 ## Shortest Useful Command
 
 ```bash
-narratio run --session-id 2026-04-04
+narratio run 2026-04-04
 ```
 
-This command uses default config discovery for `pipeline.yml` and `session.yml`; both files must be discoverable unless you pass explicit `--config` and `--session` paths.
+This command uses default system discovery for `pipeline.yml`, the pipeline default campaign ID, and local `session.yml`. If local session discovery misses and S3 storage is configured, the positional session ID loads remote `session.yml` from the canonical session prefix.
+
+Default pipeline and session discovery checks system config locations only. Pass `--config`, `--campaign-file`, and `--session` to use files from the current working directory. Pass `--campaign <id>` to select a campaign from `pipeline.campaigns.root`.
+
+Ordinary local and remote `session.yml` files must be concrete YAML. Templates belong to `narratio session init`, which renders a configured campaign template before writing the concrete file.

-## Complete Flag Reference
+## Common Flags
+
+Most session-aware commands accept:
+
+- `--config <path>`: optional explicit `pipeline.yml` path.
+- `--campaign <id>`: optional campaign ID selector.
+- `--campaign-file <path>`: optional explicit `campaign.yml` path.
+- `--session <path>`: optional explicit concrete `session.yml` path.
+- `--previous-session-id <value>`: expected previous session identifier.
+
+The positional `<session_id>` is required even when `--session` is provided. It is used as the expected session identity and as the remote session lookup value when local session discovery misses.

+- the contents of `{spool.root}`, while preserving the spool root directory itself.
+
+Cache behavior:
+- cache is preserved by default.
+- `--clear-cache` in session mode removes cached S3 audio files for the resolved session.
+- `--all --clear-cache` removes the configured Narratio S3 audio cache namespace for the configured bucket/root prefix.
+- `--clear-cache` does not delete arbitrary files under `pipeline.cache.root`.
+
+### `session plan`
+
+```bash
+narratio session plan <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--force]
+```
+
+Purpose:
+- Validate config, load secrets if configured, prepare workdir, and print stage run/skip decisions.
+
+Success output includes:
+- `narratio session plan: workdir prepared at <path>`
+- one line per stage (`<stage>: run|skip`)
+- `totals: run=<n> skip=<n>`
+
+### `session status`
+
+```bash
+narratio session status <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+```
+
+Output includes:
+- session ID, campaign, workspace, and session config source.
+- local manifest state when present.
+- remote current archive state when storage is configured.
+- catalog-based promoted output availability for expected transcript and artifact sources.
+- effective archive locks and conservative next actions.
+
+### `session validate`
+
+```bash
+narratio session validate <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+```
+
+Checks include:
+- effective config and session source.
+- stable input files.
+- local or remote audio availability.
+- previous-session requirements.
+- archive promotions and effective locks.
+
+Warnings do not fail the command. Any `ERROR` finding exits non-zero.
+
+### `session init`
+
+```bash
+narratio session init <session_id> --output ./session.yml
+narratio session init <session_id> --remote
+narratio session init <session_id> --config <pipeline.yml> --campaign icewind --remote
+narratio session init <session_id> --config <pipeline.yml> --campaign-file ./campaign.yml --remote
+```
+
+Additional flags:
+
+- `--previous-session-id <value>`
+- `--date <value>`
+- `--title <value>`
+- `--audio-s3-prefix <prefix>`: defaults to `audio/` when neither audio flag is provided.
+- `--audio-dir <path>`: local audio directory; mutually exclusive with `--audio-s3-prefix`.
+- `--force`: overwrite existing local or remote target.
+
+Behavior:
+- exactly one of `--output` or `--remote` is required.
+- `--config`, `--campaign`, and `--campaign-file` are optional overrides; omitted campaign selection uses `pipeline.campaigns.default_campaign_id`.
+- `--campaign <id>` selects a campaign under `pipeline.campaigns.root`.
+- `--campaign-file <path>` loads an explicit campaign file.
+- if `campaign.yml` sets `session_template_file`, the template path is resolved relative to `campaign.yml` and rendered from init flags.
+- if no session template is configured, a minimal concrete session file is generated directly.
+- template variables must be supplied by matching flags, and supplied template-related flags must be used by the template.
+- remote writes target `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/session.yml`.
+- existing local or remote targets fail unless `--force` is passed.
+- remote writes use existence checks, not compare-and-swap.
+
+### `session restore`
+
+```bash
+narratio session restore <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--dry-run] [--force] [--include-audio]
+```
+
+Purpose:
+- Restore durable session state from the committed remote archive current state.
+- Default restore installs `manifest.json`, `transcripts/**`, and `artifacts/**` from the current session archive.
+- When configured previous-session inputs require it, restore reconstructs `previous/**` from the previous session's committed current archive.
+- `audio/**` is restored only with `--include-audio`.
+
+Dry-run output may include planned previous-cache downloads. Existing differing files under `previous/**` follow the normal restore conflict policy and require `--force` to overwrite.
+
+When `--include-audio` is set, S3 audio files are restored through the shared audio cache. Cache hits avoid re-downloading large audio objects.
+
+### `session artifacts`
+
+```bash
+narratio session artifacts <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--remote]
+```
+
+Purpose:
+- List built-in, configured, previous-session, promoted, and locked artifact sources.
+
+`--remote` checks promoted top-level object availability through the storage adapter. Remote markers appear only in the `Promoted` section, which reports each configured archive promotion destination and includes `dest=<path>` when that destination differs from the source's canonical path.
+
+### `session locks`
+
+```bash
+narratio session locks <session_id> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+narratio session locks add <session_id> <source> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>] [--reason <text>] [--force]
+narratio session locks remove <session_id> <source> [--config <pipeline.yml>] [--campaign <id>] [--campaign-file <campaign.yml>] [--session <session.yml>] [--previous-session-id <id>]
+```
+
+Behavior:
+- list mode prints effective locks from static `pipeline.archive.locks` and remote `{session_prefix}/locks.yml`.
+- `locks add` writes only the remote lock store and fails if the source is already locked by pipeline config.
+- `locks remove` removes only remote locks and cannot remove static pipeline locks.
+- `locks add --force` is required to update an existing remote lock reason.

