buildLoopIndex additionally indexes each progression's collapsed form
(adjacent (degree,suffix) dedup + wrap), appended after raw entries so
every prior matcher winner is preserved except the enumerated
country-145 self-attribution. Repairs a pre-existing LIVE-detection
bug: a real 12-bar or 8-bar blues stream collapses to fewer names than
the raw KB degrees, so it matched NOTHING and the Jam Guide sat empty.
JamGuide reads authored plays through the collapsed station's
sourceIndex (all four guitar/piano/bass paths). Adds seedableLoop +
the round-trip roulette pool (smoke sweep: 4 failures / pool 52).
theory.js canonicalize exported. Critic PASS (fix-(a) additivity
proven registry-wide; pool reproduced from the spec; bass sourceIndex
station 5 -> raw 10 hand-checked).

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.
