 | D-72 | Same-style related-progressions design (user answer = reuse existing KB): decide the presentation — when a style is active, RelatedProgressions leads with same-style siblings reframed as "variations / sections to try in {style}" (labels/section framing that reads as bridge/chorus/variation without new content); how the active style is known (roulette seed carries it; live detection's match yields it — name the prop/source); whether cross-style entries stay as a secondary "other styles with these changes" section or are dropped when a style is locked; empty/edge states. Files disjoint from the rail/licks chain (RelatedProgressions.jsx only) → runs in PARALLEL | design | done | — | `docs/design/related-same-style.md` | presentation spec'd against the real RelatedProgressions/match.js; active-style source named; L-72 bounded |
 | L-72 | Implement D-72: RelatedProgressions leads with same-style variations when a style is active; reframed labels; cross-style demoted/dropped per the doc. **Unblocked 2026-07-13** (no song forms). Resolutions: (finding-A) when a style IS locked, DROP the secondary cross-style section — same-style only, per goal #6 + the user's "not necessarily other styles"; keep cross-style ONLY when no style is locked (match.matched===false). (finding-B) null the role phrase when a same-style sibling shares NO transitions with the loop (no false "variation" claim — just name + level). Re-pin smoke §8 labels ('shares I7→V7'→'shorter form' etc.; scores stable) | engineering | claimed | D-72 | `src/components/RelatedProgressions.jsx`, `scripts/smoke.mjs` (§8 re-pin) | same-style-only when locked; honest cross-style only when unlocked; role phrase honest (finding-B); build + smoke green — **PASS** (`see commit` — findings A/B verified; gate added 2 durable smoke assertions, 893/893) |
 | D-73 | **"Try this" chord-substitution feature** design (engine rules + UI): for a loop chord `{rootPc,quality}` in the detected key/style, a SMALL curated set (~3-4) of alternative chords — recommend the categories (relative/diatonic-third sub, borrowed-minor colour e.g. IV→iv, extension/colour e.g. maj7/add9/sus, a circle-of-fifths / secondary-dominant move) — each with a plain one-line WHY that teaches. Concrete worked examples for the user's Am–C–F case (both A-minor and C-major readings), arithmetically correct (the gate WILL recompute). The UI surface: where it mounts in the jam dashboard (per-station in the rail? a "Try this" line under the loop? — decide, keep it glanceable, tappable→ChordDetailModal), honest circle-of-fifths tie-in (a lens for the relative/neighbour subs, NOT claimed for borrowed/extension), edge states (no key / atonal), keep-it-simple (learnable, not a reharm engine). Use a SEPARATE component (disjoint from RelatedProgressions.jsx).