-  - `{{session_id}}`
+
+Template behavior for local and remote `session.yml` loaded by downstream commands:
+
+- downstream commands do not render templates.
+- local and remote `session.yml` must be concrete.

   - `{{ session_id }}`
-- `--session-id <value>` supplies the placeholder value.

 # Internal: Artifacts
 
 ## Purpose
-Define Narratio's artifact identity and resolution model for built-in transcript/bounds artifacts and runtime-configured analyze artifacts.
+Define Narratio artifact identity, catalog, and source-resolution behavior for:
+- built-in session artifacts;
+- configured analyze artifacts;
+- canonical previous-session artifact sources.
 
 ## Inputs and outputs
 Inputs:
-- artifact sources from config/runtime (`pipeline.scriptorium.artifacts.*.inputs.*.source`)
+- configured input sources (`pipeline.scriptorium.artifacts.*.inputs.*.source`);
-- session paths and optional session manifest stage outputs
+- session paths and manifest inputs/outputs;
-- runtime artifact catalog state for configured artifact sources
+- runtime catalog state.
 
 Outputs:
-- resolved local artifact path and provenance (`ResolvedSessionArtifact`)
+- resolved artifact path + provenance (`ResolvedSessionArtifact`);
-- runtime catalog entries for planned/executable/available artifacts
+- runtime catalog entries for built-ins and configured artifacts;
-- validation errors for unsupported, missing, or invalid artifact sources
+- requirement sets for canonical previous-session inputs.
+- canonical S3 session, run, current, session config, session locks, audio, and promoted artifact keys.
 
 ## Boundaries
 Owns:
-- built-in artifact registry and content validation rules
+- built-in source registry and validation;
-- runtime artifact catalog for configured artifact source IDs
+- configured artifact catalog identity (`narratio.artifact.<name>`);
-- source resolution behavior for built-in and configured artifact sources
+- canonical previous-session source parsing and resolution;
+- previous-session requirement collection (`CollectPreviousArtifactRequirements`).
 
 Does not own:
-- artifact generation (stages produce files)
+- prepare-stage remote hydration;
-- manifest transition policy
+- stage success/skip transitions;
-- archive promotion behavior
+- archive upload orchestration.

-Runtime catalog entries include built-ins and configured `narratio.artifact.<name>` sources.
+## Source families
+- built-in: `narratio.transcript.*`, `narratio.bounds.session`
+- configured artifact: `narratio.artifact.<artifact_key>`
+- canonical previous-session artifact: `narratio.previous_session.artifact.<artifact_key>`
 
-Catalog states:
+## S3 key helpers
-- `planned`: source is registered and known for this run
+- session prefix: `{root_prefix}/campaigns/{campaign}/sessions/{session_id}/`
-- `executable`: configured artifact is selected for analyze execution
+- session config: `{session_prefix}/session.yml`
-- `available`: artifact has a usable file path (generated this run or reused from disk)
+- session lock store: `{session_prefix}/locks.yml`
+- run prefix: `{session_prefix}/runs/{run_id}/`
+- audio prefix: `{session_prefix}/{session.inputs.audio_s3.prefix}`
+- current manifest: `{session_prefix}/current/manifest.json`
+- current run pointer: `{session_prefix}/current/run_id.txt`
 
-Resolution behavior:
+## Runtime catalog model
-- built-in sources resolve via manifest producer outputs first, then canonical fallback path
+Catalog entries track:
-- configured `narratio.artifact.<name>` sources resolve through runtime catalog availability
+- `planned`: source is registered for this run;
-- configured source lookup requires catalog context
+- `executable`: configured artifact is selected for analyze execution;
+- `available`: usable local file exists (generated this run or reused from disk).
 
