# Codebase Audit Findings

Status: in progress

This document is the working ledger and final report for the audit defined by
the [audit plan](audit-plan.md) and [audit sequence](audit-sequence.md). The
audit is investigative: candidate findings below are not remediation changes.

## Audit Identity And Baseline

| Field | Value |
| --- | --- |
| Audited revision | `74e2d21de5fb2ada0be5ef3fe9333e0d48ac7fb3` (`Close the completed roadmap documents`) |
| Branch | `main`, attached worktree |
| Initial worktree state | Untracked `docs/roadmap/audit-plan.md` and `docs/roadmap/audit-sequence.md`; no production or test changes |
| Audit date | 2026-08-10 UTC |
| Toolchain | `go version go1.26.5 linux/amd64` |
| Platform | `GOOS=linux`, `GOARCH=amd64` |
| Repository root | `/home/eric/Workspace/narratio` |

The two initial untracked files are the audit specification supplied for this
run. Adding this ledger and tracking those documents changes documentation
only; all implementation and test evidence remains pinned to the revision
above. If implementation or tests change, affected audit stages must be rerun
and this section must record the new revision.

### Baseline Commands

| Command | Result | Wall time | Evidence or limitation |
| --- | --- | --- | --- |
| `go test -count=1 ./...` | pass | 3.34 s | All 23 packages passed; `cmd/narratio` has no test files. |
| `go test -race -count=1 ./...` | fail | 55.65 s | Race in `internal/adapters/whisperx.(*FakeClient).Transcribe` at `fake.go:45`, reached concurrently by `TestTranscribeStageTranscribesPreparedAudio`; candidate `TST-001`. All packages reported before `internal/stage` passed. |
| `go vet ./...` | pass | 0.47 s | No diagnostics. |
| `go build -o "$audit_build_dir/narratio" ./cmd/narratio` | pass | 1.03 s | Built outside the repository in `/tmp/tmp.x11pJL7014`. |
| `go test -coverprofile="$audit_build_dir/coverage.out" ./...` | pass | 11.05 s | Diagnostic coverage only; no percentage is treated as a gate. |

Coverage ranged from 69.8% (`internal/manifest`) to 100% (`internal/logging`)
among tested packages. `cmd/narratio` reported 0% because it has no tests. The
remaining package results ranged from 70.1% to 88.1%. Stage 12 owns the
risk-based interpretation; these numbers are inventory signals only.

### Code Graph Freshness And Structural Inventory

The `narratio` graph was rebuilt in `moderate` mode after the revision was
pinned. Its branch record reports the exact audited HEAD, `main`, and the
repository root above. The index contains 2,407 nodes and 13,181 edges across
224 modeled files: 1,494 functions, 136 methods, 226 structs, 12 interfaces,
and 20 modeled package nodes. The moderate filter excluded documentation,
examples, `.git`, `.codex`, and `cmd/narratio`; the executable entry point was
therefore verified through `go list` and direct inspection instead of graph
evidence. Internal production code is represented at the pinned revision.

Repository inventory at that revision:

- 23 Go packages, including `cmd/narratio`;
- 221 tracked Go files and 95 tracked `_test.go` files;
- 278 tracked files total;
- one process entry point, `cmd/narratio/main.go`, delegating to
  `internal/app.Execute`;
- 11 canonical stages returned by `internal/stage.All`; and
- 12 modeled interfaces, of which 11 are Narratio boundaries and one is the
  private AWS S3 client seam.

Graph call tracing from `internal/app.Execute` confirms command dispatch into
run, single-stage, clean, and session-helper paths, followed by configuration,
artifact/path, manifest, stage, storage, restore, and cleanup owners. The
production import inventory shows no lower-level package importing
`internal/app`; apparent graph rollups such as `stage -> app`, `adapters -> app`,
and `config -> app` came from test relationships or graph classification and
are rejected as production dependency reversals at this mapping stage.

