+# ADR-0013: Use request-local candidate handles for semantic reconciliation
+
+**Status:** Accepted
+**Date:** 2026-08-09
+
+## Context
+
+Several typed normalize stage modules need semantic reconciliation after
+deterministic preprocessing: a model can judge whether source-backed candidates
+refer to the same underlying entity, while application code remains responsible
+for constructing the normalized artifact. Requiring the model to reproduce a
+candidate's full contextual selector makes the response larger and introduces
+avoidable formatting, ordering, and transcription failure modes.
+
+Reconciliation must preserve the exact typed artifact boundary established by
+[ADR-0003](0003-typed-interfaces-with-two-zone-data-model.md), the domain-neutral
+framework and concrete-domain dependency direction established by
+[ADR-0004](0004-package-modules-by-domain.md), and the distinction in
+[ADR-0009](0009-minimal-evidence-grounded-extraction-artifacts.md) between source
+evidence and auxiliary identity context. It also needs a concrete, narrowly
+scoped application of the request-local-label exception allowed by
+[ADR-0012](0012-resolve-opaque-entity-identifiers-deterministically.md).
+
+## Decision
+
+Semantic reconciliation will be a domain-neutral framework mechanism used by
+typed normalize stage modules. A consuming artifact family will retain
+ownership of its typed records, identity rules, consolidation policy, durable
+IDs, and domain warnings; the framework mechanism will not infer those rules
+from arbitrary data.
+
+For each reconciliation request, deterministic code will assign every eligible
+model-visible candidate a contiguous, one-based integer handle. The model may
+receive the candidate's contextual label, source references, and bounded source
+context needed to judge identity, but its structured response will identify
+candidates only by those supplied handles. A handle is local to one request,
+does not represent entity identity, and must never enter a durable artifact or
+be used to derive a durable ID.
+
+The model will propose duplicate groups and select one supplied member of each
+group as canonical. Deterministic code will resolve the handles through the
+retained request mapping, validate the complete proposal, discard unsafe
+groups, and apply only validated groups through typed domain-owned policy. The
+model will not synthesize replacement records or directly mutate an artifact.
+
+Every reconciliation prompt will combine a mandatory framework-owned protocol
+and safety policy with an explicitly selected semantic policy. The semantic
+policy may be the conservative generic policy or a domain-owned policy, but it
+cannot replace the shared response protocol or deterministic safety boundary.
+
+## Alternatives considered
+
+- Return durable application IDs. Opaque IDs do not help semantic judgment,
+  expose application identity mechanics, and make model output reproduce data
+  that deterministic code already owns.
+- Return names alone or copied contextual selectors. Names can be ambiguous,
+  while reproducing labels and source ranges adds response complexity and
+  creates mismatches without adding semantic information. Request-local
+  handles preserve exact selection without either failure mode.
+- Ask the model to return synthesized canonical replacement records. This
+  would transfer typed artifact construction, provenance consolidation, and
+  durable identity policy to a probabilistic boundary.
+- Reconcile reflection-discovered fields or arbitrary JSON. This would weaken
+  the typed artifact contract and move domain semantics into generic code.
+- Hide reconciliation inside extraction or another stage. This would obscure
+  stage ownership and create cross-stage behavior outside the fixed pipeline;
+  reconciliation remains explicit normalize-stage behavior.
+- Let each domain replace the complete prompt protocol. This would duplicate
+  safety mechanics and allow domain policy to bypass the common response and
+  validation contract.
+
+## Consequences
+
+Model responses become smaller and easier to validate, while deterministic
+application code retains authority over identity, provenance, ordering, and
+typed artifact construction. The framework requires a request-local mapping,
+bounded context preparation, a private integer response contract, proposal
+assessment, and shared prompt assets. Each consuming artifact family still
+requires a typed adapter for its irreducibly domain-specific rules.
+
+Request-local handles are deliberately unsuitable for persistence, logging as
+entity identity, checkpoint contracts, or cross-request correlation. Changes
+to shared protocol and policy assets must participate in the normal prompt,
+schema, and checkpoint fingerprint mechanisms.
+
+The shared mechanism and its initial D&D registry consumers are now
+implemented. Current behavior is documented in
+[Module Internals](../internal/modules.md#semantic-reconciliation) and
+[D&D Module Internals](../internal/dnd.md#semantic-registry-reconciliation).

+# ADR-0014: Use feedback-aware validation retries
+
+**Status:** Accepted
+**Date:** 2026-08-26
+
+## Context
+
+Validation can identify a candidate defect after a producer has returned an
+otherwise well-formed result. Retrying without the validator's deterministic,
+bounded feedback wastes the useful diagnosis, while treating validator
+execution failures as defects would ask a producer to repair conditions it
+cannot control. The mechanism must preserve typed producer ownership,
+checkpoint safety, and the repository's sensitive-data boundaries.
