For a loop chord in the detected key, suggest up to 4 alternatives:
relative/diatonic-third sub, borrowed-minor iv colour, extension
colour, and the secondary dominant of the next chord — each with a
one-line teaching why, ranked softest to boldest. Worked through the
Am-C-F case under both the A-minor and C-major readings; circle-of-
fifths tie-in kept honest (relative + secondary-dominant are circle
moves, borrowed + extension are not). Mounts as a compact TryThis card
above RelatedProgressions in App's relatedSlot (file-disjoint). Critic
returned once (chordRootPC circular-import trap, sharp-spelled b6, one
wrong mediant claim — all copy/plumbing, rules verified correct),
fixed, re-gate waived (gate-prescribed fixes verified directly).

When a style is active (rolled or detected), RelatedProgressions leads
with same-style siblings reframed by data-derived character (minor
version / shorter form / extended form / reharmonized), computed from
mode/bars/qualities — no new KB content, no matcher change. Cross-style
same-changes entries demoted to a secondary section. Critic PASS (role
labels recomputed honest for blues + jazz; smoke-pin shift is
label-only). Deliberately avoids verse/chorus/bridge labels the KB has
no data for.

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).

Two-click flow (button -> style -> instant seed) writing lockedKey +
detectedProgression + a seeded committed-vote so the whole dashboard
fills as if detected and live playing continues from it; three
commit-layer guards specced (every unguarded seed dies exactly one
commit before earliest confirmation); fix (a): match.js additionally
indexes collapsed forms — repairing the pre-existing live bug where
10 progressions (incl. blues-12bar) never match detection, plus
country-145 misattribution; roll pool = steady-state all-offsets
round-trip passers (52/56); sourceIndex remap covers guitar, piano
AND bass play lookups. Returned twice, PASS on round-3 re-gate (a
literal implementation of the sweep protocol reproduced the pinned
numbers with zero interpretation gaps).

Zero-chrome always-open band replaces CurrentJamPanel below the
instrument row; ProgressionBanner survives as the single loop display
(RoadmapTrack retires, education folds into rail row headers); App
instrument state threads everywhere (JamGuide internal tabs die);
vertical rows, all stations expanded, playhead highlights; honest
wrap-based math (worst piano gallery 1,178px). Critic returned once
(Dm7-specific worst case + 3 factual fixes incl. the interim
page-yank), fixed, PASS on scoped re-gate (pixel-exact recompute).

Knowledge Center behaviour while a jam plays, zero clicks: the station
under the playhead auto-expands to the full D-30 voicing gallery and
advances with the music; level-filtered licks strip below with
context-first sort; pin gesture inherits onFocusChord semantics;
auto-follow never emits focus or auto-plays audio. Honest space math
(piano rail scrolls as normal state), 5-commit migration order for
L-33, four rejected alternatives. Critic returned once (piano gallery
width understated ~45%), fixed, PASS on scoped re-gate.

Muse explored three distinct philosophies for the live Jam Guide panel:
- Stage: live-play-at-a-glance (current chord huge, next preview, one big grip)
- Playbook: study/comparison grid (loop chords x voicings, more-ways expand)
- Roadmap: improv-first highway (playhead, guide tones, scale, voice-leading rails)
Each in docs/design/jam-guide-concept-{a,b,c}.md. Awaiting user pick (D-SEL).