### Metric Signals For Later Review

These are prioritization signals, not findings:

| Signal | Evidence | Assigned review |
| --- | --- | --- |
| High fan-in | `app.Error` (207), stage `Run` symbols (151), `app.Execute` (108), `stage.sessionPathsForEnv` (105), `manifest.New` (72), `manifest.MarkStageSucceeded` (56), `app.executeStages` (48), `artifacts.S3SessionPrefix` (41), and `artifacts.SessionWorkDirForCampaign` (37) | Owning behavior stages, then Stage 11 |
| High complexity | `app.executeStages` cyclomatic 54/cognitive 96; `previouscache.BuildPlan` 22/38; `analyzeStage.Run` 20/27; `audita.NewSubprocessRunner` 17/25; `app.SessionInit` 20/21 | Stages 2, 5, 7, 10, then 11 |
| Exact similarity | `app.Analyze`/`app.Publish`, `manifest.Load`/`LoadRun`, `manifest.Create`/`CreateRun`, adapter constructors, and Seriatim fake methods | Owning behavior stages, then Stage 11 |
| Test-heavy hotspot noise | Several test functions and fakes rank highly in transitive-depth and fan-in results | Stage 12; do not infer production risk from the metric |

### Automation And Fixture Inventory

- `.woodpecker/release.yml` is tag-only release automation. It cross-builds
  Linux, macOS, and Windows binaries with Go 1.25, then publishes release
  assets. It does not run tests, race tests, vet, or example validation.
- `examples/` contains 19 maintained files: pipeline, campaign, session,
  template, stable-input, and placeholder-audio fixtures. Configuration tests
  are documented as their validation owner.
- No fuzz tests, golden files, golden-update switches, opt-in/live test tags, or
  `go:generate` test mechanisms were found.
- Platform build constraints exist for the native no-replace directory tests
  and unsupported-platform fallback in `internal/fileops`.

## Execution Coverage Ledger

| Stage | Status | Evidence and result |
| --- | --- | --- |
| 0: baseline | complete | Revision/environment pinned; graph refreshed; inventories and every prescribed baseline command recorded. `TST-001` owns the non-blocking race limitation. |

| 5: restore and previous state | not_started | Assigned restore and previous-cache scenarios below. |
| 6: configuration and composition | not_started | Assigned configuration, CLI composition, and process-boundary areas below. |
| 7: adapters and shared support | not_started | Assigned external-boundary and cancellation areas below. |
| 8: ordinary stages | not_started | Assigned prepare/transcript behavior and disabled-outcome questions below. |
| 9: extraction | not_started | Assigned extraction promotion, provenance, and resume scenario below. |
| 10: analyze and dependencies | not_started | Assigned artifact dependency/source and selection scenario below. |
| 11: maintainability | not_started | Seeded by graph complexity, similarity, and fan-in signals only. |
| 12: test policy | not_started | Seeded by intended owners and baseline execution observations. |
| 13: synthesis | not_started | No final ranking or accepted-risk decisions yet. |

## Area Coverage And Ownership

Every area in the audit plan has a primary execution owner. `assigned` means it
has been mapped but not behaviorally audited.

| Inspection area | Canonical implementation owner | Primary audit stage | Status |
| --- | --- | --- | --- |
| Process and application boundary | `cmd/narratio`, `internal/app` | 6 (runner lifecycle portions in 2; publish/restore portions in 4-5) | assigned |
| Stage registry and runner | `internal/stage`, `internal/app` | 2 | assigned |
| Configuration | `internal/config` | 6 | assigned |
| Prepare and audio | `internal/stage`, `internal/audio`, `internal/previouscache` | 8 | assigned |
| Transcript stages | `internal/stage` plus tool adapters | 8 | assigned |
| Extraction | `internal/stage`, Notarius adapter, `internal/fileops` | 9 | assigned |

| Shared models and diagnostics | `internal/artifactmodel`, `internal/contracts`, `internal/logging` | 7 (maintainability revisited in 11) | assigned |
| Tests, examples, and automation | package test owners, `examples/`, `.woodpecker/` | 12 | assigned |

