifiable NPC names with transcript evidence belong in
+this artifact. Groups, generic roles, invented labels, and descriptive
+enrichment are excluded. Its source references prove registry provenance; they
+do not become evidence for a spell, interaction, or combat occurrence.
 
-- `id`: `npc:sha256:` followed by 64 lowercase hexadecimal characters;
-- `name`: the canonical display name;
-- `aliases`: an array of alternate display names, which may be empty;
-- `description`: a concise description;
-- `relationships`: an array of target/relationship objects, which may be empty;
-- `source_refs`: at least one source reference supporting the NPC record.
-
-Each relationship contains required `target` and `relationship` strings. Each
-source reference contains required `source_id`, `start_unit_id`, and
-`end_unit_id`; unit IDs are positive integers. Source document identity, unit
-existence, and range ordering are validated by the source-reference validator
-when the artifact is used by a pipeline.
-
-## Codec Boundary
-
-`EncodeCandidate` and `DecodeCandidate` provide strict single-value JSON
-serialization while preserving typed values that still need semantic
-validation. `Encode` and `Decode` are the approved-artifact boundary and
-require all durable structural fields, non-empty required strings, valid source
-reference shapes, and the NPC ID pattern.
-
-Codec metadata contains only `npc_count`. Schema bytes and returned metadata
-are independent values so callers cannot mutate codec-owned state.
-
-## Production Pipeline
-
-The production identities are:
-
-- extractor: `dnd/npcs`;
-- artifact kind: `dnd/npc-list`;
-- normalizer: `dnd/npcs`; and
-- durable schema: `notarius.dnd.npcs`, version `v1`, media type
-  `application/json`.
-
-The extractor maps private model records to the current source identity and
-assigns deterministic IDs. Extraction validation checks shape, source
-references, and source relatedness. The normalizer then consolidates records
-by canonical identity or canonical-name/alias matches, preserves the first
-record's display and output position, unions relationships and exact evidence,
-rewrites unambiguous relationship targets to canonical names, and validates
-the retained registry's identity. No LLM is used for consolidation.
-
-The default extraction chain is `generic/valid_json`,
-`generic/valid_json_schema`, `extract/dnd/npcs/shape`,
-`extract/dnd/npcs/source_refs`, and
-`extract/dnd/npcs/source_relatedness`. The normalize chain adds
-`normalize/dnd/npcs/identity` before the source-reference and relatedness
-checks. Relatedness emits bounded warnings when an NPC canonical name or
-alias is not present near its cited transcript text; opaque campaign
-references may explain such a warning but do not become evidence.
-
-## Manifest And Artifact Handoff
-
-The NPC extractor records prompt and response-schema identities. The durable
-codec records only `npc_count`; raw names, aliases, descriptions, source
-references, and payload bytes stay in the lane file rather than manifest
-metadata. The normalized lane can be consumed by a later ordered step through
-the registered canonical codec:
-
-```yaml
-steps:
-  - id: identify-npcs
-    artifacts:
-      npcs:
-        extract: dnd/npcs
-        normalize: dnd/npcs
-  - id: grounded-events
-    references:
-      npcs:
-        artifact:
-          step: identify-npcs
-          lane: npcs
-    artifacts:
-      spells:
-        extract: dnd/spells
-        normalize: dnd/spells
-      combat:
-        extract: dnd/combat-turns
-        normalize: dnd/combat-turns
-```
-
-The framework hands only an accepted normalized artifact across the barrier. It
-validates the canonical bytes against each consumer slot and clones the
-operation-time reference for the spell and combat consumers. Generated
-provenance records the artifact kind, schema identity, media type, canonical
-digest, size, and producer step/lane/module, but not names, aliases, source
-ranges, or payload bytes. External normalized files remain supported as
-explicit references and retain their file provenance.
-
-NPC source references are registry provenance and are never accepted as spell
-or combat evidence. Current transcript units remain the only event evidence.
+This registry can ground actor or caster names in the [spell](dnd-spell-artifacts.md)
+and [combat-turn](dnd-combat-turn-artifacts.md) artifacts. It is required to
+resolve the canonical `name` in an [NPC interaction](dnd-npc-interaction-artifacts.md).

+| `name` | Non-empty canonical display name from the required NPC registry. |
+| `kind` | One of the interaction categories below. |
+| `source_refs` | One or more transcript evidence ranges. |
+
+Each source reference has exactly `source_id`, `start_unit_id`, and
+`end_unit_id`. It identifies an inclusive range in the current transcript;
+unit IDs are positive and the start may not follow the end. Extraction evidence
+for an interaction is confined to its accepted chunk.

+
+## Interaction categories
+
+| Kind | Meaning |
+| --- | --- |
+| `mentioned` | The NPC is referred to but is not established as present or communicating. |
+| `noncombat_presence` | The NPC is present and relevant without meaningful dialogue or combat participation. |
+| `dialogue` | The NPC speaks, responds, or meaningfully participates in a non-combat exchange. |
+| `combat_ally` | The NPC actively participates in combat on the party's side. |
+| `combat_opponent` | The NPC actively participates in combat against the party. |
+| `other` | A clearly evidenced direct occurrence not covered by another category. |
+
+The categories do not represent motives, relationships, state, or events that
+the cited transcript does not establish. An `other` entry is not a substitute
+for uncertain classification.
+
+## Identity, evidence, and order
+
+The required normalized [NPC artifact](dnd-npc-artifacts.md) resolves `name`.
+Registry references are provenance only and never replace an interaction's own
+evidence. Normalization canonicalizes recognized registry names, orders and
+deduplicates exact source references, then orders interactions by valid source
+chronology, NPC comparison identity, display name, kind, and reference sequence.
+Only entries with the same canonical name, kind, and complete valid evidence
+sequence are collapsed; distinct categories or evidence remain separate.

+occurrences and the [JSON output contract](json-output.md) for publication.

+
+## Meaning and normalized form
+
+`combat` identifies a chunk where active combat is the central activity.
+`narrative` is current in-world play that is not principally combat, recap, or
+meta discussion. `recap` is primarily a recounting of an earlier session, and
+`meta` is primarily out-of-character discussion. The artifact does not add
+participants, confidence, events, or information absent from the chunk.
+
+Normalization trims title and summary, orders scenes by source position and
+then ID, and removes exact duplicate records. A reused ID with different
+durable fields, or the same source range with different kind, title, or
+summary, is invalid. It does not merge adjacent ranges, alter prose, or infer
+missing scenes.
+
+The [combat-turn artifact](dnd-combat-turn-artifacts.md) uses an exact matching
+`combat` scene only as eligibility control; scene title, summary, and source
+reference never become combat evidence. Publication is defined by the

 # D&D Spell Artifact
 
-This document is the durable serialized artifact contract for the production
-D&D spell extractor. Selectable extractor keys are cataloged in
-[Configuration](../config.md#implemented-production-modules).
+This contract defines the durable output of the `dnd/spells` extractor and
+normalizer. It records source-grounded spell-casting occurrences; it is not a
+spellbook, a rules lookup result, or a record of hypothetical casts.
 
-## Identity
+## Identity and compatibility
 
-- Artifact kind: `dnd/spell-list`
-- Prompt ID: `dnd.spells`
-- Response schema key: `dnd_spells`
-- Response schema ID: `notarius.dnd.spells`
-- Response schema name: `notarius_dnd_spells_v1`
-- Response schema version: `v1`
-- Media type: `application/json`
-
-The durable JSON Schema is owned by the D&D spell artifact codec. The
-extractor's private LLM response schema is a separate transport contract: its
-source-reference objects omit `source_id`, which the extractor assigns while
-mapping the response to the canonical artifact. The LLM DTO and transport
-schema are not part of this durable contract.
-
-The output contains canonical spell casts derived from transcript evidence.
-Source IDs are assigned from the input identity; source-unit ranges identify
-the evidence location.
-
-## Output Shape
-
-The extractor payload is a JSON object with one required top-level array. Its
-structure is:
-
-```text
-{"spell_casts": [<spell-cast object>, ...]}
-```
-
-`spell_casts` must be present. It may be empty when no spell casts are found.
-When multiple chunk results are combined, spell casts remain in chunk order.
-When the payload is written as durable output, its logical path is derived from
-the configured artifact lane ID as defined by the
-[JSON output contract](json-output.md#output-payload-files).
-
-## Spell-Cast Fields
-
-Each spell cast contains exactly these required fields:
-
-- `caster`: in-world character or creature casting the spell;
-- `spell`: spell name;
-- `effect`: concise spell effect in the scene;
-- `narrative_description`: short description of the spell cast in context;
-- `source_refs`: transcript source references with extractor-assigned source
-  IDs and evidence unit ranges. It must contain at least one entry.
-
-All four string fields must be non-empty. `caster` is the canonical in-world
-caster, not the human player, transcript speaker, or GM when the associated
-character or creature can be identified. Player and party references may
-disambiguate that identity, but do not independently establish that a cast
-occurred. The `spell` value must resolve through the effective SRD-plus-overlay
-catalog as either a canonical name or alias. Catalog validation accepts aliases
-but does not rewrite them; unknown fields are rejected.
-
-`effect` and `narrative_description` record the casting declaration and its
-immediate resolution as established by the transcript. They do not follow
-summoned creatures, persistent spell effects, or other downstream consequences
-through the rest of the scene. They also do not correct the table from
-published D&D rules or supplement the transcript with model knowledge. When the
-transcript contains a nonstandard or disputed ruling, the artifact may preserve
-the immediate observed resolution and attribute relevant reasoning to the GM or
-table; it must not present that reasoning as a universal game rule. The spell
-catalog is name-recognition policy, not evidence for spell mechanics or
-outcomes.
-
-## Source References
-
-Each source reference contains exactly three required fields: `source_id`,
-`start_unit_id`, and `end_unit_id`. The source ID must match the input identity.
-The unit IDs must be positive integers present in the input, and the start unit
-must not appear after the end unit. Unknown fields are rejected.
-
-For each cast, the complete `source_refs` collection identifies the transcript
-evidence for every factual claim in `caster`, `spell`, `effect`, and
-`narrative_description`. A cast declaration and its immediate resolution may be
-cited with separate narrow ranges when intervening units are unrelated. A
-reported target, roll, amount, condition, interruption, or immediate outcome
-must be supported by the cited units; otherwise the artifact describes only the
-supported attempt or declaration. Later behavior by summoned creatures,
-recurring effects, and other downstream consequences are outside the cast
-artifact's evidence scope. The deterministic validators establish that ranges
-are structurally valid and that the spell name is related to cited text.
-Semantic claim completeness is an extraction policy and remains subject to
-evaluation rather than deterministic proof.
-
-Reference slot keys and accepted file types are defined in
-[Configuration](../config.md#implemented-production-modules). References are
-supporting disambiguation material, not source evidence, and are not
-addressable through `source_refs`.
-
-## Optional NPC Grounding
-
-The `dnd/spells` extractor accepts an optional `npcs` reference containing one
-normalized NPC artifact as `application/json`, up to 1 MiB. An external file is
-validated during preparation; an ordered generated binding is validated at the
-step handoff. Both paths use the approved NPC codec and identity policy,
-re-encode canonical durable JSON, and supply that JSON as an operation-time
-spell prompt input. It helps the model prefer canonical caster names and
-recognize aliases; it does not establish that a spell was cast.
-
-NPC source references may identify the run that produced the registry or any
-other session. They remain registry provenance and are never copied into a
-spell cast's `source_refs`; every spell evidence range must still identify the
-current transcript. Generated provenance records producer and canonical
-artifact identity without payload content or a path. When the slot is absent,
-the prompt receives exactly `{"npcs":[]}` and the run has no NPC reference
-provenance or NPC checkpoint fingerprint.
-
-## Normalization Behavior
-
-When the `dnd/spells` normalizer is selected, each recognized spell name is
-rewritten to the effective catalog's canonical display name. Lookup uses the
-catalog's case-insensitive, whitespace-normalizing, apostrophe-normalizing, and
-alias rules. Unknown names are preserved exactly for the normalize validators;
-the normalizer does not guess or apply fuzzy matching.
-
-Each cast's `source_refs` is copied, sorted by exact `source_id`,
-`start_unit_id`, and `end_unit_id`, and stripped of exact structural
-duplicates. Adjacent or overlapping ranges are not merged, and the normalizer
-does not synthesize references or change their boundaries.
-
-After those per-cast changes, duplicate identity requires the same canonical
-spell name, the same caster after case folding and whitespace normalization,
-and the same complete, non-empty set of source references valid for the source
-document. Only the first occurrence is retained, in stable order. Its caster,
-effect, narrative description, and canonical references are preserved without
-prose merging or source union. Unknown names, empty or invalid evidence, and
-casts with different evidence remain separate.
-
-Mutation and duplicate decisions are returned through the normal warnings
-surface. Warning scopes use the merged input index, such as `spell_casts[0]`,
-so they remain meaningful even when a later duplicate is removed. The
-normalizer uses these reason codes:
-
-| Reason code | Meaning |
+| Property | Value |
 | --- | --- |
-| `spell_name_canonicalized` | A catalog lookup replaced an input name with its canonical display name. |
-| `spell_name_unresolved` | A name was not found in the effective catalog and was retained unchanged. |
-| `source_references_normalized` | Reference order changed or exact duplicate references were removed. |
-| `duplicate_spell_cast_collapsed` | A later cast matched the retained cast's complete duplicate identity. |
+| Artifact kind | `dnd/spell-list` |
+| Schema ID | `notarius.dnd.spells` |
+| Schema name | `notarius_dnd_spells_v1` |
+| Schema version | `v1` |
+| Media type | `application/json` |
 
-Only warnings from an accepted normalize attempt are promoted to
-`warnings.json`. If an unresolved name reaches the default normalize validator
-chain, the catalog validator rejects the candidate with `unknown_spell`; the
-`spell_name_unresolved` warning remains in the attempt's debug artifact. An
-explicit validator override that accepts the candidate promotes the unresolved
-warning normally.
+`v1` is a single strict JSON object. It requires `spell_casts`; the array may
+be empty. Each spell-cast object and source-reference object rejects unknown
+fields. An incompatible shape change requires a new schema version.
 
-## Manifest Metadata
+## Wire shape
 
-The extractor adds prompt and response-schema provenance under the artifact lane
-manifest metadata:
+Each `spell_casts` entry has these required fields:
+
+| Field | Contract |
+| --- | --- |
+| `caster` | Non-empty in-world character or creature name. |
+| `spell` | Non-empty spell name. |
+| `source_refs` | One or more transcript evidence ranges. |
+
+Every source reference has exactly `source_id`, `start_unit_id`, and
+`end_unit_id`. The source ID identifies the input transcript; the unit IDs are
+positive inclusive unit identifiers, and the start may not follow the end in
+that source. References are evidence for the cast, not campaign-reference or
+NPC-registry provenance.

-`catalog_digest` identifies the effective semantic catalog, while
-`catalog_overlay_ids` is sorted and empty for a base-only configuration. Raw
-prompt, schema, catalog, alias, and local overlay-file content are not
-included in manifest metadata. The `normalizer` metadata uses the same catalog
-identity fields when that module is selected. Overlay origin, media type, byte
-size, and raw digest are recorded separately in the manifest's reference
-provenance; see the [JSON output contract](json-output.md#manifestjson).
+## Evidence and normalized form
 
-The `npc_registry_digest` and `npc_count` fields in the example are present for
-an external NPC registry when the extractor publishes its prepared module
-metadata. They contain no NPC names, aliases, source references, paths, or raw
-bytes. A generated registry's identity is instead represented by the framework
-handoff provenance and dependency fingerprint, so the consumer module metadata
-does not duplicate it.
+An entry represents an actual cast or an unambiguous declared attempt. A spell
+mention, rules discussion, plan, or catalog match alone is not an occurrence.
+The configured catalog checks the name; it does not establish evidence.
 
-The extractor's prompt hash, private response-schema hash, and effective catalog
-digest also contribute independently scoped semantic checkpoint fingerprints.
-Changing any of those prepared contracts intentionally produces a cold
-checkpoint miss. Fingerprints contain only digests, never prompt, schema,
-catalog, or reference content. When an NPC registry is bound, its semantic
-digest contributes an additional local `npc_registry` fingerprint for an
-external binding; the manifest metadata contains only that digest and
-`npc_count`. Raw NPC file provenance remains independently recorded in the
-manifest's `references` list. Generated bindings contribute the canonical
-artifact dependency fingerprint and bounded producer provenance instead.
+When normalization is selected, recognized spell names use the effective
+catalog's canonical display name. Source references are put in canonical source
+order and exact duplicate references are removed. A later entry is collapsed
+only when it has the same canonical spell, the same case- and
+whitespace-insensitive caster identity, and the same complete valid reference
+sequence. Remaining entries retain their merged order.
+
+The optional normalized [NPC artifact](dnd-npc-artifacts.md) can ground a
+caster name. Its own references remain registry provenance and are never copied
+into `source_refs`.

+## Composition And Compatibility
 
-## Composition
+Notarius starts with the embedded base catalog, then applies overlay catalogs
+in ascending catalog-ID order. A new canonical spell name adds a recognition
+entry. If an overlay names an existing canonical spell, it augments that spell
+with aliases while retaining the established display spelling.
 
-The resolver always starts with the embedded D&D 5e 2014 SRD catalog. Overlay
-catalogs are sorted by `id` before composition, so the input order does not
-affect the result. A new canonical name adds a recognition entry. A canonical
-name matching an existing canonical name augments that spell and keeps the
-established canonical display spelling. Repeated aliases for the same spell
-are idempotent.
+Repeated aliases for the same spell are accepted. A canonical-name, canonical-

+# Published Evidence Context
+
+This contract defines the optional `source/evidence-context` artifact emitted
+by the production JSON output. Its configuration is owned by
+[Configuration](../config.md#module-bindings-and-validators); its logical-file
+discovery is owned by [Published JSON Output](json-output.md).
+
+## Identity And Discovery
+
+When enabled, the JSON bundle contains `evidence-context.json` and an
+`index.json` `evidence_context` descriptor with the same six fields as other
+pipeline-wide artifact descriptors.
+
+| Property | Value |
+| --- | --- |
+| Artifact kind | `source/evidence-context` |
+| Media type | `application/json` |
+| Schema ID | `notarius.source.evidence_context` |
+| Schema name | `notarius_source_evidence_context_v1` |
+| Schema version | `v1` |
+| Logical file | `evidence-context.json` |
+
+Consumers must discover the file from the descriptor, verify all six descriptor
+fields, and decode only a supported schema version. The descriptor is optional:
+its absence means evidence publication was not enabled for that bundle.
+
+## Payload
+
+The v1 payload is a JSON object with required `source_id`, `source_digest`,
+`window_units`, `selected_lanes`, and `contexts` fields. `selected_lanes` and
+`contexts` are always arrays; an enabled configuration with no accepted direct
+evidence publishes `contexts: []`.
+
+```json
+{
+  "source_id": "session-alpha",
+  "source_digest": "sha256:0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef",
+  "window_units": 1,
+  "selected_lanes": ["npcs", "spells"],
+  "contexts": [
+    {
+      "context_ref": {
+        "source_id": "session-alpha",
+        "start_unit_id": 10,
+        "end_unit_id": 20

+            "start_unit_id": 10,
+            "end_unit_id": 10
+          }
+        }
+      ],
+      "units": [
+        {
+          "id": 10,
+          "kind": "transcript_segment",
+          "text": "Aria casts Cure Wounds.",
+          "ref": {
+            "source_id": "session-alpha",
+            "start_unit_id": 10,
+            "end_unit_id": 10
+          }
+        },
+        {
+          "id": 20,
+          "kind": "transcript_segment",
+          "text": "The party regroups.",
+          "ref": {
+            "source_id": "session-alpha",
+            "start_unit_id": 20,
+            "end_unit_id": 20
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+Each context requires a `context_ref` object and `evidence_refs` and `units`
+arrays. `context_ref` identifies the first and last included unit. Each
+evidence entry contains a selected `lane_id` and an original `source_ref`. A
+unit uses the existing source-unit shape: required `id`, `kind`, `text`, and
+self `ref`, plus optional JSON-object `metadata`. Fixed payload objects reject
+unknown fields; unit metadata may contain application-defined JSON values.
+
+## Citations And Context
+
+`evidence_refs` are the authoritative citations. They identify the direct
+references emitted by accepted normalized artifacts. `context_ref` and the
+units collection include those cited units plus nearby source units selected by
+the configured window. They are explanatory context, not widened citations.
+
+Only accepted outputs from the configured lane allowlist contribute. Rejected,
+failed, absent, and lane-filtered outputs do not contribute. The artifact never
+contains raw input bytes, prompts, model responses, auxiliary reference
+content, credentials, or filesystem paths.
+
+## Ordering And Compatibility
+
+The selected lane allowlist is lexical. Contexts and units are in source
+document position order, not numeric unit-ID order. Direct evidence entries
+are deterministically ordered by lane and source reference. Overlapping or
+contiguous windows merge, and each source unit appears at most once in the
+resulting contexts.
+
+The artifact is additive to the JSON bundle and is not a lane payload,
+normalized-output count, checkpoint, or generated reference. Consumers that
+do not need it must tolerate the absent optional descriptor. Consumers that do
+use it should preserve the artifact and its schema identity with the run
+provenance, and should treat its source text and metadata as sensitive durable
+content.