-Configured artifact provenance values:
+Configured artifact provenance values include:
 - `generated.current_analyze_run`
 - `filesystem.disabled_artifact_output`
 
-Content validation:
+Previous-session canonical provenance values include:
-- transcript built-ins: JSON with top-level `segments` array
+- `manifest.inputs.previous_cache`
-- bounds built-in: valid JSON
+- `current_session.previous_cache`
-- configured artifacts: non-empty text file
 
-## Skip and resume behavior
+## Resolution behavior
-- resolver and catalog have no direct skip/resume decisions
+- Built-ins resolve via manifest producer outputs first, then canonical fallback paths.
-- stage/runner skip-resume behavior consumes catalog/resolver results
+- Configured `narratio.artifact.<name>` sources resolve through catalog availability.
+- Canonical previous-session sources resolve to current-session `previous/` cache candidates derived from configured artifact canonical output paths.
+- Archive-relative configured artifact paths under `artifacts/` are cached without a redundant nested `artifacts/` segment.
+- Previous-session canonical resolution prefers manifest-recorded input paths when present, then filesystem fallback under `previous/artifacts/**`.
+
+## Previous-session requirement scanning
+`CollectPreviousArtifactRequirements`:
+- scans enabled configured artifacts only;
+- includes canonical previous-session sources only;
+- deduplicates by artifact key;
+- merges required/optional references (`required` wins);
+- records deterministic sorted source locations for diagnostics.
+
+## Validation behavior
+- transcript built-ins: JSON with top-level `segments` array;
+- bounds built-in: valid JSON;
+- configured and previous-session artifact files: non-empty text content.
 
 ## Failure behavior
-- unsupported source -> source validation error
+- unsupported source or malformed canonical previous source: validation/resolution error;
-- known source unavailable -> `ErrSessionArtifactNotFound`
+- known source unavailable: `ErrSessionArtifactNotFound`;
-- configured source without catalog -> resolution error
+- configured/previous canonical source without catalog: error;
-- resolved file with invalid content -> validation error

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

+- `internal/app/restore_test.go`
+- `internal/app/restore_discovery_test.go`
+- `internal/app/restore_plan_test.go`
+- `internal/app/restore_execution_test.go`
+- `internal/app/restore_workflow_test.go`
+- `internal/artifacts/archive_identity_test.go`
+
+## Architectural invariants
+- Restore relies on centralized archive identity/key helpers (`internal/artifacts`) rather than ad hoc key building.
+- `current/run_id.txt` is the remote commit marker; restore must not infer committed state from incidental files.
+- Local path mapping is traversal-safe and constrained to session root.
+- Restore scope is deterministic and path-classified:
+  - include `manifest.json`, `transcripts/**`, `artifacts/**`, `previous/**`
+  - include `audio/**` only with `--include-audio`
+  - exclude `runs/**`, `logs/**`, `reports/**`, `config/**`, `inputs/**`
+- Command remains standalone; no implicit `run --restore` behavior.

