 - **`pianoVoicing` should return `rootPc` (Luthier, tiny):** callers currently must attach it themselves (JamGuide and VoicingBrowser both do); returning it at the source removes the false-"R" foot-gun for future consumers (D-24 gate observation — NOT a live bug, both call sites verified correct 2026-07-08).
 - **`docs/kb-backlog.md` is stale (Professor, tiny):** still lists gospel/pop guitar + jazz/gospel piano as "todo" though shipped; P-30 (rnb piano) AND P-31 (blues piano, both 2026-07-10) need done entries — refresh next content iteration (flagged by P-30 + C-31 sweep, outside their locks).
 - **`scripts/loop-fixtures.mjs` header comment drift (tiny):** cites "App.jsx:322-324" for adjacent-dup suppression; L-31 shifted it to ~line 364 — comment-only, fix when the file is next touched (C-31 sweep finding).
+- **ProgressionBanner strip chips are div-onClick (Muse, small):** pre-existing a11y debt — history/loop chips should be real buttons (L-50 gate 2026-07-11; RelatedProgressions' chips already show the pattern to copy).
 - **Test-infra note (any agent writing throwaway SSR harnesses):** a bare `import('esbuild')` inside a `data:` module hook dies silently (ERR_MODULE_NOT_FOUND in the hooks thread, exit 1, zero output) — smoke.mjs:1047's interpolated `import.meta.resolve` pattern is load-bearing; prefer esbuild pre-bundle harnesses (confirmed empirically twice, 2026-07-11).
 - **GUITAR_SHAPES self-audit in smoke (Critic, small — P-62 gate suggestion 2026-07-11):** pc-spell every GUITAR_SHAPES entry against its quality in smoke — the validator audits only KB chord steps, never the shape library itself; would have caught both wrong shapes below and guards future additions.
 - **Pop piano prose uses absolute note names (Professor, tiny — P-62 gate flag):** ~8 spots (pop/piano.js:88,117,130-133,159,186) say e.g. "the G holds; top C→B" — correct only in the declared reference key; degree-ify before any piano-prose render surface lands (sibling of the bass-tips-surface backlog item).
