Summary

Long dubbing transcripts require manually finding each tight-fit, overlong, or Fast warning before generating. The transcript toolbar now shows the flagged segment count and Previous issue / Next issue controls that select and reveal each affected row.

Closes #2686.

Changes

  • Navigate timing warnings, translation failures and Fast fallbacks, audio overflows, and QC flags in transcript order, counting each segment once and wrapping at either end.
  • Reach unmounted rows in long transcripts using an immediate virtual-list jump; keep keyboard focus on the navigation button for repeated Enter/Space use.
  • Use saved translation failures for the active language in both navigation and row badges; clear repaired language errors after paste or translation edits while preserving other languages and undo, and disable navigation during running jobs or recovery.
  • Add translations in all 21 renderer locales, update the dubbing guide, and add release notes.

Type

  • ✨ New feature

Testing

All dependencies, builds, and test execution were isolated in Linux Docker containers. Browser scenarios use the existing mocked backend; no model downloads are required.

  • Electron type checks and full renderer/main/shared tests — 4,452 passed, 1 skipped (including individual and bulk saved-translation repairs with undo/redo).
  • Desktop and web production builds; node electron/tests/packaging-contract.mjs (full bun run check:electron passed).
  • bun run test:frontend — 107 passed.
  • Repository policy and dubbing checks — 607 passed (test_changelog_style.py, test_locale_parity.py, test_app_version.py, test_no_hardcoded_cjk.py, test_dub_qc.py).
  • Chromium dubbing smoke test — includes 1,000 transcript rows, offscreen jumps, wraparound, keyboard focus, resolved warnings, active-language translation failures, pasted translation repairs, and disabled states. The new regression fails on unchanged main because the issue controls are missing, and passes with this change. Also checked the controls at 1400px and 1000px viewport widths.
  • New navigation component, translation repair logic, and tests pass lint; git diff --check passes.

Checklist

  • I've tested this locally in Docker.
  • Every commit author has signed the CLA.
  • I've updated relevant documentation.
  • No local machine paths, logs, or personal environment details in this PR.
  • No version or dependency changes.
  • Cross-platform smoke-matrix CI is green (pending CI).

The dubbing toolbar counts flagged transcript segments and provides wrapping Previous issue and Next issue navigation, including to offscreen rows. This helps users find timing, translation, overflow, and QC problems before dubbing. No merge-blocking risk is established by the supplied evidence.

[Medium impact] The reviewed changes appear safe to merge.

Summary

Adds wrapping navigation between flagged transcript rows and uses saved translation failures for the active language.

  • Dubbing transcripts show flagged rows and let reviewers jump between them.
  • Edited translations clear only the errors they repair.

📝 Walkthrough

Walkthrough

The dubbing workspace adds a count of flagged transcript segments and controls to navigate between them. Navigation wraps through the transcript and selects and scrolls to the chosen row. Translation errors are tracked and cleared per language.

Changes

Transcript Issue Navigation

Layer / File(s) Summary
Language-specific translation errors
electron/src/renderer/src/features/dub/transcript-issues.ts, electron/src/renderer/src/features/dub/dub-session.ts, electron/src/renderer/src/features/dub/dub-translation-errors.test.ts
Translation-error lookup supports per-language errors and the legacy scalar field. Translation edits and matched pasted rows clear the affected language’s error. Tests cover error retention, paste matching, and undo and redo.
Issue classification and navigation
electron/src/renderer/src/features/dub/transcript-issue-navigation.tsx, electron/src/renderer/src/features/dub/transcript-issue-navigation.test.tsx, electron/src/renderer/src/i18n/locales/*
The component identifies translation, plan, fit, and QC warnings, counts each affected segment once, and wraps previous and next navigation. Tests cover warning types, transcript changes, language-specific errors, and disabled controls. Locale files add navigation labels.
Transcript integration and validation
electron/src/renderer/src/features/dub/dub-page.tsx, electron/tests/dub-smoke.mjs, docs/electron-dubbing.md, CHANGELOG.md
DubPage connects issue selection to segment selection and centered instant scrolling. The selected row receives aria-current, and translation-error displays use language-aware lookup. Smoke tests cover virtualized rows, focus, navigation states, and language-specific errors. Documentation and the changelog describe the controls.
