-# Roadmap: Code Quality and Deduplication Audit
-
-Status: Draft audit report
-
-This is a pre-1.0 implementation audit. It identifies remaining high-confidence opportunities to simplify, centralize, or clarify Narratio before release. It is report-only: no code refactors are included here.
-
-The current repository keeps architecture and development policy under `docs/policy/`, not at `docs/architecture.md` or `docs/development.md`. This audit used `docs/policy/architecture.md`, `docs/policy/development.md`, `docs/policy/documentation.md`, the current user/operator docs, the internal docs, code, examples, and tests.
-
-## 1. Executive Summary
-
-Overall code quality is strong. Narratio now has clear package boundaries in the important places:
-
-- configuration loading is strict and centralized enough for current commands;
-- object-store construction is app-owned and secret-aware;
-- storage adapters do not infer campaign/session/run semantics;
-- S3 key construction and local workspace paths are mostly centralized in `internal/artifacts`;
-- artifact source vocabulary has a dedicated `internal/artifactpolicy` package;
-- remote current-state loading is centralized in `internal/artifacts`;
-- cleanup path safety and temp object downloads have shared helpers;
-- publish terminology has replaced the old archive/promote surface in live code.
-
-There is no major architectural risk and no reason to delay 1.0 for a broad rewrite. The remaining opportunities are targeted cleanup items where a future bug fix could otherwise need changes in several files.
-
-Top three refactoring targets before 1.0:
-
-1. Finish consolidating artifact source policy for Scriptorium inputs and previous-session candidates.
-2. Centralize session-relative path conversion and atomic file install/copy mechanics.
-3. Extract a small read-only inspection/preflight layer used by `session validate` and `session status`.
-
-The codebase is ready for a limited cleanup pass. Avoid speculative abstractions.
-
-## 2. High-Confidence Deduplication Opportunities
-
-### Complete Artifact Source Policy for Scriptorium Inputs
-
-Affected files/packages:
-
-- `internal/artifactpolicy`
-- `internal/config/validate.go`
-- `internal/stage/analyze.go`
-- `internal/artifacts/artifact_resolver.go`
-- `internal/previouscache/previouscache.go`
-- tests under `internal/config`, `internal/stage`, `internal/artifacts`, and `internal/previouscache`
-
-Duplicated or near-duplicated behavior:
-
-- `artifactpolicy.ClassifySource` knows built-in, configured, and previous-session source families.
-- `config.validateScriptoriumInputSource` still implements Scriptorium-input-specific validation, including previous-session source parsing, configured artifact lookups, and static built-in checks.
-- `stage.resolveScriptoriumInput` classifies sources, then maps missing configured/previous/built-in sources to stage-specific required/optional behavior.
-- `previouscache.artifactRelativePathCandidates` reconstructs previous-session artifact candidates from manifest outputs, published paths, and configured output paths.
-- `artifacts.ResolveSessionArtifactWithCatalog` and `ResolvePreviousSessionArtifactWithCatalog` own runtime resolution, but caller-side policy still reaches into source details.
-
-Why it matters:
-
-Artifact source IDs are public configuration. They are used by Scriptorium inputs, previous-session inputs, publish outputs, locks, status, artifacts listing, restore, and validation. `internal/artifactpolicy` solved much of this, but Scriptorium input validation and previous-session candidate derivation still contain source-vocabulary logic outside the policy layer.
-
-Recommended refactor:
-
-Extend `internal/artifactpolicy` with narrow Scriptorium-input helpers, not a generic artifact engine:
-
-- `ValidateScriptoriumInputSource(source, configuredKeys)` returning a classified source plus any referenced configured artifact key.
-- a shared helper for "is this source a built-in runtime input source?"
-- a small previous-session source descriptor used by config validation, previous-cache planning, and analyze resolution.
-
-Keep missing/required behavior at call sites. For example, `analyze` should still decide whether a missing optional input is skipped or a missing required input fails with prepare guidance.
