 | P-62 | KB voicings expansion: **pop piano cell** (next per kb-backlog) + audit `GUITAR_SHAPES` for qualities with <3 placeable shapes and author additions where idiomatic | content | done | — | `src/data/kb/pop/piano.js`, `src/data/kb/index.js`, `src/lib/voicings.js` (additive shapes only) | validator green; every new shape hand-verified (L-23 lesson: base-fret convention) |
 | D-61 | **Circle of fifths** in the Knowledge Center: interactive SVG (12 keys around the circle, live/locked key highlighted, relative minor ring, diatonic chords on tap-free hover/inline, key-signature glyphs), mounted inside ExploreSection; educational copy in the app's voice. **Returned once (2026-07-11):** modal hub key signature wrong (A dorian showed ♮ while its chips show F♯ — all 4 dropdown modal modes affected; fix = derive the parent-major signature, teaching "A dorian = G major's notes") + preview flat/sharp spelling split; geometry/rings/tiers/a11y all passed 60/60. Fixed + re-gate PASS (`c999c95` — hub computed from SCALES set-equality, 72/72 uniqueness, one spelling authority) | design | done | — | `src/components/CircleOfFifths.jsx` (new), `src/components/ExplorePanel.jsx` (ExploreSection integration only) | renders any key incl. none-detected; follows effectiveKey live; tokens + AA; zero clicks for the core view |
 | D-62 | **Jam Roulette UX spec** (doc): button up top ("Jam roulette", controls bar per one-screen's layout), genre picker (the 10 KB styles), randomization rules (random key; "interesting" progression selection — weight intermediate level + variety, avoid repeats within a session), how the seed fills the screen (seeds the committed loop + locked key so the banner/strip, voicing rail, licks, related progressions all populate exactly as if detected — reuse, don't duplicate), and the **detection handoff**: musicians start playing and live detection continues from the seed (spec the interplay with the L-31 commit layer: the seed behaves like a committed loop — replacement needs the same consistent evidence; New Song clears it) **Returned once (2026-07-11):** "matched by construction" false for 10/56 progressions — buildLoopIndex indexes RAW degrees while collapse changes name-sequence length (incl. blues-12bar: LIVE detection of a real 12-bar gets an empty JamGuide — pre-existing bug surfaced!); detector len-cap 8 makes collapsed 9-10 unconfirmable; round-trip empirical not constructional (blues-8bar loses to its own [V7,I7] alternation); funk-one-chord collapses to 2 names not 1; flag-1 timeline off by one (EVERY seed dies unguarded — guard even more necessary). Maestro direction: fix (a) — additively index collapsed forms in match.js (fixes live detection too); pool = empirical round-trip passers ∩ collapsed len 2-8. **Returned twice (2026-07-11):** round 2 verified fix-(a) construction/timeline/proofs sound but found the sweep protocol as written evicts all 8 two-name vamps (needs steady-state + all-offsets), behaviour-additive false in exactly one case (country-145 now self-attributes — an improvement, enumerate it), census 11 not 10, and the BASS plays path (BassGuideRows :530/:533) missed by the remap. Round-3 PASS (`see commit` — literal protocol implementation reproduced 4/56 failures + 52/56 pool + 11-census exactly; sourceIndex mechanism verified at current line numbers) | design | done | — | `docs/design/jam-roulette.md` | mechanism spec'd against the real App state (lockedKey, detectedProgression, progressionVoteRef); no state duplication; L-60 scope bounded |
-| L-60 | Implement Jam Roulette per D-62 (App.jsx UI-state + seeding fn; the roulette button + genre menu; 🚨 audio contract grep-gated — seeding touches display state and the progression refs ONLY, never callbacks). Ride-alongs: pass `dense` to the heard-live VoicingBrowser in the rail (D-51 gate flag — same fragile pair fit in the fallback path); one-screen.md §7 "two-octave cells alone" sentence is stale by a few px (D-51 gate nit) | engineering | claimed | D-62, C-50 | `src/App.jsx` (+ per D-62 — re-lock at promotion) | one click → genre → key+progression fills the jam dashboard; detection continues from it; New Song clears; build + smoke green; contract grep clean |