## Package And Interface Ownership Map

| Package | Owned contract or policy | Important boundaries | Audit owner |
| --- | --- | --- | --- |
| `cmd/narratio` | Process entry and exit; CLI delegates behavior to app | `main -> app.Execute` | 6 |
| `internal/app` | Command dispatch, composition, locking, planning, lifecycle, restore, cleanup, reporting | `Execute`, `executeStages`; consumes stage/artifact/manifest/adapter contracts | 2, 4-6 |
| `internal/config` | Strict discovery, defaults, resolve, template, and validation rules | Config models and load/resolve/validate functions | 6 |
| `internal/stage` | Canonical order and stage behavior | `Stage`, `ResumeValidator`, `Env`; adapter interfaces are injected | 2, 4, 8-10 |
| `internal/manifest` | Session/run models, transitions, validation, atomic persistence | `Store`; transition methods record but do not choose policy | 2 |
| `internal/artifacts` | Artifact identity/resolution, paths/keys, local store, remote current-state mechanics | `Store`; consumes explicit storage keys | 3, 5, 10 |
| `internal/artifactpolicy` | Configured source/destination identity and safety policy | Narrow validators used by config, artifacts, app, and stages | 3, 10 |
| `internal/artifactmodel` | Shared serialized artifact, contract, and provenance models | Data contract only | 3, 7 |
| `internal/pathsafe` | Confined relative path and destination mechanics | Narrow validation helpers; no stage policy | 3 |
| `internal/fileops` | Atomic files, copies, hashing, no-replace directory promotion | Filesystem mechanics receive explicit paths | 3, 9 |
| `internal/previouscache` | Deterministic previous-session requirement planning/materialization | Uses explicit object-store and artifact contracts | 5, 8, 10 |
| `internal/audio` | S3 audio spool/cache materialization | Uses `storage.ObjectStore`; no stage ordering | 5, 8 |
| `internal/contracts` | Bounds and shared JSON validation models | Data contract only | 7, 8 |
| `internal/logging` | Shared logger construction | `slog` composition | 7, 11 |
| `internal/adapters/whisperx` | WhisperX HTTP protocol | `Client` | 7 |
| `internal/adapters/seriatim` | Merge/normalize/trim/render subprocess protocol | `Runner` | 7 |
| `internal/adapters/audita` | Audita subprocess protocol | `Runner` | 7 |
| `internal/adapters/scriptorium` | Scriptorium run/render subprocess protocol | `Runner` | 7 |
| `internal/adapters/notarius` | Notarius invocation and receipt boundary | `Runner` | 7 (vertical behavior in 9) |
| `internal/adapters/notify` | Notification transport | `Sender` | 7 |
| `internal/adapters/storage` | Explicit bucket-relative object-store operations and S3 mechanics | `ObjectStore`; private `s3API` test seam | 7 |
| `internal/adapters/subprocess` | Shared bounded subprocess/config/log mechanics | Concrete helper package, not stage policy | 7 |

The graph reported no inbound production callers of `Stage.Declares`; text
search found definitions and test stubs but no production invocation. This
reduces the current impact of `ARC-001` but makes the interface's intended owner
and future use an explicit question rather than resolving the mismatch.

## Stage Contract Matrix

The table separates declared/static contracts from dynamic behavior. All
executed stages use the runner's session/run transitions. Unless noted, a
successful result records returned outputs, diagnostics, generated
configuration, and metadata; a different effective executed outcome can stale
succeeded downstream work, while force pre-stales succeeded downstream work.