-
-Suggested tests:
-
-- `internal/artifactpolicy`: valid/invalid Scriptorium input sources, previous-session source format, unknown configured references.
-- `internal/config`: Scriptorium input validation still reports field-specific errors.
-- `internal/stage`: analyze required/optional source behavior unchanged.
-- `internal/previouscache`: previous-session requirements and candidate ordering unchanged.
-
-Risk level: Medium. This touches public config validation, but the existing tests are good and the policy surface can remain small.
-
-### Centralize Session-Relative Path Conversion and Safe Local Install Mechanics
-
-Affected files/packages:
-
-- `internal/app/restore_plan.go`
-- `internal/app/restore_execute.go`
-- `internal/stage/run_local.go`
-- `internal/stage/prepare.go`
-- `internal/previouscache/previouscache.go`
-- `internal/artifacts/local.go`
-- `internal/audio/s3_audio.go`
-- `internal/manifest/store.go`
-- `internal/pathsafe`
-
-Duplicated or near-duplicated behavior:
-
-- `restore_plan.joinWithinSessionRoot` validates session-relative restore targets.
-- `previouscache.relativeToSession`, `deriveManifestRelativePath`, and `manifestSessionRoot` convert local manifest paths back into session-relative paths.
-- `stage.runLocalPathForCanonical` validates that canonical outputs stay within a session root and skips `previous/**`.
-- `artifacts.resolveInRoot` validates relative paths under an artifact root.
-- Atomic write/copy/install flows appear in `artifacts.LocalStore`, `audio.MaterializeS3Audio`, `restore_execute`, `manifest.LocalStore`, and `prepare` helper functions.
-
-Why it matters:
-
-These helpers are individually careful, but they all express the same safety policy: relative paths must not escape a scoped root, writes should use temp files plus rename, and cleanup should not leave partial outputs. This is exactly the kind of code where drift is costly.
-
-Recommended refactor:
-
-Add narrow helpers without moving application semantics:
-
-- in `internal/pathsafe`, add session/root helpers such as `JoinWithinRoot(root, rel)` and `RelativeWithinRoot(root, absoluteOrRelative)`;
-- add a tiny file operation helper package, or extend `artifacts.LocalStore` carefully, for atomic install/copy/write with optional checksum;
-- keep restore scope classification in `restore_plan.go`, because the include/exclude roots are command-specific.
-
-Suggested tests:
-
-- `internal/pathsafe`: root escape, absolute path rejection, Windows-style separators, empty paths, valid session-relative joins.
-- `internal/app`: restore conflict/force behavior unchanged.
-- `internal/stage`: run-local materialization paths unchanged.
-- `internal/audio`: cache hit/miss behavior unchanged.
-- `internal/manifest`: atomic manifest save behavior unchanged.
-
-Risk level: Low to Medium. The mechanics are well-contained, but file writes are sensitive and should be protected by focused tests.
-
-### Extract Shared Read-Only Session Inspection Checks
-
-Affected files/packages:
-
-- `internal/app/operator_findings.go`
-- `internal/app/operator_session_validate.go`
-- `internal/app/operator_status.go`
-- `internal/stage/prepare.go`
-- `internal/previouscache/previouscache.go`
-- `internal/audio`
-- `internal/artifacts/current_state.go`
-
-Duplicated or near-duplicated behavior:
-
-- `session validate` resolves stable input paths and checks files in a way that mirrors prepare.
-- `session validate` checks local audio or remote audio by listing S3 audio objects, while prepare has the materialization path and restore has audio cache materialization.
-- `session validate` checks previous-session current state, while previous-cache planning performs a deeper check and restore uses `previouscache.BuildPlan`.
-- `status` independently loads local manifest state, remote current state, effective locks, and published output state.
-
-Why it matters:
-
-These commands are read-only, so divergence does not corrupt state. But operator trust depends on them matching runtime behavior. If validate says a session is ready while prepare would fail, or status reports a remote condition differently from restore, operators get confusing guidance.
