 # 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:
-
-- `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`
-
-Session config lookup for CLI commands:
-
-- if `--session <path>` is provided, Narratio uses that path
-- if `--session` is omitted, Narratio searches in this order:
-  - `./session.yml`
-  - `/usr/local/etc/narratio/session.yml`
-  - `/etc/narratio/session.yml`
-
-Session template support:
-
-- Narratio renders `session.yml` templates before strict YAML decode.
-- `--session-id <value>` provides the `session_id` template variable.
-- Supported placeholder forms:
-  - `{{session_id}}`
-  - `{{ session_id }}`
-- unresolved template placeholders fail with a clear error.
-- strict YAML validation still runs after rendering.
-- concrete `session.yml` files without templates remain fully supported.
-
-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.
-
-Maintainer note: application defaults are centralized in [`internal/config/defaults.go`](internal/config/defaults.go).
-
-## Storage And Archive Foundations
-
-Narratio now includes configuration and path-model foundations for archive support, plus implemented prepare-stage S3 audio input.
-
-Implemented foundations:
-
-- `pipeline.storage.s3` config shape (`bucket`, `root_prefix`, `region`, `endpoint`, `force_path_style`, `access_key_id_env`, `secret_access_key_env`)
-- `pipeline.spool` config shape (`root`, `delete_audio_after_archive`)
-- `pipeline.archive` config shape (`enabled`, `upload_run`, `promote_artifacts`)
-- promotion-rule validation (`from`/`to` required, relative-only paths, traversal rejected)
-- `session.campaign` requirement for campaign-aware path construction
-- optional `session.inputs.audio_s3.prefix` modeling and prepare-stage S3 audio download
-- run ID generation and S3/local path helper foundations
-- manifest run/path identity fields
-
-Current defaults:
-
-- `pipeline.storage.s3.root_prefix`: `dnd`
-- `pipeline.storage.s3.access_key_id_env`: `OBJECT_STORAGE_KEY_ID`
-- `pipeline.storage.s3.secret_access_key_env`: `OBJECT_STORAGE_KEY`
-- `pipeline.workspace.cleanup_after_archive`: `false`
-- `pipeline.spool.root`: `/var/spool/narratio`
-- `pipeline.spool.delete_audio_after_archive`: `false`
-- `pipeline.archive.enabled`: `true`
-- `pipeline.archive.upload_run`: `true`
-- default `pipeline.archive.promote_artifacts`:
-  - `transcripts/trimmed.json` -> `transcripts/trimmed.json` (`required: true`)
-  - `artifacts/session_recap.md` -> `artifacts/session_recap.md` (`required: true`)
-
-Current boundaries:
-
-- local development audio (`audio_dir` / `audio_files`) still works
-- `audio_dir`/`audio_files` and `audio_s3` are mutually exclusive
-- real S3-compatible backend now exists in the storage adapter package
-- storage backend tests use fake storage and do not require live S3
-- archive uploads successful run records under `runs/{run_id}/`
-- archive does not upload local audio by default
-- archive uploads promoted outputs to session-level keys using `archive.promote_artifacts`
-- archive uploads `current/manifest.json`
-- archive uploads `current/run_id.txt` last as the effective commit marker
-- required missing promotions fail archive
-- optional missing promotions are skipped and recorded
-- cleanup remains conservative and opt-in:
-  - `pipeline.spool.delete_audio_after_archive: true` removes only the run-scoped spool audio directory after successful archive commit
-  - `pipeline.workspace.cleanup_after_archive: true` removes only the run-scoped local workdir after successful archive commit
-  - cleanup executes only after all selected stages for the command invocation succeed
-  - cleanup does not run for failed, incomplete, skipped, or unarchived runs
-- local development `audio_dir`/`audio_files` source inputs are never deleted by spool cleanup
-- S3 credentials are resolved from configured env-var names when both are present; if either is missing, Narratio falls back to the AWS SDK default credential chain
-
-S3 input details and current boundaries are documented in [docs/s3-audio-input.md](docs/s3-audio-input.md).
-
-## Remote Storage Backend
-
-Narratio includes an object-store backend layer for future prepare/archive work:
-
-- `List(ctx, prefix)`
-- `Download(ctx, key, localPath)`
-- `Upload(ctx, localPath, key, opts)`
-- `Exists(ctx, key)`
-
-Implemented backends:
-
-- fake storage backend for deterministic tests
-- S3-compatible backend built from `pipeline.storage.s3`
-
-Key invariant:
-
-- callers pass full bucket-relative object keys
-- storage backends do not prepend `root_prefix` and do not infer session/campaign paths
-
-Current boundary:
-
-- `prepare` uses `List` + `Download` through the backend when `session.inputs.audio_s3` is configured
-- `archive` uses `Upload` through the backend for successful run-record uploads
-- `archive` also uses `Upload` for promotion writes and current pointers
-- no failed or incomplete runs are uploaded
-- local audio is not re-uploaded by default
-
-Archive run-upload details and boundaries are documented in [docs/archive-storage.md](docs/archive-storage.md).
-
-## 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
-
-## Seriatim Configuration
-
-`pipeline.seriatim` configures the Seriatim subprocess adapter used by `merge`, `normalize`, and `trim`.
-
-Minimal behavior:
-
-- `pipeline.seriatim` may be omitted entirely.
-- when omitted, Narratio defaults to:
-  - `binary: seriatim`
-  - `timeout: 10m`
-  - `output_schema: seriatim-intermediate`
-  - `coalesce_gap: 3.0`
-  - `report: true`
-
-Optional overrides in `pipeline.seriatim` continue to work, including explicit binary paths and advanced `env` tuning values.
-
-## Audita Configuration
-
-`pipeline.audita` configures the real Audita subprocess adapter used by `polish`.
-
-Minimal behavior:
-
-- `pipeline.audita` may be omitted entirely.
-- when omitted, Narratio defaults to:
-  - `binary: audita`
-  - `timeout: 3h`
-  - `report: true`
-
-Optional:
-
-- `llm_api_key_env` (when set, Narratio requires that env var and passes it to Audita as `AUDITA_LLM_API_KEY`)
-- `modules` override list (when empty/omitted, Narratio does not pass `--modules`)
-- `base_url` (when omitted, Narratio does not pass `--base-url`; Audita runtime defaults/config may apply)
-- `model` (when omitted, Narratio does not pass `--model`; Audita runtime defaults/config may apply)
-- `transcript_description`
-- `config_path`
-- `output_schema` (`bare-segments` or `audita-v1`)
-- `work_dir_retention` (`always`, `auto`, or `never`)
-- `total_llm_concurrency` (> 0 when provided)
-- `proposal_llm_concurrency` (> 0 when provided)
-- `validation_model`
-- `validation_llm_concurrency` (> 0 when provided)
-- `report` (defaults to `true`)
-
-Narratio passes only configured optional Audita flags. Omitted optional values are left to Audita runtime defaults/config.
-
-## 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` defaults to `scriptorium` 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:
-
-- preferred transcript artifact source IDs:
-  - `narratio.transcript.polished`
-  - `narratio.transcript.full`
-  - `narratio.transcript.trimmed`
-- backward-compatible aliases remain supported:
-  - `processed_transcript`
-  - `normalized_transcript`
-  - `trimmed_transcript`
-- session recap should use gameplay-only transcript input (`source: trimmed_transcript`)
-- Narratio resolves transcript inputs from the artifact resolver (manifest producer outputs first, then canonical session paths)
-- 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/pipeline.audita-overrides.yml`
-- `examples/session.minimal.yml`
-- `examples/session.template.yml`
-- `examples/speakers.yml`
-
-## Commands
-
-Run tests:
 
 ```bash
-go test ./...
+narratio run --session-id 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.

-
+- [CLI Reference](docs/cli.md)
-Run with a discoverable session template:

-Run full pipeline:
-
-```bash

-```
-
-Run analyze only:
-
-```bash
-go run ./cmd/narratio run-stage --config examples/pipeline.minimal.yml --session examples/session.minimal.yml analyze
-```
-
-Resume with a template session ID:
-
-```bash
-go run ./cmd/narratio resume --config examples/pipeline.minimal.yml --session examples/session.template.yml --session-id 2026-04-04
-```
-
-## 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
-- storage/archive configuration and validation foundations for:
-  - `pipeline.storage.s3`
-  - `pipeline.spool`
-  - `pipeline.archive` promotion rules
-  - `session.inputs.audio_s3`
-- run identity and path-model foundations:
-  - run ID generation (`YYYYMMDDTHHMMSSZ-xxxxxxxx`)
-  - S3 session/run/current key builders
-  - campaign/session/run local work/spool path helpers
-  - manifest run/path identity fields (`campaign`, `run_id`, local and S3 prefixes)
-- remote storage backend layer:
-  - narrow object-store interface (`List`, `Download`, `Upload`, `Exists`)
-  - fake storage backend for deterministic tests (no network dependency)
-  - S3-compatible backend using AWS SDK v2
-  - config-based object-store construction helper
-
-Still placeholder/future:
-
-- `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`
-- default values are centralized in `internal/config/defaults.go`
-
-CLI session config path resolution:
-
-- when `--session <path>` is provided, that path is used
-- when `--session` is omitted, Narratio searches defaults in order:
-  - `./session.yml`
-  - `/usr/local/etc/narratio/session.yml`
-  - `/etc/narratio/session.yml`
-
-Session template rendering:
-
-- session templates are rendered before strict YAML decode
-- `--session-id <value>` provides the `session_id` template variable
-- supported placeholders:
-  - `{{session_id}}`
-  - `{{ session_id }}`
-- unresolved placeholders fail clearly
-- strict `KnownFields(true)` YAML validation still applies after rendering
-- if rendered `session.session_id` conflicts with `--session-id`, load fails clearly
-
-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
-
-Storage and archive foundations:
-
-- `pipeline.storage.s3` is available for modeling S3 coordinates:
-  - `bucket`
-  - `root_prefix` (default `dnd`)
-  - `region`
-  - `endpoint`
-  - `force_path_style` (default `false`)
-  - `access_key_id_env` (default `OBJECT_STORAGE_KEY_ID`)
-  - `secret_access_key_env` (default `OBJECT_STORAGE_KEY`)
-- `pipeline.spool.root` defaults to `/var/spool/narratio`
-- `pipeline.workspace.cleanup_after_archive` defaults to `false`
-- `pipeline.spool.delete_audio_after_archive` defaults to `false`
-- `pipeline.archive` is optional and defaults to:
-  - `enabled: true`
-  - `upload_run: true`
-  - default `promote_artifacts`:
-    - `transcripts/trimmed.json`
-    - `artifacts/session_recap.md`
-- archive promotion rules enforce safe relative paths:
-  - `from` and `to` are required
-  - absolute paths are rejected
-  - traversal segments such as `..` are rejected
-
-Session input foundations:
-
-- `session.campaign` is required
-- local audio remains supported through `session.inputs.audio_dir` or `session.inputs.audio_files`
-- optional S3 audio input shape is `session.inputs.audio_s3.prefix`
-- `audio_dir`/`audio_files` and `audio_s3` are mutually exclusive
-- when `audio_s3` is configured, `prepare` lists and downloads `.flac` objects through the object-store backend
-
-Cross-config validation scope:
-
-- `pipeline.storage.s3.bucket` is required only when an S3-dependent feature is explicitly configured (for current foundations, that includes `session.inputs.audio_s3`, and archive upload intent when using `storage.backend: s3`)
-- no AWS credential values are stored in Narratio config; only env-var names are configured
-- when both configured credential env vars resolve to non-empty values, the S3 backend uses them as static credentials
-- when either configured credential value is missing, the S3 backend falls back to the AWS SDK default credential chain
-
-Remote object-store backend scope:
-
-- remote storage APIs are isolated to `internal/adapters/storage`
-- AWS SDK types remain contained within the S3 backend implementation package
-- S3 key/session path semantics remain outside the backend, with this invariant:
-  - callers pass full bucket-relative object keys
-  - backend methods do not prepend `root_prefix` or infer campaign/session/run paths
-- `prepare` now uses object-store `List` and `Download` for S3 audio input
-- `archive` now uses object-store `Upload` for successful run-record upload under the run prefix
-- `archive` now uses object-store `Upload` for promoted outputs and current pointers
-
-Prepare S3 audio behavior (implemented):
-
-- compute session prefix as `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/`
-- resolve `session.inputs.audio_s3.prefix` under that session prefix
-- list objects under the computed audio prefix and filter `.flac` keys
-- fail clearly when no `.flac` objects are found
-- download selected objects to spool audio path:
-  - `{spool.root}/{campaign}/{session_id}/{run_id}/audio/`
-- materialize audio files into workdir audio path:
-  - `{workspace.root}/work/{campaign}/{session_id}/{run_id}/audio/`
-- record S3 provenance in manifest input records (bucket/key/metadata/local paths/checksum)
-- no AWS SDK types are used in stage code; storage implementation details stay in storage adapter packages
-
-Archive publishing behavior (implemented):
-
-- `archive` verifies prerequisite stage success before upload:
-  - `prepare`, `transcribe`, `merge`, `polish`, `normalize`, `trim`, `analyze`
-- only successful/completed runs are uploaded
-- uploaded run record destination is:
-  - `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/runs/{run_id}/`
-- uploaded existing local paths include:
-  - `inputs/`, `transcripts/`, `artifacts/`, optional `reports/`, `config/`, `logs/`, and `manifest.json`
-- local `audio/` is intentionally excluded from upload by default
-- file upload order is deterministic (sorted relative paths)
-- `archive.enabled: false` and `archive.upload_run: false` skip upload cleanly
-- stage metadata records non-secret upload context:
-  - run upload details, promoted output details, current manifest key, current pointer key
-  - no secrets, transcript contents, prompt contents, or environment dumps
-- promotion rules:
-  - `from` resolves from local workdir
-  - `to` resolves under session-level S3 root
-  - missing required source fails archive
-  - missing optional source is skipped and recorded
-- default promoted outputs:
-  - `transcripts/trimmed.json`
-  - `artifacts/session_recap.md`
-- current pointers:
-  - `current/manifest.json` uploaded after run upload and promotions
-  - `current/run_id.txt` uploaded last with `{run_id}\n`
-  - `current/run_id.txt` is the effective commit marker
-- if promotion or current-manifest upload fails, archive returns failure and does not write `current/run_id.txt`
-- failed/incomplete runs remain local and are not uploaded
-- post-archive local cleanup (implemented, opt-in):
-  - cleanup runs only after archive succeeded and wrote `current/run_id.txt`
-  - cleanup is executed after all selected stages in the command invocation succeed (for example, a later `notify` failure leaves local files intact)
-  - `pipeline.spool.delete_audio_after_archive: true` removes only `{spool.root}/{campaign}/{session_id}/{run_id}/audio/`
-  - `pipeline.workspace.cleanup_after_archive: true` removes only `{workspace.root}/work/{campaign}/{session_id}/{run_id}/`
-  - cleanup does not run when archive is skipped/disabled/fails or when run upload is disabled
-  - local development `audio_dir`/`audio_files` inputs are never removed by spool cleanup
-
-`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.