-  ],
+  "output_files": [],

   "warnings_file": "warnings.json"
 }
 ```
 
-`output_files` is sorted by lane ID. Output file names are produced by
-sanitizing the lane ID:
+| Field | Required | Meaning |
+| --- | --- | --- |
+| `manifest_file` | Yes | Always `manifest.json`. |
+| `output_files` | Yes | Lane descriptors sorted by `lane_id`. |
+| `rejected_file` | Yes | Always `rejected.json`. |
+| `warnings_file` | Yes | Always `warnings.json`. |
+| `chunk_map` | No | Descriptor for the pipeline-wide `chunk-map.json`; never a lane descriptor. |
+| `evidence_context` | No | Descriptor for the pipeline-wide `evidence-context.json`; never a lane descriptor. |
 
-- characters outside `A-Z`, `a-z`, `0-9`, `.`, `_`, and `-` become `_`;
-- repeated `..` sequences are replaced;
-- leading and trailing `.`, `_`, and `-` are trimmed;
-- empty sanitized names are rejected;
-- two lanes that sanitize to the same output file are rejected.
+Each lane descriptor has required `lane_id` and `file`. It may also include
+`media_type`, `module_key`, `schema_id`, `schema_name`, and `schema_version`
+when supplied by the normalized artifact. Each pipeline-wide artifact
+descriptor (`chunk_map` or `evidence_context`) contains `artifact_kind`,
+`file`, `media_type`, `schema_id`, `schema_name`, and `schema_version`. Their
+payloads are defined by the [Accepted Chunk Map contract](chunk-map.md) and
+[Published Evidence Context](evidence-context.md), respectively.
 
-`manifest_file`, `rejected_file`, and `warnings_file` contain the fixed paths
-shown above. Each `output_files` entry requires `lane_id` and `file`. It also
-contains the normalized payload `media_type`, normalizer `module_key`, and
-response `schema_id`, `schema_name`, and `schema_version` when those values are
-available.
+The lane path is derived from its lane ID. Characters outside letters, digits,
+periods, underscores, and hyphens become underscores; `..` sequences are
+neutralized; leading and trailing periods and underscores are removed. A lane
+that produces an empty name, or two lanes that produce the same path, makes
+output encoding fail.
+
+## Lane Payloads
+
+Each `lanes/<safe-lane-id>.json` file is the codec-owned normalized JSON for
+that lane. Consumers should use the index descriptor’s schema identity rather
+than infer a lane schema from its name. The current D&D payload contracts are
+[spells](dnd-spell-artifacts.md), [NPCs](dnd-npc-artifacts.md),
+[NPC interactions](dnd-npc-interaction-artifacts.md),
+[combat turns](dnd-combat-turn-artifacts.md),
+[item events](dnd-item-event-artifacts.md), and
+[scene descriptions](dnd-scene-description-artifacts.md).
 
 ## `manifest.json`
 
-`manifest.json` contains a run manifest. This abridged example shows its core
-structure:
+`manifest.json` is published provenance, not a copy of lane payloads or a
+checkpoint store. Fields without a value may be omitted. Its top-level fields
+group into the following externally observable summaries:

+| Group | Fields |
+| --- | --- |
+| Run identity and result | `run_id`, `pipeline_id`, `pipeline_digest`, `schema_version`, `validation_status`, `started_at`, `completed_at` |
+| Resolved components | `input_module`, `chunker`, `extractors`, `merger`, `normalizer`, `output_encoder`, `artifact_lanes`, `validator_chains`, `module_metadata` |
+| Source and references | `source_digests`, `references` |
+| Published result summaries | `normalized_outputs`, `rejected_outputs` |
+| Execution summaries | `chunk_plan`, `checkpoint_decisions`, `llm_profiles`, `metadata` |
 
-Fields with empty values may be omitted by JSON encoding.
+`references` records provenance such as the target, slot, origin, digest,
+media type, size, and generated-artifact identity. It does not contain
+reference content. `normalized_outputs` and `rejected_outputs` likewise
+summarize results without embedding lane payload bytes. A chunk-plan summary is
+provenance for the plan used by this run; cache records, debug artifacts, and
+other operational state are not published as bundle files.
 
-The manifest fields are:
+Each `llm_profiles` entry identifies effective, non-secret LLM execution
+provenance:
 
-- `run_id`, `pipeline_id`, and `pipeline_digest`: run and resolved-pipeline
-  identity;
-- `input_module`, `chunker`, `extractors`, `merger`, `normalizer`, and
-  `output_encoder`: resolved module keys;
-- `chunk_plan`: payload-free provenance for the effective chunk plan. `mode`
-  is the effective cache mode; `action` is `reused`, `generated`,
-  `refreshed`, or `bypassed` when a plan was materialized. `requested_module`
-  is the current pipeline chunker, while `producer_input_module`,
-  `producer_module`, `producer_llm_profile`, `producer_references`,
-  `producer_metadata`, `source_digest`, `plan_digest`, `plan_schema_version`,
-  and `created_at` describe the stored or generated producer when available.
-  A cached plan can therefore identify a producer different from the requested
-  module. This object never embeds ranges, units, annotations, prompts,
-  responses, or reference content;
-- `module_metadata` and `artifact_lanes`: module and per-lane provenance,
-  including prompt and response-schema provenance when provided;
-- `validator_chains`: resolved validation points and validators;
-- `source_digests` and `references`: source and reference provenance;
-- `normalized_outputs` and `rejected_outputs`: payload-free result summaries;
-- `llm_profiles`: selected profile IDs and provider or model names when
-  available;
-- `metadata`: the effective prompt `session_id`;
-- `validation_status`: `approved` or `rejected`;
-- `started_at` and `completed_at`: UTC run timestamps.
+| Field | Required | Meaning |
+| --- | --- | --- |
+| `id` | Yes | Selected PromptKit profile identifier. |
+| `provider` | No | Notarius adapter provider identifier. |
+| `model` | No | Effective provider model identifier. |
+| `backend_id` | No | Effective PromptKit backend registration identifier. Endpoint-only profiles omit it. |
+| `reasoning_effort` | No | Effective opaque provider reasoning setting. An empty or explicitly cleared setting is omitted. |
 
-`source_digests` contains source document digests only. Bound references are
-recorded separately under `references`, which contains provenance only: target
-stage, lane ID when present, slot name, origin type and URI, digest, media
-type, byte size, and binding source. Reference content is not written to
-durable output.
+These values describe observed execution; they are not a backend-registration
+interface. Entries that differ by backend or effective reasoning remain
+distinct even when their profile, provider, and model are otherwise equal.
 
-Reference `stage` is `chunk`, `extract`, `merge`, or `normalize`. `lane_id` is
-omitted for chunk references and present for extract, merge, and normalize
-references.
+## Rejections And Warnings
 
-`validation_status` is `approved` when no outputs were rejected and `rejected`
-when one or more outputs were rejected.
+`rejected.json` is always an object with a `rejected` array. Each entry has
+required `stage` and `message`; `step_id`, `lane_id`, `module_key`, `chunk_id`,
+`chunk_index`, `validator_name`, `reason_code`, `attempt_count`, and
+`diagnostic_artifact_path` are present only when applicable.
 
-Producer warnings and the current run's chunk-validation warnings remain in
-`warnings.json`. The manifest records only provenance and decision summaries;
-empty producer-only values are omitted for compatibility with existing readers.
+`warnings.json` is always an object with a `warnings` array. Each warning has
+`reason_code` and `message`; `scope` is optional. Both arrays are empty when
+there is nothing to report.
 
-`validator_chains` records the resolved validator chain for each validation
-point. Entries include stage, lane ID when applicable, module key, and validators
-with key and execution class. Empty chains are recorded with an empty
-`validators` array, including chains resolved from explicit empty config
-overrides.
+## Compatibility
 
-`normalized_outputs` summarizes each normalized lane output without embedding
-payload bytes. Entries include lane ID, normalizer module key, source ID, media
-type, and response schema provenance where available.
-
-`rejected_outputs` summarizes rejected module outputs without embedding raw
-payload bytes. Entries include stage, lane, module, chunk, validator or reason,
-message, attempt count, and optional diagnostic artifact path.
-
-## Output Payload Files
-
-Each normalized serialized artifact is written to
-`lanes/<sanitized-lane-id>.json`. The JSON output encoder is domain-neutral and
-accepts only artifacts whose codec media type is `application/json`. The file
-contains the codec-owned JSON bytes pretty-printed.
-
-The schema of each lane payload is owned by that artifact contract. For the
-current D&D lanes, see [D&D Spell Artifact](dnd-spell-artifacts.md),
-[D&D NPC Artifact](dnd-npc-artifacts.md), and
-[D&D Combat-Turn Artifact](dnd-combat-turn-artifacts.md).
-
-## `rejected.json`
-
-Shape:
-
-```json
-{
-  "rejected": []
-}
-```
-
-When output validation rejects an output, each entry contains `stage` and
-`message`. It includes `lane_id`, `module_key`, `chunk_id`, `chunk_index`,
-`validator_name`, `reason_code`, `attempt_count`, and
-`diagnostic_artifact_path` when applicable.
-
-## `warnings.json`
-
-Shape:
-
-```json
-{
-  "warnings": [
-    {
-      "scope": "extract",
-      "reason_code": "example",
-      "message": "human-readable warning"
-    }
-  ]
-}
-```
-
-`warnings` is an empty array when no warnings are reported.
-Each warning requires `reason_code` and `message`; `scope` is omitted when it is
-empty.
+The index is the authoritative map from a logical lane to its published
+payload. Consumers must tolerate omitted optional manifest and descriptor
+fields, and should rely on the linked artifact contract for each lane’s JSON
+shape. This contract describes the published logical bundle only; it does not
+promise a filesystem layout or expose internal state formats.

+# PromptKit Integration
+
+Notarius pins
+[`gitea.maximumdirect.net/eric/promptkit` v0.5.0](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0)
+as its in-process prompt engine. The upstream
+[Go package consumer guide](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0/docs/consumers/pkg-promptkit.md)
+owns the public engine API, and the upstream
+[format reference](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0/docs/formats.md)
+owns prompt, profile, and schema file contracts.
+
+## Supported Boundary
+
+Notarius relies on the root `promptkit` package to:
+
+- construct an `Engine` with filesystem-backed prompt, schema, and optional
+  operator and application-fallback profile sources;
+- prepare one frozen execution from a `RunRequest` with named inline artifacts,
+  variables, a direct session ID, prompt identity, and profile selection, then
+  record credential-redacted details and run that exact execution;
+- return rendered debug material, validated structured output, selected
+  profile, backend, effective model metadata, and token usage;
+- register the optional conventional `local` backend through `BackendLocal`,
+  `LocalBackend`, and `WithBackend`;
+- distinguish structured-output validation failure from execution failure; and
+- identify a missing explicit profile through `ErrProfileNotFound` and backend
+  admission exhaustion through `ErrCapacityExceeded`.
+
+The pinned
+[`BackendLocal`, `LocalBackend`, and `WithBackend` API](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0/backends.go)
+owns the registration and backend-capacity contract.
+
+For one completion, the adapter calls `PrepareExecution`, takes a
+caller-owned `Details` snapshot, and calls `RunPrepared` for that same opaque
+prepared execution. It defers `Discard` for every unexecuted handle. Explicit
+profile preflight uses `Engine.InspectProfile`; it does not prepare a synthetic
+prompt. PromptKit's prepared handle, inspection result, and capacity-error
+types stay inside the Notarius LLM adapter.
+
+When a PromptKit profile and runtime override leave `temperature`, `max_tokens`,
+or `top_p` unset, Notarius leaves that control unset as well. Compatible
+providers therefore apply their own defaults; an operator that requires a
+specific sampling value must select it explicitly in the profile or runtime
+override.
+
+Notarius does not use PromptKit's optional `ArtifactReader`. It materializes
+source and reference content itself and supplies owned inline artifacts at the
+adapter boundary. It also retains responsibility for pipeline retries,
+scheduling, debug persistence, redaction, profile provenance, and conversion
+from private model responses into durable domain artifacts.
+
+Notarius sends its trimmed run session through PromptKit's direct session
+field, which is authoritative for provider session behavior. It also retains
+the same value as the `session_id` prompt variable for maintained prompt
+compatibility. Session IDs are stable, non-secret correlation identifiers and
+may be exposed to providers and provider observability.
+
+Notarius records PromptKit's selected backend ID and effective reasoning
+setting as optional run-manifest provenance. Endpoint-only profiles have no
+backend ID. Debug prompt material also retains the selected backend ID and
+PromptKit's stable lower-case `effective_model_params` JSON, which may include
+`backend_id`. Notarius production configuration exposes one optional
+conventional `local` registration. It does not expose a general user-defined
+PromptKit backend registry. Endpoint-only profiles remain supported unchanged.
+
+Notarius retains its application-wide scheduled client around the PromptKit
+adapter. PromptKit may apply a narrower limit for the selected backend;
+endpoint-only profiles have no such backend limit. The adapter translates
+PromptKit capacity rejection into the provider-neutral Notarius
+`ErrLLMCapacityExceeded` contract. It may include the normalized selected
+backend ID in safe diagnostic context, without exposing PromptKit's capacity
+error type, and leaves retries to the calling pipeline stage.
+
+## Profile Sources And Compatibility
+
+Notarius gives PromptKit the configured operator profile source, registered
+application fallback profile assets, and optional backend registration through
+the same construction path for inspection and execution. PromptKit owns the
+resulting source precedence and strict profile parsing: a matching operator
+profile is a complete replacement for a fallback or built-in profile, while an
+invalid matching document fails instead of falling through. The operator
+configuration and deployment workflow are defined in
+[Configuration](../config.md#promptkit-profiles) and
+[Operations](../operations.md#promptkit-profile-deployment).
+
+Notarius supports this boundary against PromptKit v0.5.0. Its fallback source,
+prepared-execution, inspection, and typed capacity APIs are used as public
+upstream contracts; other PromptKit APIs or file-format behavior are not
+implicitly supported. A dependency upgrade requires reviewing the adapter,
+profile-source construction, and this compatibility statement against the
+pinned upstream documentation.
+
+## Notarius Ownership
+
+[LLM Runtime Internals](../internal/llm.md) describes how Notarius mounts
+module assets, maps its transport-neutral completion contract, prepares and
+executes requests, validates output, records provenance, captures debug
+material, redacts errors, and preserves timeout ownership.
+[D&D Module Internals](../internal/dnd.md) owns the embedded
+`dnd-extraction` fallback profile and the maintained D&D prompt defaults.
+[Configuration](../config.md#promptkit-profiles) defines how a Notarius
+configuration selects one PromptKit profile source and optionally registers
+the conventional local backend.
+
+PromptKit API or format changes outside this boundary are not implicitly
+supported. Updating the pinned version requires reviewing the adapter and
+profile/configuration contracts against the upstream documentation.

+paths. They identify the paths used by Notarius and do not resolve symlinks.
+`output_directory` is the run-specific bundle, not the configured output root.
+
+The receipt is a summary and discovery document. It does not contain lane
+descriptors, payloads, manifest data, rejections, warnings, or file contents.
+For the production JSON output, resolve `index_file` beneath
+`output_directory`, reject path escapes, and use the
+[Published JSON Output contract](json-output.md) to discover logical files and
+lane payloads.
+
+## Delivery And Compatibility
+
+Notarius writes the receipt only after the output bundle has been published and
+any requested debug terminal reporting has completed. Standard output is not
+transactional: a result-write failure returns a nonzero status and can leave
+partial bytes. Consumers must ignore standard output unless the process exits
+with status 0.
+
+Future versions may add optional fields to this schema. Consumers must tolerate
+unknown fields. An incompatible field or semantic change requires a new
+`schema_version` value.

-# Seriatim Transcript JSON
+# Seriatim Transcript Input
 
-This document is the external input contract consumed by the production
-Seriatim input adapter. Selectable input-adapter keys are cataloged in
-[Configuration](../config.md#implemented-production-modules).
+This document defines the JSON transcript accepted by the production Seriatim
+input adapter. It is a source input, not a durable lane artifact. Configure the
+input adapter through [Configuration](../config.md#production-module-keys).
 
-## Adapter
+## Contract Identity
 
-- Source format: `application/vnd.seriatim+json`
+| Property | Value |
+| --- | --- |
+| Consumer | Seriatim input adapter |
+| Media type | `application/vnd.seriatim+json` |
+| Source document kind | `transcript` |
+| Source-unit kind | `transcript_segment` |
 
 ## Accepted Shape
 
-The input must be one JSON object with top-level `metadata` and `segments`
-fields. This covers the maintained minimal fixture and Seriatim intermediate
-output that provides the same required segment fields.
+The input is one JSON object containing `metadata` and a non-empty `segments`
+array. This minimal document is valid:
 
-The maintained example is
-[examples/seriatim-minimal-transcript.json](../../examples/seriatim-minimal-transcript.json).
+```json
+{
+  "metadata": {"id": "session-alpha"},
+  "segments": [
+    {
+      "id": 1,
+      "start": 0,
+      "end": 4,
+      "speaker": "Aria",
+      "text": "Aria casts Cure Wounds."
+    }
+  ]
+}
+```
 
-Required top-level fields:
+The maintained two-segment input is
+[seriatim-minimal-transcript.json](../../examples/seriatim-minimal-transcript.json).
 
-- `metadata`: an object. Its entries are accepted as source metadata.
-- `segments`: a non-empty array of segment objects.
+| Field | Required | Meaning and constraints |
+| --- | --- | --- |
+| `metadata` | Yes | JSON object. Its entries become source metadata; no particular metadata key is otherwise required. |
+| `segments` | Yes | Non-empty array of segment objects, kept in input order. |
+| `segments[].id` | Yes | Positive canonical decimal integer, supplied as a JSON number or string. IDs must be unique. |
+| `segments[].start` | Yes | Finite, non-negative numeric value, supplied as a JSON number or string. |
+| `segments[].end` | Yes | Finite, non-negative numeric value that is not earlier than `start`. |
+| `segments[].speaker` | Yes | String that is non-empty after trimming. |
+| `segments[].text` | Yes | String that is non-empty after trimming. Its original text is retained. |
 
-Required segment fields:
+Additional top-level and segment fields are ignored. A missing required field,
+`null` in place of an object or array, malformed JSON, or more than one
+top-level JSON value is rejected.
 
-- `id`: a positive integer JSON number or canonical decimal string without
-  leading zeros or surrounding whitespace;
-- `start`: a finite, non-negative JSON number or numeric string;
-- `end`: a finite, non-negative JSON number or numeric string that is not less
-  than `start`;
-- `speaker`: a non-empty string;
-- `text`: a non-empty string.
+## Source Identity And References
 
-Other top-level and segment fields, such as `categories`, are ignored.
+The adapter chooses the source ID in this order:
 
-Multiple top-level JSON values are rejected.
+1. a non-empty source ID supplied by the calling request;
+2. non-empty string `metadata.id`;
+3. non-empty string `metadata.source_id`;
+4. `seriatim:` followed by the first 16 hexadecimal characters of the raw
+   input’s SHA-256 digest.
 
-## Validation
+Each accepted segment becomes one source unit whose unit ID is `segments[].id`.
+Its self-reference uses the derived source ID and the same segment ID for both
+range endpoints. Artifact contracts use those segment IDs when they cite
+transcript evidence.
 
-The adapter rejects empty input, malformed JSON, multiple top-level JSON values,
-non-object segment values, duplicate segment IDs, and any violation of the
-shape or field constraints above.
+## Compatibility
 
-Segment text is preserved as provided, but it must not be empty after trimming.
-
-## Derived Identity
-
-Notarius identifies the parsed source in this order:
-
-1. `metadata.id`, when it is a non-empty string after trimming;
-2. `metadata.source_id`, when it is a non-empty string after trimming;
-3. `seriatim:<first-16-hex-chars-of-raw-sha256>`.
-
-The exact raw input SHA-256 remains the basis of the fallback source ID. The
-source digest recorded in output provenance is instead the SHA-256 of the
-canonical generic source document, excluding the digest field itself. It covers
-the derived source identity, document kind and format, ordered units and their
-self-references, and accepted metadata. Segment IDs become the unit IDs used by
-artifact source references; each produced unit carries a self-reference whose
-source ID is the derived document ID and whose start and end IDs both equal the
-segment ID.
-
-## Compatibility Limit
-
-This contract covers only Seriatim transcript JSON with the top-level
-`metadata` object and `segments` array described here. Broader Seriatim output
-schemas are compatible only when they provide these required fields with the
-accepted types.
+This adapter accepts only the shape described here. A broader Seriatim export
+is usable only when it supplies this object, metadata, and segment shape with
+the stated types and constraints. Unknown additional fields do not add
+Notarius behavior.

+# CLI Internals
+
+This document describes **internal/cli**, Notarius's production composition
+root. The [CLI reference](../cli.md) owns command syntax and exit statuses;
+[Configuration](../config.md) owns configuration values; and
+[Operations](../operations.md) owns filesystem layout, recovery, and operator
+procedures.
+
+## Inputs, Outputs, And Boundaries
+
+The CLI accepts process arguments, standard streams, and injectable options
+used by tests and embedding code. It writes command results to the supplied
+streams and returns a process exit status. For a run, it also creates the
+production catalog and runtime collaborators, hands a prepared pipeline and
+source bytes to the framework, and places the logical files returned by the
+runner.
+
+It is the only boundary allowed to compose concrete registries, LLM clients,
+cache/checkpoint collaborators, debug recorders, and physical output paths.
+Pipeline modules receive interfaces and request data rather than CLI streams or
+filesystem roots. The [Architecture](../policy/architecture.md) defines this
+composition-root boundary; [Pipeline Internals](pipeline.md) owns resolution,
+preparation, and runner mechanics after their inputs are supplied.
+
+## Dispatch And Configuration Handoff
+
+The root dispatcher handles help, configuration validation, pipeline listing,
+and a pipeline run. It normalizes injectable options before dispatch so that a
+missing production dependency fails as a command error rather than reaching
+execution.
+
+Commands that need configuration use one shared loader. The CLI discovers the
+file, parses it through **internal/core/config**, starts from defaults, applies
+the file and supported environment overrides, and then validates it for the
+command. The configured discovery and precedence contract is in
+[Configuration](../config.md), while the loading and resolution mechanics are
+in [Configuration Internals](configuration.md).
+
+Configuration validation without a selected pipeline checks structural
+configuration only. Validation with a selected pipeline also builds the
+effective catalog, resolves the pipeline, and verifies every explicit effective
+PromptKit profile. Selected LLM-backed input, chunk, lane, output, and validator
+profiles are inspected
+against the configured PromptKit source and backend registrations without
+loading a prompt or performing generation, so an unknown or invalid profile
+fails before pipeline preparation. Credential availability remains an
+execution-time concern. Pipeline listing validates configuration before
+returning normalized, sorted identifiers.
+
+## Production Composition
+
+The production composition helper allocates every framework registry and the
+prompt-asset registry, then registers the generic, Seriatim, and D&D module
+families in that order. The resulting registries provide both the module
+catalog used for resolution and the concrete constructors used for preparation.
+Tests may provide a catalog or registries instead; production code must not
+silently merge an injected partial catalog with production registrations.
+
+The production LLM factory builds one PromptKit-backed client from the resolved
+**promptkit.profile_dir** or **promptkit.profile_file** source, attaches the
+profile-provenance recorder, creates one scheduler from the effective global
+LLM limit, and wraps the client before it reaches modules. Registration and LLM
+construction errors are returned before a pipeline is prepared. Configuration
+field definitions remain in [Configuration](../config.md#promptkit-profiles);
+the D&D registrar's fallback profile assets and the adapter mechanics remain in
+[LLM Runtime](llm.md).
+
+The factory also accepts `LLMRuntimeOverrides`, whose reasoning pointer
+preserves inherit, replace, and clear states across the composition boundary.
+Run orchestration constructs this value from the mutually exclusive
+`--reasoning-effort` and `--clear-reasoning-effort` controls. Absence preserves
+a nil pointer, replacement is trimmed, and clear uses a non-nil empty string.
+The same override reaches the one shared production client, checkpoint
+identity, and debug invocation metadata. Persistent reasoning configuration
+remains owned by PromptKit profiles; Notarius configuration has no reasoning
+field.
+
+## Run Orchestration
+
+After parsing and validating a run invocation, the CLI performs this ordered
+handoff:
+
+1. load and validate configuration, then apply command-level operational
+   overrides;
+2. create and validate a safe run identity, then allocate a debug bundle only
+   when requested;
+3. build the effective catalog, resolve requested reference changes, resolve
+   the effective pipeline, and inspect its explicit effective PromptKit
+   profiles;
+4. materialize external or generated references and record redacted invocation
+   and resolution provenance when debug capture is enabled;
+5. construct registries, the scheduled LLM client, prepared modules, and the
+   requested cache/checkpoint collaborators;
+6. read the source input and invoke the framework runner; and
+7. write the runner's logical output files only after a successful run, then
+   complete the command report and user-facing result.
+
+Preparation happens before source parsing, so module construction and
+dependency failures cannot begin stage execution. The CLI also preserves the
+framework's result and warning information when it writes summaries and the
+final command result. Detailed state lifecycle, resume handling, and physical
+path confinement are maintained in [Run State Internals](state.md) and
+[Operations](../operations.md).
+
+For `run --json`, the CLI constructs and encodes its private run-result receipt
+after a successful runner result is available, before it publishes logical
+output files. It writes the prepared receipt to standard output only after
+output publication and requested debug terminalization succeed. A receipt-write
+failure exits with runtime status 1 and may leave partial standard-output bytes,
+but the already-published output bundle remains complete and requested debug
+reporting remains successfully terminalized. The CLI reports a bounded
+command-owned error and does not repeat terminal reporting. The receipt remains
+a CLI reporting concern rather than a framework or output-module responsibility;
+its public contract is the
+[run-result receipt](../integrations/run-result.md).
+
+## Failure Mapping And Terminal Reporting
+
+Argument, flag, and invocation-combination failures are reported to standard
+error before runtime composition and use the syntax error class. Once an
+invocation is syntactically valid, configuration loading and validation,
+resolution, registration, profile checks, reference materialization, module
+construction, input reads, runner failures, output publication, and requested
+debug handling use the runtime failure class. The public status numbers and
+stream contract are defined in the [CLI reference](../cli.md#output-streams-and-exit-statuses).
+
+When debug capture has been allocated, one command-state value records the
+known run result. Guarded terminalization writes a success report once, or
+attempts a failure report and error record once. A persistence failure is
+reported in addition to the original failure and never replaces it. If a debug
+path exists, failure output includes that path so the retained diagnostic data
+is discoverable.
+
+## Invariants To Preserve
+
+- Only the CLI composes production implementations and physical runtime roots.
+- Configuration and resolved composition failures occur before module
+  preparation or source parsing.
+- A runner's logical files are published only after a successful run.
+- Production registries and a caller-supplied catalog or registries are
+  alternative composition sources, not an implicit mixture.
+- A requested debug bundle has one terminal report attempt; its persistence
+  errors supplement rather than obscure the primary command error.

+# Configuration Internals
+
+This document describes the maintainer-facing configuration boundary in
+**internal/core/config**. The [Configuration](../config.md) reference owns the
+file format, fields, defaults, precedence contract, and selectable keys. The
+[CLI reference](../cli.md) owns command syntax; this document does not redefine
+either interface.
+
+## Boundary
+
+The configuration package turns a selected YAML file and supported environment
+values into a validated, independently owned configuration. It then resolves a
+requested pipeline against a module catalog before the framework prepares or
+runs anything.
+
+| Boundary | Inputs | Outputs | Does not own |
+| --- | --- | --- | --- |
+| Loading | Selected file path and environment lookup | Parsed file model and a populated **Config** | Choosing the file path or reporting a command result. |
+| Validation | **Config** | Structural configuration errors with pipeline, lane, or binding context | Module availability, capabilities, or construction. |
+| Resolution | Valid **Config**, selected pipeline and lanes, runtime reference changes, LLM override, and module catalog | **EffectiveConfig** with a **ResolvedPipeline** | Materializing reference bytes, preparing modules, execution, or filesystem state. |
+| Summary | **Config** or **EffectiveConfig** | Detached redacted payload suitable for debug summaries | Redacting arbitrary process state or provider traffic. |
+
+The CLI discovers a configuration file, invokes this package, and supplies the
+result to the framework. Configuration never reads an input file, constructs a
+module, or creates output, cache, or debug paths. Those responsibilities remain
+at their respective [CLI](cli.md), [pipeline](pipeline.md), and
+[run-state](state.md) boundaries.
+
+## Loading And Validation
+
+The CLI loads configuration in this order:
+
+1. parse the selected YAML file strictly into the file model;
+2. start from **Default**;
+3. apply the file model; and
+4. apply the supported environment overrides.
+
+This establishes the public precedence order without giving environment input a
+second file schema. Loading and application reject malformed YAML, unsupported
+file versions, unknown fields, invalid values, and identifiers that are empty
+or collide after whitespace normalization. The file application also makes the
+effective extraction-worker default follow the effective LLM limit. A present
+PromptKit local-backend object requires and trims its endpoint, defaults its
+omitted concurrency limit to zero, and is copied so the parsed file model
+cannot alias the populated **Config**. A pipeline `llm_profile` is
+presence-aware: omission remains empty, while a present blank value is
+rejected and a non-empty file value is trimmed before it reaches **Config**.
+
+**Config.Validate** checks configuration-only invariants before resolution. It
+rejects incompatible profile sources, invalid state-surface values, unsupported
+concurrency settings, malformed bindings and references, invalid retries, and
+invalid pipeline, step, or lane structure. PromptKit local-backend validation
+accepts only an absolute HTTP or HTTPS endpoint with a host and no user
+information, query, or fragment, and rejects a negative local concurrency
+limit. Its errors retain the closest known pipeline, lane, and binding context.
+It deliberately does not require modules to be registered: that requires a
+catalog and belongs to resolution.
+
+The exact user-selectable values and validation rules are defined in
+[Configuration](../config.md). Keep additions to the file model, an
+environment override, its validation, and that reference in the same change.
+
+## Effective Resolution
+
+**Config.Resolve** first recomputes derived concurrency defaults and validates
+the configuration. It normalizes the requested pipeline ID, copies the selected
+profile, and passes the non-empty command-level LLM profile override, requested
+lane selection, and reference changes to the framework resolver.
+
+After module and validator selection, the resolver applies the effective
+profile policy to LLM-backed bindings only: command override, binding profile,
+pipeline profile, then the prompt default. Deterministic bindings remain
+profile-free, and no second inheritance decision occurs during execution. The
+public field definitions and precedence are owned by
+[Configuration](../config.md#pipelines).
+
+The framework resolver supplies defaults, selects lanes, resolves validator
+chains, checks registered module and artifact compatibility, validates module
+options, and returns the fixed ordered pipeline shape. The resulting
+**EffectiveConfig** retains the selected ID, requested selection and reference
+changes, a clone of the input configuration, and the resolved pipeline.
+Callers may therefore retain or modify their input slices and maps without
+changing the resolved result, and later consumers cannot mutate the original
+configuration through the effective value. This ownership includes the nested
+PromptKit local-backend value.
+
+Resolution failures stop before module construction and source parsing. They
+include an error path for an unconfigured pipeline, missing module, missing
+capability, incompatible artifact variant, invalid option, invalid reference,
+or invalid lane selection. CLI code maps these valid-invocation failures to the
+runtime error class described in the [CLI reference](../cli.md#output-streams-and-exit-statuses).
+
+## Resolved Identity And Redaction
+
+The framework assigns the resolved pipeline a deterministic SHA-256 digest
+after defaults, lane selection, module bindings, reference bindings, validator
+chains, effective LLM profiles, and artifact schema identity have been
+resolved. The digest excludes
+its own stored value. It identifies resolved composition rather than raw YAML
+bytes, a debug payload, or all runtime state. The CLI records it as invocation
+provenance before execution; cache and checkpoint identity have additional
+owners in [Run State Internals](state.md).
+
+Configuration summaries must use **Redacted**, **RedactedSummaryPayload**, or
+**RedactedResolvedPipelinePayload**, never a direct configuration marshal.
+Those methods copy every binding and nested option container, replace values
