# Phase 8 Plan 01: Bible Alignment Verification Summary

**5-dimension coherence verification (genre, vocal, theme, emotion, artist rules) with tiered OK/ATTENTION/ALERTE severity integrated into track production workflow**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-10T23:20:05Z
- **Completed:** 2026-04-10T23:21:35Z
- **Tasks:** 2
- **Files modified:** 1

## Accomplishments
- Added Verification de Coherence section with 5 structured checks (COH-01 genre, COH-02 vocal, COH-03 theme, COH-04 emotion, COH-05 artist-specific rules) to Step 03
- Implemented tiered severity system (OK/ATTENTION/ALERTE) replacing binary pass/fail for coherence verification
- Added coherence report table to production brief template so every saved track file contains its coherence results
- Extended post-verification interaction to combine linguistic and coherence alerts in a single user prompt

## Task Commits

Each task was committed atomically:

1. **Task 1: Add Verification de Coherence procedure to Step 03** - `8d2fd9f` (feat)
2. **Task 2: Add Verification de Coherence to production brief file template** - `27bf822` (feat)

**Plan metadata:** [pending] (docs: complete plan)

## Files Created/Modified
- `.claude/skills/create-track/steps/03-verify-and-save.md` - Added Verification de Coherence section (5 checks, severity rules, coherence table format, post-verification interaction) and coherence report to production brief template

## Decisions Made
- Combined linguistic and coherence post-verification interactions into one user prompt -- avoids two separate round-trips when both produce alerts
- Auto-generated style prompts (from Phase 7) receive "OK (auto-genere depuis la bible)" verdict for genre and vocal checks to avoid circular verification while still documenting the check
- Bible section references use exact field names from the example bible (Identite Musicale, Style Vocal, Palette Emotionnelle, Themes, Regles de Coherence) for consistency

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Verification de Coherence is in place; Step 03 now verifies Suno constraints + linguistic quality + bible alignment before saving
- Plan 08-02 (enhanced discography logging) can proceed -- it modifies a different section of Step 03 (Mise a Jour Discographie)
- Plan 08-03 (cross-track analysis) can proceed -- it adds Step 01 cross-track reading and Step 03 cross-track report

## Self-Check: PASSED