-
-Recommended refactor:
-
-Create a small app-level inspection layer, not a workflow engine:
-
-- one helper for resolved stable-input file checks;
-- one helper for audio presence checks that mirrors prepare's selection rules without downloading bodies;
-- one helper that can run previous-cache planning in a "metadata only / no body download" mode where possible;
-- one helper result type that status and validate can render differently.
-
-Do not move output formatting into this layer. Keep command-specific text in `internal/app`.
-
-Suggested tests:
-
-- `internal/app`: validate/status agree on local vs remote audio state.
-- `internal/app`: previous-session missing current pointer/manifest is rendered consistently.
-- `internal/previouscache`: optional and required previous inputs keep existing behavior.
-- `internal/stage`: prepare behavior remains the authority for actual materialization.
-
-Risk level: Medium. The semantic differences between status, validate, prepare, and restore are intentional in places, so the helper should centralize checks, not command policy.
-
-### Atomic File Operation Helpers Are Repeated
-
-Affected files/packages:
-
-- `internal/artifacts/local.go`
-- `internal/audio/s3_audio.go`
-- `internal/app/restore_execute.go`
-- `internal/manifest/store.go`
-- `internal/stage/prepare.go`
-
-Duplicated or near-duplicated behavior:
-
-- create parent directory;
-- create sibling temp file;
-- copy/write bytes;
-- sync/close;
-- chmod;
-- rename;
-- remove temp file on failure;
-- sometimes compute SHA-256 while copying.
-
-Why it matters:
-
-The duplication is not large, but these are correctness-sensitive operations. A future hardening change, such as more consistent `fsync`, permissions, or Windows behavior, would need repeated edits.
-
-Recommended refactor:
-
-Add a small dependency-light file helper, for example `internal/fileops`, with:
-
-- `WriteAtomic(path, data, perm, pattern)`;
-- `CopyAtomic(src, dst, perm)`;
-- `CopyAtomicWithSHA256(src, dst, perm)`;
-- `InstallDownloadedTemp(tmp, dst, perm)`.
-
-Keep manifest JSON marshaling, audio cache policy, restore plan policy, and artifact store semantics in their existing packages.
-
-Suggested tests:
-
-- temp file removed on write/copy failure;
-- destination parent creation;
-- checksum from copy matches final file;
-- restore and audio cache tests continue to pass.
-
-Risk level: Low. This is mechanical but should be done in a small commit.
-
-## 3. Medium-Confidence Opportunities
-
-### CLI Parsing Is Mostly Centralized, With Intentional Special Cases
-
-Affected files/packages:
-
-- `internal/app/session_args.go`
-- `internal/app/operator_helpers.go`
-- `internal/app/run.go`
-- `internal/app/resume.go`
-- `internal/app/run_stage.go`
-- `internal/app/operator_locks.go`
-- `internal/app/restore.go`
-
-Current state:
-
-Common config flags and session ID matching are centralized enough for 1.0. `run-stage`, `locks add`, and `locks remove` still do command-specific positional parsing because they have extra positional arguments.
-
-Recommended refactor:
-
-Do not introduce a CLI framework. If another session command is added, consider a small parser helper for "session id plus one additional positional argument" so `locks add/remove` and any future similar commands share the same mismatch behavior.
-
-Suggested tests:
-
-- existing session-oriented CLI tests;
-- positional session ID plus `--session-id` mismatch;
-- missing extra positional source for locks add/remove.
-
-Risk level: Low.
-
-### Restore Scope Mapping Should Probably Stay Local
-
-Affected files/packages:
-
-- `internal/app/restore_plan.go`
-- `docs/internal/command-restore.md`
-
-Current state:
-
-Restore maps remote keys back to local paths and intentionally includes only `manifest.json`, `transcripts/**`, `artifacts/**`, and optionally `audio/**`. It explicitly excludes current pointers, run history, logs, reports, configs, inputs, and current-session `previous/**`.
-
-Why it is not a high-priority refactor:
-
-This policy is restore-specific. Generalizing it too much would obscure the command contract.
