| 5 |
* Three endpoints under `desktop-mode/v1/content-graph`: |
| 6 |
* |
| 7 |
* GET /post-types |
| 8 |
* Lists the types eligible for the graph (`slug`, `label`, `icon`, |
| 9 |
* `count`, `taxonomies`). |
| 10 |
* |
| 11 |
* GET /nodes?types=post,page,... |
| 12 |
* Returns the full `{ nodes, edges, groups, stats }` tuple. Cached |
| 13 |
* server-side, see graph-builder.php. `types` omitted means every |
| 14 |
* registered type; `types=` (present but empty) means none — the |
| 15 |
* shell sends the latter when every toolbar chip is off. |
| 16 |
* |
| 17 |
* GET /post/<id> |
| 18 |
* Returns the side-panel detail bundle for one post: |
| 19 |
* { post: {...}, author, contributors, comments, categories, |
| 20 |
* attached_media, revisions }. |