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

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

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

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

-# Roadmap: Runtime-Defined Scriptorium Artifacts
-
-## Status
-
-Implementation roadmap for a pre-release hard cutover.
-
-## Purpose
-
-Narratio currently treats artifact generation as a narrow `analyze` stage that supports a hard-coded `session_recap` artifact. This roadmap describes how to generalize artifact generation so operators can define Scriptorium-backed output artifacts at runtime through `pipeline.yml`.
-
-The goal is to keep Narratio as a fixed pipeline orchestrator while making the artifact generation step configurable, composable, deterministic, and easy to regenerate selectively.
-
-## Desired Outcome
-
-Operators should be able to define artifacts such as session recaps, player handouts, NPC summaries, quest logs, entity maps, or other campaign-specific outputs without changing Narratio code.
-
-A configured artifact is declared under:
-
-```text
-pipeline.scriptorium.artifacts.<name>
-```
-
-Each configured artifact becomes a canonical runtime artifact source ID:
-
-```text
-narratio.artifact.<name>
-```
-
-For example:
-
-```yaml
-scriptorium:
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: dnd_session.session_recap
-      output_path: artifacts/session_recap.md
-      inputs:
-        transcript:
-          source: narratio.transcript.trimmed
-          required: true
-```
-
-This artifact is addressable by later artifacts as:
-
-```text
-narratio.artifact.session_recap
-```
-
-A dependent artifact can then consume it explicitly:
-
-```yaml
-scriptorium:
-  artifacts:
-    player_handout:
-      enabled: true
-      depends_on:
-        - session_recap
-      prompt_id: dnd_session.player_handout
-      output_path: artifacts/player_handout.md
-      inputs:
-        recap:
-          source: narratio.artifact.session_recap
-          required: true
-        transcript:
-          source: narratio.transcript.trimmed
-          required: true
-```
-
-## Resolved Design Decisions
-
-The following decisions are settled for the initial implementation:
-
-1. Configured artifact outputs must live under Narratio's internal artifact output directory, initially `artifacts/`.
-2. The artifact output directory should be defined as an internal default in `internal/config/defaults.go`, but no public configuration knob should be exposed yet.
-3. Artifact `output_path` should remain explicit in the initial implementation to avoid guessing file extensions or output formats.
-4. A disabled artifact may still be referenced as an input if its declared output already exists on disk and passes basic validation.
-5. A disabled artifact is not executable during the current analyze run.
-6. Artifact-to-artifact references require an explicit `depends_on` entry. Narratio should fail fast if the dependency declaration is missing.
-7. The manifest remains stage-oriented: `analyze` succeeds or fails as a full stage.
-8. Analyze-stage metadata may record per-artifact output details for provenance and later resolution, but not for intra-stage resume semantics.
-9. `--artifacts` should be added as a CLI filter for selective artifact generation.
-10. `--artifacts` does not imply `--force`; it only changes which configured artifacts are treated as executable when `analyze` actually runs.
-11. Because Narratio is still pre-release, the hard-coded `session_recap` behavior should be removed immediately rather than deprecated gradually.
-
-## Scope
-
-This roadmap covers:
-
-- introducing a runtime artifact catalog;
-- generalizing configured Scriptorium artifact execution;
-- supporting `narratio.artifact.<name>` source IDs;
-- adding explicit artifact dependencies;
-- supporting disabled-but-resolvable artifact inputs;
-- adding selective artifact execution via `--artifacts`;
-- recording generated artifacts in analyze-stage metadata and/or manifest outputs;
-- removing hard-coded `session_recap` behavior;
-- updating tests and documentation.
-
-## Non-Goals
-
-This feature should not turn Narratio into a general workflow engine.
-
-The initial implementation should not add:
-
-- arbitrary shell-command artifacts;
-- arbitrary user-defined stages;
-- loops or conditional branching;
-- automatic archive promotion of generated artifacts;
-- semantic knowledge of particular artifact types;
-- per-artifact resume semantics within a successful or failed analyze stage;
-- automatic dependency inference without `depends_on`.
-
-Narratio should continue to orchestrate a fixed pipeline. The configurable part is the set of Scriptorium artifact invocations performed during the `analyze` stage.
-
-## Current State
-
-Narratio already has several relevant pieces in place:
-
-- `pipeline.scriptorium.artifacts` is modeled as a map of artifact definitions.
-- The Scriptorium adapter already accepts generic run/render requests.
-- The artifact resolver already understands canonical artifact source IDs.
-- The `analyze` stage already resolves inputs, optionally runs render-debug, invokes Scriptorium, verifies output, and records metadata.
-
-The main limitation is that `analyze` currently treats `session_recap` as the only executable artifact and rejects other enabled artifact definitions.
-
-## Target Architecture
-
-### Runtime Artifact Catalog
-
-Introduce a per-run artifact catalog that tracks built-in artifacts and configured artifacts.
-
-Conceptually:
-
-```text
-ArtifactCatalog
-├── built-in artifacts
-│   ├── narratio.transcript.merged
-│   ├── narratio.transcript.polished
-│   ├── narratio.transcript.full
-│   ├── narratio.transcript.trimmed
-│   └── narratio.bounds.session
-│
-└── configured artifacts