-
-Recommended refactor:
-
-Leave it local unless restore gains another caller. If it grows, extract only the classifier into a table-driven helper with tests.
-
-Risk level: Low.
-
-### Command Output Formatting Is Intentionally Text-Local
-
-Affected files/packages:
-
-- `internal/app/operator_findings.go`
-- `internal/app/operator_artifact_rendering.go`
-- `internal/app/operator_locks.go`
-- `internal/app/restore_report.go`
-- `internal/app/clean.go`
-- `internal/app/plan.go`
-
-Current state:
-
-Each command renders plain text directly. Validation-style findings share a small renderer. Artifact list/status share artifact rendering.
-
-Recommended refactor:
-
-Do not add a generic renderer before 1.0. Add focused helper functions only if a user-facing inconsistency is found.
-
-Risk level: Low.
-
-### Manifest Transition Logic Is Dense but Correctly Centralized
-
-Affected files/packages:
-
-- `internal/app/runner.go`
-- `internal/manifest`
-
-Current state:
-
-The runner owns manifest/run-manifest lifecycle, stage transitions, downstream stale marking, and post-publish cleanup gating. The function is long, but it is one explicit orchestration path.
-
-Recommended refactor:
-
-Avoid a broad manifest abstraction. If desired after 1.0, extract tiny helpers for repeated save/error wrapping inside the runner only.
-
-Risk level: Low.
-
-## 4. Boundary and Responsibility Concerns
-
-Healthy boundaries:
-
-- `internal/adapters/storage` exposes only `ObjectStore`; AWS SDK types stay inside the S3 backend.
-- App code owns secret loading and object-store initialization.
-- `internal/artifacts` owns local path and S3 key helpers.
-- `internal/artifactpolicy` owns most public source vocabulary.
-- `internal/audio` owns S3 audio cache materialization.
-- Stage code remains explicit and adapter-facing.
-
-Boundary concerns:
-
-- Scriptorium input source validation still lives partly in `internal/config` instead of fully using source policy.
-- Previous-cache candidate selection mixes manifest interpretation, publish metadata, and configured artifact output paths in `internal/previouscache`; this is defensible but should share source descriptors with artifact policy.
-- Read-only operator checks mirror stage behavior in `internal/app`; if they grow, they should move into a small inspection layer rather than further expanding command handlers.
-- File operation mechanics are repeated across packages; a narrow helper would clarify that write safety is shared mechanics, not stage policy.
-
-Recommended homes:
-
-- source vocabulary and validation: `internal/artifactpolicy`;
-- concrete runtime artifact lookup: `internal/artifacts`;
-- remote current-state mechanics: `internal/artifacts`;
-- command orchestration and rendering: `internal/app`;
-- file write mechanics: a small dependency-light helper such as `internal/fileops`, or carefully scoped methods on `artifacts.LocalStore`;
-- stage execution policy: `internal/stage`.
-
-## 5. Path and Remote Key Construction Review
-
-Remote key construction is centralized enough for 1.0:
-
-- session, run, audio, session config, locks, current-state, published output, and run-relative keys are in `internal/artifacts/s3_keys.go`;
-- storage adapters normalize object keys but do not infer Narratio semantics;
-- publish identity helpers resolve bucket/session/run/current-state identities without moving layout policy into storage.
-
-Local path construction is mostly centralized:
-
-- session roots, run roots, previous cache paths, spool paths, and S3 audio cache paths are in `internal/artifacts/paths.go`;
-- cleanup target validation is in `internal/app/cleanup_targets.go`;
-- relative publish destinations use `internal/pathsafe`.
-
-Areas worth cleanup:
-
-- session-relative conversion helpers are repeated in restore, previous-cache, run-local stage code, and artifacts local-store helpers;
-- `restore_plan.go` has local remote-key normalization, which is acceptable for restore but should not spread;
-- tests still build some S3 keys through string concatenation when fixture readability would not suffer from using helpers.