| Order and stage | Inputs and outputs | Configuration and adapters | Skip/resume behavior | Materialization and manifest effects |
| --- | --- | --- | --- | --- |
| 1 `prepare` | Config, stable inputs, one audio mode, optional previous requirements -> canonical `inputs/**`, `audio/**`, optional `previous/**`, `manifest.inputs` | All resolved config; storage for S3/current previous state; audio/artifact/previous-cache services | No stage-specific resume validator or explicit self-skip | Writes canonical session inputs and deterministic input records; unlike processing stages, `Declares` labels produced canonical files as inputs. |
| 2 `transcribe` | Prepared FLAC files -> raw per-speaker JSON | WhisperX URL/language/retry/timeout/concurrency; `whisperx.Client` | Ordinary succeeded-record skip; no validator/self-skip | Bounded concurrent run-local writes, validation, then canonical transcript materialization. |
| 3 `merge` | Raw transcripts, speakers, autocorrect -> base transcript, optional report | Seriatim merge fields; `seriatim.Runner` | Ordinary succeeded-record skip | Normalized scratch inputs and run-local results validate before canonical transcript/report materialization. |
| 4 `polish` | Base transcript, glossary -> polished transcript, optional report | Audita fields/credential reference; `audita.Runner` | Ordinary succeeded-record skip | Run-local output, report, logs, and generated config; validates before canonical materialization. |
| 5 `normalize` | Polished transcript -> final transcript, optional report | Normalize plus Seriatim fields; `seriatim.Runner` | Ordinary succeeded-record skip | Manifest-first input; run-local validation then configurable canonical output/report. |
| 6 `trim` | Final transcript -> final-trimmed transcript and, when enabled, bounds | Trim, bounds, Scriptorium, and Seriatim fields; both runners when enabled | Disabled trim copies input and still succeeds; no explicit self-skip or resume validator | Run-local bounds/trim result validates then materializes; debug render is diagnostic, not output. |
| 7 `extract` | Final-trimmed source -> immutable index and configured lane outputs | Notarius executable/config/pipeline/timeout/output contracts; `notarius.Runner` | Disabled is explicit `notarius_disabled` self-skip; only current `ResumeValidator`; obsolete reruns, unsafe validation errors | Validates run-local receipt/bundle completely, promotes to unique immutable bundle, records checksums/contracts/provenance; identical repeated self-skip is stable. |
| 8 `render` | Final and final-trimmed JSON -> two Markdown transcripts | Render and Seriatim fields; `seriatim.Runner` | Disabled returns a zero-disposition result with skip metadata, therefore runner-level success rather than explicit self-skip; no validator | Run-local text validates non-empty before canonical materialization when enabled. |
| 9 `analyze` | Dynamic built-in, prepared, extraction, configured, and previous sources -> selected configured artifact outputs | Scriptorium artifact graph/selection; `scriptorium.Runner` | Missing config or no executable artifacts returns success with skip metadata; no validator | Topological run-local generation/reuse, validation, canonical outputs, deterministic metadata; static `Declares` omits dynamic outputs and several input families. |
| 10 `publish` | Session/run state, selected output rules, locks, previous cache -> remote run/output/current objects | Publish/storage/selection fields; `storage.ObjectStore` | Disabled publish or run upload returns success with skip metadata; force cannot bypass locks; no validator | Deterministic uploads; `current/manifest.json` before `current/run_id.txt`; commit metadata gates cleanup. Static prerequisites omit extract because disabled extraction is valid and lane resolution enforces required extraction state when selected. |
| 11 `notify` | No implemented persisted pipeline input/output | Optional `notify.Sender`; default no-op | Ordinary succeeded-record skip; no explicit self-skip or validator | Placeholder metadata and optional notification call; no returned output. `Declares` nevertheless advertises placeholder input/output paths. |

Configuration, adapters, skip policy, and dynamic outputs are not represented
by `IODecl`; their current canonical owners are the focused stage,
configuration, and integration contracts. Whether `IODecl` should remain a
partial display type or become an enforceable declaration is deferred as
`ARC-001`.

## Lifecycle Matrix

This is the intended contract map to be walked through both durable ledgers in
Stage 2. Cells marked `unknown` are not treated as implementation conclusions.

| Outcome | Session manifest intent | Invocation manifest intent | Downstream and next-invocation intent |
| --- | --- | --- | --- |
| First run | Pending/non-succeeded stage becomes running, then succeeded/failed/skipped; executing clears older result payload first | New run record; action `run`; terminal status records this invocation | Success enables later stages; failure stops current execution and an effective outcome change may stale succeeded downstream records. |
| Already-succeeded skip | Existing succeeded session record and payload remain unchanged, subject to resume validation | Action/status record a skip and stable reason for this invocation | Reusable result remains authoritative; pipeline continues. |
| Explicit self-skip | Session stage becomes skipped, clears older result payload, and may record bounded current skip details | Action was `run`, outcome is skipped with reason | Reconsidered later; a changed effective upstream outcome stales succeeded downstream work; identical extraction disabled skip is stable. |
| Failure | Current stage becomes failed with error; current output/log/config/metadata payload is cleared | Action `run`, failed outcome and overall failed run | Current execution stops; affected succeeded downstream work is intended to stale; later invocation reruns non-succeeded stages. |
| Interruption | Model admits `interrupted`, but no production transition reference has yet been found; process death can leave persisted `running` state | A process death can leave the run non-terminal; exact recovery semantics are unknown | CLI promises continuation of interrupted/partial sessions because non-succeeded stages run; explicit status normalization is `RSK-001` for Stage 2. |
| Forced replacement | Target execution starts fresh; succeeded downstream records are pre-marked stale; current target payload clears on running | Force flag and `run` action recorded | Replacement result determines later execution; locks and safety policy remain authoritative. |
| Non-resumable success | Prior success becomes stale while retaining details long enough for diagnosis/validation, then running clears them | Current invocation records execution after validation rejects skip | Obsolete result reruns; unsafe inability to decide stops without silently replacing current success. |
| Successful rerun | Target becomes succeeded with only new outputs/diagnostics/config/metadata | Current invocation records its own new success; earlier run manifests remain immutable | Changed effective outcome stales succeeded downstream work; identical effective outcome should avoid unnecessary invalidation. |

