* Desktop Mode — Pinned notes REST routes. |
| 4 |
* |
| 5 |
* Routes under `/desktop-mode/v1/notes`: |
| 6 |
* |
| 7 |
* GET /notes List the viewer's own notes |
| 8 |
* (private + publish) plus every |
| 9 |
* other user's public notes. |
| 10 |
* POST /notes Create a note (author = viewer). |
| 11 |
* PATCH /notes/(?P<id>\d+) Partial update — owner only. |
| 12 |
* DELETE /notes/(?P<id>\d+) Soft-trash — owner only. |
| 13 |
* POST /notes/(?P<id>\d+)/restore Untrash (Undo toast) — owner only. |
| 14 |
* POST /notes/(?P<id>\d+)/convert Spawn a draft post from the note, |
| 15 |
* then trash the note — owner only, |
| 16 |
* requires the `edit_posts` cap. |
| 17 |
* |
| 18 |
* Ownership model: a note belongs to its `post_author`, and ONLY the |
| 19 |
* owner may mutate it — deliberately including administrators. Public |
| 20 |
* notes are a read-only broadcast surface; "manage other users' |
| 21 |
* notes" is not a supported operation through this controller. |
| 22 |
* |
| 23 |
* Optimistic concurrency: PATCH accepts an `updatedAtMs` field |
| 24 |
* carrying the client's last-seen modified timestamp; a mismatch |
| 25 |
* returns 409 `desktop_mode_notes_conflict` with the server copy in |
| 26 |
* `data.current` so the client can re-render instead of clobbering. |