-
-Recommended action:
-
-Add narrow `pathsafe` helpers for "join/rel within root" and use them where they reduce escape-check duplication. Do not move restore's include/exclude scope policy out of restore unless it gains another caller.
-
-## 6. Artifact/Catalog/Source Resolution Review
-
-Current state is good:
-
-- transcript source IDs live in `internal/artifactmodel` and are exposed through `internal/artifacts`;
-- configured and previous-session source formats live in `internal/artifactpolicy`;
-- publish output destination derivation is centralized in `artifactpolicy.ResolvePublishedDestination`;
-- runtime catalog behavior is in `internal/artifacts`;
-- previous-session requirements are collected by `artifacts.CollectPreviousArtifactRequirements`.
-
-Remaining gap:
-
-`artifactpolicy` does not yet cover the full Scriptorium-input validation contract. `internal/config/validate.go` still knows too much about source parsing and built-in source support. `stage/analyze.go` still has source-family-specific missing input messages, which is appropriate, but it should be consuming a richer policy classification rather than re-checking source strings.
-
-Recommendation:
-
-Extend the policy layer one step further, but keep runtime existence checks in `internal/artifacts` and command/stage missing behavior at the call sites.
-
-## 7. Config and Command-Loading Review
-
-Config loading is consistent:
-
-- `loadCommandConfig` handles pipeline, campaign, local session discovery, remote session fallback, and session identity checks;
-- `loadPipelineCampaignConfig` correctly supports `session init`, which cannot load an existing session;
-- `newCommandObjectStore` loads secret files before constructing storage;
-- concrete-only session loading is enforced in `internal/config`.
-
-Intentional differences:
-
-- `session init` loads pipeline and campaign only.
-- `clean --all` is pipeline-scoped, not session-scoped.
-- `status`, `validate`, `artifacts`, and `locks` render command-specific output after shared loading.
-- `restore` has richer help/output behavior and therefore does slightly more local parsing setup.
-
-Likely accidental drift remaining:
-
-- small positional parsing patterns for commands with extra arguments are repeated;
-- `session validate` and `status` each decide which remote checks are warnings, errors, or status lines;
-- `loadHelperContext` is useful but not used by every helper because some commands need partial failure reporting.
-
-Recommendation:
-
-No broad loader rewrite is needed. Future command work should reuse `commonConfigFlags`, `parseSessionAwareFlags`, `loadCommandConfig`, `loadPipelineCampaignConfig`, and `newCommandObjectStore`.
-
-## 8. Refactors to Avoid Before 1.0
-
-Avoid:
-
-- a generic workflow engine or DAG abstraction;
-- a generic CLI framework;
-- broad manifest query or transition abstractions;
-- moving secret loading into storage adapters;
-- making storage adapters infer campaign/session/root-prefix semantics;
-- centralizing all command text output into a generic renderer;
-- merging audio cache materialization with generic restore downloads;
-- compatibility aliases for retired archive/promote, legacy campaign, or legacy transcript names;
-- moving restore's command-specific scope policy into storage or artifacts.
-
-These would add risk without solving current release problems.
-
-## 9. Recommended Implementation Sequence
-
-1. Add root-scoped path helpers and optional atomic file helpers.
-   - Scope: `internal/pathsafe` plus a small file helper if chosen.
-   - Tests: `internal/pathsafe`, `internal/audio`, `internal/app -run Restore`, `internal/stage -run Prepare`.
-
-2. Extend artifact source policy for Scriptorium inputs.
-   - Scope: `internal/artifactpolicy`, `internal/config/validate.go`, `internal/stage/analyze.go`, `internal/previouscache`.
-   - Tests: `internal/artifactpolicy`, `internal/config`, `internal/stage -run Analyze`, `internal/previouscache`.
-
-3. Extract read-only session inspection checks.
-   - Scope: stable inputs, audio presence, previous-session readiness, locks/current-state checks.
-   - Tests: `internal/app -run 'SessionValidate|Status'`, `internal/previouscache`, `internal/stage -run Prepare`.
