- Finding 1 (saveNote): After a successful save, re-read the canonical list from the backend instead of patching in place. A successful save stamps a new updated_at, and the backend sorts by updated_at descending, so the record's position has changed and positional patching would disagree with what a reload would show. If the re-read fails, keep the save reported as successful and leave the existing list alone.
- Finding 2 (stale notes): Clear notes on projectId change (not only when empty) and on load failure. Previously, switching from project A to project B would leave A's notes on screen until B's fetch resolved, and if a user edited one, A's note would be written into B's notes file—cross-project data corruption. If a load fails, A's notes stay visible under B indefinitely.
- Added four new tests covering these scenarios: projectId change clears old notes, failed load leaves no stale notes, saving a new note ends with the backend's list, and saves re-read the list rather than patching.