+whose key is credential-shaped with **[REDACTED]**, and omit materialized
+reference content while retaining safe binding and reference provenance. The
+payload must not alias the source configuration or resolved pipeline.
+PromptKit's local endpoint and concurrency limit are preserved as non-secret
+configuration metadata in the independently owned summary; the object contains
+no credential value. This redaction is deliberately narrow: it protects
+configuration summaries and does not authorize recording arbitrary environment
+values or provider requests.
+
+## Invariants To Preserve
+
+- Defaults, YAML values, and environment values are applied in one direction;
+  later sources may override only their supported operational settings.
+- A configuration is structurally valid before it is resolved, and a resolved
+  pipeline is compatible with the supplied catalog before preparation begins.
+- Whitespace-normalized identifiers are unique wherever they identify a
+  pipeline, step, lane, worker, or reference slot.
+- Resolution and summary generation return detached data. Redaction must cover
+  every configured and resolved binding, including nested validator bindings.
+- The resolved digest changes when resolved composition changes and never
+  includes itself.
+
+## Focused Tests
+
+- **internal/core/config/file_config_contract_test.go** covers strict file
+  parsing, normalization, file application, and structural rejection.
+- **internal/core/config/env_contract_test.go** covers supported operational
+  overrides and their precedence.

+  invariants and contextual failures.

+  selections, overrides, resolution context, digest changes, and ownership.
+- **internal/core/config/redaction_test.go** covers recursive credential
+  redaction, reference-content exclusion, and non-aliasing payloads.
+
+Run **go test ./internal/core/config** after changing this boundary. Changes to
+the handoff or resolved-composition semantics also need the focused framework
+pipeline tests.

+# D&D Module Internals
+
+This guide records the conventions shared by the production D&D module family.
+It complements [Module Internals](modules.md), which owns generic registration
+and extension mechanics, and [Configuration](../config.md), which owns the
+selectable keys, bindings, reference syntax, and default validator chains.
+
+## Durable Artifact Contracts
+
+The six lanes have separate durable wire contracts. This guide deliberately
+does not repeat their JSON shapes or schemas.
+
+| Lane | Durable contract |
+| --- | --- |
+| Spells | [spell artifacts](../integrations/dnd-spell-artifacts.md) |
+| NPCs | [NPC artifacts](../integrations/dnd-npc-artifacts.md) |
+| Combat turns | [combat-turn artifacts](../integrations/dnd-combat-turn-artifacts.md) |
+| Item events | [item-event artifacts](../integrations/dnd-item-event-artifacts.md) |
+| NPC interactions | [NPC-interaction artifacts](../integrations/dnd-npc-interaction-artifacts.md) |
+| Scene descriptions | [scene-description artifacts](../integrations/dnd-scene-description-artifacts.md) |
+
+## Family Composition
+
+The D&D registrar registers the family’s artifact codecs, extractors, typed
+append-order mergers, normalizers, validators, prompt assets, fallback LLM
+profile asset, and default validator chains. Each extractor and normalizer has
+a stable module spec, explicit execution class, strict option decoding, and a
+typed builder. Scene chunking, every extractor, and NPC normalization are
+registered as `llm_backed`; the remaining current D&D mergers and normalizers
+are `deterministic`. The metadata is available to catalog inspection and
+resolved-pipeline debug data and determines which selected bindings inherit the
+pipeline profile. Configuration remains the canonical owner of the exact keys,
+profile precedence, and validator order.
+
+Private structured-LLM response schemas are deliberately minimal. They reject
+invalid JSON structure, missing required fields, incompatible types, and
+unknown fields, while preserving semantic candidates for deterministic
+validation. Do not promote a private response envelope into a durable schema;
+the contracts above define durable data.
+
+## Prompt Construction
+
+D&D extractors assemble prompts from an ordered manifest of shared and
+module-owned assets. Reuse the shared D&D system, evidence, identity,
+reference, and transcript assets instead of copying their text into individual
+modules. A manifest’s declared sequence, including cache-control placement, is
+part of the prompt behavior.
+
+Every maintained D&D LLM prompt selects `dnd-extraction` as its default
+profile. The D&D registrar embeds that fallback profile with the maintained
+OpenRouter model, timeout, and service-tier policy. An operator may provide a
+complete profile with the same ID through the configured PromptKit source; that
+definition replaces the fallback rather than merging with it. The fallback
+leaves reasoning and optional sampling controls unspecified. Deployment profile
+selection and the maintained operator example are documented in
+[Configuration](../config.md#promptkit-profiles).
+
+All extraction prompts share this four-message rendered prefix: the system
+message without cache control, the identity message without cache control, the
+campaign-reference message with ephemeral cache control, and the chunk
+transcript message with ephemeral cache control. This gives equivalent
+extraction requests the same reusable prefix through their source material.
+
+Extraction-evidence policy, generated NPC registries, spell catalogs, module
+tasks, and instructions follow the transcript because they are not universal
+across all extraction lanes. The final instructions message carries ephemeral
+cache control; evidence, registry, catalog, and task messages do not. Preserve
+this division when changing an extractor or its assets so prompt-cache behavior
+remains stable.
+
+The other D&D LLM prompts intentionally follow different patterns. Scene
+chunking has no sibling extraction lane with which to share its full transcript,
+so it renders campaign references before its task and instructions, then places
+the cacheable full transcript last. NPC normalization keeps its task and
+cacheable instructions before the candidate collection, followed by the
+cacheable transcript windows: candidates must be available before their
+supporting evidence is evaluated, and those windows are not a cross-lane
+prefix. Mounted assets and their declared message order determine the prompt
+fingerprint, so intentional prompt edits continue to invalidate stale
+checkpoints.
+
+All extractors use the shared prompt-input preparation rules. The current chunk
+is copied into transcript material; player, party, glossary, and compatible
+campaign references are context for disambiguation, not source evidence.
+Reference prompt material is canonically ordered before it is rendered, which
+keeps equivalent inputs stable across runs.
+
+## Evidence, Candidates, And Normalization
+
+The current transcript is the only durable evidence source. Extractors assign
+the current source identity, preserve candidate evidence ranges for validators,
+and canonically order or remove exact duplicate ranges without asking the
+model to repair semantic errors. Campaign context and generated artifacts may
+ground names or control routing, but they never establish evidence for a D&D
+result.
+
+Default chains keep responsibilities separate: structural validators assess the
+candidate, source-reference validators resolve cited ranges against the current
+source, durable-schema validation checks an approved representation, and
+relatedness validators report advisory evidence concerns. The configured order
+is documented in
+[Configuration](../config.md#production-validator-keys-and-default-chains).
+
+Normalizers are deterministic for spells, combat turns, item events, NPC
+interactions, and scene descriptions. They canonicalize display values and
+evidence, use source-document order for stable output, and issue bounded
+warnings for changes or collapsed duplicates. The NPC normalizer is the
+intentional exception: it first produces a deterministic candidate set, then
+uses a bounded structured-LLM proposal to reconcile identity groups. Invalid
+or unusable proposals retain the deterministic result and surface retry or
+fallback diagnostics; the model does not directly replace durable records.
+
+## Generated References And Grounding
+
+Normalized D&D artifacts can be handed to a later step through a generated
+reference binding. The framework verifies artifact compatibility and retains
+producer provenance; consumers resolve the handed-off artifact into an
+immutable, validated projection for each operation. External files are checked
+during preparation, while generated artifacts are resolved at the handoff.
+
+NPC registries are names-only grounding projections: they may canonicalize
+actors for spells and combat turns and are required for NPC interactions, but
+they do not supply evidence. Scene-description registries are eligibility-only
+projections: they retain the current chunk’s classification data, not scene
+prose or evidence, and exist to route combat extraction.
+
+## Lane-Specific Rules
+
+The following differences are intentional and should remain explicit when a
+shared helper changes.
+
+| Lane | Intentional behavior |
+| --- | --- |
+| Spells | May use a spell-catalog overlay and optional NPC grounding; the catalog validator supplies domain-specific semantic checks. |
+| NPCs | Does not consume an NPC registry. Its normalizer is the LLM-assisted reconciliation exception described above. |
+| Combat turns | Requires a scene-description artifact. It calls the LLM only for an exact `combat` classification; exact non-combat classifications return an accepted empty result, while missing or mismatched classifications return an empty result with a bounded warning. Optional NPC grounding never becomes evidence. |
+| Item events | Uses campaign context for disambiguation but has no NPC-registry or scene-description dependency. |
+| NPC interactions | Requires the normalized NPC registry at extraction and normalization, using it for canonical actor grounding only. |
+| Scene descriptions | Produces the classifications consumed by combat routing; it does not consume an NPC registry or provide evidence for combat artifacts. |
+
+The combat and scene-description contracts describe their exact handoff and
+empty-result behavior in more detail:
+[combat turns](../integrations/dnd-combat-turn-artifacts.md) and
+[scene descriptions](../integrations/dnd-scene-description-artifacts.md).
+
+## Focused Verification

+validator, prompt-asset manifest, and registry projection. Also test generated
+handoffs at the integration boundary and run the full D&D module suite:

 # LLM Runtime Internals
 
-`internal/framework/llm` implements Notarius's transport boundary for structured
-completion. It contains the Scriptorium adapter, concurrency scheduler,
-prompt/schema registries, selected-profile recording, and provider-error
-redaction.
+`internal/framework/llm` is Notarius’s provider-independent structured
+completion boundary. It adapts framework requests to PromptKit, bounds
+provider calls, assembles registered prompt and schema assets, records selected
+profiles, and redacts provider errors. The architectural boundary is defined in
+[Architecture](../policy/architecture.md#llm-boundary); profile sources,
+credentials, and concurrency settings belong in
+[Configuration](../config.md#promptkit-profiles) and
+[Configuration](../config.md#concurrency-output-cache-and-debug).
 
-Provider-neutral ownership rules are defined in
-[Architecture](../policy/architecture.md#llm-boundary). Profile sources,
-credentials, and concurrency settings are defined in
-[Configuration](../config.md).
+## Structured Completion Boundary
 
-## Structured Contract
+Modules and LLM-backed validators depend only on
+`contracts.StructuredLLMClient`. A completion request supplies a prompt ID and
+version, optional profile and session IDs, named input material, variables, and
+a caller-owned decode target. The successful response returns the validated raw
+structured bytes together with non-secret provider, model, profile, and token
+metadata.
 
-Modules and LLM-backed validators depend on
-`contracts.StructuredLLMClient.CompleteStructured`. A request identifies a
-prompt and optional profile/session, supplies named input materials and
-variables, and provides a caller-owned decoding target. A successful response
-contains the validated raw structured bytes plus non-secret provider, model,
-profile, and token metadata.
+The caller owns the domain behavior: it chooses the prompt, prepares inputs,
+selects the private response schema, and interprets the decoded result. The
+adapter does not own source evidence, artifact conversion, normalization, or
+durable schemas. Those responsibilities remain with the module and its
+[integration contract](../integrations/).
 
-The caller owns prompt selection, response-schema selection, and interpretation
-of the decoded result. `LLMInputMaterial` keeps source and reference bytes with
-their origin metadata so the adapter can pass named artifacts to Scriptorium
-without exposing Scriptorium types through stage contracts.
+`PromptKitClient` validates the request target and prompt identity, maps each
+named material to a PromptKit inline artifact while preserving its origin URI,
+maps the trimmed request session to PromptKit's direct per-run session field,
+retains the same value as the `session_id` prompt variable for maintained
+prompt compatibility, and forwards profile selection. It then creates one
+frozen prepared execution, captures its caller-owned credential-redacted
+details for debug material, and executes that exact snapshot through
+PromptKit's prepared-execution boundary. The direct field
+is authoritative for provider session behavior. A session ID is a stable,
+non-secret correlation identifier and may be exposed to providers and provider
+observability. The adapter returns PromptKit’s validated raw bytes rather than
+re-encoding the decoded target. An empty optional material is represented as
+one space so its named input is retained by PromptKit.
 
-## Production Construction
+Client construction may also receive a run-wide reasoning-effort override from
+the CLI factory boundary. The adapter copies the caller-owned pointer and
+creates a fresh PromptKit execution override for each request: a nil pointer
+inherits the selected profile, a non-empty value replaces it, and an empty
+value clears inherited reasoning. The CLI's mutually exclusive
+`--reasoning-effort` and `--clear-reasoning-effort` controls select those
+states. With neither flag, profile behavior remains unchanged. Because
+production constructs one shared client, the selected state applies uniformly
+to module calls, retries, and LLM-backed validators for the whole run.
 
-`internal/cli` constructs the production runtime by:
+An empty request profile lets the prompt select its configured default. Before a
+run begins, the CLI asks the adapter to inspect every explicit profile on the
+resolved selected LLM-backed bindings and validators, including inherited
+pipeline profiles. Inspection resolves the profile and its selected backend and
+target without loading a prompt, reading credentials, admitting capacity, or
+contacting a provider, so a missing or invalid explicit profile fails before
+stage execution while a valid `api_key_env` may remain unset. Calls record the
+profile actually selected by PromptKit. The recorder trims and deduplicates
+non-secret profile identity, provider, model, selected backend ID, and
+effective reasoning values for manifest use. Entries that differ in backend or
+reasoning remain distinct and deterministically ordered. Endpoint-only profiles
+retain an empty backend ID, which the published JSON omits. Successful
+completion responses and recorded profile manifests identify the adapter
+provider as `promptkit`.
 
-1. allocating the asset registry populated by the generic, Seriatim, and D&D
-   package-family registrars;
-2. creating a `ScriptoriumClient` from the effective profile source;
-3. attaching an `LLMProfileRecorder`;
-4. creating a scheduler from the effective concurrency limit;
-5. returning a `ScheduledClient` wrapper;
-6. decorating that shared client before preparation when debug recording is
-   enabled; and
-7. injecting that one shared client into complete pipeline preparation before
-   the source file is read or the runner is invoked.
+The CLI's profile-inspection engine and the production adapter use the same
+profile-source construction to apply the configured profile directory or file,
+the optional registered fallback profile assets, and the optional conventional
+`local` backend. Preflight therefore resolves the same profile sources and
+backend membership as runtime without performing generation. Fallback assets
+are mounted only when at least one source is registered. The production D&D
+registrar contributes its `dnd-extraction` fallback, and the maintained D&D
+prompts select that logical ID by default. PromptKit owns source precedence and
+profile parsing: an operator-provided matching profile takes precedence over a
+fallback profile without Notarius merging either document.
+When the registration is absent, a profile selecting `backend: local` fails
+inspection instead of falling back to a built-in or endpoint-only target.
 
-The D&D scene chunker and spell, NPC, and combat extractors retain this
-injected client and use it for every structured completion. Operation requests
-do not carry an LLM client.
+Before execution, the adapter also contributes a non-secret checkpoint
+fingerprint for the effective PromptKit profile source. It combines the
+identity of PromptKit's compiled-in profile catalog with a deterministic digest
+of every YAML profile in the configured profile directory, or of the configured
+profile file, and a deterministic digest of the flattened fallback profile
+assets. The fingerprint contains neither profile content nor source paths. It
+covers inherited pipeline profiles, explicit binding profiles, and
+prompt-selected defaults, so changing a model or other profile setting cannot
+reuse checkpoints created under the
+prior profile source. This cache identity is independent of durable
+profile provenance: run manifests continue to list only profiles actually
+observed during LLM calls. When the local backend is registered, a second
+fingerprint hashes its trimmed endpoint behind a stable marker. Changing that
+semantic execution target invalidates checkpoint reuse. The raw endpoint is not
+stored in checkpoint identity, and the local concurrency limit is excluded
+because it changes scheduling rather than execution semantics.
 
-The CLI separately gathers explicit profile IDs from resolved LLM-capable stage
-and validator bindings. It prepares a small internal check prompt for each ID so
-missing or invalid profiles fail before pipeline execution. The runtime profile
-override syntax and scope are defined in the
-[CLI reference](../cli.md#run); binding rules are defined in
-[Configuration](../config.md#module-bindings).
+## Shared Provider-Call Limit
 
-## Scriptorium Adapter
+Production construction creates one PromptKit client and wraps it in one
+scheduled client. The scheduler has a fixed, positive permit limit, serves
+queued calls in FIFO order, and removes a queued call when its context is
+cancelled. A granted permit is released exactly once on every completion path.
 
-`ScriptoriumClient` converts a Notarius request into a Scriptorium `RunRequest`.
-It validates the decoding target and prompt identity, maps named input materials
-to inline artifacts, forwards explicit profile and session context, delegates
-rendering/provider execution/structured validation, and unmarshals successful
-JSON into the caller target.
+The scheduled wrapper surrounds every `CompleteStructured` call, so concurrent
+lanes, pipeline retries, and LLM-backed validators share the same provider-call
+ceiling. This ceiling is independent of pipeline worker concurrency; changing
+worker counts cannot exceed the configured LLM limit. The configuration field
+and its effective default are owned by
+[Configuration](../config.md#concurrency-output-cache-and-debug).
 
-Empty optional input material is represented by a single space so Scriptorium
-retains the named input. The client returns Scriptorium's validated structured
-bytes rather than re-encoding the caller target, allowing modules to preserve
-the runtime result exactly.
-
-Selected profile, provider, model, and token metadata are mapped into the
-Notarius response. The recorder deduplicates profiles by identity and supplies
-manifest-safe profile summaries after actual calls; manifest population does
-not guess the selected prompt default in advance.
-
-Generated-output validation failures and provider failures are wrapped with
-prompt context. Error strings pass through bearer-token redaction before they
-cross the runtime boundary.
-
-## Scheduling
-
-`Scheduler` uses a bounded permit count and a FIFO waiter queue. Immediate
-acquisition increments the in-flight count; queued acquisition waits for a
-permit or context cancellation. Cancellation removes a queued waiter, while a
-cancelled waiter that has already received a permit releases it.
-
-`ScheduledClient` acquires a permit around each structured completion and
-defers release on every result path. The effective limit and default are
-configuration facts in [Configuration](../config.md#defaults).
-
-This provider-call ceiling is independent of the pipeline's extract worker
-limit. Concurrent lanes, retries, and validators all use the same scheduled
-client, so increasing framework workers cannot exceed `total_llm`. Pipeline
-dispatch and cancellation mechanics are documented in
-[Pipeline Internals](pipeline.md#execution-flow).
+PromptKit applies a second, independent admission limit when the selected
+profile names a limited backend. It sits beneath the Notarius scheduled client,
+so it may narrow but cannot expand the application-wide limit. Built-in
+OpenRouter profiles select PromptKit's reserved backend and its upstream
+capacity policy. A positive configured local-backend limit bounds active local
+generations inside PromptKit; zero leaves that backend unlimited there.
+Endpoint-only profiles do not select a PromptKit backend and remain limited
+only by the Notarius scheduler.
 
 ## Prompt And Schema Assets
 
-`AssetRegistry` combines caller-owned prompt filesystems under stable prefixes
-and rejects invalid or conflicting registrations. Production module packages
-register their own prompt and schema assets; generic framework code contains no
-D&D prompt content. `internal/framework/promptfs` provides the domain-neutral
-filesystem composition helper used to combine module-owned files with shared
-domain prompt fragments.
+An `AssetRegistry` collects prompt, schema, and optional fallback-profile
+filesystems from production module families. It flattens registered roots into
+the corresponding PromptKit filesystems and rejects invalid roots, unreadable
+assets, duplicate paths, and missing prompt or schema files during preparation.
+Fallback assets receive a safe content digest for checkpoint identity; raw
+paths and bytes are never included. The framework’s `promptfs` helper combines
+module-owned prompt files with reusable domain fragments without making the
+framework depend on D&D content.
 
-The D&D scene chunker and spell, NPC, and combat-turn extractors each declare an
-ordered prompt asset manifest. The manifest lists the package-owned YAML and
-Markdown files, then the exact shared fragments rendered by that prompt; the
-same ordered list drives both filesystem mounting and the prompt fingerprint.
-Unused shared assets are neither mounted nor fingerprinted. Universal
-extraction-evidence and output policy lives only in the shared extraction
-assets; package-owned prompt files retain artifact-specific rules. The scene
-prompt keeps its separate output rule because it does not render the
-extraction-evidence asset.
+Each LLM-backed module owns its prompt declaration, package-specific assets,
+and private response schema. Shared D&D wording is owned by the D&D shared
+asset package; the detailed D&D conventions are in
+[D&D Module Internals](dnd.md). The mounted prompt assets used by a module also
+determine its prompt fingerprint. Schema loaders validate JSON, attach identity
+and digest metadata, make defensive copies, and expose diagnostics without raw
+schema bytes.
 
-### D&D Extraction Prompt Ordering And Cache Boundaries
+Private response schemas validate a model transport envelope. They are not the
+durable artifact schema and should not be documented as an external wire
+contract. Durable formats and compatibility rules remain in the
+[integration contracts](../integrations/).
 
-D&D extraction prompts order messages from the most reusable content to the
-most variable content. New extraction lanes use these tiers in order:
+## Prompt Maintenance And Backend Caching
 
-1. universal shared content, including the system, extraction-evidence, and
-   in-world identity messages;
-2. stable campaign or run context shared across lanes, including campaign
-   references;
-3. stable subset- and lane-specific context and instructions, including an NPC
-   registry, catalog, task, or extraction instructions when applicable;
-4. the chunk transcript as the final user message.
+Prompt message order and shared asset bytes are runtime behavior. Backend cache
+reuse depends on identical preceding roles, rendered bytes, and cache-control
+metadata—not merely equivalent meaning. Keep reusable shared assets
+byte-identical and preserve each prompt’s declared ordering and cache controls
+when editing it.
 
-This ordering lets requests reuse the longest identical prefix before the
-per-chunk transcript changes. Cache reuse requires the preceding message
-sequence and content to be exactly identical; semantic similarity is not
-sufficient. Cache boundaries belong at the ends of reusable stable tiers,
-subject to the provider's cache-boundary limit. The shared identity and
-campaign-reference messages form the first two extraction boundaries. Spell
-and combat prompts add a boundary at the shared NPC registry. Each extraction
-prompt places its final boundary on its lane-specific instructions, immediately
-before the transcript. The transcript does not carry cache control because no
-reusable content follows it.
+For sibling prompts that can reuse the same source material, order universal
+shared context first, request source material next, and module-specific
+suffixes last. Put a cache boundary at a reusable prefix that is useful to the
+backend. Redundant intermediate cache boundaries do not extend that reusable
+prefix and add no value.
 
-Accordingly, the common prefix of all three extraction prompts is system,
-extraction evidence, identity, and campaign references. The NPC prompt then
-renders task, instructions, and transcript. Spell renders immediate resolution,
-NPC registry, catalog, task, instructions, and transcript. Combat renders
-immediate resolution, NPC registry, task, instructions, and transcript. The
-scene chunker is not an extraction lane: it retains its separate system,
-transcript, campaign-reference, task, and instruction order and marks its
-transcript and campaign-reference messages ephemeral.
+Prompt-family owners may choose a different sequence when their inputs and
+reuse pattern differ. The D&D family’s extraction, scene-chunking, and NPC
+normalization policies are maintained in [D&D Module Internals](dnd.md#prompt-construction).
+Do not add tests that enforce prompt prose; prompt tests should verify the
+meaningful input placement and cache controls of the prompt being changed.
 
-Shared wording belongs in the canonical assets under
-`internal/modules/dnd/shared`; extraction packages reference those assets in
-their manifests instead of copying similar text into package-local files.
-Package-local assets contain only lane-specific content. An extraction lane may
-depart from the tier order only when prompt-quality evidence or a provider
-constraint makes the exception necessary; document the exception and rationale
-here when it becomes implemented behavior.
+## Validation, Repair, And Retries
 
-Schema helpers load embedded JSON Schema with identity and digest metadata,
-return defensive copies, and expose a diagnostics map that omits schema bytes.
-The small framework registry contains only generic test schemas; production
-schemas remain package-owned.
+PromptKit performs prompt rendering, provider execution, and the prompt’s
+structured-output validation. The adapter reports an empty result, validation
+failure, empty structured body, or decode failure as
+`ErrInvalidStructuredOutput`, while retaining the returned raw bytes and debug
+material when they exist. Provider failures remain operational errors rather
+than output-validation failures.
 
-The spell, NPC, and combat extractors' package-owned prompts declare their
-structured JSON inputs and private response schemas. Each private response
-schema remains separate from its durable artifact codec schema; this work does
-not use shared schema fragments or schema generation. The combat private schema
-owns the transport envelope—required fields, JSON types, nullability, and
-unknown-field rejection—while its deterministic validators own semantic
-constraints such as enum membership, non-empty values and collections, and
-positive numbers. The spell extractor's prompt declares a required
-`application/json` `spell_catalog` input and an optional `application/json`
-`npcs` input. The extractor generates
-the catalog input from its prepared
-effective catalog as `{"spell_names":[...]}` using sorted canonical names only.
-The shared D&D prompt assets include a generic NPC grounding fragment directly
-after the campaign reference message for spell and combat prompts. When an NPC
-registry is bound, the
-domain registry boundary strictly decodes and identity-validates one durable
-artifact, re-encodes canonical JSON, and generates a semantic digest over
-those bytes. The unbound input is exactly `{"npcs":[]}`. Input digests cover
-the generated bytes; manifests record catalog identity and optional NPC
-registry digest/count rather than names, aliases, overlay bytes, registry
-paths, or source metadata. Combat prompt, response-schema, mapping,
-normalization, identity, and bound-registry fingerprints remain separate
-semantic inputs to checkpoint identity.
+When PromptKit rejects backend admission before generation, the adapter maps
+`promptkit.ErrCapacityExceeded` to
+`contracts.ErrLLMCapacityExceeded`, retaining prompt context and a redacted
+upstream diagnostic without exposing the PromptKit sentinel or capacity-error
+type as a framework contract. When supplied, the normalized selected backend
+ID appears only in that safe application-owned diagnostic context. A canceled
+caller context takes precedence. The adapter does not retry capacity failures;
+the pipeline's existing binding attempt policy sees the operational error and
+decides whether to rerun the complete operation.
 
-## Debug And Redaction Boundaries
+Prompt-declared repair is executed within PromptKit’s structured-output flow.
+The current production D&D prompt manifests set repair attempts to zero. That
+setting does not replace pipeline retry behavior: a binding’s configured retry
+count reruns its stage attempt after an error or rejection, and an exhausted
+rejection is a recorded output rather than a provider error. The pipeline owns
+attempt lifecycle, validation chains, and retry diagnostics; see
+[Pipeline Internals](pipeline.md#validation-retries-and-output) and the
+[binding reference](../config.md#module-bindings-and-validators).
 
-The pipeline may wrap the client with a debug recorder that captures prepared
-prompt/response material for an explicitly requested debug run. Debug summaries
-and manifests receive identities, hashes, usage, and selected profile summaries
-rather than prompt, source, reference, schema, or response content.
+## Timeout Ownership
 
-The Scriptorium error wrapper removes bearer credential values from surfaced
-provider errors; `RedactSecrets` and `ErrorWithSecretsRedacted` support known
-secret values elsewhere in the runtime. Config summaries use a separate
-clone-and-redact path in `internal/core/config`. These mechanisms implement the
-security invariant in
-[Architecture](../policy/architecture.md#state-output-and-safety); operator
-handling of debug data is defined in [Operations](../operations.md#debug).
+The caller context remains the outer cancellation authority. PromptKit applies
+a positive effective generation timeout as an inner request deadline; an
+explicit zero disables only that generation deadline. The HTTP client timeout
+is a separate transport-wide cap. Notarius forwards the caller context and
+does not install another timeout wrapper around PromptKit.
 
-## Failure Behavior
+The selected PromptKit profile owns generation settings. Notarius binding
+retries remain outside the adapter and repeat the complete module operation
+and validation chain. PromptKit does not add a provider retry loop.
+Operator-facing behavior is summarized in
+[Operations](../operations.md#operational-limits), and the pinned upstream
+contract is identified in
+[PromptKit Integration](../integrations/pkg-promptkit.md).
 
-- Invalid targets, missing prompt IDs, malformed structured output, and
-  Scriptorium failures return contextual errors to the calling module.
-- Scheduler construction rejects non-positive limits; acquisition respects
-  context cancellation.
-- Asset registration rejects invalid roots, missing content, and path conflicts.
-- Schema loading distinguishes missing assets, invalid JSON, and invalid
-  metadata.
-- Profile validation errors occur during CLI preparation when an explicit
-  selected ID cannot be prepared.
+## Observability And Redaction
 
-## Tests To Inspect
+When debug recording is enabled, the pipeline decorates the shared client. The
+wrapper records prepared prompt and response material, timing, selected profile
+and backend, effective model parameters, and call identifiers in the run’s
+debug bundle, including material available from a failed structured completion.
+Effective parameters use PromptKit's stable lower-case JSON field names and may
+include `backend_id`. For a successful completion, a debug-write failure is
+surfaced; when the completion already failed, its call error remains the
+result. Debug-bundle location, retention, and handling are operational concerns
+documented in [Operations](../operations.md#debug-bundles).

+Run manifests receive selected profile summaries, including optional effective
+backend and reasoning provenance, and component identities—not prompt, schema,
+source, reference, or response content. The published field semantics belong
+to the [JSON output contract](../integrations/json-output.md#manifestjson).
+Provider error text is wrapped with prompt context and bearer credentials are
+redacted before it crosses the runtime boundary. Known-secret redaction is
+available to other runtime collaborators; it does not make prompt or response
+contents safe for general logging.
+
+## Failure Boundaries
+
+- Construction fails for missing asset registries, mutually exclusive profile
+  sources, invalid asset registration, or a non-positive scheduler limit.
+- Preparation failures, unavailable explicit profiles, provider failures, and
+  context cancellation propagate to the calling stage with context.
+- Backend admission exhaustion is a provider-neutral operational error and is
+  not classified as invalid structured output or validator rejection.
+- Malformed or schema-invalid provider output is classified separately as
+  invalid structured output so the module or pipeline can apply its own retry
+  and rejection policy.
+- Domain semantic checks, evidence decisions, and deterministic normalization
+  run outside the provider adapter.
+
+## Focused Verification
+
+Read the LLM adapter, scheduler, asset registry, schema loader, and redaction
+tests when changing this boundary. Prompt changes also require the owning
+module’s asset tests, and retry or debug changes require focused pipeline or
+CLI coverage. The focused runtime and D&D checks are:

-# Module And Validator Internals
-
-Production module and validator implementations live under their domain-first
-trees in `internal/modules`.
-The selectable keys, configuration options, reference slots, and default
-validator chain are canonical in the
-[module](../config.md#implemented-production-modules) and
-[validator](../config.md#implemented-production-validators) catalogs in
