MAJOR from the 2026-04-22 review (database.rs:389-449):
complete_subtask_and_check_parent auto-completes a parent task when
the last child completes, but uncomplete_task only flipped the
requested row — reopening a child left the parent wrongly marked
done, breaking the "parent done iff every child done" invariant.
Wraps uncomplete_task in a transaction and, after flipping the
subtask, looks up its parent_task_id. If present, resets the
parent to done=0 as well. Scoped to "done=1" on the parent update
so an already-open parent is untouched.
Two regression tests:
- uncomplete_subtask_reopens_auto_completed_parent: the direct
mirror of the existing subtask_crud_roundtrip completion flow.
- uncomplete_top_level_task_does_not_touch_siblings: ensures the
parent-reopen branch is a no-op for tasks with no parent, and
siblings without a parent relationship are unaffected.