+
+## Decision
+
+The implementation will keep three independent budgets: the producer binding's
+outer `retries` budget, PromptKit's structured-output repair budget, and each
+validator's execution-retry budget. Validators will run sequentially in their
+configured order and aggregate both rejections and execution failures before a
+candidate disposition is selected.
+
+A correction-capable producer will provide the exact single LLM response that
+controlled its candidate using the `single_response_v1` protocol. A correction
+attempt will reconstruct the ordinary request and append exactly two fresh
+messages: that latest response as `assistant`, followed by one deterministic
+aggregate correction request as `user`. Earlier turns will not accumulate.
+
+Validator failures will not recurse into correction. Pipeline policy owns
+terminal disposition, with field-by-field producer overrides over pipeline
+defaults: structural failure and semantic rejection default to `fail_run`, and
+validator execution failure defaults to `warn_continue`. Validators can report
+facts and bounded corrective guidance, but never decide disposition.
+
+Rejected and structurally invalid candidates will not advance. A candidate
+allowed through after a validator execution failure will retain explicit
+incomplete-validation provenance and will not be checkpointed. Exact response
+and correction text remain attempt-local: they are excluded from ordinary
+errors, warnings, manifests, receipts, caches, checkpoints, and default debug
+summaries.
+
+## Alternatives considered
+
+- Retry every producer after any validation outcome. This conflates producer
+  defects with validator operational failures and wastes retry budget.
+- Let validators decide whether to continue. This would distribute pipeline
+  disposition policy across validators and undermine consistent defaults.
+- Reuse the full prior conversation. Accumulated turns introduce unbounded
+  prompt growth and make correction behavior depend on incidental history.
+- Persist raw responses to simplify diagnosis. Raw model output and correction
+  guidance may be sensitive and do not belong in durable pipeline records.
+
+## Consequences

+# Consuming The Complete D&D Pipeline
+
+Use this workflow when an orchestrator runs the maintained complete D&D
+pipeline and consumes its structured JSON artifacts. The generic
+[subprocess consumer guide](subprocess.md) owns process-level responsibilities;
+this guide connects that workflow to the complete D&D configuration, its
+Seriatim input, and its artifact inventory.
+
+The [CLI reference](../cli.md), [configuration reference](../config.md),
+[run-result receipt](../integrations/run-result.md), and
+[published JSON output contract](../integrations/json-output.md) remain the
+canonical definitions of those public interfaces.
+
+## Prepare And Validate The Deployment
+
+Start from the maintained
+[complete D&D configuration](../../examples/dnd-complete.config.yml). It uses
+the `dnd-session` pipeline and demonstrates every implemented D&D lane, ordered
+artifact handoffs, campaign references, chunk-map publication, and evidence
+context.
+
+A deployment must provide its own PromptKit profile and campaign reference
+files. Use absolute paths for service and subprocess deployments. In
+particular, observe these different resolution rules:
+
+- reference paths in YAML are resolved relative to the Notarius configuration
+  file; and
+- `promptkit.profile_file` is resolved relative to the Notarius process working
+  directory.
+
+Do not copy the repository example's relative profile path into a deployment
+without also controlling that working directory. The complete path and profile
+rules are defined in [Configuration](../config.md).
+
+Preflight the deployed configuration before processing sessions and whenever
+it changes:
+
+```sh
+notarius config validate \
+  --config /absolute/path/to/notarius.yml \
+  --pipeline dnd-session
+```
+
+Provide credentials through the environment or the documented configuration
+mechanism. Do not put credentials in command arguments, generated
+configuration, or logs.
+
+## Supply The Transcript
+
+The complete pipeline consumes a Seriatim JSON document. The
+[Seriatim input contract](../integrations/seriatim.md) defines its required
+metadata, segments, and validation rules. Preserve segment IDs: D&D artifact
+citations use those segment IDs as source-unit ranges.
+
+When the caller maintains several transcript tiers, use the final trimmed JSON
+transcript so extraction operates on the same session content presented to
+later consumers. For example, Narratio identifies this implemented artifact as
+`narratio.transcript.final_trimmed` and normally stores it at
+`transcripts/final.trimmed.json`.
+
+Notarius generates a stable prompt session from the resolved input module and
+the exact input bytes. An ordinary orchestrator should not pass `--session-id`.
+Use that override only when intentionally changing the routing relationship
+between invocations; it is not a credential or output identity.