-Configuration.
-
-## Extension Pattern
-
-A stage module package provides a stable key, constructor, contract
-implementation, `ModuleSpec`, `Register`, and focused behavior and registration
-tests. A validator package follows the same pattern with `ValidatorSpec` and the
-validator registry. Package-family registrars compose those leaf registrations
-into the production catalog and own family-level policy such as default
-validator chains and prompt asset collection.
-
-Production input, chunk, output, and D&D spell- and combat-extract packages
-register strict option decoders and run-local builders. Preparation decodes their options into
-implementation-owned values and injects dependencies plus the materialized
-reference set for the selected target. Each builder receives an isolated clone
-of that set; input and output builders receive no references. The spell and
-combat extractors are typed over the canonical D&D model. D&D validators, merge,
-and normalize use typed variants; JSON representation validators use serialized
-requests; and unconditional validators expose separate chunk and typed
-variants. The D&D production registrar registers the canonical typed spell,
-NPC, and combat implementations, including their kind-specific merge and
-normalize behavior.
-
-Prepared extractors, extract validators, and codecs may be reused concurrently
-by the run-wide extract pool. Production implementations are immutable after
-construction: they retain only typed options, immutable assets, or the shared
-concurrency-safe LLM client. Implementations that introduce mutable state must
-synchronize that state without creating a separate provider scheduler.
-
-Specs expose capability and execution metadata without constructing an
-implementation. Registry entries separately expose option validation and
-run-local construction. Chunk, extract, merge, and normalize modules that accept
-auxiliary material declare identical reference slots from both
-`ReferenceSlots()` and `ModuleSpec().ReferenceSlots`; registration tests enforce
-that agreement. Runtime delivery uses the corresponding stage request's
-`References` field.
-
-LLM-backed extensions own their prompt definitions and response schemas under
-package-local embedded assets. Shared filesystem composition belongs in
-`internal/framework/promptfs`; reusable D&D prompt fragments, reference
-declarations, prompt-input assembly, and source-unit/citation helpers belong in
-`internal/modules/dnd/shared`, which also owns bounded D&D diagnostics. The
-D&D scene chunker and spell, NPC, and combat-turn extractors use ordered
-package-local prompt manifests for both rendering and prompt fingerprinting, so
-only the shared fragments each prompt actually renders participate in either
-operation. Extraction prompts place stable shared and lane-specific context
-before the variable transcript and use shared assets for wording common across
-lanes. The canonical ordering and cache-boundary policy is documented in
-[LLM Runtime](llm.md#dd-extraction-prompt-ordering-and-cache-boundaries). Stage
-contracts expose only Notarius structured-completion types, not Scriptorium
-public types.
-
-The shared `ChunkPromptMaterial` helper owns common transcript material
-preparation for the spell, NPC, and combat-turn extractors. It clones supplied
-source metadata, falls back to the materialized chunk when content is absent,
-checks that content remains chunk-identical, and fills only the common default
-fields. Extractors retain their request validation and wrap helper errors with
-their module context.
-
-Reference material may inform a module or prompt but must not become source
-evidence. The resolver and materializer behavior is described in
-[Pipeline Internals](pipeline.md#reference-materialization).
-
-## Domain Reference Data
-
-### `internal/modules/dnd/spells/catalog`
-
-The spell catalog package owns the embedded, versioned D&D 5e 2014 SRD spell
-reference data. Its strict JSON asset contains one canonical record per spell,
-including spell level and all applicable class memberships. `LoadSRD5E2014`
-validates catalog identity, provenance metadata, ordering, uniqueness, levels,
-classes, aliases, and lookup-key collisions before exposing immutable copies.
-
-Lookup is case-insensitive and normalizes whitespace and common apostrophe
-variants while preserving source punctuation in canonical display names. The
-catalog contains 319 unique spells and 779 class memberships. Source and
-license details live beside the asset in `SOURCES.md`. This domain-owned data is
-separate from `internal/modules/dnd/shared`, which is reserved for reusable
-prompt and source-reference machinery.
-
-`ResolveEffectiveCatalog` builds the immutable recognition view used by the
-spell extractor and catalog validator. It starts with the embedded SRD catalog
-and optionally applies one strict JSON overlay from the `spell_catalog` item in
-a materialized reference set. Overlay catalogs are ordered by ID, may add names
-and aliases, and may augment an existing canonical spell without replacing its
-display name. Cross-spell lookup collisions are errors. The effective view
-exposes sorted canonical names, normalized lookup, overlay identities, and a
-semantic digest; overlay content remains contextual reference material rather
-than source evidence. Its external JSON contract is defined in the
-[spell-catalog overlay contract](../integrations/dnd-spell-catalog-overlays.md).
-
-### `internal/modules/dnd/npcs/identity`, `internal/modules/dnd/npcs/registry`, and `internal/modules/dnd/codec/npcs`
-
-The NPC identity package owns Unicode comparison keys, deterministic
-`npc:sha256:` IDs, display normalization, and whole-registry collision issues.
-The registry package resolves one optional normalized artifact through the
-strict codec, validates whole-registry identity, canonicalizes its JSON, and
-provides immutable records, prompt input, semantic digest, count, and exact
-canonical-name/alias lookup. External files cross this boundary during
-preparation; generated artifacts cross it at the ordered step handoff. It owns
-the `npcs` slot and its bounded, content-safe validation failures. NPC source
-references are durable provenance and are not treated as evidence for a
-consuming pipeline. The NPC codec owns the strict durable `dnd/npc-list` JSON
-boundary and exposes candidate versus approved encode/decode operations.
-
-The `internal/modules/dnd/codec/combatturns` package owns the durable
-`dnd/combat-turn-list` schema and candidate versus approved JSON boundary. It
-is registered by the production D&D family registrar for the selectable combat
-lane.
-
-## Input Adapter
-
-### `internal/modules/seriatim/input/transcript`
-
-The adapter decodes the supported transcript JSON, selects the source identity,
-computes canonical source provenance, validates segments, and maps each segment
-into a generic source unit with a self-reference plus speaker and timestamp
-metadata. It accepts no module options. Its spec advertises the transcript
-capabilities consumed by D&D modules.
-
-Parsing is strict about required values and duplicate unit IDs but deliberately
-ignores unrelated Seriatim fields. The external format and derived-identity
-rules are defined in the
-[Seriatim contract](../integrations/seriatim.md).
-
-## Chunkers
-
-Chunkers implement `contracts.Chunker.Plan`. A plan identifies ordered source
-unit ranges and may carry optional namespaced JSON annotations; it does not
-contain materialized chunk content. The framework canonicalizes annotations,
-validates ranges against the current source, and materializes chunk IDs,
-indexes, references, content, units, and generic metadata. Materialized source
-unit metadata is independently owned. Annotation
-namespaces remain optional data: generic framework code and downstream modules
-must not require D&D scene annotations or import `dnd/scenes`.
-
-### `internal/modules/generic/chunk/units`
-
-The generic chunker validates the source document and returns ranges over units
-in configured windows. Overlap changes the next window start but never reorders
-units. Framework materialization derives the resulting chunk identity and
-generic metadata from those ranges.
-
-The accepted options and defaults are defined in
-[Configuration](../config.md#implemented-production-modules). Generic
-framework validation canonicalizes the returned unit slices before extraction.
-The chunker decodes its options during construction and retains only the typed
-window settings used by `Plan`.
-
-### `internal/modules/dnd/chunk/scenes`
-
-The scene chunker prepares a structured Scriptorium request from the full
-transcript, session, and optional D&D reference inputs. It validates the model's
-scene boundaries against source-unit IDs and converts them into deterministic
-plan ranges with optional scene annotations. Preparation injects the shared
-structured LLM client into the chunker; `Plan`
-supplies only the run-specific profile, session, source, references, and
-metadata.
-
-Scene validation requires sequential, contiguous, non-overlapping coverage from
-the first source unit through the last. Scene descriptions, boundaries,
-confidence, and participants are module-owned annotations. Boundary caveats
-become warnings. Malformed
-structured output is returned as an error; there is no fallback chunker.
-
-The package embeds its prompt and response schema and reports their non-secret
-identity and hashes through singleton module metadata. Shared D&D assets supply
-reference declarations and prompt inputs; their user-facing keys and accepted
-file types remain canonical in [Configuration](../config.md).
-
-## Extractor
-
-### `internal/modules/dnd/extract/spells`
-
-The spell extractor prepares a structured request from one chunk, the
-chunk-scoped source input, the session, and optional D&D reference inputs. It
-decodes the model response, assigns the generic source identity to every source
-reference, canonicalizes duplicate references, orders spell casts by their
-earliest cited unit, and returns `dnd.SpellList`.
-
-The extractor owns its private model-response DTO, embedded prompt, LLM response
-schema, strict option decoder, injected shared LLM client, and prompt/schema
-manifest metadata. During preparation it resolves the optional `spell_catalog`
-reference into an immutable effective catalog and adds a generated
-canonical-name-only JSON input to every structured completion request. Overlay
-failures therefore stop construction before source parsing or an LLM call;
-campaign references remain separate disambiguation inputs and never become
-source evidence.
-
-The prompt limits each cast to its declaration and immediate resolution; it
-does not follow summoned creatures, persistent effects, or other downstream
-consequences through the scene. Shared extraction-evidence and identity rules
-require transcript-supported factual claims and the most specific in-world
-caster identity, while campaign references only disambiguate source text.
-Effects describe the session as played: model rules knowledge cannot supplement
-or correct the transcript, and nonstandard adjudication is attributed to the GM
-or table rather than stated as a universal rule. Structural source validation
-remains deterministic; semantic claim completeness is enforced through
-extraction policy and evaluation.
-
-Both the extractor and deterministic catalog validator expose
-the effective base-plus-overlay semantic digest as scoped prepared-component
-checkpoint identity. Raw overlay provenance independently covers file-byte
-changes, while the semantic digest also invalidates reuse when the embedded
-catalog or catalog composition changes. The extractor additionally fingerprints
-its complete prompt assets and private response schema, so either semantic
-contract changing invalidates previously recorded extraction checkpoints. The separate
-`internal/modules/dnd/codec/spells` package
-owns the durable schema and stable JSON representation for artifact kind
-`dnd/spell-list`. The runner keeps the result typed through validators and later
-stages, using the codec only for checkpoint, debug, and output boundaries.
-Shared D&D helpers keep prompt input
-names and source-unit reference conversion consistent with the scene chunker.
-
-The extractor also declares the optional `npcs` registry slot and consumes the
-immutable registry boundary from `internal/modules/dnd/npcs/registry`. An
-external registry is prepared before execution; a generated registry is
-validated and supplied at operation time. External bindings may add only
-`npc_registry_digest` and `npc_count` to module metadata and an
-`npc_registry` checkpoint fingerprint. Generated bindings are represented by
-framework handoff provenance and dependency fingerprints. The unbound prompt
-input is exactly `{"npcs":[]}` and has no registry provenance or fingerprint.
-The shared NPC grounding fragment is placed immediately after the common
-campaign reference message and is included in the spell prompt fingerprint.
-
-The durable payload and manifest metadata shapes are defined in the
-[D&D spell artifact contract](../integrations/dnd-spell-artifacts.md).
-
-### `internal/modules/dnd/extract/npcs`
-
-The NPC extractor maps private model output to the canonical `dnd.NPCList`,
-assigns source identity and deterministic NPC IDs, and preserves source
-references for deterministic validation. It uses the shared campaign
-references only for disambiguation and does not consume the optional NPC
-registry slot. Its prompt and private response schema are package-owned. The
-prompt follows the shared D&D extraction ordering and cache policy documented
-in [LLM Runtime](llm.md#dd-extraction-prompt-ordering-and-cache-boundaries).
-
-### `internal/modules/dnd/extract/combatturns`
-
-The combat extractor prepares one structured request per supplied chunk using
-the shared extraction-evidence, identity, campaign-reference,
-immediate-resolution, NPC-grounding, and transcript prompt inputs. It
-maps the private response to `dnd.CombatTurnList`, assigns the current source
-identity, removes exact duplicate source ranges, and orders turns by valid
-source-document position while preserving malformed candidate fields for
-deterministic validators. Its package-owned private response schema enforces
-only the structural JSON envelope; semantic artifact constraints remain with
-the validator chain. Its prepared metadata and checkpoint fingerprints contain
-only prompt/schema/mapping identities plus an optional NPC registry digest.
-The prompt follows the shared D&D extraction ordering and cache policy
-documented in
-[LLM Runtime](llm.md#dd-extraction-prompt-ordering-and-cache-boundaries). The
-package exposes typed registration and is included in the production D&D
-registrar with the default combat extraction chain.
-
-The combat normalizer accepts only the optional structured NPC registry.
-Campaign references remain extractor-only LLM context and are not materialized
-for deterministic normalization.
-
-### `internal/modules/dnd/normalize/npcs`
-
-The NPC normalizer performs deterministic identity-aware consolidation in
-merged input order. It unions only canonical identity or canonical/alias
-matches, retains the first display record, unions exact relationships and
-source references, rewrites unambiguous relationship targets, and leaves
-ambiguous collisions for identity validation. It exposes the identity policy
-as its local checkpoint fingerprint and emits bounded normalization warnings.
-
-## Merger And Normalizer
-
-### `internal/modules/generic/merge/appendorder`
-
-The merger passes typed values to an injected combine function in framework
-source-chunk order. The D&D registrar specializes it with a spell-list append
-function.
-
-### `internal/modules/generic/normalize/noop`
-
-The normalizer returns the merged domain value unchanged and is reusable for
-any registered artifact type.
-
-### `internal/modules/dnd/normalize/spells`
-
-The typed spell normalizer resolves the optional `spell_catalog` reference into
-the same immutable SRD-plus-overlay effective catalog used by spell extraction
-and catalog validation. It performs no LLM calls. For each spell cast it
-canonicalizes recognized names using the catalog's case, whitespace,
-apostrophe, and alias rules; sorts source references by source identity and
-unit boundaries; removes only exact reference duplicates; and emits bounded,
-scoped warnings for each mutation or unresolved name.
-
-After those per-cast changes, it collapses only casts with the same canonical
-spell, case-folded and whitespace-normalized caster, and complete non-empty
-valid source-reference set. It retains the first occurrence and its caster,
-effect, narrative description, and stable order. Unknown names, empty or
-invalid evidence, and adjacent or overlapping but different ranges remain
-unchanged for validation.
-
-The normalizer exposes the effective catalog digest as its independently scoped
-`effective_catalog` checkpoint fingerprint and reports catalog base ID, digest,
-and overlay IDs as manifest metadata. Catalog contents, reference paths, and
-raw overlay bytes are not included in either surface. The normalize-stage
-reference is stage-local, so an overlay-capable pipeline binds the catalog
-independently for extraction and normalization.
-
-### `internal/modules/dnd/normalize/combatturns`
-
-The combat normalizer prepares an external NPC registry before execution or
-receives a generated registry at the ordered step handoff, then uses the
-immutable view during runtime. It display-normalizes combat fields,
-rewrites exact canonical-name or alias matches for actors and targets, orders
-and deduplicates source references, stable-sorts records by source-document
-position, and collapses only exact duplicate identities with fully valid
-evidence. It deep-clones output storage and emits bounded warnings scoped to
-merged input indexes. Its metadata and fingerprints identify the normalization
-and NPC identity policies. External bindings may contribute registry
-digest/count metadata; generated identity is retained in framework provenance
-and dependency fingerprints. The normalizer is included in the production D&D
-registrar with the default combat normalization chain.
-
-## Output Encoder
-
-### `internal/modules/generic/output/json`
-
-The JSON encoder sorts normalized results by lane, derives collision-checked
-safe logical names, pretty-prints JSON payloads, and assembles the logical index,
-manifest, rejected-result, warning, and lane files. Invalid JSON, unsupported
-media types, unsafe names, and sanitized-name collisions are errors.
-
-The encoder returns logical files only. The CLI places them on disk, and the
-[JSON output contract](../integrations/json-output.md) defines their external
-paths and schemas.
-
-## Generic Validators
-
-The generic validator implementations live under
-`internal/modules/generic/validate`.
-
-The unconditional accept and reject validators provide explicit chunk and
-typed-artifact variants used primarily for controlled composition and tests.
-
-The serialized JSON syntax validator uses `encoding/json` to reject malformed
-representation bytes. The serialized JSON Schema validator requires schema
-bytes, parses the instance and schema with `jsonschema`, and distinguishes
-payload rejection from schema loading or compilation errors. The framework
-serialized-validation request carries either canonical chunk bytes or artifact
-codec bytes according to its target context. Neither validator calls the LLM.
-
-## D&D Spell Validators
-
-All four validators receive `dnd.SpellList` directly. The shape validator
-rejects missing or empty spell fields and empty reference lists. The catalog
-validator defers when shape is invalid, then checks every non-empty spell name
-against the immutable effective SRD and overlay catalog. It accepts normalized
-canonical names and aliases without rewriting the artifact; unknown names
-reject the complete result with bounded, stable index/name diagnostics. The
-source-reference validator defers malformed shapes, validates every cited
-range, and reports all range defects through a bounded aggregate while
-preserving `invalid_source_refs`. The relatedness validator resolves all cited
-ranges through the shared document-order traversal, then warns when a normalized
-consecutive spell-name token sequence is absent from the cited source text.
-Invalid shape
-or cited ranges produce no relatedness warnings; the shape and source-reference
-validators own those defects.
-
-These validators are deterministic. Shape, source-reference, and relatedness
-each expose a local semantic `policy` checkpoint fingerprint. The catalog
-validator instead exposes its effective catalog digest as its semantic
-checkpoint identity and does not add a separate policy fingerprint. Their
-selectable keys and production order are defined in
-[Configuration](../config.md#implemented-production-validators); their durable
-payload rules are defined in the
-[artifact contract](../integrations/dnd-spell-artifacts.md).
-
-## D&D NPC Validators
-
-NPC shape validation checks required strings, arrays, and source-reference
-shape. The source-reference validator defers malformed shapes, checks
-current-document identity, unit existence, and range ordering, and reports all
-defects through bounded aggregates. Source relatedness uses the shared
-document-order traversal and normalized consecutive-token matching, emitting at
-most one bounded warning per record when neither the canonical name nor an
-alias occurs near its cited text. Invalid shape or cited ranges produce no
-relatedness warnings. Normalize identity validation checks deterministic IDs,
-canonical names, aliases, and cross-record ownership or canonical collisions.
-All are deterministic and expose the policy fingerprints used by the
-production chains.
-
-## D&D Combat Validators
-
-Combat shape validation owns required arrays, strings, nullable values, positive
-rounds, and supported enums. Combat source-reference validation defers invalid
-shape, checks source identity, unit existence, and range order, and reports all
-defects through bounded aggregates. Combat source-relatedness defers invalid
-shape or ranges, uses the shared traversal to combine overlapping cited units
-in document order, and emits at most one bounded advisory warning per turn for
-unrelated actors or declaration text.
-Actors use normalized consecutive-token matching; declarations retain the
-minimum four-rune token heuristic. The normalized-invariants
-validator owns display normalization, comparison-unique targets, canonical
-source-reference order, chronology, and exact duplicate identity; it defers
-shape and source-reference failures. All four validators are deterministic and
-expose local policy fingerprints. The D&D registrar orders them after generic
-JSON and response-schema validation at extraction and normalization.
-
-## Production Registration
-
-Production composition occurs through family registrars. The CLI allocates one
-complete framework registry set and one LLM asset registry. It invokes
-`internal/modules/generic/register`,
-`internal/modules/seriatim/register`, and `internal/modules/dnd/register` in
-that order, then exposes the matching catalog for resolution. The generic and
-Seriatim registrars own their production leaf registrations. The D&D registrar
-owns D&D leaf registrations, typed spell, NPC, and combat default-validator
-chains, typed append-order specializations, and D&D prompt/schema asset
-collection. Its registration helpers group module, validator, prompt-asset, and
-chain composition while retaining artifact-specific merge and clone behavior in
-the registrar.
-
-Concrete implementation packages do not import generic implementation
-packages directly. A concrete family's `register` package is its composition
-point for specializing reusable generic implementations, while the generic
-registrar composes only generic children.
-
-Core and framework production packages do not import production extensions.
-CLI production code is the sole application composition root for extensions
-and imports only exact family registrar packages. Other production packages,
-including commands and newly introduced package trees, do not import module
-packages directly. Compatibility tests in the CLI, core, and framework trees
-may import roots and implementation leaves directly. Other non-module tests do
-not receive that exemption. White-box tests within module families retain the
-production family boundaries. `internal/modules/integration` is test
-infrastructure: its black-box tests may compose multiple families, but it is
-not a production module family or production dependency target.
-
-## Adding An Extension
-
-When adding a production module or validator:
-
-1. implement the stage or validator contract and package-local key;
-2. expose and test its spec, constructor, and registration function;
-3. keep format or domain parsing inside the concrete package;
-4. add package-owned prompt/schema assets when the extension is LLM-backed;
-   new LLM-backed D&D extraction modules must follow the stable-to-variable
-   prompt ordering, shared-asset ownership, and cache-boundary policy in
-   [LLM Runtime](llm.md#dd-extraction-prompt-ordering-and-cache-boundaries), or
-   document the implemented exception and its evidence there;
-5. register it through its package-family registrar and add a default chain
-   there only when production policy requires one;
-6. add resolution and composition coverage for capabilities, options,
-   references, and validation behavior;
-7. update the selectable-key catalog in [Configuration](../config.md), the
-   relevant external contract, this inventory, and maintained examples when
-   user-visible behavior changes.
-
-Do not add the extension to `docs/development.md`; that file routes by task and
-does not inventory implementations.
-
-## Tests To Inspect
-
-- Package-local `*_test.go` files under the module or validator being changed.
-- `internal/framework/pipeline/typed_resolution_test.go`: typed registry, spec,
-  and heterogeneous artifact composition.
-- `internal/framework/pipeline/profile_test.go`: framework binding defaults and
-  profile resolution.
-- `internal/cli/production_contract_test.go`: production catalog, config
-  resolution, and composition smoke coverage.
-- `internal/cli/example_contract_test.go`: maintained example ownership.
-- `internal/framework/promptfs/*_test.go` and
-  `internal/modules/dnd/shared/*_test.go`: shared prompt and reference assembly.
-- `internal/modules/integration/*_test.go`: black-box composition across
-  production extension domains.
+# Module Internals
+
+This guide owns the mechanics for implementing and registering production
+modules. [Configuration](../config.md) owns selectable keys, binding syntax,
+reference configuration, and default validator chains. Durable input and output
+shapes belong in [integration contracts](../integrations/).
+
+The D&D family has additional shared conventions and domain-specific
+exceptions. See [D&D Module Internals](dnd.md) rather than adding them here.
+
+## Module Boundary
+
+A module is a typed implementation registered for one pipeline stage. Its
+`ModuleSpec` is the public-to-the-framework declaration of its stable key,
+stage, execution class, required and provided capabilities, artifact kind, and
+accepted reference slots. The execution class states whether a module is
+`deterministic` or `llm_backed`; registries retain it for catalog inspection and
+resolved-pipeline debug data without constructing the module. The framework
+uses the declaration to resolve a configured binding before it builds the
+implementation. After selection, the resolver applies profile inheritance only
+to bindings whose declared execution class is `llm_backed` and rejects a
+binding-specific profile on a deterministic module. The user-facing precedence
+contract belongs in [Configuration](../config.md#pipelines).
+
+Implementations that accept options must provide both an option validator and
+a builder. The validator is used while resolving configuration; the builder
+decodes the same options and constructs the implementation from the prepared
+`BuildRequest`. Reject unknown options in both paths. A builder receives only
+the dependencies and materialized references that the framework prepared for
+that operation, so it must not re-read configuration or files.
+
+Registry helpers register the typed builder for a stage-specific registry.
+They are preferable to hand-written untyped registration because they retain
+the artifact type at the framework boundary. Registrars validate the registries
+they need, register each leaf implementation, and add any family-owned assets
+or default validator chains. They return contextual errors so production
+composition fails at startup rather than at the first run.
+
+An artifact family can register an optional typed evidence projector alongside
+its codec. The projector returns defensive copies of the artifact's direct
+generic source references and must use the codec's exact Go type. It does not
+interpret surrounding context or publish files; the pipeline validates the
+capability during preparation and the output boundary owns publication. See
+the [Published Evidence Context contract](../integrations/evidence-context.md)
+for the durable result.
+
+## Production Composition
+
+Production composition is intentionally split by family:
+
+- The generic registrar provides the unit chunker, generic JSON validators,
+  and JSON output encoder.
+- The Seriatim registrar provides the transcript input adapter. Its external
+  input behavior is defined by the [Seriatim contract](../integrations/seriatim.md).
+- The D&D registrar provides its codecs, extractors, mergers, normalizers,
+  validators, prompt assets, fallback profile asset, and default chains. Its behavioral conventions
+  are documented in [D&D Module Internals](dnd.md).
+
+The CLI owns the composition that invokes these registrars. A module package
+may register its own family but must not assemble the CLI or make framework
+packages depend on production extensions.
+
+## Adding Or Changing A Module
+
+1. Choose the pipeline stage and the typed artifact boundary. Put external
+   input or durable artifact formats in the relevant integration contract,
+   not in this guide or in a private LLM response type.
+2. Define a stable `ModuleSpec` with an explicit execution class, the exact
+   capabilities, and reference slots needed for the operation. Model a
+   producer/consumer handoff as an artifact-compatible slot; configuration
+   then chooses an external file or a generated binding.
+3. Implement strict option decoding, construction, and the typed stage
+   interface. Preserve caller ownership: do not retain mutable request data
+   and return defensive copies where an implementation exposes stored data.
+4. Register the module through its typed registry helper and add it to the
+   owning family registrar. Add a default validator chain only when that
+   family owns the behavior; otherwise require an explicit compatible chain.
+5. Update the selectable-key and chain reference in
+   [Configuration](../config.md#production-module-keys), the applicable
+   integration contract, and focused tests. Keep the configuration document
+   as the sole list of production keys and validator order.
+
+## Validation And References
+
+Validators operate on the value produced at their configured stage. A default
+chain is ordered behavior, not a set: JSON parsing, structural checks,
+domain-specific checks, durable-schema checks, and advisory checks may have
+different responsibilities and failure handling. The active default chains and
+override rules are maintained in
+[Configuration](../config.md#production-validator-keys-and-default-chains).
+
+Reference slots are part of the module specification. They describe the
+accepted artifact kind, media type, size, and whether a binding is required;
+the framework validates those constraints before construction. An external
+reference is materialized during preparation. A generated reference is a
+compatible normalized artifact handed from an earlier pipeline step at
+operation time. The configuration reference rules, including precedence and
+ordered-handoff requirements, are maintained in
+[Configuration](../config.md#references-and-ordered-handoffs).
+
+## Focused Verification
+
+Exercise the leaf implementation and its registration path when changing a
+module. Registry and registrar tests cover duplicate keys, required registries,
+and typed construction; pipeline resolution tests cover capabilities, options,
+and reference compatibility. Domain packages should additionally test their
+codecs, validators, normalizers, and any integration handoffs they own.
+
+Run the affected package tests while iterating. The complete module suite is:
+
+~~~sh
+go test ./internal/modules/...

 # Internal Overview
 
-This document inventories the implemented Notarius components. Normative
+This document is the implemented component map for Notarius. Normative
 boundaries and dependency direction belong in
-[Architecture](../policy/architecture.md); external behavior belongs in the
-[CLI](../cli.md), [Configuration](../config.md),
+[Architecture](../policy/architecture.md). User and operator contracts belong
+in the [CLI](../cli.md), [Configuration](../config.md),
 [Operations](../operations.md), and [integration contracts](../integrations/).
 
 ## Execution Path
 
-`cmd/notarius` delegates to `internal/cli`, the production composition root.
-The CLI loads configuration, builds the production catalogs and runtime
-collaborators, invokes `internal/framework/pipeline`, and places the logical
-output files returned by the runner. Cache and debug collaborators are supplied
-at this boundary.
+~~~
+cmd/notarius -> internal/cli -> configuration and production composition
+             -> internal/framework/pipeline -> logical output files
+             -> internal/cli -> durable output and optional state/debug data
+~~~
 
-Resolution produces a fixed ordered workflow of steps and globally unique,
-sorted artifact lanes. Preparation constructs the complete module and validator
-set before the runner receives source bytes. Source parsing and chunking are
-serial. Each step then uses a bounded run-wide extraction pool followed by
-serial per-lane merge and normalize continuations. A step barrier prevents
-later consumers from starting until all earlier lanes are terminal and their
-required normalized artifacts have crossed the typed handoff.
+The CLI is the application boundary: it discovers configuration, composes
+production registries and runtime collaborators, invokes the framework, and
+places returned files. The framework resolves and prepares a fixed extraction
+pipeline, then returns logical results without owning process behavior or
+physical state roots.
 
-## Application Boundary
+## Components
 
-| Package | Implemented responsibility |
-| --- | --- |
-| `cmd/notarius` | Executable entry point and process exit delegation. |
-| `internal/cli` | Command parsing, config discovery, package-family registrar invocation, LLM client construction, reference materialization, state collaborator setup, durable writes, and user-facing results. |
-
-## Core Packages
-
-| Package | Implemented responsibility |
-| --- | --- |
-| `internal/core/artifacts` | Run-manifest and provenance models. |
-| `internal/core/config` | Defaults, YAML parsing, environment overrides, validation, redaction, and effective pipeline resolution. |
-| `internal/core/debugbundle` | Explicit per-run debug-bundle allocation and redacted summary writing. |
-| `internal/core/fileio` | Generic confined atomic file and JSON writes with caller-selected permissions. |
-| `internal/core/source` | Generic source documents, units, chunks, canonical references, validation, deterministic source digests, and independent metadata materialization. |
-
-## Framework Packages
-
-| Package | Implemented responsibility |
-| --- | --- |
-| `internal/framework/contracts` | Source-stage contracts plus artifact identity, schema, serialized representation, codec, validator, reference, output, and structured-completion interfaces and data types. |
-| `internal/framework/pipeline` | Module and artifact-codec registries, ordered-step and generated-reference resolution, option validation, profile resolution, capability checks, external reference materialization, complete pipeline preparation, typed handoff, retries, orchestration, warnings, checkpoint decisions, and manifest population. |
-| `internal/framework/validate` | Shared validator decision and cardinality helpers. |
-| `internal/framework/llm` | Scriptorium-backed structured completions, prompt/schema registration, scheduling, profile recording, and secret redaction. |
