- Server /tasks/:id/diff and /tasks/:id/file-diffs now both use
resolveDiffBase() for consistent file lists across card and modal
- Both endpoints handle done tasks via mergeDetails.commitSha,
returning structured { files, stats } from the merge commit
- TaskChangesTab uses fetchTaskDiff for all columns (no more
fetchCommitDiff/parsePatch client-side path for done tasks)
- useChangedFiles hook simplified — server handles done tasks
- Done task cards show "N files changed" button using mergeDetails
- Updated tests for new unified data flow
