KB-sourced ranking per the one-screen spec: same canonical degree
shape +100 (with the mandatory collapse of consecutive equal
degree/quality pairs — a real detector-produced 12-bar fires its blues
relatives despite the raw-index matcher bug), same style +40, shared
transitions +12 capped 36, degree-set Jaccard, length penalty; floor
24, max 5, never padded; entries render name/style/level/annotation +
the chord chain realized in the live key as real buttons ->
ChordDetailModal. match.js: additive exports only. Ride-along: dead
currentChord prop dropped from the banner mount. Critic PASS (both
hand-verified scores recomputed independently; full entry lists
byte-matched on three scenarios; collapse counterfactual = 39).

Pop piano: 5 progressions x 2 plays (182 total) — triads/inversions
only, one sourced add9 shimmer; ballad rolls vs voice-led pillars,
doo-wop triplets vs one-finger walks, Pachelbel inversion stair,
tonic-drone pads, octave drive. Shapes: dim7/half_dim/aug/maj6/min6
each reach >=3 placeable grips, add9 gains a movable A-shape; dim
honestly left at 2. Audit also surfaced two WRONG pre-existing shapes
(half_dim E-Barre spells {0,3,6,7}; "Open Dadd9" is Dsus2) -> backlog.
Critic PASS (~110 independent checks; all additions pc-spelled in two
keys; strictly additive diff).

COMMIT_VOTES=2 (unchanged, ~one bar), REPLACE_VOTES=3 (a transient or
flapping detection can never displace a committed loop; section change
replaces one commit later), NULL_CLEAR=6 (post-L-30, nulls only start
~28 commits after the loop last played — traced exactly). Vote ref now
{committedKey, candidateKey, candidateCount}; agreement resets rivals.
Diff = one hunk in the progression useEffect; audio-contract grep
clean. Ride-along: theory.js docstring overclaim softened (L-30 gate
finding b), comment-only. Critic PASS (independent re-trace of all
five scenarios + 3 hostile traces; REPLACE_VOTES=3 proven load-bearing).

strIdx = rootStr-1 read OPEN [s6..s1] backwards: every rootStr-5 shape
sat 2 frets low, every rootStr-4 shape 5 frets low (A-shape C major
labeled fret 1 instead of 3) in ChordDetailModal/ExplorePanel/
CurrentJamPanel; rootStr-6 was accidentally correct (same pc both ends).
Now uses the shared 6-rootStr convention. Also: playChord docstring
octave example corrected. Critic PASS (6 independent fret checks +
252-entry pre/post sweep, structure unchanged).

Guitar row (placeable GUITAR_SHAPES via ChordDiagram) + piano row (4
pianoVoicing styles via MiniPiano), chips + explicit play button per
voicing through chordAudio; single shared stop handle; graceful
guitar-empty cell (only add9@E across 168 quality x root cells).
voicings.js gains an export-only GUITAR_SHAPES line. Critic returned
once (rootless voicings badged lowest voice as root — rootPc now passed
through), PASS on scoped re-gate.

A forced rootless sus2 collided the suspended-2nd and synthesized 9th onto one key
(notes [26,26,31]). Dedupe at the single funnel point ([...new Set(placed)]); pcs/bass
derived from the deduped array. No-op on default/chain path (L-11 render unaffected).
Critic: Set merges only identical absolute integers (same key) so no needed note is lost.

Completes the flagship Roadmap feature. App.jsx lifts a jamFocusChord state (additive,
+10/-0, audio callbacks/refs untouched); JamGuide emits the tapped station's {rootPc,
quality} via onFocusChord; Fretboard halos the 3rd/7th with a degree badge.
Also fixes root-cause guideTones: hasSeventh now keys on real m7/M7 (interval 10/11),
not length>=4 -- so add9/maj6/min6 no longer badge their 5th/6th as a '7'. Fretboard
badge derives its label from the actual interval (belt-and-suspenders). RoadmapTrack
lane self-corrects. Critic returned-then-PASS on re-gate; build + smoke + validator green.