-
-`pipeline.audita` drives the real Audita subprocess adapter for the `polish` stage.
-
-Audita defaulted fields:
-
-- `binary` defaults to `audita`

-- `report` defaults to `true`
-
-Audita optional fields:
-

-
-Narratio passes only configured optional Audita flags; omitted optional values defer to Audita runtime defaults/config.
-
-Seriatim defaults:
-
-- `pipeline.seriatim` may be omitted
-- `binary` defaults to `seriatim`
-- `timeout` defaults to `10m`
-- `output_schema` defaults to `seriatim-intermediate`

-
-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.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` defaults to `scriptorium` when omitted
-- `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
-

-- `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 --session-id 2026-04-04
+```
+
+This command uses default discovery for `pipeline.yml` and `session.yml`; both files must be discoverable unless you pass explicit `--config` and `--session` paths.
+
+## Command Overview
+
+Implemented commands:
+
+- `run`: execute pipeline stages and persist manifest state.
+- `plan`: validate config, prepare workspace layout, and print stage run/skip decisions.
+- `resume`: continue from first non-succeeded stage unless forced.
+- `status`: read and print stage statuses from an existing manifest.
+- `run-stage`: execute exactly one stage.
+- `restore`: restore durable local session state from the committed remote archive state.
+
+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).

+- Restore durable session state (`manifest.json`, `transcripts/**`, `artifacts/**`, and optional `audio/**`) from the committed remote archive current state.
+
+Syntax:
+
+```bash
+narratio restore [--config <pipeline.yml>] [--session <session.yml>] [--session-id <id>] [--dry-run] [--force] [--include-audio]
+```
+
+Success output (dry-run):
+- `Restore plan for <campaign>/<session_id>`
+- `Remote run: <run_id>`
+- `Would download: <n>`
+- `Would skip unchanged: <n>`
+- `Conflicts: <n>`
+
+Success output (non-dry-run):
+- `Restored session archive for <campaign>/<session_id>`
+- `Remote run: <run_id>`
+- `Downloaded: <n>`
+- `Skipped unchanged: <n>`
+- `Conflicts: <n>`
+
+Common failure cases:
+- storage backend is not configured.
+- remote `current/run_id.txt` missing/empty.
+- remote `current/manifest.json` missing or invalid.
+- remote manifest session/campaign mismatch.
+- local conflicts without `--force`.
+- session lock conflict.
+
+## Common Workflows
+
+Default-discovery run:
+
+```bash
+narratio run --session-id 2026-04-04
+```
+
+Run only selected analyze artifacts:
+
+```bash
+narratio run --session-id 2026-04-04 --artifacts session_recap,player_handout
+```
+
+Resume with selected analyze artifacts:
+
+```bash
+narratio resume --session-id 2026-04-04 --artifacts player_handout
+```
+
+Run only analyze stage with selected artifacts:
+
+```bash
+narratio run-stage --session-id 2026-04-04 --artifacts player_handout analyze
+```
+
+Preview restore actions without writes:
+
+```bash
+narratio restore --session-id 2026-04-04 --dry-run
+```
+
+Restore and then force analyze:
+
+```bash
+narratio restore --session-id 2026-04-04
+narratio run-stage --session-id 2026-04-04 --force analyze
+```
+
+## Diagnostic / Recovery Commands
+
+Inspect stage status:
+
+```bash
+narratio status --manifest <manifest.json>
+```
+
+Get manifest path from previous output:
+- `run`, `resume`, and `run-stage` print `manifest=<path>` on success.
+
+## `--artifacts` and `--force`
+
+- `--artifacts` filters which configured artifacts are executable when analyze runs.
+- `--artifacts` does not imply `--force`.
+- if analyze is already `succeeded` and `--force` is not set, runner-level skip still applies.

+# Configuration
+
+## 1. Overview
+
+Narratio loads two YAML files:
+
+- `pipeline.yml`: pipeline-level runtime configuration.
+- `session.yml`: per-session metadata and input selection.
+
+These commands load and validate both files before running:
+
+- `narratio run`
+- `narratio plan`
+- `narratio resume`
+- `narratio run-stage`
+- `narratio restore`
+
+Behavior:
+
+- strict YAML decode is enabled (`KnownFields(true)`): unknown fields fail.
+- session templates render before session YAML decode.
+- defaults are applied for optional pipeline fields.
+- validation enforces required fields, value formats, and cross-field constraints.
+
+## 2. Config file discovery
+
+Pipeline config lookup for `run`, `plan`, `resume`, `run-stage`, and `restore`:
+
+- 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.
+
+## 3. Session file discovery and templating
+
+Session config lookup for `run`, `plan`, `resume`, `run-stage`, and `restore`:
+
+- if `--session <path>` is provided, that path is used.
+- if omitted, Narratio searches in order:
+  1. `./session.yml`
+  2. `/usr/local/etc/narratio/session.yml`
+  3. `/etc/narratio/session.yml`
+- first existing file wins.
+
+Template behavior:
+
+- supported placeholders:
+  - `{{session_id}}`
+  - `{{ session_id }}`
+- `--session-id <value>` supplies the placeholder value.
+- unresolved placeholders fail load.
+- if rendered `session_id` mismatches `--session-id`, load fails.
+
+## 4. Minimal pipeline config
+
+```yaml
+whisperx:
+  transcribe_url: "https://transcription.example.com/transcribe"
+```
+
+Why this is sufficient:
+
+- `whisperx.transcribe_url` is required.
+- `workspace.root` defaults to `/var/lib/narratio`.
+- optional sections (`seriatim`, `audita`, `archive`, `scriptorium`, `trim`, `normalize`, etc.) receive defaults or stay inactive.
+
+## 5. Minimal session template
+
+```yaml
+session_id: "{{ session_id }}"
+campaign: sample-campaign
+inputs:
+  audio_dir: ./audio
+  speakers_file: ./examples/speakers.yml
+  autocorrect_file: ./examples/autocorrect.yml
+  glossary_file: ./examples/glossary.yml
+```
+
+Usage:
+
+```bash
+narratio run --config /path/to/pipeline.yml --session ./session.yml --session-id 2026-05-03
+```
+
+## 6. Production-oriented config
+
+```yaml
+workspace:
+  root: /var/lib/narratio/workspace
+  cleanup_after_archive: true
+
+storage:
+  backend: s3
+  s3:
+    bucket: my-dnd-archive
+    root_prefix: dnd
+    region: us-east-1
+    access_key_id_env: OBJECT_STORAGE_KEY_ID
+    secret_access_key_env: OBJECT_STORAGE_KEY
+
+spool:
+  root: /var/spool/narratio
+  delete_audio_after_archive: true
+
+archive:
+  enabled: true
+  upload_run: true
+  promote_artifacts:
+    - source: narratio.transcript.trimmed
+      dest: transcripts/trimmed.json
+      required: true
+    - source: narratio.artifact.session_recap
+      dest: artifacts/session_recap.md
+      required: true
+
+whisperx:
+  transcribe_url: "https://transcription.example.com/transcribe"
+
+scriptorium:
+  artifacts:
+    session_recap:
+      enabled: true
+      prompt_id: dnd.session_recap
+      output_path: artifacts/session_recap.md
+      inputs:
+        transcript:
+          source: narratio.transcript.trimmed
+          required: true
+```
+
+Operational notes:
+
+- archive promotion is explicit and source-based via `archive.promote_artifacts`.
+- `source` is required; `dest` is optional and derived when omitted.
+- Narratio does not auto-promote all generated analyze artifacts.
+- `restore` reads the same config/session inputs and restore scope is bounded by committed archive current state.

+
+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:
+
+- `previous_session_artifact`
+- `narratio.transcript.merged`
+- `narratio.transcript.polished`
+- `narratio.transcript.full`
+- `narratio.transcript.trimmed`
+- `narratio.bounds.session`
+- `narratio.artifact.<configured_artifact_key>`
+
+`pipeline.archive.promote_artifacts[].source` values:
+
+- `narratio.transcript.merged`
+- `narratio.transcript.polished`
+- `narratio.transcript.full`
+- `narratio.transcript.trimmed`
+- `narratio.bounds.session`
+- `narratio.artifact.<configured_artifact_key>`
+
+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.
+
+Restore-related implications:
+
+- restore remote identity requires archive S3 identity to resolve (`pipeline.storage.s3.bucket` and session prefix derivation inputs).
+- restore scope considers only committed current state and durable paths (`manifest.json`, `transcripts/**`, `artifacts/**`, optional `audio/**`).
+
+## 8. Full session reference
+
+| Path | Type | Required | Default |
+| --- | --- | --- | --- |
+| `session.session_id` | string | Yes | none |
+| `session.campaign` | string | Yes | none |
+| `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 | Yes | none |
+| `session.inputs.autocorrect_file` | string | Yes | none |
+| `session.inputs.glossary_file` | string | Yes | none |
+
+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.
+
+## 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/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).
+
+### 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.

-# Workspace Architecture Implementation Plan (Status)
-
-This document tracks the implemented workspace architecture and remaining work for v1.0.
-
-## Current Architecture (Implemented)
-
-Narratio now uses a canonical campaign-aware local layout:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/
-  manifest.json
-  current/
-    manifest.json
-    run_id.txt
-  inputs/
-  transcripts/
-  artifacts/
-  reports/
-  logs/
-  config/
-  runs/
-    {run_id}/
-      manifest.json
-      {stage}/
-        outputs/
-        logs/
-        reports/
-        config/
-        scratch/
-```
-
-Core behavior:
-
-- Session manifest remains the skip/resume source of truth.
-- Each invocation creates a run manifest at `runs/{run_id}/manifest.json`.