Stage 2 must separately verify save failures before and after each session/run
transition, first- and last-stage behavior, and which fields are retained in
historical invocation records.

## Cross-Boundary Scenario Assignments

| Scenario | Primary audit stage | Supporting packages and focused tests |
| --- | --- | --- |
| 1. Success becomes non-resumable, rerun fails, later reuse decision | 2 | `internal/app`, `internal/manifest`, `stage.ResumeValidator`; `runner_test.go`, `extract_lifecycle_test.go`, manifest transition tests |
| 2. Forced/changed upstream outcome with succeeded, self-skipped, disabled downstream | 2 | `internal/app`, `internal/stage`, `internal/manifest`; run-control, runner, extraction-lifecycle tests; disabled-stage detail revisited in 8 |
| 3. Extraction bundle followed by configuration/transitive-input change | 9 | Extract/resume, Notarius adapter, artifacts/fileops tests; downstream resolution revisited in 10 |
| 4. Published/restored/prepared previous state consumed locally by analyze | 5 | `internal/app`, `internal/previouscache`, `internal/audio`, `internal/artifacts`; restore/prepare tests; analyze consumption revisited in 10 |
| 5. Publish failure at every upload boundary, then status/restore/retry | 4 | Publish stage, storage fake/adapter, app status/restore; publish and operator-helper tests; restore interpretation revisited in 5 |
| 6. Restore identical/conflict/unsafe/cache/pre-manifest-install cases | 5 | Restore discovery/plan/execute/report, artifacts, previouscache, audio; restore test suite |
| 7. Cleanup after skipped/failed/locked/partial/committed publish | 4 | Publish metadata, post-publish cleanup, cleanup targets, pathsafe; publish/cleanup tests |
| 8. Cancellation through workers, HTTP, subprocess, storage, manifests | 7 | Adapter and subprocess tests; transcribe/stage tests in 8; runner reporting in 2 |
| 9. Disabled/unselected/reused/generated/extraction/previous source then publish filtering | 10 | Analyze, artifact catalog/resolver/policy, publish tests; config ownership in 6 and publish result in 4 |
| 10. Concurrent same-session invocation and lock cleanup failures | 3 | Runner lock lifetime in 2; local artifact store, path/file cleanup and lock tests in 3 |

## Preliminary Risk-To-Test Matrix

This matrix identifies intended owners only. It makes no sufficiency judgment.