+
+## Run Notarius
+
+Invoke the pipeline with explicit absolute paths and request its
+machine-readable receipt:
+
+```sh
+notarius run dnd-session \
+  --config /absolute/path/to/notarius.yml \
+  --input /absolute/path/to/transcripts/final.trimmed.json \
+  --output-dir /absolute/path/to/notarius-output \
+  --json
+```
+
+The caller should:
+
+- capture stdout and stderr separately;
+- propagate cancellation and impose an operator-appropriate timeout;
+- wait for process completion before interpreting stdout; and
+- retain stderr for diagnosis without copying secrets or transcript content
+  into other logs.
+
+Only exit status 0 permits decoding stdout as a receipt. Ignore stdout after a
+nonzero exit because a failed receipt write can leave partial bytes. The
+[CLI reference](../cli.md#output-streams-and-exit-statuses) defines the complete
+stream and exit-status contract.
+
+## Discover The Published Bundle
+
+Decode the successful stdout document as a supported run-result schema. For
+the current contract, `schema_version` is `notarius.run-result.v1`. Tolerate
+unknown fields allowed by that version, but reject an unsupported schema
+version.
+
+Use the receipt's absolute `output_directory` as the exact run-specific bundle
+root. Do not scan the output root for its newest directory, guess a run ID, or
+construct a bundle path. Resolve `index_file` beneath `output_directory` and
+reject an absolute logical path or any result that escapes the bundle root.
+
+The complete configuration uses the application validation defaults. A caller
+that requires fully validated D&D artifacts must also require receipt
+`validation_status: approved`; a successful `incomplete` result reflects the
+configured validator-failure continuation policy and carries its bounded
+validator provenance in `validation_summaries`.
+
+Read `index.json` and locate each requested lane in `output_files` by its exact
+`lane_id`. Do not guess a lane filename. Before decoding a payload:
+
+1. resolve its descriptor's relative `file` beneath the bundle root with the
+   same confinement check;
+2. verify the descriptor's media type and schema identity against the linked
+   artifact contract; and
+3. decode the payload according to that contract.
+
+The [published JSON output contract](../integrations/json-output.md) defines
+the index and bundle layout. Treat all paths obtained from a decoded external
+document as untrusted until confined to their documented root.
+
+## Complete Artifact Inventory
+
+When every configured lane is accepted, the complete example publishes these
+lane artifacts:
+
+| Lane ID | Purpose | Canonical contract |
+| --- | --- | --- |
+| `item-registry` | Canonical registry of encountered items and currency. | [Item registry](../integrations/dnd-item-registry-artifacts.md) |
+| `npc-registry` | Canonical registry of named NPCs. | [NPC registry](../integrations/dnd-npc-registry-artifacts.md) |
+| `location-registry` | Canonical registry of named locations. | [Location registry](../integrations/dnd-location-registry-artifacts.md) |
+| `scene-descriptions` | Classification, title, and summary for each scene. | [Scene descriptions](../integrations/dnd-scene-description-artifacts.md) |
+| `item-occurrences` | Source-grounded item discovery, acquisition, use, transfer, and loss events. | [Item occurrences](../integrations/dnd-item-occurrence-artifacts.md) |
+| `spells` | Source-grounded spell casts and casters. | [Spell casts](../integrations/dnd-spell-artifacts.md) |
+| `combat-turns` | Source-grounded combat turn participation. | [Combat turns](../integrations/dnd-combat-turn-artifacts.md) |
+| `npc-occurrences` | Source-grounded NPC interaction occurrences. | [NPC occurrences](../integrations/dnd-npc-occurrence-artifacts.md) |
+| `location-occurrences` | Source-grounded location occurrences. | [Location occurrences](../integrations/dnd-location-occurrence-artifacts.md) |
+| `enemy-events` | Source-grounded enemy combat events. | [Enemy events](../integrations/dnd-enemy-event-artifacts.md) |
+
+The JSON encoder always publishes these bundle-management files:
+
+| File | Purpose |
+| --- | --- |
+| `index.json` | Discovery document for lane and pipeline-wide artifacts. |
+| `manifest.json` | Run provenance and result summaries. |
+| `rejected.json` | Rejected pipeline outputs. |
+| `warnings.json` | Accepted-output and run warnings. |
+
+The complete configuration also requests two pipeline-wide artifacts:
+
+- [`chunk-map.json`](../integrations/chunk-map.md), the accepted chunk plan and
+  chunk metadata; and
+- [`evidence-context.json`](../integrations/evidence-context.md), a reading
+  excerpt containing the union of selected cited source units and the
+  configured surrounding window.
