checkPianoRecipe stacks each hand low-to-high (nearest strictly above,
repeated pc -> octave up) and fails any hand spanning > 15 semitones
(minor 10th, SCHEMA rule 3); errors name style/prog/play/chord/hand/
span; refactored to a pure exported checker surfacing all errors per
recipe. Smoke +6 checks -> 799. Independent gate PASS (injection
surfaces 10 named errors exit 1; weakened gate caught behaviorally).

GuitarTab/PianoTab pass show=guitar/show=piano to VoicingBrowser
(D-23 prop); Knowledge Center + station-enlarge keep both rows by
design. Critic PASS (SSR: each tab renders only its row, legacy
content intact below).

Thumb window = whole octaves from the octave-C at-or-below the lowest
note (+ closing high C): shell thumbs 266px -> 142px, level with guitar
diagram thumbs. size=full and the legacy lh/rh path byte-identical.
Critic PASS (SVG geometry decoded back to absolute notes incl. the
octave-2 offset case; 793/793 smoke).

14 plays (7 progressions x 2): Bud Powell shells, rootless Type A/B,
guide-tone comps; comping rhythms; piano-angled improv. Hand spans
<= a 10th throughout. Critic returned once (6 prose voice-leading
overclaims on fifths-apart dominant alternation), fixed, PASS on
re-gate (all 6 corrected sentences arithmetic-verified both
directions); ride-along one-word polish per gate suggestion.
Rendering the authored pack in the Jam Guide is task L-24.

6 new level:'intermediate' progressions (tritone sub, rhythm-changes
bridge, gospel passing-dim walk-up, tonicized amen w/ borrowed iv,
Just-the-Two-of-Us loop, Sir Duke chromatic vi) x 2 guitar plays each;
all progressions in the three styles now carry explicit level. KB:
56 progressions / 112 plays. Critic returned once (3 caption theory
misstatements), fixed, PASS on re-gate (voice-leading arithmetic
hand-verified from shape constants).

ChordDetailModal Guitar/Piano tabs mount VoicingBrowser on top with
legacy grips/technique reference preserved below; Jam Guide enlarged
station view gains the browser on both instrument tabs; parse-null
never mounts a wrong-chord fallback. App.jsx untouched. Critic PASS
(SSR-verified both entry points; onFocusChord effects byte-untouched).

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.

Piano is computed (pianoVoicingChain over canonical stations), no
authored KB needed; guitar path value-identical; tap-station guide-tone
contract intact; App.jsx untouched. Critic PASS (303/303 empirical
station checks across 3 progressions x 3 keys; voice-leading threads).

Playable voicings per chord, lick/technique cards, intermediate
progressions with level tags, Knowledge Center IA revamp; L-11 hold
lifted and carried forward; /jam-loop 30m x 24 iterations scheduled.

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.

+705 checks (776 total): per quality x root x style, asserts pcs subset of voicingToneSet,
real 3rd present, true-7th when hasTrueSeventh, notes in [0,36], bass==min, no duplicate
absolute note, determinism, chain pcs-preservation. Surfaced the sus2 dup-note wart (fixed
by L-13). Critic adversarially confirmed the checks bite. Derived expectations, no hardcoding.

MiniPiano now dispatches: with a voicing={pianoVoicing(...)} prop it renders the
{notes,pcs,bass,style,label} on a 2-3 octave keyboard (root accent, bass amber-ringed,
thumb/full); without it, the legacy {rootPc,lh,rh} path is byte-unchanged so
ChordDetailModal + ExplorePanel render identically. Critic PASS.

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.

5 pop progressions x 2 plays: axis (I-V-vi-IV), '50s doo-wop, Canon pop line,
Mixolydian bVII, minor loop (i-bVI-bIII-bVII). Open campfire + movable/barre play each;
sus taught as fills (chords voiced plain). KB now 10 styles / 50 progressions / 100 plays.
Critic PASS (voicings hand-verified, no duplicate ids).

Leads with the dual vision + Roadmap Jam Guide; honest works-today vs in-progress split;
real quickstart; KB data-contract contributing hook; links GOAL.md + docs/agents/. Fixes
stale frontend/ paths and the release/ output dir. Critic PASS (all links + commands verified).

Renders movable {rootStr,offsets} and open {frets,onlyRoot} KB shapes; computes movable
base fret from chord rootPc in standard tuning (E-shape A7 -> fret 5); root in accent
purple; thumb/full sizes; graceful '-' fallback for unplaceable shapes. Critic PASS.

User chose concept C (Roadmap, improv-first highway). Re-planned L-01/L-02/D-01/D-02
and added L-01b (derived theory: guideTones, voiceLeadingPairs, soloScale) and D-01b
(secondary ChordDiagram thumbnail) to match Roadmap's needs.

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).

Adds a standing team that builds JamBuddy as both jam companion and
open-source learning platform, collaborating through files (shared
ledger + repo), conducted by one scheduled loop.
- .claude/agents/{maestro,professor,luthier,muse,critic,herald}.md
- dispatchable subagents, one per domain with file ownership + DoD
- .claude/skills/jam-loop/SKILL.md - the conductor (main loop appoints
workers, Critic gates, Maestro reconciles); generalises /kb-expand
- docs/agents/ROSTER.md - team, ownership map, cadence weights
- docs/agents/PROTOCOL.md - task-locking conflict guardrail, ledger
lifecycle, appointment algorithm, scheduling, PR-via-API
- docs/agents/LEDGER.md - live board seeded with sprint-jam-guide
- GOAL.md - links the ensemble; build still green

5 progressions (8-bar country I-IV-V, Wagon Wheel folk axis, ragtime
I-VI7-II7-V7 circle, Rising Sun 6/8 climb with corrected changes,
bluegrass I-IV-I-V) x 2 plays: open G/C-family boom-chick sets with
capo strategy, anchor-finger folk grips, barre fallbacks. Comping
documents boom-chick, Carter bass runs, Travis picking, train beat,
waltz. Sourced Lester Flatt G-run licks. Research corrections honoured
(Rising Sun is i-III-IV-VI, not Andalusian; ragtime is the full VI7
circle). Validator and build green.