-
-4. Trim command parsing edge duplication only if needed.
-   - Scope: commands with session ID plus one extra positional argument.
-   - Tests: `internal/app -run 'Session|Locks|RunStage'`.
-
-5. Final sweep.
-   - Run focused searches for retired terminology and old source names.
-   - Run the focused package tests listed below and then `go test ./...`.
-
-## 10. Test Strategy
-
-Focused checks for any cleanup work:
-
-- `go test ./internal/artifactpolicy -v`
-- `go test ./internal/artifacts -v`
-- `go test ./internal/config -v`
-- `go test ./internal/stage -run 'Analyze|Prepare|Publish' -v`
-- `go test ./internal/app -run 'SessionValidate|Status|Restore|Locks|RunStage' -v`
-- `go test ./internal/previouscache -v`
-- `go test ./internal/audio -v`
-- `go test ./internal/pathsafe -v`
-- `go test ./internal/adapters/storage -v`
-- `go test ./internal/manifest -v`
-
-Full validation after each implementation prompt:
-
-- `go test ./...`
-
-Useful final searches:
-
-- `rg -n "archive|promote|promoted|promotion" internal docs examples cmd`
-- `rg -n "narratio.transcript.merged|narratio.transcript.full|narratio.transcript.trimmed" internal docs examples`
-- `rg -n "previous_session_artifact|promote_artifacts|pipeline.archive" internal docs examples`
-- `rg -n "session_id is required|unexpected positional|--artifacts" internal/app`
-- `rg -n "CreateTemp|Rename|copyFileAtomic|WriteFileAtomic|DownloadObjectToTemp" internal`
-
-## 11. Appendix: Findings Not Worth Acting On
-
-- Restore's include/exclude scope logic should remain restore-local. It is command policy, not general path policy.
-- Direct text rendering in command handlers is acceptable. The output is text-only and command-specific by design.
-- Stage-local path joins under run-local directories are acceptable when they use established session/run roots.
-- `run-stage`, `locks add`, and `locks remove` deserve explicit positional parsing because their syntax is not identical to simple session commands.
-- The runner is long, but it is the right place for explicit stage orchestration and manifest transitions.
-- `session init` template rendering should remain separate from ordinary concrete session loading.
-- S3 audio cache materialization is intentionally special and should not be folded into generic object download logic.

-# Roadmap: Pre-1.0 Code Cleanup
-
-Status: Planned
-
-This roadmap turns the remaining findings in `docs/roadmap/audit.md` into decision-complete implementation stages. It follows the policy documents under `docs/policy/` and preserves current public CLI, config, storage layout, manifest, and stage behavior unless a stage explicitly says otherwise.
-
-## Goals
-
-- Reduce repeated path, file, source-policy, and read-only inspection logic before 1.0.
-- Keep Narratio explicit, stage-driven, and easy to review.
-- Keep storage adapters free of campaign/session/run/root-prefix semantics.
-- Keep command output text-only and command-specific.
-- Keep implementation changes small enough for focused prompts and focused tests.
-
-## Non-Goals
-
-- Do not introduce a generic workflow engine or DAG abstraction.
-- Do not introduce a generic CLI framework.
-- Do not introduce a broad manifest abstraction.
-- Do not move secret loading into storage adapters.
-- Do not make storage adapters infer Narratio path or key semantics.
-- Do not add compatibility aliases for retired archive/promote, campaign, transcript, or previous-session source names.
-- Do not move restore's remote-key include/exclude policy out of restore unless another caller is added.
-
-## Stage 1: Path and File Mechanics
-
-Add shared mechanics for root-scoped path safety and atomic file operations.
-
-Implementation decisions:
-
-- Add root-scoped helpers in `internal/pathsafe`:
-  - join a slash-style relative path safely under a root;
-  - derive a safe slash-style relative path from a path under a root;
-  - reject empty paths, absolute paths, traversal, and paths outside the root.