-- Stage execution writes run-local artifacts and promotes durable outputs to canonical session paths.
-- Archive uploads run records under `runs/{run_id}/`, applies promotion rules, then publishes `current/manifest.json` and `current/run_id.txt`.
-- Analyze input resolution uses centralized artifact IDs with alias support.
-- Forced upstream reruns mark downstream succeeded stages `stale` so later runs do not skip stale outputs.
-
-## Section 4 Sequence Status
-
-### Step 1: Campaign-aware session path model
-
-Status: complete.
-
-Implemented:
-
-- Campaign-aware session and run path helpers.
-- Campaign-aware artifact-store layout APIs.
-- Canonical session manifest pathing under `work/{campaign}/{session}`.
-
-### Step 2: Session manifest + run manifest scaffolding
-
-Status: complete.
-
-Implemented:
-
-- Invocation-scoped run manifest type and store methods.
-- Runner creates/saves run manifests per invocation.
-- Session manifest remains authoritative for idempotent stage skipping.
-
-### Step 3: Run-local stage execution + promotion
-
-Status: complete.
-
-Implemented:
-
-- Run-local stage directory layout under `runs/{run_id}/{stage}`.
-- Shared helpers for run-local output mapping and promotion to canonical durable paths.
-- Producer run provenance recorded on durable artifact outputs.
-
-### Step 4: Archive alignment
-
-Status: complete.
-
-Implemented:
-
-- Canonical run-root/session-root resolution.
-- Deterministic run-file collection and promotion source resolution.
-- Current-pointer publication ordering retained (`current/manifest.json` then `current/run_id.txt`).
-
-### Step 5: Artifact registry/resolver (analyze first consumer)
-
-Status: complete.
-
-Implemented:
-
-- Central artifact resolver with canonical IDs:
-  - `narratio.transcript.merged`
-  - `narratio.transcript.polished`
-  - `narratio.transcript.full`
-  - `narratio.transcript.trimmed`
-  - `narratio.bounds.session`
-  - `narratio.artifact.session_recap`
-- Backward-compatible aliases:
-  - `processed_transcript`
-  - `normalized_transcript`
-  - `trimmed_transcript`
-- Analyze stage switched to resolver-based source resolution.
-
-### Step 6: Minimal downstream invalidation for forced reruns
-
-Status: complete.
-
-Implemented:
-
-- Deterministic downstream invalidation based on canonical stage order.
-- On forced successful rerun of stage `X`, downstream succeeded stages are marked `stale`.
-- Resume and non-forced runs naturally re-execute stale stages.
-
-### Step 7: Legacy layout migration strategy
-
-Status: intentionally skipped.
-
-Decision:
-
-- Automatic migration and legacy fallback compatibility are intentionally not implemented.
-- The codebase targets canonical-only local layout behavior.
-- Legacy local workspace state, if present, should be recreated or migrated manually outside Narratio.
-
-## Remaining Work (v1.0)
-
-No required workspace/run-history migration steps remain from Section 4.
-
-Possible future enhancements (non-blocking):
-
-- Full checksum/input-graph stale detection.
-- Optional retention-policy expansion for run-history cleanup.
-- Broader artifact-resolver adoption across additional stage consumers.

-# Narratio Workspace, Run History, and Artifact Resolution Architecture
-
-## 1. Purpose
-
-This document defines the intended v1.0 architecture for Narratio's local workspace layout, run history model, durable session outputs, manifest responsibilities, and artifact resolution contract.
-
-Narratio is an idempotent session orchestrator. The command:
-
-```bash
-narratio run --session-id 2026-05-07
-```
-
-means "bring the identified session to its desired completed state." It does **not** mean "always create an entirely new independent output tree and ignore prior session state."
-
-This distinction drives the architecture:
-
-* A **session** is the durable domain object and idempotency boundary.
-* A **run** is an execution attempt that may update the session's durable state.
-* Durable outputs live at the session level.
-* Run-specific outputs, logs, generated configs, scratch files, and diagnostics live under `runs/{run_id}/`.
-* Successful stage outputs are promoted from run-local locations into canonical session-level locations.
-* The session manifest records current durable state.
-* Run manifests record execution history and debugging/provenance details.
-
-This model intentionally mirrors the S3 archive model: session-level current artifacts are distinct from run-record history.
-
-## 2. Core Concepts
-
-### 2.1 Session
-
-A session is the stable unit of work identified by `campaign_id` and `session_id`.
-
-Examples:
-
-```text
-campaign_id = dilfs
-session_id  = 2026-05-07
-```
-
-The session directory represents the current durable local state for that session. Re-running Narratio for the same session should consult this state, skip already-completed stages by default, and produce no changes unless work is incomplete, stale, forced, or explicitly selected.
-
-### 2.2 Run
-
-A run is a particular execution attempt identified by a generated `run_id`, for example:
-
-```text
-20260517T174748Z-abcd1234
-```
-
-A run may execute all stages or only a sparse subset of stages. Sparse runs are expected and desirable when the user invokes `--force`, `run-stage`, or a stage-limited command.
-
-Run directories are provenance/debug records. They should reflect what actually happened during that invocation, not a synthetic complete pipeline layout.
-
-### 2.3 Durable Output
-
-A durable output is a canonical session-level artifact intended for later stages, user consumption, archive promotion, or future idempotency decisions.
-
-Examples:
-
-```text
-transcripts/merged.json
-transcripts/processed.json
-transcripts/normalized.json
-transcripts/trimmed.json
-artifacts/session_recap.md
-```
-
-Durable outputs live directly under the session directory, not under a particular run directory.
-
-### 2.4 Run-Local Output
-
-A run-local output is the file initially produced by a stage during a specific run. After validation, durable outputs are promoted from run-local paths to session-level canonical paths.
-
-Run-local outputs, logs, generated configs, reports, and scratch files should remain under:
-
-```text
-runs/{run_id}/{stage}/...
-```
-
-## 3. Local Workspace Layout
-
-The canonical local workspace layout is:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/
-  manifest.json
-  current/
-    manifest.json
-    run_id.txt
-  inputs/
-  transcripts/
-  artifacts/
-  reports/
-  logs/
-  config/
-  runs/
-    {run_id}/
-      manifest.json
-      prepare/
-      transcribe/
-      merge/
-      polish/
-      normalize/
-      trim/
-      analyze/
-      archive/
-      notify/
-```
-
-Not every directory must exist at all times. Directories should be created idempotently when needed.
-
-### 3.1 Session Root
-
-The session root is:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/
-```
-
-The session root is the stable local home for the session. It is the default base for resolving canonical artifact paths.
-
-The only files that should live directly in the session root are core session-state files, primarily:
-
-```text
-manifest.json
-```
-
-Lock files may also be session-root scoped if the implementation uses file locks there, but transient locks should not be treated as durable artifacts.
-
-### 3.2 Session-Level Canonical Directories
-
-The following directories contain current durable session state:
-
-```text
-inputs/
-transcripts/
-artifacts/
-reports/
-logs/
-config/
-current/
-```
-
-Recommended meanings:
-
-| Directory      | Purpose                                                                       |
-| -------------- | ----------------------------------------------------------------------------- |
-| `inputs/`      | Materialized or copied input files used by the current durable session state. |
-| `transcripts/` | Canonical transcript tiers.                                                   |
-| `artifacts/`   | User-facing and machine-readable generated artifacts.                         |
-| `reports/`     | Canonical stage reports worth preserving at the session level.                |
-| `logs/`        | Optional session-level logs or promoted/latest logs.                          |
-| `config/`      | Optional session-level generated config snapshots or promoted/latest configs. |
-| `current/`     | Current published session pointers, mirroring the archive backend.            |
-
-Canonical durable outputs should use stable paths under these directories.
-
-### 3.3 Run History Directory
-
-Run history lives under:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/runs/{run_id}/
-```
-
-Each run directory records what happened during that invocation. A run may contain all stage directories or only a sparse subset.
-
-Example full run:
-
-```text
-runs/20260517T174748Z-abcd1234/
-  manifest.json
-  prepare/
-  transcribe/
-  merge/
-  polish/
-  normalize/
-  trim/
-  analyze/
-  archive/
-  notify/
-```
-
-Example sparse forced analyze run:
-
-```text
-runs/20260518T030000Z-efgh5678/
-  manifest.json
-  analyze/
-```
-
-Example sparse polish-through-analyze rerun:
-
-```text
-runs/20260518T041500Z-a1b2c3d4/
-  manifest.json
-  polish/
-  normalize/
-  trim/
-  analyze/
-```
-
-Run directories should not create stage folders for stages that were not selected, executed, skipped, or otherwise considered during that run unless there is a clear diagnostic reason to do so.
-
-### 3.4 Stage Run-Local Directories
-
-Each stage receives a run-local directory:
-
-```text
-runs/{run_id}/{stage}/
-```
-
-Within that stage directory, the stage may use subdirectories such as:
-
-```text
-outputs/
-logs/
-reports/
-config/
-scratch/
-```
-
-For example:
-
-```text
-runs/{run_id}/polish/
-  outputs/transcripts/processed.json
-  reports/audita.polish.report.json
-  logs/stdout.log
-  logs/stderr.log
-  config/audita.polish.generated.yml
-  scratch/
-```
-
-The exact internal layout of a stage directory may vary by stage, but it should be deterministic, documented, and generated through centralized path helpers rather than ad hoc path joins.
-
-## 4. Promotion Model
-
-Narratio uses stage-level promotion with immediate promotion after successful validation.
-
-The stage lifecycle is:
-
-1. Resolve required inputs from the current session state and/or run-local context.
-2. Create the run-local stage directory.
-3. Execute the stage, writing outputs under `runs/{run_id}/{stage}/...`.
-4. Validate run-local outputs.
-5. Promote durable outputs into session-level canonical paths.
-6. Update the session manifest.
-7. Update the run manifest.
-
-Promotion means an atomic or effectively atomic copy/rename from a run-local path to a session-level canonical path.
-
-Example:
-
-```text
-runs/{run_id}/polish/outputs/transcripts/processed.json
-```
-
-is promoted to:
-
-```text
-transcripts/processed.json
-```
-
-Promotion should be safe and deterministic:
-
-* Validate before promotion.
-* Write promoted files atomically where possible.
-* Never leave partially written durable outputs.
-* Record the producing `run_id` in the session manifest.
-* Preserve run-local files for debugging unless retention policy deletes them.
-
-## 5. Promotion Policy: Option A
-
-Narratio uses immediate stage-level promotion.
-
-If a selected stage succeeds, its durable outputs are promoted immediately, even if a later selected stage fails.
-
-Example:
-
-```bash
-narratio run --session-id 2026-05-07 --force --stages polish,normalize,trim,analyze
-```
-
-If `polish` succeeds and `normalize` fails:
-
-* `transcripts/processed.json` may be updated from the new run.
-* `normalize`, `trim`, and `analyze` should not be marked succeeded for the new input state.
-* Downstream outputs may now be stale relative to the newly promoted polished transcript.
-
-This policy is simpler, transparent, and consistent with stage-level resumability. It does require explicit stale/invalidation handling.
-
-## 6. Stale and Invalidation Semantics
-
-Full checksum-based stale detection may be implemented later. Before that exists, Narratio should still use a simple deterministic invalidation rule for forced or explicit upstream reruns.
-
-When a stage is successfully re-executed and promoted, downstream stages should be marked stale unless they are also re-executed successfully in the same command invocation.
-
-Example stage order:
-
-```text
-prepare -> transcribe -> merge -> polish -> normalize -> trim -> analyze -> archive -> notify
-```
-
-If `polish` is forced and promoted, then the following downstream stages should be invalidated unless rerun successfully:
-
-```text
-normalize
-trim
-analyze
-archive
-notify
-```
-
-A stale stage is not equivalent to a failed stage. It means its current durable outputs may no longer correspond to current upstream inputs or configuration.
-
-Minimum manifest state model:
-
-```text
-pending
-running
-succeeded
-failed
-skipped
-stale
-```
-
-If adding a new `stale` state is too invasive for v1.0, the implementation should at least record stale metadata or clear downstream success markers in a way that prevents accidental idempotent skips based on obsolete outputs.
-
-## 7. Manifest Responsibilities
-
-Narratio should distinguish between session manifests and run manifests.
-
-The same underlying Go types may be reused where practical, but the concepts should remain separate.
