Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🟡 Moderate · up to This change adds default-on task-start and per-write restore points, but failed baseline saves can permanently suppress recovery and non-awaited saves can merge or omit restore points during closely sequenced edits. These bounded rollback and data-retention risks should be fixed or explicitly accepted before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

In `@packages/types/src/global-settings.ts`:
- Around line 102-107: Remove the duplicate provider-local
DEFAULT_PER_WRITE_CHECKPOINTS declaration in ClineProvider and import the shared
constant from global-settings.ts. Update its usages to reference the imported
symbol so schema, provider state, and webview share one default value.
In `@src/core/task/__tests__/Task.spec.ts`:
- Around line 3292-3333: Add a focused test in the “task-start baseline (B1
perWriteCheckpoints)” suite where mockProvider.getState() resolves without the
perWriteCheckpoints property, then abort before initiateTaskLoop and assert
checkpointSave is called exactly once with false and true, matching the
enabled-case behavior.
In `@src/core/tools/ApplyPatchTool.ts`:
- Around line 136-141: The checkpoint block in execute must run only when the
entire apply_patch operation succeeds; propagate handler success through the
approval and local-write paths, or return immediately on the first unsuccessful
file operation, before calling checkpointSave. Preserve the existing
perWriteCheckpoints setting behavior and add a regression test covering rejected
approval with no checkpoint recorded.
In `@src/core/webview/__tests__/ClineProvider.spec.ts`:
- Around line 1419-1434: Add an explicit false-value test alongside the existing
getStateToPostToWebview tests: set perWriteCheckpoints to false through
contextProxy, call getStateToPostToWebview, and assert state.perWriteCheckpoints
is false, while preserving the existing true and unset-default coverage.
In `@webview-ui/src/i18n/locales/ca/settings.json`:
- Around line 705-707: Translate the checkpoints.perWrite label and description
from English in webview-ui/src/i18n/locales/ca/settings.json lines 705-707,
de/settings.json lines 705-707, es/settings.json lines 705-707, fr/settings.json
lines 705-707, hi/settings.json lines 705-707, id/settings.json lines 705-707,
it/settings.json lines 705-707, and ja/settings.json lines 705-707, using the
appropriate language for each locale while preserving the existing keys and
meaning.