-    ├── narratio.artifact.session_recap
-    ├── narratio.artifact.player_handout
-    └── narratio.artifact.npc_summary
-```
-
-The catalog should distinguish between three states:
-
-```text
-planned       valid configured or built-in artifact known to Narratio
-available     artifact has been produced or otherwise resolved
-executable    configured artifact selected for execution in this analyze run
-```
-
-Configured artifacts can be planned without being executable. This distinction is important for disabled artifacts and for `--artifacts` filtering.
-
-### Configured Artifact Source IDs
-
-Configured artifact keys map directly to source IDs:
-
-```text
-pipeline.scriptorium.artifacts.<name>
-→ narratio.artifact.<name>
-```
-
-`session_recap` should no longer be a special built-in analyze artifact. Instead, it is just a conventional configured artifact key:
-
-```yaml
-scriptorium:
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: dnd_session.session_recap
-      output_path: artifacts/session_recap.md
-```
-
-`narratio.artifact.session_recap` remains valid only because `session_recap` is configured.
-
-### Artifact Output Directory
-
-Add an internal default artifact output directory, initially:
-
-```text
-artifacts
-```
-
-This default should live in `internal/config/defaults.go` or the existing equivalent defaults location.
-
-For the initial implementation:
-
-- expose no public config knob for the artifact output directory;
-- require each configured artifact to provide an explicit `output_path`;
-- validate that each configured artifact `output_path` is run-relative;
-- validate that each configured artifact `output_path` is under the internal artifact output directory;
-- reject output paths that escape the run workspace or use path traversal.
-
-This preserves future configurability without forcing Narratio to guess output extensions or formats now.
-
-### Enabled, Disabled, and Selected Artifacts
-
-Configured artifacts should have three distinct execution states:
-
-```text
-enabled by config       artifact has enabled: true
-selected for execution  artifact remains executable after --artifacts filtering
-disabled for execution  artifact is not executable, but may be resolvable from disk
-```
-
-Without `--artifacts`, all configured artifacts with `enabled: true` are selected for execution.
-
-With `--artifacts`, only the named artifacts are selected for execution. All other configured artifacts are treated as disabled for the current analyze invocation, regardless of their configured `enabled` value.
-
-Disabled artifacts may still be resolved as inputs if their configured `output_path` exists on disk and passes validation.
-
-### Disabled Artifact Resolution
-
-If artifact `B` references artifact `A`, and `A` is disabled for execution, Narratio should attempt to resolve `A` from disk.
-
-This should succeed only when:
-
-1. `A` is defined in `pipeline.scriptorium.artifacts`;
-2. `A` has a valid `output_path`;
-3. the output path exists in the current run workspace;
-4. the output is non-empty, or otherwise passes any available artifact-specific validation.
-
-The resolved provenance should make the source clear, for example:
-
-```text
-filesystem.disabled_artifact_output
-```
-
-If the file does not exist or fails validation, the dependent artifact should fail before invoking Scriptorium.
-
-Example error wording:
-
-```text
-artifact player_handout requires narratio.artifact.session_recap, but session_recap is disabled for execution and artifacts/session_recap.md does not exist
-```
-
-### Explicit Dependencies
-
-Artifact-to-artifact references require explicit `depends_on` entries.
-
-If artifact `B` has an input source of `narratio.artifact.A`, then `B.depends_on` must include `A`.
-
-This should fail:
-
-```yaml
-scriptorium:
-  artifacts:
-    player_handout:
-      enabled: true
-      prompt_id: dnd_session.player_handout
-      output_path: artifacts/player_handout.md
-      inputs:
-        recap:
-          source: narratio.artifact.session_recap
-          required: true
-```
-
-This should pass:
-
-```yaml
-scriptorium:
-  artifacts:
-    player_handout:
-      enabled: true
-      depends_on:
-        - session_recap
-      prompt_id: dnd_session.player_handout
-      output_path: artifacts/player_handout.md
-      inputs:
-        recap:
-          source: narratio.artifact.session_recap
-          required: true
-```
-
-`depends_on` values refer to configured artifact keys, not full source IDs.
-
-Dependency validation should fail on:
-
-- references to unknown artifact keys;
-- missing `depends_on` entries for artifact-to-artifact input references;
-- self-dependencies;
-- dependency cycles among executable artifacts.
-
-Dependencies on disabled artifacts are permitted, but the disabled dependency must resolve from disk before the dependent artifact runs.
-
-### Execution Order
-
-The analyze stage should execute selected artifacts in dependency order.
-
-Rules:
-
-- selected artifacts are executable;
-- disabled artifacts are never executed;
-- selected artifacts may depend on other selected artifacts;
-- selected artifacts may depend on disabled artifacts if those disabled artifacts resolve from disk;
-- independent selected artifacts run in deterministic sorted-name order.
-
-Use topological sorting over selected artifacts, while validating dependency references across the full configured artifact set.
-
-### Input Resolution
-
-Input resolution should use the artifact catalog and existing artifact resolver behavior.
-
-For each configured artifact input:
-
-- built-in sources resolve through existing resolver behavior;
-- `previous_session_artifact` preserves existing behavior;
-- `narratio.artifact.<name>` resolves through the runtime artifact catalog;