-
-### 7.1 Session Manifest
-
-Path:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/manifest.json
-```
-
-The session manifest answers:
-
-```text
-What is the current durable state of this session?
-```
-
-It should record:
-
-* campaign ID
-* session ID
-* current or latest run ID
-* current stage states
-* canonical durable output refs
-* artifact IDs and paths
-* producing run ID for each current stage output
-* relevant input/config checksums when available
-* stale/invalidated stage information
-* archive/current publication metadata
-
-A session's durable state may be a composite of multiple runs.
-
-For example:
-
-```text
-transcripts/merged.json      produced by run A
-transcripts/processed.json   produced by run B
-transcripts/normalized.json  produced by run B
-transcripts/trimmed.json     produced by run B
-artifacts/session_recap.md   produced by run C
-```
-
-This is valid and expected.
-
-### 7.2 Run Manifest
-
-Path:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/runs/{run_id}/manifest.json
-```
-
-The run manifest answers:
-
-```text
-What happened during this specific execution attempt?
-```
-
-It should record:
-
-* run ID
-* campaign ID
-* session ID
-* command mode and selected stages
-* force flags or stage selection flags
-* stages considered during this run
-* stages executed during this run
-* stages skipped during this run and reasons
-* run-local output paths
-* promoted output paths
-* logs
-* reports
-* generated configs
-* timings
-* errors
-* non-secret subprocess invocation metadata
-
-Run manifests are primarily for debugging, auditability, and archive history.
-
-## 8. Idempotency and Resume Behavior
-
-The idempotency boundary is the session, not the run.
-
-By default:
-
-```bash
-narratio run --session-id 2026-05-07
-```
-
-should consult the session manifest and skip stages that are already succeeded and not stale.
-
-If all stages are already complete, the command should execute zero stages and report that the session is already complete.
-
-Forced execution creates a new run record but updates session-level durable state only for stages that actually succeed and promote outputs.
-
-Examples:
-
-```bash
-narratio run --session-id 2026-05-07 --force
-```
-
-Creates a new run and attempts to re-execute the selected/default stage set.
-
-```bash
-narratio run-stage --session-id 2026-05-07 analyze --force
-```
-
-Creates a sparse run that executes only `analyze`, then promotes updated analysis artifacts if successful.
-
-```bash
-narratio resume --session-id 2026-05-07
-```
-
-Uses the session manifest to determine what remains incomplete or stale. Resume does not need to resume the same `run_id` unless the implementation explicitly supports resuming an interrupted active run.
-
-## 9. Artifact Resolution Contract
-
-Narratio should provide a first-class artifact registry and resolver.
-
-The resolver maps symbolic artifact source names to canonical session-level paths and manifest output kinds.
-
-Stages and adapters should not hardcode path fragments when resolving cross-stage inputs. They should ask the artifact resolver for the current durable artifact by ID.
-
-### 9.1 Canonical Artifact IDs
-
-Preferred artifact IDs should be namespaced:
-
-```text
-narratio.transcript.merged
-narratio.transcript.polished
-narratio.transcript.full
-narratio.transcript.trimmed
-narratio.bounds.session
-narratio.artifact.session_recap
-```
-
-Recommended initial registry:
-
-| Artifact ID                       | Canonical Path                  | Producer Stage | Output Kind              | Meaning                               |
-| --------------------------------- | ------------------------------- | -------------- | ------------------------ | ------------------------------------- |
-| `narratio.transcript.merged`      | `transcripts/merged.json`       | `merge`        | `transcript_merged`      | Deterministic Seriatim merge.         |
-| `narratio.transcript.polished`    | `transcripts/processed.json`    | `polish`       | `transcript_processed`   | Full Audita-polished transcript.      |
-| `narratio.transcript.full`        | `transcripts/normalized.json`   | `normalize`    | `transcript_normalized`  | Preferred full normalized transcript. |
-| `narratio.transcript.trimmed`     | `transcripts/trimmed.json`      | `trim`         | `transcript_trimmed`     | Gameplay-only transcript.             |
-| `narratio.bounds.session`         | `artifacts/session_bounds.json` | `trim`         | `session_bounds`         | Trim bounds selected for the session. |
-| `narratio.artifact.session_recap` | `artifacts/session_recap.md`    | `analyze`      | `artifact_session_recap` | Generated session recap.              |
-
-### 9.2 Backward-Compatible Aliases
-
-Existing source names should remain supported:
-
-| Legacy Source           | Preferred Artifact ID          |
-| ----------------------- | ------------------------------ |
-| `processed_transcript`  | `narratio.transcript.polished` |
-| `normalized_transcript` | `narratio.transcript.full`     |
-| `trimmed_transcript`    | `narratio.transcript.trimmed`  |
-
-These aliases may be supported silently for v1.0. Documentation should prefer namespaced IDs.
-
-### 9.3 Resolver Behavior
-
-Artifact resolution should follow this order:
-
-1. Normalize aliases to canonical artifact IDs.
-2. Look for a current output reference in the session manifest.
-3. Fall back to the canonical session-level path.
-4. If the artifact is required, fail clearly if missing.
-5. If the artifact is optional and missing, omit it from the downstream invocation.
-6. Validate the artifact using the expected content validator.
-7. Return a resolved artifact record containing ID, path, producer stage, output kind, and provenance.
-
-Example conceptual result:
-
-```json
-{
-  "id": "narratio.transcript.trimmed",
-  "path": "/var/lib/narratio/work/dilfs/2026-05-07/transcripts/trimmed.json",
-  "producer_stage": "trim",
-  "producer_run_id": "20260517T174748Z-abcd1234",
-  "output_kind": "transcript_trimmed",
-  "content_type": "application/json"
-}
-```
-
-### 9.4 Artifact Validation
-
-Transcript artifacts must be valid JSON with a top-level `segments` array.
-
-Markdown/text artifacts must exist and be non-empty when required.
-
-Bounds artifacts must match the expected bounds schema and refer to segment IDs in the same transcript ID space used by the trim stage.
-
-Validation should happen before a resolved artifact is passed to another stage or external subprocess.
-
-## 10. Analyze Stage Implications
-
-The analyze stage should consume artifacts through the artifact resolver.
-
-Preferred Scriptorium config shape:
-
-```yaml
-scriptorium:
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: "dnd.session_recap"
-      output_path: "artifacts/session_recap.md"
-      inputs:
-        transcript:
-          source: "narratio.transcript.trimmed"
-          required: true
-```
-
-Additional artifacts can choose different transcript tiers:
-
-```yaml
-scriptorium:
-  artifacts:
-    table_summary:
-      enabled: true
-      prompt_id: "dnd.table_summary"
-      output_path: "artifacts/table_summary.md"
-      inputs:
-        transcript:
-          source: "narratio.transcript.full"
-          required: true
-```
-
-For v1.0, Narratio does not need a generic DAG engine. It may execute configured analyze artifacts in deterministic order and allow later artifacts to consume earlier artifacts only when that relationship is explicit and unambiguous.
-
-Rules:
-
-* Artifact inputs resolve from current session-level durable state.
-* Outputs are first written run-locally.
-* Successful analyze outputs are promoted to session-level `artifacts/` paths.
-* Manifest output refs record the producing run ID.
-* Optional inputs are omitted when unavailable.
-* Required missing inputs fail before invoking Scriptorium.
-
-## 11. Archive Alignment
-
-Local workspace semantics should mirror archive semantics.
-
-Local session-level durable paths:
-
-```text
-work/{campaign}/{session}/transcripts/trimmed.json
-work/{campaign}/{session}/artifacts/session_recap.md
-work/{campaign}/{session}/current/manifest.json
-work/{campaign}/{session}/current/run_id.txt
-work/{campaign}/{session}/runs/{run_id}/...
-```
-
-should map naturally to remote archive paths:
-
-```text
-{root_prefix}/campaigns/{campaign}/sessions/{session}/transcripts/trimmed.json
-{root_prefix}/campaigns/{campaign}/sessions/{session}/artifacts/session_recap.md
-{root_prefix}/campaigns/{campaign}/sessions/{session}/current/manifest.json
-{root_prefix}/campaigns/{campaign}/sessions/{session}/current/run_id.txt
-{root_prefix}/campaigns/{campaign}/sessions/{session}/runs/{run_id}/...
-```
-
-The archive stage should publish run records and promoted current artifacts consistently with the local model.
-
-`current/run_id.txt` remains the effective commit marker for the archived current session state.
-
-## 12. Path Helper Requirements
-
-All code should use centralized path helpers for workspace paths.
-
-Stage code should not manually assemble durable cross-stage paths using raw string joins except through the path model.
-
-Recommended helper surface:
-
-```text
-SessionRoot(campaignID, sessionID)
-SessionManifestPath(campaignID, sessionID)
-SessionCurrentDir(campaignID, sessionID)
-SessionTranscriptsDir(campaignID, sessionID)
-SessionArtifactsDir(campaignID, sessionID)
-SessionReportsDir(campaignID, sessionID)
-SessionLogsDir(campaignID, sessionID)
-SessionConfigDir(campaignID, sessionID)
-RunsDir(campaignID, sessionID)
-RunRoot(campaignID, sessionID, runID)
-RunManifestPath(campaignID, sessionID, runID)
-RunStageDir(campaignID, sessionID, runID, stage)
-RunStageOutputsDir(campaignID, sessionID, runID, stage)
-RunStageLogsDir(campaignID, sessionID, runID, stage)
-RunStageReportsDir(campaignID, sessionID, runID, stage)
-RunStageConfigDir(campaignID, sessionID, runID, stage)
-CanonicalArtifactPath(campaignID, sessionID, artifactID)
-```
-
-Path helpers should enforce safe relative paths for configured output paths:
-
-* reject absolute paths unless explicitly allowed for a particular config field
-* reject `..` traversal
-* normalize separators
-* preserve deterministic output paths
-
-## 13. Directory Creation Policy
-
-Directory creation should be centralized and idempotent.
-
-Recommended policy:
-
-* `prepare` ensures the baseline session directory structure exists.
-* Every stage also calls shared layout helpers to ensure its required run-local directories exist before writing.
-* `run-stage` should not depend on a prior `prepare` invocation merely to create folders.
-* Missing directories should be created with appropriate permissions.
-* Directory creation should not imply stage success.
-
-This provides consistent layout while keeping direct stage execution robust.
-
-## 14. Cleanup and Retention
-
-Cleanup must preserve the distinction between durable session state and run history.
-
-Workspace cleanup after successful archive may remove selected local directories only according to explicit configuration.
-
-Potential retention policies:
-
-```text
-keep_all_runs
-keep_failed_runs
-keep_last_n_runs
-delete_run_after_success
-```
-
-For v1.0, conservative retention is preferred:
-
-* Do not delete durable session-level outputs unless explicitly requested.
-* Do not delete failed run directories by default.
-* If cleanup is enabled, remove only documented run-scoped or spool-scoped paths.
-* Local development audio inputs must never be deleted by workspace cleanup.
-
-## 15. Canonical-Only Layout Policy
-
-Narratio now supports only the canonical campaign-aware layout:
-
-```text
-{workspace.root}/work/{campaign_id}/{session_id}/manifest.json
-{workspace.root}/work/{campaign_id}/{session_id}/runs/{run_id}/...
-```
-
-Legacy session-only layout compatibility is intentionally not implemented.
-
-If legacy workspace data exists, operators should recreate or manually migrate that data outside Narratio before running v1.0 commands.
-
-## 16. Documentation Updates Required
-
-The following documentation should be updated to reflect this architecture:
-
-* `README.md`
-* `docs/architecture.md`
-* a dedicated workspace/run-history document, such as this file
-* S3/archive documentation
-* analyze/artifact configuration documentation
-* example pipeline files
-
-Documentation should consistently use the following terms:
-
-| Term             | Meaning                                                                |
-| ---------------- | ---------------------------------------------------------------------- |
-| Session          | Durable domain object and idempotency boundary.                        |
-| Run              | Execution attempt that may update session state.                       |
-| Durable output   | Canonical current session-level output.                                |
-| Run-local output | Output produced inside a specific run directory before promotion.      |
-| Promotion        | Validated copy/rename from run-local output to durable session output. |
-| Session manifest | Current durable state of the session.                                  |
-| Run manifest     | Execution record for a particular run.                                 |
-| Artifact ID      | Symbolic source name resolved by the artifact registry.                |
-
-## 17. Architectural Invariants
-
-The following invariants should hold after implementation:
-
-1. `session_id` remains the idempotency boundary for normal operator commands.
