# Phase 5: French Linguistic Engine Verification Report

**Phase Goal:** The system can verify French lyrics for syllable accuracy and rhyme quality using language-specific rules, and provide pronunciation guidance for Suno rendering.
**Verified:** 2026-04-10T21:26:58Z
**Status:** gaps_found
**Re-verification:** No -- initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | System counts syllables per line applying e muet, dierese, synerese, and hiatus rules -- showing work step by step | VERIFIED | syllables.md 450 lines: 6-step procedure with ATTENTION warning against estimation, 113-entry dierese/synerese table, 5 known-answer validation tests, genre-dependent counting (pop vs rap) |
| 2 | System scores French rhymes using formal IPA classification: pauvre/suffisante/riche/richissime based on phonetic analysis | VERIFIED | rhymes.md 348 lines: 6-step IPA-first procedure with anti-orthographic safeguard, 34 pre-classified rhyme pairs, 33-entry orthographic trap table, 5-step suggestion workflow for weak rhymes |
| 3 | System provides pronunciation guidance flagging high-risk French words for Suno and mandates All lyrics in French in style prompt | VERIFIED | pronunciation.md 387 lines: 6-scan procedure with ALERTE/ATTENTION/INFO severity levels, 44-word watchlist with safe alternatives, 38-entry liaison table, 4 rewrite strategy categories |
| 4 | Reference files are wired into the active track production workflow | PARTIAL | CLAUDE.md mandates consultation of reference/linguistic/french/ (lines 70, 79). But steps/03-verify-and-save.md (lines 42 and 94) contains an active deferral telling Claude not to perform linguistic verification until a future phase |

**Score:** 3/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| reference/linguistic/french/syllables.md | 6-step syllable procedure, 80+ dierese/synerese table, 5 validation tests | VERIFIED | 450 lines, status: complete, 113 table entries organized by suffix group, 5 tests with known answers |
| reference/linguistic/french/rhymes.md | IPA-first 6-step procedure, orthographic traps, pre-classified table, suggestion workflow | VERIFIED | 348 lines, status: complete, 34 rhyme pairs pre-classified, 33 trap entries in two tables |
| reference/linguistic/french/pronunciation.md | 6-scan procedure with severity levels, liaison table, 40+ watchlist, rewrite strategies | VERIFIED | 387 lines, status: complete, 44 watchlist words in 4 categories, 38 liaison entries (obligatory/forbidden/optional) |
| .claude/skills/create-track/steps/03-verify-and-save.md | Active linguistic verification integrated into track production | PARTIAL | File exists and handles Suno technical checks (char limits, tag count, language tag). Linguistic checks (syllables, rhymes) are explicitly deferred at lines 42 and 94 |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| syllables.md | pronunciation.md | Cross-reference IPA notation | WIRED | Line 450: explicit link to pronunciation.md |
| rhymes.md | pronunciation.md | Cross-reference IPA and nasal vowels | WIRED | Lines 27 and 348: explicit links |
| rhymes.md | syllables.md | Cross-reference syllable counting | WIRED | Line 348: explicit link |
| pronunciation.md | syllables.md | Syllabic density scan reference | WIRED | Line 51: Consulter syllables.md pour le comptage |
| pronunciation.md | reference/suno/format.md | All lyrics in French constraint | WIRED | Line 387: explicit cross-reference |
| CLAUDE.md | reference/linguistic/french/ | Verification mandate (all French tracks) | WIRED | Line 70: Consulter reference/linguistic/french/ pour les tracks en francais; Line 79: Ne jamais sauter la verification linguistique |
| steps/03-verify-and-save.md | syllables.md / rhymes.md / pronunciation.md | Active invocation in workflow | NOT WIRED | SKILL.md References section omits linguistic files; step 03 defers linguistic verification to a future phase at lines 42 and 94 |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| .claude/skills/create-track/steps/03-verify-and-save.md | 42 | Deferral note in step procedure instructions | Blocker | Tells Claude not to perform linguistic verification (syllables, rhymes) during track production |
| .claude/skills/create-track/steps/03-verify-and-save.md | 94 | Same deferral note in output template | Blocker | Will be written verbatim into every produced track file Rapport de Verification, persisting the deferral in saved artifacts |

### Human Verification Required

#### 1. Active Verification Behavior Under Instruction Conflict

**Test:** Run the create-track skill for a French-language track. Observe what appears in the Rapport de Verification section of the produced file.
**Expected:** The report includes syllable count per line, rhyme quality classification per section thresholds (chorus=riche 3+, verse=suffisante 2+), and the pronunciation scan output -- without any deferral note.
**Why human:** The step 03 file tells Claude to defer, while CLAUDE.md tells Claude to always verify. Which instruction wins depends on Claude runtime behavior during the skill execution. Static analysis cannot resolve this conflict.

### Gaps Summary

Phase 5 built all three reference files to and beyond specification:

- `reference/linguistic/french/syllables.md` (450 lines, 113-entry table, 5 validation tests) -- exceeds the 80-entry minimum from the plan
- `reference/linguistic/french/rhymes.md` (348 lines, 34 pre-classified pairs, 33 orthographic traps, suggestion workflow) -- fully complete
- `reference/linguistic/french/pronunciation.md` (387 lines, 44-word watchlist, 38 liaison entries, 4 rewrite categories) -- exceeds the 40-word minimum

The files are substantively correct, internally cross-referenced, and CLAUDE.md mandates their use.

The blocking gap is in `.claude/skills/create-track/steps/03-verify-and-save.md`. The deferral note at lines 42 and 94 was appropriate before Phase 5. It was not removed when Phase 5 completed. As a result, the active workflow step tells Claude that linguistic verification is a future feature -- directly contradicting what Phase 5 just built.

The fix is narrow: remove the two deferral notes and add a linguistic verification section to step 03's Rapport de Verification that invokes the Phase 5 reference files. The SKILL.md References section should also be updated to list the linguistic files.

The Phase 5 PLAN correctly scoped deep Phase 7 integration as future work. However, removing the deferral placeholder is not Phase 7 work -- it is the final connection step that makes Phase 5's reference files active in the system.
