What landed / 今次上咗乜

• Recorded narration wiring (#9b) — the 243 bundled voice/melody assets now play at runtime: per-language MP3 narration (EN / 粵語 / bilingual strictly serialized) through one non-overlapping queue with live-TTS fallback, melody cues per event, a persisted "use recorded narration" toggle, and a filesystem manifest-completeness contract test.
• Distinct SFX event mapping (Changelog history: M20 — Platform wave · 「平台穩陣」 (07-17 → 18) #10) — push/fetch/pull and every Build & Run phase get their own motif (four families), exhaustively tested as a pure mapping, with a per-cue audition grid in Settings → Sound.
• Repository-themed music (Changelog history: M21 — Advanced workflow completeness · 「補鑊工作流」 (07-19) #11) — deterministic synthesized theme per repo with override/clear; persistence moved to the Git-backed dedicated-setting store with one-time localStorage migration.
• Safe git auto-fix (Changelog history: M25 — Repository-bound API functions · 「API 變按鈕」 #15) — recognized failures (stale index.lock, gc/maintenance hang, non-fast-forward push, forbidden org push, detached HEAD) classified auto/confirm/manual with a one-click localized "Fix it" notification action; destructive fixes never run automatically.
• Native large-repo handling (Changelog history: M26 — Cheap LFS / Express Release · 「大檔平住存」 #16) — gc/maintenance suppression across status/add/checkout/fetch, fail-closed stale-lock removal, explicit "checking for changes" state, suspended polling for missing-on-disk repos, confirm-class nested-.git compression, and a genuinely wired idle repack (the review panel caught the toggle doing nothing — fixed pre-push).
• Stash inventory search — full shared filter + inline regex builder in the stash manager, registered in the search-surface audit registry.
• Regex builder responsive contract — small host dialogs no longer clip the builder (min-width floor, single-column collapse, internal scroll region), pinned by style-contract tests.
• Tab-strip fix — an unmeasurable (hidden/unrealized) strip no longer collapses tabs on zero widths; found by the first complete suite run and root-caused via bisect.

Verification / 驗收

• Every branch built by an isolated Opus agent and adversarially reviewed before merging (verdicts: 5× ship, 2× ship-with-fixes; all confirmed blockers fixed pre-push).
• Final gate: complete node script/test.mjs run, exit 0, zero failures, with the previously-skipped suites verified present in the log. npx tsc --noEmit clean at every merge.
• Filed #27: the test harness can silently skip batches between runs (how the tab regression hid), plus load-sensitive 5s waitFor budgets.

Remote checks (running, not yet verified):

• CI 30128771311 — running
• CodeQL 30128771300 — running
• Deploy Pages 30128771294 — running
• Cheap LFS cloud compression 30128771391 — ✅ success

All seven source branch tips proven ancestors of the pushed main, then removed with their worktrees; no stashes remain. Open work tracked in issues #23–#27. (Discussion pinning remains unavailable via the API here.)