-2. `run_id` identifies an execution attempt, not the primary durable workspace.
-3. Session-level canonical artifacts are the default inputs for downstream stages.
-4. Run-local outputs are promoted only after validation.
-5. A session's current durable state may be composed of outputs from multiple runs.
-6. Sparse run directories are valid and expected.
-7. The session manifest records current stage/artifact state and producer run IDs.
-8. The run manifest records what happened during one invocation.
-9. Artifact consumers resolve symbolic artifact IDs through a registry/resolver.
-10. Local workspace semantics mirror S3 archive semantics.
-11. Directory creation is centralized and idempotent.
-12. Stage code uses path helpers rather than ad hoc path construction.
-13. Forced upstream reruns invalidate downstream stage success unless downstream stages are rerun successfully.
-14. Cleanup never removes durable session outputs or local development inputs unless explicitly configured to do so.
-
-## 18. Implementation Guidance
-
-A practical implementation sequence is:
-
-1. Add this architecture document.
-2. Add or revise path model helpers for session roots, run roots, stage directories, and canonical artifact paths.
-3. Introduce session manifest versus run manifest concepts.
-4. Route stage outputs through run-local directories.
-5. Add promotion helpers with validation and atomic writes.
-6. Update existing stages to promote durable outputs to session-level canonical paths.
-7. Add artifact registry and resolver.
-8. Update analyze to use artifact IDs and aliases.
-9. Add simple downstream stale invalidation for forced upstream reruns.
-10. Align archive/local path behavior and documentation.
-11. Update examples and README.
-12. Add tests for idempotency, sparse forced runs, promotion, manifest provenance, and artifact resolution.

+# 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.

+
+## 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.
+
+The full configuration reference should be canonical.
+
+### docs/cli.md
+
+**Audience:** users, administrators, operators
+
+Required for CLI applications.
+
+It should include, in order:
+
+1. shortest useful command;
+2. command overview;
+3. complete flag reference;
+4. common workflows;
+5. diagnostic or recovery commands, if applicable.
+
+Explain when commands are useful, not just their syntax.
+
+### docs/operations.md
+
+**Audience:** administrators, operators
+
+Required for applications that maintain state, support resume behavior, run multiple stages, write durable artifacts, use remote storage, or require recovery procedures.
+
+It should cover:
+
+- normal workflow;
+- filesystem layout;
+- remote storage layout, if applicable;
+- logs and manifests;
+- resume/retry behavior;
+- cleanup behavior;
+- archive/backup behavior;
+- safe recovery procedures;
+- operational caveats.
+
+### docs/troubleshooting.md
+
+**Audience:** administrators, operators
+
+Recommended once recurring failure modes exist.
+
+Each entry should include:
+
+- symptom;
+- likely cause;
+- 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.
+
+It should include:
+
+- repository layout;
+- build/test commands;
+- coding conventions;
+- dependency policy;
+- how to add config fields;
+- how to add CLI flags;
+- 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;
+4. config fields used;
+5. external adapters used;
+6. state or manifest behavior, if applicable;
+7. skip/resume behavior, if applicable;
+8. failure behavior;
+9. tests to inspect before changing;
+10. architectural invariants.
+
+### docs/roadmap/
+
+**Audience:** maintainers, developers, LLM coding agents
+
+This is the only place for planned, future, aspirational, experimental, or unimplemented work.
+
+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`):
+- merged transcript path
+- glossary path
+- output processed 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`):
+- processed 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 processed 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 processed 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
-
+- Processed 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/campaign-7/session-42/transcript.polished.md \
-  --input glossary=/work/campaign-7/session-42/glossary.yml \
-  --out /work/campaign-7/session-42/artifacts/session_recap.md
-```
-
-Structured events:
-
-```bash
-scriptorium run \
-  --prompt dnd.structured_events \
-  --input transcript=/work/campaign-7/session-42/transcript.polished.md \
-  --out /work/campaign-7/session-42/artifacts/structured_events.json
-```
-
-Glossary suggestions:
-
-```bash
-scriptorium run \
-  --prompt dnd.glossary_suggestions \
-  --input transcript=/work/campaign-7/session-42/transcript.polished.md \
-  --input previous_recap=/work/campaign-7/session-41/artifacts/session_recap.md \
-  --out /work/campaign-7/session-42/artifacts/glossary_suggestions.md
-```
-
-Player-facing summary:
-
-```bash
-scriptorium run \
-  --prompt dnd.player_summary \
-  --input transcript=/work/campaign-7/session-42/transcript.polished.md \
-  --input structured_events=/work/campaign-7/session-42/artifacts/structured_events.json \
-  --out /work/campaign-7/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
+# Integration: seriatim
-
+
-`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.
+
-
+## Inputs and Outputs
-## Usage
+Inputs:
-
+- `MergeRequest`: raw/normalized transcript inputs, output path, optional report, speaker/autocorrect paths, logs/config
-Run from source:
+- `NormalizeRequest`: input transcript, output path, schema, optional report, timeout/log/config
-
+- `TrimRequest`: input transcript, output path, keep selector, timeout/log/config
-```sh
+
-go run ./cmd/seriatim merge \
+Outputs:
-  --input-file samples/raw/2026-04-19-Eric_Rakestraw.json \
+- `MergeResult`, `NormalizeResult`, `TrimResult` with output paths, logs/config paths, exit code, duration, binary provenance, and metadata.
-  --input-file samples/raw/2026-04-19-Mike_Brown.json \
+
-  --output-file merged.json
+## Boundaries
-```
+Owns:
-
+- Validated deterministic CLI invocation construction
-Optional report output:
+- Optional env tuning propagation for merge
-
+- Invocation config file emission
-```sh
+- JSON output validation
-go run ./cmd/seriatim merge \
+
-  --input-file eric.json \
+Does not own:
-  --input-file mike.json \
+- Transcript input selection/promotion logic (stage-owned)
-  --output-file merged.json \
+- Bounds computation (scriptorium/trim-stage-owned)

-`merge` flags:
+## Skip and Resume Behavior
-
+- Adapter has no skip/resume logic. Runner controls stage execution.
-| Flag | Required | Default | Description |
+
-| --- | --- | --- | --- |
+## Failure Behavior
-| `--input-file` | Yes | none | Input transcript JSON file. Repeat once per speaker/input file. |
+- Constructor fails for invalid binary/timeout/output-schema/coalesce-gap.
-| `--output-file` | Yes | none | Merged transcript JSON output path. |
+- Merge fails on missing output path/inputs/report path (if enabled), subprocess errors, invalid merged output JSON, invalid report JSON.
-| `--report-file` | No | none | Optional report JSON output path. |
+- Normalize fails on missing input/output, invalid schema, subprocess errors, invalid normalized output JSON shape, invalid report JSON.
-| `--speakers` | No | none | Speaker map YAML file. When omitted, input file basenames are used as speaker labels. |
+- Trim fails on missing input/output/keep selector, subprocess errors, invalid trimmed output JSON shape.
-| `--autocorrect` | No | none | Autocorrect rules YAML file. When omitted, the default `autocorrect` module leaves text unchanged. |

+- `internal/adapters/seriatim/subprocess_test.go`
-| `--output-schema` | No | `seriatim-intermediate` | JSON output contract. Allowed values are `seriatim-minimal`, `seriatim-intermediate`, and `seriatim-full`. If omitted, the runtime default is used; consumers that depend on a specific shape should set this explicitly. |
+- `internal/adapters/seriatim/fake_test.go`

-| `SERIATIM_OUTPUT_SCHEMA` | `seriatim-intermediate` | Output schema used when `--output-schema` is not explicitly provided. Allowed values are `seriatim-minimal`, `seriatim-intermediate`, and `seriatim-full`. The CLI flag takes precedence. |
-| `SERIATIM_OVERLAP_WORD_RUN_GAP` | `1.0` | Maximum gap in seconds between adjacent timed words when `resolve-overlaps` builds word-run replacement segments. Must be a positive float. |
-| `SERIATIM_OVERLAP_WORD_RUN_REORDER_WINDOW` | `1.0` | Near-start window in seconds for ordering replacement word runs shortest-first. Must be a positive float. |

-
-## 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
-```

+Runtime env boundary fields (`internal/stage.Env`):
+- `whisperx.Client`
+- `seriatim.Runner`
+- `audita.Runner`
+- `scriptorium.Runner`
+- `storage.ObjectStore`
+- `notify.Sender`
+- `analyzer.Runner`
+
+Current execution usage:
+- Actively used by implemented stages: `WhisperX`, `Seriatim`, `Audita`, `Scriptorium`, `ObjectStore`, `Notifier`.
+- Present but not used by implemented stage set: `Analyzer`, 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`.
+- 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.

+# Internal: Artifacts
+
+## Purpose
+Define Narratio's artifact identity and resolution model for built-in transcript/bounds artifacts and runtime-configured analyze artifacts.
+
+## Inputs and outputs
+Inputs:
+- artifact sources from config/runtime (`pipeline.scriptorium.artifacts.*.inputs.*.source`)
+- session paths and optional session manifest stage outputs
+- runtime artifact catalog state for configured artifact sources
+
+Outputs:
+- resolved local artifact path and provenance (`ResolvedSessionArtifact`)
+- runtime catalog entries for planned/executable/available artifacts
+- validation errors for unsupported, missing, or invalid artifact sources
+
+## Boundaries
+Owns:
+- built-in artifact registry and content validation rules
+- runtime artifact catalog for configured artifact source IDs
+- source resolution behavior for built-in and configured artifact sources
+
+Does not own:
+- artifact generation (stages produce files)
+- manifest transition policy
+- archive promotion behavior
+
+## Config fields used
+- `pipeline.scriptorium.artifacts.<name>.enabled`
+- `pipeline.scriptorium.artifacts.<name>.output_path`
+- `pipeline.scriptorium.artifacts.<name>.inputs.<key>.source`
+
+## External adapters used
+- none
+
+## State and manifest behavior
+Built-in registry entries:
+
+| Artifact ID | Canonical file | Producer stage | Output kind |
+| --- | --- | --- | --- |
+| `narratio.transcript.merged` | `transcripts/merged.json` | `merge` | `transcript_merged` |
+| `narratio.transcript.polished` | `transcripts/processed.json` | `polish` | `transcript_processed` |
+| `narratio.transcript.full` | `transcripts/normalized.json` | `normalize` | `transcript_normalized` |
+| `narratio.transcript.trimmed` | `transcripts/trimmed.json` | `trim` | `transcript_trimmed` |
+| `narratio.bounds.session` | `artifacts/session_bounds.json` | `trim` | `session_bounds` |
+
+Runtime catalog entries include built-ins and configured `narratio.artifact.<name>` sources.
+
+Catalog states:
+- `planned`: source is registered and known for this run
+- `executable`: configured artifact is selected for analyze execution
+- `available`: artifact has a usable file path (generated this run or reused from disk)
+
+Resolution behavior:
+- built-in sources resolve via manifest producer outputs first, then canonical fallback path
+- configured `narratio.artifact.<name>` sources resolve through runtime catalog availability
+- configured source lookup requires catalog context
+
+Configured artifact provenance values:
+- `generated.current_analyze_run`
+- `filesystem.disabled_artifact_output`
+
+Content validation:
+- transcript built-ins: JSON with top-level `segments` array
+- bounds built-in: valid JSON
+- configured artifacts: non-empty text file
+
+## Skip and resume behavior
+- resolver and catalog have no direct skip/resume decisions
+- stage/runner skip-resume behavior consumes catalog/resolver results
+
+## Failure behavior
+- unsupported source -> source validation error
+- known source unavailable -> `ErrSessionArtifactNotFound`
+- configured source without catalog -> resolution error
+- resolved file with invalid content -> validation error
+
+## Tests to inspect before changing
+- `internal/artifacts/artifact_resolver_test.go`
+- `internal/artifacts/catalog_test.go`
+- `internal/stage/analyze_test.go`

+
+## Architectural invariants
+- built-in IDs are static and registry-backed
+- configured artifact IDs are runtime-derived (`narratio.artifact.<name>`) and catalog-backed
+- built-in/source resolution remains deterministic and validation-gated

+# Internal: Command Restore
+
+## Purpose
+Define the implemented `narratio restore` command contract: committed remote-state discovery, deterministic planning, safe file installation, conflict policy, and restore reporting.
