Ver1 Step 3 Results: Functional Completion by Requirement Domain

Summary

Step 3 implementation has been completed for the planned functional-completion scope in a practical personal-scale form.

Implemented in this step:

1. Revision history and acceptance workflows for transcripts.
2. Search over accepted transcript revisions.
3. Export of accepted transcript data.
4. API routes for jobs, revisions, search, and export.
5. UI pathways for revision management, search, and export.
6. Carry-forward integration updates for Step 1/2 follow-ups owned by Step 3.

Implemented Changes

1) Data model expansion (functional domain)

Updated src/transcription/models.py:

• Added JobStatus.COMPLETED.
• Added TranscriptRevision table/model:
  • job_id
  • revision_number
  • text
  • source
  • accepted
  • created_at
• Added Job.revisions relationship.

This supports immutable revision history and accepted-transcript semantics for search/export.

2) Step 3 service layer

Created src/transcription/services/library.py with service-backed functional operations:

• list_jobs(...)
• get_job_detail(...)
• add_revision(...)
• accept_revision(...)
• list_revisions(...)
• search_accepted_transcripts(...)
• export_transcripts(...)

Key behavior:

• revisions are append-only and incrementing
• accepted revision is unique per job
• accepting a revision syncs canonical transcript and sets job to completed
• search scope is accepted revisions only
• export emits deterministic record payloads for archive workflows

3) Worker integration for revision provenance

Updated src/transcription/worker.py:

• Success path now calls add_revision(..., source="worker", accepted=False).
• Worker still persists canonical transcript and transcribed job state.
• Initial machine transcription now appears in revision history.

4) API functional completion

Created src/transcription/api/routes.py and wired in src/transcription/app.py.

New endpoints:

• GET /api/jobs
• GET /api/jobs/{job_id}
• GET /api/jobs/{job_id}/revisions
• POST /api/jobs/{job_id}/revisions
• POST /api/revisions/{revision_id}/accept
• GET /api/search?query=...
• GET /api/export?accepted_only=true|false

5) UI functional completion

Updated src/transcription/ui/jobs_page.py:

• Job detail now includes revision history panel.
• Added user revision submission.
• Added revision accept action.
• Added /search page for accepted transcript search.
• Added /export page for accepted transcript export preview.

Test Evidence

Added/Updated Tests

1. tests/services/test_library.py

   • revision append/accept behavior
   • accepted-only search behavior
   • export payload behavior

2. tests/api/test_routes.py

   • jobs/revisions/search/export API serialization and contract behavior

3. tests/test_models.py

   • completed status transition coverage
   • TranscriptRevision persistence and relationship coverage

4. tests/services/test_worker.py

   • success-path now verifies initial worker-generated revision persistence

Full Validation Run

Executed and passing:

• uv run pytest -q

Requirement Slice Coverage (Step 3)

Slice	REQ Coverage	Status	Evidence
Core lifecycle completion and visibility	REQ-0, REQ-2, REQ-3, REQ-5, REQ-6	met	worker integration + API/UI jobs routes + tests
Revision history and acceptance	REQ-3, REQ-4, REQ-5, REQ-11	met	TranscriptRevision, services/library.py, UI revision panel, tests
Search over accepted transcripts	REQ-5, REQ-11	met	search_accepted_transcripts, /api/search, /ui/search, tests
Export transcript data	REQ-4, REQ-5, REQ-11	met	export_transcripts, /api/export, /ui/export, tests
Prompt and verbatim flow continuity	REQ-12	met (continued)	worker transcription flow unchanged in prompt-loading contract

---

Carry-Forward Integration Updates

Updated:

• docs/ver1/ver1-step1-2-carry-forward-checklist.md

Step 3 updates recorded for:

• CF-A1: in progress with Step 3 inspection evidence
• CF-A3: in progress with boundary-discipline evidence
• CF-C1: done (Step 3 traceability artifacts integrated)
• CF-C2: in progress (routing preserved for later steps)

---

Residual Follow-ups

1. Step 4: migration rehearsal and rollback runbook execution for schema changes.
2. Step 6/7: broader error-path inventory closure and logging field normalization.
3. Step 9: release readiness reconfirmation for runtime ownership and migration behavior.

---

Step 3 Exit Assessment

• Requirement-domain functional completion: met
• Data integrity and state consistency for new flows: met
• API/UI parity for new Step 3 features: met
• Test and regression safety: met
• Carry-forward integration obligations (Step 3-owned): met/in progress as routed

Step 3 is complete and ready to hand off to Step 4.
