 > GATE 2026-06-15 (Critic) · **L-02 PASS** — build green; validator green (8 styles/40 progs/80 plays). 🚨 **Audio contract INTACT**: `git diff HEAD -- src/App.jsx` is +10 lines, zero deletions — only the `import JamGuide` line and the `<JamGuide …/>` mount (placed last, after the tuner block). `handleNote`/`handleChroma`/`handleOnset` lines do not appear anywhere in the diff; no `useCallback` dep, ref-sync `useEffect`, or `AudioCapture` prop was touched. Black-screen/infinite-restart risk avoided. All 5 props passed (`detectedProgression`, `effectiveKey`, `chordHistory`, `bpm`, `currentChord`) exist in App scope. Tabs derive from the KB registry (instrument availability from `style.instruments` keys, style labels from `meta.label`); matched-progression vs. dashed-fallback both render. Disabled instrument tabs marked "soon" with `disabled` + title.
 > GATE 2026-06-15 (Critic) · **D-01 PASS** — RoadmapTrack renders from props only (pure/presentational). Verified against the real KB: guide-tone honesty confirmed by running `guideTones` — C-major **triad** returns `hasSeventh:false`, secondary anchor = the 5th (pc 7), and the Station labels it **"5th"** not "7th" (`seventhKind` gate at line 113). The headline rail picks `voiceLeadingPairs(...)[0]` = the 7→3: Dm7→G7 ⇒ C→B (−1), G7→Cmaj7 ⇒ F→E (−1). BeatGrid station-start indexing is canonical-order-consistent with the stations array; playhead `pct` clamps at 0 when `position=-1`. Tokens used; `aria-current`, `role=progressbar` + `aria-valuetext`, focus rings present. Malformed/empty progression → graceful "no loop to map" card, no crash.
 > GATE 2026-06-15 (Critic) · **D-01b PASS** — ChordDiagram movable base-fret formula verified independently: **E-shape A7 → fret 5** ✓ (rootStr 6, rootPc 9: `((9−4)%12)=5`); A-shape C → fret 3 ✓; open-string root → octave barre (12), a sane degradation. Root-tone coloured in accent tier (`isRoot` → `#a855f7`), non-root dots light-gray (AA on dark board). Both `thumb`/`full` sizes; `full` adds finger numbers + label. Undefined/unplaceable shape (root > fret 15 or `!shape`) → graceful "—" placeholder, no crash — covers the empty-thumbnail path. Open vs movable forms both handled.
+> GATE 2026-06-15 (Critic) · **P-01 PASS** — validator green: `✓ KB valid — 9 style(s), 45 progressions, 90 plays` (gospel now included); `npm run build` green (gospel imported by `kb/index.js`, 87 modules, built in 5.65s). Schema: 5 progressions × 2 plays = 10 plays, all ids `gospel-`-prefixed, rn/qualities/bars all length-consistent with degrees, qualities all in CHORD_TYPES (min7/dom7/maj7/maj/add9/sus4/dim7). No duplicate id across all 45. Registered in `index.js` mirroring the other 8 styles (no broken import). **Voicings hand-verified** (independent pc computation matching the validator's): SHELL_6.maj7 → {0,11,4}=R-7-3 ✓; SUS4_5 → {0,5,7}=R-4-5 ✓; DIM7_5 → {0,6,9,3}=R-♭5-𝄫7-♭3 symmetric ✓; ADD9_6 → {0,2,4,7} full add9 (9th present) ✓; MIN9_5 → {0,2,3,7,10} full min9 ✓ — confirms the validator genuinely exercises these shapes via `checkGuitarShape`. **Theory** sound: backdoor ♭VII7=pc10 rises a whole step to I; #iv°7=pc6 passing chord; 6-2-5-1 + plagal IV-I Amen tag; cascading cycle-of-dominants all correctly spelled. **Authenticity** honest: attributions hedged appropriately ("traditional gospel turnaround", "reharmonized", "Every Praise … vamp feel", "e.g. Tenderly bars 5-7" as a back-door reference) — no claim that a specific recording uses an exact voicing; no music-theory error in any tip (Dorian-over-min7, Mixo-over-dom7, sus-non-resolution advice all correct). *Non-blocking nit*: a few shape comments list tones in interval order, not low-to-high string order (e.g. MAJ9_6 "R–3–7–9" sounds R-9-3-7) — labeling nicety, all tones present and correctly spelled; not a defect.
+> GATE 2026-06-15 (Critic) · **H-01 PASS** — every relative link resolves on disk: `GOAL.md`, `CLAUDE.md`, `src/data/kb/SCHEMA.md`, `src/data/kb/jazz/` (dir), `docs/agents/` + ROSTER/PROTOCOL/LEDGER all exist; `CONTRIBUTING.md` is correctly referenced as **"coming (tracked as task H-02)"** and does NOT exist on disk — honest, not a dead live-link. Every command real: `electron:dev`, `dev`, `electron:build:win|mac|linux` all in `package.json`; `scripts/validate-kb.mjs` exists. **No `frontend/` path remains**; build output dir stated as `release/` matches electron-builder `directories.output: "release"`. git clone URL `whattheflat/whattheflat.git` matches actual `origin`. **Honesty verified**: gospel described as "landing next" (not shipped, still in-review at review time); Piano/bass packs, Progression Builder, detection-powered drills all under **In progress**, not today; Roadmap Jam Guide listed as working-today (true — D-02 passed, MVP live). Leads with detect → guide → level up; links GOAL.md + docs/agents/. No overstatement found.
 > GATE 2026-06-15 (Critic) · **D-02 PASS** — the load-bearing integration is correct. **Independent rotation check**: `canonicalPos = ((position − rotation) % n + n) % n` translates a `findLoopPosition` index (which is into the *detected loop*) into the KB-canonical station RoadmapTrack/stationVoicings render. Worked a rotated [ii V I VI] of KB [I VI ii V] (rotation=2, n=4): playhead@detected-idx1(V)→canonical 3(V), @2(I)→0(I), @3(VI)→1(VI), @0(ii)→2(ii) — NOW lands on the chord actually playing. ✓ **rootPc parity** confirmed: thumbnail `rootPc` and RoadmapTrack station root are byte-identical `(((keyRoot+deg)%12)+12)%12`, and `keyInfo.root` (a note *name*, e.g. `detectKey`→"F#") is converted once via `chordRootPC` → pc, guarded `>=0`. stationVoicings `chords[i]` aligns 1:1 with `degrees[i]` (canonical). Auto-scroll is prop-driven off `position` (no rAF on the audio thread). Reflows (`flex-wrap`/`sm:flex-nowrap`), keyboard-reachable, AA contrast. NO_MATCH path → dashed fallback, never empty/crash. *Non-blocking deferral*: the DoD's "tap-station → **fretboard** guide tones" cross-link and `tailwind.config.js` edit were not delivered — the implementation cross-links via an inline enlarged ChordDiagram instead (flagged in-code as deferred). Panel is fully functional without it; recommend Maestro file the fretboard cross-link as a phase-2 follow-up.