-- selected dependencies resolve after being produced earlier in the same analyze execution;
-- disabled dependencies resolve from their configured output path on disk;
-- optional missing inputs are omitted;
-- required missing inputs fail before Scriptorium is invoked.
-
-### Analyze Stage Generalization
-
-The `analyze` stage should become the generic Scriptorium artifact stage.
-
-High-level flow:
-
-1. Load configured Scriptorium artifacts.
-2. Apply the `--artifacts` filter, if present.
-3. If no artifacts are selected for execution, return success metadata with `skipped=true`.
-4. Build the runtime artifact catalog.
-5. Validate artifact names, output paths, source IDs, dependencies, selected artifacts, and required fields.
-6. Resolve any disabled dependencies that are required by selected artifacts.
-7. Sort selected artifacts by dependency order.
-8. For each selected artifact:
-   - resolve configured inputs;
-   - build the Scriptorium run request;
-   - optionally run Scriptorium render-debug;
-   - run Scriptorium;
-   - fail on validation-failed result;
-   - verify the output exists and is non-empty;
-   - record artifact output metadata;
-   - register `narratio.artifact.<name>` as available in the catalog.
-9. Return aggregate analyze-stage metadata containing all generated and reused artifacts relevant to the run.
-
-The Scriptorium adapter should remain generic. It should not decide which artifacts run, how dependencies work, or how artifacts are registered.
-
-### Manifest and Metadata
-
-The manifest should remain stage-oriented.
-
-This means:
-
-- `analyze` succeeds or fails as a full stage;
-- if `analyze` has already succeeded and the user does not force it, the runner skips it as a full stage;
-- Narratio should not implement per-artifact resume in the first version.
-
-However, analyze-stage metadata should still record artifact outputs for provenance and future resolution.
-
-Recommended metadata shape:
-
-```json
-{
-  "skipped": false,
-  "artifacts": [
-    {
-      "name": "session_recap",
-      "source_id": "narratio.artifact.session_recap",
-      "output_kind": "scriptorium_artifact",
-      "path": "artifacts/session_recap.md",
-      "prompt_id": "dnd_session.session_recap",
-      "profile_id": "local-gemma-31b",
-      "provenance": "generated.current_analyze_run"
-    },
-    {
-      "name": "player_handout",
-      "source_id": "narratio.artifact.player_handout",
-      "output_kind": "scriptorium_artifact",
-      "path": "artifacts/player_handout.md",
-      "prompt_id": "dnd_session.player_handout",
-      "profile_id": "local-gemma-31b",
-      "provenance": "generated.current_analyze_run"
-    }
-  ],
-  "reused_artifacts": [
-    {
-      "name": "session_recap",
-      "source_id": "narratio.artifact.session_recap",
-      "path": "artifacts/session_recap.md",
-      "provenance": "filesystem.disabled_artifact_output"
-    }
-  ]
-}
-```
-
-The exact struct can differ from this example, but it should preserve:
-
-- artifact name;
-- canonical source ID;
-- output path;
-- prompt/profile provenance for generated artifacts;
-- reused-vs-generated provenance.
-
-### Resume and Force Behavior
-
-Keep resume behavior stage-level.
-
-Recommended semantics:
-
-```text
-No --force, analyze already succeeded:
-  runner skips analyze, regardless of --artifacts.
-
---force, no --artifacts:
-  analyze regenerates all configured artifacts with enabled: true.
-
---force --artifacts player_handout:
-  analyze treats only player_handout as executable.
-  all other configured artifacts are disabled for execution.
-  disabled dependencies may be reused from disk.
-
---artifacts player_handout on a not-yet-completed analyze stage:
-  analyze runs only player_handout.
-  disabled dependencies may be reused from disk.
-```
-
-`--artifacts` should not imply `--force`. It is an execution filter, not a resume override.
-
-### `--artifacts` CLI Flag
-
-Add an `--artifacts` flag to commands that can execute or resume the analyze stage.
-
-The flag should accept one or more configured artifact names. Internally, normalize values to a set of artifact keys.
-
-Recommended behavior:
-
-- validate all requested artifact names against `pipeline.scriptorium.artifacts`;
-- reject unknown artifact names before running stages;
-- treat requested artifacts as the only executable artifacts for the analyze stage;
-- treat all other configured artifacts as disabled for execution;
-- allow disabled artifacts to satisfy dependencies from disk as described above;
-- if `--artifacts` is used while executing a stage other than `analyze`, either reject it or ignore it with a clear validation error. Prefer rejection.
-
-The exact CLI parsing style can follow Narratio's existing conventions. Both comma-separated and repeatable values are acceptable if the CLI package supports them cleanly, but the internal representation should be a set of artifact keys.
-
-### Archive Behavior
-
-Do not automatically archive every generated artifact.
-
-Artifact generation and archive promotion should remain separate concerns. Operators should continue to use `archive.promote_artifacts` to decide which generated files should be promoted or uploaded.
-
-Example:
-
-```yaml
-archive:
-  promote_artifacts:
-    - from: artifacts/session_recap.md
-      to: artifacts/session_recap.md
-      required: true
-    - from: artifacts/player_handout.md
-      to: artifacts/player_handout.md
-      required: false
-```
-
-A later enhancement may add opt-in automatic promotion of configured artifacts, but explicit promotion should remain the default.
-
-## Implementation Plan
-
-### Phase 1: Config Model and Defaults
-
-Add or update the configured artifact model to include:
-
-- `enabled`;
-- `depends_on`;
-- `prompt_id`;