+
+## Inputs and outputs
+Inputs:
+- CLI flags: `--config`, `--session`, `--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.
+- `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.
+- 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`.
+
+## 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.
+- 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/**`
+  - 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 from runtime (`--artifacts`) when provided
+- resolved artifact input sources declared per artifact (`inputs.*.source`)
+- optional previous-session file inputs (`previous_session_artifact`)
+
+Outputs:
+- one promoted output file per executed configured artifact at that artifact's configured `output_path`
+- stage metadata containing generated artifact entries and reused disabled-artifact entries
+
+## Boundaries
+Owns:
+- runtime artifact catalog construction for analyze execution
+- selected-artifact planning and dependency ordering
+- per-artifact input resolution, var resolution, timeout/render-debug resolution
+- Scriptorium run/render invocation for each selected artifact
+- run-local output generation and canonical promotion
+
+Does not own:
+- transcript generation/processing stages

+- per-artifact resume semantics
+
+## Config Fields Used
+- `session.session_id`
+- `session.campaign`
+- `pipeline.workspace.root`
+- `pipeline.scriptorium.binary`
+- `pipeline.scriptorium.config_path`
+- `pipeline.scriptorium.timeout`

+  - `vars`
+
+## External Adapters Used
+- Scriptorium adapter:
+  - optional `RenderArtifact` (render debug)
+  - `RunArtifact` (artifact generation)
+
+## State and Manifest Behavior
+- If `pipeline.scriptorium` is absent, stage returns success metadata with `skipped=true`.
+- If no artifacts are configured, stage returns success metadata with `skipped=true`.
+- If zero artifacts are executable after `enabled` + `--artifacts` filtering, stage returns success metadata with `skipped=true`.
+- Builds runtime catalog with built-ins and configured artifacts.
+- Non-executable configured artifacts are marked available only when their configured output file exists and is valid on disk.
+- Executes selected configured artifacts in topological order with deterministic tie-breaking.
+- For each generated artifact, records metadata fields including `name`, `source_id`, `output_kind`, `path`, `prompt_id`, `profile_id`, and `provenance`.
+- Reused disabled artifacts are recorded separately in `reused_artifacts` with provenance `filesystem.disabled_artifact_output`.
+
+## Skip and Resume Behavior
+- Runner-level skip applies when analyze is already `succeeded` and `--force` is not set.
+- Analyze remains stage-scoped for resume/skip; there is no per-artifact resume state.
+- `--artifacts` filters which configured artifacts are executable when analyze runs; it does not imply `--force`.
+
+## Failure Behavior
+- Fails on invalid dependency ordering, unavailable required configured inputs, invalid built-in input prerequisites, render/run adapter failures, validation-failed adapter results, or missing/empty outputs.
+- Required configured dependency missing from catalog availability fails clearly before invocation.
+- Optional missing inputs are omitted.

+- `internal/artifacts/catalog_test.go`
+- `internal/artifacts/artifact_resolver_test.go`
+- `internal/adapters/scriptorium/subprocess_test.go`
+
+## Architectural Invariants
+- Configured artifacts are identified by `narratio.artifact.<name>` source IDs.
+- Artifact-to-artifact references rely on explicit `depends_on` declarations validated in config.
+- Generated analyze outputs are treated uniformly as Scriptorium artifacts.
+- Successful outputs must exist and be non-empty before promotion.

+  - upload counts/paths
+  - `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 required promotion source, upload failures, or pointer write failures.
+- Pointer semantics are fail-safe: `current/run_id.txt` is not written if prior required uploads fail.

+
+## Inputs and Outputs
+Inputs:
+- `audio/*.flac` prepared by `prepare`
+
+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.language`
+- `pipeline.whisperx.timeout`
+- `pipeline.whisperx.retries`
+- `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

+Outputs:
+- `transcripts/trimmed.json` (or configured trim output path)
+- when trim enabled: `artifacts/session_bounds.json`
+
+## Boundaries

+  - `RunArtifact` for bounds output
+- Seriatim adapter:
+  - `Trim` when bounds indicate trimming is required
+
+## State and Manifest Behavior
+- Reads normalized transcript from normalize manifest outputs when available; falls back to canonical path.
+- Uses run-local outputs/logs/reports/config/scratch paths when run layout is enabled.
+- Promotes canonical trimmed transcript; promotes session bounds when trim enabled.
+- Records bounds diagnostics, trim action, keep selector, and adapter metadata.
+
+## Skip and Resume Behavior
+- Runner-level skip applies when already succeeded and not forced.
+- Forced reruns can stale downstream succeeded stages.
+- When `trim.enabled=false`, stage still succeeds by copying normalized to trimmed output.
+
+## Failure Behavior
+- Fails on missing/invalid normalized transcript.
+- With trim enabled, fails on missing adapters/config, bounds generation/validation errors, invalid bounds JSON, invalid range/segment ids, trim adapter failures, or invalid trimmed output.

+
+## Inputs and outputs
+Inputs:
+- Resolved storage config (`pipeline.storage.*`).
+- Bucket-relative object keys and local file paths from stage/app orchestration.
+
+Outputs:
+- Listed/downloaded/uploaded object metadata (`ObjectInfo`).
+- Existence checks and storage-layer errors.
+
+## Boundaries
+Owns:

+- `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/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.

+# 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/`)
+- 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`
+- `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 spool/work paths and S3 provenance in `manifest.Inputs`.
+
+## 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.
+- Cleanup only targets run-scoped directories and must never delete configured root directories.

+# 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. Upload session `.flac` files to object storage under the configured session audio prefix.
+2. Run Narratio:
+
+```bash
+narratio run --session-id 2026-04-04
+```
+
+3. Read success output:
+- `narratio run: session <session_id>; executed=<n> skipped=<n>; manifest=<path>`
+- use `manifest=<path>` with `status` for inspection.
+
+Notes:
+- default config/session discovery applies unless `--config` and `--session` are passed.
+- S3 audio mode requires `session.inputs.audio_s3.prefix` and valid object-store access.
+
+## 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 restore --session-id 2026-04-04 --dry-run
+```
+
+Execution:
+
+```bash
+narratio restore --session-id 2026-04-04
+```
+
+Post-restore analyze rerun pattern:
+
+```bash
+narratio run-stage --session-id 2026-04-04 --force analyze
+```
+
+Restore source-of-truth:
+- remote commit marker: `current/run_id.txt`
+- remote current manifest: `current/manifest.json`
+
+Restore default scope:
+- includes `manifest.json`, `transcripts/**`, `artifacts/**`
+- includes `audio/**` only with `--include-audio`
+- excludes `runs/**`, `logs/**`, `reports/**`, `config/**`, `inputs/**`, and `current/**` (except remote `current/manifest.json` as source)
+
+## 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.
+
+Canonical session directories:
+- `inputs/`
+- `audio/`
+- `transcripts/`
+- `artifacts/`
+- `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`, and `run-stage analyze`.
+- filters analyze execution only; does not force stage rerun.
+
+## Remote archive layout and publish contract
+
+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.
+
+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.
+
+## 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`.
+
+Safe rerun pattern:
+1. rerun the changed stage with `--force`.
+2. run `resume` to rebuild downstream stages.
+
+## Cleanup behavior
+
+Cleanup is considered only when archive stage executed and succeeded.
+
+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.
+
+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 status --manifest <manifest-path>
+```
+
+2. for restore-specific checks, run:
+
+```bash
+narratio restore --session-id 2026-04-04 --dry-run
+```
+
+3. fix root cause (config/input/credentials/storage/service availability).
+4. continue with `resume`, or targeted `run-stage --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
+
+- `status` requires explicit `--manifest`; there is no session-id lookup command.
+- local and S3 audio input modes are mutually exclusive.
+- archive publish requires upstream stages through `analyze` to be `succeeded`.
+- required promotion rules can fail when selected analyze artifacts did not generate a required file path.
+- restore requires configured remote object storage and committed remote current state.

+# Roadmap: `narratio restore` Subcommand
+
+## Status
+
+Implemented through Step 8. This document remains as roadmap and design history for the restore feature, and as the home for future restore-related ideas (for example `run --restore`).
+
+## Summary
+
+Add a new `narratio restore` subcommand that hydrates a local session workspace from the current committed remote archive state.
+
+The primary operator workflow is:
+
+```bash
+narratio restore --session-id 2026-04-04
+narratio run-stage --force analyze
+```
+
+This should allow a new machine with no local workspace state to restore the durable session manifest, transcripts, and generated artifacts from S3, then generate new Scriptorium artifacts without re-running transcription, merge, normalize, polish, or trim.
+
+This is intentionally a separate command. Do not fold this behavior into the `prepare` stage. The existing `prepare` stage should remain focused on materializing configured local/S3 inputs for a pipeline run.
+
+## Goals
+
+- Add a first-class `narratio restore` command.
+- Restore the current committed remote session state into the canonical local session workspace.
+- Use the existing object storage adapter boundary.
+- Preserve archive commit semantics: only restore from a remote state that has a valid current commit marker.
+- Restore durable session-level outputs needed for downstream stages, especially `analyze`.
+- Provide safe conflict behavior by default.
+- Support `--dry-run`, `--force`, and `--include-audio`.
+- Keep the implementation explicit, testable, and narrow.
+
+## Non-goals
+
+- Do not make `restore` a pipeline stage.
+- Do not change the `prepare` stage behavior as part of this work.
+- Do not add implicit restore behavior to `narratio run` in this implementation.
+- Do not restore historical run-local sandboxes by default.
+- Do not implement a generic remote synchronization engine.
+- Do not implement bidirectional sync.
+- Do not delete local files merely because they are absent remotely.
+- Do not merge remote and local manifests in the first implementation.
+- Do not require live S3 for the ordinary unit test suite.
+
+## Future work explicitly out of scope
+
+A future change may add:
+
+```bash
+narratio run --restore
+```
+
+That future flag should run `narratio restore` before starting the normal pipeline. Mention this as future work in roadmap/docs if useful, but do not implement it now.
+
+## Existing architecture to preserve
+
+### `prepare` remains input materialization
+
+The `prepare` stage currently materializes required session inputs into canonical local workspace paths and records input provenance. It owns local copying/materialization of config and audio inputs, including S3 audio download when `session.inputs.audio_s3.prefix` is configured. It does not own transcript generation/processing or archive publish behavior.
+
+`restore` should not be implemented by expanding `prepare`. It should be an app-level command that reuses shared helpers where appropriate.
+
+### Workspace model
+
+The local durable session workspace is campaign-aware:
+
+```text
+{workspace.root}/work/{campaign}/{session_id}/
+```
+
+It contains durable session paths such as:
+
+```text
+manifest.json
+inputs/
+audio/
+transcripts/
+artifacts/
+reports/
+logs/
+config/
+current/
+runs/
+```
+
+Run-local sandboxes live below:
+
+```text
+runs/{run_id}/
+```
+
+Restore should target durable session-level paths, not old run-local stage sandboxes.
+
+### Storage boundary
+
+The storage adapter owns object-store primitives only: `List`, `Download`, `Upload`, and `Exists`.
+
+The storage adapter must not infer root prefixes, campaign names, session IDs, run IDs, or archive layout. Restore code must construct full bucket-relative keys before calling storage.
+
+### Archive commit boundary
+
+A remote run is current only after the archive stage has uploaded the run record, 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.
+
+Restore must not treat incomplete, skipped, failed, or uncommitted archive attempts as current remote state.
+
+## User-facing command
+
+Add:
+
+```bash
+narratio restore [flags]
+```
+
+The command should use the same configuration/session discovery conventions as `run`, `plan`, `resume`, and `run-stage` where practical:
+
+```bash
+narratio restore --config /path/to/pipeline.yml --session ./session.yml --session-id 2026-04-04
+```
+
+Required effective inputs:
+
+- resolved pipeline config;
+- resolved session config;
+- `session.campaign`;
+- `session.session_id`;
+- configured remote storage backend.
+
+Supported flags:
+
+```text
+--config <path>       Existing pipeline config path behavior.
+--session <path>      Existing session config path behavior.
+--session-id <value>  Existing session template behavior.
+--dry-run             Plan restore actions without writing local files.
+--force               Overwrite conflicting local files with remote files.
+--include-audio       Include archived session-level audio files.
+```
+
+Do not add `--restore` to `run` in this implementation.
