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.

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
proven registry-wide; pool reproduced from the spec; bass sourceIndex
station 5 -> raw 10 hand-checked).

Smoke 886/886: RelatedProgressions ranking pinned (blues-12bar 152,
jazz-251-minor 156, no-collapse counterfactual 39 — replica grounded
against the live component; the 12-bar pin deliberately goes red when
D-62's collapsed indexing lands, message says re-pin). Validator:
registry-level progression-id uniqueness (the file walk missed
registry wiring dups — sabotage-proven with exactly one named error).
Whole-sprint App.jsx audio contract: zero hits since the seed.
Full-App SSR 60/60 across instrument x {normal, jam view}.

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).

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
(28/28 at the gate). Critic PASS (arithmetic recomputed from source
AND the built CSS; flex-basis override confirmed in dist).

Key chip + last-5 history + loop chips on one wrapping row; the
playhead loop chip and the enlarged current history chip are the
"now"; p-2 chrome trim. The text-6xl Now Playing column, its divider,
and the dead currentRN computation are gone — the loop shows once.

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" —
actually skip-then-step), fixed with the gate's own prescribed
wording, verified against its computed -3/-2 motion. 42/43 first-pass
checks; quality-context honesty verified against the styles' real
progressions.

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).

8 licks (31 total): bebop enclosure into the b3, Baker's 3-5-b7-b9
dim-flip over the V7, Powell ascent to the 9th, Garland-lane dominant
thirds fall; the b3->3 crush, pentatonic turnaround fall (verified
survives over a minor blues), Spann hammer dyads, the cry-and-melt
7#9 fill. All realized before prose was written. Critic PASS (35/35
prose claims recomputed in two keys; idioms verified to match their
names, not just cite them; dom7-heavy blues coverage accepted as
musically right).

SVG circle in the Knowledge Center Explore section: 12 majors outer
ring with key-signature glyphs, relative minors inner, live/locked key
solid accent with subdominant/dominant/relative soft-tiered; diatonic
chord chips inline (tap -> ChordDetailModal); wedge tap = local
preview only, app key state never touched; modal keys light the
correct ring and the hub teaches the parent-major relationship
("1# - G major's notes" for A dorian; 72/72 mode x root uniqueness
proven). Critic returned once (hub showed the wedge signature, not
the mode's), fixed, PASS on scoped re-gate.

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).

Piano licks live in <style>/piano.js licks arrays: required quality
(machine truth), deg XOR approach targeting the NEXT deg note
(enclosures fall out as idiom; same-type consecutive approaches
rejected), octave 0-2 with a 25-semitone cap proven one-semitone tight
against MiniPiano's 37-key window, 4-word piano technique vocab
(grace-note added; bend/vibrato impossible on keys), plus a dormant
smoke guard that activates when PianoLickCard.jsx exists. Smoke
879/879. Critic PASS (18 fresh sabotage cases, enclosure arithmetic
hand-verified, dormant guard proven to fire).

JamGuide resolveDegree imported directly (exported by the L-40
ride-along) via a .jsx resolve-retry hook; 17 new checks (export pin +
16 per-degree JamGuide sweeps) -> smoke 866/866. Sabotage-proven: a
perturbed JamGuide cell turns smoke red naming the exact drift.
Authored by the C-42 sweep agent pre-termination; verified and
sabotage-tested by Maestro (spend-limit fallback).

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
of all 912 placements exact; untouched instrument paths byte-identical;
import cycle proven safe in both load orders).

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
(non-dense proven byte-identical across 336 SSR combos). Critic PASS.

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).

Boogie walkups, 8th-note ramble, Jimmy Reed R-5-6-5 shuffle, 12/8
root-fifth-octave slow burn, minor box riff (quality-resolved 3rd
self-majorizes on bVI7/V7), walking turnaround + two-beat kicks. The
maj-7 climb authored as a typed chrom-below approach (pitch derived,
offset 11 never written). KB now 172 plays. Critic PASS first try
(all 76 patterns machine-realized in C AND A; 12 prose identities
recomputed, all hold key-agnostically).

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).

Smoke 836/836: a literal 16x14 degree truth table (all 224 cells
independently recomputed at the gate) pins the validator resolveDegree
behaviourally via span-probe recipes; technique vocab set-equality
between validate-kb LICK_TECHNIQUES and LickCard TECHNIQUE_VOCAB via a
scoped .jsx esbuild load hook. Both guards sabotage-proven twice

Guide-tone/tritone dyad system with the parallel half- and whole-step
laws, 7#9 as the codified blue note, the bVI7->V7 five-voice plane,
VI7b9 turnaround hinge, RH sixths; solo two-fisted vs rootless-band
contrasts per play. KB now 164 plays. Critic returned once (turnaround
jump-kicks bars 3-4 dyad orientations flipped + 2 prose rewordings),

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).

The station under the playhead auto-expands to the full voicing
gallery (VoicingBrowser dense) and advances with the music; other
stations keep their recommended thumb; level-filtered licks strip
below with token-boundary context sort and strip-owned "fits — now"
chrome; pin replaces tap-to-enlarge with identical onFocusChord
semantics; auto-follow never emits focus or audio; heard-live fallback
shows the live chord gallery. App.jsx and all renderers untouched.