-- `profile_id`;
-- `output_path`;
-- `timeout`;
-- `render_debug`;
-- `inputs`;
-- `vars`.
-
-Add an internal default artifact output directory in `internal/config/defaults.go`, initially set to `artifacts`.
-
-Validation rules:
-
-- artifact names must match a conservative identifier pattern such as `^[a-z][a-z0-9_]*$`;
-- selected/executable artifacts require `prompt_id` and `output_path`;
-- configured artifacts that may be referenced while disabled require `output_path`;
-- configured artifact output paths must be run-relative;
-- configured artifact output paths must live under the internal artifact output directory;
-- configured artifact output paths must not escape the run workspace;
-- `narratio.artifact.<name>` input sources must refer to configured artifact keys;
-- any `narratio.artifact.<name>` input source must have a matching `depends_on` entry;
-- `depends_on` entries must refer to configured artifact keys;
-- dependencies must not contain self-references or executable cycles;
-- input names and var names must remain compatible with the Scriptorium adapter's validation rules;
-- unknown YAML fields must continue to fail strict decode.
-
-Tests:
-
-- valid single configured artifact;
-- valid multiple independent artifacts;
-- valid artifact-to-artifact dependency;
-- valid dependency on disabled artifact with output path;
-- invalid artifact name;
-- missing required fields;
-- output path outside `artifacts/`;
-- dependency on missing artifact;
-- missing `depends_on` for artifact input source;
-- self-dependency;
-- cycle detection;
-- typo in `narratio.artifact.<name>` source;
-- unknown YAML fields still fail strict decode.
-
-### Phase 2: CLI Filtering
-
-Add the `--artifacts` flag and carry the selected artifact set into the run execution options.
-
-Implementation notes:
-
-- parse values according to existing CLI conventions;
-- normalize to artifact key strings;
-- validate against configured artifact definitions after config load;
-- make the selected set available to the analyze stage;
-- reject use with commands or stages where analyze cannot run.
-
-Tests:
-
-- no `--artifacts` means all enabled artifacts are selected;
-- one requested artifact is selected;
-- multiple requested artifacts are selected;
-- unknown requested artifact fails;
-- `--artifacts` does not imply `--force`;
-- `--artifacts` with already-succeeded analyze stage is skipped unless forced;
-- `--artifacts` on unsupported stage command fails clearly.
-
-### Phase 3: Runtime Artifact Catalog
-
-Introduce an internal artifact catalog abstraction.
-
-Responsibilities:
-
-- register built-in artifact definitions;
-- register configured artifact definitions;
-- map configured artifact keys to `narratio.artifact.<name>` IDs;
-- track planned, available, and executable artifact states;
-- expose lookup by canonical source ID;
-- record generated provenance;
-- record disabled-from-disk provenance.
-
-Keep the catalog narrow. It should not execute Scriptorium and should not understand prompt semantics.
-
-Tests:
-
-- built-in source lookup;
-- configured source registration;
-- duplicate/conflicting source handling;
-- planned but unavailable artifact lookup;
-- selected artifact state;
-- disabled artifact state;
-- registering an artifact as available after generation;
-- registering a disabled artifact as available from disk;
-- resolving a configured artifact from analyze metadata if that behavior is implemented.
-
-### Phase 4: Resolver Integration
-
-Update artifact resolution so configured artifact IDs are resolved through the runtime catalog.
-
-Resolution behavior:
-
-- built-in sources continue using existing resolver behavior;
-- configured artifact sources resolve from catalog availability/provenance;
-- selected configured artifacts become available after generation;
-- disabled configured artifacts may become available from disk;
-- missing optional configured artifact inputs are omitted;
-- missing required configured artifact inputs fail clearly.
-
-Tests:
-
-- configured artifact consumes a built-in transcript source;
-- configured artifact consumes another configured artifact produced earlier in the same analyze run;
-- configured artifact consumes a disabled artifact resolved from disk;
-- required disabled artifact missing on disk fails;
-- required configured artifact missing fails;
-- optional missing configured artifact is omitted;
-- reused artifact provenance is recorded distinctly from generated artifact provenance.
-
-### Phase 5: Analyze Stage Generalization
-
-Refactor `analyze` to execute selected configured artifacts.
-
-Implementation notes:
-
-- remove the hard-coded `session_recap` selection path;
-- remove the hard-coded rejection of non-`session_recap` artifacts;
-- preserve skip behavior when Scriptorium config is absent or no artifacts are selected;
-- build the runtime artifact catalog;
-- apply `--artifacts` filtering;
-- validate selected artifacts and their dependencies;
-- pre-resolve disabled dependencies from disk where required;
-- compute deterministic dependency order;
-- execute selected artifacts one at a time in dependency order;
-- keep render-debug behavior at global and artifact levels;
-- keep Scriptorium adapter invocation generic;
-- after each successful run, register the artifact as available in the catalog;
-- aggregate generated and reused artifact metadata.
-
-Tests:
-
-- no Scriptorium config skips;
-- empty artifact map skips;
-- no selected artifacts skips;
-- disabled artifacts do not run;
-- one selected artifact runs;
-- multiple independent artifacts run in deterministic order;
-- dependent selected artifact receives prior selected artifact as input;
-- dependent selected artifact receives disabled-from-disk artifact as input;
