 | `GET /v1/author/` | verified session or API key | The authors newest first. Query `q` (name or slug, accent and case insensitive), `page` (default 1), `size` (5, 25, 50 or 100, default 25). Body `{ items, total, page, size }`; a bad query is 400 with the body-mismatch message. |
 | `POST /v1/author/` | owner or admin, session only | Create. 201 with the author. `user_id` links an account that has no author. |
-| `POST /v1/author/me` | any verified session | Create the caller's own author from the display name (or the username). A taken slug gets `-2`, `-3`... silently. |
+| `POST /v1/author/me` | any verified session | Create the caller's own author from the display name (or the username). A taken slug gets `-2`, `-3`... silently. 201 with the author plus `slug_adjusted`: `true` when the stored slug differs from the plain slug of the name (a collision suffix was added), `false` otherwise. No other author response carries this field. |
 | `PATCH /v1/author/{id}` | owner or admin on any author; any verified session on the author linked to it; session only | Edit `name`, `slug`, `bio`, `avatar_id`, `website`, `social_links`, `user_id`. Absent fields are untouched, `avatar_id`, `website` and `user_id` accept `null`, `social_links` is replaced as a whole. `user_id` links or unlinks the account and is owner or admin only. |
 | `DELETE /v1/author/{id}?reassign_to={id\|none}` | owner or admin, session only | 204. An author credited on articles needs `reassign_to`: an author id (that author takes the deleted one's position and is never duplicated on an article) or `none` (the credit is removed). The move and the delete are one transaction. `reassign_to` is ignored when the author has no article. The linked account is untouched. |