| Architectural invariant or risk | Implementation owner | Intended test owner |
| --- | --- | --- |
| One deterministic canonical stage order | `internal/stage`, planner in `internal/app` | `internal/app/planner_test.go`, narrow registry tests |
| Session manifest is cross-invocation authority; run manifest is immutable invocation audit | `internal/app`, `internal/manifest` | Manifest transition tests plus assembled runner/run-stage tests |
| First run, skip, self-skip, failure, force, invalidation, and rerun transitions | `internal/app`, `internal/manifest` | App lifecycle tests as primary; manifest helpers own field mutation |
| Obsolete versus unsafe resume validation | Stage-specific `ResumeValidator`, runner | Extract resume tests plus runner integration tests |
| Run-local validation before canonical materialization | Individual stages and `run_local.go` | Focused stage package behavioral tests; fileops owns atomic mechanism |
| Strict config, defaults, identity, and cross-field validation | `internal/config` | Config package tests; example load/validation test samples assembly |
| Canonical path/key ownership and traversal confinement | Artifacts, artifactpolicy, pathsafe | Owning package tests; app/stage tests only for assembled policy |
| Immutable extraction promotion and provenance/checksum validation | Extract, fileops, artifacts, Notarius adapter | Fileops mechanism, extract behavior, artifact hydration, adapter contract tests |
| Deterministic artifact dependency and source resolution | Artifacts, artifactpolicy, analyze | Artifact/package tests and analyze package behavior tests |
| Previous-session consumption remains local in analyze | Previouscache/prepare/artifacts/analyze | Previouscache and prepare tests; one analyze boundary test for no remote call |
| Remote current pointer is publish's final commit point | Publish stage | Publish tests with stateful object-store fake; storage tests own transport only |
| Restore is confined, deterministic, conflict-safe, and installs manifest last | Restore app modules, artifacts/previouscache/audio | Restore plan/execution/workflow tests plus low-level path/file tests |
| Cleanup requires explicit scope and committed publish metadata | App cleanup modules, pathsafe | Cleanup-target and post-publish integration tests |
| Session single-writer lock and safe release | Local artifact store, app lifetime | Artifact local-store tests plus assembled concurrent runner tests |
| Adapter cancellation, error adaptation, and resource closure | Each adapter and shared subprocess package | Focused adapter boundary tests; stage tests sample propagation |
| Bounded deterministic transcription concurrency | Transcribe stage and WhisperX client | Stage concurrency/result-order tests; HTTP adapter retry/cancel tests |
| Secrets never persist or appear in diagnostics | Config/app composition and each adapter/logging boundary | Owning config/adapter tests plus selected assembled redaction checks |
| Default suite remains deterministic, offline, and credential-free | Every package; automation | Stage 12 repository-wide execution and test-policy audit |

## Candidate Register

No candidate is confirmed by Stage 1. Later owning stages must inspect the
implementation, focused tests, canonical contract, realistic scenario, and
callers before promoting or rejecting it.

### `ARC-001`: `IODecl` is not a complete or consistently classified stage contract

- Category: architectural boundary/ownership candidate.
- Evidence: `prepare.Declares` lists files it produces under `Inputs`;
  `analyze.Declares` omits dynamic input families and has no outputs;
  `publish.Declares` exposes only the manifest; and `notify.Declares` advertises
  placeholder paths although its result has no persisted output. No production
  caller of `Declares` was found.
- Contract tension: architecture says every stage declares required inputs,
  produced output state, configuration, adapters, lifecycle, and failure
  behavior; the Go interface declares only partial static artifacts.
- Realistic risk: a future planner, validator, or operator view could treat the
  interface as authoritative and make incorrect dependency or readiness
  decisions. Current likelihood appears low because the method has no
  production caller.
- Confirmation owners: Stages 8-10 for dynamic contracts, then Stage 11 for
  interface purpose/simplification. Smallest plausible outcome may be clearer
  naming/documentation, a complete contract, or removal; do not choose yet.

### `ARC-002`: disabled-stage “skip” terminology spans two different durable outcomes

- Category: architectural/lifecycle ownership candidate.
- Evidence: production use of `StageDispositionSkipped` was found only in
  extraction. Disabled render, absent/no-op analyze, and disabled publish return
  zero-disposition results with skip metadata, which the runner treats as
  success. Focused and operator docs use “skip” for several of these cases,
  while manifest docs reserve self-skip for a durable skipped state.
- Realistic risk: maintainers or operator features may assume all disabled
  outcomes clear state, are reconsidered, and invalidate downstream work in the
  same way. Conversely, changing them to explicit self-skip could break valid
  pipeline continuation or cleanup semantics.
- Confirmation owners: Stage 2 for runner truth table, Stage 4 for publish and
  cleanup, Stage 8 for ordinary disabled stages. Treat wording and behavior as
  unresolved until those flows are traced.