-| `internal/framework/promptfs` | Builds module prompt filesystems from module-owned and caller-provided shared prompt assets. |
-| `internal/framework/checkpoint` | Root-based checkpoint loading, recording, identity, and payload serialization. |
-| `internal/framework/chunkplan` | Source-addressed chunk-plan filesystem storage, envelope validation, and atomic publication. |
-| `internal/framework/debug` | Root-based framework and LLM debug recording. |
-
-Framework contracts provide typed artifact, provenance-wrapper, chunk-validator,
-serialized-validator, and
-typed-validator interfaces. The runner owns handoff provenance, validation
-sequencing, rejection handling, checkpoint and debug boundaries, and final
-manifest assembly.
-
-Artifact registries support heterogeneous typed extraction entries and
-kind-specific merger, normalizer, and validator variants. Resolution derives a
-lane's kind from its extractor, requires the matching codec, verifies exact Go
-type equality across the lane, and records schema identity in the resolved lane
-and pipeline digest. Registry entries carry separate option-validation and
-run-local construction closures. Preparation injects shared dependencies and
-constructs input, chunk, validators, ordered lanes, and output before source
-parsing. Production modules use strict construction-time option decoding, and
-LLM-backed modules retain the injected shared client. The D&D family registers
-the canonical `dnd/spell-list`, `dnd/npc-list`, and `dnd/combat-turn-list`
-codecs, typed spell, NPC, and combat extractors and normalizers, validators,
-plus kind-specific generic merge strategies; generic JSON validators use the
-serialized-validation contract. The runner executes lanes through
-private exact-type-checked closures, coordinates extract results independently
-of completion timing, and serializes artifacts only through their codec at
-checkpoint, debug, and output boundaries.
-
-## Production Extensions

-| `internal/modules/generic/normalize/noop` | Preserves accepted merged output. |
-| `internal/modules/dnd/normalize/spells` | Canonicalizes catalog-backed spell names and exact source references, conservatively collapses duplicate casts, and reports deterministic warnings and independently scoped catalog checkpoint identity. |
-| `internal/modules/dnd/normalize/npcs` | Consolidates NPC records deterministically by identity and aliases, rewrites unambiguous relationship targets, and reports bounded warnings. |
-| `internal/modules/generic/output/json` | Encodes manifests, lane payloads, warnings, and rejections as logical JSON files. |
-
-`internal/modules/dnd/shared` owns reusable D&D prompt fragments,

-and bounded diagnostics under `internal/modules/dnd/shared/diagnostics`.
-The shared NPC grounding fragment is mounted for D&D prompts and is owned by
-this package. Domain-neutral prompt filesystem composition lives in
-`internal/framework/promptfs`.
-
-The `dnd/npcs/registry` package owns the optional `npcs` registry boundary.
-External references are strictly decoded and identity-validated during
-preparation; generated references are decoded and identity-validated at the
-ordered step handoff. Both paths emit canonical registry JSON to operation-time
-spell and combat prompt or normalization requests. The framework records
-generated identity and bounded producer provenance, while the raw external
-reference remains independently tracked by pipeline provenance. An absent
-registry is represented only by the empty prompt value `{"npcs":[]}`. Spell
-and combat consumers use this shared boundary without changing their public
-module contracts.
-
-Generic validators under `internal/modules/generic/validate` provide
-unconditional test decisions, JSON syntax validation, and JSON Schema
-validation. D&D spell validators under `internal/modules/dnd/validate/spells`
-consume the canonical spell-list type directly to provide shape,
-effective-catalog, source-reference, and source-relatedness decisions.
-
-Production composition is grouped behind package-family registrars, and every
-implemented production extension uses its domain-first tree:
-
-| Package | Implemented responsibility |
-| --- | --- |
-| `internal/modules/generic/register` | Registers domain-neutral chunk, merge, normalize, output, and validator implementations. |
-| `internal/modules/seriatim/register` | Registers the Seriatim input adapter. |
-| `internal/modules/dnd/register` | Registers D&D modules, validators, default validator policy, and prompt/schema assets. |
-
-The CLI allocates the framework registries and asset registry, then invokes
-these registrars in generic, Seriatim, and D&D order.
-
-Implementation details for all production extensions are in
-[Module Internals](modules.md).

 # Pipeline Internals
 
-The implemented resolver and runner live in `internal/framework/pipeline`.
-Their fixed workflow and ownership boundaries are defined by
-[Architecture](../policy/architecture.md#system-shape). Configuration fields,
-defaults, and selectable keys are defined in
-[Configuration](../config.md#pipelines).
+This document describes the framework-owned pipeline mechanics in
+**internal/framework/pipeline**. [Configuration](../config.md) owns selectable
+profiles, bindings, and retry settings; [Operations](../operations.md) owns
+state lifecycle and recovery; and the [integration contracts](../integrations/)
+own durable output shapes. Concrete production extensions are covered by
+[Module Internals](modules.md).
 
-Resolution fixes the ordered steps, selected lanes, and all stage bindings;
-preparation constructs every selected implementation before the runner begins
-source work. After serial input parsing and plan selection or generation, the
-runner materializes chunks and executes one step at a time. Within a step,
-extract work uses one bounded run-wide worker pool in chunk-first, lane-second
-order. Each lane's merge and normalize operations remain serial, and lanes in
-the same step may overlap once their extracts are terminal. A later step cannot
-start across its barrier until every earlier lane is terminal and each required
-generated artifact has been accepted and handed off.
+## Boundary
 
-## Resolution
+The pipeline framework accepts a resolved composition, registries, shared
+dependencies, input bytes, and state/debug collaborators. It returns logical
+output files, normalized artifacts, recorded rejections and warnings, manifest
+provenance, and checkpoint decisions. The CLI owns process arguments,
+configuration discovery, physical roots, and placement of returned output
+files.
 
-`internal/core/config.Config.Resolve` validates the loaded configuration,
-selects the named profile, applies the runtime inputs supplied by the CLI, and
-calls `pipeline.ResolvePipeline`.
+The framework has one fixed shape:
 
-`ResolvePipeline`:
+~~~
+input -> chunk -> extract -> merge -> normalize -> output
+~~~
 
-1. selects the explicit ordered steps, or creates the implicit `default` step
-   from the legacy top-level `artifacts` map;
-2. selects and sorts artifact lanes within each step while enforcing global lane
-   identity;
-3. completes omitted bindings using the documented configuration defaults;
-4. looks up each module and validator spec without constructing it;
-5. for a typed extractor, derives its artifact kind, requires the codec, and
-   selects exact-type merger, normalizer, and validator variants;
-6. checks required and provided capabilities in workflow order;
-7. resolves external and generated target-aware reference bindings and
-   validates producer order, consumer slot declarations, and artifact-kind
-   compatibility;
-8. validates each selected module and validator option set through its registry
-   entry; and
-9. calculates a digest over the resolved structure, including step order, step
-   IDs, lane membership, generated topology, producer and consumer identities,
-   typed artifact kind and schema identity, and the effective validator policy
-   in its resolved execution order.
+Input and chunking are pipeline-wide. A selected artifact lane owns extract,
+merge, and normalize; output aggregates the terminal lane outcomes. A pipeline
+is an ordered list of steps, not an arbitrary workflow graph.
 
-Resolution returns a `ResolvedPipeline` containing ordered steps, lanes,
-concrete bindings, validator chains, reference targets, and the digest. It does
-not read external reference bytes or construct runtime modules. CLI lane and
-reference selector syntax is defined in the [CLI reference](../cli.md#run).
+## Resolve, Materialize, Prepare
 
-The digest includes each resolved step's ID and lane membership, generated
-producer/consumer topology, and each validator chain's stage, lane, owning
-module, ordered validator bindings, execution classes, targets, and artifact
-kinds. Changing step order, a dependency, a default chain, or an explicit
-override therefore changes pipeline identity whenever it changes effective
-execution policy.
+Resolution turns a configured pipeline profile into a **ResolvedPipeline**.
+It normalizes the pipeline and lane identities, applies stage defaults, selects
+requested lanes where that is supported, resolves validator chains, checks
+module capabilities and typed artifact compatibility, validates options, and
+assigns a deterministic resolved-composition digest. The resolved pipeline
+contains bindings and declared reference targets, not external reference bytes.
+After selection, the resolver applies command, binding, and pipeline profile
+precedence to LLM-backed bindings and validators only; prompt defaults remain
+an empty resolved binding profile. Deterministic bindings remain profile-free.
+These effective values are part of the digest, so execution and checkpoint
+consumers do not repeat profile inheritance.
+Configuration resolution supplies the selected profile and catalog; see
+[Configuration Internals](configuration.md).
 
-## Reference Materialization
+External reference materialization happens before preparation. The materializer
+checks that each slot is declared by the selected module, resolves a file path
+relative to the correct configuration or working-directory origin, reads
+UTF-8 text, verifies media type and size limits, and retains bounded
+provenance. A generated-artifact selector remains declared but has no bytes
+until its producing step completes.
 
-The CLI calls `MaterializeReferences` after resolution and before constructing
-the LLM client or running the pipeline. For external bindings, the materializer
-checks each binding against its resolved target declaration, reads and validates
-the file, and builds both a `contracts.ReferenceSet` and provenance-only
-metadata on the corresponding `ResolvedReferenceTarget`. A structured
-generated binding is declaration-only at this point: its producer bytes do not
-exist until the producer lane reaches an accepted normalized result.
+Preparation is the construction boundary. It validates the resolved shape and
+registry set, clones the resolved data, then constructs the input adapter,
+chunker, stage-local validators, every typed lane, and output encoder with
+cloned options, references, and shared dependencies. It also collects stable
+checkpoint fingerprints. Missing registrations, incompatible typed entries,
+nil implementations, and constructor failures are reported before source
+parsing or any stage operation begins.
 
-Preparation delivers the materialized external set for each target through
-`pipeline.BuildRequest`: chunkers and chunk validators receive the chunk target;
-extractors and extract validators receive the lane extract target; mergers and
-merge validators receive the lane merge target; and normalizers and normalize
-validators receive the lane normalize target. Input and output builders receive
-an empty set because those stages cannot declare references. Every builder gets
-an isolated deep clone of its target set, so construction-time mutation cannot
-change another builder, the resolved pipeline, or later runtime requests.
+An output encoder can opt into source-evidence publication through its output
+policy. Preparation keeps the configured lane allowlist and active lanes
+separate, then verifies an exact typed evidence projector and registered codec
+for each active lane. The resulting private plan is immutable; lanes excluded
+by invocation filtering remain configured but do not acquire a projector for
+that run.
 
-Prepared consumers do not need to be reconstructed when generated content is
-available. At the step boundary, the runner encodes the accepted producer value
-through its registered canonical codec, validates the generated bytes against
-each target slot's kind, schema, media type, and size, and clones one immutable
-reference item into the operation request. The item includes canonical digest,
-size, and bounded producer provenance but no filesystem URI. A handoff failure
-is a framework dependency error and prevents every consumer in that step from
-starting.
+## Typed Lanes And References
 
-The runner continues to clone the resulting set into the chunk, extract, merge,
-or normalize request that owns the target. LLM-backed extensions may convert
-those items into named prompt inputs. Reference content remains separate from
-source evidence and source digests, whether the item came from a file or a
-generated handoff.
+Each resolved lane has one artifact kind, codec, and exact Go type. The
+framework uses private type erasure only around those typed operations; every
+handoff checks exact type and codec identity and reports incompatibility as an
+error rather than panicking. Encoding through the registered codec is the
+boundary for output, checkpoints, debug records, and generated references.
 
-Binding precedence, path resolution, accepted content, and media-type behavior
-are configuration contracts; see [Configuration](../config.md#pipelines).
-Durable provenance is defined in the
-[JSON output contract](../integrations/json-output.md#manifestjson), while
-runtime sensitive-data handling belongs in [Operations](../operations.md).
+Reference targets are stage- and lane-specific. External reference bytes are
+cloned into the operation request. Generated references are built at the next
+step boundary from exactly one accepted normalized producer output. The
+framework decodes and re-encodes that output with the registered producer
+codec, checks its complete schema and media identity, and records a content
+digest plus bounded producer provenance. A missing, ambiguous, invalid, or
+incompatible producer prevents the consumer step from starting.
 
-## Registries And Specs
+## Execution And Ordering
 
-`pipeline.Registries` holds option validators and run-local builders used during
-resolution and preparation.
-`pipeline.ModuleCatalog` exposes their specs during configuration validation and
-resolution. Separate registries exist for every stage and for validators;
-`ValidatorChainRegistry` stores production default-chain mappings. Both
-containers also carry an `ArtifactCodecRegistry`. Generic registration records
-one codec per stable artifact kind, validates its schema metadata and JSON
-Schema, retains the exact schema digest and Go type, and safely encodes or
-decodes framework-erased values with typed errors on incompatibility.
+The runner validates its input, installs no-op state collaborators when none
+were supplied, and serially performs source parsing and chunk-plan selection.
+An accepted plan is materialized into source-addressed chunks and passes the
+configured chunk validators before any lane runs. A chunk rejection is a
+recorded pipeline outcome: lanes do not start, but the output stage can encode
+the terminal result.
 
-Typed extractor entries are keyed by module key and declare one artifact kind.
-Merger, normalizer, and typed-validator variants are keyed by module or
-validator key plus artifact kind. Chunk and serialized validators occupy
-separate target namespaces; serialized registrations declare whether they
-support chunks, artifacts, or both. Duplicate variants and exact Go-type
-mismatches are rejected deterministically.
+For each ordered step, the runner first builds generated reference sets from
+the accepted normalized outputs of earlier steps. It then executes the step's
+lanes. Later steps do not begin until the current step is terminal and its
+generated handoffs have succeeded.
 
-Lane-sensitive merger and normalizer spec discovery always supplies the
-extractor's artifact kind, so variants under one reusable key may declare
-different capabilities and reference slots. Kind-neutral registry inspection
-selects the first registered artifact kind in sorted order.
+Within a step, the lane engine dispatches extraction jobs in deterministic
+chunk-first, lane-second order to a bounded worker group. When all extraction
+jobs for one lane are terminal, a bounded continuation group can run that
+lane's merge and normalize work while extraction for other lanes continues.
+The framework does not create an unbounded goroutine per chunk or lane.
 
-Production composition registers the D&D spell-list codec and typed extractor,
-matching typed merge, normalize, and semantic-validator variants, and
-serialized JSON validators. Every artifact lane resolves through the typed
-registries and a matching codec.
+Completion timing does not determine public results. The coordinator restores
+lane and chunk order before merging results, and selects a framework error by
+stable stage, lane, and chunk position. A validator rejection records a lane
+outcome without cancelling unrelated work. A framework error or parent
+cancellation cancels derived work, prevents queued work from starting, waits
+for started workers, and prevents output encoding.
 
-A `ModuleSpec` declares its stage plus required and provided capabilities.
-Chunk, extract, merge, and normalize specs may also declare reference slots.
-Registry implementations defensively copy spec metadata, reject duplicate keys,
-and verify that a constructed implementation reports the registered key.
-Builder registrations accept `ModuleDependencies` and cloned configuration
-options through one `BuildRequest`. Builders decode those options and retain
-typed values or injected dependencies in the constructed implementation.
-Extractors declare their artifact kind, and merger, normalizer, and validator
-resolution selects the matching typed variant.
+## Validation, Retries, And Output
 
-A `ValidatorSpec` declares a validator key and execution class. Resolution uses
-the execution class to reject incompatible profile bindings before execution.
-The current production catalog and default chain are listed only in
-[Configuration](../config.md#implemented-production-validators).
+Every chunk, extract, merge, and normalize candidate passes its resolved
+validator chain. Validators receive immutable canonical input appropriate to
+their target: chunks, typed values, or serialized codec bytes. They may
+approve, approve with warnings, reject, or fail. A rejection is an ordinary
+pipeline result; a validator error is a framework error.
 
-## Preparation And Runner Boundary
+The runner applies the binding's retry policy around a stage operation and its
+complete validation chain. It preserves warnings only from the final accepted
+or rejected attempt. Cancellation stops retries. Normalizer-specific retry
+directives consume this same budget and validate any final safe fallback through
+the normalizer chain.
 
-`pipeline.Prepare` receives a resolved pipeline, the registries, and shared
-module dependencies. It constructs input; chunk and its validators; every
-step's lane extract, merge, and normalize modules and validator chains in
-resolved order; then output. It stops at the first error with pipeline, step,
-stage, lane, module, and validator context as applicable. It never invokes an
-operation method. Generated references are not available during preparation;
-the operation request is the handoff boundary.
-
-`PreparedPipeline` keeps private constructed executors and exposes cloned
-resolved input, chunk, lane, and output identities. Prepared components may
-implement `pipeline.CheckpointFingerprintProvider` to contribute explicit
-semantic identities to checkpoint reuse. Preparation trims and validates each
-non-secret name and value, prefixes it with the component's stage, lane,
-module, and validator scope, rejects duplicates, and retains the resulting
-sorted collection behind a defensive-copy accessor. Fingerprints must be
-stable and must not contain source content, credentials, local paths,
-timestamps, or other invocation-specific values.
-
-`pipeline.RunInput` carries that prepared pipeline, raw source input, run identity and timing, optional
-session and profile metadata, a chunk-plan store and mode, a checkpoint
-execution policy, and checkpoint/debug collaborators. The runner
-parses source bytes through the already constructed input adapter. Later stage
-requests receive the generic source model; extract requests receive
-chunk-scoped input material, while chunk, merge, and normalize requests retain
-access to the original source material. Input, chunk, and output operation
-requests do not carry raw module options. The chunk request also does not carry
-an LLM client; an LLM-backed chunker receives the shared client during
-preparation. Their operation requests retain run-specific source, reference,
-profile, session, metadata, and step-handoff context as applicable. A generated
-reference is cloned into each compatible consumer request and is never exposed
-as a path.
-
-Prepared lanes retain exact-type-checked erased operation closures. The runner
-uses those closures to keep each value typed through extraction, validation,
-merge, and normalization.
-
-Source validation requires every unit to carry a canonical self-reference to
-its containing document and its own unit ID. Explicit clone, checkpoint, and
-debug boundaries retain that reference, and the canonical source digest covers
-it deterministically. Chunks use the same source model and carry one canonical
-reference spanning the first selected unit through the last.
-
-`pipeline.RunOutput` carries the run manifest, accepted normalized serialized
-artifacts with lane and normalizer provenance,
-rejected results, warnings, checkpoint events, and logical files returned by the
-output encoder. The CLI owns debug-summary and durable filesystem writes after
-the runner returns.
-
-## Execution Flow
-
-The pipeline-wide coordinator owns the ordered step loop, generated-reference
-sets at each barrier, and deterministic merging of step outcomes. For one step,
-the lane engine initializes checkpoint state in lane order, dispatches bounded
-extract work, advances terminal lanes through serial merge and normalize work,
-selects failures by stable pipeline scope, and merges lane-local outcomes back
-in resolved order. Completion timing never becomes public ordering.
-
-The runner:
-
-1. validates its prepared input;
-2. parses the raw input with the prepared adapter and validates the generic
-   source document;
-3. selects a stored plan or executes the configured chunker's `Plan` operation;
-4. canonicalizes and materializes the plan, then validates the resulting
-   chunks;
-5. executes each resolved step in configuration order. For one step, it
-   dispatches extract jobs in source-chunk then resolved-lane order, starts a
-   bounded lane continuation when all extracts for that lane are terminal, and
-   waits for every lane to become terminal;
-6. encodes and validates each accepted normalized producer artifact, then
-   builds the immutable generated reference sets for the next step;
-7. invokes the prepared output encoder only after every step succeeds and
-   validates its logical file results;
-8. returns the assembled manifest, outcomes, warnings, and files.
-
-Within each artifact lane, it reuses the prepared extractor, merger, normalizer,
-and validators while performing these transitions:
-
-1. extract once per accepted chunk and add runner-owned lane, source, and chunk
-   provenance;
-2. validate each extract result and omit rejected results from merge input;
-3. skip the rest of the lane when no extract result is accepted;
-4. merge accepted extract results in their existing order;
-5. validate the merge result and skip normalization on rejection;
-6. normalize the accepted merge result;
-7. validate and append the accepted normalized result.
-
-At a step barrier, a lane with no accepted normalized output is still a regular
-rejection unless a later generated binding names that lane as a required
-producer. In that case the runner raises a deterministic dependency error and
-does not start the consumer step. One accepted typed artifact may fan out to
-multiple compatible target slots. Consumers in the same step may run
-concurrently after the handoff; no work crosses the barrier early.
-
-Module-provided warnings and payload warnings are promoted only from attempts
-whose results are accepted and used.
-
-## Chunk Plans And Reuse
-
-`Chunker.Plan` returns a `source.ChunkPlan`: the canonical source digest,
-ordered unit-ID ranges, and optional plan or range annotations. The framework
-owns plan canonicalization and materialization. It creates the generic chunks
-and therefore owns their IDs, indexes, source references, JSON content, units,
-media type, and generic metadata. Plan and range annotations are independently
-owned raw JSON and become `Chunk.PlanAnnotations` and `Chunk.Annotations`.
-
-In `auto`, the runner looks up the source digest before invoking the chunker. A
-valid hit is materialized and sent through the current run's configured chunk
-validators; it does not invoke the chunk module, consume its retry budget, or
-make a chunk-stage LLM call. A missing, invalid, or unmaterializable record
-generates a candidate. `refresh` generates without lookup; `bypass` generates
-without cache access. Generated plans are published only after the full chunk
-validator chain approves them. A validator rejection is a regular rejected
-pipeline outcome and never replaces a cached plan.
-
-The store is source-addressed, not pipeline-addressed. Changes to pipeline
-configuration, requested chunker, options, references, lanes, validators, or
-LLM profile do not prevent a source-digest hit. The manifest records both the
-currently requested chunker and the effective plan producer. Cache state and
-paths are configured and operated outside the runner; see
-[Configuration](../config.md#state-surfaces) and [Operations](../operations.md).
-
-The extract job channel has the same capacity as the effective extract worker
-count, so dispatch applies backpressure. A fixed continuation executor prevents
-ready or checkpoint-reused lanes from creating one goroutine each. Workers and
-continuations publish lane-local results; the coordinator is the only writer of
-aggregate output and merges those results in resolved lane and source-chunk
-order.
-
-## Plan Canonicalization And Chunk Materialization
-
-Plan canonicalization requires canonical JSON annotations, a matching source
-digest, at least one range, existing ordered boundaries, and increasing range
-starts. Ranges may overlap or leave gaps; a chunker may impose stricter policy.
-Materialization deterministically reconstructs each range from the current
-source document, deep-clones JSON-shaped source-unit metadata, and copies
-annotations without interpreting their namespaces. Materialized chunks and
-separate materializations do not share mutable unit metadata; unsupported or
-cyclic metadata fails materialization with context.
-
-Before lane execution, generic chunk validation checks the materialized chunks'
-identities, order, source references, content, media type, units, and metadata.
-No chunk checkpoint participates in plan selection: plan storage is the only
-chunk-reuse mechanism. Extract, merge, and normalize checkpoints continue to
-use materialized chunk digests as their dependencies.
-
-## Validation And Retries
-
-Chunk, extract, merge, and normalize results pass through the resolved validator
-chain for their stage and module. Chunk validators receive canonical chunks;
-typed validators receive the domain value; and serialized validators receive
-canonical chunk JSON or artifact codec bytes. Validators execute in resolved
-order and stop at the first error or rejection. An empty chain approves the
-result.
-
-`runWithRetry` applies the effective retry policy around module execution and
-its complete validation chain. A module or validator error becomes a framework
-error when attempts are exhausted. A rejection becomes a recorded
-`RejectedOutput` when attempts are exhausted. Cancellation stops retry
-processing immediately.
-
-Rejected output is a non-fatal pipeline outcome and does not advance. Warnings
-from discarded attempts are not promoted. Configuration owns retry counts and
-validator overrides; see [Module Bindings](../config.md#module-bindings).
+After terminal lane work, the runner assembles manifest provenance, normalized
+artifacts, rejections, warnings, and an optional accepted chunk map. When an
+output policy selected evidence lanes, it decodes accepted serialized normalize
+outputs through their registered codecs and invokes the prepared typed
+projectors. Rejected or absent lanes contribute nothing. This reconstruction is
+also used after normalized-checkpoint reuse, so no second typed output channel
+is retained. The runner passes the resulting owned artifact to the output
+encoder, which returns logical files and does not choose a physical directory.
+The CLI publishes those files only after the runner returns without a framework
+error. Logical file names and schemas are defined by the [output integration
+contracts](../integrations/).
 
 ## Checkpoint And Debug Hooks
 
-The runner depends on recorder and loader interfaces, using no-op
-implementations when collaborators are absent. Each checkpointed workflow
-boundary records a running, succeeded, or failed transition. Reuse decisions
-are consulted in workflow order and accepted payloads are cloned before
-entering the normal handoff path. Typed extract, merge, and normalize
-checkpoints store codec bytes with artifact kind, schema ID, name, version and
-exact digest, and media type. Reuse compares that identity with the prepared
-codec and decodes through the codec; missing identity, mismatches, corrupt
-bytes, and decode failures become explicit reuse misses and execute the lane
-normally. Dependency fingerprints and debug content digests use the same stable
-codec bytes that cross those boundaries.
+The runner receives checkpoint and debug interfaces rather than roots. It
+records workflow transitions and reuse decisions through the supplied
+collaborators, and clones reusable artifacts before they re-enter normal typed
+handoff. Generated-reference dependencies participate in checkpoint decisions.
+Selective recomputation can require a canonical accepted normalized predecessor
+before a dependent lane starts.
 
-That progressive extract, merge, and normalize reuse is the ordinary resume
-path. A lane marked as a required predecessor for selective recomputation takes
-a separate accepted-output path before extract scheduling. The loader reads the
-existing successful normalize manifest and payload by step, lane, and
-normalizer, without consulting extract or merge dependencies. It requires the
-current non-empty checkpoint identity to match, so the invocation identity
-still binds the input, resolved topology and configuration, references, runtime
-overrides, profiles, and component fingerprints.
+Debug recording is attempt-scoped and application-owned. A failure to persist
+required debug data is a framework error. State roots, persistence, reason-code
+meanings, resume, and cleanup are intentionally owned by
+[Run State Internals](state.md) and [Operations](../operations.md).
 
-The runner decodes that accepted normalized artifact with the prepared codec,
-re-encodes it, and requires exact kind, schema identity and digest, media type,
-canonical bytes, content digest, and producer provenance. A valid result becomes
-a runner-owned cloned normalized output, restores only normalize-checkpoint
-warnings, and records one `accepted_artifact_reused` normalize decision. It does
-not invoke or record extract, merge, normalize, or their validators. Invalid or
-unavailable accepted state records its decision and fails the producer step;
-the dependent step never starts and the producer is not implicitly rerun.
+## Invariants To Preserve
 
-Generated references add downstream dependencies containing the producer's
-artifact kind, complete schema identity, media type, canonical content digest,
-and size. Compatible accepted producer outputs may therefore feed a later step

+- The six fixed stages remain explicit; a pipeline is not a general DAG.

+- Generated references come only from one earlier accepted normalized producer
+  and carry canonical identity rather than an unverified value.
+- Rejections are recorded outcomes; framework errors cancel derived work and
+  prevent output encoding.
+- Public ordering and selected errors are independent of goroutine completion

-Debug instrumentation wraps run, stage, attempt, validator, and structured LLM

-one terminal envelope for acceptance, validator rejection, module or validator
-error, or applicable candidate or final serialization error. The envelope
-contains its attempt-local warnings, any available candidate and rejection,
-and terminal error text; failures before a candidate exists omit that payload.
-Only LLM calls made by the module operation belong to the module attempt.
-Validator calls retain independent scopes under `validate/` and are not
-duplicated into the module envelope. A failed terminal-envelope write is a
-non-retryable framework error and is joined with any primary attempt error.
-Debug data is never used as a checkpoint source. Typed artifact debug envelopes
-are domain-neutral, redact sensitive metadata and bytes through the common
-debug policy, and record codec identity plus schema and content digests.
-
-Merge and normalize attempts serialize their in-memory candidate with the
-codec's required candidate encoder before typed validation. Serialized
-validators and attempt debug use that candidate representation, which carries
-the codec media type and schema identity but is never checkpointed or passed
-downstream. Only a validator-approved value is encoded through the strict final
-codec and made eligible for a checkpoint or stage output.
-
-Checkpoint identity, physical layout, reuse behavior, and debug artifact

-and recorder implementation are inventoried in

-## Results And Failures
-
-The runner owns manifest assembly and handoff summaries but not the durable JSON
-schema. It records resolved module and lane provenance, validator chains,
-source/reference identities, selected LLM profiles, normalized and rejected
-summaries, status, and timing. Serialized artifact content remains outside the manifest.
-Module metadata providers may add non-secret singleton or lane-scoped metadata.
-
-Execution errors include stage, module, lane, or validator context. Once a
-manifest exists, a failing run returns it with failed status and completion
-time. Successful status reflects whether any result was rejected. The
-durable manifest and logical file schemas are defined in the
-[JSON output contract](../integrations/json-output.md).
-
-On a framework failure, the runner cancels its derived context, stops submitting
-new extract work, drains started tasks, and skips the output encoder. Parent
-cancellation takes precedence. Otherwise context-cancellation fallout is
-discarded when a substantive error exists, and the primary error is selected by
-stage, resolved lane, and source chunk rather than completion time.

 # Operations
 
-This is the canonical guide to operating Notarius filesystem state. Command
-syntax is in the [CLI reference](cli.md); field definitions and precedence are
-in [Configuration](config.md).
+This is the canonical guide for operating Notarius runtime state. The
+[CLI reference](cli.md) owns command syntax and exit statuses, while
+[Configuration](config.md) owns fields, defaults, and precedence. Maintainers
+who need implementation mechanics should read [Run State Internals](internal/state.md).
 
-## State Model
+## State Surfaces
 
-Notarius uses three independent filesystem surfaces:
+Each run can use independent roots with different retention and access-control
+needs.
 
-- output is durable user data;
-- cache is reconstructible chunk-plan and checkpoint state; and
-- debug is explicitly requested inspection data.
+| Surface | Purpose | Created when | Retention |
+| --- | --- | --- | --- |
+| Output | Durable user-facing result bundle | A pipeline completes and returns logical output files | Keep until consumers no longer need it. |
+| Chunk-plan cache | Reconstructible source-addressed plan | The configured cache mode permits cache I/O | Keep while reuse is useful. |
+| Checkpoint cache | Reconstructible execution and recovery state | Checkpoint recording is enabled | Keep only while recovery or reuse is useful. |
+| Debug bundle | Explicit diagnostic record | A run requests debug collection | Keep only under an intentional sensitive-data retention policy. |
 
-Choose separate roots and access controls for each surface. A normal run writes
-durable output, may use the chunk-plan cache, and records checkpoints when
-`cache.checkpoints.enabled` is true. It does not create debug state unless its
-invocation includes `--debug`.
+Output, cache, and debug roots are never merged or cleaned automatically. Use
+separate locations and permissions for operators or services that must not
+share application data.
 
-## Output
+## Roots And Permissions
 
-Durable logical files are written under:
+The configured output and debug directories are exact roots. An empty cache
+directory selects a per-user root:
 
-```text
+~~~
+<os.UserCacheDir>/notarius/chunk-plans
+<os.UserCacheDir>/notarius/checkpoints
+~~~
+
+The field definitions and configuration examples are in [Configuration](config.md).
+On supported Unix systems, output directories and files are created with
+requested modes **0755** and **0644**. Chunk-plan, checkpoint, and debug
+directories and files use **0700** and **0600**. The operating system's umask
+may impose stricter output modes. Cache and debug roots may contain sensitive
+source-derived data, so provision them for one trusted account or service. An
+output bundle can also contain source content when its JSON output enables
+evidence publication. Apply an appropriate umask and output-root access policy
+before enabling that option; the requested output modes alone may not be
+suitable for transcript-bearing bundles.
+
+## PromptKit Profile Deployment
+
+Profile deployment has four distinct layers:
+
+| Layer | Owner | Operational role |
+| --- | --- | --- |
+| Prompts and schemas | Notarius module families | Embedded request and structured-output definitions. They are not deployment profile files. |
+| Fallback profiles | Notarius module families | Embedded application defaults, including D&D's `dnd-extraction` profile. |
+| Built-in profiles | PromptKit | Upstream catalog entries available when no higher-precedence source defines an ID. |
+| Operator profiles | Deployment filesystem | Complete environment-specific definitions selected by `promptkit.profile_file` or `promptkit.profile_dir`. |
+
+The maintained D&D pipeline uses the workload ID `dnd-extraction`. The
+embedded fallback makes that ID usable without an operator file. Production,
+development, and local deployments can each install a different complete
+definition for the same ID, retaining the pipeline while choosing their own
+model, backend, timeout, or reasoning policy. An operator definition wins over
+the fallback; it is not merged with it. The configuration field and full
+precedence rules are owned by [Configuration](config.md#promptkit-profiles).
+
+Use a profile source owned by the service account, keep it readable only by
+the intended operator, and supply provider credentials through the service
+environment—not in the Notarius configuration or profile YAML. The maintained
+[operator profile](../examples/profiles/dnd-extraction.yml) is secret-free and
+can be copied as a format starting point. Validate a deployment without a
+provider call or credentials:
+
+~~~sh
+notarius config validate --config /etc/notarius/config.yml --pipeline dnd-session
+~~~
+
+Profile paths are currently resolved from the process working directory, not
+from the configuration file. The complete example's
+`./examples/profiles/dnd-extraction.yml` path is valid for a repository-root
+invocation only. Use absolute paths such as
+`/etc/notarius/profiles/dnd-extraction.yml` for services and containers.
+
+## Run Lifecycle
+
+Use the [run command](cli.md#run) to start a pipeline. A valid invocation loads
+and resolves configuration before module preparation and source parsing. It
+then performs any permitted cache lookup, executes the pipeline, and publishes
+logical output files only after a successful runner result.
+
+On success, the command reports the output bundle path. A warning-bearing run
+still succeeds and reports its warning count on standard error. Errors and
+their exit classes are defined in the [CLI reference](cli.md#output-streams-and-exit-statuses).
+
+## Output Bundles
+
+Each successful run receives a generated safe run identifier and writes beneath:
+
+~~~
 <output-root>/<run-id>/
-```
+~~~
 
-The CLI generates one run ID in the form
-`run-<started-at-unix-nanoseconds>-<32-lowercase-hex-characters>` and uses it
-for output, manifests, and any requested debug bundle. It validates every
-logical output name before exclusively creating the run directory. If that
-directory already exists, the invocation fails without changing it.
+The [JSON output contract](integrations/json-output.md) owns the logical files
+and their schemas. Before creating the run directory, Notarius validates every
+logical output path. It refuses an existing run directory without changing it.
+Files are written atomically; if a later write fails, the newly created partial
+run directory remains for inspection and is never removed automatically.
 
-Each output file is written atomically. A later file-write failure leaves the
-newly allocated partial run directory in place for inspection; Notarius never
-automatically removes output. The
-[JSON output contract](integrations/json-output.md) owns the logical file
-names, schemas, and media types inside a run directory.
-
-Remove an output run directory only after its consumer data is no longer
-needed. This is data deletion, not cache cleanup.
-
-## Ordered D&D Workflow
-
-The maintained [NPC-grounded configuration](../examples/dnd-npc-grounded.config.yml)
-contains one pipeline with two ordered steps. The first step extracts and
-normalizes NPCs. Only after that lane reaches an accepted terminal result does
-the second step begin; its generated NPC reference is supplied in memory to
-spell extraction, combat extraction, and combat normalization.
-
-```sh
-go run ./cmd/notarius run dnd-npc-grounded \
-  --config examples/dnd-npc-grounded.config.yml \
-  --input examples/seriatim-minimal-transcript.json \
-  --output-dir ./npc-grounded-output
-```
-
-The NPC artifact grounds canonical names and aliases, not spell or combat
-evidence. Current-transcript source ranges remain the only event evidence. The
-manifest records generated-reference identity and bounded producer provenance;
-it does not record generated payload content, and no generated content is
-exposed through a filesystem path. The same producer artifact may fan out to
-compatible consumers, while a missing or rejected producer prevents the later
-step from starting.
-
-Standalone module configurations continue to support external NPC files when a
-workflow intentionally crosses a process or session boundary. Those files are
-validated against the consumer slot and must be protected as sensitive
-campaign data. They are not part of the maintained ordered handoff workflow.
+Treat an output bundle as durable user data. Do not use cache-cleanup policy to
+remove it. An optional accepted chunk map is also durable output and can carry
+source- or model-derived annotations; its content and compatibility contract
+are defined in [Accepted Chunk Map](integrations/chunk-map.md). An optional
+[evidence context](integrations/evidence-context.md) contains source-unit text
+and metadata. It is not a cache or debug artifact: retain it with the output
+bundle only for as long as consumers need it, and apply source-content access
+controls to the entire bundle. Selected lanes may collectively cite most of a
+transcript, so a broad allowlist can make the evidence artifact nearly as
+sensitive and large as the source itself.
 
 ## Chunk-Plan Cache
 
-Chunk plans are stored at:
+Chunk plans live beneath the selected chunk-plan root:
 
-```text
+~~~
 <chunk-plan-root>/<source-sha256-hex>/plan.json
-```
+~~~
 
-`auto` reuses a complete valid plan or regenerates missing or invalid state.
-`refresh` regenerates and atomically replaces a plan after chunk validation.
-`bypass` performs no plan-cache I/O and does not resolve or create the root.
-Plan selection is source-addressed and independent of checkpoint and debug
-roots.
+One validated canonical plan is active for each source digest. The plan stores
+boundaries and provenance, not a second copy of the entire source. This
+source-addressed policy is recorded in [ADR-0005](adr/0005-cache-canonical-chunk-plans-by-source.md).
 
-When its directory is empty in configuration, the root is
-`<os.UserCacheDir>/notarius/chunk-plans`. A configured directory is the exact
-root; no suffix is appended. Directories and files created by the store use
-`0700` and `0600` permissions on supported Unix systems. The configured root
-is a trust boundary: do not share it among mutually untrusted users.
+The configured cache mode controls one invocation:
 
-Remove an exact digest directory or the configured root only when accepting the
-cost of recomputing plans and any chunk-stage work. Cache publication is atomic;
-there is no history, locking, garbage collection, or rollback facility.
+- **auto** looks for a valid active plan. Missing or invalid state causes a new
+  plan to be generated; an accepted new plan is atomically published.
+- **refresh** skips lookup, generates a plan with the configured chunker, and
+  atomically replaces the active plan after it is accepted.
+- **bypass** performs no chunk-plan cache I/O. It does not resolve or create a
+  chunk-plan root.
 
-For a Linux service account, provision a dedicated restrictive root such as:
+A reused plan is still materialized and validated against the current source.
+If a prior plan no longer gives acceptable results, use a refresh run rather
+than editing cache files. Deleting a plan is recoverable but can repeat costly
+chunking work.
 
-```yaml
-cache:
-  chunk_plans:
-    directory: /var/cache/notarius/chunk-plans
-```
+## Checkpoint Recording, Resume, And Recompute
 
-## Checkpoint Cache
+Checkpoint recording is an explicit configuration choice and is disabled by
+default. When enabled, each run records stage transitions and the state needed
+for compatible recovery. A run records checkpoints even when it does not ask
+to reuse them. Checkpoint payloads can contain source-derived and intermediate
+application data, so treat the entire root as sensitive.
 
-Checkpoint recording is controlled by `cache.checkpoints.enabled`, which
-defaults to `false`. When enabled, every run records running, succeeded, and
-failed transitions and reusable validator-approved results. Successful,
-rejected, and failed runs may therefore all leave checkpoint state. The
-`--resume` flag additionally loads compatible completed work before executing
-missing or incompatible stages. Without `--resume`, a recording-enabled run
-never loads checkpoints. Using `--resume` while recording is disabled is an
-error.
+Checkpoint loading is separate: [**--resume**](cli.md#run) asks a run to reuse
+compatible recorded work. A resume request fails when checkpoint recording is
+disabled. Without **--resume**, a recording-enabled run executes normally and
+does not load checkpoint state. Compatibility includes the resolved pipeline,
+input, selected lanes, runtime overrides, reference provenance, LLM-profile
+provenance, the effective PromptKit profile-source fingerprint, and
+prepared-component fingerprints. When a local PromptKit backend is configured,
+compatibility also includes a non-secret fingerprint of its endpoint. Changing
+profile content or the local endpoint causes a cold miss; changing only the
+local concurrency limit does not. A changed identity produces a cold miss;
+Notarius does not migrate, rewrite, or delete older checkpoint directories.
+Reasoning-effort inheritance, replacement, and explicit clearing are distinct
+runtime identities, so checkpoints created under one state are not reused by
+either of the others.
 
-Checkpoints use the selected root and the existing identity hierarchy:
+Checkpoint state is confined below an identity-specific path:
 
-```text
-<checkpoint-root>/<pipeline-id>/<input-key>-<source-or-input-digest>/<pipeline-digest>/<identity-digest>/...
-```
+~~~
+<checkpoint-root>/<pipeline-id>/<input-key>-<source-or-input-digest-prefix>/<pipeline-digest-prefix>/<identity-digest-prefix>/
+~~~
 
-The final identity digest includes stable semantic fingerprints explicitly
-contributed by prepared modules and validators. Adding or changing one of
-these fingerprints intentionally causes a cold cache miss; old checkpoint
-directories are left in place and are never migrated or deleted automatically.
+### Selective Recompute
 
-An empty configured directory selects
-`<os.UserCacheDir>/notarius/checkpoints`. The root is exact when configured.
-Created directories and files use `0700` and `0600` permissions on supported
-Unix systems.
+[**--recompute-step**](cli.md#run) requires both **--resume** and enabled
+checkpoint recording. It forces the selected ordered step and every lane that
+depends on it through generated artifact references. Unrelated lanes remain
+eligible for reuse.
 
-Checkpoint payloads can contain source text, intermediate artifacts, metadata,
-warnings, and content digests. Treat them as sensitive derived application
-data. Compatible files from a former checkpoint root remain reusable when
-`cache.checkpoints.directory` names that exact existing root. They are not
-moved, migrated, or deleted automatically. The frozen serialized identifier
-`workspace_schema_version` remains part of checkpoint compatibility; it is not
-a configuration setting.
+For an earlier producer required by a forced consumer, Notarius requires a
+compatible accepted normalized artifact. It validates that artifact before
+hydrating it and does not silently rerun the producer. If that state is
+missing, rejected, corrupt, non-canonical, or incompatible, the run stops
+before its dependent starts. Rerun the required producer deliberately instead
+of copying or editing checkpoint files.
 
-For a Linux service account, independently provision:
+## Checkpoint Decisions And Recovery
 
-```yaml
-cache:
-  checkpoints:
-    enabled: true
-    directory: /var/cache/notarius/checkpoints
-```
+Checkpoint events classify work as **executed**, **reused**,
+**forced_recompute**, or **dependency_invalidated**. Their stable reason codes
+are written to run diagnostics and provenance. Use the code, not a copied
+error message, to decide what to repair.
 
-Remove an exact checkpoint identity directory or the configured root only when
-recomputation is acceptable.
-
-### Resume And Selective Recompute
-
-`--resume` loads compatible accepted work only when checkpoint recording is
-enabled. A normal resumed run may reuse source, extract, merge, and normalize
-checkpoints independently and may recompute a stage after a cache miss.
-Generated references add a dependency fingerprint
-for the producer's artifact kind, schema identity, media type, canonical
-content digest, and size. If that fingerprint changes or the producer is
-missing, dependent checkpoints are invalidated; unrelated work remains eligible
-for reuse.
-
-`--recompute-step <step-id>` requires both `--resume` and
-`cache.checkpoints.enabled: true`. It forces the named step and all transitive
-dependents to execute, while compatible predecessors and unrelated lanes remain
-reusable. The ID may be an explicit configured step or `default` for an
-implicit single-step pipeline. It cannot be combined with `--only`, and it does
-not change the persistent identity of otherwise identical checkpoints.
-Decisions are bounded and categorized as `reused`, `executed`,
-`forced_recompute`, or `dependency_invalidated`.
-
-For an unselected producer required by a recomputed step, Notarius loads the
-accepted normalized artifact directly. Valid normalize state is sufficient even
-when that producer's extract or merge checkpoint is missing or corrupt. The
-normalize manifest must be successful and match workspace schema v3, the exact
-current invocation identity, step, lane, and normalizer; its payload digest and
-canonical codec representation must also validate. A forced producer bypasses
-this lookup and executes.
-
-If a required predecessor's accepted normalized artifact is missing, rejected,
-corrupt, non-canonical, or incompatible, the run fails before the dependent
-step starts. It does not fall back to rerunning that predecessor. The failure
-manifest retains completed upstream outcomes and dependency context but not
-generated reference content. For diagnosis, first check the producer step and
-lane in the manifest, then inspect checkpoint decision categories and reason
-codes. Rerun the producer explicitly rather than copying an artifact into the
-checkpoint root.
-
-The decision that caused a required-predecessor failure is retained before the
-run returns, and the CLI error identifies its step, lane, and reason code.
-
-Checkpoint reason codes are stable diagnostic identifiers:
-
-| Reason code | Operator meaning |
+| Reason code | Recovery meaning |
 | --- | --- |
-| `loading_disabled` | This invocation did not enable checkpoint loading. |
-| `checkpoint_missing` | The requested checkpoint file does not exist. |
-| `checkpoint_path_invalid` | The requested checkpoint location failed confinement validation. |
-| `checkpoint_read_failed` | An existing checkpoint could not be read. |
-| `checkpoint_decode_failed` | Checkpoint JSON could not be decoded. |

-credentials, or environment values.
+Reason detail is bounded code-owned text. It is diagnostic information, not a
+path-discovery or data-recovery mechanism, and does not contain checkpoint,
+source, reference, credential, or environment content.
 
 ## Debug Bundles
 
-Only `notarius run --debug` enables debug collection. The selected root contains
-one retained bundle per invocation:
+Only a [debug-enabled run](cli.md#run) creates a bundle:
 
-```text
+~~~
 <debug-root>/<run-id>/
   summary/
   trace/
-```
+~~~
 
-`summary/` contains redacted invocation, effective-configuration, resolved
-pipeline and reference provenance, checkpoint and chunk-plan decisions, run
-manifest, warnings, report, and any available error text. It excludes raw
-source, references, annotations, prompts, model responses, credentials, and
-malformed cache bytes.
+The summary contains redacted invocation and resolution information plus run,
+warning, checkpoint, chunk-plan, and terminal reporting artifacts. The trace
+contains allowlisted application diagnostic records and can include source or
+derived application data. Neither surface is a cache input. Do not treat a
+debug bundle as safe to share merely because its configuration summary is
+redacted. Invocation metadata omits reasoning effort when it is inherited,
+records the replacement value when one is supplied, and records an empty value
+when inherited reasoning was explicitly cleared.
 
-`trace/` contains application-owned execution detail, including source and
-stage material, plans, chunks, validator attempts, prompts, model responses,
-timing, and serialized artifacts. It may retain application data omitted from
-output. Credentials, credential-shaped values, sensitive metadata, unrelated
-environment values, and unrelated filesystem content are not captured.
-
-Bundles inherit the sensitivity of the application data they capture. Their
-additional risk comes from copying and aggregating that data, so restrict
-access, avoid shared roots between untrusted users, and define retention outside
-Notarius. Created bundle directories use `0700` and files use `0600` on
-supported Unix systems.
-
-Notarius never automatically deletes a requested bundle. If allocation
-succeeds, its path is reported on success and failure. A requested summary or
-trace write failure makes the command fail, preserving whatever bundle data was
-already written for inspection. Every allocated bundle makes one best-effort
-attempt to record a terminal `run-report.json`.
-
-## Failures And Warnings
-
-Failures before debug allocation are reported on stderr without a bundle.
-Failures after allocation report the bundle path on stderr and make independent
-attempts to write a failure `run-report.json` and `error.log`. The report retains
-the paths and pipeline outcome fields known at the failure point. If either
-terminal write fails, the original command error remains first on stderr,
-followed by the persistence error and bundle path. An output-write failure
-leaves the allocated bundle in place. A successful run with warnings exits `0`,
-reports a warning count on stderr, and records warnings in durable output and
-any requested debug summary.
+Notarius never creates debug state without an explicit request and never
+automatically deletes a requested bundle. If allocation succeeds, the command
+reports its path on both success and later failure. A summary, trace, or
+terminal-report persistence failure fails the command while preserving any
+already-written diagnostic data for inspection.
 
 ## Cleanup
 
-Use exact paths for manual cleanup. Examples:
+Cleanup is manual and destructive. First inspect the exact leaf directory,
+then remove only that leaf; do not use a glob or a parent root as the target.

-Avoid broad recursive cleanup against a parent root unless it is an explicit
-operator policy. Output deletion is permanent user-data loss. Cache deletion is
-recoverable but can repeat expensive work. Debug deletion removes troubleshooting
-evidence and any retained application-data copy.
+Deleting output permanently removes user data. Deleting chunk plans or
+checkpoints is recoverable but may repeat expensive provider or pipeline work.
+Deleting a debug bundle removes troubleshooting evidence and a retained copy of

+or automatic cleanup command.
 
 ## Operational Limits
 
-Provider retries and timeouts are handled by Scriptorium according to the
-selected execution profile. Pipeline module retry settings are defined in
-[Configuration](config.md#module-bindings). Extract worker concurrency and
-actual provider-call concurrency are separate limits; their fields and
-validation are defined in [Configuration](config.md#concurrency). Notarius
-writes local files only; remote storage and archive management are outside the
-implemented CLI.
+Provider execution settings and the generation timeout come from the selected
+PromptKit profile. The invocation-only **--reasoning-effort** and
+**--clear-reasoning-effort** controls may replace or clear that profile setting
+for all LLM-backed calls in one run without changing the profile. PromptKit
+v0.5.0 does not add a provider retry loop. Notarius binding retries rerun the
+complete module operation and validation chain as defined by
+[module bindings](config.md#module-bindings-and-validators).
+
+Timeouts are layered. Caller cancellation is the outer authority. A positive
+effective generation timeout adds an inner request deadline, while zero
+disables only that generation deadline. The HTTP client timeout remains a
+transport-wide cap. Notarius does not add another timeout around PromptKit.
+The pinned upstream boundary and profile-format links are in
+[PromptKit Integration](integrations/pkg-promptkit.md).
+
+Concurrency has two independent layers. Notarius **total_llm** is the
+application-wide provider-call limit shared by all backends, modules, retries,
+and validators. PromptKit may impose a narrower admission limit for the
+selected backend. The effective active-generation bound is the intersection of
+both limits and can therefore be lower than **total_llm**. Built-in OpenRouter
+profiles use PromptKit's upstream backend limit; endpoint-only profiles have no
+PromptKit backend limit and remain bounded by Notarius. For the configured
+local backend, a zero **concurrency_limit** leaves only the Notarius scheduler
+as a call limit. A positive value makes the effective active local-generation
+bound the smaller of **total_llm** and that local limit.
+
+For a positive local limit, PromptKit owns its default waiting capacity and
+admission behavior. When a PromptKit backend has admitted all active and queued
+work, a new call fails as capacity exhaustion before generation. The adapter
+maps that failure to Notarius's existing provider-neutral capacity error and
+does not retry it. The calling stage's configured retry policy applies
+normally, and the run fails if those attempts are exhausted. Caller
+cancellation remains authoritative. Configuration contracts are documented
+under [PromptKit profiles](config.md#promptkit-profiles) and
+[concurrency](config.md#concurrency-output-cache-and-debug). Extract-worker
+limits and actual provider-call limits are independent. Notarius writes local
+filesystem state only; remote storage, archival, and retention automation are
+outside the implemented CLI.

+

+
+- Replace the source-document-ID default for prompt sessions with one

+- Preserve an explicit non-empty `--session-id` as the highest-precedence
+  override. Otherwise, derive the default only from the effective input module
+  identity and the exact raw input bytes.
+- Use a versioned, bounded representation such as
+  `notarius:v1:<sha256(input-module + NUL + raw-input)>`. The exact encoding
+  must fit PromptKit's session length contract and must not embed source
+  content.
+- Keep the derived session stable across runs, pipelines, selected lanes,
+  ordered steps, retries, resume, recomputation, LLM profiles, reasoning
+  overrides, and output, debug, or cache settings.
+- Do not include file-backed references, generated references, reference
+  contents, or the composition of a reference bundle in session derivation.
+  References may change between prompt calls within one pipeline without
+  changing routing affinity.
+- Resolve the authoritative session before checkpoint construction and use the
+  same value for checkpoint runtime identity, every prompt-facing module,
+  PromptKit's direct session field, the compatibility `session_id` prompt
+  variable, run-manifest metadata, and debug metadata.
+- Keep routing identity separate from cache and checkpoint content identity.
+  Exact prompt prefixes, reference contents, model settings, and other
+  generation-affecting inputs must continue to participate in their existing
+  hashes and checkpoint fingerprints even though they do not change the
+  session.
+- Treat the generated value as a provider-visible, stable pseudonymous
+  correlation identifier. Do not introduce an installation-specific HMAC or
+  secret unless a concrete multi-tenant or privacy requirement justifies
+  sacrificing deterministic identity across installations.
+
+### Raise The Default Application-Wide LLM Limit
+
+- Raise the default `concurrency.total_llm` value from 1 to 16 so ordinary
+  single-backend runs can use PromptKit's expected OpenRouter capacity and
+  lower-capacity local backends without an unnecessarily narrower Notarius
+  limit.
+- Keep the Notarius application-wide scheduler mandatory and require
+  `total_llm` to remain a positive integer. Do not make the default unlimited:
+  endpoint-only profiles, an unrestricted local backend, injected clients, and
+  aggregate work across several backends may have no narrower PromptKit limit.
+- Continue defaulting `concurrency.stage_workers.extract` to the effective
+  `total_llm`, making its default 16 as part of the same change. Preserve an
+  explicit lower extract-worker setting when an operator wants less queued or
+  concurrent extraction work.
+- Define effective provider concurrency as the intersection of the Notarius
+  application-wide limit, the selected PromptKit backend limit when present,
+  and the work made available by stage execution. A Notarius limit of 16 does
+  not narrow a backend already limited to 16, while a local backend limited to
+  4 remains bounded at 4.
+- Treat the default as an application-wide safety ceiling across profiles,
+  backends, modules, retries, and validators. A run that intentionally needs
+  the combined capacity of several backends may configure a higher
+  `total_llm` and an appropriate extract-worker count explicitly.
+- Retain the existing configuration and environment override surfaces. Update
+  canonical configuration, operations, and internal documentation together
+  when the default changes.
+- Reconsider decoupling the extract-worker default from `total_llm` only after
+  mixed-backend workloads demonstrate a need for a high global emergency
+  ceiling with a lower default work-production rate.

-# Implementation Plan: Ordered Pipeline Follow-Up
+# PromptKit v0.5 Implementation Plan
 
-## Status
+## Objective
 
-Completed on 2026-07-22. This document retains the implementation sequence for
-historical context; current contracts are maintained in the canonical CLI,
-configuration, operations, integration, and internal documentation linked from
-the [development guide](../development.md).
+Implement the target state in
+[PromptKit v0.5 Integration And LLM Profile Policy](promptkit.md). Each numbered
+stage is intended to be one implementation prompt for a GPT-5.6-Terra coding
+agent. Complete stages in order and leave the repository buildable, tested, and
+internally coherent after every stage.
 
-## Purpose
+Follow [Architecture](../policy/architecture.md),
+[Testing Policy](../policy/testing.md), and
+[Documentation Policy](../policy/documentation.md) throughout. Preserve
+unrelated user changes. Use `apply_patch` for source and documentation edits,
+run `gofmt` on changed Go files, and add only tests that protect the behaviors
+and risks assigned to that stage.
 
-Record the work that closed the correctness, observability, test, and
-maintainability gaps in the implemented
-[Ordered Pipeline Steps](ordered-pipeline-steps.md) feature. That feature
-roadmap remains the authority for product intent, policy choices, acceptance
-criteria, and exclusions. This document preserves the ordered,
-decision-complete implementation sequence for the follow-up work.
+Do not implement the separate deterministic session-ID or default-concurrency
+roadmap items as part of this plan. Do not perform paid or credentialed LLM
+calls.
 
-## Background
+## Background Summary
 
-The original implementation is complete in broad architecture. Pipelines now
-resolve and prepare one canonical ordered-step model, execute hard barriers
-between steps, hand accepted normalized artifacts to later operations as
-canonical generated references, include generated identity in checkpoint and
-output provenance, support `--recompute-step`, and use generated NPC output at
-operation time in the D&D spell and combat consumers. Current documentation and
-maintained examples describe that model.
+Notarius currently pins PromptKit v0.3.0, calls `Prepare` and then `Run` for one
+completion, validates profiles through a synthetic prompt, has no application
+fallback profile source, and accepts LLM profiles only at individual bindings
+or through the run-wide CLI override. PromptKit v0.5.0 is source-compatible
+with the current tree; a temporary v0.5.0 module override has already passed
+`go test ./...`.
 
-The completed follow-up addressed these narrower gaps:
+The implementation must nevertheless treat the upstream optional-parameter
+change as intentional: unset `temperature`, `max_tokens`, and `top_p` remain
+unset and are omitted from compatible provider requests. Do not restore the old
+implicit `top_p: 1` default.
 
-- selective recomputation now hydrates an unselected predecessor from its
-  accepted normalized artifact without requiring its extract and merge state;
-- the failed checkpoint decision is recorded before a required-predecessor
-  error returns;
-- checkpoint reason codes are assigned explicitly rather than inferred from
-  human-readable prose;
-- runner lane and checkpoint orchestration has explicit responsibility seams;
-  and
-- CLI and resumed-producer acceptance coverage exercises the complete recovery
-  contract.
+## Stage 1: Upgrade The PromptKit Dependency
 
-No new product feature is introduced by this plan. Preserve configuration file
-version 3 and checkpoint workspace schema `notarius.workspace.v3`; the fixes do
-not require a new persistent format.
+### Goal
 
-## Instructions For Every Stage
+Establish a clean PromptKit v0.5.0 baseline before adopting its new APIs.
 
-Before changing code, read `docs/development.md`, all documents under
-`docs/policy/`, and the task-specific internal documents named there. Use the
-repository's code knowledge graph for code discovery before falling back to
-text search.
+### Work
 
-Implement the stages in order. Each stage must leave the repository formatted,
-building, and passing its focused tests. Preserve these invariants throughout:
+- Update `go.mod` and `go.sum` from PromptKit v0.3.0 to v0.5.0 and run
+  `go mod tidy`.
+- Change the PromptKit built-in profile-catalog marker in
+  `internal/framework/llm/promptkit_profile_fingerprint.go` to identify
+  v0.5.0. This deliberately invalidates LLM checkpoints tied to the prior
+  catalog identity.
+- Review PromptKit-facing compile errors or test failures against the v0.4.0
+  and v0.5.0 release guides. Do not adopt prepared execution, inspection, or
+  fallback profiles in this stage.
+- Replace the existing test assertion for one exact built-in fingerprint hash
+  with durable assertions that the fingerprint is deterministic, non-empty,
+  non-secret, and changes when a semantic profile source changes. Do not add a
+  new version-constant or exact-hash change detector.
+- Update `docs/integrations/pkg-promptkit.md` to pin and link v0.5.0 and state
+  the implemented dependency-level behavior: unset optional sampling controls
+  are provider defaults. Do not document later stages as implemented.
+- Update any other canonical text that explicitly claims the dependency is
+  v0.3.0, but defer descriptions of unimplemented v0.5 APIs.
 
-- The pipeline retains one input, chunk plan, output encoder, run identity,
-  checkpoint identity, failure boundary, worker budget, and provider scheduler.
-- Every selected module and validator is constructed before source parsing.
-- Steps schedule fixed extract, merge, and normalize lanes; this work must not
-  introduce module-to-module calls or a general DAG scheduler.
-- Generated artifacts remain cloned operation-time context, never source
-  evidence. Never emit their content, source material, credentials, or local
-  paths in decisions, manifests, logs, or summaries.
-- Public ordering remains step order, lane ID, and source/chunk order as
-  applicable. Refactoring must not expose completion order.
-- Tests must follow `docs/policy/testing.md`: protect observable recovery,
-  orchestration, and CLI contracts without asserting private helper calls,
-  exact prose, goroutine choreography, or full-document snapshots.
-- Update current-behavior documentation in the same stage that changes the
-  corresponding behavior. Keep detailed implementation sequencing only here.

-- A **stage checkpoint** is internal resumable state for extract, merge, or

-  `(step ID, lane ID, normalizer module)` under the current checkpoint identity.
-  It is the dependency exposed to a later step.
-- An unselected required predecessor satisfies selective recomputation when its
-  accepted lane artifact can be validated and hydrated. Its extract and merge
-  stage checkpoints are not prerequisites for that handoff.
-- A selected lane and its transitive dependents execute. They must never use
-  accepted-artifact hydration to bypass forced execution.
-- If a required predecessor's accepted lane artifact is missing, rejected,
-  corrupt, non-canonical, or incompatible, fail the run before any dependent
-  lane starts. Do not implicitly rerun that predecessor.
-- Ordinary resume without `--recompute-step` keeps its existing progressive
-  stage-reuse and cold-miss behavior.
+- The repository directly pins v0.5.0 and all default offline checks pass.
+- The profile-source fingerprint identifies the new upstream catalog without a
+  brittle literal-hash test.
+- Current documentation no longer identifies v0.3.0 as the supported version.
 
-## Stage 1: Decompose Runner And Checkpoint Orchestration
+## Stage 2: Execute One Frozen Prepared Snapshot
 
-### Objective
+### Goal
 
-Create explicit, testable ownership seams for ordered-step coordination,
-per-lane execution, and per-stage checkpoint handling without changing
-observable behavior.
+Make Notarius debug details and generation use one exact PromptKit preparation.
 
-### Changes
+### Work
 
-1. Keep `Runner.Run` as the pipeline-wide coordinator. Extract a small
-   step-coordination helper responsible only for iterating prepared steps,
-   building generated reference sets at each barrier, invoking the lane engine,
-   and merging deterministic outcomes.
-2. Split `runLanes` in `internal/framework/pipeline/runner_concurrent.go` into
-   helpers with these responsibilities:
-   - initialize lane state and resolve extract checkpoint state in lane order;
-   - run the bounded extract worker/continuation engine;
-   - collect terminal lane results and choose failures deterministically; and
-   - merge lane-local output into step output.
-   Preserve the existing bounded channels, cancellation, drain behavior,
-   chunk-first dispatch, lane ordering, and step barrier.
-3. Split `continueTypedLane` in
-   `internal/framework/pipeline/runner_typed.go` into stage-specific merge and
-   normalize helpers. Each helper should own dependency construction, checkpoint
-   loading and canonical validation, execution/retry/validation when needed,
-   checkpoint recording, debug envelopes, and its typed result. Use small
-   result structs rather than long parallel return lists.
-4. Centralize repeated checkpoint-decision flow in one pipeline helper that can
-   apply forced-execution policy, validate canonical stored artifacts, record
-   the final observable decision, and return a contextual error. Do not yet
-   change categories, reason codes, or required-predecessor semantics; Stages 2
-   and 3 will change those deliberately.
-5. Keep stage-specific code where the data shapes genuinely differ. Do not
-   introduce reflection, a generic stage state machine, or callbacks that hide
-   the fixed extract/merge/normalize lifecycle.
+- Refactor `PromptKitClient.CompleteStructured` to call
+  `PrepareExecution`, immediately defer `Discard`, obtain a caller-owned
+  `Details` value, and execute with `RunPrepared`.
+- Preserve the existing Notarius request mapping, cancellation precedence,
+  validation classification, raw structured bytes, response decoding,
+  profile recording, usage reporting, and credential redaction.
+- Ensure every preparation, execution, validation, empty-result, and decode
+  error retains useful Notarius prompt context without exposing prepared handle
+  state or secrets.
+- Use `errors.As` to obtain `*promptkit.CapacityError` on admission rejection.
+  Preserve `contracts.ErrLLMCapacityExceeded` as the stable classification and
+  add a nonblank backend ID only to safe application-owned diagnostic context.
+  Do not expose `promptkit.CapacityError` outside the LLM adapter.
+- Update `docs/internal/llm.md` and the implemented-mechanics portion of
+  `docs/integrations/pkg-promptkit.md` to describe the single frozen execution
+  snapshot and structured capacity adaptation.
 
-### Tests
+### Tests And Validation
 
-- Existing runner, checkpoint, barrier, ordering, cancellation, retry, debug,
-  and D&D integration tests must pass without expectation changes except moves
-  required by renamed private test fixtures.
-- Add no tests for helper boundaries or collaborator call counts. Add a narrow
-  regression assertion only if the refactor exposes an observable behavior not
-  already protected.
+- Adapt existing PromptKit client tests to the prepared-execution path.
+- Retain or add one behavioral test proving that the debug prompt details match
+  the request actually passed to generation when a backing prompt source could
+  otherwise change between independent preparations. Test the resulting
+  snapshot consistency, not a private helper call count.
+- Retain capacity tests proving `errors.Is` reaches
+  `contracts.ErrLLMCapacityExceeded`, the selected backend can appear in safe
+  diagnostic context, and provider calls are not made after rejected
+  admission.
+- Run `go test ./internal/framework/llm` and
+  `go test -race ./internal/framework/llm`.
+- Run `go test ./...` and `git diff --check`.

-## Stage 2: Make Checkpoint Decisions Typed And Observable
+## Stage 3: Replace Synthetic Profile Validation With Inspection
 
-### Objective
+### Goal
 
-Assign stable decision categories and reason codes explicitly, and retain the
-decision that causes a required-dependency failure.
+Validate profiles through PromptKit's exact profile-inspection boundary and
+centralize engine profile-source construction.
 
-### Changes
+### Work
 
-1. In `internal/framework/pipeline/checkpoint.go`, introduce string-backed
-   internal types and constants for checkpoint decision categories and reason
-   codes. Keep the current JSON strings and public artifact fields compatible.
-   Categories remain exactly `executed`, `reused`, `forced_recompute`, and
-   `dependency_invalidated`.
-2. Replace prose inspection in `internal/framework/checkpoint/loader.go` with an
-   explicit decision constructor accepting category, reason code, and optional
-   detail. Remove every `strings.Contains` classification branch. Assign a code
-   at the validation site using this bounded vocabulary:
-   - `loading_disabled`, `checkpoint_missing`, `checkpoint_path_invalid`,
-     `checkpoint_read_failed`, and `checkpoint_decode_failed`;
-   - `workspace_schema_incompatible` and `identity_mismatch`;
-   - `stage_mismatch`, `step_mismatch`, `lane_mismatch`, `module_mismatch`, and
-     `status_not_reusable`;
-   - `dependency_mismatch` for the `dependency_invalidated` category;
-   - `artifact_payload_invalid`, `artifact_digest_mismatch`,
-     `artifact_codec_incompatible`, and `artifact_not_canonical`; and
-   - `checkpoint_reused` and `accepted_artifact_reused` for successful reuse,
-     and `recompute_step` for forced execution.
-   Retain an existing code not listed here only when a current external or
-   documented contract already depends on it.
-3. Keep detail human-readable, UTF-8, bounded, and sanitized through one helper.
-   Detail may identify stage, step, lane, module, expected status, or schema
-   version, but must not include artifact/reference content, source content,
-   credentials, environment values, or local paths. Tests must assert codes and
-   safety properties, not exact detail prose.
-4. Change the centralized runner decision flow from Stage 1 so the final loader
-   or canonical-validation decision is recorded before returning a
-   required-predecessor error. The contextual error must identify the step and
-   lane and include the stable reason code; it must not interpolate unsafe
-   loader detail.
-5. Propagate typed values without lossy conversion through checkpoint events,
-   run manifests, debug summaries, and CLI diagnostics. Convert to strings only
-   at existing serialized boundaries unless changing an internal field type is
-   simpler and wire-compatible.
-6. Update the canonical current-behavior owners in the same change:
-   `docs/internal/state.md` owns the internal decision flow, while
-   `docs/operations.md` owns operator diagnosis and any operator-visible reason
-   code table. Link rather than duplicate the table elsewhere.
+- Introduce a small provider-adapter-owned profile inspection or validation
+  function in `internal/framework/llm`. Its public internal signature must use
+  Notarius-owned configuration and result/error types rather than returning
+  PromptKit types to the CLI.
+- Share the code that applies `profile_dir`, `profile_file`, and registered
+  backend options between the production PromptKit engine and the inspection
+  engine. Preserve the mutual-exclusion and local-backend rules.
+- Change CLI explicit-profile preflight to use `Engine.InspectProfile` through
+  that LLM boundary.
+- Remove `profileCheckPromptID`, `profileCheckPromptFS`, the `testing/fstest`
+  production dependency, and the synthetic `Prepare` request.
+- Preserve distinct, useful errors for an absent profile, invalid profile,
+  unknown backend registration, cancellation, and invalid profile source.
+- Do not require `api_key_env` to be populated during configuration validation.
+  Inspection may report credential requirements internally, but actual
+  preparation remains responsible for credential availability before a model
+  call.
+- Update current-behavior sections in `docs/internal/cli.md` and
+  `docs/internal/llm.md`. Keep field definitions in `docs/config.md`.
 
-### Tests
+### Tests And Validation
 
-- Add a table in `internal/framework/checkpoint` that exercises one
-  representative input per reason-code family and asserts category, code,
-  bounded valid UTF-8 detail, and absence of supplied secret/path sentinels.
-- Add pipeline behavior tests proving a required-predecessor failure records the
-  underlying missing, corrupt, incompatible, or dependency-invalidated
-  decision before returning.
-- Retain focused manifest/debug serialization assertions for category and code;
-  do not add exact-detail or full-manifest snapshots.
+- Replace synthetic-prompt tests with profile inspection tests covering:
+  configured local backend success; missing local backend failure; absent
+  profile; malformed profile; and an otherwise valid profile whose credential
+  environment variable is intentionally unset.
+- Prove validation performs no provider HTTP call and remains offline.
+- Run `go test ./internal/framework/llm ./internal/cli` and `go test ./...`.
+- Run `git diff --check`.
 
-### Completion Gate
+### Completion Criteria
 
-Run `go test ./internal/framework/checkpoint ./internal/framework/pipeline
-./internal/core/artifacts ./internal/core/debugbundle ./internal/cli`. Search the
-production checkpoint package to confirm no decision category or reason code is
-derived from diagnostic prose.
+- No production synthetic profile-check prompt remains.
+- Profile validation uses the same ordinary profile source and backend
+  registrations as execution.
+- Configuration validation succeeds for structurally valid profiles without
+  reading credential values.
 
-## Stage 3: Hydrate Required Predecessors From Accepted Normalized Artifacts
+## Stage 4: Add Application Fallback Profile Asset Plumbing
 
-### Objective
+### Goal
 
-Make selective recomputation enforce the lane-level accepted-artifact contract:
-a valid normalized producer artifact is sufficient even when its extract or
-merge stage cache is unavailable.
+Allow module families to register application-owned fallback profile YAML
+without placing domain policy in generic LLM code.
 
-### Changes
+### Work
 
-1. Extend the checkpoint loader contract with a dedicated accepted-normalized-
-   artifact lookup. Implement it in the filesystem loader and every no-op or
-   test implementation. The lookup receives step ID, lane ID, and normalizer
-   module key and returns the normalized artifact, its warnings, and an explicit
-   checkpoint decision. It must not require caller-supplied extract or merge
-   dependency fingerprints.
-2. The filesystem lookup may reuse the existing normalize manifest and payload;
-   do not add a second persistent copy. It is reusable only when all of the
-   following hold:
-   - workspace schema is v3 and the non-empty stored checkpoint identity matches
-     the current invocation identity;
-   - stage, step, lane, normalizer module, and successful status match;
-   - the manifest output digest matches the payload; and
-   - the payload can subsequently be validated through the registered artifact
-     codec.
-   Skipping caller-supplied merge dependencies is safe only because the matched
-   non-empty checkpoint identity already binds the current input, resolved
-   topology and configuration, external references, runtime overrides, LLM
-   profiles, and component semantic fingerprints. Do not weaken or omit that
-   identity check.
-   A loader lacking a verifiable current identity must return an unavailable
-   decision rather than perform accepted-artifact reuse.
-3. Add a pipeline hydration helper that decodes the returned serialized
-   artifact through the producer's registered codec, re-encodes it canonically,
-   and requires exact artifact kind, schema ID/name/version/digest, media type,
-   content bytes, and content digest. Return a runner-owned clone with producer
-   step, lane, module, and source identity. Any mismatch is an explicit bounded
-   decision and the bytes never reach a consumer.
-4. Before normal execution of a lane marked in `RequireReusableLanes`, use the
-   accepted-artifact lookup:
-   - on success, mark the lane terminal without invoking extract, merge,
-     normalize, or their validators;
-   - append the accepted normalized output in the normal deterministic location
-     and restore only the warnings stored with that normalized checkpoint;
-   - record one `reused` normalize decision with a stable accepted-output reuse
-     reason code; do not synthesize extract/merge decisions, warnings, or
-     rejections that were not loaded; and
-   - allow the ordinary step barrier and generated handoff code to consume that
-     output exactly as it consumes a freshly executed output.
-5. On missing, rejected, corrupt, non-canonical, or incompatible accepted state,
-   record the decision and fail the run before the dependent step begins. Do
-   not fall back to stage execution. Forced lanes must bypass this hydration
-   path and execute normally.
-6. Leave ordinary resume unchanged when no lane is marked
-   `RequireReusableLanes`: it may reuse or recompute extract, merge, and
-   normalize progressively under the existing cold-miss rules.
-7. Keep generated-reference fingerprints and provenance unchanged. Hydrating a
-   byte-identical producer must yield the same canonical handoff digest and
-   downstream dependency fingerprint as fresh execution.
-8. Update `docs/internal/pipeline.md`, `docs/internal/state.md`, and
-   `docs/operations.md` in this stage to distinguish progressive stage reuse
-   from accepted normalized-artifact hydration and to document the fail-rather-
-   than-rerun rule for invalid required predecessors.
+- Extend `internal/framework/llm.AssetRegistry` with a separate fallback
+  profile source collection, registration method, flattened filesystem, and
+  safe content digest.
+- Reuse the existing asset-source path validation and flattening behavior where
+  appropriate. Reject invalid roots, unreadable assets, and duplicate flattened
+  paths. Do not parse PromptKit profile YAML in Notarius.
+- Add `promptkit.WithFallbackProfileFS` to production engine options only when
+  at least one fallback profile source is registered.
+- Supply the identical assembled fallback source to the profile-inspection
+  engine. Adjust CLI composition so pipeline-aware profile validation can use
+  the production LLM asset registry without exposing PromptKit types.
+- Extend profile-source checkpoint identity to include the exact fallback
+  profile asset digest in addition to the PromptKit catalog marker and operator
+  source. Keep the resulting fingerprint hash-only and path/content/credential
+  free.
+- Keep operator source precedence owned by PromptKit. Do not implement profile
+  merging or duplicate PromptKit source resolution in Notarius.
+- Update `docs/internal/llm.md` only for the new implemented generic asset and
+  fingerprint mechanics. No domain fallback exists until Stage 5.
 
-### Tests
+### Tests And Validation
 
-- At the pipeline/checkpoint boundary, create a valid producer normalize
-  checkpoint while omitting or corrupting its extract and merge checkpoints.
-  Select a later step for recomputation and prove the producer hydrates, no
-  producer operation or validator runs, and the dependent receives the exact
-  canonical artifact.
-- Cover missing, rejected-status, corrupt, non-canonical, wrong-codec-identity,
-  and wrong-content-digest normalize state. Assert failure and the recorded
-  stable decision before any consumer invocation.
-- Prove forced producers execute instead of hydrating, while a reusable
-  predecessor and an unrelated lane remain reusable.
-- Prove fresh and hydrated producer outputs create identical generated
-  provenance and downstream checkpoint fingerprints without exposing content
-  or paths.
+- Add focused AssetRegistry tests for successful flattening, invalid roots,
+  duplicate paths, and hash changes when fallback bytes change.
+- Add adapter-level tests showing that the fallback filesystem reaches both
+  execution construction and inspection construction.
+- Extend checkpoint tests to prove fallback content changes profile-source
+  identity without exposing raw YAML or paths. Use relational comparisons, not
+  a fixed hash literal.
+- Run `go test ./internal/framework/llm ./internal/cli` and `go test ./...`.
+- Run `git diff --check`.
 
-### Completion Gate
+### Completion Criteria
 
-Run `go test ./internal/framework/checkpoint ./internal/framework/pipeline
-./internal/modules/integration` and the corresponding race tests. Manually
-inspect one failed test fixture to confirm the accepted artifact remains on
-disk but its bytes do not appear in the manifest, decision detail, debug
-summary, or error.
+- Generic plumbing can carry application fallback profiles while remaining
+  unaware of D&D IDs or model settings.
+- Inspection, execution, and checkpoint identity use the same fallback asset
+  source.
 
-## Stage 4: Complete Recompute CLI And Recovery Acceptance Coverage
+## Stage 5: Adopt The D&D `dnd-extraction` Fallback
 
-### Objective
+### Goal
 
-Exercise the operator-visible recomputation contract through stable boundaries
-and close the acceptance-test omissions from the original plan.
+Give the D&D module family one stable embedded workload profile that operators
+can replace.
 
-### Changes
+### Work
 
-1. Add one table-driven CLI contract test for `--recompute-step` covering:
-   - a valid explicit step and the implicit `default` step;
-   - repeated flags and an empty or unknown step ID;
-   - use without `--resume`;
-   - use when checkpoint recording is disabled; and
-   - combination with `--only`.
-   Assert exit classification and stable identifying fragments or reason codes,
-   not complete prose.
-2. Add one filesystem-backed CLI execution test using deterministic fake
-   modules and a three-step generated dependency chain plus one unrelated lane:
-   - perform a fresh checkpointed run;
-   - remove or corrupt only the required producer's extract and merge state
-     inside `t.TempDir()`, leaving its normalize artifact valid;
-   - resume with the middle step selected;
-   - assert the selected lane and transitive dependents execute, the predecessor
-     hydrates without module calls, the unrelated lane reuses, and output and
-     decision ordering are deterministic; and
-   - invalidate the producer normalize state in a subcase and assert the command
-     fails before dependent execution with the bounded decision preserved.
-3. Add or extend one generic two-step pipeline test proving handoff succeeds
-   both from fresh producer execution and from accepted normalized-artifact
-   hydration. Keep this at the pipeline boundary if the CLI execution test
-   already proves flag wiring; do not duplicate every CLI case end to end.
-4. Review existing recomputation policy tests. Retain the pure closure test
-   because it protects transitive selection, but remove or consolidate any new
-   test that merely repeats the CLI or pipeline behavior above.
-5. Make only production changes revealed as necessary by these contract tests;
-   do not add new flag semantics or broaden the feature roadmap.
+- Add a D&D-owned embedded PromptKit profile asset with ID `dnd-extraction`
+  under `internal/modules/dnd`. Use the exact baseline defined in
+  `promptkit.md`: OpenRouter, `openai/gpt-5.6-luna`, no explicit reasoning
+  effort, a 240-second timeout, flex service tier, and no selected temperature,
+  token limit, or `top_p`. The omitted reasoning value intentionally allows
+  OpenAI's backend to apply its `medium` default.
+- Register the profile filesystem from the D&D registrar through the generic
+  fallback profile asset boundary. Keep D&D policy out of
+  `internal/framework/llm` and the CLI composition root.
+- Change every maintained D&D LLM prompt definition—including scene chunking,
+  all D&D extractors, and NPC normalization—from the model-named default to
+  `default_profile: dnd-extraction`.
+- Add an integration-level profile-resolution test proving that:
+  - the fallback resolves when no operator source defines the ID;
+  - a valid operator profile with the same ID wins completely; and
+  - an invalid matching operator profile fails rather than falling through.
+- Test through Notarius's assembled production assets and PromptKit boundary;
+  do not duplicate every upstream source-precedence case.
+- Update the implemented profile ownership and prompt-default behavior in
+  `docs/internal/dnd.md`, `docs/internal/llm.md`, and
+  `docs/integrations/pkg-promptkit.md`. Defer the complete operator walkthrough
+  and examples to Stage 10.
 
-### Completion Gate
+### Tests And Validation
 
-Run `go test ./internal/cli ./internal/framework/pipeline
-./internal/framework/checkpoint`, then run the CLI, pipeline, and checkpoint
-packages under the race detector. Confirm no test asserts internal loader call
-counts, exact decision detail, filesystem layout outside a temp workspace, or
-the exact length of any prompt or prefix.
+- Run focused D&D prompt preparation tests and the production composition
+  tests.
+- Run `go test ./internal/modules/dnd/... ./internal/framework/llm
+  ./internal/cli`.
+- Run `go test ./...`.
+- Verify `rg -n 'default_profile: gemini-2-flash' internal/modules/dnd`
+  returns no matches.
+- Run `git diff --check`.
 
-## Stage 5: Current Documentation And Release Verification
+### Completion Criteria
 
-### Objective
+- All maintained D&D prompts use the application-owned logical profile ID.
+- The fallback works without an operator profile and remains authoritatively
+  overridable by a matching valid operator definition.
 
-Reconcile all canonical documentation after the staged changes and verify the
-complete feature against policy and roadmap.
+## Stage 6: Introduce Module Execution-Class Metadata
 
-### Changes
+### Goal
 
-1. Re-read `docs/internal/pipeline.md`, `docs/internal/state.md`,
-   `docs/operations.md`, and `docs/cli.md` against the final code. Correct any
-   stale statements left by Stages 1 through 4 without duplicating their
-   canonical contracts.
-2. Ensure internal documentation describes the coordinator, lane engine, stage
-   checkpoint flow, and accepted-artifact validation at the responsibility
-   level without listing volatile private helper names.
-3. Confirm the operator-visible reason-code table has one canonical owner and
-   other documents link to it rather than maintaining parallel copies.
-4. Remove stale implementation claims exposed by this work and ensure the
-   feature roadmap continues to describe target policy rather than task
-   sequencing.
+Make each production module's ability to use an LLM statically discoverable
+without yet changing profile inheritance.
 
-### Verification
+### Work
 
-Run the repository-prescribed commands from `docs/development.md`:
+- Add `ExecutionClass contracts.ExecutionClass` to `pipeline.ModuleSpec` and
+  preserve it through normalization, cloning, catalogs, registries, JSON/debug
+  views, and lookup helpers.
+- In this transitional stage only, allow an omitted execution class to
+  normalize to deterministic so existing test-only fixtures can be migrated in
+  Stage 7 without breaking the repository midway.
+- Explicitly classify every production module:
+  - D&D scene chunking, every D&D extractor, and D&D NPC normalization as
+    `llm_backed`;
+  - all other current production input, chunk, merge, normalize, and output
+    modules as `deterministic`.
+- Update production module specification tests and production catalog tests to
+  assert the semantic class alongside stage, artifact kind, and capabilities.
+- Add catalog lookup support needed by later resolution to retrieve a selected
+  module's execution class by stage and key without constructing it.
+- Do not implement pipeline-level profile inheritance or reject deterministic
+  profiles yet.
+- Update `docs/internal/modules.md` and `docs/internal/dnd.md` to identify
+  execution class as registered module metadata, while noting only implemented
+  uses.
+
+### Tests And Validation
+
+- Run module registration/spec tests across generic, Seriatim, and D&D
+  families.
+- Run `go test ./internal/framework/pipeline ./internal/modules/...`.
+- Run `go test ./...` and `git diff --check`.
+
+### Completion Criteria
+
+- Every production module has an explicit correct execution class.
+- Catalog consumers can retrieve that class without a concrete module
+  instance.
+- Test-only omitted classes remain the only temporary compatibility behavior.
+
+## Stage 7: Enforce Execution Metadata And Remove Runtime Probing
+
+### Goal
+
+Finish the execution-class contract so missing metadata cannot cause future
+profile drift.
+
+### Work
+
+- Update every framework, CLI, and integration test module specification to
+  declare an explicit execution class appropriate to the fake behavior.
+- Change module-spec validation so an empty or unsupported execution class is a
+  registration error. Remove the transitional deterministic default from
+  Stage 6.
+- Replace the chunk runner's special `ChunkExecutionClassProvider` probe with
+  specification-derived behavior. Remove the now-redundant provider interface,
+  implementation methods, and tests when they have no remaining consumer.
+- Ensure chunk producer provenance remains unchanged: it records a non-empty
+  effective binding profile for an LLM-backed chunker, while a deterministic
+  chunker records no profile. A profile selected only through the prompt
+  default remains represented by PromptKit's actual-profile manifest rather
+  than being invented as an explicit chunk binding.
+- Review helper constructors and fixtures for opportunities to set execution
+  class once without obscuring the class under test. Do not introduce an
+  elaborate test-spec framework.
+- Update internal documentation if the removal changes any described runtime
+  mechanics.
+
+### Tests And Validation
+
+- Add or retain focused registration tests for missing and invalid execution
+  classes.
+- Retain chunk-plan provenance tests for LLM-backed and deterministic
+  chunkers.
+- Run `go test ./internal/framework/pipeline ./internal/modules/...`.
+- Run `go test ./...`, `go vet ./...`, and `git diff --check`.
+
+### Completion Criteria
+
+- No registered module specification relies on an implicit execution class.
+- Pipeline metadata, not a concrete runtime type assertion, owns module
+  execution classification.
+
+## Stage 8: Resolve Programmatic Pipeline Profile Defaults
+
+### Goal
+
+Implement profile inheritance and precedence inside the pipeline resolver
+before exposing the field through YAML configuration.
+
+### Work
+
+- Add an optional trimmed `LLMProfile` field to
+  `pipeline.PipelineProfile`. Add a non-empty runtime override field to
+  `pipeline.ResolveOptions` so all precedence decisions occur in the resolver
+  rather than through pre-resolution mutation.
+- After module selection, `--only` filtering, default validator-chain
+  selection, and validator compatibility resolution, apply effective profiles
+  to every selected input, chunk, extract, merge, normalize, output, and
+  validator binding according to the precedence in `promptkit.md`.
+- Apply profiles only when the selected module or validator execution class is
+  `llm_backed`.
+- Reject a binding-specific `llm_profile` on any deterministic module or
+  validator. Do not reject or inspect an unused pipeline default when no
+  selected LLM-backed binding consumes it.
+- Leave an LLM-backed binding empty when no CLI, binding, or pipeline profile is
+  selected so PromptKit can use the prompt's `default_profile`.
+- Store the effective values on resolved bindings before digest construction.
+  Do not add a second inheritance decision to execution.
+- Ensure semantically equivalent repeated binding profiles and one inherited
+  default produce the same resolved pipeline digest. Ensure any changed
+  effective profile changes the digest.
+- Do not modify file configuration or CLI parsing in this stage.
+
+### Tests And Validation
+
+- Add pipeline package tests for the complete precedence matrix:
+  runtime override; binding-specific exception; pipeline default; prompt
+  fallback; and deterministic bindings.
+- Cover default and explicitly configured validator chains, all relevant stage
+  categories, `--only` lane selection, unused defaults, deterministic-profile
+  rejection, and semantic digest equivalence.
+- Prefer table-driven package-level tests over assertions on private traversal
+  helpers.
+- Run `go test ./internal/framework/pipeline` and `go test ./...`.
+- Run `git diff --check`.
+
+### Completion Criteria
+
+- Programmatic pipelines resolve one canonical effective profile policy.
+- Only LLM-backed resolved bindings can contain a profile.
+- Runtime override, binding, pipeline, and prompt precedence is unambiguous and
+  digest-stable.
+
+## Stage 9: Expose Pipeline Defaults Through Configuration And CLI
+
+### Goal
+
+Make the profile-default workflow available to operators while preserving
+validation and override behavior.
+
+### Work
+
+- Add optional `pipelines.<id>.llm_profile` support to the version 4 file
+  configuration model. Use presence-aware decoding so an explicitly set blank
+  value is rejected, while omission remains valid.
+- Preserve the field through file application, configuration cloning,
+  effective configuration, and programmatic profile copies without aliasing or
+  trimming drift.
+- Remove `applyLLMProfileOverride`. Pass the CLI override through the resolver's
+  runtime-override input so deterministic bindings are never populated.
+- Update effective profile-ID collection to cover every selected LLM-backed
+  module stage and LLM-backed validator, including future LLM-backed input and
+  output modules. Do not inspect deterministic or unselected profiles.
+- Ensure `run`, `config validate --pipeline`, resume/checkpoint identity, and
+  relevant dry preflight paths all use the same resolved effective profiles.
+- Preserve `--llm-profile` as the highest-precedence non-empty run-wide
+  override and preserve binding-specific profiles as exceptions when no CLI
+  override is present.
+- Do not increment the configuration version.
+- Update current configuration and CLI contracts in `docs/config.md` and
+  `docs/cli.md` in the same stage. Link to operations for the deployment
+  workflow rather than duplicating it prematurely.
+
+### Tests And Validation
+
+- Add file-config tests for omission, trimming, explicit blank rejection,
+  unknown-key behavior, cloning, and round-trip application.
+- Add effective-config and CLI contract tests for precedence, LLM-only
+  application, inherited-profile inspection failure before factory execution,
+  `--only`, and digest changes.
+- Retain offline operation and do not require credentials for
+  `config validate --pipeline`.
+- Run `go test ./internal/core/config ./internal/framework/pipeline
+  ./internal/cli`.
+- Run `go test ./...`, `go vet ./...`, and `git diff --check`.
+
+### Completion Criteria
+
+- Operators can select `dnd-extraction` once per pipeline.
+- Configuration and CLI paths share the resolver's precedence policy.
+- Unknown effective profiles fail preflight, while deterministic and unused
+  profiles do not cause spurious inspection.
+
+## Stage 10: Complete Operator Documentation, Examples, And Decision Record
+
+### Goal
+
+Make the implemented workflow understandable, copyable, and maintainable
+without duplicating canonical facts.
+
+### Work
+
+- Create an ADR using the next sequential number for the durable decision to
+  use workload-oriented pipeline defaults with operator-overridable application
+  fallback profiles. Record context, decision, alternatives, and consequences;
+  do not turn the ADR into a field reference or implementation log.
+- Complete `docs/config.md` as the canonical owner of profile-source fields,
+  `pipelines.<id>.llm_profile`, validation, and precedence.
+- Complete `docs/operations.md` with an operator workflow that distinguishes
+  Notarius embedded prompts, Notarius fallback profiles, PromptKit built-ins,
+  and deployment filesystem profiles. Include production/development/local use
+  of the same `dnd-extraction` ID, credential handling, absolute-path guidance,
+  and the fact that current relative profile paths use the process working
+  directory rather than the configuration file's directory.
+- Complete `docs/integrations/pkg-promptkit.md` with the v0.5.0 boundary,
+  prepared execution, inspection, fallback and ordinary source precedence,
+  optional provider controls, capacity adaptation, and compatibility policy.
+- Update `docs/internal/configuration.md`, `docs/internal/pipeline.md`,
+  `docs/internal/cli.md`, `docs/internal/llm.md`, `docs/internal/modules.md`, and
+  `docs/internal/dnd.md` only for their owned implementation details. Link to
+  canonical configuration, operations, and upstream format contracts rather
+  than restating them.
+- Keep exactly the existing two D&D configuration examples. Add
+  `llm_profile: dnd-extraction` to the minimal and complete pipelines and remove
+  the now-redundant model-named binding override from the complete example.
+- Add one secret-free maintained operator profile at
+  `examples/profiles/dnd-extraction.yml`. It should be a complete valid profile
+  for the same logical ID and may mirror the embedded baseline; its purpose is
+  to demonstrate file ownership and format, not claim automatic environment
+  detection. Link it from the configuration and operations documentation.
+- If the complete example selects the external profile file, use a path that
+  is valid for the documented repository-root invocation and explicitly note
+  the working-directory rule. Keep the minimal example dependent only on the
+  embedded fallback.
+- Add or extend maintained-example validation so both configuration examples
+  and the profile YAML are checked without generation or credentials.
+- Remove the now-implemented `Pipeline-Level LLM Profile Defaults` section from
+  `docs/roadmap/future.md`. Preserve the unrelated deterministic session and
+  concurrency items.
+- Do not delete `promptkit.md` or this implementation plan during the feature
+  implementation; retire them only after post-implementation review.
+
+### Tests And Validation
+
+- Run maintained example/configuration tests and relevant CLI help/parser
+  tests.
+- Run `go test ./...`.
+- Run `rg -n 'gemini-2-flash' examples docs` and review every remaining match
+  for intentional model-policy or historical context.
+- Run `rg -n 'v0\.3\.0|profileCheckPrompt|applyLLMProfileOverride' .` and resolve
+  stale production or current-documentation matches.
+- Verify all new links and `git diff --check`.
+
+### Completion Criteria
+
+- Every current fact has one canonical documentation owner.
+- Operators can distinguish and deploy all profile layers without reading Go
+  source.
+- Both maintained configurations and the maintained external profile are valid,
+  secret-free, and tested offline.
+- Implemented profile work no longer remains in `future.md`.
+
+## Stage 11: Final Verification And Quality Review
+
+### Goal
+
+Verify the complete migration as one integrated change and correct only defects
+or omissions found during that review.

+### Work
+
+- Review the final diff against every acceptance criterion in `promptkit.md`.
+- Confirm provider-specific PromptKit types remain inside the LLM integration
+  boundary and D&D policy remains inside the D&D module family.
+- Confirm execution and inspection receive identical ordinary, fallback, and
+  backend configuration.
+- Confirm no paths, profile YAML, endpoints, credentials, or prepared handle
+  state leak into fingerprints or ordinary diagnostics.
+- Confirm all production module specs have explicit correct execution classes
+  and every resolved deterministic binding is profile-free.
+- Confirm prompt default, pipeline default, binding override, and CLI override
+  behavior through representative assembled configurations.
+- Review tests for redundancy and remove obsolete synthetic-prompt,
+  runtime-probe, exact-hash, or duplicated upstream-behavior tests superseded by
+  stronger contract tests.
+- Perform an optional manual D&D quality comparison if credentials and an
+  evaluation transcript are deliberately supplied. Record no private input or
+  credential material, and do not make this comparison a completion gate.
+
+### Validation Commands
 
 ```sh
+gofmt -w <changed-go-files>
 go test ./...
+go test -race ./internal/framework/llm ./internal/core/config ./internal/framework/pipeline ./internal/cli
 go vet ./...
 go build ./cmd/notarius
+git diff --check
 ```
 
-Also run race tests for the pipeline, checkpoint, CLI state, D&D NPC registry,
-and D&D integration packages. Validate maintained examples/configurations
-through the production catalog. Review one fresh run, ordinary resumed run,
-forced-recompute run, hydrated-predecessor run, and invalid-predecessor failure
-for deterministic ordering, correct decisions, bounded provenance, and absence
-of generated content, secrets, or local paths in manifests and diagnostics.
+Also run focused stale-contract searches:
 
-### Completion Gate
+```sh
+rg -n 'gitea.maximumdirect.net/eric/promptkit v0\.3\.0|PromptKit v0\.3\.0' .
+rg -n 'default_profile: gemini-2-flash|profileCheckPrompt|applyLLMProfileOverride' internal docs examples
+```
 
-The follow-up is complete only when every finding summarized above is protected
-by a stable behavioral test, the current documentation matches the corrected
-implementation, the full verification suite passes, and the worktree contains
-no temporary adapters or TODOs introduced by these stages.
+Review any matches rather than deleting intentional historical references
+blindly.
+
+### Completion Criteria
+
+- All automated checks pass offline and without real credentials.
+- The implemented behavior matches `promptkit.md` with no known architecture,
+  provenance, checkpoint, profile-precedence, or documentation gap.
+- Any optional live evaluation is clearly separate from correctness testing.
 
 ## Open Questions
 
-None. The feature roadmap and this plan fix the required product and
-architecture choices. If implementation reveals that accepted normalized
-artifacts cannot be validated safely without a persistent format change, stop
-and amend this plan rather than weakening identity, codec, or content
-validation.
+None. The roadmap decisions are sufficient to implement every stage without an
+additional product or architecture choice.

-# Scope: Ordered Pipeline Steps
-
-## Status
-
-Implemented. This document preserves the bounded feature policy, architecture
-choices, acceptance criteria, and exclusions. Current behavior belongs in the
-canonical [CLI](../cli.md), [Configuration](../config.md),
-[Operations](../operations.md), and [internal pipeline](../internal/pipeline.md)
-documentation rather than in this roadmap.
-
-## Policy Recommendation
-
-Treat ordered pipeline steps, generated artifact references, and
-dependency-aware checkpoint reuse as one coherent platform capability. The D&D
-proving workflow produces accepted normalized NPC output first and then supplies
-it to spell extraction, combat-turn extraction, and combat-turn normalization.
-
-## Intended Outcome
-
-A configured pipeline may contain multiple ordered steps while retaining one
-pipeline-wide input, chunk plan, output, worker budget, LLM scheduler, run
-manifest, and failure boundary. Every artifact lane still follows the fixed
-extract, validate, merge, validate, normalize, and validate lifecycle. Steps
-add explicit barriers between groups of lanes; they do not create arbitrary
-stage graphs.
-
-An accepted normalized artifact from an earlier step may be bound explicitly
-to declared reference slots in a later step. The framework remains
-domain-neutral, and generated references remain contextual material rather than
-source evidence.
-
-## Fixed Product And Architecture Decisions
-
-### Pipeline shape
-
-- Input parsing and chunk planning remain pipeline-wide and execute once.
-- A step contains one or more artifact lanes. Step order is configuration order.
-- Lanes within a step remain independent and may use the existing bounded
-  concurrency model.
-- A later step cannot begin until every lane in the current step is terminal
-  and every generated artifact it requires is accepted and available.
-- Public artifact and failure ordering is step order followed by deterministic
-  lane and source-chunk order, never completion order.
-- Output encoding occurs once, after every step succeeds.
-- This is not an arbitrary DAG, a general workflow language, concurrent
-  cross-lane reconciliation, or permission for modules to invoke other modules.
-
-### Configuration model
-
-Existing single-step pipelines remain valid. A top-level `artifacts` map is
-treated as an implicit step with stable ID `default`. A pipeline may configure
-either `artifacts` or `steps`, but not both. Explicit steps must be non-empty
-and have unique, trimmed, non-empty IDs. Artifact lane IDs must remain unique
-across the entire pipeline so output paths, selectors, manifests, errors, and
-checkpoint scopes remain unambiguous.
-
-The target configuration shape is:
-
-```yaml
-pipelines:
-  dnd-session:
-    input: seriatim
-    chunk: generic
-    steps:
-      - id: identify-npcs
-        artifacts:
-          npcs:
-            extract: dnd/npcs
-            normalize: dnd/npcs
-      - id: grounded-events
-        references:
-          npcs:
-            artifact:
-              step: identify-npcs
-              lane: npcs
-        artifacts:
-          spells:
-            extract: dnd/spells
-            normalize: dnd/spells
-          combat:
-            extract: dnd/combat-turns
-            normalize: dnd/combat-turns
-    output: json
-```
-
-Existing scalar reference values continue to represent external file paths.
-The structured `artifact` form identifies accepted normalized output from one
-earlier step and lane. Generated artifact bindings are allowed at step scope or
-at an individual module target; they are not inferred from module keys, lane
-names, slot names, or domain knowledge.
-
-A step-scoped reference applies automatically to every selected target in that
-step that declares the slot. In the example, one `npcs` binding reaches the
-spell extractor plus the combat extractor and normalizer. A target-local
-binding is used when only one module should consume the artifact.
-
-Pipeline-level external references remain defaults. Step-local external
-references override pipeline-level external defaults, and target-local
-external references retain their existing precedence. A generated reference
-and an external reference may not resolve to the same effective target slot;
-configuration or a runtime override that creates that conflict is invalid.
-Likewise, a step-scoped and target-local generated binding cannot both target
-the same effective slot.
-
-Each effective target slot accepts at most one producer. One producer may fan
-out to multiple compatible slots in a later step. Aggregating several producer
-artifacts into one slot is outside this scope.
-
-Reference-slot specs gain optional generated-artifact compatibility metadata.
-A generated binding is allowed only when the consumer slot declares the
-producer's artifact kind; the producer's registered codec supplies the exact
-schema identity and media type used for the handoff. The D&D `npcs` consumer
-slots declare the normalized NPC-list artifact kind. Existing external-file
-slots and bindings retain their current behavior and do not acquire an artifact
-kind merely because their bytes happen to decode as one.
-
-### Resolution and preparation
-
-Resolution validates the complete ordered structure before source processing.
-It must reject duplicate identities, missing producers, same-step or forward
-references, undeclared slots, reference conflicts, and incompatible artifact
-kind, schema, media type, or cardinality constraints that are statically
-discoverable. Size is checked when canonical producer bytes exist at handoff.
-Ordered steps make cycles structurally impossible; resolution must not
-introduce a general graph scheduler to rediscover their order.
-
-The resolved pipeline and its digest include step order, step IDs, lane
-membership, generated-reference topology, producer identity, consumer targets,
-and existing module and validator policy. Cloning, redaction, canonical JSON,
-debug summaries, and manifests preserve the same structure without reference
-content or secrets.
-
-All modules and validators are still selected, option-validated, and
-constructed before source parsing. Generated content cannot be supplied during
-construction because it does not exist yet. The framework therefore augments
-the existing operation-request `References` at the step boundary. Consumers
-that currently assume an NPC registry is construction-only must accept the
-generated registry from their operation request without deferring general
-module construction until after upstream work.
-
-Only validation that inherently depends on generated bytes may occur at the
-handoff. A handoff validation failure is a contextual framework error and fails
-the run before any consumer in that step begins.
-
-### Generated artifact handoff
-
-Only accepted normalized output may cross a step boundary. Raw extraction
-responses, rejected artifacts, merge intermediates, and validator diagnostics
-cannot be bound as references.
-
-The framework serializes the producer through its registered canonical artifact
-codec and constructs one immutable reference item containing:
-
-- the declared target slot;
-- canonical artifact bytes and media type;
-- artifact kind and schema ID, name, version, and schema digest;
-- canonical content digest and size; and
-- producer pipeline, step, lane, and module provenance.
-
-A generated binding requires exactly one accepted normalized artifact from its
-producer lane. No artifact is a missing dependency, while more than one is a
-cardinality error; a typed collection such as an NPC list remains one artifact.
-Combining several normalized outputs into one reference is aggregation and is
-outside this scope.
-
-The existing slot contract remains authoritative for accepted media types,
-maximum size, and cardinality. Generated content is cloned at ownership
-boundaries and never exposed through a filesystem path. Manifests and debug
-summaries record identities and bounded provenance, not artifact content.
-
-Configuring a generated binding makes that dependency required even when the
-consumer module declares the underlying slot optional. An accepted artifact
-whose domain collection is empty is still a valid artifact and may be handed
-off. If the producer has no accepted normalized artifact, the entire run fails
-with a deterministic dependency error and no later step begins.
-
-### Checkpoint reuse and selective recomputation
-
-Generated references participate in downstream checkpoint dependencies by
-artifact kind, complete schema identity, media type, and canonical content
-digest. The pipeline digest protects topology; stage dependency fingerprints
-protect the exact upstream artifact consumed. The runner must never combine a
-new or changed producer with stale dependent output.
-
-Ordinary resume may progressively decode compatible producer and consumer stage
-checkpoints through the registered codec. Selective recomputation may hydrate a
-required unselected producer directly from its accepted normalized artifact;
-its extract and merge state are not prerequisites. Missing, rejected, corrupt,
-incompatible, or changed accepted state stops the run before dependent
-execution rather than implicitly rerunning the producer. Independent work
-remains reusable.
-
-The operator control `--recompute-step <step-id>` has these semantics:
-
-- it requires checkpoint recording and `--resume`;
-- the selected step and all transitive dependents execute rather than reuse
-  their checkpoints;
-- valid required predecessors and unrelated work remain reusable;
-- the recompute selection affects loader decisions, not the persistent
-  checkpoint identity of otherwise identical work; and
-- the command fails before dependent execution if a required predecessor has
-  no reusable accepted artifact.
-
-Existing `--only` behavior remains unchanged for implicit single-step
-pipelines. Combining `--only` with explicit multi-step pipelines is outside
-this scope and should be rejected with actionable guidance rather than given
-implicit dependency-expansion semantics.
-
-Checkpoint events, manifests, and diagnostics distinguish executed, reused,
-forced-recomputed, and dependency-invalidated work. Invalidation reasons are
-bounded, deterministic, and free of reference content, local paths, or secrets.
-Old checkpoint state need not be migrated; it must produce a safe, explicit
-cold miss rather than an error or unsafe reuse.
-
-### Failure, cancellation, and concurrency
-
-The existing run-wide worker and provider-call limits apply across every step.
-Workers may be reused between steps, but concurrency cannot cross a step
-barrier. A framework error cancels started work using the existing bounded
-drain behavior and prevents later steps and output encoding. Rejections remain
-recorded outcomes, but failure to produce a normalized artifact required by a
-generated binding escalates to the run-level dependency error described above.
-
-The failed manifest retains completed upstream outcomes, step and lane
-provenance, rejections, checkpoint events, and the dependency failure without
-embedding generated artifact content.
-
-## D&D Proving Workflow
-
-The production acceptance workflow has two explicit steps:
-
-1. `identify-npcs` runs the NPC lane through normalization and its complete
-   validator policy.
-2. `grounded-events` receives the canonical NPC artifact in its step-scoped
-   `npcs` reference and runs spell and combat-turn lanes. The binding reaches
-   spell extraction, combat-turn extraction, and combat-turn normalization.
-
-Spell and combat-turn lanes may execute concurrently after the handoff. NPC
-content may ground names and identities but cannot establish a spell cast or
-combat event; source units remain the only event evidence.
-
-The maintained workflow uses one ordered-pipeline example instead of a manual
-two-run NPC-to-spell or NPC-to-combat handoff. Existing module keys, artifact
-contracts, reference slot names, prompt IDs, and D&D evidence policy remain
-unchanged.
-
-## Included Work
-
-- Configuration parsing, validation, cloning, defaults, redaction, and
-  documentation for explicit steps and structured generated references.
-- Domain-neutral resolved step, dependency, producer, and consumer identities.
-- Generated-artifact compatibility metadata on reference-slot contracts,
-  including D&D NPC-list declarations for every `npcs` consumer.
-- Step-aware preparation metadata and runner orchestration.
-- Canonical codec handoff into existing reference request contracts.
-- Required-dependency failure and bounded provenance behavior.
-- Dependency-aware checkpoint reuse, invalidation, events, and selective step
-  recomputation.
-- D&D NPC-first production composition for spell and combat-turn consumers.
-- Refactoring the affected D&D consumers so generated NPC references are
-  available at operation time while retaining early static construction.
-- Maintained examples and current architecture, configuration, CLI, operations,
-  internal, integration, and testing documentation.
-- An ADR recording the bounded ordered-step extension to the fixed pipeline
-  architecture and its explicit rejection of a general DAG.
-
-## Explicitly Out Of Scope
-
-- D&D item extraction or any other new artifact lane.
-- Cross-artifact NPC ID fields or artifact-schema migration machinery.
-- Arbitrary DAGs, conditional branches, loops, joins, dynamic step creation, or
-  module-controlled scheduling.
-- Multiple source inputs, per-step input adapters, per-step chunk plans, or
-  per-step output encoders.
-- Aggregating multiple generated artifacts into one reference slot.
-- Optional or best-effort generated dependencies; a configured dependency is
-  required in this scope.
-- Prior-run or cross-pipeline generated references.
-- `--only` dependency closure for explicit multi-step pipelines.
-- Cross-lane reconciliation or domain concepts in the generic framework.
-- Live-provider tests or model-quality changes to D&D prompts.
-
-## Acceptance Criteria
-
-The scope is complete when:
-
-- all existing single-step configurations retain their current behavior;
-- explicit step order and dependency topology resolve deterministically and
-  affect pipeline identity;
-- invalid producer, consumer, conflict, ordering, type, schema, media, and
-  cardinality configurations fail before source processing when statically
-  discoverable, while content-size violations fail at handoff;
-- no consumer step begins before all required generated artifacts are accepted,
-  canonicalized, and validated for its target slots;
-- one producer artifact fans out safely to every compatible target selected by
-  a step-scoped binding;
-- missing required producer output fails the complete run before dependent work;
-- changing NPC output invalidates spell and combat-turn checkpoints while
-  leaving compatible independent work reusable;
-- selective step recomputation executes exactly the selected dependency closure
-  and reports why work was executed, reused, or invalidated;
-- the D&D ordered workflow supplies NPC content to spell extraction, combat-turn
-  extraction, and combat-turn normalization without treating it as evidence;
-- completion timing cannot change public ordering, failure selection, or
-  dependency behavior;
-- output, manifests, checkpoints, and debug artifacts contain the required
-  identities and provenance without leaking generated reference content; and
-- repository-wide tests, vet, build, maintained-example checks, and
-  documentation validation pass.
-
-## Testing Strategy
-
-Tests should protect behavior and invariants rather than the implementation's
-internal scheduler shape.
-
-- Configuration contract tests own legacy shorthand, explicit step parsing,
-  source-form discrimination, conflicts, and redaction.
-- Resolution tests own ordering, global lane uniqueness, dependency validation,
-  slot compatibility, fan-out, cloning, canonical JSON, and digest changes.
-- Runner tests own step barriers, within-step bounded concurrency, stable
-  ordering, cancellation, required-producer failure, and immutable handoff.
-- Checkpoint tests own producer decoding, exact dependency matching, transitive
-  invalidation, forced recomputation, cold misses, and bounded decisions.
-- One CLI contract test should cover the recompute control and its invalid
-  combinations.
-- One D&D integration test with offline fake LLM responses should prove the
-  complete NPC-to-spell-and-combat handoff, including combat normalization.
-- Maintained configuration examples should be parsed and resolved through the
-  production catalog.
-
-Do not add scheduler choreography tests, exact goroutine-count assertions,
-complete manifest snapshots, exact diagnostic strings, or duplicated tests for
-every invalid configuration at every layer. No test may require credentials or
-a live model provider.
-
-## Open Questions
-
-None required to define this scope. Exact internal type names and implementation
-decomposition are intentionally not feature-policy decisions.

+# PromptKit v0.5 Integration And LLM Profile Policy
+
+## Purpose
+
+This roadmap defines the target state for upgrading Notarius from PromptKit
+v0.3.0 to v0.5.0 and adopting the upstream runtime and profile facilities that
+directly improve Notarius. It also defines the application policy for stable,
+domain-oriented LLM profile names, operator overrides, pipeline inheritance,
+profile validation, provider defaults, checkpoint identity, and documentation.
+
+The ordered work needed to reach this state belongs in
+[the implementation plan](implementation.md). Current behavior remains defined
+by the canonical documentation outside `docs/roadmap/` until the corresponding
+work is implemented.
+
+## Background
+
+Notarius currently pins PromptKit v0.3.0. Its adapter prepares a request once
+for debug material and then independently runs the original request, causing
+PromptKit to prepare the same logical call a second time. The CLI validates an
+explicit profile by preparing a synthetic prompt. PromptKit profile selection
+can be repeated on individual module bindings or replaced for one invocation
+with `--llm-profile`, but a configured pipeline cannot yet declare one inherited
+profile policy.
+
+PromptKit v0.4.0 and v0.5.0 add the upstream boundaries needed to improve these
+areas:
+
+- [v0.4.0](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0/docs/releases/v0.4.0.md)
+  adds opaque prepared executions, exact profile and prompt inspection, and a
+  typed backend-capacity error;
+- [v0.5.0](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0/docs/releases/v0.5.0.md)
+  adds application fallback profile filesystems and stops sending unset
+  optional sampling controls as framework-selected provider values; and
+- the [v0.5.0 format contract](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.5.0/docs/formats.md)
+  defines the resulting profile-source and execution-setting precedence.
+
+A source-compatibility test of the current Notarius repository against
+PromptKit v0.5.0 completed successfully. The work is therefore primarily an
+intentional runtime and configuration migration rather than a repair for a
+breaking Go API change.
+
+## Goals
+
+- Pin and document PromptKit v0.5.0 as Notarius's supported upstream contract.
+- Execute the exact prepared request snapshot whose safe details are recorded
+  in Notarius debug material.
+- Validate configured PromptKit profiles through the upstream inspection API
+  without synthetic prompts, provider calls, or credential-value access.
+- Give Notarius an application-owned, operator-overridable
+  `dnd-extraction` profile fallback.
+- Let a pipeline choose one default LLM profile without repeating that ID on
+  every LLM-backed binding.
+- Apply profile inheritance and run-wide overrides only where the resolved
+  module or validator can use an LLM.
+- Preserve accurate checkpoint invalidation, effective profile provenance,
+  redaction, cancellation, concurrency, and provider-neutral module contracts.
+- Provide operators with one clear deployment pattern for production,
+  development, and local profile definitions.
+
+## Target End State
+
+### PromptKit Runtime Boundary
+
+Notarius depends on PromptKit v0.5.0 and uses its public APIs rather than
+reimplementing source or execution resolution.
+
+For each structured completion, the adapter:
+
+1. builds one PromptKit run request from the provider-neutral Notarius request;
+2. calls `PrepareExecution` once;
+3. immediately arranges an idempotent `Discard` for every unexecuted handle;
+4. obtains credential-redacted `Details` for debug and response metadata; and
+5. calls `RunPrepared` so generation uses that exact frozen snapshot.
+
+The debug prompt and successful result therefore describe the same selected
+profile, rendered messages, input bytes, session, output contract, and effective
+settings even when a filesystem-backed source changes concurrently. PromptKit
+handle types remain private to `internal/framework/llm`.
+
+PromptKit admission failures continue to match Notarius's provider-neutral
+`ErrLLMCapacityExceeded` contract. When PromptKit supplies a `CapacityError`,
+the adapter obtains the normalized backend ID through `errors.As` and may add it
+to safe application-owned diagnostics without parsing upstream error wording.
+The backend ID does not become a provider-specific module contract.
+
+### Optional Provider Controls
+
+Notarius accepts PromptKit v0.5.0's new behavior for `temperature`,
+`max_tokens`, and `top_p`: an unset setting is omitted from compatible provider
+requests and the provider chooses its own default. Notarius does not restore
+PromptKit's former implicit `top_p: 1` value globally.
+
+An operator who requires a particular value specifies it in the selected
+PromptKit profile. The application fallback described below intentionally
+leaves these controls unset. A human-reviewed D&D extraction comparison should
+be performed after the upgrade, but paid or nondeterministic model output is
+not part of the default automated test suite.
+
+### Profile Inspection
+
+Pipeline-aware configuration validation uses `Engine.InspectProfile` for every
+effective explicit profile ID. It verifies that the profile exists, parses and
+validates, resolves its backend and target, and is compatible with the engine's
+registered backends. It does not create a synthetic prompt, load prompt inputs,
+contact a provider, or require credential values to exist in the validation
+process environment.
+
+Credential availability is execution-time state. PromptKit preparation still
+enforces the selected profile's credential contract before generation. This
+keeps `notarius config validate` useful in build and deployment validation
+environments where secrets are deliberately absent.
+
+PromptKit construction for inspection and execution uses one shared internal
+profile-source and backend-option path. The CLI does not expose PromptKit public
+types across the Notarius LLM boundary merely to perform inspection.
+
+`InspectPrompt` is not adopted merely because it exists. It remains available
+for a later, separately defined module-to-prompt interface preflight if a
+concrete validation requirement justifies that additional contract.
+
+### Application And Operator Profile Sources
+
+Notarius embeds one ordinary PromptKit YAML profile with the stable ID
+`dnd-extraction`. It is an application fallback registered through
+`WithFallbackProfileFS`, is owned by the D&D module family, and initially
+preserves the current effective D&D baseline:
+
+- backend: PromptKit's built-in `openrouter` backend;
+- model: `openai/gpt-5.6-luna`;
+- reasoning effort: unset, allowing OpenAI's backend to apply its default of
+  `medium`;
+- generation timeout: 240 seconds;
+- service tier: `flex`; and
+- no application-selected `temperature`, `max_tokens`, or `top_p`.
+
+All maintained D&D LLM prompt definitions use `dnd-extraction` as their
+`default_profile`. The ID communicates workload intent rather than a provider,
+model, or environment. Changing the embedded fallback is an intentional
+Notarius execution-policy change and participates in checkpoint identity.
+
+Effective profile definitions resolve in PromptKit's order:
+
+1. programmatic in-memory profiles used by tests or explicit consumers;
+2. the operator source configured by `promptkit.profile_file` or
+   `promptkit.profile_dir`;
+3. the Notarius application fallback source; and
+4. PromptKit's embedded built-in catalog.
+
+Only an absent ID falls through to the next source. A matching profile is a
+complete definition: fields are not merged with a lower-precedence definition,
+and a malformed matching operator profile fails rather than silently selecting
+the application fallback.
+
+Production, development, and local deployments should normally provide
+different complete definitions for the same `dnd-extraction` ID. An operator
+source is optional because the application fallback keeps the maintained D&D
+workflow usable, but a deployment that needs an intentional model or backend
+policy should configure its own definition.
+
+### Domain Ownership And Asset Assembly
+
+The D&D fallback profile remains under `internal/modules/dnd` and is registered
+by the D&D registrar, consistent with ADR-0004. Generic LLM plumbing knows how
+to collect and flatten application fallback profile filesystems but contains no
+D&D model or policy knowledge.
+
+The shared asset registry detects invalid roots, unreadable sources, and
+duplicate flattened paths. PromptKit remains responsible for strict profile
+YAML parsing, duplicate profile-ID detection, source precedence, and effective
+target resolution. The same assembled fallback source is supplied to runtime
+execution and CLI profile inspection.
+
+### Explicit Module Execution Metadata
+
+Every registered input, chunk, extract, merge, normalize, and output module
+declares one required execution class: `deterministic` or `llm_backed`.
+Validator registrations continue to declare the same distinction through their
+validator specifications.
+
+The registered specification is authoritative for configuration resolution.
+Current production classifications are:
+
+- the D&D scene chunker, all D&D extractors, and the D&D NPC normalizer are
+  LLM-backed;
+- the Seriatim input adapter, generic chunker, all current mergers, all other
+  current normalizers, and the JSON output encoder are deterministic; and
+- current validators retain their declared classifications.
+
+Missing or unsupported execution metadata is a registration error. Explicitly
+assigning `llm_profile` to a deterministic module or validator is a pipeline
+resolution error. The framework does not infer execution class by inspecting
+domain package names or concrete implementation types at runtime.
+
+The module specification replaces the chunk runner's special runtime
+execution-class probe. Effective resolved bindings already express the result:
+only LLM-backed bindings may retain a non-empty profile.
+
+### Pipeline-Level Profile Default
+
+Configuration version 4 gains one optional non-empty pipeline field:
+
+```yaml
+pipelines:
+  dnd-session:
+    llm_profile: dnd-extraction
+```
+
+No configuration-version increment is required because the field is additive
+and existing files remain valid. An explicitly present blank value is invalid.
+
+For every selected LLM-backed module and validator, the effective profile uses
+this precedence:
+
+1. non-empty run-wide `--llm-profile` override;
+2. binding-specific `llm_profile`;
+3. pipeline-level `llm_profile`; and
+4. the prompt definition's `default_profile`, represented by an empty effective
+   Notarius binding profile.
+
+The run-wide override and inherited pipeline default never attach to a
+deterministic binding. Binding-specific exceptions remain available when one
+operation needs a different cost, latency, quality, backend, or reasoning
+policy.
+
+Inheritance is resolved after module and validator selection, including
+`--only` lane filtering, but before effective-pipeline validation, digest
+construction, explicit-profile inspection, checkpoint construction,
+preparation, execution, or provenance capture. Only profiles used by selected
+LLM-backed bindings are inspected. An unused pipeline default in a pipeline
+with no selected LLM-backed work does not require an otherwise unused profile
+to exist.
+
+The resolved pipeline contains effective binding profiles rather than a second
+runtime inheritance mechanism. Two pipelines that differ only by spelling the
+same effective policy once as a pipeline default and once on every LLM-backed
+binding have the same semantic resolved digest. Changing an effective profile
+changes the digest and applicable checkpoint identity.
+
+### Provenance And Checkpoints
+
+The PromptKit profile-source checkpoint fingerprint covers:
+
+- the PromptKit v0.5.0 built-in profile catalog identity;
+- exact application fallback profile asset content; and
+- exact configured operator profile YAML content, when present.
+
+The existing local-backend target fingerprint remains separate and continues
+to exclude scheduling-only concurrency limits. Fingerprints contain hashes and
+stable markers, not profile contents, filesystem paths, endpoints, credentials,
+or other secrets.
+
+Changing the PromptKit version, application fallback, operator profile, or
+effective pipeline profile makes incompatible LLM checkpoints ineligible for
+reuse. The dependency upgrade is expected to invalidate checkpoints produced
+under v0.3.0.
+
+Successful run manifests continue to record only profiles actually selected by
+PromptKit, including their effective model, backend, and reasoning metadata.
+Debug output reports the same effective execution snapshot used for generation.
+
+### Operator Documentation And Examples
+
+Canonical documentation clearly distinguishes:
+
+- Notarius prompt and schema assets embedded in the application;
+- Notarius application fallback profiles embedded in the application;
+- PromptKit's own embedded built-in profiles; and
+- operator profile files on the deployment filesystem.
+
+The configuration reference owns the pipeline field, profile-source fields,
+validation rules, and precedence. Operations owns deployment layout, working
+directory behavior, credentials, and environment-specific profile management.
+The PromptKit integration document owns the pinned upstream contract and
+source-precedence boundary. Internal documents describe asset registration,
+resolution, inspection, prepared execution, fingerprinting, and tests without
+duplicating user-facing field definitions.
+
+The maintained examples continue to include only the minimal and complete D&D
+configurations. They use the stable `dnd-extraction` policy, and one maintained
+PromptKit profile file under `examples/` demonstrates an operator override.
+Examples remain secret-free and are validated without live provider calls.
+
+## Out Of Scope
+
+- Implementing the separate deterministic prompt-session identity roadmap
+  item.
+- Changing the default `concurrency.total_llm` value; PromptKit's retained
+  OpenRouter capacity of 16 remains relevant to that separate item.
+- Adding model evaluation as a deterministic or CI correctness gate.
+- Automatically selecting production, development, or local environments.
+  Deployment configuration chooses the operator profile source.
+- Profile inheritance, partial profile merging, or cross-profile aliases.
+- Exposing PromptKit types to modules, validators, durable output contracts, or
+  public configuration structures.
+- Adopting `InspectPrompt` without a separately justified prompt-interface
+  validation contract.
+
+## Acceptance Criteria
+
+- Notarius builds and its offline test suite passes with PromptKit v0.5.0.
+- Every structured completion executes the exact snapshot used for safe debug
+  prompt details.
+- Profile preflight uses profile inspection and no synthetic prompt.
+- The embedded `dnd-extraction` fallback resolves without an operator source,
+  and a matching valid operator profile replaces it completely.
+- Every production module has explicit, correct execution metadata.
+- Pipeline, binding, CLI, and prompt-default precedence behaves as defined for
+  modules and validators, while deterministic bindings remain profile-free.
+- Effective profiles participate in pipeline digests, profile inspection,
+  checkpoint identity, debug records, and run provenance at the appropriate
+  boundaries.
+- The dependency and application fallback changes invalidate incompatible old
+  checkpoints without exposing profile or credential content.
+- Canonical documentation and maintained examples accurately describe and
+  exercise the implemented operator workflow.
+- Default tests remain deterministic, offline, credential-free, and focused on
+  Notarius-owned behavior rather than duplicating PromptKit's upstream suite.