-- Add a small dependency-light `internal/fileops` package for shared file installation mechanics:
-  - atomic byte write;
-  - atomic file copy;
-  - atomic file copy with SHA-256 checksum;
-  - install an already-downloaded temp file with permissions.
-- Prefer `internal/fileops` over extending `artifacts.LocalStore`, because the same mechanics are used by app, stage, audio, artifacts, and manifest code.
-- Keep higher-level semantics local:
-  - restore decides which remote keys are in scope;
-  - audio decides cache hit/miss behavior;
-  - manifest decides JSON marshaling and validation;
-  - stages decide canonical output materialization.
-
-Implementation targets:
-
-- Replace duplicate root-escape checks in restore planning, run-local output handling, previous-cache path conversion, and artifact local path helpers where doing so keeps behavior identical.
-- Replace duplicate temp-write/copy/rename mechanics in artifact local store, audio cache materialization, restore execution, and prepare helpers where the call site can keep its current error context.
-- Leave manifest save behavior unchanged if sharing it would obscure manifest-specific validation or error text.
-
-Tests:
-
-- `go test ./internal/pathsafe -v`
-- `go test ./internal/audio -v`
-- `go test ./internal/app -run Restore -v`
-- `go test ./internal/stage -run Prepare -v`
-- `go test ./...`
-
-Acceptance criteria:
-
-- Root escape, absolute path, empty path, Windows separator, and valid relative path cases are covered by path-safe tests.
-- Atomic helper tests prove temp files are cleaned up on failure and checksums match final file contents.
-- Restore, prepare, and audio cache behavior remain unchanged.
-
-## Stage 2: Artifact Source Policy
-
-Finish centralizing artifact source vocabulary and validation in `internal/artifactpolicy`.
-
-Implementation decisions:
-
-- Extend `internal/artifactpolicy` with Scriptorium-input policy helpers:
-  - classify and validate built-in, configured, and previous-session source IDs;
-  - validate referenced configured artifact keys against the configured artifact set;
-  - expose a previous-session source descriptor for callers that need the configured artifact key.
-- Keep runtime artifact lookup in `internal/artifacts`.
-- Keep missing, required, optional, and operator-guidance behavior at call sites:
-  - config validation still produces field-specific errors;
-  - analyze still decides whether missing inputs fail or skip;
-  - previous-cache planning still decides required vs optional behavior.
-- Do not make `artifactpolicy` inspect manifests, files, object storage, or runtime catalogs.
-
-Implementation targets:
-
-- Replace source parsing and static built-in checks in config validation with artifactpolicy helpers.
-- Update analyze input resolution to consume the shared classification/descriptors while preserving current error messages and required/optional behavior.
-- Update previous-cache planning to use shared previous-session source descriptors where source vocabulary is involved.
-- Keep publish output destination derivation through `artifactpolicy.ResolvePublishedDestination`.
-
-Tests:
-
-- `go test ./internal/artifactpolicy -v`
-- `go test ./internal/config -v`
-- `go test ./internal/stage -run Analyze -v`
-- `go test ./internal/previouscache -v`
-- `go test ./...`
-
-Acceptance criteria:
-
-- Valid Scriptorium input source cases pass through one shared policy path.
-- Invalid source format and unknown configured artifact references keep clear config-field errors.
-- Analyze behavior for required/optional built-in, configured, and previous-session sources is unchanged.
-- Previous-cache candidate ordering and required/optional behavior are unchanged.
-
-## Stage 3: Read-Only Inspection Layer
-
-Extract shared read-only session inspection checks for `session validate` and `session status`.
-
-Implementation decisions:
-
-- Keep the new inspection helpers in `internal/app`; they are command orchestration helpers, not stage or storage adapter behavior.
-- Create small result types for checks, but do not create a generic reporting framework.
-- Keep command-specific rendering local:
-  - `session validate` renders findings and fails on `ERROR`;
-  - `session status` renders state and does not fail for missing local/remote state unless config loading fails.
