A compact TryThis card follows the playhead chord and shows ONE
suggestion at a time, cycling to the next valid substitution each time
the loop completes a pass (playhead wraps to a lower station). Over
Am-C-F the F cycles Dm -> Fm -> Fmaj7 -> E7 across passes, so the app
keeps offering a new idea and eventually teaches every honest move,
never a wrong one. Chip taps into ChordDetailModal; 0 subs -> no card,
1 sub -> static. Mounted App.jsx-only above RelatedProgressions in the
related slot; audio contract grep-clean; rotation logic exported pure
and StrictMode-safe. Critic PASS (2-pass rotation trace verified).

The 🎲 button opens a genre popover (Surprise me + the 10 KB styles);
rollJam seeds a random key + an interesting round-trip-safe
progression as a committed loop, so the whole dashboard fills exactly
as if detection found it — banner chips, voicing rail, licks, related
progressions. Three commit-layer guards keep the seed alive until the
band takes over: the null-clear skips seeded loops (a seed would
otherwise die one commit before the earliest possible confirmation),
the agreement branch confirms it, replacement swaps once real playing
is consistent, New Song clears it. An amber "rolled · style · name ·
bars — play it!" provenance chip flips to the normal loop marker on
first agreeing detection. Audio contract grep: zero hits. Critic PASS
(seed timeline hand-traced; §3.5 invariant verified at every write).

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).

The always-open zero-chrome band (GlanceRail + licks strip +
heard-live fallback) replaces CurrentJamPanel right below the
instrument view; the four-section dock becomes KnowledgeDock at the
bottom; RoadmapTrack unmounted (banner is the single loop display);
JamGuide's internal instrument/style tabs die — App's global
GUITAR/PIANO/BASS selector drives everything incl. the dock's
VoicingsSection; honest bass state (computed root-fifth-approach rows
+ notice, no galleries/licks); GlanceRail's scrollIntoView effect
deleted same-commit (would yank the document in page flow).
Ride-along: JamGuide resolveDegree exported (logic byte-identical) for
the C-40 drift guard. Critic PASS (SSR 22/22, audio-contract grep
zero hits, deletion sweep clean).

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).

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.
