The rotating Try-this card was gated on a live-detected currentChord,
so a rolled Jam Roulette (which locks a key + loop but leaves the
history empty until you play) showed nothing. TryThis now falls back
to the first loop chord that yields a substitution, so the card is
visible whenever a loop is on screen in a locked key; the live-playing
path is unchanged and honest-empty (no key / no loop) is preserved.
Critic PASS (combined gate: renders for the rolled-jam case, no
infinite render).

The dashboard licks strip now follows the global GUITAR/PIANO/BASS
selector: guitar shows LickCard tabs, piano shows the PianoLickCard
piano-roll (jazz/blues/gospel/rnb), bass shows an honest empty line.
Every strip card is a uniform compact 220x150 box (tab/roll normalized
to a 104px-tall panel) so the licks stop hogging space. Play buttons
removed from the strip. Knowledge Center LicksSection + LickCard left
byte-identical. .dark-scroll applied to the rail/strip scrollers.
Critic PASS (combined gate).

Dashboard voicings rail: guitar galleries capped to 4 shapes
(recommended-first, then open, then movable by base fret; prop-gated so
the Knowledge Center and chord modal keep all shapes); piano voicings
render as a 2x2 grid of size="mini" (scale 0.60) keyboards under the
rail's dense path only. Play buttons removed globally from
VoicingBrowser per the user ("leave them off, better not") — the
Knowledge Center + modal render byte-identical minus the buttons.
A scoped .dark-scroll utility (thin, #2a2a2a on transparent) dresses
the dashboard scrollers. Critic PASS (combined gate: byte-identity
proven, zero play buttons everywhere, contract intact).

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).

Additive suggestSubstitutions({rootPc,quality}, keyInfo, opts) returns
up to 4 honest, correctly-spelled chord alternatives in the detected
key: relative/diatonic-third, borrowed-minor iv (flat-spelled b6),
diatonic extension colour, and the secondary dominant of the next
chord — each with a plain teaching why. A sabotage-proven smoke
truth-table pins the tables (Am-C-F both readings, the Rule-D blues
moves). Critic returned once (Rule C self-suggested the sounding chord
on 7th inputs: Dm7->Dm7, plus a latent add9-on-minor mis-spelling),
fixed (skip self-quality extension; omit category C when nothing new
to add), PASS on scoped re-gate. Smoke 903/903; theory.js purely
additive.

When the loop matches a KB style (rolled or live-detected),
RelatedProgressions leads with that style's other progressions under a
"Try these in {style}" header, labelled by data-derived character
(minor version / shorter form / extended form / reharmonized) computed
from mode/bars/qualities — no cross-style jumping. The role phrase is
suppressed unless the sibling is genuinely related (same changes or a
shared transition), so no false "variation" claim. When no style is
locked, today's cross-style list is preserved byte-for-byte. Smoke
893/893: §8 re-pinned (scores stable 92/156, labels moved) plus two
gate-added durable assertions (finding-B suppression + no-match
fallback). Critic PASS.

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).

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

Chrome shave (rail p-2, rows p-1.5, dense cells p-1.5) so the
284+160 piano pair fits with real margin even under a classic Windows
scrollbar (was a genuine break: 452 > 439 at old paddings); gallery
basis 300->320 so a piano recommended cell can never share line one
(prominence for free) while guitar keeps 4 cells per line;
recommended-cell border strengthened to full accent. Playhead
highlight-only contract proven intact; non-dense mounts byte-identical

Key chip + last-5 history + loop chips on one wrapping row; the

8 licks (39 total): the gospel-scale run with the b3->3 crush, shout
run-up, harmonized sixths walk (the m6 falling exactly where the major
scale demands), diminished roll over the passing #iv dim7; the nine
sigh, quartal slip (grace-brushed fourths, all Dorian), the Dilla
lazy chromatic drop (derived approaches), pentatonic turn onto the 9.
Critic returned once (one interval claim said "each move a step" —

survives over a minor blues), Spann hammer dyads, the cry-and-melt

Pop piano: 5 progressions x 2 plays (182 total) — triads/inversions

Realizes SCHEMA bass patterns per station (root at lowest playable
position, degs via the shared resolveDegree, typed approaches derived
from the next station with the open-E octave-displacement rule), lays
them out as compact E-A-D-G tab cards (lick-tab visual idiom), all
plays side by side, each with sequential playback through chordAudio
(negative notes documented-legal; one sequence at a time). Computed
root-fifth-approach line remains the fallback for pack-less styles.
BASS is now real end-to-end. Critic PASS (independent re-realization

Every loop chord is a permanently expanded vertical row: education
header (solo-scale label, guide-tone aim dots with honest 5th
fallback, voice-leading chip incl. the wrap-around loop rail) + the
full voicing gallery for the global instrument; galleries flex-wrap,
zero row-level horizontal scroll; playhead adds highlight classes only
(rows proven byte-equal modulo highlight artifacts); pin simplified to
a focus toggle (onFocusChord contract byte-compatible with L-40).
VoicingBrowser: show='bass' now renders an honest one-liner instead of
falling through to both galleries; dense drops section chrome

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

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

deleted same-commit (would yank the document in page flow).

COMMIT_VOTES=2 (unchanged, ~one bar), REPLACE_VOTES=3 (a transient or

{committedKey, candidateKey, candidateCount}; agreement resets rivals.
Diff = one hunk in the progression useEffect; audio-contract grep

Completes the flagship Roadmap feature. App.jsx lifts a jamFocusChord state (additive,

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.