-- render-debug works for configured artifacts;
-- Scriptorium validation failure fails the stage;
-- missing required input fails the stage;
-- successful outputs are non-empty and recorded;
-- artifact filter executes only requested artifacts.
-
-### Phase 6: Manifest and Stage Metadata
-
-Update analyze-stage metadata and manifest output recording to support dynamic configured artifacts.
-
-Recommended behavior:
-
-- every generated configured artifact gets `source_id: narratio.artifact.<name>`;
-- every generated configured artifact gets a generic output kind such as `scriptorium_artifact`;
-- reused disabled artifacts are recorded separately from generated artifacts;
-- metadata is sufficient for debugging, provenance, and future resolver support;
-- metadata does not create per-artifact resume semantics.
-
-Because this is a pre-release hard cutover, do not preserve a special legacy `session_recap` output kind unless a current internal test or archive path still requires it temporarily. Prefer updating tests and examples to treat `session_recap` as an ordinary configured artifact.
-
-Tests:
-
-- metadata records one generated configured artifact;
-- metadata records multiple generated configured artifacts;
-- metadata records reused disabled artifact provenance;
-- `session_recap` is recorded as a normal configured artifact;
-- manifest still treats `analyze` as a single succeeded or failed stage;
-- runner skip behavior remains stage-level.
-
-### Phase 7: Archive and Promotion Review
-
-Review archive behavior after dynamic artifacts are recorded.
-
-Implementation notes:
-
-- do not automatically promote every configured artifact;
-- keep `archive.promote_artifacts` explicit;
-- update default or example promotion rules to use configured `session_recap` output path;
-- ensure required promotion rules fail clearly when selected artifact generation did not produce a required file.
-
-Tests:
-
-- generated artifact can be promoted by explicit archive rule;
-- required archive promotion fails if selected artifact was not generated and no file exists;
-- optional archive promotion skips cleanly if file is absent;
-- hard cutover does not rely on hard-coded `session_recap` generation.
-
-### Phase 8: Documentation and Examples
-
-Status: complete.
-
-Update documentation after the implementation is complete.
-
-Recommended documentation changes:
-
-- update `docs/config.md` with the generalized artifact configuration model;
-- update `docs/internal/artifacts.md` to describe the runtime artifact catalog;
-- update `docs/stages/analyze.md` to describe generic Scriptorium artifact generation;
-- update Scriptorium integration docs only if the adapter contract changes;
-- update full annotated pipeline examples;
-- add at least one example with multiple artifacts and one dependency;
-- document `--artifacts` behavior and its relationship to `--force`;
-- remove documentation stating that only `session_recap` is supported.
-
-Documentation should make clear that:
-
-- configured artifact source IDs use `narratio.artifact.<name>`;
-- `depends_on` uses artifact keys, not full source IDs;
-- artifact-to-artifact source references require explicit `depends_on`;
-- disabled artifacts can be reused from disk when required by selected artifacts;
-- `--artifacts` filters execution but does not imply `--force`;
-- archive promotion remains explicit;
-- per-artifact resume is not part of the initial implementation.
-
-## Migration Strategy
-
-Because Narratio is pre-release, perform a hard cutover.
-
-Required changes:
-
-1. Remove the hard-coded `session_recap` analyze behavior.
-2. Require `session_recap` to be declared under `pipeline.scriptorium.artifacts.session_recap` if the operator wants a session recap.
-3. Treat `narratio.artifact.session_recap` as valid only when `session_recap` is a configured artifact key.
-4. Update config examples to show `session_recap` as a normal configured artifact.
-5. Update tests to stop assuming that `session_recap` is a built-in analyze artifact.
-6. Keep archive promotion explicit and path-based.
-
-Example replacement config:
-
-```yaml
-scriptorium:
-  binary: scriptorium
-  config_path: /etc/scriptorium/config.yml
-  timeout: 10m
-  render_debug: false
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: dnd_session.session_recap
-      profile_id: local-gemma-31b
-      output_path: artifacts/session_recap.md
-      timeout: 20m
-      inputs:
-        transcript:
-          source: narratio.transcript.trimmed
-          required: true
-        prior_recap:
-          source: previous_session_artifact
-          artifact: artifacts/session_recap.md
-          required: false
-      vars:
-        artifact_title: Session Recap
-```
-
-## Acceptance Criteria

-
-- operators can define more than one enabled Scriptorium artifact in `pipeline.yml`;
-- Narratio runs selected artifacts in deterministic dependency order;
-- configured artifacts are addressable as `narratio.artifact.<name>`;
-- one configured artifact can consume another configured artifact as an input;

-- tests cover config validation, dependency sorting, disabled artifact resolution, resolver behavior, CLI filtering, analyze execution, archive interactions, and metadata.

-## Suggested Implementation Order
-
-1. Config model, defaults, and validation.
-2. CLI parsing and propagation of `--artifacts` selection.
-3. Runtime artifact catalog.
-4. Resolver integration for configured artifacts.
-5. Analyze stage generalization.
-6. Stage metadata and manifest output recording.
-7. Archive behavior review.
-8. Documentation and examples.
-
-This order keeps the most static pieces first, then moves into execution behavior once the configuration contract is explicit and well tested.

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