### `RSK-001`: interruption has a documented state but no mapped production transition

- Category: correctness/operational risk candidate.
- Evidence: `manifest.StatusInterrupted` is admitted and external docs promise
  continuation of interrupted sessions, but graph-augmented code search found
  the constant only in its declaration and an artifact rejection test. No
  production transition to it was found during mapping.
- Realistic risk: a killed process may leave session/run records as `running`,
  producing confusing status or dual-ledger interpretation even though the
  planner reruns all non-succeeded stages.
- Confirmation owner: Stage 2 must trace load normalization, process failure
  boundaries, status reporting, and next-invocation behavior before deciding
  whether this is a defect, compatibility state, or unused model value.

### `TST-001`: full race baseline fails in the concurrent transcribe test

- Category: test-suite execution candidate.
- Evidence: the race detector reported concurrent slice access in
  `internal/adapters/whisperx/fake.go:45` from transcribe workers in
  `TestTranscribeStageTranscribesPreparedAudio`.
- Observed impact: the canonical full race command exits nonzero, weakening its
  signal for other packages. The report currently points to a test fake, not a
  production data race.
- Confirmation owners: Stage 8 should inspect the worker/fake contract; Stage
  12 should classify suite impact and the smallest durable fix. Do not change
  the fake during this investigative stage.

## Candidate Classification Log

| Candidate signal | Classification | Reason |
| --- | --- | --- |
| Graph rollups `stage -> app`, `adapters -> app`, `config -> app` | rejected as a production reversal at Stage 1 | `go list` production imports contain no lower-level import of `internal/app`; graph connections include tests and ambiguous package grouping. Reopen only with a concrete production edge. |
| Similar wrapper/manifest/adapter functions | deferred metric signals, not findings | Similarity alone does not establish duplicated policy; owning behavior stages must first establish contracts. |
| Coverage percentages | deferred diagnostic signals, not findings | Stage 12 must reason from risk and test ownership, not a numeric target. |

## Unresolved Questions And Follow-Up

- Does loading a persisted `running` stage or run normalize it to
  `interrupted`, or is `interrupted` only a compatibility value?
- What exact session/run disagreement states are possible when either save
  fails at each transition boundary?
- Are disabled render/analyze/publish outcomes intentionally successful so
  pipeline continuation and optional outputs work, and do all operator views
  describe that distinction accurately?
- Is `IODecl` intended only for display/tests, or should it own enforceable
  dependency declarations?
- Does publish's omission of extract from its static prerequisite list combine
  safely with every configured extraction output rule and disabled extraction?
- Which native CI runner limitations explain the absence of validation jobs in
  the tag-only release workflow? Stage 12 owns the automation conclusion.

No accepted risks or final audit conclusions are recorded yet.

## Completed-Stage Evidence

### Stage 0

- Contracts and records: development guide, audit plan and sequence, all policy
  documents, repository/branch/toolchain state.
- Graph evidence: refreshed moderate index at exact HEAD; architecture,
  interface, complexity, similarity, fan-in, and `Execute` call trace queries.
- Commands: every baseline command listed above; Go/package/file/test and
  automation inventories.
- Candidates: `TST-001`; metric signals assigned to later owners.
- Explicit no-finding conclusion: no production dependency reversal into
  `internal/app` was found in the package import inventory.
- Limitation disposition: the graph excludes the executable entry point, which
  was verified directly; the race failure is owned by Stages 8 and 12 and does
  not prevent read-only audit work.

### Stage 1

- Contracts reviewed: architecture, testing and documentation policy; internal
  overview and every focused internal document; CLI, configuration,
  operations, and every integration contract.
- Code/evidence reviewed: canonical registry and stage declarations; all
  modeled interfaces; production import graph; application dispatch trace;
  explicit self-skip usages; interrupted-state usages; focused test ownership
  references.
- Outputs: package/interface ownership, area coverage, stage contract,
  lifecycle, cross-boundary scenario, and preliminary risk-to-test matrices.
- Candidates: `ARC-001`, `ARC-002`, `RSK-001`; no candidate was confirmed from
  mapping evidence alone.
- Explicit no-finding conclusion: the canonical stage order agrees across the
  registry, internal overview, CLI, and operations contract.
- Follow-up: all unresolved behavior has a named owner in Stages 2-12; every
  area and invariant has an implementation owner and intended test owner.
