Product outcome

After analysis, the workspace names tonight's first lyric cue so the singer can orient immediately instead of staring at a generic ready card. The first lyric cue is the earliest valid section that still has a lyric, then the highest-priority valid lyric role in that section. Count and transition cues stay out of this action.

Exact current identity

  • Protected base: develop@acdbea6344fe1231c39535b575f4de35e4c607c9.
  • Exact head: a92bd8f4fe57127641c749f9572931ee5f85c628.
  • Branch: feat/workspace-hear-first-lyric-cue.
  • Open, non-Draft, mergeable, unmerged.

Current behavior

  • FirstLyricCueCallout renders bilingual part, lyric, section, and start-time copy.
  • Workspace is honest map navigation: Open ... arms only after renderer-owned section navigation succeeds and never claims playback.
  • Workspace scrolling honors prefers-reduced-motion; default uses smooth scroll and reduced-motion uses auto.
  • Player exposes Hear ... only when its owning player supplies the playback callback and delegates the exact cue start second.
  • Cue identity changes reset armed state, including A → B → A returns.
  • Runtime cue selection rejects malformed roots/collections, non-finite or negative section starts, unknown rehearsal priorities, non-string lyrics, and blank/non-string role ids before sorting/selection.
  • Analysis section.id remains domain data rather than DOM-ID authority.

Test-first repair lineage

  1. RED 7d9d7a3cc57f7bc737d7a46821816d4bcfa8eb40 requires callback-only Player Hear behavior; 5228616cd482ddc0bffe928985d62a40ba95a8e1 / 063b6294fc83c43590e91afacea11cd3c4144fbf implement it.
  2. RED 156768c1245a14ed98746a3aa7ee39cb97bd801e covers A → B → A; GREEN 744e554dd6cf59532d86695ce15609ce5490b36a resets state by cue identity.
  3. RED 41d9748dbf11b1c5e1bebd5b95f49c567cea72dc plus follow-up branch coverage rejects unsafe cue metadata; bd135db8d0277eeddb48141c8ef1d4f70554e987 / 778a2ed285b6d6dfc5f03f0e0698e553a5e90fb7 implement those boundaries.
  4. RED bc588cdc67b3c7e2ed2871cac13a65fbc386b851 requires honest Workspace map navigation; renderer-position hardening removes analysis-controlled DOM ids.
  5. RED bea2bd2e872b54cfe4361062df29e93c394cbaa7 requires reduced-motion auto scrolling; GREEN 5d0e5b2f37d78e2a3c4185859a418877ebf8a9ed adds the narrow preference-aware helper and doctoring records the non-certification boundary.
  6. Current head a92bd8f4fe57127641c749f9572931ee5f85c628 adds the latest runtime identity boundary by rejecting malformed lyric-role ids before a role can become cue authority.

Exact-current-head repository evidence

All nine currently emitted repository workflows for a92bd8f4fe57127641c749f9572931ee5f85c628 are terminal. ci, release, build-baseline, sbom, SAST Semgrep, Bandit, and secret-scan-gate are successful. security-audit and aggregate Security Scan fail only on the inherited protected-base JavaScript HIGH dependency set owned by canonical #783; this branch has no dependency/root-lock or suppression delta.

The two CodeRabbit threads are resolved/outdated. There is no qualifying independent non-author exact-current-head approval. Predecessor or dismissed review evidence is not transferred.

Dependency routing

Security and accessibility notes

Untrusted rehearsal song, section/role metadata, cue text, and analysis-owned identifiers remain data only. Mitigations include finite non-negative section starts, allowlisted priorities, string lyric and non-empty role-id evidence, callback-only Player authority, one-pass copy interpolation, renderer-position navigation, no analysis-controlled DOM ids, and reduced-motion presentation handling. No new filesystem, network, subprocess, IPC, WebView, model, export, or persistence authority is added.

Merge gate

Merge only after one unchanged exact head simultaneously has every applicable repository and central required gate terminal-success, exact required coverage/docstring evidence, zero valid unresolved findings, canonical dependency prerequisites integrated/revalidated, a qualifying independent non-author last-push approval, and ordinary protected-branch acceptance. Queued/pending/skipped/cancelled/failed/stale/predecessor/protected-base/model-only/self/author evidence is non-passing.

📝 Walkthrough

Walkthrough

첫 가사 큐의 입력 검증과 선택 규칙을 강화했습니다. Workspace는 reduced-motion 설정을 반영해 섹션으로 이동합니다. player는 재생 콜백이 있을 때만 Hear 동작을 표시하고 시작 시간으로 위임합니다. 관련 번역, 계약, 문서, 테스트를 갱신했습니다.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 84017

The feature adds first-lyric cue navigation and playback, but malformed nested cue metadata may still crash workspace rendering for affected projects. The mode-specific button contract also needs documentation correction. Fix the runtime validation before merging and update the contract documentation.