-- Do not download artifact bodies for inspection unless current behavior already does so.
-
-Implementation targets:
-
-- Extract stable input checks from `operator_findings.go` into a reusable inspection helper.
-- Extract local and remote audio presence checks that mirror prepare's selection rules without materializing audio.
-- Extract previous-session readiness checks using existing current-state and previous-cache planning mechanics where possible.
-- Extract effective lock and remote current-state inspection into reusable command helpers.
-- Keep artifact catalog rendering separate from these checks.
-
-Tests:
-
-- `go test ./internal/app -run 'SessionValidate|Status' -v`
-- `go test ./internal/previouscache -v`
-- `go test ./internal/stage -run Prepare -v`
-- `go test ./...`
-
-Acceptance criteria:
-
-- `session validate` and `session status` agree on local/remote audio and previous-session readiness facts.
-- Missing current run pointer/manifest behavior remains command-appropriate: validation reports an error; status reports unavailable state.
-- Existing lock and remote current-state behavior is unchanged.
-
-## Stage 4: Optional CLI Edge Cleanup
-
-Only implement this stage if Stage 1-3 leave meaningful repeated parser code.
-
-Implementation decisions:
-
-- Add at most one small parser helper for commands with `session_id` plus one additional positional argument.
-- Use it for `session locks add` and `session locks remove` if it reduces duplication without obscuring syntax.
-- Keep command handlers explicit.
-- Do not change public syntax, flag names, help text meaning, or error semantics.
-
-Tests:
-
-- `go test ./internal/app -run 'Session|Locks|RunStage' -v`
-- `go test ./...`
-
-Acceptance criteria:
-
-- Positional `session_id` and `--session-id` mismatch errors remain unchanged.
-- Missing source arguments for lock add/remove remain clear.
-- No new command aliases are introduced.
-
-## Stage 5: Final Sweep
-
-Run final validation after the implementation stages.
-
-Required searches:
-
-- `rg -n "archive|promote|promoted|promotion" internal docs examples cmd`
-- `rg -n "narratio.transcript.merged|narratio.transcript.full|narratio.transcript.trimmed" internal docs examples`
-- `rg -n "previous_session_artifact|promote_artifacts|pipeline.archive" internal docs examples`
-- `rg -n "CreateTemp|Rename|copyFileAtomic|WriteFileAtomic|DownloadObjectToTemp" internal`
-
-Expected search results:
-
-- Retired terminology should remain only where intentionally historical or where fixture names make it unrelated to current behavior.
-- Old transcript and old config/source names should not appear in runtime code, tests, examples, or current-behavior docs.
-- File-operation searches should show centralized helpers plus acceptable direct uses where package-specific behavior remains intentional.
-
-Required tests:
-
-- `go test ./internal/artifactpolicy -v`
-- `go test ./internal/artifacts -v`
-- `go test ./internal/config -v`
-- `go test ./internal/stage -run 'Analyze|Prepare|Publish' -v`
-- `go test ./internal/app -run 'SessionValidate|Status|Restore|Locks|RunStage' -v`
-- `go test ./internal/previouscache -v`
-- `go test ./internal/audio -v`
-- `go test ./internal/pathsafe -v`
-- `go test ./internal/adapters/storage -v`
-- `go test ./internal/manifest -v`
-- `go test ./...`
-
-Roadmap cleanup:
-
-- Mark each completed stage as implemented only after its code, tests, and any internal docs are updated.
-- Keep this file as planned work until the implementation stages land.
-- Do not update canonical user/operator docs unless implementation changes visible behavior, which this roadmap does not intend.
-
-## Assumptions
-
-- Public CLI and config behavior remains unchanged throughout this cleanup.
-- `internal/fileops` is the preferred home for shared atomic file mechanics.
-- `internal/artifactpolicy` remains the source-policy home.
-- `internal/artifacts` remains the path/key/current-state home.
-- `internal/app` remains the command-loading, inspection, and rendering home.
-- Stage packages keep stage execution policy and adapter interaction.