+
+## Default restore scope
+
+By default, restore:
+
+1. Validates and reads the current remote commit marker.
+2. Downloads the current remote manifest into the local session manifest path.
+3. Downloads durable transcript files.
+4. Downloads durable generated artifact files.
+
+Default included remote/local durable paths:
+
+```text
+manifest.json                 from remote current manifest
+transcripts/**
+artifacts/**
+```
+
+Default excluded paths:
+
+```text
+audio/**                      unless --include-audio is passed
+runs/**                       always excluded for this implementation
+logs/**                       excluded for this implementation
+reports/**                    excluded for this implementation unless needed for current manifest validation
+config/**                     excluded for this implementation
+inputs/**                     excluded for this implementation
+current/**                    remote control metadata only; do not mirror blindly
+```
+
+If the existing archive implementation stores promoted files in a different remote layout, use the existing archive/path helpers and current archive semantics rather than inventing a parallel layout.
+
+## Remote state discovery
+
+Implement restore around the current committed archive state.
+
+Expected algorithm:
+
+1. Resolve pipeline/session config.
+2. Ensure storage is configured.
+3. Ensure local workspace layout exists.
+4. Acquire the session lock.
+5. Build the remote session archive prefix using the same helpers/policy used by archive code.
+6. Check for the remote `current/run_id.txt` commit marker.
+7. Read the committed run ID.
+8. Download `current/manifest.json` to a temporary file.
+9. Validate that the manifest is parseable and belongs to the requested campaign/session.
+10. Build a restore plan from the committed remote state.
+11. Execute the restore plan unless `--dry-run` is set.
+12. Emit a concise summary.
+
+Important: `current/run_id.txt` is the commit marker. Do not restore from a remote session prefix merely because files exist under `transcripts/` or `artifacts/`.
+
+## Restore planning
+
+Create a planning layer before writing files.
+
+A restore plan entry should include at least:
+
+```go
+type RestoreAction struct {
+    Kind        RestoreActionKind
+    RemoteKey   string
+    LocalPath   string
+    Size        int64
+    ETag        string
+    ExistsLocal bool
+    SameLocal   bool
+    Conflict    bool
+    Reason      string
+}
+```
+
+Suggested action kinds:
+
+```text
+download
+skip_same
+skip_missing_optional
+conflict
+```
+
+The restore planner should be deterministic:
+
+- sort remote objects by key;
+- sort planned actions by local path or stable restore priority;
+- write/report stable output for tests.
+
+## Conflict and overwrite policy
+
+Default behavior should be safe.
+
+For each planned file:
+
+```text
+local absent:
+  download
+
+local present and same as remote:
+  skip
+
+local present and different:
+  conflict; fail restore unless --force is set
+
+--force:
+  overwrite local conflicting files with remote versions
+
+--dry-run:
+  do not write any files; report what would happen
+```
+
+The first implementation may use size and checksum/hash comparison where available. If remote ETag cannot be treated as a content hash, compare by downloading to a temporary file and hashing locally before deciding whether a local file is the same. Prefer correctness over assuming provider-specific ETag semantics.
+
+Do not delete local files that are not present remotely.
+
+## File writing and transactionality
+
+Restore should avoid partial writes.
+
+Implementation requirements:
+
+- download each remote object to a temporary file under the session workspace or OS temp dir;
+- validate downloaded content where possible before replacing local files;
+- create parent directories as needed;
+- atomically rename/copy into place only after successful download;
+- do not overwrite local files unless `--force` is set;
+- if a later file fails, preserve already-restored files but return a failure summary;
+- never corrupt an existing local manifest on failed manifest download/parse.
+
+Manifest restore is especially sensitive:
+
+- download remote `current/manifest.json` to a temporary file;
+- parse and validate it;
+- if no local manifest exists, install it;
+- if a local manifest exists and is equivalent, skip;
+- if a local manifest exists and differs, fail unless `--force` is set;
+- with `--force`, replace the local manifest with the remote manifest after validation;
+- do not attempt a manifest merge in the initial implementation.
+
+## Manifest semantics
+
+`restore` is not a pipeline run and should not mark stages as running/succeeded/failed.
+
+The restored remote manifest becomes the local session manifest. That is what allows a subsequent command such as:
+
+```bash
+narratio run-stage --force analyze
+```
+
+to see existing upstream stage state and canonical durable outputs.
+
+Do not create a new run manifest for `restore`.
+
+It is acceptable to write a restore diagnostic report outside the manifest, for example:
+
+```text
+reports/restore-latest.json
+```
+
+or a timestamped report, if that pattern fits the existing codebase. The report must not contain secrets.
+
+## Local workspace locking
+
+`restore` should acquire the same session lock used by ordinary pipeline operations before modifying session workspace state.
+
+If the lock is held, fail fast with the same lock-conflict behavior used elsewhere.
+
+`--dry-run` may still acquire the lock for consistency, but it is acceptable to avoid the lock if the codebase already has a clear read-only command pattern. Prefer safety and simplicity.
+
+## Audio behavior
+
+By default, do not restore audio.
+
+If `--include-audio` is passed:
+
+- restore archived durable session-level audio files only;
+- do not use run-scoped spool paths;
+- do not mutate or delete spool state;
+- do not infer original `session.inputs.audio_s3.prefix` behavior;
+- respect the same conflict/force/dry-run behavior used for transcripts/artifacts.
+
+If the archive does not contain durable audio files, `--include-audio` should report that no archived audio was found rather than failing, unless the final implementation chooses to treat explicit audio restore as required. Prefer non-failure for absent archived audio unless tests or existing archive semantics suggest otherwise.
+
+## Remote object selection
+
+Prefer using manifest/artifact metadata when it reliably identifies durable outputs.
+
+Also support listing committed durable archive prefixes so restore can retrieve all top-level session artifacts that may not yet be fully represented in manifest metadata.
+
+The implementation should inspect existing archive code before choosing the final object-selection method. Do not duplicate archive path construction.
+
+Recommended selection priority:
+
+1. Remote current manifest path.
+2. Durable promoted transcript/artifact outputs recorded in the manifest or archive metadata, if available.
+3. Objects under committed durable `transcripts/` and `artifacts/` archive prefixes.
+4. Objects under durable `audio/` only when `--include-audio` is passed.
+
+Always exclude:
+
+```text
+runs/**
+```
+
+for the first implementation.
+
+## Package and file organization
+
+Expected areas to inspect and update:
+
+```text
+cmd/narratio/
+internal/app/
+internal/adapters/storage/
+internal/artifacts/
+internal/manifest/
+docs/
+examples/
+```
+
+Suggested implementation shape:
+
+```text
+internal/app/restore.go
+internal/app/restore_test.go
+
+internal/archive/restore/
+  planner.go
+  executor.go
+  report.go
+  keys.go
+  *_test.go
+```
+
+The exact package name may vary. Use whatever best fits the existing repository, but keep these boundaries clear:
+
+- `internal/app` owns CLI command handling, config/session loading, lock acquisition, and wiring.
+- Restore planning/execution owns remote key discovery, conflict detection, downloads, and reporting.
+- `internal/adapters/storage` remains a transport boundary only.
+- Workspace/path helpers remain centralized; do not scatter string concatenation.
+
+If the repository already has an `internal/archive` or archive-stage helper package, prefer extending that rather than creating a conflicting package layout.
+
+## CLI output
+
+`narratio restore` should print a concise operator summary.
+
+Example successful output:
+
+```text
+Restored session archive for sample-campaign/2026-04-04
+Remote run: 20260504T031500Z-a1b2c3
+Downloaded: 4
+Skipped unchanged: 2
+Conflicts: 0
+```
+
+Example dry run:
+
+```text
+Restore plan for sample-campaign/2026-04-04
+Remote run: 20260504T031500Z-a1b2c3
+Would download: transcripts/processed.json
+Would download: transcripts/trimmed.json
+Would skip unchanged: artifacts/session_recap.md
+```
+
+Example conflict:
+
+```text
+restore conflict: local artifacts/session_recap.md differs from remote archive; rerun with --force to overwrite
+```
+
+Do not print transcript or artifact content.
+
+## Error behavior
+
+Fail clearly when:
+
+- storage backend is not configured;
+- S3 bucket/config is missing or invalid;
+- remote current commit marker is missing;
+- remote current manifest is missing;
+- remote manifest is invalid;
+- remote manifest does not match requested campaign/session;
+- local file differs from remote and `--force` is not set;
+- a required remote object download fails;
+- a local path would escape the session workspace;
+- a remote key maps to an unsafe local path.
+
+Skip or report non-fatal conditions when:
+
+- optional audio restore finds no archived audio;
+- an included prefix has no objects;
+- a local file already matches the remote file.
+
+## Path safety
+
+Every restored file must map to a safe path under the session root.
+
+Validation rules:
+
+- local restore paths must be relative to the session root;
+- reject absolute paths;
+- reject `..` traversal;
+- reject paths that escape through symlinks if the codebase has symlink-safe path checks;
+- do not restore remote keys directly without mapping/classification;
+- do not mirror arbitrary remote keys.
+
+## Testing plan
+
+Add focused unit tests. Do not require live S3.
+
+### CLI tests
+
+Add or update `internal/app` command tests for:
+
+- `narratio restore --help`;
+- restore accepts `--config`, `--session`, and `--session-id`;
+- restore accepts `--dry-run`;
+- restore accepts `--force`;
+- restore accepts `--include-audio`;
+- restore fails when storage is not configured;
+- restore does not run pipeline stages.
+
+### Restore planner tests
+
+Test:
+
+- missing `current/run_id.txt` fails;
+- missing `current/manifest.json` fails;
+- invalid manifest fails;
+- wrong campaign/session manifest fails;
+- default scope includes manifest/transcripts/artifacts;
+- default scope excludes audio/logs/reports/config/runs;
+- `--include-audio` includes durable audio;
+- run-local keys are excluded;
+- keys are sorted deterministically;
+- unsafe remote-to-local paths are rejected.
+
+### Conflict policy tests
+
+Test:
+
+- absent local file downloads;
+- matching local file skips;
+- differing local file conflicts by default;
+- `--force` overwrites conflicts;
+- `--dry-run` writes nothing;
+- partial failure does not corrupt an existing local manifest.
+
+### Storage/fake tests
+
+Use fake storage to simulate:
+
+- object listing;
+- object download;
+- missing objects;
+- download failures;
+- metadata/ETag behavior.
+
+### Workspace/lock tests
+
+Test:
+
+- session layout is created before restore;
+- session lock conflict fails;
+- restored files land under the expected campaign/session workspace;
+- no files are written outside the session root.
+
+### Follow-up command workflow test
+
+Add at least one test that simulates:
+
+```bash
+narratio restore --session-id 2026-04-04
+narratio run-stage --force analyze
+```
+
+The test does not need to run real Scriptorium. Use existing fake/stub behavior to verify that restored transcripts and manifest state are sufficient for analyze-stage input resolution.
+
+## Documentation updates when implemented
+
+When the feature is implemented, update current-behavior docs:
+
+```text
+docs/cli.md
+docs/operations.md
+docs/internal/storage.md or docs/internal/archive/restore.md
+```
+
+If the documentation set does not yet have an internal restore document, add one consistent with the existing internal-doc style:
+
+```text
+docs/internal/command-restore.md
+```
+
+or:
+
+```text
+docs/internal/archive-restore.md
+```
+
+Do not document future `narratio run --restore` behavior outside `docs/roadmap/` until implemented.
+
+## Implementation phases
+
+### Phase 1: Audit existing archive and path helpers (completed)
+
+Before coding behavior, inspect:
+
+```text
+internal/app/
+internal/stage/archive*
+internal/adapters/storage/
+internal/artifacts/
+internal/manifest/
+docs/internal/stage-archive.md, if present
+```
+
+Determine:
+
+- exact remote archive key layout;
+- how root prefix/campaign/session are modeled;
+- how current commit marker keys are built;
+- how current manifest is uploaded;
+- where promoted outputs are uploaded;
+- whether helper functions already exist for remote archive keys;
+- whether local workspace path helpers can safely map restore destinations.
+
+Deliverable:
+
+- small code comments or internal helper selection;
+- no large behavior change yet unless required by tests.
+
+### Phase 2: Add CLI surface and command wiring (completed)
+
+Add `narratio restore` command parsing.
+
+Wire flags:
+
+```text
+--config
+--session
+--session-id
+--dry-run
+--force
+--include-audio
+```
+
+Use the existing config/session load path where practical.