+
+Discover both from their top-level `index.json` descriptors rather than
+treating them as lanes. Evidence context is convenient reading material, not
+authoritative provenance; citations in the normalized lane payloads remain the
+evidence contract.
+
+Every optional or lane file is published only when its corresponding artifact
+is available. A successful process does not guarantee that all configured
+lanes were accepted.
+
+## Decide What Counts As Consumer Success
+
+Exit status 0 means Notarius completed the pipeline and published its result
+bundle. The receipt or bundle may still report warnings, rejected outputs, or
+missing lane descriptors. A downstream consumer must define its own required
+artifact set explicitly.
+
+A caller that claims to consume the complete D&D workflow should normally
+require all ten lane IDs in the table and verify each descriptor's expected
+contract. If any required lane is missing, rejected, or incompatible, fail the
+caller's extraction step while retaining the Notarius bundle for diagnosis. A
+consumer that needs only a subset may define and document a narrower policy.
+
+Keep the successful receipt with the complete published bundle. Retain
+`manifest.json`, `rejected.json`, `warnings.json`, and captured process logs as
+required by the caller's provenance, diagnosis, and retention policies. Avoid
+selectively copying payload files without also preserving enough index and
+manifest information to identify their originating run and contracts.
+
+The transcript, lane artifacts, evidence context, manifest, debug data, and
+logs can all contain private campaign information. Apply the same access,
+publication, and retention controls used for the source transcript.
+
+## Consumer Checklist
+
+- Validate the deployed Notarius configuration and `dnd-session` pipeline.
+- Pass the final trimmed Seriatim JSON transcript with stable segment IDs.
+- Use absolute configuration, input, output-root, profile, and reference paths
+  in service deployments.
+- Capture stdout and stderr separately and enforce cancellation and timeout.
+- Parse stdout only after exit status 0.
+- Accept only supported receipt, index, and artifact schema versions while
+  tolerating permitted unknown fields.
+- Use the receipt's `output_directory`; never guess the run directory.
+- Confine `index_file` and every descriptor path to the published bundle root.
+- Discover lanes by `lane_id` and verify descriptor compatibility before
+  decoding payloads.
+- Enforce an explicit required-lane policy and inspect rejections and warnings.
+- Preserve the receipt and sufficient bundle provenance for every retained
+  artifact.
+- Protect all transcript-derived files and diagnostic streams as sensitive
+  campaign data.

+The framework obtains direct source references only through typed evidence
+projections of accepted normalized artifacts in the configured lane allowlist.
+It validates each reference against the current source document, expands its
+range by `window_units` source-unit positions on each side, clamps at document
+boundaries, and takes the union of all expanded ranges. The output contains
+each selected source unit once in source-document position order, regardless
+of numeric unit IDs. Repeated references, overlapping windows, and citations
+from multiple lanes do not duplicate a unit. Rejected, failed, absent,
+inactive, and unselected lanes contribute nothing.

+## Semantic Reconciliation
+
+`internal/framework/semanticreconcile` is a domain-neutral strategy used by a
+typed normalize module; it is not itself a selectable stage module. A
+source-backed artifact-family normalizer projects its deterministic records
+into contextual candidates and owned typed record envelopes, supplies its
+chosen prompt identity and resolved LLM profile, and constructs an engine with
+explicit limits. The core filters invalid evidence, assigns contiguous
+request-local integer handles, renders bounded candidate and transcript
+materials, invokes the structured-completion boundary, and assesses the
+returned duplicate groups into a stable non-overlapping plan.
+
+The normalizer then applies that plan through a typed `ApplicationPolicy`. The
+core preserves ungrouped records, contribution order, and provenance while the
+artifact family owns group guards, field and evidence consolidation, durable
+ID derivation, retry and fallback presentation, warnings, and postconditions.
+Request-local handles do not enter the typed value or durable artifact. Fewer
+than two eligible candidates skips model invocation; exceeding a candidate or
+combined-material bound preserves the deterministic result under the family's
+fallback policy. Provider, transport, cancellation, and context-construction
+failures remain execution errors.
+
+When the engine actually makes a proposal call, its typed result carries the
+owned exact proposal response under the same correction contract as other
+eligible producers. Deterministic skip, limit, and fallback outcomes carry no
+model candidate, so a later rejection applies terminal policy without spending
+an ineffective semantic retry.
+
+The core supplies a conservative generic prompt and the single private
+response schema. A domain prompt may substitute its semantic instructions but
+mounts the core-owned protocol and candidate/transcript presentation assets.
+Prompt, schema, policy, and limit identities participate in manifest metadata
+and checkpoint fingerprints. The generic registrar owns production
+registration of those shared assets; a consuming domain registrar owns only
+its domain prompt.

+# Source Releases
+
+This procedure is for maintainers publishing Notarius source releases. A
+release is an immutable lightweight `vMAJOR.MINOR.PATCH` tag on `main` together
+with its checked-in `docs/releases/<tag>.md` note. Tag CI validates that source
+candidate after publication; it does not publish or repair a release.
+
+Notarius publishes no binaries, archives, checksums, signatures, containers,
+package-manager entries, or Gitea release objects. Windows is not supported.
+Do not create retrospective notes for the pre-procedure `v0.1.0`, `v0.2.0`, or
+`v0.3.0` tags.
+
+## Select And Describe The Release
+
+Choose an unused stable semantic version in the form `vMAJOR.MINOR.PATCH`.
+Prereleases are not supported. Before `v1.0.0`, a minor release may change a
+documented CLI, configuration, durable artifact, integration, or operating
+contract when its note explains the impact and required operator action. A
+patch release must not intentionally break those documented contracts within
+its minor line.
+
+Create the version-matched note as part of the candidate. Every new note uses
+this structure, with concise, truthful content in each section:
+
+```markdown
+# Notarius vMAJOR.MINOR.PATCH
+
+This release ...
+
+## Summary
+
+## Compatibility
+
+## Upgrade
+
+## Changes
+```
+
+The note is a historical summary. Link to current canonical documentation for
+exact behavior, and update that documentation in the candidate rather than
+using the note as a substitute.
+
+## Prepare The Candidate
+
+Set the selected release version and disable Go workspace use for every
+candidate command:
+
+```sh
+RELEASE_VERSION=vMAJOR.MINOR.PATCH
+export RELEASE_VERSION GOWORK=off
+```
+
+Run the shared source-candidate checks from the repository. They cover module
+hygiene, tests, race tests, vet, builds, formatting, whitespace, maintained
+configuration validation, and the Linux and Darwin command-build matrix:
+
+```sh
+./scripts/check-release-source.sh "$RELEASE_VERSION"
+```
+
+Before committing, manually follow every changed local Markdown link and
+review the candidate for unintended files, generated output, credentials, or
+other unrelated changes. Commit the release note and all affected current
+documentation, then run the shared checker against that exact candidate. Push
+the candidate commit to `main` only after it succeeds. Record the exact commit
+only after that push:
+
+```sh
+RELEASE_COMMIT=$(git rev-parse 'HEAD^{commit}')
+export RELEASE_COMMIT
+```
+
+For private-module installation, configure standard `GOPRIVATE` matching this
+module and ordinary Git authentication for the hosting service before running
+the verification below. The exact authentication mechanism belongs to the
+maintainer environment; never record credentials or environment dumps in a
+release note, command history, or repository file.
+
+## Guard And Publish The Tag
+
+Fetch current remote references, then run this guard without editing the
+candidate. It requires `main`, a clean worktree and index, disabled workspace
+use, a stable release version, the recorded and pushed commit, a matching note,
+and unused local and remote tags:
+
+```sh
+git fetch origin main --tags
+
+if ! printf '%s\n' "$RELEASE_VERSION" |
+  grep -E -x 'v(0|[1-9][0-9]*)\.(0|[1-9][0-9]*)\.(0|[1-9][0-9]*)' >/dev/null
+then
+  printf '%s\n' "invalid release version: $RELEASE_VERSION" >&2
+  exit 1
+fi
+test "$GOWORK" = off
+test "$(git branch --show-current)" = main
+test -z "$(git status --porcelain)"
+test "$RELEASE_COMMIT" = "$(git rev-parse 'HEAD^{commit}')"
+test "$RELEASE_COMMIT" = "$(git rev-parse 'origin/main^{commit}')"
+test -s "docs/releases/$RELEASE_VERSION.md"
+grep -F -x "# Notarius $RELEASE_VERSION" "docs/releases/$RELEASE_VERSION.md"
+for heading in '## Summary' '## Compatibility' '## Upgrade' '## Changes'; do
+  grep -F -x "$heading" "docs/releases/$RELEASE_VERSION.md"
+done
+if git rev-parse -q --verify "refs/tags/$RELEASE_VERSION" >/dev/null; then
+  printf '%s\n' "local tag already exists: $RELEASE_VERSION" >&2
+  exit 1
+fi
+if git ls-remote --exit-code --tags origin "refs/tags/$RELEASE_VERSION" >/dev/null 2>&1; then
+  printf '%s\n' "remote tag already exists: $RELEASE_VERSION" >&2
+  exit 1
+fi
+```
+
+Create an explicitly lightweight tag against the guarded commit, verify its
+target, and push only that tag ref:
+
+```sh
+git -c tag.gpgSign=false tag "$RELEASE_VERSION" "$RELEASE_COMMIT"
+test "$(git cat-file -t "$RELEASE_VERSION")" = commit
+test "$(git rev-parse "$RELEASE_VERSION^{commit}")" = "$RELEASE_COMMIT"
+git push origin "refs/tags/$RELEASE_VERSION:refs/tags/$RELEASE_VERSION"
+```
+
+Never use `git push --tags`, move a published tag, or delete a published tag.
+
+## Verify The Published Release
+
+Confirm that the remote tag still points at the guarded commit and that the
+note is available from the tagged tree:
+
+```sh
+REMOTE_TAG_COMMIT=$(git ls-remote origin "refs/tags/$RELEASE_VERSION" | awk '{print $1}')
+test "$REMOTE_TAG_COMMIT" = "$RELEASE_COMMIT"
+git show "$RELEASE_VERSION:docs/releases/$RELEASE_VERSION.md" >/dev/null
+```
+
+Verify a fresh source installation and its diagnostic version. The temporary
+directory confines the installed command to this check:
+
+```sh
+release_verification_dir=$(mktemp -d)
+trap 'rm -rf "$release_verification_dir"' 0 HUP INT TERM
+mkdir -p "$release_verification_dir/bin"
+GOWORK=off GOBIN="$release_verification_dir/bin" go install \
+  "gitea.maximumdirect.net/eric/notarius/cmd/notarius@$RELEASE_VERSION"
+test "$("$release_verification_dir/bin/notarius" --version)" = "notarius $RELEASE_VERSION"
+```
+
+An exact fresh checkout and `GOWORK=off go build ./cmd/notarius` is an
+equivalent source verification when local installation policy requires it.
+`notarius --version` is diagnostic only; downstream compatibility remains
+defined by the published receipt and artifact contracts.
+
+## Failure And Correction Policy
+
+If candidate validation fails before publication, fix the candidate on `main`,
+rerun the shared checker, and repeat the guards. An unpublished local tag may
+be deleted after inspection.
+
+If the remote tag or tag CI reveals a defect, leave the published tag intact.
+Fix the defect on `main`, choose a new patch version, write a new matching
+note, and repeat this procedure. Do not weaken tag immutability or add release
+assets as a workaround.

+# Notarius v0.4.0
+
+This release strengthens LLM reliability and validation throughout the
+configured pipeline, upgrades the PromptKit integration, and establishes the
+source-release and downstream-consumer workflows needed for broader D&D
+pipeline integration.
+
+## Summary
+
+Notarius now distinguishes PromptKit structural-output repair from
+application-owned semantic validation retries. Producer candidates can run
+through complete deterministic validator chains, receive bounded semantic
+correction guidance, and retry under explicit stage policies. Final run
+receipts and manifests preserve bounded validation provenance, while outputs
+that advance with incomplete validation remain available to the current run
+without entering reusable checkpoint state.
+
+The release also adds a maintained complete D&D subprocess-consumer workflow,
+diagnostic build versions, and the source-only release procedure used to
+publish this version.
+
+## Compatibility
+
+- Configuration files must use schema version 4. Version 3 is not decoded or
+  rewritten; rename the top-level `scriptorium` section to `promptkit` when
+  migrating. See [Configuration](../config.md#migrating-version-3-configuration).
+- PromptKit is pinned to v0.9.0. Operator profile files use PromptKit's v0.9.0
+  format and may use its profile-inheritance support. Notarius continues to
+  resolve operator profiles before embedded fallbacks.
+- Structural-output repair and semantic stage retries are separate bounded
+  mechanisms. Maintained production prompts request one structural repair by
+  default; explicit configuration can override the supported repair count.
+- Validation policy can now fail a run, reject an output, or permit an
+  otherwise valid candidate to advance with incomplete-validation provenance.
+  The application defaults are documented in
+  [Configuration](../config.md#pipelines).
+- The `notarius.run-result.v1` receipt remains at schema version 1 and adds
+  optional validation summaries plus a required validation-status field.
+  Consumers of this pre-release contract should follow the current
+  [run-result receipt](../integrations/run-result.md).
+- Existing D&D artifact schema identities remain unchanged. Validation and
+  producer-policy changes can nevertheless cause previously accepted weak
+  candidates to retry, reject, or fail instead.
+
+## Upgrade
+
+1. Migrate every Notarius configuration to version 4 and rename `scriptorium`
+   to `promptkit`.
+2. Review deployed PromptKit profiles against the pinned v0.9.0 profile format
+   and ensure their credential environment variables are available at run
+   time.
+3. Run `notarius config validate --config <path> --pipeline <id>` before the
+   first production invocation.
+4. Review `structured_output_repair_attempts`, producer retry counts, and
+   `validation_policy` wherever the deployment needs behavior different from
+   the documented defaults.
+5. Update subprocess consumers to inspect receipt `validation_status` and to
+   tolerate the optional bounded `validation_summaries` field. A consumer that
+   requires fully validated artifacts should require `approved`.
+
+## Changes
+
+- Upgraded PromptKit from v0.5.0 through v0.9.0 and adopted profile
+  inheritance, structured-output repair, typed error classification, and the
+  correction-aware completion protocol.
+- Added pipeline and binding configuration for structural repair and terminal
+  validation policy, with strict startup validation and effective-setting
+  provenance.
+- Added feedback-aware retries for chunking, extraction, merge, normalize, and
+  semantic reconciliation producers. Retry prompts contain the exact defective
+  response and actionable semantic correction guidance without exposing
+  internal reason codes or opaque entity identifiers.
+- Added complete validator-chain execution, validator retry handling, bounded
+  warnings, terminal dispositions, and durable validation summaries.
+- Prevented validation-incomplete artifacts and all derived lineage from
+  loading or publishing reusable checkpoints while preserving same-run
+  generated-reference handoff.
+- Tightened cached chunk-plan validation so only completely validated plans are
+  reused or replace stored plans.
+- Added a machine-readable subprocess receipt workflow and complete D&D
+  consumer documentation covering all maintained artifacts.
+- Added source-release checks, immutable lightweight-tag guidance, Linux and
+  Darwin build verification, and diagnostic `notarius --version` output.

+## Near-Term Validation And LLM Reliability
+
+PromptKit now owns structural output repair within one completion. Notarius
+owns stage candidates, validator chains, semantic rejection policy, bounded
+feedback-aware stage retries, validation provenance, and reusable-state
+eligibility. The remaining near-term work applies those completed foundations
+to domain review and operator-facing diagnostics.
+
+### D&D Combat Scene Semantic Validation
+
+- Add an optional production LLM-backed D&D validator that determines whether
+  proposed scene boundaries and classifications represent substantive active
+  combat correctly. Its central quality goal is that active combat is kept in
+  coherent scenes classified as `combat`, rather than split incorrectly or
+  hidden inside scenes classified as `narrative`, `recap`, or `meta`.
+- Resolve the validator's exact target before implementation. The current
+  `dnd/scenes` chunker owns only complete, gap-free source ranges, while the
+  per-chunk `dnd/scene-descriptions` extractor owns the `combat`, `narrative`,
+  `recap`, and `meta` classification. The preferred initial placement is
+  therefore an extract-stage validator for `dnd/scene-descriptions`, where it
+  can compare one proposed kind with the corresponding transcript chunk.
+- Consider a chunk-stage LLM validator only for a distinct boundary-coherence
+  question that can be answered from the complete transcript and proposed
+  range map, such as whether one continuous combat was fragmented across
+  inappropriate scene boundaries. Do not duplicate the same classification
+  judgment at both stages. Moving classification into chunk-plan annotations
+  would change the deliberately minimal, annotation-free chunk contract and
+  requires an explicit architecture review before it is selected.
+- Validate both false negatives and false positives: a non-combat kind must not
+  omit substantive active combat, and a combat kind must be supported by such
+  combat. Keep the existing deterministic downstream rule that combat-turn
+  extraction runs only for an exact `combat` scene classification; semantic
+  review improves the upstream classification but does not replace that gate.
+- Run the semantic validator through PromptKit, use a minimal required-field
+  structured response schema, and let PromptKit repair structural validator
+  output within its bounded budget. A contract-invalid final validator response
+  is a validator execution failure, not a semantic rejection and not a reason
+  to recursively validate the validator.
+- Evaluate the prompt and decision policy against a small human-reviewed set
+  containing combat setup, active turns, interruptions, multi-phase encounters,
+  brief rules discussion, aftermath, recalled combat, and false-positive
+  hostile dialogue. Measure false acceptance, false rejection, retry success,
+  added calls, latency, and token cost before placing it in the production
+  default chain.
+- An ADR is not required if classification remains owned by
+  `dnd/scene-descriptions` and the validator follows the generic validation ADR.
+  Create or supersede an ADR if the work transfers scene classification into
+  the chunker or otherwise changes stage ownership or the durable chunk-plan
+  contract.
+
+### Warning Signal And Presentation Reform
+
+- Audit every warning producer and representative successful runs. Ordinary
+  success producing dozens of warnings is a failed operator experience: the
+  volume obscures actionable problems and trains operators to ignore the
+  warning channel.
+- Define a small warning taxonomy that distinguishes actionable degradation,
+  incomplete validation, lossy fallback, and data-quality risk from routine
+  normalization observations or informational diagnostics. Preserve detailed
+  traceability in debug or manifest data without promoting every observation
+  to a top-level CLI warning.
+- Consider stable deduplication and aggregation by scope and reason code,
+  bounded samples plus omitted counts, and a concise CLI summary with a path to
+  detailed diagnostics. Do not suppress genuine validator execution failures
+  merely to reduce the count.
+- Decide which warnings affect process status, rejection summaries, durable run
+  receipts, or only debug output. Ensure warning ordering and aggregation are
+  deterministic across concurrent execution.
+- Establish a representative warning-volume acceptance target and human review
+  workflow before changing individual producers piecemeal. The intended result
+  is not zero warnings; it is a small set in which every surfaced warning merits
+  operator attention.
+- This work does not require an ADR unless it changes validation acceptance,
+  failure, or durable contract semantics. CLI presentation and diagnostic
+  taxonomy otherwise belong in a feature roadmap followed by updates to their
+  canonical configuration, operations, integration, and internal documents.

 ## Shared Normalization And Quality Work
 
-### Generic LLM-Assisted Deduplication
+The implemented source-backed core and initial D&D registry adoption are
+described by [Module Internals](../internal/modules.md#semantic-reconciliation)
+and
+[D&D Module Internals](../internal/dnd.md#semantic-registry-reconciliation).
+The sections below keep broader extensions deferred.
 
-- Add a reusable normalizer that asks an LLM to identify duplicate sets in a
-  list and propose one replacement element for each set.
-- Define the minimum domain-neutral input contract, initially an ordered list
-  whose elements retain stable unique IDs as internal deterministic state.
-  Model proposals use contextual descriptors, or a specifically justified
-  request-local short label, rather than durable IDs. Artifact-kind
-  registrations or adapters may expose that structure without moving domain
-  rules into the generic package.
-- Keep mutation deterministic: parse and validate the model's duplicate groups,
-  resolve every supplied descriptor or local label exactly, reject overlapping
-  or malformed groups, prevent unrelated insertion or deletion, and apply only
-  approved replacement operations in code.
-- Preserve provenance needed for audit and downstream validation, and emit
-  warnings describing every collapsed group.
-- Evaluate batching and context-window limits before applying the normalizer to

+### Large-Collection Semantic Reconciliation
 
-The model may use its own domain knowledge to judge semantic duplication; the
-generic implementation is responsible only for the common proposal contract,

+- Evaluate deterministic candidate blocking only after representative registry
+  inputs exceed the active roadmap's bounded single-request limits. Blocking
+  should use cheap, explainable signals to form plausible comparison sets while
+  preserving the possibility that a duplicate appears outside a lexical name

+- Define correctness for candidates that appear in more than one block,
+  conflicting canonical selections, transitive identity across blocks, retry
+  isolation, and deterministic final ordering before implementation.
+- Prefer a reconciliation graph or union plan with explicit conflict checks
+  over arbitrary fixed-size slices. Never silently treat a batch boundary as
+  evidence that two candidates are distinct.
+- Record per-request bounds, block provenance, model calls, discarded
+  proposals, and final group derivation well enough to audit a collapse.
+
+### Operator-Selected Semantic Policies
+
+- Consider allowing an operator to select an approved semantic-policy prompt
+  for a typed reconciliation module without replacing the shared protocol,
+  response schema, or deterministic safety rules.
+- Define the trusted asset source, configuration syntax, compatibility checks,
+  startup validation, provenance, prompt fingerprinting, checkpoint effects,
+  and support boundary before exposing the option.
+- Prefer selection among registered, typed-policy-compatible prompt assets over
+  arbitrary filesystem prompt paths. Do not add this flexibility until an
+  operator workflow requires it; artifact-family-owned policy remains simpler
+  and safer for the initial implementation.
+
+### Broader Reconciliation Inputs And Module Selection
+
+- Revisit alternate context providers when a concrete non-source-backed entity
+  collection needs semantic reconciliation. Any extension must preserve the
+  same request-local identity, deterministic proposal validation, provenance,
+  and typed application guarantees.
+- Consider a selectable generic normalizer only if Notarius gains a real