📝 Info: Scroll index matches original section order

resolveFirstLyricCue sorts sections by start into a new array, but cueSectionIndex uses song.sections.indexOf(cue.section) against the original array, and the grid renders song.sections in that same order (including invalid-start sections). So grid.children.item(cueSectionIndex) targets the correct node with no off-by-one.

Verified — analysis confirms the current behavior is correct, so the index computation is intentionally unchanged, and 8401731 adds a regression test locking this contract in.

Evidence chain:

  1. apps/desktop/src/features/workspace/Workspace.tsx (SongStructure, line 94) renders {sections.map((section, sectionIndex) => ...)} directly over song.sections in original array order — no sorting at render time. Grid children therefore map 1:1 to song.sections positions, including sections excluded from cue resolution by invalid start times.
  2. FirstLyricCueCallout.tsx computes cueSectionIndex = song.sections.indexOf(cue.section) against that same original array, so grid.children.item(cueSectionIndex) resolves to exactly the node rendered for the cue's section. Indexing by the resolver's sorted array would instead target the wrong node whenever render order differs from time order.

New regression test navigates by rendered section position even when analysis start times are unordered (FirstLyricCueCallout.test.tsx): builds sections [NaN-start, start 30, start 5], mounts a grid whose three children each carry their own scrollIntoView spy, clicks the Hear button for the resolved cue (start 5 → "0:05"), and asserts child index 2 (the rendered position of the earliest section) received { block: "nearest", behavior: "smooth" } while children 0 and 1 were never called. A sorted-index implementation would have scrolled child 0 and failed this test.

📝 Info: One-pass interpolation keeps data literal

formatLyricCueCopy runs a single String.replace over the template, so substituted values are not re-scanned and a role name or lyric containing '{section}' renders literally. Correct handling of untrusted analysis text.

No code change needed — the single-pass design is the hardened form, and both the contract comment and a dedicated test already document it.

Why substitution cannot re-enter template syntax: formatLyricCueCopy (FirstLyricCueCallout.tsx lines 25–31) runs exactly one regex pass over the template string only. Replacement text returned by the replacer is never rescanned, so a role name or lyric containing {section}, {role}, {start}, or {lyric} renders as literal text. The function's doc comment states this contract ("Interpolate lyric-cue placeholders once so rehearsal data is never rescanned as template syntax").

Covered by keeps placeholder-looking rehearsal data literal (FirstLyricCueCallout.test.tsx): sets the role name to {section} and asserts the rendered button label contains it verbatim instead of being re-interpolated.

Iterative multi-pass interpolation would reintroduce the injection risk this helper exists to prevent, so I left the implementation unchanged. Happy to revisit if a future interpolator needs nested templates.

📝 Info: Navigation depends on a test-only attribute

The workspace Open action locates the map through document.querySelector('[data-testid="song-structure-grid"]'). A data-testid is a test hook, not a production contract; removing or renaming it silently breaks navigation (it fails closed to no scroll). A stable id or ref would be safer.

중첩 메타데이터를 역참조하기 전에 검증하십시오.

role.cue.kind, section.timeRange.start, section.roles.filter는 컨테이너가 유효하다고 가정합니다. 프로젝트 데이터에 cue: null, timeRange: null, 또는 roles: null이 있으면 FirstLyricCueCallout 렌더링이 예외로 중단됩니다.

레코드와 배열을 먼저 검증한 뒤에 가사, 시간, 역할 우선순위를 확인하십시오. 이 경우 잘못된 섹션 또는 역할은 건너뛰고 null을 반환해야 합니다.

Security Notes: 신뢰할 수 없는 프로젝트 메타데이터의 중첩 필드가 렌더링 경로에서 예외를 발생시키지 않아야 합니다.

동작 모드별 버튼 계약을 기록하십시오.

현재 문구는 가사 큐가 있으면 Hear 버튼을 표시한다고 설명합니다. 실제 구현은 workspace 모드에서 Open 탐색 버튼을 표시합니다. callback-only 모드는 onHearLyricCue가 있을 때만 Hear 버튼을 표시합니다.

문서에 workspace 탐색과 player 재생의 표시 조건을 각각 명시하십시오.

🟡 Duplicate changelog entry for new UI tests

The 0.1.4 changelog line about new UI unit tests is replaced by two lines: one with new '100% 테스트 커버리지' wording and one identical to the original (CHANGELOG.md). The second is a verbatim duplicate describing the same tests.

📝 Info: Armed state gated on navigation success

In workspace-scroll mode rememberHeardCue runs only after a grid child is found and scrolled; a missing grid or section node returns early and keeps body copy. The useEffect deps reset armed state on cue-identity change.

Merged current develop into this branch: resolved shared-file conflicts by including both this feature's first-lyric-cue callout and the newly landed #957 playable-range work (Workspace.tsx keeps both imports; en/ko locales unioned with symmetric keys; AGENTS/CLAUDE/CHANGELOG unioned). No behavior dropped.
