### Suggested Work Units

| Unit | Goal | Likely PR | Focused test command | Runtime harness | Rollback boundary |
|------|------|-----------|----------------------|-----------------|-------------------|
| 1 | Fix all 24 pinned strings across 6 ARB files + static validation | PR 1 (single) | `python scripts/validate_arb_fix.py` (JSON/UTF-8/diff-scope/placeholder/`?`-scan checks) | N/A — static content-only change, no runtime code path affected | `git revert` on the single commit restores all 6 files atomically |

## Phase 1: Content Repair (per-locale edits)

- [x] 1.1 Edit `lib/l10n/app_ar.arb` lines 19/27/34/40: replace `durationHoursMinutesSeconds`/`durationMinutesSeconds`/`durationMinutesOnly`/`durationSecondsOnly` values with pinned `ar` cells (spec Requirement: Native short-form duration abbreviations)
- [x] 1.2 Edit `lib/l10n/app_bn.arb` lines 19/27/34/40: replace same 4 keys with pinned `bn` cells
- [x] 1.3 Edit `lib/l10n/app_hi.arb` lines 19/27/34/40: replace same 4 keys with pinned `hi` cells
- [x] 1.4 Edit `lib/l10n/app_ja.arb` lines 19/27/34/40: replace same 4 keys with pinned `ja` cells (no-space compact notation)
- [x] 1.5 Edit `lib/l10n/app_ru.arb` lines 19/27/34/40: replace same 4 keys with pinned `ru` cells (leading-space short abbreviations)
- [x] 1.6 Edit `lib/l10n/app_zh.arb` lines 19/27/34/40: replace same 4 keys with pinned `zh` cells (no-space compact notation)

Tasks 1.1-1.6 are file-independent and may run in parallel; each is a self-contained exact-string replacement per the design's pinned table, touching no other key.

## Phase 2: Static Validation (sequential, depends on Phase 1)

- [x] 2.1 Parse all 6 `app_{ar,bn,hi,ja,ru,zh}.arb` files as JSON (`json.load`); assert success (spec: File integrity preserved)
- [x] 2.2 Decode each file's bytes as strict UTF-8; assert no `�` replacement characters present
- [x] 2.3 Run `git diff --stat` and per-line diff; assert exactly 24 changed lines total across the 6 files, additions == deletions, and no key outside the 4 duration keys per file differs (spec: Unrelated keys are untouched)
- [x] 2.4 Scan the 24 target string values for literal `?`; assert zero occurrences (spec: No residual corruption markers)
- [x] 2.5 Regex-extract `{...}` placeholder tokens from each of the 24 fixed values; assert each matches expected `{hours}`/`{minutes}`/`{seconds}` set/order and that `@durationXxx.placeholders` metadata blocks are byte-unchanged (spec: ICU placeholder integrity)
- [x] 2.6 Assert each of the 24 fixed values is byte-identical to its pinned spec-table cell (spec: Each of the 6 locales matches its pinned string exactly)
- [x] 2.7 Run `git diff --check` to confirm no whitespace/EOL damage

Do NOT run `flutter build`, `flutter gen-l10n`, `dart analyze`, or `flutter analyze` — these hang in this environment.