+
+Deliverable:
+
+- command exists;
+- help output is sensible;
+- command validates basic inputs;
+- command returns a clear “not yet implemented” or calls an empty planner if phased commits are desired;
+- CLI tests pass.
+
+### Phase 3: Implement remote current-state discovery (completed)
+
+Add restore code that:
+
+- creates an object store from resolved config;
+- builds remote current marker key;
+- reads `current/run_id.txt`;
+- reads/downloads `current/manifest.json`;
+- validates manifest identity;
+- returns remote current-state metadata.
+
+Deliverable:
+
+- fake-storage tests for current-state discovery;
+- no local file writes beyond temporary files.
+
+### Phase 4: Implement restore planning (completed)
+
+Build deterministic restore plans for default scope and `--include-audio`.
+
+Deliverable:
+
+- plan lists manifest, transcript, artifact files;
+- plan excludes run-local data;
+- plan detects local same/conflict/missing states;
+- dry-run output works;
+- no real file overwrite yet except temp comparisons as needed.
+
+### Phase 5: Implement restore execution (completed)
+
+Execute the plan safely:
+
+- create directories;
+- download to temporary files;
+- validate content where practical;
+- atomically install files;
+- enforce default conflict failure;
+- support `--force`;
+- preserve existing manifest unless safe to replace.
+
+Deliverable:
+
+- restore works end-to-end against fake storage;
+- failures are clear and do not corrupt existing local manifest.
+
+### Phase 6: Add restore report and operator summary (completed)
+
+Add concise stdout summary and optional JSON restore report if consistent with project diagnostics.
+
+Deliverable:
+
+- user-friendly output;
+- durable diagnostic report if implemented;
+- no content leakage.
+
+### Phase 7: Workflow integration test (completed)
+
+Add a test for restoring a previous session and then forcing `analyze`.
+
+Deliverable:
+
+- restored manifest/transcripts/artifacts are sufficient for analyze input resolution;
+- no upstream stages rerun;
+- no reliance on live subprocesses or S3.
+
+### Phase 8: Documentation update (completed)
+
+Once implemented, update current-behavior docs and internal command docs.
+
+Also leave future `narratio run --restore` in roadmap only.
+
+## Definition of done
+
+The feature is complete when:
+
+- `narratio restore` exists and is documented.
+- It uses the same config/session discovery semantics as other commands where practical.
+- It requires configured remote storage.
+- It restores only from a committed current archive state.
+- It restores the current manifest, transcripts, and artifacts by default.
+- It restores audio only with `--include-audio`.
+- It excludes run-local sandboxes.
+- It fails on local/remote conflicts by default.
+- `--force` overwrites conflicts.
+- `--dry-run` writes nothing.
+- It uses fake storage in tests.
+- It does not change `prepare` behavior.
+- It does not implement `narratio run --restore`.
+- It avoids AWS SDK leakage outside the storage adapter.
+- It uses centralized path/key helpers rather than scattered string concatenation.
+- `go test ./...` passes.
+
+## Suggested test commands
+
+Run focused tests first:
+
+```bash
+go test ./internal/app -run TestExecute -v
+go test ./internal/adapters/storage -v
+go test ./internal/artifacts -v
+go test ./internal/manifest -v
+```
+
+Then run the full suite:
+
+```bash
+go test ./...
+```
+
+## Suggested commit message
+
+```text
+Add restore subcommand roadmap
+```

-# Archive Storage
-
-This document describes implemented archive-stage publish behavior.
-
-## S3 Paths
-
-Session root:
-
-`{root_prefix}/campaigns/{campaign}/sessions/{session_id}/`
-
-Run prefix:
-
-`{root_prefix}/campaigns/{campaign}/sessions/{session_id}/runs/{run_id}/`
-
-## Scope
-
-Implemented:
-
-- archive uploads successful run records to remote object storage through the storage backend abstraction.
-- archive uploads configured promoted outputs to session-level keys.
-- archive uploads `current/manifest.json`.
-- archive uploads `current/run_id.txt` last as the effective commit marker.
-- optional post-archive local cleanup:
-  - `pipeline.spool.delete_audio_after_archive: true` removes only the run-scoped spool audio directory
-  - `pipeline.workspace.cleanup_after_archive: true` removes only the run-scoped local workdir
-- tests use fake storage and do not require live S3.
-
-Future work:
-
-- `notify` stage behavior
-- stale detection
-- optional future source-audio upload mode
-- additional artifact generation beyond current implemented set
-
-## Prerequisites
-
-Archive verifies these stages succeeded before upload:
-
-- `prepare`
-- `transcribe`
-- `merge`
-- `polish`
-- `normalize`
-- `trim`
-- `analyze`
-
-If any prerequisite is missing or not succeeded, archive fails and does not upload.
-Failed or incomplete runs remain local only.
-
-## Run Upload
-
-Archive uploads existing files from the run workdir when present:
-
-- `inputs/`
-- `transcripts/`
-- `artifacts/`
-- `reports/` (optional)
-- `config/`
-- `logs/`
-- `manifest.json`
-
-Relative paths are preserved under `runs/{run_id}/`.
-
-## Promotion Rules
-
-Archive applies `archive.promote_artifacts` in config order.
-
-Rule behavior:
-
-- `from`: local workdir-relative source path
-- `to`: session-root-relative destination key
-- `required: true`: missing source fails archive
-- `required: false`: missing source is skipped and recorded
-
-Default promoted outputs:
-
-- `transcripts/trimmed.json`
-- `artifacts/session_recap.md`
-
-## Current Pointers
-
-Archive writes:
-
-1. `current/manifest.json` (after run upload + promotions)
-2. `current/run_id.txt` last
-
-`current/run_id.txt` contains exactly:
-
-- `{run_id}` plus trailing newline
-
-Writing `current/run_id.txt` last makes it the effective commit marker for published session state.
-
-If any required run upload, promotion upload, or current-manifest upload fails, archive returns failure and does not write `current/run_id.txt`.
-Cleanup runs only after this commit-marker write has succeeded.
-
-## Audio Upload Policy
-
-Archive does not upload local `audio/` by default.
-Original audio is expected at the session-level audio prefix and is not duplicated under `runs/{run_id}/`.
-
-## Config Controls
-
-- `archive.enabled: false` skips archive cleanly.
-- `archive.upload_run: false` skips run upload cleanly.
-- both skip cases also skip post-archive local cleanup.
-
-## Metadata
-
-Archive stage metadata includes non-secret upload context (for example):
-
-- `s3_bucket`
-- `s3_run_prefix`
-- run upload counts/paths
-- promoted upload counts/paths
-- skipped optional promotions
-- `current_manifest_key`
-- `current_run_id_key`
-- `current_pointer_written`
-- `audio_upload_skipped`

-# S3 Audio Input
-
-This document describes implemented S3 audio input behavior in `prepare`.
-
-## Scope
-
-Implemented:
-
-- `prepare` can acquire source audio from S3 when `session.inputs.audio_s3.prefix` is configured.
-- object listing and download go through the storage backend abstraction.
-- tests use fake storage; no live S3 service is required for test runs.
-
-Not implemented:
-
-- uploads of failed runs
-
-## Required Configuration
-
-`pipeline.yml`:
-
-- `storage.s3.bucket` must be set when S3 audio input is used.
-- `storage.s3.root_prefix` defaults to `dnd`.
-- `storage.s3.access_key_id_env` defaults to `OBJECT_STORAGE_KEY_ID`.
-- `storage.s3.secret_access_key_env` defaults to `OBJECT_STORAGE_KEY`.
-- `spool.root` defaults to `/var/spool/narratio`.
-
-`session.yml`:
-
-- configure `session.campaign` and `session.session_id`.
-- configure `session.inputs.audio_s3.prefix` for S3 audio input.
-- do not configure `inputs.audio_dir` or `inputs.audio_files` at the same time as `inputs.audio_s3`.
-
-## Prefix Shape
-
-Session S3 root:
-
-`{root_prefix}/campaigns/{campaign}/sessions/{session_id}/`
-
-Audio prefix:
-
-`{session_root}/{audio_s3.prefix}`
-
-Example:
-
-`dnd/campaigns/forsaken/sessions/2026-04-19/audio/`
-
-Audio files must already exist in S3 before running Narratio.
-
-## Prepare Behavior
-
-When `inputs.audio_s3.prefix` is configured, `prepare`:
-
-1. lists objects under the computed S3 audio prefix
-2. filters to `.flac` objects
-3. fails when no `.flac` objects are found
-4. downloads selected objects to spool audio:
-   - `{spool.root}/{campaign}/{session_id}/{run_id}/audio/`
-5. materializes audio into workdir audio:
-   - `{workspace.root}/work/{campaign}/{session_id}/runs/{run_id}/audio/`
-6. records input provenance in the manifest (bucket, key, metadata, local paths, checksum)
-
-Notes:
-
-- `.flac` filtering is case-insensitive.
-- ETag is recorded as provider metadata only and is not treated as a checksum.
-
-## Local Audio Development
-
-Local audio workflows remain supported:
-
-- `inputs.audio_dir`
-- `inputs.audio_files`
-
-These options are mutually exclusive with `inputs.audio_s3`.
-
-## Archive Boundary
-
-Current archive behavior relevant to S3 audio input:
-
-- successful runs are uploaded by archive under `runs/{run_id}/`
-- configured promotions are uploaded to session-level destinations
-- `current/manifest.json` and `current/run_id.txt` are published
-- local source audio is not re-uploaded by default
-- failed or incomplete runs are not uploaded

+# Troubleshooting
+
+## Purpose
+Canonical operator troubleshooting guide for recurring implemented Narratio failures.
+
+## Config file discovery failure
+
+Symptom:
+- `run`, `plan`, `resume`, `run-stage`, or `restore` fails with config/session not found.
+
+Likely Cause:
+- `pipeline.yml` or `session.yml` is missing from discovery paths.
+- wrong working directory when relying on `./session.yml`.
+
+Diagnostics:
+
+```bash
+pwd
+ls -l ./session.yml
+ls -l /usr/local/etc/narratio/pipeline.yml /etc/narratio/pipeline.yml
+```
+
+Safe Fix:
+- pass explicit `--config` and `--session`.
+- or place files in documented discovery paths.
+
+Links:
+- [docs/config.md](./config.md)
+- [docs/cli.md](./cli.md)
+
+## Session template rendering failure
+
+Symptom:
+- load fails with unresolved placeholder or `session_id` mismatch.
+
+Likely Cause:
+- templated `session.yml` used without `--session-id`.
+- rendered `session_id` differs from passed `--session-id`.
+
+Diagnostics:
+
+```bash
+narratio plan --session ./session.yml --session-id 2026-04-04
+```
+
+Safe Fix:
+- pass `--session-id` when template placeholders are present.
+- ensure rendered `session_id` matches intended run session id.
+
+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 plan --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04
+```
+
+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 --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --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 non-analyze stage
+
+Symptom:
+- `run-stage` fails with `--artifacts is only supported for stage "analyze"`.
+
+Likely Cause:
+- `--artifacts` was used with a non-`analyze` stage.
+
+Diagnostics:
+
+```bash
+narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --artifacts session_recap polish
+```
+
+Safe Fix:
+- use `--artifacts` only with `run-stage ... analyze`.
+
+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 plan --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04
+```
+
+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 status --manifest /path/to/manifest.json
+narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --artifacts player_handout analyze
+```
+
+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:
+- `status` fails because manifest path is missing, unreadable, or invalid.
+
+Likely Cause:
+- wrong manifest path.
+- manifest removed after cleanup.
+- `--manifest` omitted.
+
+Diagnostics:
+
+```bash
+narratio status --manifest /path/to/manifest.json
+ls -l /path/to/manifest.json
+```
+
+Safe Fix:
+- use manifest path printed by `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 `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:
+- `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 restore --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --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:
+- `restore` fails because remote manifest session or campaign does not match requested values.
+
+Likely Cause:
+- wrong `--session-id` or wrong session config selected.
+- archive prefix points to a different campaign/session.
+
+Diagnostics:
+
+```bash
+narratio restore --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --dry-run
+```
+
+Safe Fix:
+- use the correct session config and `--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:
+- `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 restore --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --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 --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 prepare
+```
+
+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 status --manifest /path/to/manifest.json
+narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 archive
+```
+
+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.
+
+Links:
