 # narratio
 
-`narratio` is a Go orchestration application for processing D&D session audio into transcripts and generated artifacts.
+Narratio is a Go orchestration application that turns D&D session audio into polished transcripts and generated session artifacts.
 
-## Current Implementation
+It coordinates transcription, merge/polish/normalize/trim processing, artifact generation, archive publishing, and resumable run state in one operator workflow.
-
-Implemented now:
-
-- strict config loading/validation (`pipeline.yml` and `session.yml`)
-- local workspace/session layout, locking, and manifest persistence
-- resumable stage control (`run`, `plan`, `resume`, `run-stage`, `status`)
-- real `prepare`, `transcribe`, `merge`, `polish`, `normalize`, `trim`, and `analyze` stages
-- real WhisperX, Seriatim, and Audita adapters
-- real Scriptorium subprocess adapter
-- optional Scriptorium render diagnostics (`render_debug`)
-
-Not implemented yet:
-
-- `archive` stage behavior
-- `notify` stage behavior
-- additional analyze artifacts beyond `session_recap`
-- generic DAG orchestration
-
-## Config Files
-
-Narratio expects two YAML files:
-
-- `pipeline.yml`: pipeline/workspace settings
-- `session.yml`: per-session settings
-
-Pipeline config lookup for CLI commands:
-
-- if `--config <path>` is provided, Narratio uses that path
-- if `--config` is omitted, Narratio searches in this order:
-  - `/usr/local/etc/narratio/pipeline.yml`
-  - `/etc/narratio/pipeline.yml`
-
-Optional secrets-from-files config:
-
-- `pipeline.secrets.env_dir` may point to a directory of secret files
-- each top-level file with an env-var-style name is loaded as an environment variable:
-  - file name = env var name
-  - file contents = env var value (trailing newline/CRLF trimmed)
-- process environment wins: existing env vars are not overwritten
-- if configured, Narratio fails fast when `env_dir` is missing/unreadable
-- relative `env_dir` values resolve from Narratio’s current working directory
-
-YAML decoding is strict (`KnownFields(true)`), so unknown fields fail fast.
-
-## Canonical Stage Order
-
-1. `prepare`
-2. `transcribe`
-3. `merge`
-4. `polish`
-5. `normalize`
-6. `trim`
-7. `analyze`
-8. `archive`
-9. `notify`
-
-## Transcript Tiers
-
-- `transcripts/merged.json`: canonical deterministic merged transcript from Seriatim merge
-- `transcripts/processed.json`: full raw Audita-polished transcript output
-- `transcripts/normalized.json`: Seriatim-normalized transcript from the normalize stage
-- `transcripts/trimmed.json`: gameplay-only normalized polished transcript from trim stage
-
-## Normalize Configuration
-
-`pipeline.normalize` is optional. When omitted, Narratio defaults to:
-
-- `output_path: transcripts/normalized.json`
-- `output_schema: seriatim-intermediate`
-- `report: true`
-
-Allowed `normalize.output_schema` values:
-
-- `seriatim-minimal`
-- `seriatim-intermediate`
-- `seriatim-full`
-
-`normalize.output_path` is treated as session-workdir-relative when not absolute.
-
-Normalize stage behavior summary:
-
-- normalize runs after `polish` and before `trim`
-- normalize resolves `transcripts/processed.json`
-- normalize runs Seriatim `normalize` to produce `transcripts/normalized.json`
-- normalize diagnostics are written to:
-  - `artifacts/seriatim.normalize.report.json` (when enabled)
-  - `logs/seriatim.normalize.stdout.log`
-  - `logs/seriatim.normalize.stderr.log`
-  - `config/seriatim.normalize.generated.yml`
-
-## Trim Configuration
-
-`pipeline.trim` is optional. If omitted, no trim config is loaded. If `trim.enabled` is omitted, it defaults to `false`.
-
-When `trim.enabled: true`:
-
-- `trim.output_path` is required
-- `trim.bounds.prompt_id` is required
-- `trim.bounds.transcript_input_name` is required
-- `trim.bounds.output_path` is required
-- `trim.bounds.timeout` must be a valid Go duration when provided
-- `trim.bounds.render_debug: true` requires `trim.bounds.render_output_path`
-- `trim.bounds.profile_id` may be empty to use the prompt default profile
-
-Trim paths are treated as session-workdir-relative when not absolute.
-
-Example trim config:
-
-```yaml
-trim:
-  enabled: true
-  output_path: "transcripts/trimmed.json"
-  bounds:
-    prompt_id: "dnd_session.bounds"
-    profile_id: ""
-    transcript_input_name: "transcript"
-    output_path: "artifacts/session_bounds.json"
-    timeout: "10m"
-    render_debug: false
-    render_output_path: "artifacts/session_bounds.render.json"
-  seriatim:
-    report: false
-```
-
-Trim behavior summary:
-
-- trim discovers and validates `transcripts/normalized.json`
-- trim uses Scriptorium bounds (`dnd_session.bounds` by example config) to produce `artifacts/session_bounds.json`
-- bounds IDs are validated against the same normalized transcript ID space that Seriatim trim will consume
-- trim converts bounds to Seriatim keep selector (for example `10-868`) and runs Seriatim trim
-- if trim is disabled, Narratio copies normalized transcript to trimmed transcript and records `trim_action=copy_disabled`
-
-Trim outputs and diagnostics:
-
-- `artifacts/session_bounds.json`
-- `transcripts/trimmed.json`
-- `logs/scriptorium.bounds.stdout.log`
-- `logs/scriptorium.bounds.stderr.log`
-- `config/scriptorium.bounds.generated.yml`
-- `logs/seriatim.trim.stdout.log`
-- `logs/seriatim.trim.stderr.log`
-- `config/seriatim.trim.generated.yml`
-- optional bounds render-debug outputs:
-  - `artifacts/session_bounds.render.json`
-  - `logs/scriptorium.bounds.render.stdout.log`
-  - `logs/scriptorium.bounds.render.stderr.log`
-  - `config/scriptorium.bounds.render.generated.yml`
-
-Render-debug files are diagnostics and are not treated as canonical stage output artifact refs.
-
-## Scriptorium Configuration
-
-`pipeline.scriptorium` is optional. When present, Narratio validates and uses it for analyze-stage artifact generation.
-
-Key points:
-
-- `scriptorium.binary` is required when section is present
-- `scriptorium.config_path` is optional
-- `scriptorium.timeout` defaults to `10m` when omitted
-- `scriptorium.render_debug` enables render diagnostics globally
-- artifacts are configured under `scriptorium.artifacts` (map shape supports multiple artifacts)
-- enabled artifacts require `prompt_id` and `output_path`
-- artifact `render_debug` may override global render setting
-- `vars` currently support boolean and string values
-
-Example `session_recap` artifact definition:
-
-```yaml
-scriptorium:
-  binary: "scriptorium"
-  config_path: "/etc/scriptorium/config.yml"
-  timeout: "10m"
-  render_debug: false
-
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: "dnd.session_recap"
-      profile_id: "local-quality" # optional
-      output_path: "artifacts/session_recap.md"
-      timeout: "10m"
-      # render_debug: true # optional per-artifact override
-
-      inputs:
-        transcript:
-          source: "trimmed_transcript"
-          required: true
-
-        previous_recap:
-          source: "previous_session_artifact"
-          artifact: "session_recap"
-          path: "" # optional; set when available
-          required: false
-
-      vars:
-        session_id: true
-        session_date: true
-        campaign_name: true
-        previous_session_id: true
-        output_kind: "session_recap"
-```
-
-Prompt IDs and profile IDs are configuration values. They are not hardcoded in analyze-stage logic.
-
-Do not put secrets in `pipeline.yml`. If API-key behavior is configured, use env var names only.
-
-If `pipeline.secrets.env_dir` is configured, keep only references and secret files there; secret values are still not written to manifests, generated configs, or Narratio-managed logs.
-
-## Scriptorium Runtime Behavior
-
-Narratio integrates with Scriptorium through the public CLI subprocess contract:
-
-- generation: `scriptorium run`
-- diagnostics/testing: `scriptorium render --format json` when `render_debug` is enabled
-
-For the initial implementation, only `session_recap` generation is supported.
-
-Analyze-stage session recap behavior:
-
-- available transcript input sources for configured artifacts: `processed_transcript`, `normalized_transcript`, `trimmed_transcript`
-- session recap should use gameplay-only transcript input (`source: trimmed_transcript`)
-- Narratio resolves `trimmed_transcript` from trim manifest output (`transcript_trimmed`) or fallback `transcripts/trimmed.json`
-- Narratio resolves `normalized_transcript` from normalize manifest output (`transcript_normalized`) or fallback `transcripts/normalized.json`
-- missing trimmed transcript fails clearly and advises running trim stage first
-- `normalized_transcript` is the preferred full-transcript source for future table/meta-analysis artifacts
-- `processed_transcript` remains supported for advanced/debug use cases
-- optionally includes `previous_recap` when configured and resolvable
-- omits optional previous recap when unavailable
-- fails if required inputs are missing
-- validates output file exists and is non-empty
-
-Expected session output paths:
-
-- `artifacts/session_recap.md`
-- `logs/scriptorium.session_recap.stdout.log`
-- `logs/scriptorium.session_recap.stderr.log`
-- `config/scriptorium.session_recap.generated.yml`
-- `artifacts/session_recap.render.json` when render diagnostics are enabled
-
-## Examples
-
-Starter files:
-
-- `examples/pipeline.minimal.yml`
-- `examples/session.minimal.yml`
-- `examples/speakers.yml`
-
-## Commands
-
-Run tests:
 
 ```bash
-go test ./...
+narratio run 2026-04-04
 ```
 
-Plan a run:
+This command requires discoverable `pipeline.yml` and `session.yml` files (or explicit `--config` and `--session` flags).
 
-```bash
+## Documentation
-go run ./cmd/narratio plan --session examples/session.minimal.yml
-```
 
-Use `--config <path>` to override default pipeline lookup when needed.
+- [Configuration](docs/config.md)
-
+- [CLI Reference](docs/cli.md)
-Run full pipeline:
+- [Operations and Recovery](docs/operations.md)
-
+- [Troubleshooting](docs/troubleshooting.md)
-```bash
+- [Development Guide](docs/development.md)
-go run ./cmd/narratio run --config examples/pipeline.minimal.yml --session examples/session.minimal.yml
+- [Architecture Principles](docs/architecture.md)
-```
+- [Internal Component Contracts](docs/internal/README.md)
-
+- [Config Examples](examples/)
-Run analyze only:
-
-```bash
-go run ./cmd/narratio run-stage --config examples/pipeline.minimal.yml --session examples/session.minimal.yml analyze
-```
-
-## Operational Note
-
-Checksum-based stale detection is not implemented yet.
-
-If prepared inputs or prompt/runtime config change, rerun the appropriate upstream stages before relying on downstream artifacts.
-
-Examples:
-
-- glossary/autocorrect/speaker-context changes: rerun at least `merge`, `polish`, `normalize`, `trim`, and `analyze`
-- trim bounds prompt/profile/config changes: rerun at least `normalize`, `trim`, and `analyze`
-- session recap prompt/profile/input-source changes: rerun `analyze`
-
-## Roadmap
-
-Near-term roadmap:
-
-- extend analyze to additional configured artifacts
-- support workflows where later artifacts consume earlier generated artifacts
-- keep orchestration explicit without a generic DAG engine
-- implement archive and notify backends

-# Narratio Architecture
-
-## 1. Purpose
-
-`narratio` is a Go orchestrator for D&D session processing. It runs a stage-based local pipeline from audio input through transcript processing and artifact generation, with manifest-based skip/force/resume behavior.
-
-Narratio integrates with Scriptorium through the **public CLI** (`scriptorium run` and `scriptorium render`) via synchronous subprocess execution.
-
-## 2. Current Status
-
-Implemented:
-
-- strict `pipeline.yml` + `session.yml` loading with strict YAML field checking (`KnownFields(true)`)
-- local workspace/session layout, lock file handling, artifact path helpers, checksums, and atomic writes
-- manifest store and stage status transitions for resumable runs
-- real `prepare`, `transcribe`, `merge`, and `polish` stages
-- real WhisperX HTTP adapter
-- real Seriatim subprocess adapter
-- real Audita subprocess adapter
-- real Scriptorium subprocess adapter
-- real `normalize` stage producing `transcripts/normalized.json`
-- real `trim` stage producing `transcripts/trimmed.json`
-- real `analyze` stage for initial `session_recap` generation
-- optional Scriptorium render diagnostics (`render_debug`) before production run
-
-Still placeholder/future:
-
-- `archive` stage behavior
-- `notify` stage behavior
-- additional Scriptorium artifact types beyond `session_recap`
-- artifact-to-artifact workflows beyond the initial single-artifact implementation
-- generic stale detection based on input/config checksums
-
-## 3. Pipeline and Stage Boundaries
-
-Canonical stage order:
-
-1. `prepare`
-2. `transcribe`
-3. `merge`
-4. `polish`
-5. `normalize`
-6. `trim`
-7. `analyze`
-8. `archive`
-9. `notify`
-
-Boundary rules:
-
-- orchestration logic lives in `internal/app`
-- stage business logic lives in `internal/stage`
-- external-tool CLI construction lives in adapter packages
-- Scriptorium CLI details stay in `internal/adapters/scriptorium`
-
-## 4. Scriptorium Integration Model
-
-Integration mode:
-
-- public CLI subprocesses only (no Scriptorium internal Go packages, no HTTP API)
-- production generation uses `scriptorium run`
-- diagnostics/testing render uses `scriptorium render --format json`
-
-Run invocation shape used by adapter:
-
-```bash
-scriptorium run --prompt <prompt_id> --input name=path --out <output_path>
-```
-
-Optional flags passed when configured:
-
-- `--config <path>`
-- `--profile <profile_id>`
-- repeated `--var name=value`
-- repeated `--input name=path`
-- `--timeout <duration>`
-- `--api-key-env <ENV_NAME>` when configured
-
-Render invocation shape used by adapter:
-
-```bash
-scriptorium render --prompt <prompt_id> --input name=path --format json --out <render_output_path>
-```
-
-Adapter behavior:
-
-- always passes `--out`
-- captures stdout/stderr separately
-- writes generated invocation metadata YAML (redacted, no secrets)
-- treats exit code `0` as success
-- treats exit code `1` as failure
-- treats exit code `2` as failure with `validation_failed=true` and preserves output metadata when available
-- validates successful output files exist and are non-empty
-- does not treat non-empty stderr as failure by itself
-
-## 5. Configuration Contract
-
-CLI pipeline config path resolution:
-
-- when `--config <path>` is provided, that path is used
-- when `--config` is omitted, Narratio searches defaults in order:
-  - `/usr/local/etc/narratio/pipeline.yml`
-  - `/etc/narratio/pipeline.yml`
-
-Optional pipeline secrets directory:
-
-- `pipeline.secrets.env_dir` enables loading environment variables from local files before command execution
-- file name = env var name; file contents = env var value (trailing newline/CRLF trimmed)
-- only env-var-style file names are considered; other entries are ignored
-- existing process environment values are preserved (not overwritten)
-- if configured, unreadable/missing `env_dir` fails command execution early
-- relative `env_dir` values are resolved from current working directory
-
-`pipeline.scriptorium` is optional. Existing pipelines without Scriptorium continue to work.
-
-`pipeline.trim` is optional. Existing pipelines without trim config continue to work.
-
-`pipeline.normalize` is optional. Existing pipelines without normalize config continue to work.
-
-When `pipeline.normalize` is omitted, defaults are applied:
-
-- `output_path: transcripts/normalized.json`
-- `output_schema: seriatim-intermediate`
-- `report: true`
-
-When `pipeline.normalize` is present:
-
-- `output_path` must be non-empty
-- `output_schema` must be one of `seriatim-minimal`, `seriatim-intermediate`, or `seriatim-full`
-- relative `output_path` values are session-workdir-relative paths
-- Seriatim binary settings still come from `pipeline.seriatim`
-
-When `pipeline.trim` is present:
-
-- `enabled` is optional and defaults to `false` when omitted
-- relative `output_path`, `bounds.output_path`, and `bounds.render_output_path` values are session-workdir-relative paths
-- do not store secrets in trim config values
-
-When `pipeline.trim.enabled: true`:
-
-- `output_path` is required and non-empty
-- `bounds.prompt_id` is required and non-empty
-- `bounds.transcript_input_name` is required and non-empty
-- `bounds.output_path` is required and non-empty
-- `bounds.timeout` must parse as a Go duration when provided
-- `bounds.render_debug: true` requires non-empty `bounds.render_output_path`
-- `bounds.profile_id` may be empty to use the prompt default profile
-- prompt IDs are config values, not hardcoded stage logic
-
-When `pipeline.scriptorium` is present:
-
-- `binary` is required and non-empty
-- `config_path` is optional; when provided it must be non-empty
-- `timeout` is optional; when provided it must parse as a Go duration
-- default `timeout` is `10m`
-- unknown YAML fields fail strict decode
-
-Artifacts are configured as a map under `pipeline.scriptorium.artifacts` so multiple artifacts are possible in the config shape.
-
-For each artifact definition:
-
-- `enabled: true` requires non-empty `prompt_id`
-- `enabled: true` requires non-empty `output_path`
-- `timeout` must parse as Go duration when present
-- optional per-artifact `render_debug` may override global `scriptorium.render_debug`
-- `inputs` are named and each input requires non-empty `source`
-- inputs may be optional (`required: false`)
-- `vars` values currently support `string` and `bool`
-
-Prompt IDs and profile IDs are configuration values, not hardcoded stage logic.
-
-Trim config shape:
-
-```yaml
-trim:
-  enabled: true
-  output_path: "transcripts/trimmed.json"
-  bounds:
-    prompt_id: "dnd_session.bounds"
-    profile_id: ""
-    transcript_input_name: "transcript"
-    output_path: "artifacts/session_bounds.json"
-    timeout: "10m"
-    render_debug: false
-    render_output_path: "artifacts/session_bounds.render.json"
-  seriatim:
-    report: false
-```
-
-## 6. Transcript Tiers
-
-Narratio currently produces and uses four transcript tiers:
-
-- `transcripts/merged.json`: canonical deterministic merged transcript from Seriatim merge
-- `transcripts/processed.json`: full raw Audita-polished transcript output (includes pre/post-game content)
-- `transcripts/normalized.json`: normalized transcript generated by Seriatim normalize
-- `transcripts/trimmed.json`: gameplay-only normalized polished transcript from trim stage
-
-Trim reads `transcripts/normalized.json`, validates bounds IDs against that same transcript ID space, and writes `transcripts/trimmed.json`.
-
-## 7. Normalize Stage (Current Implementation)
-
-Normalize stage behavior:
-
-- stage order position: after `polish` and before `trim`
-- discovers processed transcript from manifest polish outputs (`transcript_processed`) when present, else `work/<session_id>/transcripts/processed.json`
-- validates processed transcript JSON shape (`segments` array required)
-- runs Seriatim `normalize` to produce normalized transcript
-- validates normalized transcript JSON shape (`segments` array required)
-- validates normalize report JSON when enabled
-
-Expected normalize outputs and diagnostics:
-
-- `transcripts/normalized.json`
-- `artifacts/seriatim.normalize.report.json` (when normalize report is enabled)
-- `logs/seriatim.normalize.stdout.log`
-- `logs/seriatim.normalize.stderr.log`
-- `config/seriatim.normalize.generated.yml`
-
-## 8. Trim Stage (Current Implementation)
-
-Trim stage behavior:
-
-- stage order position: after `normalize` and before `analyze`
-- discovers normalized transcript from manifest normalize outputs (`transcript_normalized`) when present, else `work/<session_id>/transcripts/normalized.json`
-- validates normalized transcript JSON shape (`segments` array required)
-- when `trim.enabled: false` (or trim config omitted), deterministically copies normalized transcript to `transcripts/trimmed.json` and records `trim_action=copy_disabled`
-- when `trim.enabled: true`:
-  - runs Scriptorium bounds prompt using configured `trim.bounds.prompt_id`
-  - writes bounds output to configured path (typically `artifacts/session_bounds.json`)
-  - parses and validates bounds output against the same normalized transcript being trimmed
-  - converts bounds range to Seriatim keep selector (for example `10-868`)
-  - runs Seriatim `trim` to produce `transcripts/trimmed.json`
-  - supports no-trim bounds actions (`none`/`copy`) by copying normalized transcript unchanged
-- validates trimmed transcript JSON shape (`segments` array required)
-
-Expected trim outputs and diagnostics:
-
-- `artifacts/session_bounds.json`
-- `transcripts/trimmed.json`
-- `logs/scriptorium.bounds.stdout.log`
-- `logs/scriptorium.bounds.stderr.log`
-- `config/scriptorium.bounds.generated.yml`
-- `logs/seriatim.trim.stdout.log`
-- `logs/seriatim.trim.stderr.log`
-- `config/seriatim.trim.generated.yml`
-- optional bounds render-debug outputs when enabled:
-  - `artifacts/session_bounds.render.json`
-  - `logs/scriptorium.bounds.render.stdout.log`
-  - `logs/scriptorium.bounds.render.stderr.log`
-  - `config/scriptorium.bounds.render.generated.yml`
-
-Render-debug files are diagnostics. They are recorded in stage metadata/log/config refs and are not treated as canonical stage output artifact refs.
-
-## 9. Analyze Stage (Current Implementation)
-
-The current real analyze implementation supports only `scriptorium.artifacts.session_recap`.
-
-Behavior:
-
-- if `pipeline.scriptorium` is missing, analyze returns a skipped result with metadata
-- if no Scriptorium artifacts are enabled, analyze returns a skipped result with metadata
-- if enabled artifacts exist but `session_recap` is not enabled, analyze fails clearly
-- available transcript input sources for configured artifacts: `processed_transcript`, `normalized_transcript`, `trimmed_transcript`
-- `session_recap` should use `trimmed_transcript` input (`transcripts/trimmed.json`) for in-universe recap generation
-- `trimmed_transcript` input is resolved from manifest (`trim` output kind `transcript_trimmed`) when available, otherwise fallback path `work/<session_id>/transcripts/trimmed.json`
-- `normalized_transcript` input is resolved from manifest (`normalize` output kind `transcript_normalized`) when available, otherwise fallback path `work/<session_id>/transcripts/normalized.json`
-- `processed_transcript` input is resolved from manifest (`polish` output kind `transcript_processed`) when available, otherwise fallback path `work/<session_id>/transcripts/processed.json`
-- `normalized_transcript` is the preferred full-transcript source for future table/meta-analysis artifacts
-- `processed_transcript` remains available for advanced/debug use cases
-- transcript inputs are validated as JSON with top-level `segments` array
-- configured inputs are resolved by source
-- optional `previous_recap` is omitted when unavailable
-- required `previous_recap` fails before invocation when unavailable
-- vars are built from config + session metadata
-- `render_debug` controls pre-run `scriptorium render` diagnostics
-- render failure stops stage before production run
-- render output is validated as JSON
-- production call uses Scriptorium adapter `RunArtifact`
-- successful run output must exist and be non-empty
-- missing `trimmed_transcript` input for configured `trimmed_transcript` source fails clearly with guidance to run trim stage first
-- manifest records output refs, logs, generated config paths, and non-secret provenance metadata
-
-## 10. Session Recap Paths
-
-Current expected paths for `session_recap`:
-
-- artifact output: `artifacts/session_recap.md`
-- run stdout log: `logs/scriptorium.session_recap.stdout.log`
-- run stderr log: `logs/scriptorium.session_recap.stderr.log`
-- run generated invocation/config: `config/scriptorium.session_recap.generated.yml`
-- render output (when enabled): `artifacts/session_recap.render.json`
-- render stdout log: `logs/scriptorium.session_recap.render.stdout.log`
-- render stderr log: `logs/scriptorium.session_recap.render.stderr.log`
-- render generated invocation/config: `config/scriptorium.session_recap.render.generated.yml`
-
-## 11. Security and Privacy
-
-- do not store secrets in pipeline YAML, generated invocation YAML, logs, or manifest metadata
-- if API-key integration is configured, pass env var names only (never raw key values)
-- with `pipeline.secrets.env_dir`, secret file values are loaded into process env only and are not persisted in manifest metadata or generated configs
-- avoid logging transcript content or rendered prompt content by default
-- treat generated artifacts and logs as potentially sensitive session material
-
-## 12. Operational Caveat (Pre-Stale-Detection)
-
-Checksum-based stale detection is not implemented yet.
-
-If prepared inputs or prompt/runtime configuration change (for example glossary files, prompt IDs, profile IDs, or relevant pipeline settings), rerun the appropriate prior stages to refresh downstream artifacts.
-
-Examples:
-
-- glossary or autocorrect changes usually require rerunning at least `merge`, `polish`, `normalize`, `trim`, and `analyze`
-- trim prompt/profile changes require rerunning at least `normalize`, `trim`, and `analyze`
-- session recap prompt/profile/input-source changes require rerunning `analyze`
-
-## 13. Roadmap
-
-Planned next steps:
-
-- extend analyze beyond `session_recap` to additional configured artifacts
-- support artifact inputs that consume prior generated artifacts
-- keep this composable without adding a generic DAG engine in the near term
-- implement real `archive` backend behavior
-- implement real `notify` backend behavior
-- add checksum-based stale detection and stale transitions
-
-Architectural invariants remain:
-
-- strict config decoding/validation
-- manifest-driven run control
-- clear stage/adapter separation
-- configuration-driven prompt/profile/input/vars/output mapping
-- Scriptorium integration through public CLI subprocess contract

+# Narratio Architecture
+
+## Purpose
+
+`narratio` is a Go orchestration application for processing D&D session audio into polished transcripts and generated session artifacts.
+
+This document defines the development principles for the project. It is inward-facing: its audience is developers and LLM coding agents. It should guide future changes, not serve as a complete implementation reference.
+
+Implemented component details belong under `docs/internal/`.
+
+## Project Shape
+
+Narratio is a modular, stage-driven orchestrator.
+
+It coordinates specialized downstream systems rather than reimplementing their domains:
+
+- WhisperX handles transcription.
+- Seriatim handles deterministic transcript merge/normalization/trim behavior.
+- Audita handles transcript correction and polishing.
+- Scriptorium handles prompt execution and generated artifacts.
+
+Narratio owns orchestration, configuration loading, session/run state, local and remote path modeling, manifest persistence, stage sequencing, resume behavior, and archive semantics.
+
+Narratio should remain explicit and comprehensible. It is not intended to become a generic workflow engine.
+
+## Core Principles
+
+### Modular and composable
+
+Code should be organized around clear responsibilities. Stages, adapters, config loading, manifest persistence, path construction, and storage behavior should remain separable and independently testable.
+
+### Hexagonal boundaries
+
+External systems should be isolated behind narrow adapters. Stage logic should depend on Narratio-level interfaces and data structures, not on external SDK types, subprocess argument construction, or transport-specific details.
+
+### Standard library preference
+
+Prefer the Go standard library. Add dependencies only when they provide substantial value, are necessary for an external integration, or are a widely used de facto standard.
+
+Accepted examples include a YAML library for configuration and the AWS SDK for S3-compatible storage.
+
+### Explicit orchestration
+
+The pipeline should remain stage-driven and explicit. New behavior should be added through clear stage, adapter, config, or manifest contracts rather than implicit side effects or generic workflow abstraction.
+
+## Stage Design
+
+Each stage should have a clear scope of responsibility.
+
+A stage should define:
+
+- its purpose;
+- required input state;
+- produced output state;
+- config fields it consumes;
+- external adapters it uses;
+- manifest refs it reads or writes;
+- skip, force, and resume behavior;
+- failure behavior;
+- tests that protect its contract.
+
+Stages should avoid reaching across boundaries. If shared behavior is needed, prefer a helper or service with a narrow interface over duplicating ad hoc logic between stages.
+
+## Transactionality and Resume
+
+A stage should behave transactionally.
+
+A stage is complete only when its outputs have been written, validated, and recorded in the manifest. If a stage fails, Narratio should preserve enough local state for inspection, recovery, and resume.
+
+A failed or incomplete run must not be treated as successful. Later stages should depend on manifest-recorded success, not merely on incidental files existing on disk.
+
+## Manifest Model
+
+The manifest is the durable local ledger for a run.
+
+It should record:
+
+- run identity;
+- stage status;
+- input and output refs;
+- logs and generated config refs;
+- checksums or provenance where useful;
+- non-secret adapter and archive metadata.
+
+Resume behavior should be manifest-driven. Filesystem state may be inspected and validated, but it should not replace manifest stage state as the source of run progress.
+
+## Adapter Boundaries
+
+Adapters own external integration details.
+
+Expected boundaries:
+
+- WhisperX HTTP details stay in the WhisperX adapter.
+- Seriatim CLI construction stays in the Seriatim adapter.
+- Audita CLI construction stays in the Audita adapter.
+- Scriptorium CLI construction stays in the Scriptorium adapter.
+- Object-storage details stay behind the storage adapter interface.
+- AWS SDK types stay inside the S3 storage implementation.
+
+Stage code should express intent in Narratio terms and call adapters through narrow contracts.
+
+## Configuration Philosophy
+
+Configuration should be strict, explicit, and operator-friendly.
+
+Principles:
+
+- YAML decoding should reject unknown fields.
+- Defaults should be centralized and testable.
+- Empty configured values should not silently override meaningful defaults.
+- Session templating should remain narrow and deterministic.
+- Template support should serve operator convenience, not become a general configuration language.
+
+Narratio should not become a secondary configuration system for downstream tools. Seriatim, Audita, and Scriptorium should own their runtime defaults wherever practical. Narratio should pass required stage-contract paths and explicit operator overrides.
+
+## Path and Storage Discipline
+
+Local and remote paths are part of Narratio’s application contract.
+
+Code should use centralized path helpers for workspace, spool, session, run, artifact, log, config, and archive paths. Stages should avoid reconstructing canonical paths through scattered string concatenation.
+
+Storage backends should receive explicit bucket-relative keys. Storage implementations should not infer campaign, session, run, or root-prefix semantics.
+
+## Archive Invariants
+
+Archive behavior must preserve a clear commit boundary.
+
+A remote run is current only after the archive stage has successfully uploaded the run record, required promoted outputs, `current/manifest.json`, and finally `current/run_id.txt`.
+
+`current/run_id.txt` is the final remote commit marker and must be written last.
+
+Failed, incomplete, skipped, or uncommitted archive attempts must not be presented as current remote state. Local cleanup is permitted only after successful archive commit and only when explicitly configured.
+
+## Security and Privacy
+
+Narratio handles private campaign material.
+
+Rules:
+
+- Do not store raw secrets in pipeline or session YAML.
+- Use environment variable names or secret-file references for secret handling.
+- Do not write raw secret values to manifests, logs, generated configs, or archive metadata.
+- Treat transcripts, generated artifacts, prompts, reports, and logs as potentially sensitive.
+- Avoid logging transcript or prompt content unless there is a deliberate diagnostic reason.
+
+## Diagnostics
+
+Diagnostics should be durable and discoverable, but distinct from canonical outputs.
+
+Logs, reports, generated invocation/config files, and render-debug files support debugging. Transcript tiers and configured artifacts are pipeline products.
+
+Manifest refs should preserve that distinction.
+
+## Determinism
+
+Where practical, Narratio should prefer deterministic behavior:
+
+- stable local path layout;
+- stable remote key layout;
+- sorted upload order;
+- predictable generated config files;
+- repeatable command construction;
+- tests that do not depend on live external services.
+
+Run IDs and timestamps may be intentionally variable, but surrounding behavior should remain testable.
+
+## Testing Expectations
+
+Core behavior should be testable without live external services.
+
+Tests should cover:
+
+- config loading, defaults, and validation;
+- CLI parsing and command construction;
+- path helpers;
+- manifest transitions;
+- stage success, failure, skip, and resume behavior;
+- adapter command construction;
+- fake storage behavior;
+- archive commit ordering;
+- example config validity where practical.
+
+Live S3, WhisperX, LLM, or subprocess integration tests should be explicit integration tests, not required for ordinary unit test runs.
+
+## Documentation Expectations
+
+Documentation must follow `docs/documentation/policy.md`.
+
+Current behavior belongs in user-facing docs and `docs/internal/`. Future, planned, aspirational, experimental, or unimplemented work belongs only under `docs/roadmap/`.
+
+`docs/architecture.md` should remain concise and principle-focused. It should not duplicate the full config reference, CLI reference, operations guide, or internal stage documentation.
+
+## Non-Goals
+
+Narratio is not:
+
+- a generic DAG or workflow engine;
+- a replacement configuration layer for Seriatim, Audita, or Scriptorium;
+- a storage backend abstraction beyond the needs of this pipeline;
+- a place to embed raw secrets;
+- a place for stage logic to depend directly on AWS SDK types or downstream tool internals;
+- a prompt-authoring system.

+# CLI
+
+## Shortest Useful Command
+
+```bash
+narratio run 2026-04-04
+```
+
+This command uses default system discovery for `pipeline.yml`, the pipeline default campaign ID, and local `session.yml`. If local session discovery misses and S3 storage is configured, the positional session ID loads remote `session.yml` from the canonical session prefix.
+
+Default pipeline and session discovery checks system config locations only. Pass `--config`, `--campaign-file`, and `--session` to use files from the current working directory. Pass `--campaign <id>` to select a campaign from `pipeline.campaigns.root`.
+
+Ordinary local and remote `session.yml` files must be concrete YAML. Templates belong to `narratio session init`, which renders a configured campaign template before writing the concrete file.
+
+## Command Overview
+
+Top-level commands:
+
+- `run <session_id>`: execute pipeline stages and persist manifest state.
+- `run-stage <stage> <session_id>`: execute exactly one stage.
+- `resume <session_id>`: continue from first non-succeeded stage unless forced.
+- `analyze <session_id>`: force-rerun the analyze stage.
+- `publish <session_id>`: force-rerun the archive stage.
+- `clean <session_id>|--all`: remove local workspace/spool state.
+- `session <subcommand>`: session-scoped helper commands.
+
+Session subcommands:
+
+- `session init <session_id>`: create local or remote `session.yml`.
+- `session validate <session_id>`: run read-only preflight checks.
+- `session status <session_id>`: inspect local/remote session state.
+- `session plan <session_id>`: validate config, prepare workspace layout, and print stage run/skip decisions.
+- `session restore <session_id>`: restore durable local state from committed remote archive state.
+- `session artifacts <session_id>`: list effective artifact source IDs.
+- `session locks <session_id>`: list archive promotion locks.
+- `session locks add <session_id> <source>`: add or update a remote lock.
+- `session locks remove <session_id> <source>`: remove a remote lock.
+
+Unknown commands print usage and exit non-zero.
+
+For config semantics, see [docs/config.md](./config.md). For operator lifecycle and recovery, see [docs/operations.md](./operations.md).
+
+## Common Flags
+
+Most session-aware commands accept:
+
+- `--config <path>`: optional explicit `pipeline.yml` path.
+- `--campaign <id>`: optional campaign ID selector.
+- `--campaign-file <path>`: optional explicit `campaign.yml` path.
+- `--session <path>`: optional explicit concrete `session.yml` path.
+- `--previous-session-id <value>`: expected previous session identifier.
+
+The positional `<session_id>` is required even when `--session` is provided. It is used as the expected session identity and as the remote session lookup value when local session discovery misses.
+
+## Command Reference
+
+### `run`
+
+```bash
+narratio run <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--force] [--artifacts <name[,name...]>]
+```
+
+Purpose:
+- Execute configured stages in canonical order.
+
+Success output:
+- `narratio run: session <session_id>; executed=<n> skipped=<n>; manifest=<path>`
+
+Common failure cases:
+- missing system default config/session paths when flags are omitted.
+- missing selected campaign under `pipeline.campaigns.root`.
+- missing local session plus missing/unavailable remote `session.yml`.
+- templated `session.yml`; run `narratio session init` to generate concrete YAML.
+- concrete session identity mismatch.
+- unknown configured artifact key in `--artifacts`.
+
+### `resume`
+
+```bash
+narratio resume <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--force] [--artifacts <name[,name...]>]
+```
+
+Purpose:
+- Continue from session-manifest stage status.
+
+Success output:
+- `narratio resume: session <session_id> has no remaining stages`
+- or `narratio resume: session <session_id>; executed=<n> skipped=<n>; manifest=<path>`
+
+### `run-stage`
+
+```bash
+narratio run-stage <stage> <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--force] [--artifacts <name[,name...]>]
+```
+
+Valid stage names:
+
+- `prepare`
+- `transcribe`
+- `merge`
+- `polish`
+- `normalize`
+- `trim`
+- `analyze`
+- `archive`
+- `notify`
+
+Success output:
+- `narratio run-stage: stage=<name> executed=<n> skipped=<n> force=<true|false>; manifest=<path>`
+
+`--artifacts` is accepted only for `analyze` and `archive`.
+
+### `analyze`
+
+```bash
+narratio analyze <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--artifacts <name[,name...]>]
+```
+
+Purpose:
+- Force-rerun the analyze stage.
+- Shorter equivalent for `narratio run-stage analyze <session_id> --force`.
+
+`analyze` is force-by-design and does not accept `--force`.
+
+### `publish`
+
+```bash
+narratio publish <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--artifacts <name[,name...]>]
+```
+
+Purpose:
+- Force-rerun the archive stage.
+- Shorter equivalent for `narratio run-stage archive <session_id> --force`.
+
+`publish` is force-by-design and does not accept `--force` or a stage positional argument.
+
+### `clean`
+
+```bash
+narratio clean <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--dry-run] [--clear-cache]
+narratio clean --all [--config <pipeline.yml>] [--dry-run] [--clear-cache]
+```
+
+Session cleanup deletes:
+- `{workspace.root}/work/{campaign}/{session_id}`
+- `{spool.root}/{campaign}/{session_id}`
+
+All-session cleanup deletes:
+- `{workspace.root}/work`
+- the contents of `{spool.root}`, while preserving the spool root directory itself.
+
+Cache behavior:
+- cache is preserved by default.
+- `--clear-cache` in session mode removes cached S3 audio files for the resolved session.
+- `--all --clear-cache` removes the configured Narratio S3 audio cache namespace for the configured bucket/root prefix.
+- `--clear-cache` does not delete arbitrary files under `pipeline.cache.root`.
+
+### `session plan`
+
+```bash
+narratio session plan <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--force]
+```
+
+Purpose:
+- Validate config, load secrets if configured, prepare workdir, and print stage run/skip decisions.
+
+Success output includes:
+- `narratio session plan: workdir prepared at <path>`
+- one line per stage (`<stage>: run|skip`)
+- `totals: run=<n> skip=<n>`
+
+### `session status`
+
+```bash
+narratio session status <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+```
+
+Output includes:
+- session ID, campaign, workspace, and session config source.
+- local manifest state when present.
+- remote current archive state when storage is configured.
+- catalog-based promoted output availability for expected transcript and artifact sources.
+- effective archive locks and conservative next actions.
+
+### `session validate`
+
+```bash
+narratio session validate <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+```
+
+Checks include:
+- effective config and session source.
+- stable input files.
+- local or remote audio availability.
+- previous-session requirements.
+- archive promotions and effective locks.
+
+Warnings do not fail the command. Any `ERROR` finding exits non-zero.
+
+### `session init`
+
+```bash
+narratio session init <session_id> --output ./session.yml
+narratio session init <session_id> --remote
+narratio session init <session_id> --config <pipeline.yml> --campaign icewind --remote
+narratio session init <session_id> --config <pipeline.yml> --campaign-file ./campaign.yml --remote
+```
+
+Additional flags:
+
+- `--previous-session-id <value>`
+- `--date <value>`
+- `--title <value>`
+- `--audio-s3-prefix <prefix>`: defaults to `audio/` when neither audio flag is provided.
+- `--audio-dir <path>`: local audio directory; mutually exclusive with `--audio-s3-prefix`.
+- `--force`: overwrite existing local or remote target.
+
+Behavior:
+- exactly one of `--output` or `--remote` is required.
+- `--config`, `--campaign`, and `--campaign-file` are optional overrides; omitted campaign selection uses `pipeline.campaigns.default_campaign_id`.
+- `--campaign <id>` selects a campaign under `pipeline.campaigns.root`.
+- `--campaign-file <path>` loads an explicit campaign file.
+- if `campaign.yml` sets `session_template_file`, the template path is resolved relative to `campaign.yml` and rendered from init flags.
+- if no session template is configured, a minimal concrete session file is generated directly.
+- template variables must be supplied by matching flags, and supplied template-related flags must be used by the template.
+- remote writes target `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/session.yml`.
+- existing local or remote targets fail unless `--force` is passed.
+- remote writes use existence checks, not compare-and-swap.
+
+### `session restore`
+
+```bash
+narratio session restore <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--dry-run] [--force] [--include-audio]
+```
+
+Purpose:
+- Restore durable session state from the committed remote archive current state.
+- Default restore installs `manifest.json`, `transcripts/**`, and `artifacts/**` from the current session archive.
+- When configured previous-session inputs require it, restore reconstructs `previous/**` from the previous session's committed current archive.
+- `audio/**` is restored only with `--include-audio`.
+
+Dry-run output may include planned previous-cache downloads. Existing differing files under `previous/**` follow the normal restore conflict policy and require `--force` to overwrite.
+
+When `--include-audio` is set, S3 audio files are restored through the shared audio cache. Cache hits avoid re-downloading large audio objects.
+
+### `session artifacts`
+
+```bash
+narratio session artifacts <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--remote]
+```
+
+Purpose:
+- List built-in, configured, previous-session, promoted, and locked artifact sources.
+
+`--remote` checks promoted top-level object availability through the storage adapter. Remote markers appear only in the `Promoted` section, which reports each configured archive promotion destination and includes `dest=<path>` when that destination differs from the source's canonical path.
+
+### `session locks`
+
+```bash
+narratio session locks <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+narratio session locks add <session_id> <source> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--reason <text>] [--force]
+narratio session locks remove <session_id> <source> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+```
+
+Behavior:
+- list mode prints effective locks from static `pipeline.archive.locks` and remote `{session_prefix}/locks.yml`.
+- `locks add` writes only the remote lock store and fails if the source is already locked by pipeline config.
+- `locks remove` removes only remote locks and cannot remove static pipeline locks.
+- `locks add --force` is required to update an existing remote lock reason.
+
+## Common Workflows
+
+Default-discovery run:
+
+```bash
+narratio run 2026-04-04
+```
+
+Run only selected analyze artifacts:
+
+```bash
+narratio run 2026-04-04 --artifacts session_recap,player_handout
+```
+
+Resume with selected analyze artifacts:
+
+```bash
+narratio resume 2026-04-04 --artifacts player_handout
+```
+
+Force-rerun analyze with selected artifacts:
+
+```bash
+narratio analyze 2026-04-04 --artifacts player_handout
+```
+
+Force-rerun archive publishing:
+
+```bash
+narratio publish 2026-04-04
+```
+
+Preview restore actions without writes:
+
+```bash
+narratio session restore 2026-04-04 --dry-run
+```
+
+Restore and then force analyze:
+
+```bash
+narratio session restore 2026-04-04
+narratio analyze 2026-04-04
+```
+
+Rehydrate canonical previous-session inputs after artifact-input changes:
+
+```bash
+narratio run-stage prepare 2026-04-04 --force
+```
+
+Reset local state before testing restore:
+
+```bash
+narratio clean 2026-04-04 --dry-run
+narratio clean 2026-04-04
+narratio session restore 2026-04-04 --include-audio
+```
+
+Clean all local sessions while keeping cached S3 audio:
+
+```bash
+narratio clean --all
+```
+
+## `--artifacts` and `--force`
+
+- `--artifacts` filters which configured artifacts are executable when analyze runs and which configured artifact promotions archive publishes.
+- `--artifacts` does not imply `--force`.
+- if analyze is already `succeeded` and `--force` is not set, runner-level skip still applies.
+- `--artifacts` does not suppress built-in transcript or bounds promotions.

+# Configuration
+
+## 1. Overview
+
+Narratio loads three YAML files:
+
+- `pipeline.yml`: pipeline-level runtime configuration.
+- `campaign.yml`: stable campaign identity and campaign-level input defaults.
+- `session.yml`: per-session metadata and input selection, loaded locally or from the configured S3 backend.
+
+These commands load and validate all three files before running:
+
+- `narratio run`
+- `narratio resume`
+- `narratio run-stage`
+- `narratio analyze`
+- `narratio publish`
+- `narratio session plan`
+- `narratio session status`
+- `narratio session validate`
+- `narratio session restore`
+- `narratio session artifacts`
+- `narratio session locks`
+- `narratio clean <session_id>`
+
+Behavior:
+
+- strict YAML decode is enabled (`KnownFields(true)`): unknown fields fail.
+- ordinary local and remote `session.yml` files must be concrete YAML; template placeholders are rejected.
+- defaults are applied for optional pipeline fields.
+- campaign identity is selected by ID from the pipeline campaign registry unless `--campaign-file` is used.
+- campaign-level stable input paths fill missing session input paths.
+- session-level stable input paths override campaign-level input paths.
+- campaign config may point `session init` to a session template.
+- validation enforces required fields, value formats, and cross-field constraints.
+
+## 2. Config file discovery
+
+These commands use the same config discovery behavior:
+
+- `narratio run`
+- `narratio resume`
+- `narratio run-stage`
+- `narratio analyze`
+- `narratio publish`
+- `narratio session plan`
+- `narratio session status`
+- `narratio session validate`
+- `narratio session restore`
+- `narratio session artifacts`
+- `narratio session locks`
+- `narratio clean <session_id>`
+
+Pipeline config lookup:
+
+- if `--config <path>` is provided, that path is used.
+- if omitted, Narratio searches in order:
+  1. `/usr/local/etc/narratio/pipeline.yml`
+  2. `/etc/narratio/pipeline.yml`
+- first existing file wins.
+
+Campaign config lookup:
+
+- pipeline config is loaded first.
+- if `--campaign-file <path>` is provided, that path is used.
+- otherwise, if `--campaign <id>` is provided, Narratio loads:
+  - `{pipeline.campaigns.root}/{id}/campaign.yml`
+- otherwise, Narratio uses `pipeline.campaigns.default_campaign_id` and loads:
+  - `{pipeline.campaigns.root}/{default_campaign_id}/campaign.yml`
+- `--campaign` and `--campaign-file` are mutually exclusive.
+- campaign IDs must be single path segments, not paths.
+
+Session config lookup:
+
+- if `--session <path>` is provided, that path is used.
+- if `--session` is omitted, Narratio searches locally in order:
+  1. `/usr/local/etc/narratio/session.yml`
+  2. `/etc/narratio/session.yml`
+- first existing local file wins.
+- if no local session file is found, a positional `<session_id>` is present, storage is configured, and campaign identity is resolved, Narratio loads remote `session.yml` from:
+  - `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/session.yml`
+- local discovery always runs before remote fallback.
+- local files in the current working directory are used only when passed explicitly, for example `--config ./pipeline.yml --campaign-file ./campaign.yml --session ./session.yml`.
+
+## 3. Session templating
+
+Template behavior for local and remote `session.yml` loaded by downstream commands:
+
+- downstream commands do not render templates.
+- local and remote `session.yml` must be concrete.
+- any `{{ ... }}` placeholder in loaded `session.yml` fails with guidance to run `narratio session init`.
+- if concrete `session_id` mismatches the positional `<session_id>`, load fails.
+- if concrete `previous_session_id` mismatches `--previous-session-id`, load fails.
+
+Template behavior for `narratio session init`:
+
+- `campaign.yml` may set `session_template_file`.
+- relative template paths resolve relative to `campaign.yml`.
+- supported init template variables:
+  - `{{ session_id }}`
+  - `{{ previous_session_id }}`
+  - `{{ date }}`
+  - `{{ title }}`
+  - `{{ audio_s3_prefix }}`
+  - `{{ audio_dir }}`
+- each template variable must be supplied by the matching `session init` flag.
+- template-related flags such as `--date`, `--title`, `--audio-s3-prefix`, `--audio-dir`, and `--previous-session-id` fail if the configured template does not use them.
+- rendered output is strict-decoded and validated before it is written locally or remotely.
+- if `session_template_file` is omitted, `session init` generates the minimal concrete session YAML directly.
+
+## 4. Minimal config set
+
+### `pipeline.yml`
+
+```yaml
+campaigns:
+  root: /usr/local/share/narratio/campaigns
+  default_campaign_id: sample-campaign
+whisperx:
+  transcribe_url: "https://transcription.example.com/transcribe"
+```
+
+Why this is sufficient:
+
+- `whisperx.transcribe_url` is required.
+- `campaigns.default_campaign_id` selects the default campaign when `--campaign` is omitted.
+- `workspace.root` defaults to `/var/lib/narratio`.
+- optional sections (`seriatim`, `audita`, `archive`, `scriptorium`, `trim`, `normalize`, etc.) receive defaults or stay inactive.
+
+### `campaign.yml`
+
+```yaml
+campaign_id: sample-campaign
+session_template_file: ./session.template.yml
+inputs:
+  speakers_file: ./speakers.yml
+  autocorrect_file: ./autocorrect.yml
+  glossary_file: ./glossary.yml
+```
+
+Why this is sufficient:
+
+- `campaign_id` supplies the stable campaign identity.
+- stable input files are required and resolve relative to `campaign.yml` when copied during `prepare`.
+
+### `session.yml`
+
+```yaml
+session_id: 2026-05-03
+inputs:
+  audio_dir: ./audio
+```
+
+Why this is sufficient:
+
+- `session_id` is required.
+- `campaign` can be omitted because it is supplied by `campaign.yml`.
+- stable input paths can be omitted because `campaign.yml` supplies defaults.
+- local `audio_dir` resolves relative to `session.yml`.
+
+Minimal local-file usage:
+
+```bash
+narratio run 2026-05-03 --config /path/to/pipeline.yml --campaign sample-campaign --session ./session.yml
+narratio run 2026-05-03 --config /path/to/pipeline.yml --campaign-file ./campaign.yml --session ./session.yml

+
+Operational notes:
+
+- archive promotion is explicit and source-based via `archive.promote_artifacts`.
+- `source` is required; `dest` is optional and derived when omitted.
+- `archive.locks` skips top-level promotion overwrites for static locked sources while preserving run-local uploads.
+- operator-created mutable locks are stored at `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/locks.yml` and are merged with static locks.
+- Narratio does not auto-promote all generated analyze artifacts.
+- `restore` reads the same config/campaign/session inputs and restore scope is bounded by committed archive current state.
+- `clean` removes workspace/spool state by default and preserves `pipeline.cache.root` unless `--clear-cache` is passed.

+
+Scriptorium artifact-key and dependency rules:
+
+- artifact keys must match `^[a-z][a-z0-9_]*$`.
+- enabled artifacts require `prompt_id` and `output_path`.
+- `output_path` must be relative, traversal-safe, and under `artifacts/`.
+- configured artifact input sources use `narratio.artifact.<name>`.
+- if input source references `narratio.artifact.<name>`, artifact `<name>` must exist and must be listed in `depends_on`.
+- every `depends_on` entry must be a configured artifact key.
+- self-dependency is rejected.
+- enabled dependency cycles are rejected.
+- any artifact referenced by `depends_on` or `narratio.artifact.<name>` source must define `output_path` (even if not enabled).
+
+Allowed `pipeline.scriptorium.artifacts.<name>.inputs.<key>.source` values:
+
+- `narratio.previous_session.artifact.<configured_artifact_key>`
+- `narratio.transcript.base`
+- `narratio.transcript.polished`
+- `narratio.transcript.final`
+- `narratio.transcript.final_trimmed`
+- `narratio.bounds.session`
+- `narratio.artifact.<configured_artifact_key>`
+
+`pipeline.archive.promote_artifacts[].source` values:
+
+- `narratio.transcript.base`
+- `narratio.transcript.polished`
+- `narratio.transcript.final`
+- `narratio.transcript.final_trimmed`
+- `narratio.bounds.session`
+- `narratio.artifact.<configured_artifact_key>`
+
+`pipeline.archive.locks[].source` accepts the same source values as `pipeline.archive.promote_artifacts[].source`.
+
+Archive promotion destination rules:
+
+- `dest` must be a clean relative path (not absolute, no traversal).
+- duplicate `dest` values are rejected.
+- if `dest` is omitted:
+  - built-in sources derive their canonical destination path;
+  - configured sources derive from `pipeline.scriptorium.artifacts.<name>.output_path`;
+  - derivation failure is a config validation error.
+
+Archive lock rules:
+
+- locks are source-based and do not accept `dest`.
+- duplicate lock sources are rejected.
+- static `pipeline.archive.locks` win over remote mutable locks for the same source.
+- locked promotions are recorded as intentional skips in archive metadata.
+- locked required promotions do not fail archive by default.
+- ordinary `--force` reruns do not override locks.
+
+Remote mutable lock store:
+
+- path: `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/locks.yml`.
+- strict YAML shape: top-level `locks`, each with `source` and optional `reason`.
+- `narratio session locks add` and `narratio session locks remove` mutate only the remote lock store.
+- writes use existence checks plus `--force` for updates; they are not compare-and-swap atomic.
+
+Restore-related implications:
+
+- restore remote identity requires archive S3 identity to resolve (`pipeline.storage.s3.bucket` and session prefix derivation inputs).
+- restore scope considers committed current state and durable paths (`manifest.json`, `transcripts/**`, `artifacts/**`, `previous/**`, optional `audio/**`).
+- S3 audio downloads use `pipeline.spool.root` for active downloads and `pipeline.cache.root` for reusable cached audio when `pipeline.cache.s3_audio` is true.
+- `pipeline.cache.root` is durable local cache state. It is not workspace state and is preserved by default by `narratio clean`.
+
+## 7. Full campaign reference
+
+| Path | Type | Required | Default |
+| --- | --- | --- | --- |
+| `campaign.campaign_id` | string | Yes | none |
+| `campaign.session_template_file` | string | No | none |
+| `campaign.inputs.speakers_file` | string | Yes | none |
+| `campaign.inputs.autocorrect_file` | string | Yes | none |
+| `campaign.inputs.glossary_file` | string | Yes | none |
+
+Campaign input paths and `campaign.session_template_file` may be absolute or relative. Relative paths resolve from the directory containing `campaign.yml`.
+
+## 8. Full session reference
+
+| Path | Type | Required | Default |
+| --- | --- | --- | --- |
+| `session.session_id` | string | Yes | none |
+| `session.previous_session_id` | string | No | empty |
+| `session.campaign` | string | No | `campaign.campaign_id` |
+| `session.date` | string | No | empty |
+| `session.title` | string | No | empty |
+| `session.inputs.audio_dir` | string | Conditional | empty |
+| `session.inputs.audio_files[]` | list[string] | Conditional | empty |
+| `session.inputs.audio_s3.prefix` | string | Conditional | none |
+| `session.inputs.speakers_file` | string | No | `campaign.inputs.speakers_file` |
+| `session.inputs.autocorrect_file` | string | No | `campaign.inputs.autocorrect_file` |
+| `session.inputs.glossary_file` | string | No | `campaign.inputs.glossary_file` |
+
+Session input paths may be absolute or relative. Relative audio paths and session-level stable input overrides resolve from the directory containing `session.yml`. If both `campaign.yml` and `session.yml` specify campaign identity, the values must match.
+
+Audio-source rule:
+
+- configure exactly one mode:
+  - `audio_dir`, or
+  - `audio_files` (at least one), or
+  - `audio_s3.prefix`
+- `audio_s3` cannot be combined with local audio fields.
+
+Previous-session rule:
+
+- if `session.previous_session_id` is set, it must not equal `session.session_id`.
+- canonical previous-session sources (`narratio.previous_session.artifact.<name>`) are hydrated during `prepare` from archive current state when required by enabled configured artifacts.
+
+## 9. Secrets
+
+Narratio supports filesystem-based secret injection via `pipeline.secrets.env_dir`.
+
+Behavior:
+
+- `env_dir` may be absolute or relative.
+- relative `env_dir` resolves from current working directory.
+- files with valid env-var names (`[A-Za-z_][A-Za-z0-9_]*`) are loaded.
+- values are loaded from file contents with trailing newline trimming.
+- existing process env vars are preserved.
+- invalid names and subdirectories are skipped.
+- missing/unreadable `env_dir` fails command execution.
+
+Guidance:
+
+- do not put secret values directly in YAML.
+- configure env var names in config and provide values via env/secrets files.
+
+## 10. Examples
+
+Maintained examples:
+
+- `examples/pipeline.minimal.yml`
+- `examples/pipeline.production.yml`
+- `examples/pipeline.full.annotated.yml`
+- `examples/campaigns/sample-campaign/campaign.yml`
+- `examples/campaigns/sample-campaign/speakers.yml`

+- `examples/campaigns/sample-campaign/glossary.yml`
+- `examples/campaigns/sample-campaign/session.template.yml`
+- `examples/session.local-audio.yml`
+- `examples/session.s3-audio.yml`
+
+These examples are validated by `internal/config` tests.

+# Development Guide
+
+## Purpose
+Canonical contributor workflow and engineering conventions for implemented Narratio behavior.
+
+## Repository layout
+
+- `cmd/narratio/`: CLI entrypoint.
+- `internal/app/`: command handlers, plan/run/resume orchestration, cleanup gates, secrets loading.
+- `internal/config/`: strict YAML loading, defaults, and validation.
+- `internal/stage/`: stage implementations and stage registry/order.
+- `internal/adapters/`: external boundary adapters (WhisperX, Seriatim, Audita, Scriptorium, storage, notify).
+- `internal/manifest/`: session/run manifest types and persistence.
+- `internal/artifacts/`: canonical local/remote path helpers and local artifact store.
+- `docs/`: canonical documentation set.
+- `examples/`: maintained config examples used by tests.
+
+## Build and test commands
+
+- Run focused CLI behavior checks:
+
+```bash
+go test ./internal/app -run TestExecute -v
+```
+
+- Run config example load/validate checks:
+
+```bash
+go test ./internal/config -run TestExamplesLoadAndValidate -v
+```
+
+- Run full test suite:
+
+```bash
+go test ./...
+```
+
+## Coding conventions
+
+- Keep orchestration explicit and stage-driven; do not introduce generic workflow/DAG abstractions.
+- Keep external-system details inside adapter packages; stages should consume Narratio-level contracts only.
+- Use centralized path helpers from `internal/artifacts` rather than ad hoc path concatenation.
+- Preserve manifest-driven state transitions (`running`, `succeeded`, `failed`, `skipped`, `stale`) as the source of run progress.
+- Keep user/operator docs implementation-accurate; planned work belongs only under `docs/roadmap/`.
+
+For design principles and invariants, see [docs/architecture.md](./architecture.md). For stage/adapter contracts, see [docs/internal/README.md](./internal/README.md).
+
+## Dependency policy
+
+- Prefer Go standard library where practical.
+- Add third-party dependencies only when they provide clear value for required behavior.
+- Keep dependency additions narrow to the boundary package that needs them.
+
+## Change playbooks
+
+### Add config fields
+
+1. Add fields to config structs in `internal/config`.
+2. Set defaults in `internal/config/defaults.go` when appropriate.
+3. Add validation rules in `internal/config/validate.go`.
+4. Add or update load/validate tests in `internal/config/*_test.go`.
+5. Update canonical config docs and examples:
+   - [docs/config.md](./config.md)
+   - relevant files under `examples/`
+
+### Add CLI flags or commands
+
+1. Update command parsing and behavior in `internal/app`.
+2. Add or update command tests (`TestExecute` and command-specific tests).
+3. Update [docs/cli.md](./cli.md) and, if operator workflow changes, [docs/operations.md](./operations.md).
+
+Remote-storage commands must obtain object storage through the app-level command object-store helper. Do not call `storage.NewObjectStoreFromConfig` directly from command handlers; the helper loads configured filesystem secrets before constructing the storage adapter.
+
+### Add or modify stages/adapters
+
+1. Implement stage behavior in `internal/stage` with clear input/output boundaries.
+2. Keep external transport/subprocess details in `internal/adapters`.
+3. Preserve manifest and promotion semantics expected by runner and archive logic.
+4. Add/update stage and adapter tests.
+5. Update internal component contracts in `docs/internal/`.
+
+### Update examples
+
+1. Keep canonical examples only in `examples/`.
+2. Ensure examples load and validate through runtime config paths.
+3. Update `internal/config/load_validate_test.go` as needed.
+4. Update links in `docs/config.md` if example filenames change.
+
+### Update docs and roadmap
+
+1. Keep implemented behavior in canonical docs (`README`, `docs/*.md`, `docs/internal/`).
+2. Keep planned/unimplemented behavior only in `docs/roadmap/`.
+3. After completing roadmap items, remove or mark them complete in `docs/roadmap/documentation.md`.
+4. Run a link/path sweep before finalizing changes.

+# Go Project Documentation Policy
+
+## Purpose
+
+Project documentation must help four audiences:
+
+1. users who need to run the application;
+2. administrators/operators who need to configure and operate it;
+3. developers who need to understand and change it safely;
+4. LLM coding agents that need clear scope, boundaries, and invariants.
+
+Docs should be accurate, concise, task-oriented, and organized by audience. Prefer links to canonical docs over repetition.
+
+## Core Rules
+
+### 1. Keep docs concise
+
+Each document should cover a defined scope and only the essentials for that scope.
+
+Avoid:
+- long background explanations;
+- repeated reference material;
+- implementation detail in user-facing docs;
+- aspirational language outside roadmap docs;
+- verbose examples where one minimal example is clearer.
+
+### 2. Document only implemented behavior outside roadmap files
+
+Unimplemented, planned, aspirational, experimental, or future work may be described only under:
+
+- `docs/roadmap/`
+
+No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
+
+If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
+
+### 3. Use canonical homes
+
+Each type of information should have one canonical location.
+
+Canonical homes:
+
+- project purpose and quickstart: `README.md`
+- development principles: `docs/architecture.md`
+- configuration reference: `docs/config.md`
+- CLI reference: `docs/cli.md`
+- operations and recovery: `docs/operations.md`
+- troubleshooting: `docs/troubleshooting.md`
+- implemented internals: `docs/internal/`
+- future work: `docs/roadmap/`
+- contributor workflow: `docs/development.md`
+- copyable examples: `examples/`
+
+Other files should summarize briefly and link to the canonical source.
+
+### 4. Keep examples real
+
+Examples should be valid, maintained, and free of secrets.
+
+Where practical:
+- example configs should load successfully;
+- example commands should match real CLI syntax;
+- important examples should be covered by tests.
+
+## Documentation Profiles
+
+All projects require:
+
+- `README.md`
+- `docs/architecture.md`
+
+Additional docs depend on the project.
+
+### Small library
+
+Recommended:
+- `docs/development.md`, if contributor conventions are non-obvious
+
+### Simple CLI
+
+Required:
+- `docs/cli.md`
+
+Recommended:
+- `docs/development.md`
+
+### Config-driven CLI
+
+Required:
+- `docs/cli.md`
+- `docs/config.md`
+
+Recommended:
+- `examples/`
+- `docs/development.md`
+
+### Stateful or operator-facing application
+
+Required:
+- `docs/cli.md`, if CLI-based
+- `docs/config.md`, if config-driven
+- `docs/operations.md`
+
+Recommended:
+- `docs/troubleshooting.md`
+- `examples/`
+- `docs/development.md`
+
+### Modular, staged, service-oriented, or orchestration application
+
+Required:
+- `docs/cli.md`, if CLI-based
+- `docs/config.md`, if config-driven
+- `docs/operations.md`
+- `docs/internal/`
+- `docs/development.md`
+
+Recommended:
+- `docs/troubleshooting.md`
+- validated examples under `examples/`
+
+## Required Documents
+
+### README.md
+
+**Audience:** users, administrators, operators
+
+The README is the outward-facing project orientation page.
+
+It should include, in order:
+
+1. concise description;
+2. elevator pitch;
+3. shortest useful command or usage example;
+4. links to targeted docs.
+
+The README should be short. It is not a manual.
+
+The “shortest useful command” means the simplest command that performs the project’s core use case. (It does not mean `app --help`.)
+
+### docs/architecture.md
+
+**Audience:** developers, LLM coding agents
+
+`docs/architecture.md` is required for every project.
+
+It is an inward-facing development policy document. It should describe how the project is intended to be built and changed.
+
+It should include:
+
+- project shape;
+- core design principles;
+- package and boundary philosophy;
+- state/persistence philosophy, if applicable;
+- external integration philosophy, if applicable;
+- error-handling and logging principles;
+- testing expectations;
+- documentation expectations;
+- architectural invariants;
+- explicit non-goals, if useful.
+
+For small projects, this file may be brief. It may simply state that the project is intentionally narrow, monolithic, and dependency-light.
+
+### docs/config.md
+
+**Audience:** administrators, operators, advanced users
+
+Required for applications with configuration files.
+
+It should include, in order:
+
+1. config file locations and discovery precedence;
+2. minimal working config;
+3. production-oriented config;
+4. full configuration reference;
+5. secrets handling, if applicable;
+6. links to maintained examples.
+

+- cleanup behavior;
+- archive/backup behavior;
+- safe recovery procedures;
+- operational caveats.
+
+### docs/troubleshooting.md
+
+**Audience:** administrators, operators

+- diagnostic command or inspection step;
+- safe fix;
+- relevant links.
+
+### docs/development.md
+
+**Audience:** developers, LLM coding agents
+
+Required for projects maintained by humans and LLM coding agents.

+- how to add stages/modules/adapters, if applicable;
+- how to update examples;
+- documentation update expectations.
+
+### docs/internal/
+
+**Audience:** developers, LLM coding agents
+
+Required for modular, staged, service-oriented, or orchestration projects.
+
+This directory describes implemented internal components. It is not the roadmap.
+
+Use one file per major component where useful.
+
+Each component doc should include:
+
+1. purpose;
+2. inputs and outputs;
+3. boundaries;

+
+Roadmap docs should clearly distinguish:
+
+- proposed work;
+- accepted plans;
+- deferred ideas;
+- rejected ideas;
+- implementation prompts or task breakdowns, if useful.
+
+Roadmap docs should not be confused with current behavior.
+
+### docs/integrations/
+
+**Audience:** developers, LLM coding agents
+
+Required for projects that depend on external CLIs, APIs, services, protocols, or file formats where the integration contract is important to maintain.
+
+This directory contains concise, versioned reference notes for external integration contracts. It should document only the parts of the external system that this project actually uses.
+
+Use one file per integration where useful.
+
+## Examples Directory
+
+Projects with non-trivial configuration or workflows should include `examples/`.
+
+Useful examples include:
+
+- minimal working config;
+- production-oriented config;
+- full annotated config;
+- local development config;
+- remote/object-storage config;
+- minimal session/input file.
+
+Examples should be valid, maintained, tested when practical, and linked from relevant docs.
+
+## Security and Privacy
+
+Docs and examples must not include:
+
+- real API keys;
+- tokens;
+- passwords;
+- private keys;
+- private environment dumps;
+- sensitive user data;
+- raw private transcripts;
+- private infrastructure details unless intentionally public.
+
+Document secret-handling mechanisms, not actual secret values.
+
+## Maintenance Rules
+
+When docs change, verify the affected behavior.
+
+Where practical:
+
+- load example config files in tests;
+- test CLI examples or command parser behavior;
+- validate documented flags against real flags;
+- remove stale references;
+- update links after renames;
+- keep roadmap content out of non-roadmap docs.
+
+If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
+
+Documentation is complete only when it matches the current code.
+
+## Documentation Change Checklist
+
+Before merging documentation changes, verify:
+
+- README is concise and orientation-focused.
+- `docs/architecture.md` describes development principles.
+- Future work appears only under `docs/roadmap/`.
+- User-facing docs avoid unnecessary internals.
+- Developer-facing docs preserve boundaries and invariants.
+- Config examples match the schema.
+- CLI examples match real commands and flags.
+- Defaults appear in the canonical config reference.
+- No secrets or private data are included.
+- Links are accurate.

-# Audita Subprocess Operations
+# Integration: audita
 
-This document describes how parent processes should invoke `audita process` safely in production orchestration.
+## Purpose
+Define Narratio's adapter contract for transcript polishing via Audita CLI subprocess execution.
 
-## Recommended command form
+## Inputs and Outputs
+Inputs (`audita.PolishRequest`):
+- base transcript path
+- glossary path
+- output polished transcript path
+- optional report path (required when report enabled)
+- work dir
+- generated config path
+- stdout/stderr log paths
+- optional module/model/base URL and concurrency knobs
 
-Use explicit file outputs for orchestrated runs:
+Outputs (`audita.PolishResult`):
+- polished transcript path
+- optional report path
+- generated config path
+- stdout/stderr log paths
+- exit code, duration, invoked binary
+- adapter metadata
 
-```sh
+## Boundaries
-audita process <transcript.json> \
+Owns:
-  --transcript-description "Brief context that may help resolve ambiguous terms." \
+- Deterministic CLI argument construction for `audita process`
-  --glossary <glossary.yaml> \
+- Environment bridging for API credentials
-  --output <output-transcript.json> \
+- Invocation config emission
-  --report-json <report.json>
+- Output validation for polished transcript and report
-```
 
-Additional flags that may be situationally appropriate:
+Does not own:
-- `--config <path>` to select an explicit versioned config file.
+- Upstream/downstream stage orchestration
-- `--output-schema <bare-segments|audita-v1>` to select transcript output shape.
+- Credential sourcing policy beyond required env-var presence check
-- `--work-dir <dir>` to control diagnostics location.
-- `--work-dir-retention <always|auto|never>` to control retained run directories.
-- `--total-llm-concurrency`, `--proposal-llm-concurrency`, and `--validation-llm-concurrency` when orchestration needs to set explicit LLM throughput controls.
-- `--modules ...` only when intentionally overriding the default sequence.
 
-For config-driven orchestration, validate config files in CI/preflight:
+## Config Fields Used
+Via `pipeline.audita.*` mapped in app/stage wiring:
+- `binary`, `timeout`, `llm_api_key_env`, `modules`, `base_url`, `model`
+- `transcript_description`, `config_path`, `output_schema`, `work_dir_retention`
+- `total_llm_concurrency`, `proposal_llm_concurrency`, `validation_model`, `validation_llm_concurrency`, `report`
 
-```sh
+## External Adapters Used
-audita config validate --config <path>
+- Shared subprocess helper (`internal/adapters/subprocess`) to run CLI and capture logs.
-```
 
-## Stdout behavior
+## State and Manifest Behavior
+- No direct manifest writes.
+- Stage-level metadata records adapter provenance and credential-present signal.
+- Generated invocation YAML is written when `GeneratedConfigPath` is provided.
 
-- With `--output`: stdout is expected to be empty on success.
+## Skip and Resume Behavior
-- Without `--output`: stdout contains transcript JSON only on success.
+- Adapter has no skip/resume logic. Stage/runner controls this.
-- Report JSON is never written to stdout.
 
-## Stderr behavior
+## Failure Behavior
+- Constructor validation fails on invalid binary/timeout/schema/concurrency/URL values.
+- Run fails on missing required paths, missing required credential env var, subprocess errors, invalid polished JSON shape, or invalid report JSON.
+- Failures preserve stdout/stderr paths in returned result metadata.
 
-- Success path should be quiet or minimal human-readable logs.
+## Tests to Inspect Before Changing
-- Failure path writes concise human-readable errors.
+- `internal/adapters/audita/subprocess_test.go`
-- When a diagnostics run directory exists, failure stderr includes its path.
+- `internal/adapters/audita/fake_test.go`
-- Prompt/response diagnostic payloads are not streamed to stderr.
+- `internal/stage/polish_test.go`
 
-## Output file behavior
+## Architectural Invariants
-
+- Polished output must be valid JSON with top-level `segments` array.
-- `--output` writes transcript JSON in the selected output schema to the provided path.
+- When report is enabled, report output must be valid JSON.
-- Output write failures return nonzero and surface actionable errors.
+- If `llm_api_key_env` is configured, credential must be present in environment.
-- The command does not silently ignore output write errors.
-
-## Report JSON behavior
-
-- `--report-json` writes a machine-readable process report to the requested path.
-- Run-directory `report.json` is written independently under diagnostics.
-- Best-effort failure reports are emitted when possible without masking the primary failure.
-- Report write failures return nonzero with clear stderr messaging.
-- Report diagnostics metadata references run-directory artifacts including utilization diagnostics and correction ledger paths when available.
-
-## Diagnostics directory behavior
-
-- Each run creates (when possible) a per-run diagnostics directory.
-- Typical artifacts include transcript, normalization, chunking, invocation, effective config, LLM diagnostics, `utilization-diagnostics.json`, `correction-ledger.json`, `report.json`, and `error.log` on failure.
-- Failed runs retain diagnostics.
-- Under `auto` retention, successful runs with skipped/rejected corrections are retained; clean successful runs may be removed.
-
-## Exit codes
-
-- `0`: success.
-- Nonzero: failure (input/schema/config/module/LLM/runtime/output/report/diagnostics errors).
-
-Treat any nonzero as a failed subprocess invocation.
-
-## Timeout and cancellation
-
-- Runtime operations propagate context cancellation and request timeouts through LLM/scheduler paths.
-- On cancellation or timeout, the process exits nonzero and should not hang.
-- If diagnostics were initialized before failure, failure artifacts remain available for debugging.
-
-## Secret redaction expectations
-
-API keys and configured secret values are redacted from:
-- reports (`--report-json` and run-dir `report.json`);
-- diagnostics artifacts (including effective config and LLM interaction artifacts);
-- surfaced adapter/runtime errors;
-- test fixtures and regression outputs.
-
-Parent-process logs should still avoid printing raw environment variables.
-
-## Parent-process pipe guidance
-
-To avoid deadlocks in orchestrators:
-- always read both stdout and stderr concurrently when invoking as a subprocess;
-- prefer file outputs (`--output`, `--report-json`) for machine workflows;
-- treat stderr as human-readable diagnostics, not structured data;
-- parse structured results from output/report files.
-
-For Go callers, prefer `exec.CommandContext` with explicit timeout/cancellation and buffered/streamed readers for both pipes.

-# Narratio -> Scriptorium CLI Integration
+# Integration: scriptorium
-
+
-## 1. Purpose
+## Purpose
-
+Define Narratio's adapter contract for Scriptorium artifact generation and render-debug subprocess invocations.
-This document defines how Narratio should invoke Scriptorium through the **public CLI**.
+
-
+## Inputs and Outputs
-This is a **subprocess integration contract**, not an internal Go API contract.
+Inputs:
-
+- `RunArtifactRequest`: binary, config path, prompt/profile IDs, input map, vars map, timeout, output path, logs/config paths, optional API env and working dir
-## 2. Assumptions
+- `RenderArtifactRequest`: same core fields for render mode
-
+
-- `scriptorium` is installed and available on `PATH`.
+Outputs (`ArtifactResult`):
-- Scriptorium is configured with `config.yml`.
+- output path
-- `config.yml` provides `prompt_dir`, `profile_dir`, and `schema_dir` as needed.
+- stdout/stderr log paths
-- Prompt and profile libraries are already deployed for the environment.
+- generated config path
-- Narratio provides prepared artifact files (for example polished transcript, glossary, previous recap, campaign notes).
+- exit code and duration
-- Initial integration is synchronous subprocess execution.
+- command mode (`run` or `render`)
-- Narratio remains the orchestrator.
+- prompt/profile provenance
-
+- validation failure signal
-In normal operation, Narratio does not need to pass `--prompt-dir` and `--profile-dir` if they are supplied by Scriptorium config.
+- adapter metadata
-
+
-Narratio may pass `--config <PATH>` when it must use a non-default Scriptorium config file.
+## Boundaries
-
+Owns:
-## 3. Core Commands Narratio May Call
+- Deterministic CLI arg construction for `scriptorium run` and `scriptorium render`
-
+- Common request validation
-Primary commands for subprocess integration:
+- Invocation config emission
-
+- Output existence/non-empty checks
-- `scriptorium run`
+- Validation-failure mapping for run exit code 2
-- `scriptorium render`
+
-
+Does not own:
-For production generation, use `scriptorium run`.
+- Artifact selection policy (`analyze` stage)
-
+- Bounds semantic validation (`trim` stage)
-`scriptorium render` is for debugging, dry-runs, test assertions, and validating command construction without LLM execution.
+
-
+## Config Fields Used
-Note: `scriptorium serve` and HTTP API exist, but they are not the initial integration path.
+Via `pipeline.scriptorium.*` and stage-level artifact config:
-
+- `binary`, `config_path`, `timeout`, `render_debug`
-## 4. Command Selection Guidance
+- artifact-level `prompt_id`, `profile_id`, `timeout`, `inputs`, `vars`, `output_path`
-
+
-- Use `run` to generate an output artifact.
+## External Adapters Used
-- Use `render` to inspect the prepared prompt and effective settings without calling the LLM.
+- Shared subprocess helper (`internal/adapters/subprocess`).
-- Use `render --format json` when Narratio/tests need structured prepare output.
+
-
+## State and Manifest Behavior
-## 5. Recommended `run` Invocation Shape
+- No direct manifest writes.
-
+- Stage metadata records adapter outputs and command mode.
-Production shape:
+- Generated invocation YAML is written when requested.
-
+
-```bash
+## Skip and Resume Behavior
-scriptorium run \
+- Adapter has no skip/resume logic. Stage/runner controls execution.
-  --prompt <prompt_id> \
+
-  --input transcript=<processed-transcript-path> \
+## Failure Behavior
-  --out <output-artifact-path>
+- Request validation fails for missing binary/prompt/output, invalid timeout, invalid input/var names, or missing required API env var.
-```
+- Subprocess errors bubble with command context.
-
+- `run` exit code 2 is treated as `ValidationFailed=true` and surfaced as error by calling stage.
-Common optional additions:
+- Successful subprocess still fails if output file is missing/empty.
-
+
-- `--config <path>`: use a specific Scriptorium config file.
+## Tests to Inspect Before Changing
-- `--profile <profile_id>`: override prompt default profile.
+- `internal/adapters/scriptorium/subprocess_test.go`
-- `--var name=value` (repeatable): small metadata values.
+- `internal/adapters/scriptorium/fake_test.go`
-- `--input name=path` (repeatable): additional named artifacts.
+- `internal/stage/analyze_test.go`
-- `--timeout <duration>`: per-run timeout override.
+- `internal/stage/trim_test.go`
-- Runtime model override flags (`--llm-base-url`, `--model`, etc.) only for exceptional/operator-directed cases.
+
-
+## Architectural Invariants
-## 6. Recommended `render` Invocation Shape
+- Both modes require explicit timeout > 0.
-
+- Input/var maps are sorted into deterministic CLI argument order.
-Human-readable debug shape:
+- Run-mode validation failures are represented explicitly, not silently skipped.
-
-```bash
-scriptorium render \
-  --prompt <prompt_id> \
-  --input transcript=<processed-transcript-path> \
-  --format text
-```
-
-Structured debug/test shape:
-
-```bash
-scriptorium render \
-  --prompt <prompt_id> \
-  --input transcript=<processed-transcript-path> \
-  --format json \
-  --out <render-debug-path>
-```
-
-`render` does **not** call the LLM, does **not** validate model output, and does **not** perform repair.
-
-## 7. Inputs
-
-- Pass inputs as repeated `--input name=path` flags.
-- `name` must match the Prompt Definition input name.
-- Prefer absolute paths, or paths relative to a working directory controlled by Narratio.
-- Pass Audita output as the primary transcript input.
-- Additional inputs may include glossary, previous recap, campaign notes, event logs, final state maps, or other prompt-specific artifacts.
-- Scriptorium reads input files directly; Narratio does not need to inline file content for CLI use.
-
-## 8. Variables
-
-Use repeated `--var name=value` for small metadata values.
-
-Typical examples:
-
-- `session_date`
-- `session_id`
-- `campaign_name`
-- `previous_session_id`
-- `output_kind`
-
-Large content belongs in input files, not `--var` values.
-
-## 9. Prompt IDs and Output Artifact Types
-
-Narratio should treat prompt IDs as configuration, not hardcoded business logic.
-
-Narratio config may map stage/output names to prompt IDs, for example:
-
-- session recap prompt
-- structured event extraction prompt
-- glossary suggestion prompt
-- player-facing summary prompt
-
-Prompt IDs used by Narratio should come from the deployed Scriptorium prompt library.
-
-## 10. Profiles
-
-- Prompts may declare `default_profile`.
-- Narratio may omit `--profile` to use prompt default profile.
-- Narratio may pass `--profile` to force profile selection.
-- This enables environment/profile selection like `local-fast`, `local-quality`, `frontier`, `batch`, or test profiles.
-- Profile names should generally be Narratio configuration values.
-
-## 11. Runtime Overrides
-
-Supported runtime override flags:
-
-- `--llm-base-url`
-- `--model`
-- `--api-key-env`
-- `--temperature`
-- `--max-tokens`
-- `--top-p`
-- `--timeout`
-
-Guidance:
-
-- Keep normal model/runtime settings in Execution Profiles.
-- Use runtime overrides only for explicit per-run exceptions, tests, or operator overrides.
-- Never pass raw API keys on the command line.
-- `--api-key-env` names an environment variable; Narratio must ensure that variable is set in subprocess environment.
-
-## 12. Config Behavior
-
-- Default config path: `/etc/scriptorium/config.yml`.
-- `--config <PATH>` overrides default path.
-- Missing default config is allowed by Scriptorium.
-- If `--config` is provided explicitly, the file must exist and be valid.
-- CLI flags override `config.yml`.
-- `config.yml` overrides built-in application defaults.
-
-Narratio can either:
-
-- rely on system default config path, or
-- carry an explicit config path and pass `--config`.
-
-## 13. Environment Handling
-
-Subprocess environment recommendations:
-
-- Pass through required API-key environment variables referenced by `api_key_env`.
-- Do not pass raw API keys as CLI arguments.
-- Avoid logging full environment dumps.
-- Capture stdout and stderr separately.
-- Use a controlled working directory.
-- Prefer absolute artifact paths.
-
-## 14. Output Handling
-
-For `scriptorium run`:
-
-- Use `--out` when Narratio needs durable artifact files.
-- Without `--out`, artifact content is written to stdout.
-- Preferred orchestration pattern: always use `--out`, then treat the file as stage output artifact.
-- Capture stderr for diagnostics.
-
-For `scriptorium render`:
-
-- Use `--out` to store render diagnostics.
-- Use `--format json` when tests need to inspect selected profile, effective runtime settings, input hashes, prompt hash, and rendered messages.
-
-## 15. Exit Status and Errors
-
-Current CLI behavior (verified from implementation/tests):
-
-- `0`: success.
-- `1`: runtime/parse/config/load/render/generation/IO error.
-- `2`: run completed but output validation failed (`ValidationFailed`).
-
-Additional details:
-
-- On `run`, output artifact write happens before exit code selection. If validation fails, artifact may still be written and exit code is `2`.
-- `stderr` carries both errors and normal run summary output; non-empty stderr alone does not imply failure.
-- `render` returns `0` on success and `1` on failures.
-
-Narratio should treat non-zero exit codes as failed stage execution, but may record generated artifact paths if a run exited `2` and output file exists.
-
-## 16. Recommended Narratio Integration Pattern
-
-1. Build CLI args from Narratio stage configuration.
-2. Use subprocess context cancellation/timeout.
-3. Pass absolute input paths.
-4. Pass `--out` to a session-scoped artifact path.
-5. Add `--var` metadata values.
-6. Optionally add `--config`.
-7. Optionally add `--profile`.
-8. Ensure required API-key env vars are present.
-9. Run subprocess synchronously.
-10. Capture stdout/stderr separately.
-11. On success, store output artifact path and invocation metadata in stage artifacts.
-12. On failure, store exit code and stderr diagnostics in stage status.
-
-## 17. Suggested Narratio Configuration Shape
-
-Illustrative `pipeline.yml` shape:
-
-```yaml
-scriptorium:
-  binary: scriptorium
-  config_path: /etc/scriptorium/config.yml
-  timeout: 10m
-  render_debug: false
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: dnd.session_recap
-      profile_id: local-quality   # optional
-      output_path: artifacts/session_recap.md
-      timeout: 10m
-      render_debug: false          # optional artifact override
-      inputs:
-        transcript:
-          source: trimmed_transcript
-          required: true
-        previous_recap:
-          source: previous_session_artifact
-          artifact: session_recap
-          path: ""                 # optional
-          required: false
-      vars:
-        session_id: true
-        session_date: true
-        campaign_name: true
-        previous_session_id: true
-        output_kind: session_recap
-```
-
-The key idea: map Narratio artifact names to prompt ID, optional profile, expected inputs, vars, and output destination.
-
-## 18. Testing Strategy for Narratio Integration
-
-- Use `scriptorium render --format json` to verify command construction without LLM calls.
-- Use dedicated test prompt/profile libraries for integration tests.
-- Use small fixture transcripts.
-- Verify missing-input failure behavior.
-- Verify prompt `default_profile` behavior.
-- Verify explicit `--profile` override behavior.
-- Verify `--config` behavior (default and explicit).
-- Verify output file creation when `--out` is used.
-- Verify stderr capture on failures.
-- Avoid real API keys in tests.
-
-## 19. Security and Privacy Notes
-
-- Never pass raw API keys on command line.
-- Do not log full rendered prompts by default; transcripts may contain sensitive content.
-- Avoid logging prompt content unless explicit debug mode is enabled.
-- Treat generated artifacts as potentially sensitive.
-- Use session-scoped, access-controlled output paths.
-- `api_key_env` names should come from environment management, not embedded secrets.
-
-## 20. Initial D&D Artifact Generation Examples
-
-These are examples only. Use prompt IDs from the deployed prompt library.
-
-Session recap:
-
-```bash
-scriptorium run \
-  --prompt dnd.session_recap \
-  --input transcript=/work/session-42/transcript.polished.md \
-  --input glossary=/work/session-42/glossary.yml \
-  --out /work/session-42/artifacts/session_recap.md
-```
-
-Structured events:
-
-```bash
-scriptorium run \
-  --prompt dnd.structured_events \
-  --input transcript=/work/session-42/transcript.polished.md \
-  --out /work/session-42/artifacts/structured_events.json
-```
-
-Glossary suggestions:
-
-```bash
-scriptorium run \
-  --prompt dnd.glossary_suggestions \
-  --input transcript=/work/session-42/transcript.polished.md \
-  --input previous_recap=/work/session-41/artifacts/session_recap.md \
-  --out /work/session-42/artifacts/glossary_suggestions.md
-```
-
-Player-facing summary:
-
-```bash
-scriptorium run \
-  --prompt dnd.player_summary \
-  --input transcript=/work/session-42/transcript.polished.md \
-  --input structured_events=/work/session-42/artifacts/structured_events.json \
-  --out /work/session-42/artifacts/player_summary.md
-```
-
-## 21. Non-Goals
-
-Initial Narratio integration should not:
-
-- call Scriptorium internal Go packages
-- use HTTP API as the primary path
-- expect Scriptorium to read S3 refs directly
-- make Scriptorium responsible for Narratio stage state
-- make Scriptorium responsible for notification
-- require Scriptorium to understand D&D workflow semantics beyond prompt definitions
-
-## 22. Future Extension Notes
-
-Possible later extensions:
-
-- HTTP API integration
-- S3 artifact references if Scriptorium adds S3 reader support
-- richer render diagnostics and policy controls
-- token budgeting/prompt-size checks
-- batch execution if Scriptorium later adds batch support

-`seriatim` merges per-speaker WhisperX-style JSON transcripts into a single JSON transcript that preserves speaker identity and chronological order.
+## Purpose
-
+Define Narratio's adapter contract for merge, normalize, and trim subprocess invocations of Seriatim.
-The current implementation supports the `merge` command. It reads one or more input JSON files, optionally maps each input file to a canonical speaker using `speakers.yml`, sorts all segments by timestamp, detects and resolves overlaps when word-level timing is available, assigns consecutive numeric `id` values, and writes a merged JSON artifact.

-
-## Input JSON Format
-
-Each input file must be valid JSON with a top-level `segments` array. The current parser accepts the WhisperX segment subset needed for merging:
-
-```json
-{
-  "segments": [
-    {
-      "start": 1.25,
-      "end": 3.5,
-      "text": "Hello there.",
-      "words": [
-        {"word": "Hello", "start": 1.25, "end": 1.55, "score": 0.98},
-        {"word": "there.", "start": 1.7, "end": 2.0}
-      ]
-    }
-  ]
-}
-```
-
-Required segment fields:
-
-- `start`: number, must be `>= 0`.
-- `end`: number, must be `>= start`.
-- `text`: string.
-
-Optional word fields:
-
-- `words`: array of word timing objects.
-- `words[].word`: string.
-- `words[].start`: optional number, must be `>= 0` when present.
-- `words[].end`: optional number, must be `>= start` when present with `start`.
-- `words[].score`: optional number.
-- `words[].speaker`: optional raw speaker label string.
-
-Word-level timing is preserved internally for overlap resolution. If a word is missing `start` or `end`, seriatim keeps the word text, emits a warning in the optional report, and does not use that word as a timing anchor. Word timing is not emitted in the final JSON artifact.
-
-## Speaker Map Format
-
-`speakers.yml` maps input files to canonical speaker names using ordered substring rules:
-
-This file is optional. If `--speakers` is omitted, `seriatim` uses each input file basename as the segment speaker label.
-
-```yaml
-match:
-  - speaker: "Eric Rakestraw"
-    match:
-      - "Eric_Rakestraw"
-      - "Eric"
-
-  - speaker: "Mike Brown"
-    match:
-      - "Mike_Brown"
-      - "mb"
-```
-
-For each `--input-file`, `seriatim` takes the file basename and evaluates the rules in order. The first rule with a matching substring wins, and no later rules are evaluated.
-
-For example, this input:
-
-```text
-samples/raw/2026-04-19-Eric_Rakestraw.json
-```
-
-matches this rule because the basename contains `Eric_Rakestraw`:
-
-```yaml
-- speaker: "Eric Rakestraw"
-  match:
-    - "Eric_Rakestraw"
-```
-
-Important details:
-
-- Matching is against the input file basename, not the full path.
-- Matching is case-insensitive.
-- Rules are evaluated from first to last.
-- Each rule must have a non-empty `speaker`.
-- Each rule must have at least one non-empty `match` string.
-- Duplicate speaker names are invalid.
-- Every input file must match at least one rule or the command fails.
-
-Deprecated old format:
-
-```yaml
-inputs:
-  eric.json:
-    speaker: "Eric Rakestraw"
-```
-
-The old `inputs:` direct mapping format is no longer supported.
-
-## Output JSON Format
-
-`--output-modules json` controls the writer. `--output-schema` controls the JSON contract that writer serializes.
-
-The named schemas are stable public contracts. If a consumer depends on a specific shape, it should request that schema explicitly at runtime. The runtime default selection may change in a future release.
-
-The `seriatim-intermediate` schema is the current default selection when neither `--output-schema` nor `SERIATIM_OUTPUT_SCHEMA` is set. It stays close to the minimal schema, but adds optional `categories` on each segment:
-
-```json
-{
-  "metadata": {
-    "application": "seriatim",
-    "version": "dev",
-    "output_schema": "seriatim-intermediate"
-  },
-  "segments": [
-    {
-      "id": 1,
-      "start": 1.25,
-      "end": 3.5,
-      "speaker": "Eric Rakestraw",
-      "text": "Hello there.",
-      "categories": ["backchannel"]
-    }
-  ]
-}
-```
-
-The `seriatim-full` schema uses the full seriatim envelope:
-
-```json
-{
-  "metadata": {
-    "application": "seriatim",
-    "version": "dev",
-    "input_reader": "json-files",
-    "input_files": ["eric.json", "mike.json"],
-    "preprocessing_modules": ["validate-raw", "normalize-speakers", "trim-text"],
-    "postprocessing_modules": ["detect-overlaps", "resolve-overlaps", "backchannel", "filler", "resolve-danglers", "coalesce", "detect-overlaps", "autocorrect", "assign-ids", "validate-output"],
-    "output_modules": ["json"]
-  },
-  "segments": [
-    {
-      "id": 1,
-      "source": "eric.json",
-      "source_segment_index": 0,
-      "speaker": "Eric Rakestraw",
-      "start": 1.25,
-      "end": 3.5,
-      "text": "Hello there.",
-      "overlap_group_id": 1
-    },
-    {
-      "id": 2,
-      "source": "eric.json",
-      "source_ref": "word-run:1:1:1",
-      "derived_from": ["eric.json#0"],
-      "speaker": "Eric Rakestraw",
-      "start": 2.0,
-      "end": 2.5,
-      "text": "Resolved word run",
-      "categories": ["backchannel"]
-    }
-  ],
-  "overlap_groups": [
-    {
-      "id": 1,
-      "start": 1.25,
-      "end": 4.0,
-      "segments": ["eric.json#0", "mike.json#0"],
-      "speakers": ["Eric Rakestraw", "Mike Brown"],
-      "class": "unknown",
-      "resolution": "unresolved"
-    }
-  ]
-}
-```
-
-The `seriatim-minimal` schema emits minimal metadata and compact ordered segments:
-
-```json
-{
-  "metadata": {
-    "application": "seriatim",
-    "version": "dev",
-    "output_schema": "seriatim-minimal"
-  },
-  "segments": [
-    {
-      "id": 1,
-      "start": 1.25,
-      "end": 3.5,
-      "speaker": "Eric Rakestraw",
-      "text": "Hello there."
-    }
-  ]
-}
-```
-
-Minimal output intentionally omits categories, overlap groups, source/provenance fields, and pipeline configuration metadata.
-
-Intermediate output intentionally omits overlap groups and source/provenance fields, but keeps optional `categories` and minimal metadata.
-
-Segments are sorted deterministically by:
-
-```text
-(start, end, source, source_segment_index/source_ref, speaker)
-```
-
-Final segment IDs are assigned after sorting and start at `1`.
-
-The public Go output contract is available from:
-
-```go
-import "gitea.maximumdirect.net/eric/seriatim/schema"
-```
-
-The same package embeds machine-readable JSON Schemas in `schema/full-output.schema.json`, `schema/intermediate-output.schema.json`, and `schema/minimal-output.schema.json`. The default `validate-output` postprocessor validates the selected output shape and verifies final segment IDs are present, sequential, and start at `1`.
-
-## Overlap Detection
-
-The default postprocessing pipeline detects overlapping segment groups.
-
-Overlap behavior:
-
-- A strict timing overlap is required: `next.start < current_group_end`.
-- Segments that only touch at a boundary are not grouped.
-- Groups require at least two distinct speakers.
-- Transitive overlaps are grouped together.
-- Segments in detected groups receive `overlap_group_id`.
-- `overlap_groups[].segments` contains stable references in `source#source_segment_index` format.
-- `class` is currently `unknown`.
-- `resolution` is `unresolved` until `resolve-overlaps` replaces the group.
-
-## Overlap Resolution
-
-The default postprocessing pipeline runs `detect-overlaps`, then `resolve-overlaps`, then `backchannel`, then `filler`, then `resolve-danglers`, then `coalesce`, then a second `detect-overlaps` pass.
-
-For each detected overlap group, `resolve-overlaps` uses preserved WhisperX word timing to build smaller word-run replacement segments:
-
-- The resolution window expands the detected overlap group by `--coalesce-gap` seconds on both sides.
-- Nearby same-speaker context segments are included when they intersect the expanded window and their start or end is within `--coalesce-gap` of the original overlap boundary.
-- Once a segment is selected for replacement, all timed words from that segment participate in word-run construction; the window controls segment selection, not per-word clipping.
-- Context segments that are part of another detected overlap group are not pulled into the current group.
-- Untimed words are included in replacement text in original word order when nearby timed words create a replacement run.
-- Untimed words do not affect replacement segment start/end times or word-run gap splitting.
-- Words for the same speaker are merged into one run when the gap between adjacent words is no greater than `SERIATIM_OVERLAP_WORD_RUN_GAP`.
-- The default word-run gap is `1.0` seconds.
-- Set `SERIATIM_OVERLAP_WORD_RUN_GAP` to a positive number of seconds to override the default.
-- Near-start replacement word runs are reordered so shorter segments come first when adjacent starts are within `SERIATIM_OVERLAP_WORD_RUN_REORDER_WINDOW`.
-- The default word-run reorder window is `1.0` seconds.
-- Set `SERIATIM_OVERLAP_WORD_RUN_REORDER_WINDOW` to a positive number of seconds to override the default.
-- Replacement segment text is built by joining word text with single spaces.
-- Replacement segments include `source_ref` and `derived_from`.
-- Replacement segments omit `source_segment_index` because they are derived from one or more original segments.
-- Resolved overlap groups are removed before the second detection pass.
-- Replacement segments are left without `overlap_group_id` until the second detection pass annotates any remaining overlap.
-- If a speaker has no usable word timing in a group, that speaker's original segment is kept.
-- If no speakers in a group have usable word timing, the original group and annotations remain unchanged.
-
-## Backchannels
-
-The default pipeline runs `backchannel` before `coalesce`. It tags short acknowledgement segments with:
-
-```json
-"categories": ["backchannel"]
-```
-
-Backchannel matching is case-insensitive, ignores punctuation for matching and word-count purposes, trims surrounding whitespace, and requires a matching acknowledgement phrase, no more than three whitespace-delimited words, and duration no greater than `SERIATIM_BACKCHANNEL_MAX_DURATION` seconds. The default maximum duration is `2.0` seconds.
-
-## Fillers
-
-The default pipeline runs `filler` after `backchannel` and before `coalesce`. It tags short filler utterances with:
-
-```json
-"categories": ["filler"]
-```
-
-Filler matching is case-insensitive, ignores punctuation for matching and word-count purposes, trims surrounding whitespace, and requires only filler tokens such as `um`, `uh`, `er`, `erm`, `ah`, `eh`, `hmm`, `mm`, or repeated combinations of those tokens. Matching segments must contain no more than three whitespace-delimited words and have duration no greater than `SERIATIM_FILLER_MAX_DURATION` seconds. The default maximum duration is `1.25` seconds.
-
-## Dangler Resolution
-
-The default pipeline runs `resolve-danglers` before `coalesce` and before the second overlap detection pass. It repairs short derived fragments when they share provenance with a nearby segment:
-
-- Dangling-end fragments have no more than two words and end in punctuation.
-- Dangling-start fragments have no more than two words.
-- Matching uses same-speaker segments with any shared `derived_from` value.
-- Merged segments use `source_ref` values such as `resolve-danglers:1`, keep the target segment's transcript position, and union `derived_from`.
-
-## Coalescing
-
-The default pipeline runs `coalesce` after `resolve-danglers` and before the second overlap detection pass. It merges adjacent same-speaker segments in the transcript's current order when `next.start - current.end <= --coalesce-gap`.
-
-Coalesced segments use `source_ref` values such as `coalesce:1`, include `derived_from`, and omit `source_segment_index`.
-
-Different-speaker backchannel and filler segments do not block coalescing of surrounding same-speaker segments. Same-speaker backchannel and filler segments are merged normally when they are within `--coalesce-gap`. When same-speaker segments are coalesced, any `backchannel` or `filler` category from the merged inputs is dropped from the coalesced segment.
-
-## Autocorrect
-
-Autocorrect is included in the default postprocessing pipeline. If `--autocorrect` is omitted, the module leaves transcript text unchanged and records a skip event in the optional report.
-
-Enable corrections by passing `--autocorrect`:
-
-```sh
-go run ./cmd/seriatim merge \
-  --input-file input.json \
-  --autocorrect autocorrect.yml \
-  --output-file merged.json
-```
-
-`autocorrect.yml` format:
-
-```yaml
-autocorrect:
-  - target: "Hrank"
-    match:
-      - "hrank"
-      - "Frank"
-
-  - target: "Mike Brown"
-    match:
-      - "Mike Pat"
-```
-
-Matching behavior:
-
-- Matching is case-sensitive.
-- Matches apply only to whole tokens, not substrings inside larger words.
-- Punctuation and whitespace can surround a match.
-- Multi-word and hyphenated matches are supported.
-- Duplicate match strings are invalid, including duplicates across separate rules.
-
-## Current Limitations
-
-- Only JSON input is supported.
-- Overlap resolution depends on WhisperX word timing; groups without usable word timing remain unresolved.
-- Alternate output formats are not implemented yet.
-
-## Release Builds
-
-Local builds record version metadata as `dev`. Release builds should inject the release version with `ldflags`:
-
-```sh
-go build -ldflags "-X gitea.maximumdirect.net/eric/seriatim/internal/buildinfo.Version=v1.0.0" ./cmd/seriatim
-```

+# Internal: Adapters
+
+## Purpose
+Describe the external adapter boundaries used by Narratio stages and app orchestration, including default runtime wiring.
+
+## Inputs and outputs
+Inputs:
+- Stage requests passed through adapter interfaces (for example transcription, merge/normalize/trim, polish, artifact generation, object-store operations, notifications).
+- Resolved config values used to construct default adapters.
+
+Outputs:
+- Adapter-specific result structs (paths, metadata, status/attempt info, duration/exit details).
+- Adapter errors returned to stage/app orchestration.
+
+## Boundaries
+Owns:
+- Transport/process/SDK details at system boundaries (`HTTP`, subprocess CLI invocation, AWS SDK calls).
+- Request/response contracts in `internal/adapters/*` packages.
+
+Does not own:
+- Stage sequencing, skip/force/resume decisions.
+- Manifest transition logic.
+- Canonical workspace path policy.
+
+## Config fields used
+Default wiring and adapter calls consume:
+- `pipeline.whisperx.*`
+- `pipeline.seriatim.*`
+- `pipeline.audita.*`
+- `pipeline.scriptorium.*`
+- `pipeline.storage.*` and `pipeline.archive.*` (object-store construction/gating)
+- `pipeline.notification.*` (sender boundary exists; placeholder behavior today)
+
+## External adapters used
+Runtime env boundary fields (`internal/stage.Env`):
+- `whisperx.Client`
+- `seriatim.Runner`
+- `audita.Runner`
+- `scriptorium.Runner`
+- `storage.ObjectStore`
+- `notify.Sender`
+
+Current execution usage:
+- Actively used by implemented stages: `WhisperX`, `Seriatim`, `Audita`, `Scriptorium`, `ObjectStore`, `Notifier`.
+- Present but not used by implemented stage set: legacy `storage.Backend`.
+
+Default construction in app runner:
+- Auto-constructed when not injected: WhisperX HTTP client, Seriatim subprocess runner, Audita subprocess runner, Scriptorium subprocess runner, object store (only when needed), and `notify.NoopSender`.
+- Object-store construction goes through app command orchestration so configured filesystem secrets are loaded before the storage adapter is initialized.
+- Callers can inject test/fake implementations through `app.RunOptions.Env`.
+
+## State and manifest behavior
+- Adapters do not directly mutate session/run manifests.
+- Stages and runner own manifest writes and stage status transitions.
+- Adapter outputs are persisted indirectly through stage result mapping (outputs/logs/generated configs/metadata).
+
+## Skip and resume behavior
+- No adapter-level skip/resume semantics.
+- Skip/resume/force behavior is decided by app runner using manifest stage state.
+
+## Failure behavior
+- Adapter constructors validate config-derived values and fail early on invalid required inputs.
+- Adapter run-time failures are returned to stage code with boundary context and are recorded as stage failures by runner logic.
+- Subprocess adapters preserve stdout/stderr and generated-config paths to aid diagnosis.
+
+## Tests to inspect before changing
+- `internal/adapters/whisperx/http_test.go`
+- `internal/adapters/seriatim/subprocess_test.go`
+- `internal/adapters/audita/subprocess_test.go`
+- `internal/adapters/scriptorium/subprocess_test.go`
+- `internal/adapters/storage/*_test.go`
+- `internal/adapters/notify/fake_test.go`
+- `internal/app/runner_test.go`
+
+## Architectural invariants
+- Stage code depends on adapter interfaces, not transport-specific implementation types.
+- External SDK-specific types remain inside adapter implementations.
+- Default app wiring must remain deterministic and overrideable via injected env dependencies.

+# Internal: Artifacts
+
+## Purpose
+Define Narratio artifact identity, catalog, and source-resolution behavior for:
+- built-in session artifacts;
+- configured analyze artifacts;
+- canonical previous-session artifact sources.
+
+## Inputs and outputs
+Inputs:
+- configured input sources (`pipeline.scriptorium.artifacts.*.inputs.*.source`);
+- session paths and manifest inputs/outputs;
+- runtime catalog state.
+
+Outputs:
+- resolved artifact path + provenance (`ResolvedSessionArtifact`);
+- runtime catalog entries for built-ins and configured artifacts;
+- requirement sets for canonical previous-session inputs.
+- canonical S3 session, run, current, session config, session locks, audio, and promoted artifact keys.
+
+## Boundaries
+Owns:
+- built-in source registry and validation;
+- configured artifact catalog identity (`narratio.artifact.<name>`);
+- canonical previous-session source parsing and resolution;
+- previous-session requirement collection (`CollectPreviousArtifactRequirements`).
+
+Does not own:
+- prepare-stage remote hydration;
+- stage success/skip transitions;
+- archive upload orchestration.
+
+## Built-in IDs
+| Artifact ID | Canonical file | Producer stage | Output kind |
+| --- | --- | --- | --- |
+| `narratio.transcript.base` | `transcripts/base.json` | `merge` | `transcript_base` |
+| `narratio.transcript.polished` | `transcripts/polished.json` | `polish` | `transcript_polished` |
+| `narratio.transcript.final` | `transcripts/final.json` | `normalize` | `transcript_final` |
+| `narratio.transcript.final_trimmed` | `transcripts/final.trimmed.json` | `trim` | `transcript_final_trimmed` |
+| `narratio.bounds.session` | `artifacts/session_bounds.json` | `trim` | `session_bounds` |
+
+## Source families
+- built-in: `narratio.transcript.*`, `narratio.bounds.session`
+- configured artifact: `narratio.artifact.<artifact_key>`
+- canonical previous-session artifact: `narratio.previous_session.artifact.<artifact_key>`
+
+## S3 key helpers
+- session prefix: `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/`
+- session config: `{session_prefix}/session.yml`
+- session lock store: `{session_prefix}/locks.yml`
+- run prefix: `{session_prefix}/runs/{run_id}/`
+- audio prefix: `{session_prefix}/{session.inputs.audio_s3.prefix}`
+- current manifest: `{session_prefix}/current/manifest.json`
+- current run pointer: `{session_prefix}/current/run_id.txt`
+
+## Runtime catalog model
+Catalog entries track:
+- `planned`: source is registered for this run;
+- `executable`: configured artifact is selected for analyze execution;
+- `available`: usable local file exists (generated this run or reused from disk).
+
+Configured artifact provenance values include:
+- `generated.current_analyze_run`
+- `filesystem.disabled_artifact_output`
+
+Previous-session canonical provenance values include:
+- `manifest.inputs.previous_cache`
+- `current_session.previous_cache`
+
+## Resolution behavior
+- Built-ins resolve via manifest producer outputs first, then canonical fallback paths.
+- Configured `narratio.artifact.<name>` sources resolve through catalog availability.
+- Canonical previous-session sources resolve to current-session `previous/` cache candidates derived from configured artifact canonical output paths.
+- Archive-relative configured artifact paths under `artifacts/` are cached without a redundant nested `artifacts/` segment.
+- Previous-session canonical resolution prefers manifest-recorded input paths when present, then filesystem fallback under `previous/artifacts/**`.
+
+## Previous-session requirement scanning
+`CollectPreviousArtifactRequirements`:

+# Internal: Command Restore
+
+## Purpose
+Define the implemented `narratio session restore` contract: committed remote-state discovery, deterministic plan classification, safe file install semantics, and restore reporting.
+
+## Inputs and outputs
+Inputs:
+- CLI syntax: `narratio session restore <session_id>`.
+- CLI flags: `--config`, `--campaign`, `--campaign-file`, `--session`, `--previous-session-id`, `--dry-run`, `--force`, `--include-audio`.
+- Resolved/validated `pipeline.yml` and `session.yml`.
+- Configured remote object store.
+- Remote committed current-state markers (`current/run_id.txt`, `current/manifest.json`).
+
+Outputs:
+- Dry-run summary to stdout (plan + counts).
+- Non-dry-run completion summary to stdout.
+- Local durable session files restored under canonical session root.
+- Non-dry-run restore report at `reports/restore-latest.json`.
+
+## Boundaries
+Owns:
+- Restore command flag parsing and command wiring.
+- Remote current-state discovery and identity validation.
+- Restore plan construction and conflict classification.
+- Restore execution for planned downloads.
+- Restore report model and persistence.
+
+Does not own:
+- Stage execution orchestration (`run`, `resume`, `run-stage`).
+- Archive publish behavior (owned by archive stage).
+- Storage transport implementation details (owned by storage adapters).
+
+## Config fields used
+- Config/session discovery and templating fields consumed by all commands.
+- `pipeline.workspace.root` (local restore target root).
+- `pipeline.storage.*` (remote backend + archive identity derivation).
+- `pipeline.storage.s3.*` identity components used by archive prefix helpers.
+- `pipeline.spool.root` for active audio downloads.
+- `pipeline.cache.root` and `pipeline.cache.s3_audio` for reusable S3 audio cache.
+- `session.session_id`
+- `session.campaign`
+
+## External adapters used
+- `storage.ObjectStore` for `Exists`, `List`, `Download`.
+- `artifacts.Store` (`LocalStore`) for layout and session lock management.
+- `manifest.LocalStore` for manifest decode/validation and identity checks.
+
+## State and manifest behavior
+- Restore is not a pipeline run and does not create a run manifest.
+- Restore uses committed remote current state only:
+  - `current/run_id.txt` must exist and be non-empty.
+  - `current/manifest.json` must decode and match requested session/campaign.
+- Non-dry-run writes restore files to canonical session paths.
+- With `--include-audio`, restore uses the shared S3 audio cache for `audio/**` objects. Cache hits avoid object downloads; cache misses download through spool, install the work file, and populate cache.
+- Manifest install behavior:
+  - validated before replacement.
+  - installed last among download actions.
+  - existing local manifest is preserved if restored manifest validation/install fails.
+- Non-dry-run report persists summary/action status metadata in `reports/restore-latest.json`.
+
+Restore path scope:
+- includes:
+  - `manifest.json`
+  - `transcripts/**`
+  - `artifacts/**`
+  - `previous/**`
+  - `audio/**` only when `--include-audio` is set
+- excludes:
+  - `runs/**`
+  - `logs/**`
+  - `reports/**`
+  - `config/**`
+  - `inputs/**`
+  - remote `current/**` pointer files as local restore targets
+
+## Skip and resume behavior
+- Restore does not participate in stage skip/resume decisions.
+- Restore provides durable local state so subsequent stage commands can resume or rerun based on restored manifest state.
+- Audio cache is outside the workspace and is reused across restore and prepare invocations.
+- Dry-run is read-only and returns plan output only.
+
+## Failure behavior
+- Fails when storage backend is unavailable or archive identity cannot be resolved.
+- Fails when remote current pointer/manifest is missing or invalid.
+- Fails when remote manifest identity mismatches requested campaign/session.
+- Fails on local conflicts unless `--force` is set.
+- Fails fast on session lock acquisition conflict for non-dry-run execution.
+- On execution failure, previously installed files remain; no rollback is performed.
+
+## Tests to inspect before changing
+- `internal/app/restore_test.go`
+- `internal/app/restore_discovery_test.go`
+- `internal/app/restore_plan_test.go`
+- `internal/app/restore_execution_test.go`
+- `internal/app/restore_workflow_test.go`
+- `internal/artifacts/archive_identity_test.go`
+
+## Architectural invariants
+- Restore relies on centralized archive identity/key helpers (`internal/artifacts`) rather than ad hoc key building.
+- `current/run_id.txt` is the remote commit marker; restore must not infer committed state from incidental files.
+- Local path mapping is traversal-safe and constrained to session root.
+- Restore scope is deterministic and path-classified:
+  - include `manifest.json`, `transcripts/**`, `artifacts/**`, `previous/**`
+  - include `audio/**` only with `--include-audio`
+  - exclude `runs/**`, `logs/**`, `reports/**`, `config/**`, `inputs/**`
+- Command remains standalone; no implicit `run --restore` behavior.

+# Internal: Manifest
+
+## Purpose
+Describe Narratio's durable execution state model for session-level and run-level manifests, including lifecycle transitions and persistence behavior.
+
+## Inputs and outputs
+Inputs:
+- Session identity and run identity from app orchestration.
+- Stage transition events and stage result payloads.
+
+Outputs:
+- Session manifest at `{workspace.root}/work/{campaign}/{session_id}/manifest.json`.
+- Run manifest at `{workspace.root}/work/{campaign}/{session_id}/runs/{run_id}/manifest.json`.
+
+## Boundaries
+Owns:
+- Manifest schemas (`Manifest`, `RunManifest`, stage records, error records, input/artifact records).
+- Stage status/action transition methods.
+- Persistent store contract (`manifest.Store`) and local JSON store implementation.
+
+Does not own:
+- Stage implementation details.
+- Path construction policy outside manifest file persistence calls.
+- CLI command behavior.
+
+## Config fields used
+Manifest package itself does not read config directly.
+
+Manifest identity fields are populated by app/stage orchestration from:
+- `session.session_id`
+- `session.campaign`
+- `pipeline.workspace.root`
+- `pipeline.storage.s3.*` (when archive/S3 identity is set)
+
+## External adapters used
+- No external service adapters.
+- Uses local filesystem for persistence via `manifest.LocalStore`.
+
+## State and manifest behavior
+Session manifest model:
+- Tracks durable per-session stage state and provenance (`pending`, `running`, `succeeded`, `failed`, `skipped`, `stale`, `interrupted`).
+- Stores resolved inputs, durable artifacts, stage logs/config refs, and stage metadata.
+
+Run manifest model:
+- Tracks one invocation (`run_id`) with requested stages and force mode.
+- Tracks per-stage action (`run` or `skip`) and per-stage status.
+- Tracks overall run status (`running`, `succeeded`, `failed`).
+
+Persistence behavior:
+- Load validates required identity/timestamp fields and normalizes maps/records.
+- Save updates `updated_at` and writes JSON atomically (temp file + rename).
+- Session and run manifests are saved incrementally before/after stage transitions.
+
+Relationship during execution:
+- Runner updates both manifests for every stage transition.
+- Session manifest is the durable pipeline-progress ledger.
+- Run manifest is invocation history and audit record.
+- Analyze stage outputs are persisted as `kind=scriptorium_artifact` with `source_id=narratio.artifact.<name>` for configured artifact identity.
+
+## Skip and resume behavior
+- Resume and skip decisions are based on session-manifest stage statuses.
+- `--force` reruns selected stages and marks downstream succeeded stages as `stale` in session manifest.
+- Run manifest records whether each stage was executed or skipped in that invocation.
+
+## Failure behavior
+- Stage failure marks both manifests failed for that stage and records error messages/timestamps.
+- Save failures are returned immediately and fail the command.
+- Invalid/malformed manifest files fail load with explicit validation/decode errors.
+
+## Tests to inspect before changing
+- `internal/manifest/manifest_test.go`
+- `internal/manifest/run_manifest_test.go`
+- `internal/manifest/store_test.go`
+- `internal/app/runner_test.go`
+- `internal/app/run_control_test.go`
+- `internal/app/resume_run_stage_test.go`
+
+## Architectural invariants
+- Session manifest is authoritative for stage progression across invocations.
+- Run manifest is invocation-scoped and never replaces session manifest as progress authority.
+- Manifest writes are atomic and deterministic (JSON + newline, temp rename pattern).

+# Stage: analyze
+
+## Purpose
+Execute selected configured Scriptorium artifacts in deterministic dependency order and promote successful outputs to canonical session artifact paths.
+
+## Inputs and outputs
+Inputs:
+- configured artifact definitions from `pipeline.scriptorium.artifacts`;
+- selected artifact filter (`--artifacts`) when provided;
+- resolved artifact sources from resolver/catalog.
+
+Source types used by analyze:
+- built-ins: `narratio.transcript.*`, `narratio.bounds.session`;
+- configured artifacts: `narratio.artifact.<artifact_key>`;
+- canonical previous-session artifacts: `narratio.previous_session.artifact.<artifact_key>`.
+
+Outputs:
+- promoted configured artifact files at each configured `output_path`;
+- stage metadata (`generated_artifacts`, `reused_artifacts`, selected/order info).
+
+## Boundaries
+Owns:
+- runtime artifact catalog construction;
+- selected-artifact planning and dependency ordering;
+- per-input resolution and required/optional handling;
+- Scriptorium render/run invocation;
+- run-local output generation and canonical promotion.
+
+Does not own:
+- prepare-time previous-session hydration;
+- object-store access for previous-session sources;
+- archive promotion policy.

+- `session.campaign`
+- `pipeline.workspace.root`
+- `pipeline.scriptorium.binary`
+- `pipeline.scriptorium.config_path`
+- `pipeline.scriptorium.timeout`
+- `pipeline.scriptorium.render_debug`
+- `pipeline.scriptorium.artifacts.<name>.*`
+
+## External adapters used
+- Scriptorium adapter:
+  - optional `RenderArtifact` when render-debug is enabled;
+  - `RunArtifact` for artifact generation.
+
+## State and manifest behavior
+- If Scriptorium config is absent, or no artifacts are executable after filtering, analyze returns success metadata with `skipped=true`.
+- Builds runtime catalog with built-ins and configured `narratio.artifact.<name>` entries.
+- Non-executable configured artifacts may still be marked available from existing canonical output files.
+- Resolves canonical previous-session sources from local prepared `previous/` cache:
+  - prefers manifest-backed previous input paths when present;
+  - may fall back to current-session `previous/` filesystem paths.
+- Analyze does not call object storage for canonical previous-session source resolution.
+- Required canonical previous-session input missing:
+  - fails with guidance to run `narratio run-stage --force prepare`.
+- Optional missing sources are omitted from adapter input paths.
+
+## Skip and resume behavior
+- Runner-level skip applies when analyze is already `succeeded` and `--force` is not set.
+- Analyze is stage-scoped for resume; no per-artifact manifest resume state.
+- `--artifacts` filters executable artifacts but does not imply force rerun.
+
+## Failure behavior
+- Fails on dependency-order violations, missing required inputs, resolver validation failures, adapter errors, and missing/empty generated outputs.
+- Required unavailable configured artifact source (`narratio.artifact.<name>`) fails before invocation.
+- Required canonical previous-session source fails with prepare-rerun guidance.

+# Stage: archive
+
+## Purpose
+Publish durable run/session state to object storage, then atomically advance remote current state.
+
+## Inputs and Outputs
+Inputs:
+- session manifest and prerequisite stage records
+- run root contents under `runs/{run_id}/`
+- promotion rules with artifact `source` IDs and archive `dest` paths (`archive.promote_artifacts`)
+- effective source-based promotion locks from static config and remote session lock store
+- session-level `previous/**` cache files when present
+
+Outputs:
+- uploaded run files under `{session_prefix}/runs/{run_id}/...`
+- uploaded promoted artifacts under `{session_prefix}/...`
+- uploaded session previous-cache files under `{session_prefix}/previous/...` when present
+- `{session_prefix}/current/manifest.json`
+- `{session_prefix}/current/run_id.txt` written last
+
+## Boundaries
+Owns:
+- Archive enable/disable gate behavior
+- Prerequisite stage success enforcement
+- Run file collection and upload (excluding `audio/`)
+- Promotion rule resolution and upload
+- Promotion lock enforcement
+- Session previous-cache file collection/upload
+- Commit pointer publish order
+
+Does not own:
+- Stage execution before archive
+- Post-archive local cleanup policy execution (handled by app cleanup logic)
+
+## Config Fields Used
+- `pipeline.archive.enabled`
+- `pipeline.archive.upload_run`
+- `pipeline.archive.promote_artifacts`
+- `pipeline.archive.locks`
+- `{session_prefix}/locks.yml` loaded by app orchestration before archive execution
+- `pipeline.storage.s3.bucket`
+- `pipeline.storage.s3.root_prefix`
+- `pipeline.workspace.root`
+- `session.campaign`
+- `session.session_id`
+
+## External Adapters Used
+- Object storage backend (`env.ObjectStore`) for upload/list primitives.
+
+## State and Manifest Behavior
+- Requires `prepare`, `transcribe`, `merge`, `polish`, `normalize`, `trim`, and `analyze` status `succeeded`.
+- Resolves bucket/prefix from manifest identity first, then config fallback.
+- Uploads session `previous/**` files as durable session state when the local `previous/` directory exists.
+- Skips top-level promotion uploads for effective locked sources; run-local uploads still publish.
+- When selected configured artifact keys are supplied, skips promotion rules for unselected `narratio.artifact.<key>` sources; built-in transcript and bounds promotions still publish.
+- Effective locks are the union of `pipeline.archive.locks` and remote `{session_prefix}/locks.yml`; static pipeline locks win on duplicate sources.
+- Writes metadata including:
+  - upload counts/paths
+  - `previous_files_uploaded` and `previous_uploaded_paths`
+  - `skipped_unselected_promotions`
+  - `locked_promotion_count` and `locked_promotions`
+  - `current_manifest_key`
+  - `current_run_id_key`
+  - `current_pointer_written`
+- On skipped archive path, returns metadata with `skipped=true` and pointer not written.
+
+## Skip and Resume Behavior
+- Stage may self-skip (metadata skip) when archive disabled or run upload disabled.
+- Runner-level skip also applies for previously succeeded stage unless forced.
+
+## Failure Behavior
+- Fails on missing prerequisite success, missing object store when required, missing run root, missing unlocked required promotion source, upload failures, or pointer write failures.
+- Locked required promotions are intentional skips and do not fail archive.
+- Pointer semantics are fail-safe: `current/run_id.txt` is not written if prior required uploads fail.
+
+## Tests to Inspect Before Changing
+- `internal/stage/archive_test.go`
+- `internal/app/post_archive_cleanup_test.go`
+
+## Architectural Invariants
+- Run upload excludes `audio/` subtree.
+- Session `previous/**` is archiveable durable input/provenance state, not run-local output.
+- Ordinary `--force` does not override archive locks.
+- Malformed or unreadable remote lock store fails archive-capable execution before promotion.
+- `current/manifest.json` uploads before `current/run_id.txt`.
+- `current/run_id.txt` is the remote publish commit marker.

+
+## State and manifest behavior
+- Ensures workspace layout exists.
+- Materializes canonical input files and audio files.
+- For S3 audio, uses run-scoped spool for active downloads and durable cache for reusable audio files; cache hits copy directly to work audio without downloading the object again.
+- Records `inputs/session.yml` provenance as local `session_config` or remote `session_config.s3`.
+- Resolves campaign-provided stable input paths relative to `campaign.yml`.
+- Resolves session-provided stable input overrides relative to `session.yml`.
+- Scans enabled configured artifact inputs for canonical sources:
+  - `narratio.previous_session.artifact.<artifact_key>`
+- If one or more canonical previous-session requirements exist:
+  - clears managed `previous/` state;
+  - hydrates required/optional previous artifacts from the configured previous session’s committed archive current state;
+  - writes `previous/manifest.json` and hydrated `previous/artifacts/**`;
+  - stores archive-relative artifact paths such as `artifacts/session_recap.md` as `previous/artifacts/session_recap.md`, not `previous/artifacts/artifacts/session_recap.md`;
+  - records hydrated previous inputs in `manifest.Inputs` with source `previous_session_archive.current`.
+- If no canonical previous-session requirements exist, prepare does not manage `previous/`.
+- `manifest.Inputs` is sorted deterministically by `(kind, path)`.
+- S3 audio `manifest.Inputs` retain S3 provenance and include `cache_path`; `spool_path` is present only when the current prepare invocation downloaded the file.
+
+## Required and optional previous-session behavior
+- `previous_session_id` unset:
+  - if any referenced previous artifact is required: fail;
+  - if all referenced previous artifacts are optional: continue and omit them.
+- Previous session archive current pointer or manifest missing:
+  - if any referenced previous artifact is required: fail;
+  - if all referenced previous artifacts are optional: continue and omit missing ones.
+- Missing required previous artifact object: fail.
+- Missing optional previous artifact object: omit.
+- Downloaded previous artifacts must validate as non-empty files.
+
+## Skip and resume behavior
+- Runner-level skip remains authoritative:
+  - if `prepare` already succeeded and run is not forced, `prepare` does not run and no hydration/download occurs.
+- If `prepare` runs (including with `--force`), it owns managed `previous/` state for canonical previous-session inputs.
+
+## Failure behavior
+- Fails on missing required input files, invalid audio-source combinations, empty/duplicate audio inputs, missing object store for S3 modes, and remote access/download/validation errors.
+- For required canonical previous-session inputs, analyze-time missing-input guidance is to rerun:
+  - `narratio run-stage --force prepare`

+- `internal/stage/prepare_previous_test.go`
+- `internal/artifacts/previous_requirements_test.go`
+- `internal/app/runner_test.go`
+
+## Architectural invariants
+- `audio_dir`/`audio_files` and `audio_s3` are mutually exclusive.
+- Storage keys are computed by callers using archive/path helpers; storage adapter receives explicit keys.
+- `prepare` is the only stage that hydrates canonical previous-session cache state.

+Outputs:
+- `transcripts/raw/<speaker>.json` for each input audio file
+
+## Boundaries
+Owns:
+- Discovering prepared audio inputs
+- Deriving speaker ids from audio basenames
+- Parallel WhisperX invocation with bounded concurrency
+- Validating produced JSON and promoting run-local outputs
+
+Does not own:
+- Transcript merge/polish/normalize/trim/analyze

+- `pipeline.whisperx.retry_delay`
+- `pipeline.whisperx.concurrency`
+
+## External Adapters Used
+- WhisperX adapter (`env.WhisperX.Transcribe`).
+
+## State and Manifest Behavior
+- Uses run-local output paths under `runs/{run_id}/transcribe/outputs/...` when run layout is enabled.
+- Validates each generated transcript JSON before promotion.
+- Promotes canonical outputs to `transcripts/raw/*.json`.
+- Records per-file metadata (attempts/status/duration/output path) in stage metadata.
+
+## Skip and Resume Behavior
+- Runner-level skip applies for previously succeeded stage unless forced.
+- On forced upstream reruns, downstream succeeded stages can be marked `stale` by runner logic.
+
+## Failure Behavior
+- Fails if no prepared audio exists, duplicate speaker basenames are detected, adapter output path mismatches expected path, any output JSON is invalid, or one worker fails.
+- Cancels in-flight workers after first terminal error.
+
+## Tests to Inspect Before Changing
+- `internal/stage/transcribe_test.go`

+- Speaker identity is derived from `.flac` basename and must be unique.
+- Every successful speaker output must be valid JSON before promotion.
+- Canonical raw transcript set is the only supported merge input surface.

+## Skip and Resume Behavior
+- Runner-level skip applies when already succeeded and not forced.

+# Internal: Storage
+
+## Purpose
+Document Narratio's remote storage backend contracts and implementations under `internal/adapters/storage`.
+
+## Inputs and outputs
+Inputs:
+- Resolved storage config (`pipeline.storage.*`).
+- Already-loaded environment variables for configured S3 credentials.
+- Bucket-relative object keys and local file paths from app/stage orchestration.
+
+Outputs:
+- Listed/downloaded/uploaded object metadata (`ObjectInfo`).
+- Existence checks and storage-layer errors.
+
+## Boundaries
+Owns:
+- Remote object-store interface and implementation details.
+- S3 client wiring and API calls.
+- Object key normalization and upload/download/list primitives.
+
+Does not own:
+- Session/run prefix semantics.
+- Archive commit order semantics.
+- Manifest updates.

+
+## External adapters used
+Storage package contracts:
+- `ObjectStore` (active remote object-store boundary): `List`, `Download`, `Upload`, `Exists`.
+- `Backend` (archive request boundary): currently implemented with `NoopBackend` only.
+
+Implementations:
+- `S3Backend`: AWS SDK-backed `ObjectStore` implementation.
+- `FakeBackend`: deterministic test `ObjectStore` and archive backend.
+- `NoopBackend`: deterministic no-op archive backend for compatibility wiring.
+
+## State and manifest behavior
+- Storage implementations are stateless with respect to manifest/session lifecycle.
+- Caller supplies fully-qualified bucket-relative keys.
+- Storage layer does not infer campaign/session/run/root-prefix semantics.
+- Caller controls publish ordering; storage layer executes individual operations in the order invoked.
+
+## Skip and resume behavior
+- No storage-level skip/resume behavior.
+- Skip/resume decisions are made by stage/app logic before storage calls occur.
+
+## Failure behavior
+- `NewObjectStoreFromConfig` fails when no remote backend is configured or required S3 config is missing.
+- `S3Backend` constructor fails when required bucket is missing or AWS client setup fails.
+- App command orchestration loads configured filesystem secrets before calling the object-store factory.
+- CRUD operations return contextual errors (including not-found behavior via `Exists`).
+- Key normalization is applied before operations (`\\` to `/`, leading slash trimmed).
+- Remote session loading uses `List` to find the exact `session.yml` key and `Download` to materialize it to a local temp file.

+# Workspace internals
+
+## Purpose
+Define the local durable and run-local workspace model used by stages, manifests, resume, and archive.
+
+## Inputs and Outputs
+Inputs:
+- `pipeline.workspace.root`
+- `session.campaign`
+- `session.session_id`
+- generated `run_id`
+
+Outputs:
+- Session manifest at `{workspace.root}/work/{campaign}/{session_id}/manifest.json`
+- Run manifest at `{workspace.root}/work/{campaign}/{session_id}/runs/{run_id}/manifest.json`
+- Canonical durable session directories and run-local stage trees
+
+## Boundaries
+Owns:
+- Session-level path layout (`inputs/`, `audio/`, `transcripts/`, `artifacts/`, `reports/`, `logs/`, `config/`, `current/`, `runs/`, `previous/`)
+  - `previous/manifest.json` and `previous/artifacts/**` are reserved for previous-session cache state materialized by `prepare` or `restore`
+- Run-local stage sandbox layout under `runs/{run_id}/{stage}/`
+- Session lock acquisition/release (`.lock`)
+
+Does not own:
+- Stage business logic
+- Remote archive semantics (documented in `stage-archive.md`)
+- CLI argument parsing
+
+## Config Fields Used
+- `pipeline.workspace.root`
+- `pipeline.workspace.cleanup_after_archive`
+- `pipeline.spool.root`
+- `pipeline.spool.delete_audio_after_archive`
+- `pipeline.cache.root`
+- `pipeline.cache.s3_audio`
+- `session.campaign`
+- `session.session_id`
+
+## External Adapters Used
+None directly in this subsystem. Stages may use object storage adapters and then write local outputs into this layout.
+
+## State and Manifest Behavior
+- Session state is persisted in the session manifest (`manifest.Manifest`).
+- Invocation history is persisted per run in run manifests under `runs/{run_id}/manifest.json`.
+- During each run, stage outputs are often written run-local first (`runs/{run_id}/{stage}/outputs/...`) and promoted to canonical session paths after stage success.
+- `manifest.Artifacts` entries record `ProducerRunID` for durable outputs.
+- For S3 audio sessions, `prepare` records work/cache paths, S3 provenance, and spool path when the invocation downloaded the object.
+- `previous/**` is reconstructed from configured previous-session requirements; restore uses the previous session's committed current archive rather than treating current-session archived `previous/**` as authoritative.
+- Durable cache state under `pipeline.cache.root` is not workspace state and is preserved by default by `narratio clean`.
+- `narratio clean <id>` removes the session work root and session spool root.
+- `narratio clean --all` removes all local session work under `workspace.root/work` and spool children under `spool.root`.
+- `narratio clean --clear-cache` is the explicit opt-in for deleting matching S3 audio cache entries.
+
+## Skip and Resume Behavior
+- Skip/resume decisions are made in `internal/app` (`run_control.go`, `resume.go`) using stage status in the session manifest.
+- `--force` reruns selected stages and marks downstream previously-succeeded stages as `stale`.
+- Workspace layout is idempotent (`EnsureLayoutFor`) and reused across runs.
+
+## Failure Behavior
+- Failures preserve manifests and run-local files for inspection.
+- Lock conflicts fail fast via `ErrLockConflict`.
+- Cleanup can fail post-archive; failure is recorded in archive stage metadata and returned by the run.
+
+## Tests to Inspect Before Changing
+- `internal/artifacts/local_test.go`
+- `internal/stage/run_local_test.go`
+- `internal/app/run_control_test.go`
+- `internal/app/resume_run_stage_test.go`
+- `internal/app/post_archive_cleanup_test.go`
+
+## Architectural Invariants
+- Session root is campaign-aware: `{workspace.root}/work/{campaign}/{session_id}`.
+- Run roots are always nested: `runs/{run_id}` under the session root.
+- Run-local output promotion must end in canonical session paths.
+- `previous/**` is session-durable state and must not be treated as run-local output scratch state.
+- Automatic post-archive cleanup only targets run-scoped directories and must never delete configured root directories.
+- Manual `clean` may delete session-scoped directories or the `workspace.root/work` directory, but it must preserve configured root directories and reject unsafe targets.

+# Operations
+
+This guide describes the implemented operator lifecycle for Narratio.
+
+For field-level configuration, see [docs/config.md](./config.md). For full command/flag reference, see [docs/cli.md](./cli.md).
+
+## Normal workflow (S3-first path)
+
+1. Create or upload `session.yml`, or pass a local `session.yml` explicitly.
+2. Upload session `.flac` files to object storage under the configured session audio prefix.
+3. Run Narratio:
+
+```bash
+narratio run 2026-04-04
+```
+
+4. Read success output:
+- `narratio run: session <session_id>; executed=<n> skipped=<n>; manifest=<path>`
+- use `narratio session status <session_id>` for inspection.
+
+Notes:
+- default pipeline/session discovery checks system config locations; campaign selection uses `pipeline.campaigns.default_campaign_id` unless `--campaign <id>` or `--campaign-file <path>` is passed.
+- when local `session.yml` discovery misses, positional `<session_id>` loads remote `session.yml` from `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/session.yml`.
+- S3 audio mode requires `session.inputs.audio_s3.prefix` and valid object-store access.
+
+Initialize a remote session skeleton:
+
+```bash
+narratio session init 2026-04-04 --remote
+```
+
+Remote init uses normal default config discovery and writes `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/session.yml`. If `campaign.yml` sets `session_template_file`, init renders that template from the supplied flags and writes concrete YAML. Pass `--config`, `--campaign <id>`, or `--campaign-file <path>` when testing non-system config files. It fails if the object already exists unless `--force` is passed.
+
+Validate before running:
+
+```bash
+narratio session validate 2026-04-04
+```
+
+## Restore workflow
+
+Use restore when local durable session state is missing or stale and archive current state is authoritative.
+
+Dry-run (no local writes):
+
+```bash
+narratio session restore 2026-04-04 --dry-run
+```
+
+Execution:
+
+```bash
+narratio session restore 2026-04-04
+```
+
+Post-restore analyze rerun pattern:
+
+```bash
+narratio analyze 2026-04-04
+```
+
+Restore source-of-truth:
+- remote commit marker: `current/run_id.txt`
+- remote current manifest: `current/manifest.json`
+- configured previous-session requirements are reconstructed from the previous session's remote `current/` state, not from archived `previous/**` objects in the current session.
+
+Restore default scope:
+- includes `manifest.json`, `transcripts/**`, and `artifacts/**` from the current session archive.
+- includes `previous/**` only when configured previous-session artifact inputs require it; restore hydrates those files the same way `prepare` would.
+- includes `audio/**` only with `--include-audio`
+- excludes `runs/**`, `logs/**`, `reports/**`, `config/**`, `inputs/**`, and `current/**` (except remote `current/manifest.json` as source)
+
+Reset local state before restore testing:
+
+```bash
+narratio clean 2026-04-04 --dry-run
+narratio clean 2026-04-04
+narratio session restore 2026-04-04 --include-audio
+```
+
+`clean` removes the local session work directory and session spool directory. It preserves the durable S3 audio cache by default, so repeated restore or forced prepare tests do not re-download large audio files.
+
+## Local filesystem layout and state artifacts
+
+Session root:
+- `{workspace.root}/work/{campaign}/{session_id}/`
+
+Primary state:
+- `manifest.json`: session-level stage state.
+- `runs/{run_id}/manifest.json`: invocation-level state.
+- `.lock`: session lock while a modifying command is active.
+- `inputs/campaign.yml`, `inputs/session.yml`, and `inputs/pipeline.resolved.yml`: materialized config inputs for the run.
+
+Canonical session directories:
+- `inputs/`
+- `audio/`
+- `transcripts/`
+- `artifacts/`
+- `previous/`
+- `reports/`
+- `logs/`
+- `config/`
+- `current/`
+- `runs/`
+
+Run-local stage directories:
+- `runs/{run_id}/{stage}/` with stage-local `outputs/`, `logs/`, `reports/`, `config/`, `scratch/`.
+
+Behavior:
+- directory creation is idempotent.
+- stage outputs are generally generated run-local first, then promoted to canonical paths on success.
+- restore installs downloaded files to canonical session paths and does not recreate historical run sandboxes.
+
+## Analyze artifact execution lifecycle
+
+Analyze executes configured artifacts from `pipeline.scriptorium.artifacts`.
+
+Execution model:
+- executable set = enabled artifacts, filtered by `--artifacts` when provided.
+- artifact-to-artifact dependencies are declared via `depends_on`.
+- selected artifacts run in deterministic dependency order.
+- after each successful artifact run, output is promoted to configured canonical `output_path`.
+
+Configured artifact source reuse:
+- a non-executable configured artifact can satisfy inputs if its configured output file already exists and is valid.
+- reused configured artifact provenance is `filesystem.disabled_artifact_output`.
+
+`--artifacts` behavior:
+- accepted on `run`, `resume`, `run-stage analyze`, `run-stage archive`, `analyze`, and `publish`.
+- filters analyze execution and configured artifact promotions.
+- built-in transcript and bounds promotions are not filtered.
+- does not imply force on `run`, `resume`, or `run-stage`; `narratio analyze` is force-by-design.
+- `publish` is force-by-design and accepts `--artifacts` for configured artifact promotions.
+
+Canonical previous-session input behavior:
+- canonical sources use `narratio.previous_session.artifact.<artifact_key>`.
+- these inputs are hydrated by `prepare` and by `restore`; `analyze` expects the local previous cache to already exist.
+- if analyze fails due to missing canonical previous cache, rerun:
+  - `narratio run-stage prepare <id> --force`
+  - or `narratio session restore <id>` when remote archive current state is authoritative.
+
+## Remote archive layout and publish contract
+
+Preferred manual publish command:
+
+```bash
+narratio publish <id>
+```
+
+`publish` is equivalent to `narratio run-stage archive <id> --force`; use `run-stage` when you need the general single-stage command form.
+
+When archive is enabled and run upload is enabled, archive publishes under:
+
+- session prefix: `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/`
+- run prefix: `{session_prefix}/runs/{run_id}/`
+
+Archive uploads:
+- run record files from run root (excluding `audio/`).
+- promoted files from explicit `archive.promote_artifacts` rules.
+- mutable session locks from helper commands live at `{session_prefix}/locks.yml`.
+
+Publish order:
+1. upload `current/manifest.json`
+2. upload `current/run_id.txt` last
+
+`current/run_id.txt` is the remote commit marker.
+
+Archive promotion is explicit and source-based:
+- Narratio does not auto-promote all generated analyze artifacts.
+- each rule resolves `source` through the artifact resolver/catalog model, then uploads to `dest`.
+- missing required promotion sources fail archive stage.
+- missing optional promotion sources are skipped.
+- invalid resolved artifacts fail archive stage.
+- `archive.locks` skips top-level promotion overwrites for locked sources while run-local uploads still publish.
+- remote locks from `{session_prefix}/locks.yml` are merged with static `archive.locks`; static locks win on duplicate sources.
+- locked required promotions are treated as intentional successful skips and are recorded in archive metadata.
+
+Lock helper behavior:
+- `narratio session locks <id>` lists effective static and remote locks.
+- `narratio session locks add <id> <source> --reason <text>` writes a remote lock.
+- `narratio session locks add <id> <source> --force --reason <text>` updates an existing remote lock reason.
+- `narratio session locks remove <id> <source>` removes only a remote lock.
+- `locks remove` cannot remove static pipeline locks.
+- remote lock writes check whether the lock store exists, but are not compare-and-swap atomic.
+
+## Resume, retry, restore, and safe rerun behavior
+
+Default skip:
+- `run` and `run-stage` skip already-succeeded stages unless `--force` is set.
+
+Resume:
+- `resume` starts at first non-succeeded stage.
+- `resume --force` runs full stage order.
+
+Restore conflict policy:
+- restore classifies local differences as conflicts.
+- without `--force`, restore fails when conflicts exist.
+- with `--force`, conflicting local files are overwritten by remote archive files.
+
+Forced reruns:
+- force-rerunning an upstream succeeded stage marks downstream succeeded stages as `stale`.
+- ordinary `--force` does not override archive locks.
+
+Safe rerun pattern:
+1. rerun the changed stage with `--force`.
+2. run `resume` to rebuild downstream stages.
+
+## Cleanup behavior
+
+Automatic post-archive cleanup is considered only when archive stage executed and succeeded.
+
+Automatic cleanup toggles:
+- `pipeline.spool.delete_audio_after_archive=true` deletes run-scoped spool audio.
+- `pipeline.workspace.cleanup_after_archive=true` deletes run-scoped local run directory.
+
+Manual cleanup:
+- `narratio clean <id>` deletes `{workspace.root}/work/{campaign}/{session_id}` and `{spool.root}/{campaign}/{session_id}`.
+- `narratio clean --all` deletes all local session work under `{workspace.root}/work` and all spool children under `{spool.root}`.
+- `--dry-run` prints targets without deleting.
+- `--clear-cache` also removes matching S3 audio cache files. Without it, cache is preserved.
+
+The S3 audio cache under `pipeline.cache.root` is durable input cache state, not workspace or spool state. Automatic cleanup and default manual cleanup do not delete it.
+
+Cleanup eligibility gates:
+- archive enabled
+- archive run upload enabled
+- run record upload completed
+- current pointer write completed (`current/run_id.txt` written)
+
+No cleanup for failed/incomplete/unarchived/archive-skipped runs.
+
+## Failure and recovery playbooks
+
+After run failure, Narratio keeps:
+- session manifest
+- run manifest
+- run-local artifacts/logs/config/reports
+
+Failed or incomplete runs remain local-only.
+
+After restore failure:
+- already-installed restore files remain in place.
+- restore does not roll back prior successful installs.
+- existing local manifest is preserved if restored manifest validation/install fails.
+
+Recommended recovery:
+
+1. inspect state:
+
+```bash
+narratio session status 2026-04-04
+```
+
+This reports local manifest state, committed remote current state, expected remote transcript/artifact availability, and archive locks.
+
+2. for restore-specific checks, run:
+
+```bash
+narratio session restore 2026-04-04 --dry-run
+```
+
+3. fix root cause (config/input/credentials/storage/service availability).
+4. continue with `resume`, or targeted `run-stage <stage> <id> --force` followed by `resume`.
+
+## Restore report
+
+Non-dry-run restore writes a durable report at:
+- `reports/restore-latest.json`
+
+Report content includes:
+- identity (`campaign`, `session_id`, `run_id`)
+- mode flags (`dry_run`, `force`, `include_audio`)
+- plan counts and execution counts
+- per-action status
+
+Dry-run does not write restore report files.
+
+## Operational caveats
+
+- `session status <session_id>` uses normal config/session loading, including remote session fallback.
+- `session status <session_id>` includes the same promoted remote output availability view as `session artifacts <session_id> --remote` when storage is configured.
+- local and S3 audio input modes are mutually exclusive.
+- archive publish requires upstream stages through `analyze` to be `succeeded`.
+- required configured artifact promotions for unselected `--artifacts` keys are skipped intentionally; selected required promotions still fail if their files are missing.
+- restore requires configured remote object storage and committed remote current state.

+# Roadmap: Campaign Registry
+
+Status: Implemented
+
+## Problem
+
+Narratio currently treats campaign configuration as one selected
+`campaign.yml` file:
+
+- command flags use `--campaign <path>`;
+- default discovery searches fixed system file locations;
+- `campaign.yml` uses `campaign:` as the identity field.
+
+That model works for a single campaign, but it is awkward for installations
+that manage multiple campaigns. Operators need to pass file paths or maintain a
+single global campaign config, while the newer session-oriented CLI already
+uses concise positional session IDs and remote session lookup.
+
+The campaign selection model should become ID-based and pipeline-owned.
+Pipeline config should describe where campaigns live, commands should select a
+campaign by ID, and each campaign directory should contain its stable campaign
+materials.
+
+## Target Model
+
+`pipeline.yml` owns the campaign registry:
+
+    campaigns:
+      root: /usr/local/share/narratio/campaigns
+      default_campaign_id: dilfs
+
+Campaign files live at the conventional path:
+
+    {campaigns.root}/{campaign_id}/campaign.yml
+
+The first implementation should use only the conventional path. Recursive
+discovery of every `campaign.yml` under `campaigns.root` is deferred to a
+future stage.
+
+Each campaign file uses `campaign_id` as the canonical identity field:
+
+    campaign_id: dilfs
+    session_template_file: ./session.template.yml
+    inputs:
+      speakers_file: ./speakers.yml
+      autocorrect_file: ./autocorrect.yml
+      glossary_file: ./glossary.yml
+
+Campaign-relative files continue to resolve relative to the selected
+`campaign.yml`, including stable input files and `session_template_file`.
+
+The public CLI changes from path-based campaign selection to ID-based campaign
+selection:
+
+- `--campaign <id>` selects a campaign ID.
+- `--campaign-file <path>` explicitly loads one campaign file for
+  development, tests, and unusual local workflows.
+- `--campaign` and `--campaign-file` are mutually exclusive.
+
+If neither `--campaign` nor `--campaign-file` is passed, Narratio uses
+`pipeline.campaigns.default_campaign_id`. If no campaign can be selected,
+commands fail clearly before session loading or stage execution.
+
+Resolved campaign ID remains the campaign segment used for:
+
+- workspace paths;
+- spool paths;
+- S3 session prefixes;
+- remote `session.yml` lookup;
+- archive locks and promoted output keys;
+- session/campaign mismatch validation;
+- status, plan, restore, and helper output.
+
+## Compatibility Policy
+
+This is a breaking public/config contract change.
+
+After the cutover:
+
+- `--campaign` no longer accepts a filesystem path;
+- default fixed campaign file discovery is removed;
+- `campaign:` is no longer accepted in `campaign.yml`;
+- `campaign_id:` is required.
+
+Keep `--campaign-file` as the only explicit file override. Do not retain hidden
+aliases for the old `--campaign <path>` behavior.
+
+## Implementation Stages
+
+### Stage 1: Add Campaign Registry Selection
+
+Status: Implemented
+
+Add the registry model and switch command loading to resolve campaigns through
+pipeline config.
+
+Implementation requirements:
+
+- Add `pipeline.campaigns.root`.
+- Add `pipeline.campaigns.default_campaign_id`.
+- Add `campaign_id` to campaign config and make it the canonical identity.
+- Resolve pipeline config first, then campaign selection.
+- Use this selection order:
+  1. explicit `--campaign-file <path>`;
+  2. explicit `--campaign <id>`;
+  3. `pipeline.campaigns.default_campaign_id`;
+  4. fail clearly.
+- For ID selection, load `{campaigns.root}/{campaign_id}/campaign.yml`.
+- Validate that the loaded `campaign_id` matches the selected ID.
+- Reject `--campaign` with `--campaign-file`.
+- Preserve strict YAML decoding.
+- Preserve campaign-relative stable input and session template resolution.
+- Keep storage details behind the existing storage adapter and object-store
+  helper.
+- Keep remote session lookup and archive key construction based on the
+  resolved campaign ID.
+
+Acceptance criteria:
+
+- Commands can run with only a pipeline config and the pipeline default
+  campaign ID.
+- Commands can select another campaign with `--campaign <id>`.
+- Commands can load a specific file with `--campaign-file <path>`.
+- Existing session loading, remote session fallback, prepare materialization,
+  restore, archive, locks, clean, analyze, and publish behavior continue to use
+  the same resolved campaign identity.
+- No generic config registry framework is introduced.
+
+### Stage 2: Remove Old Single-File Campaign Behavior
+
+Status: Implemented
+
+Remove the old public campaign file model after registry selection is in
+place.
+
+Implementation requirements:
+
+- Remove fixed default campaign config discovery from command loading.
+- Remove `DefaultCampaignConfigSearchPaths` and related path-only resolution if
+  no current tests or helpers still need them.
+- Remove support for `campaign:` from `campaign.yml`.
+- Update validation errors to refer to `campaign_id`.
+- Update examples to use campaign directories and `campaign_id`.
+- Update current-behavior docs to document:
+  - `pipeline.campaigns.root`;
+  - `pipeline.campaigns.default_campaign_id`;
+  - `campaign_id`;
+  - `--campaign <id>`;
+  - `--campaign-file <path>`.
+- Update troubleshooting examples that currently pass `--campaign <path>`.
+
+Acceptance criteria:
+
+- `campaign.yml` files with `campaign:` fail strict decoding.
+- `--campaign /path/to/campaign.yml` is treated as a campaign ID and fails
+  unless that ID exists under `campaigns.root`.
+- `--campaign-file /path/to/campaign.yml` is the supported file override.
+- User-facing docs no longer describe fixed campaign config discovery.
+
+## Test Guidance
+
+Focused tests:
+
+- `go test ./internal/config -v`
+- `go test ./internal/app -v`
+- `go test ./internal/stage -run Prepare -v`
+
+Full validation:
+
+- `go test ./...`
+
+Config tests to add or update:
+
+- strict decode accepts `pipeline.campaigns.root`;
+- strict decode accepts `pipeline.campaigns.default_campaign_id`;
+- strict decode accepts `campaign_id`;
+- selected campaign ID mismatch fails;
+- missing campaign root fails when ID selection is needed;
+- missing default campaign ID fails when no explicit campaign selector is
+  passed;
+- old `campaign:` fails after Stage 2.
+
+App tests to add or update:
+
+- `--campaign <id>` resolves `{campaigns.root}/{id}/campaign.yml`;
+- omitted `--campaign` uses `pipeline.campaigns.default_campaign_id`;
+- `--campaign-file` loads an explicit campaign file;
+- `--campaign` plus `--campaign-file` fails;
+- remote session fallback uses the resolved campaign ID;
+- `session init`, `run`, `run-stage`, `resume`, `analyze`, `publish`, `clean`,
+  and `session` subcommands all use the same campaign selection path;
+- path-based `--campaign` examples and tests are removed after Stage 2.
+
+## Documentation Guidance
+
+Update current-behavior docs only after implementation lands:
+
+- `docs/config.md`
+- `docs/cli.md`
+- `docs/operations.md`
+- `docs/troubleshooting.md`
+- relevant files under `docs/internal/`
+- `examples/`
+
+Planned campaign registry behavior belongs only in this roadmap until the code,
+tests, examples, and current-behavior docs are updated.
+
+## Architecture Guardrails
+
+- Keep Narratio explicit and stage-driven.
+- Do not introduce a generic configuration registry or workflow framework.
+- Keep YAML decoding strict.
+- Keep defaults centralized and testable.
+- Keep campaign-relative path resolution centralized.
+- Use centralized S3 and workspace path helpers.
+- Keep storage details behind `storage.ObjectStore`.
+- Keep secret-backed object-store construction in `internal/app`.
+- Preserve manifest-driven resume and restore behavior.
+- Do not store raw secrets in campaign configs, manifests, logs, generated
+  configs, or archive metadata.
+
+## Assumptions
+
+- The canonical pipeline schema is grouped under `campaigns`.
+- The canonical campaign identity field is `campaign_id`.
+- `--campaign` means campaign ID.
+- `--campaign-file` is retained as an explicit override.
+- Recursive discovery is planned but not part of the first implementation.
+- Existing production configs can be migrated from `campaign:` to
+  `campaign_id:` and from `--campaign <path>` to `--campaign <id>` or
+  `--campaign-file <path>`.

+# Roadmap: Legacy Config Cleanup
+
+Status: Implemented
+
+## Problem
+
+Narratio's current pipeline config schema still accepts fields that predate the current storage, artifact, and previous-session models:
+
+- `pipeline.storage.bucket`
+- `pipeline.storage.prefix`
+- `pipeline.analyzer.*`
+- `previous_session_artifact`
+
+These names make the config reference harder to trust because they suggest supported behavior that operators should no longer use. The modern interface is:
+
+- `pipeline.storage.s3.*` for remote storage.
+- Scriptorium configured artifacts under `pipeline.scriptorium.artifacts`.
+- Canonical artifact source IDs such as `narratio.artifact.<configured_artifact_key>`.
+- Canonical previous-session artifact sources such as `narratio.previous_session.artifact.<configured_artifact_key>`.
+
+Strict YAML decoding should reject removed legacy fields once this cleanup lands.
+
+## Current State
+
+`pipeline.storage.bucket` and `pipeline.storage.prefix` were inert compatibility fields and have been removed:
+
+- They are no longer present on `config.StorageConfig`.
+- Strict decoding rejects them.
+- Runtime S3 behavior uses `pipeline.storage.s3.bucket` and `pipeline.storage.s3.root_prefix`.
+- No current code reads the top-level storage bucket or prefix fields.
+
+`pipeline.analyzer.*` was legacy code surface and has been removed:
+
+- `config.PipelineConfig` no longer includes analyzer config.
+- Strict decoding rejects `pipeline.analyzer`.
+- `stage.Env` no longer exposes an analyzer runner, and `internal/adapters/analyzer` has been deleted.
+- Modern analyze execution is Scriptorium-backed; the analyzer adapter is not used by current stage execution.
+
+`previous_session_artifact` was a live legacy behavior and has been removed:
+
+- Config validation rejects it as an unsupported Scriptorium input source.
+- The analyze stage no longer has path-based previous-artifact resolution through `inputs.<name>.path`.
+- Tests cover canonical previous-session sources and the rejection of the legacy source.
+- The canonical replacement is `narratio.previous_session.artifact.<configured_artifact_key>`, resolved through the previous-session cache/catalog model.
+
+## Target Model
+
+The pipeline config schema should expose only current behavior:
+
+- Remote storage is configured only through `pipeline.storage.s3.*`.
+- Generated artifacts are configured only through `pipeline.scriptorium.artifacts`.
+- Scriptorium artifact inputs use canonical source IDs.
+- Previous-session artifact inputs use `narratio.previous_session.artifact.<configured_artifact_key>`.
+- Unknown legacy fields fail strict YAML decoding.
+
+No compatibility aliases should remain unless a future migration requirement explicitly reintroduces them.
+
+## Cleanup Order
+
+### Stage 1: Remove Inert Storage Compatibility Fields
+
+Status: Implemented
+
+Remove `pipeline.storage.bucket` and `pipeline.storage.prefix`.
+
+Implementation requirements:
+
+- Delete `StorageConfig.Bucket` and `StorageConfig.Prefix`.
+- Keep `StorageConfig.Backend` and `StorageConfig.S3`.
+- Confirm all runtime storage paths continue to use `storage.s3.bucket` and `storage.s3.root_prefix`.
+- Update examples and docs to remove top-level storage `bucket` and `prefix`.
+- Add or update strict-decode tests proving `pipeline.storage.bucket` and `pipeline.storage.prefix` are rejected.
+
+Acceptance criteria:
+
+- Existing S3 workflows still pass with `pipeline.storage.s3.bucket`.
+- Pipeline configs containing top-level `storage.bucket` or `storage.prefix` fail to load.
+- No docs or examples present those fields as available.
+
+### Stage 2: Remove Legacy Analyzer Schema and Adapter Surface
+
+Status: Implemented
+
+Remove the unused analyzer configuration and adapter contract.
+
+Implementation requirements:
+
+- Delete `PipelineConfig.Analyzer`.
+- Delete `AnalyzerConfig` and `ArtifactSettings`.
+- Remove analyzer timeout validation.
+- Remove `stage.Env.Analyzer`.
+- Delete `internal/adapters/analyzer` if no remaining code imports it.
+- Remove `pipeline.analyzer.*` from tests, examples, and docs.
+- Add or update strict-decode tests proving `pipeline.analyzer` is rejected.
+
+Acceptance criteria:
+
+- Analyze behavior remains fully Scriptorium-backed.
+- No runtime code imports `internal/adapters/analyzer`.
+- Pipeline configs containing `pipeline.analyzer` fail to load.
+- Contributor and internal adapter docs no longer list the analyzer adapter.
+
+### Stage 3: Remove Path-Based Previous Session Artifact Source
+
+Status: Implemented
+
+Remove `previous_session_artifact` and require canonical previous-session artifact sources.
+
+Implementation requirements:
+
+- Remove `previous_session_artifact` from supported Scriptorium input sources.
+- Remove analyze-stage special-case handling that resolves `inputs.<name>.path` for previous artifacts.
+- Keep canonical handling for `narratio.previous_session.artifact.<configured_artifact_key>`.
+- Rewrite tests that use `previous_session_artifact` to use canonical sources and prepared previous-cache fixtures.
+- Add validation tests proving `previous_session_artifact` is rejected.
+- Update docs to remove the legacy path-based source and document only canonical previous-session sources.
+
+Acceptance criteria:
+
+- `pipeline.scriptorium.artifacts.*.inputs.*.source: previous_session_artifact` fails validation.
+- Canonical previous-session sources continue to work for required and optional inputs.
+- Prepare/restore previous-cache behavior remains unchanged.
+- No docs or examples mention `previous_session_artifact` as supported.
+
+## Test Guidance
+
+Run focused tests after each stage:
+
+- `go test ./internal/config -v`
+- `go test ./internal/stage -run Analyze -v`
+- `go test ./internal/app -v`
+- `go test ./...`
+
+For Stage 1, focus on config load/strict-decode and S3 workflow regression tests.
+
+For Stage 2, focus on compile-time removal, config strict-decode tests, and full app/stage tests to catch stale adapter references.
+
+For Stage 3, focus on Scriptorium config validation, analyze-stage input resolution, previous-cache behavior, and restore/analyze workflows.
+
+## Documentation Updates
+
+Update current-behavior docs only after the corresponding code removal lands:
+
+- `docs/config.md`
+- `docs/cli.md`, only if command behavior text references removed fields.
+- `docs/operations.md`, only if operator workflow text references removed fields.
+- `docs/internal/stage-analyze.md`
+- `docs/internal/adapters.md`
+- `examples/pipeline.full.annotated.yml`
+- `examples/pipeline.production.yml`
+
+Do not preserve removed fields in examples as compatibility notes. The goal is to make strict config behavior and documentation line up.
+
+## Assumptions
+
+- This is a hard cleanup; no backward-compatible aliases are retained.
+- Current production configs can be migrated to `storage.s3.*`, Scriptorium artifacts, and canonical previous-session sources before this lands.
+- Removing the unused analyzer adapter does not block any active stage behavior.
+- The cleanup should be implemented in the listed order so inert schema removal is separated from behavior removal.

+# Roadmap: Session-Oriented CLI Cleanup
+
+Status: Implemented
+
+## Problem
+
+Narratio's public CLI has accumulated too many top-level commands. Several
+commands are session-scoped operator helpers, but they currently appear as
+independent top-level verbs:
+
+- `plan`
+- `status`
+- `restore`
+- `artifacts list`
+- `locks`
+- `session validate`
+- `session init`
+
+This makes the command surface harder to learn because the CLI does not clearly
+separate primary workflow actions from session inspection, initialization,
+restore, and helper operations.
+
+## Target Model
+
+Keep primary workflow commands at top level:
+
+- `run`
+- `run-stage`
+- `resume`
+- `analyze`
+- `publish`
+- `clean`
+- `session`
+
+Keep `clean` top-level because it can operate on one session or all local
+sessions and is a workspace maintenance command, not only a session helper.
+
+Move session-scoped helper commands under `narratio session` and use positional
+session identifiers:
+
+- `narratio session init <session_id> [--remote|--output <path>] [--flags]`
+- `narratio session validate <session_id> [--flags]`
+- `narratio session status <session_id> [--flags]`
+- `narratio session plan <session_id> [--flags]`
+- `narratio session restore <session_id> [--flags]`
+- `narratio session artifacts <session_id> [--remote] [--flags]`
+- `narratio session locks <session_id> [--flags]`
+- `narratio session locks add <session_id> <source> [--reason <text>] [--force] [--flags]`
+- `narratio session locks remove <session_id> <source> [--flags]`
+
+Update top-level workflow commands to use positional session identifiers:
+
+- `narratio run <session_id> [--flags]`
+- `narratio resume <session_id> [--flags]`
+- `narratio analyze <session_id> [--flags]`
+- `narratio publish <session_id> [--flags]`
+- `narratio run-stage <stage> <session_id> [--flags]`
+
+The positional session ID replaces `--session-id` as the primary public
+interface. Existing `--config`, `--campaign`, `--session`, and
+`--previous-session-id` flags remain available where they are meaningful.
+
+## Command Mapping
+
+| Current command | Target command |
+| --- | --- |
+| `narratio run --session-id <id>` | `narratio run <id>` |
+| `narratio resume --session-id <id>` | `narratio resume <id>` |
+| `narratio analyze --session-id <id>` | `narratio analyze <id>` |
+| `narratio publish --session-id <id>` | `narratio publish <id>` |
+| `narratio run-stage [flags] <stage> --session-id <id>` | `narratio run-stage <stage> <id> [flags]` |
+| `narratio plan --session-id <id>` | `narratio session plan <id>` |
+| `narratio status --session-id <id>` | `narratio session status <id>` |
+| `narratio restore --session-id <id>` | `narratio session restore <id>` |
+| `narratio artifacts list --session-id <id>` | `narratio session artifacts <id>` |
+| `narratio locks --session-id <id>` | `narratio session locks <id>` |
+| `narratio locks add --session-id <id> <source>` | `narratio session locks add <id> <source>` |
+| `narratio locks remove --session-id <id> <source>` | `narratio session locks remove <id> <source>` |
+| `narratio session validate --session-id <id>` | `narratio session validate <id>` |
+| `narratio session init --session-id <id>` | `narratio session init <id>` |
+| `narratio clean --session-id <id>` | `narratio clean <id>` |
+| `narratio clean --all` | unchanged |
+
+`clean` remains top-level, but its session-scoped form should also move from
+`--session-id` to positional `<session_id>` for consistency.
+
+## Compatibility Policy
+
+This is a hard public CLI cleanup after the migration step lands.
+
+During Step 1, old forms may remain as compatibility aliases to keep the
+implementation reviewable. During Step 2, remove the old forms from command
+dispatch, tests, docs, and examples:
+
+- remove top-level `plan`;
+- remove top-level `status`;
+- remove top-level `restore`;
+- remove top-level `artifacts`;
+- remove top-level `locks`;
+- remove `--session-id` from the public command syntax for session-aware
+  commands.
+
+Do not keep long-term deprecated aliases unless a later roadmap explicitly
+chooses a compatibility window.
+
+`status --manifest` does not fit the session-oriented command shape. Remove it
+from the public CLI in this cleanup. If direct manifest inspection is needed
+later, add a separate diagnostic command in a future roadmap rather than keeping
+it as a special case in `session status`.
+
+## Implementation Step 1: Add New Session-Oriented Interface
+
+Status: Implemented
+
+Add the target command forms while preserving current behavior internally.
+
+Implementation requirements:
+
+- Add positional session ID parsing helpers in `internal/app`.
+- Keep the existing `loadCommandConfig` behavior and populate
+  `config.SessionLoadOptions.SessionID` from the positional ID.
+- Add or update command wrappers:
+  - `Run(ctx, args, out)` parses `run <session_id>`.
+  - `Resume(ctx, args, out)` parses `resume <session_id>`.
+  - `Analyze(ctx, args, out)` parses `analyze <session_id>`.
+  - `Publish(ctx, args, out)` parses `publish <session_id>`.
+  - `RunStage(ctx, args, out)` parses `run-stage <stage> <session_id>`.
+  - `Clean(ctx, args, out)` parses `clean <session_id>` and keeps
+    `clean --all`.
+- Extend `Session(ctx, args, out)` dispatch to support:
+  - `init <session_id>`
+  - `validate <session_id>`
+  - `status <session_id>`
+  - `plan <session_id>`
+  - `restore <session_id>`
+  - `artifacts <session_id>`
+  - `locks <session_id>`
+  - `locks add <session_id> <source>`
+  - `locks remove <session_id> <source>`
+- Keep storage access through the existing app-level object-store helper.
+- Keep AWS SDK details behind storage adapters.
+- Keep the runner, stages, manifest behavior, archive behavior, restore
+  planning, lock semantics, and artifact catalog behavior unchanged.
+
+Acceptance criteria:
+
+- New forms execute the same code paths and produce equivalent results.
+- Positional session ID mismatch with concrete local or remote `session.yml`
+  fails through existing session identity checks.
+- Remote session fallback still uses the positional session ID as the lookup
+  value.
+- Current command tests cover the new forms before old forms are removed.
+
+## Implementation Step 2: Remove Old Public Forms
+
+Status: Implemented
+
+Remove compatibility aliases and make the session-oriented interface the only
+documented and supported public CLI.
+
+Implementation requirements:
+
+- Remove top-level dispatch for:
+  - `plan`
+  - `status`
+  - `restore`
+  - `artifacts`
+  - `locks`
+- Remove `--session-id` flags from public session-aware commands.
+- Keep `--previous-session-id` as an expected previous-session identity flag.
+- Keep explicit `--session <path>` for loading a local concrete session file,
+  but still require the positional session ID for commands that operate on a
+  session.
+- Remove `status --manifest`.
+- Update usage text and invalid-command errors.
+- Update `docs/cli.md` and `docs/operations.md` to use only the new forms.
+- Update any roadmap docs that mention old helper command names.
+- Update tests to expect old top-level helper commands and `--session-id` forms
+  to fail.
+
+Acceptance criteria:
+
+- Top-level command list is exactly:
+  - `run`
+  - `run-stage`
+  - `resume`
+  - `analyze`
+  - `publish`
+  - `clean`
+  - `session`
+- All session-oriented commands use `narratio session <subcommand>
+  <session_id> [--flags]`, except nested lock mutation forms, which use
+  `narratio session locks add|remove <session_id> <source> [--flags]`.
+- `clean <session_id>` and `clean --all` remain top-level.
+- Current-behavior docs and tests no longer advertise `--session-id`.
+
+## Test Guidance
+
+Focused tests:
+
+- `go test ./internal/app -run TestExecute -v`
+- `go test ./internal/app -run 'Session|Status|Restore|Clean|Locks|Artifacts|Plan|RunStage|Analyze|Publish' -v`
+- `go test ./internal/config -v`
+
+Full validation:
+
+- `go test ./...`
+
+Test cases to add or update:
+
+- `run <session_id>` loads local and remote sessions through the existing
+  config path.
+- `resume <session_id>`, `analyze <session_id>`, and `publish <session_id>`
+  preserve current behavior.
+- `run-stage <stage> <session_id>` preserves current run-stage output and
+  force/artifact-selection behavior.
+- `session plan <session_id>` replaces top-level `plan`.
+- `session status <session_id>` replaces top-level session status.
+- `session validate <session_id>` replaces `session validate --session-id`.
+- `session init <session_id>` writes the same local or remote concrete
+  `session.yml`.
+- `session restore <session_id>` preserves restore planning/execution.
+- `session artifacts <session_id> --remote` preserves promoted-output
+  availability reporting.
+- `session locks <session_id>`, `session locks add <session_id> <source>`, and
+  `session locks remove <session_id> <source>` preserve static/remote lock
+  semantics.
+- `clean <session_id>` preserves session cleanup behavior, while `clean --all`
+  remains unchanged.
+- Old top-level helper commands fail after Step 2.
+- `--session-id` fails after Step 2.
+- `status --manifest` fails after Step 2.
+
+## Documentation Guidance
+
+Update only after implementation lands:
+
+- `docs/cli.md`
+- `docs/operations.md`
+- any internal docs that list command names or examples
+
+Keep planned behavior only in this roadmap until the command refactor is
+implemented.
+
+## Architecture Guardrails
+
+- Keep Narratio explicit and stage-driven.
+- Do not introduce a generic workflow or command framework abstraction.
+- Reuse existing app command helpers where practical.
+- Keep config loading strict and centralized.
+- Keep storage details behind `storage.ObjectStore`.
+- Keep secret-backed object-store construction in `internal/app`.
+- Preserve manifest-driven resume and restore behavior.
+- Treat command renaming as a public CLI contract change, not a runtime stage
+  behavior change.

+# Roadmap: Publish Contract
+
+Status: Planned
+
+## Problem
+
+Narratio currently uses several terms for one operator-facing concept:
+
+- `archive` is the stage that uploads run state and commits remote current
+  state.
+- `publish` is the convenience command that force-runs the archive stage.
+- `promote`, `promoted`, and `promote_artifacts` describe configured top-level
+  remote output writes.
+
+This mixed vocabulary makes the public contract harder to explain. Operators
+should not need to distinguish "archive the run", "publish the run", and
+"promote artifacts" when these are all part of the same publish action.
+
+The public model should use:
+
+- `publish` for the stage, command, config section, and action;
+- `published` for an expected remote output that exists at its top-level
+  current destination;
+- `publish rules` for the configured source-to-destination output rules;
+- `locked` for sources whose top-level published destination must not be
+  overwritten;
+- `run history` for immutable per-run records under `runs/<run_id>/`.
+
+## Target Model
+
+The public stage is `publish`.
+
+The convenience command:
+
+    narratio publish <session_id>
+
+is equivalent to:
+
+    narratio run-stage publish <session_id> --force
+
+Pipeline configuration uses `publish`:
+
+    publish:
+      enabled: true
+      upload_run: true
+      outputs:
+        - source: narratio.transcript.final_trimmed
+        - source: narratio.artifact.session_recap
+      locks:
+        - source: narratio.artifact.session_recap
+          reason: Final recap was manually edited.
+
+Publish output rules are source-based. Each rule writes one artifact source to
+a top-level remote destination. If `dest` is omitted, Narratio derives the
+destination from the artifact registry or configured artifact output path.
+
+The mutable remote lock store remains:
+
+    {session_prefix}/locks.yml
+
+Remote availability output uses `published`:
+
+    Published:
+    - narratio.transcript.final_trimmed remote=published
+    - narratio.artifact.session_recap locked remote=published
+
+The remote key layout is otherwise unchanged:
+
+- immutable run history stays under `{session_prefix}/runs/{run_id}/`;
+- current state stays under `{session_prefix}/current/manifest.json`;
+- the final commit marker stays `{session_prefix}/current/run_id.txt`;
+- `current/run_id.txt` is still written last.
+
+## Compatibility Policy
+
+This is a hard cutover.
+
+After implementation:
+
+- `pipeline.archive` is rejected by strict YAML decoding.
+- `pipeline.archive.promote_artifacts` is rejected.
+- `pipeline.workspace.cleanup_after_archive` is rejected.
+- `pipeline.spool.delete_audio_after_archive` is rejected.
+- `narratio run-stage archive <session_id>` is an unknown stage.
+- manifests that record an `archive` stage are not migrated.
+- old archive/promotion metadata keys are not read as compatibility fallbacks.
+
+Existing remote objects are not moved or renamed. Remote layout remains stable;
+the rename changes configuration, stage names, status output, metadata, helper
+names, tests, examples, and documentation.
+
+## Implementation Stages
+
+### Stage 1: Public Schema and Stage Cutover
+
+Status: Planned
+
+Switch the public config and stage contract to publish terminology.
+
+Implementation requirements:
+
+- Replace `pipeline.archive` with `pipeline.publish`.
+- Replace `archive.promote_artifacts` with `publish.outputs`.
+- Keep output rule fields:
+  - `source`
+  - `dest`
+  - `required`
+- Replace `pipeline.archive.locks` with `pipeline.publish.locks`.
+- Rename post-publish cleanup fields:
+  - `pipeline.workspace.cleanup_after_publish`
+  - `pipeline.spool.delete_audio_after_publish`
+- Rename the registered stage from `archive` to `publish`.
+- Update stage order so `publish` runs after `analyze` and before `notify`.
+- Update top-level `narratio publish` to target stage `publish`.
+- Keep `run-stage --artifacts <names> publish` support.
+- Reject `run-stage --artifacts <names>` for stages other than `analyze` and
+  `publish`.
+- Preserve the remote commit ordering and storage adapter boundaries.
+
+Acceptance criteria:
+
+- `narratio run-stage publish <session_id>` executes the publish stage.
+- `narratio publish <session_id>` force-runs the publish stage.
+- `narratio run-stage archive <session_id>` fails clearly as an unknown stage.
+- Old archive config fields fail strict decoding.
+- New publish config fields load, default, and validate.
+
+### Stage 2: Runtime Terminology and Metadata Cutover
+
+Status: Planned
+
+Rename implementation concepts and runtime output to publish terminology.
+
+Implementation requirements:
+
+- Rename archive/promotion config and runtime types conceptually to
+  publish/output terms.
+- Rename the remote key helper intent from promoted artifact to published
+  output while keeping generated keys unchanged.
+- Change helper output:
+  - `Promoted:` becomes `Published:`
+  - `remote=promoted` becomes `remote=published`
+  - lock output uses `published` / `not-published`
+- Rename publish-stage metadata, including:
+  - `promoted_paths` to `published_paths`
+  - `promoted_files_uploaded` to `published_files_uploaded`
+  - `skipped_optional_promotions` to `skipped_optional_outputs`
+  - `skipped_unselected_promotions` to `skipped_unselected_outputs`
+  - `locked_promotion_count` to `locked_output_count`
+  - `locked_promotions` to `locked_outputs`
+- Update previous-cache and restore logic to use the `publish` stage and
+  `published_paths` metadata only.
+- Keep run-local stage output materialization separate from remote publish
+  terminology. If local helper names are confusing, rename them to
+  materialization-oriented names rather than publish names.
+
+Acceptance criteria:
+
+- Status and artifact helper output use `Published:` and `remote=published`.
+- Publish metadata contains only publish/output terminology.
+- Previous-cache and restore behavior works with publish metadata and does not
+  depend on old archive metadata.
+- Storage adapters still receive explicit keys and no AWS SDK details leak into
+  app or stage logic.
+
+### Stage 3: Documentation, Examples, and Final Cleanup
+
+Status: Planned
+
+Update implemented-behavior docs and remove stale public terminology after the
+runtime cutover lands.
+
+Implementation requirements:
+
+- Update current-behavior docs:
+  - `docs/config.md`
+  - `docs/cli.md`
+  - `docs/operations.md`
+  - `docs/troubleshooting.md`
+  - `docs/architecture.md`
+  - relevant files under `docs/internal/`
+- Rename `docs/internal/stage-archive.md` to
+  `docs/internal/stage-publish.md`.
+- Update internal documentation links and references.
+- Update examples to use:
+  - `publish.outputs`
+  - `publish.locks`
+  - `cleanup_after_publish`
+  - `delete_audio_after_publish`
+- Update tests and final searches so old terminology remains only in this
+  roadmap as historical context.
+
+Acceptance criteria:
+
+- Maintained examples load and validate.
+- Current-behavior docs describe only implemented publish terminology.
+- Internal docs describe run history, published outputs, locks, and current
+  commit ordering clearly.
+- Old user-facing archive/promote wording is removed except where discussing
+  historical behavior in this roadmap.
+
+## Test Guidance
+
+Focused tests:
+
+- `go test ./internal/config -v`
+- `go test ./internal/app -v`
+- `go test ./internal/stage -v`
+- `go test ./internal/artifacts -v`
+
+Full validation:
+
+- `go test ./...`
+
+Config tests to add or update:
+
+- `publish.outputs` defaults and validates.
+- `publish.outputs[].dest` derives from the artifact registry when omitted.
+- `publish.locks` validates with the same source rules as publish outputs.
+- old `archive` fails strict decode.
+- old `promote_artifacts` fails strict decode.
+- old cleanup fields fail strict decode.
+
+App and stage tests to add or update:
+
+- stage order uses `publish` before `notify`.
+- `run-stage publish` succeeds.
+- `run-stage archive` fails clearly.
+- `narratio publish` force-runs the `publish` stage.
+- `--artifacts` is accepted for `run-stage publish`.
+- `--artifacts` error text names `analyze` and `publish`.
+- status and artifact list output show `Published:` and `remote=published`.
+- lock output says `published` or `not-published`.
+- previous-cache and restore use `publish` stage metadata.
+
+Final searches:
+
+- Config/stage names:
+  - `pipeline.archive`
+  - `archive:`
+  - `promote_artifacts`
+  - `cleanup_after_archive`
+  - `delete_audio_after_archive`
+- User-facing output:
+  - `Promoted:`
+  - `remote=promoted`
+  - `not-promoted`
+- Runtime symbols and metadata:
+  - `ArchiveConfig`
+  - `ArchivePromotionRule`
+  - `S3PromotedArtifactKey`
+  - `promoted_paths`
+  - `promoted_files_uploaded`
+  - `locked_promotions`
+
+Expected remaining matches should be limited to this roadmap and narrowly
+justified historical references until the roadmap is fully retired.
+
+## Architecture Guardrails
+
+- Keep Narratio explicit and stage-driven.
+- Do not introduce a generic workflow or DAG abstraction.
+- Keep strict YAML decoding.
+- Keep remote path construction centralized.
+- Keep storage details behind `storage.ObjectStore`.
+- Keep AWS SDK types inside storage adapters.
+- Preserve manifest-driven resume and restore behavior.
+- Preserve current-state commit ordering with `current/run_id.txt` written
+  last.
+- Keep raw secrets out of configs, manifests, logs, generated configs, and
+  publish metadata.
+- Keep planned behavior only in this roadmap until implementation lands.
+
+## Assumptions
+
+- This is a breaking public/config/stage contract change.
+- No compatibility aliases are retained.
+- No migration logic is needed for in-progress local manifests.
+- No migration logic is needed for old remote manifests.
+- Existing remote objects are not moved or renamed.
+- `publish` means uploading run history, writing configured published outputs,
+  and committing current state.
+- `run history` is the preferred term for immutable per-run records under
+  `runs/<run_id>/`.
+- `archive` remains acceptable only as a generic English concept in historical
+  roadmap context, not as a public Narratio command, config field, stage name,
+  or metadata term after implementation.

+# Roadmap: Transcript Artifact Naming
+
+Status: Implemented
+
+## Problem
+
+Narratio's built-in transcript artifact names and canonical paths currently mix
+operator-facing artifact meaning with historical stage and tool terminology:
+
+- `narratio.transcript.merged` maps to `transcripts/merged.json`.
+- `narratio.transcript.polished` maps to `transcripts/processed.json`.
+- `narratio.transcript.full` maps to `transcripts/normalized.json`.
+- `narratio.transcript.trimmed` maps to `transcripts/trimmed.json`.
+
+This makes the public artifact surface harder to reason about. Operators see
+`full`, `normalized`, `processed`, `polished`, `merged`, and `trimmed` used in
+different places for the same transcript lineage.
+
+The transcript source IDs, canonical paths, and manifest output kinds should
+use one vocabulary based on each transcript's role in the session artifact
+model.
+
+## Target Model
+
+Built-in transcript artifacts should use these public source IDs, canonical
+paths, and manifest output kinds:
+
+| Source ID | Canonical path | Output kind | Meaning |
+| --- | --- | --- | --- |
+| `narratio.transcript.base` | `transcripts/base.json` | `transcript_base` | First unified transcript produced by merging per-speaker raw transcripts. |
+| `narratio.transcript.polished` | `transcripts/polished.json` | `transcript_polished` | Audita-polished transcript. |
+| `narratio.transcript.final` | `transcripts/final.json` | `transcript_final` | Full final transcript after normalization. |
+| `narratio.transcript.final_trimmed` | `transcripts/final.trimmed.json` | `transcript_final_trimmed` | Trimmed version of the final transcript. |
+
+Stage names remain process-oriented and unchanged:
+
+- `merge`
+- `polish`
+- `normalize`
+- `trim`
+
+Downstream adapter contracts also remain process-oriented. The rename changes
+Narratio's artifact model, canonical paths, config examples, archive promotion
+sources, lock sources, status output, and documentation. It should not rename
+the stages themselves or move external integration details into stage logic.
+
+## Compatibility Policy
+
+This is a hard cutover.
+
+After implementation, these old source IDs should be rejected:
+
+- `narratio.transcript.merged`
+- `narratio.transcript.full`
+- `narratio.transcript.trimmed`
+
+These old canonical paths should not be compatibility fallbacks:
+
+- `transcripts/merged.json`
+- `transcripts/processed.json`
+- `transcripts/normalized.json`
+- `transcripts/trimmed.json`
+
+Existing remote archives are not migrated automatically. Operators who want
+new promoted keys for old sessions should republish those sessions after
+updating configuration.
+
+## Implementation Stages
+
+### Stage 1: Centralize Transcript Artifact Naming
+
+Status: Implemented
+
+Consolidate transcript artifact source IDs, canonical paths, and output kinds
+in the artifact/path layer before changing runtime behavior.
+
+Implementation requirements:
+
+- Add or consolidate constants/helpers for built-in transcript source IDs.
+- Add or consolidate constants/helpers for canonical transcript paths.
+- Add or consolidate constants/helpers for transcript manifest output kinds.
+- Keep source ID, path, and output-kind mappings in one registry or one
+  obviously shared artifact model.
+- Update artifact registry tests to prove the target mapping.
+- Avoid changing stage output behavior in this stage unless the implementation
+  is simpler and still reviewable.
+
+Acceptance criteria:
+
+- There is one clear source of truth for built-in transcript artifact names,
+  paths, and output kinds.
+- Tests prove the new target mapping in the artifact layer.
+- No generic workflow abstraction is introduced.
+
+### Stage 2: Rename Runtime Outputs and Defaults
+
+Status: Implemented
+
+Switch runtime behavior to the new transcript artifact model.
+
+Implementation requirements:
+
+- Update `merge` to write and record `transcripts/base.json` with
+  `transcript_base`.
+- Update `polish` to write and record `transcripts/polished.json` with
+  `transcript_polished`.
+- Update `normalize` to write and record `transcripts/final.json` with
+  `transcript_final`.
+- Update `trim` to write and record `transcripts/final.trimmed.json` with
+  `transcript_final_trimmed`.
+- Update normalize and trim defaults to:
+  - `pipeline.normalize.output_path: transcripts/final.json`
+  - `pipeline.trim.output_path: transcripts/final.trimmed.json`
+- Update built-in artifact resolution, archive promotion destination
+  derivation, archive locks, status output, artifact catalog output,
+  previous-cache resolution, restore planning, and restore execution to use
+  the new registry values.
+- Ensure old source IDs fail config validation.
+
+Acceptance criteria:
+
+- New runs produce the target canonical transcript files.
+- Manifest outputs use the target output kinds.
+- Archive promotion and lock validation accept new source IDs and reject old
+  source IDs.
+- Status and artifact listing display new source IDs.
+- Restore uses the new canonical paths and does not restore old transcript
+  paths as canonical outputs.
+
+### Stage 3: Update Tests, Examples, and Current Documentation
+
+Status: Implemented
+
+Update all implemented-behavior references after the runtime cutover lands.
+
+Implementation requirements:
+
+- Update examples to use `narratio.transcript.final_trimmed` and
+  `transcripts/final.trimmed.json` where trimmed final transcript is intended.
+- Update examples that refer to full final transcripts to use
+  `narratio.transcript.final` and `transcripts/final.json`.
+- Update `docs/config.md`, `docs/internal/artifacts.md`, stage docs,
+  CLI examples, operations examples, archive examples, lock examples, and
+  status/artifact-list examples.
+- Add strict validation tests proving old source IDs are rejected.
+- Mark roadmap stages implemented only after code, tests, examples, and
+  current-behavior docs agree.
+
+Acceptance criteria:
+
+- Maintained examples load and validate.
+- Current-behavior docs describe only implemented new names.
+- Old names remain only in this roadmap as historical/planning context until
+  this roadmap is retired or archived.
+
+## Test Guidance
+
+Run focused tests while implementing:
+
+- `go test ./internal/artifacts -v`
+- `go test ./internal/config -v`
+- `go test ./internal/stage -v`
+- `go test ./internal/app -v`
+
+Run full validation before finishing:
+
+- `go test ./...`
+
+Run final searches:
+
+- Old source IDs:
+  - `narratio.transcript.merged`
+  - `narratio.transcript.full`
+  - `narratio.transcript.trimmed`
+- Old paths:
+  - `transcripts/merged.json`
+  - `transcripts/processed.json`
+  - `transcripts/normalized.json`
+  - `transcripts/trimmed.json`
+- Old output kinds:
+  - `transcript_merged`
+  - `transcript_processed`
+  - `transcript_normalized`
+  - `transcript_trimmed`
+
+Expected remaining matches should be limited to this roadmap's
+historical/planning references until the roadmap is fully completed.
+
+## Architecture Guardrails
+
+- Keep Narratio explicit and stage-driven; do not introduce a generic workflow
+  or DAG abstraction.
+- Keep path and artifact naming in centralized helpers rather than scattered
+  string concatenation.
+- Preserve manifest-driven resume behavior.
+- Keep storage details behind storage adapters.
+- Do not move Seriatim, Audita, or Scriptorium command details out of their
+  adapter boundaries.
+- Keep current-behavior documentation in sync only after implementation lands;
+  planned behavior belongs in this roadmap until then.
+
+## Assumptions
+
+- The cutover is intentionally not backward-compatible.
+- Existing remote archive objects are not renamed or migrated automatically.
+- Stage names and downstream adapter request field names remain unchanged.
+- The term `base` is preferred over `merged` for the first unified transcript.
+- The term `final` is preferred over `full` or `normalized` for the full final
+  transcript.
+- The trimmed final path is `transcripts/final.trimmed.json`.

+# Troubleshooting
+
+## Purpose
+Canonical operator troubleshooting guide for recurring implemented Narratio failures.
+
+## Config file discovery failure
+
+Symptom:
+- `run`, `resume`, `run-stage`, `session plan`, or `session restore` fails with config/session not found.
+
+Likely Cause:
+- `pipeline.yml` or `session.yml` is missing from system discovery paths.
+- the selected campaign ID does not exist under `pipeline.campaigns.root`.
+- a local working-directory config file was not passed explicitly.
+
+Diagnostics:
+
+```bash
+ls -l /usr/local/etc/narratio/pipeline.yml /etc/narratio/pipeline.yml
+ls -l /usr/local/etc/narratio/session.yml /etc/narratio/session.yml
+```
+
+Safe Fix:
+- pass explicit `--config`, `--campaign <id>`, `--campaign-file <path>`, and `--session` as appropriate.
+- or place files in documented discovery paths and set `pipeline.campaigns.default_campaign_id`.
+
+Links:
+- [docs/config.md](./config.md)
+- [docs/cli.md](./cli.md)
+
+## Templated session file rejected
+
+Symptom:
+- load fails with a message that `session.yml must be concrete`.
+
+Likely Cause:
+- a template authoring file such as `session.template.yml` was passed to `--session` or uploaded as remote `session.yml`.
+- `session.yml` still contains `{{ ... }}` placeholders.
+
+Diagnostics:
+
+```bash
+narratio session plan 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session ./session.yml
+```
+
+Safe Fix:
+- generate concrete YAML with `narratio session init`.
+- pass the generated concrete `session.yml` to downstream commands or upload it through `session init --remote`.
+
+Links:
+- [docs/config.md](./config.md)
+
+## Strict YAML decode or validation failure
+
+Symptom:
+- config load fails with unknown field or validation error.
+
+Likely Cause:
+- typo/stale field name.
+- missing required fields or invalid constraints.
+
+Diagnostics:
+
+```bash
+narratio session plan 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml
+```
+
+Safe Fix:
+- align fields/values to canonical config reference and examples.
+
+Links:
+- [docs/config.md](./config.md)
+- [examples/](../examples/)
+
+## `--artifacts` selection failure
+
+Symptom:
+- `run`/`resume`/`run-stage` fails with invalid or unknown artifact selection.
+
+Likely Cause:
+- `--artifacts` contains blank names or unknown artifact keys.
+- `pipeline.scriptorium.artifacts` missing while using `--artifacts`.
+
+Diagnostics:
+
+```bash
+narratio run 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml --artifacts player_handout
+```
+
+Safe Fix:
+- use configured artifact keys only.
+- ensure `pipeline.scriptorium.artifacts` is defined.
+
+Links:
+- [docs/cli.md](./cli.md)
+- [docs/config.md](./config.md)
+
+## `run-stage --artifacts` on unsupported stage
+
+Symptom:
+- `run-stage` fails because `--artifacts` is only supported for `analyze` and `archive`.
+
+Likely Cause:
+- `--artifacts` was used with a stage other than `analyze` or `archive`.
+
+Diagnostics:
+
+```bash
+narratio run-stage polish 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml --artifacts session_recap
+```
+
+Safe Fix:
+- use `--artifacts` only with `run-stage analyze ...` or `run-stage archive ...`.
+
+Links:
+- [docs/cli.md](./cli.md)
+
+## Configured artifact dependency/input validation failure
+
+Symptom:
+- config validation fails for `depends_on`, `narratio.artifact.<name>` source, or artifact output path.
+
+Likely Cause:
+- `narratio.artifact.<name>` source missing matching `depends_on` key.
+- dependency references unknown artifact key.
+- dependency self-reference or enabled dependency cycle.
+- artifact output path missing/invalid/outside `artifacts/` root.
+
+Diagnostics:
+
+```bash
+narratio session plan 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml
+```
+
+Safe Fix:
+- ensure artifact-to-artifact inputs have explicit `depends_on` entries using artifact keys.
+- ensure referenced artifacts exist and define valid `output_path` values.
+- keep output paths relative and under `artifacts/`.
+
+Links:
+- [docs/config.md](./config.md)
+- [docs/internal/stage-analyze.md](./internal/stage-analyze.md)
+
+## Required configured artifact input unavailable at analyze time
+
+Symptom:
+- analyze fails because configured input source is unavailable.
+
+Likely Cause:
+- required upstream configured artifact was not selected/executed this run.
+- non-executable dependency output file is missing or invalid on disk.
+
+Diagnostics:
+
+```bash
+narratio session status 2026-04-04
+narratio run-stage analyze 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml --artifacts player_handout
+```
+
+Safe Fix:
+- run analyze with needed artifacts selected.
+- or ensure dependency output file exists at configured path and is valid.
+
+Links:
+- [docs/operations.md](./operations.md)
+- [docs/config.md](./config.md)
+
+## Manifest/status path failure
+
+Symptom:
+- `session status` fails because config/session state is missing, unreadable, or invalid.
+
+Likely Cause:
+- wrong session ID.
+- wrong config/campaign/session file selected.
+- manifest removed after cleanup.
+
+Diagnostics:
+
+```bash
+narratio session status 2026-04-04
+```
+
+Safe Fix:
+- use the same session ID and config files that will be used for `run`, `resume`, or `run-stage`.
+
+Links:
+- [docs/cli.md](./cli.md)
+- [docs/operations.md](./operations.md)
+
+## Session lock conflict (`.lock`)
+
+Symptom:
+- `run`, `resume`, `run-stage`, or `session restore` fails with lock conflict for session workdir.
+
+Likely Cause:
+- another Narratio process is running same session.
+- stale lock from interrupted prior run.
+
+Diagnostics:
+
+```bash
+ls -l {workspace.root}/work/{campaign}/{session_id}/.lock
+cat {workspace.root}/work/{campaign}/{session_id}/.lock
+ps aux | grep narratio
+```
+
+Safe Fix:
+- wait for active process to finish.
+- if no process is active, remove only stale session `.lock` file.
+
+Links:
+- [docs/operations.md](./operations.md)
+- [docs/internal/workspace.md](./internal/workspace.md)
+
+## Restore remote current pointer or manifest missing
+
+Symptom:
+- `session restore` fails with remote current pointer or current manifest errors.
+
+Likely Cause:
+- `current/run_id.txt` was never published.
+- `current/manifest.json` is missing for the session prefix.
+- archive commit did not complete.
+
+Diagnostics:
+
+```bash
+narratio session restore 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml --dry-run
+```
+
+Safe Fix:
+- verify archive stage succeeded for the target session.
+- rerun/archive from a healthy source workspace so current pointers are published.
+
+Links:
+- [docs/operations.md](./operations.md)
+- [docs/internal/stage-archive.md](./internal/stage-archive.md)
+
+## Restore manifest identity mismatch
+
+Symptom:
+- `session restore` fails because remote manifest session or campaign does not match requested values.
+
+Likely Cause:
+- wrong positional session ID or wrong session config selected.
+- archive prefix points to a different campaign/session.
+
+Diagnostics:
+
+```bash
+narratio session restore 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml --dry-run
+```
+
+Safe Fix:
+- use the correct session config and positional session ID.
+- verify campaign/session identity in local config before restore.
+
+Links:
+- [docs/config.md](./config.md)
+- [docs/operations.md](./operations.md)
+
+## Restore conflict without `--force`
+
+Symptom:
+- `session restore` fails with `restore conflict` and conflict counts.
+
+Likely Cause:
+- local durable file differs from remote file for one or more planned restore paths.
+
+Diagnostics:
+
+```bash
+narratio session restore 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml --dry-run
+```
+
+Safe Fix:
+- review planned conflicts.
+- rerun with `--force` only when remote state should overwrite local state.
+
+Links:
+- [docs/cli.md](./cli.md)
+- [docs/operations.md](./operations.md)
+
+## Restore report expectations
+
+Symptom:
+- operator expects restore report file but does not find one.
+
+Likely Cause:
+- restore was executed in `--dry-run` mode.
+- restore failed before report persistence path (for example lock acquisition failure).
+
+Diagnostics:
+
+```bash
+ls -l {workspace.root}/work/{campaign}/{session_id}/reports/restore-latest.json
+```
+
+Safe Fix:
+- run non-dry-run restore for durable report output.
+- resolve lock or early preflight failures and retry.
+
+Links:
+- [docs/operations.md](./operations.md)
+
+## Secrets env-dir or credential-env failure
+
+Symptom:
+- startup fails loading secrets directory, or stage fails due to missing credential env vars.
+
+Likely Cause:
+- invalid `pipeline.secrets.env_dir` path/permissions.
+- required credential env var unset/empty.
+
+Diagnostics:
+
+```bash
+ls -la /path/to/secrets_dir
+env | grep -E 'AUDITA|OBJECT_STORAGE|AWS|SCRIPTORIUM'
+```
+
+Safe Fix:
+- fix secrets directory and credential env vars.
+- keep secret values out of YAML.
+
+Links:
+- [docs/config.md](./config.md)
+
+## S3-audio prepare failure
+
+Symptom:
+- `prepare` fails in S3 mode (listing/downloading/no audio/backend error).
+
+Likely Cause:
+- wrong `session.inputs.audio_s3.prefix`.
+- no `.flac` files at resolved prefix.
+- invalid/missing object-store credentials or backend config.
+- mixed local+S3 audio input config.
+
+Diagnostics:
+
+```bash
+narratio run-stage prepare 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml
+```
+
+Safe Fix:
+- configure exactly one audio source mode.
+- verify `.flac` files and storage access.
+
+Links:
+- [docs/config.md](./config.md)
+- [docs/operations.md](./operations.md)
+
+## Archive promotion/current-pointer failure
+
+Symptom:
+- archive fails on required promotion source missing or pointer write failure.
+
+Likely Cause:
+- required promoted file absent (including analyze outputs not generated for this run).
+- storage upload failed before `current/run_id.txt` commit marker write.
+
+Diagnostics:
+
+```bash
+narratio session status 2026-04-04
+narratio run-stage archive 2026-04-04 --config /path/to/pipeline.yml --campaign-file /path/to/campaign.yml --session /path/to/session.yml
+```
+
+Safe Fix:
+- rerun or resume upstream stages to generate required files.
+- adjust promotion `source`/`dest` rules to match artifacts that must exist.
+- retry after storage issue is resolved.
