+## Representative blog (scoped to one representative)
+
+A representative (`ROLE_REPRESENTATION`) manages their own posts for their own domain. They see and edit **only their own** posts, and may target **only cities within their coverage** (`representation.cities`). Admin CRUD (`/api/v1/blog*`) is unaffected — an admin still sees everything.
+
+| Route | Method | Path | Permission |
+|-------|--------|------|------------|
+| list own | GET | `/api/v1/representation/blogs` | `ROLE_REPRESENTATION` (`page`,`limit`,`status`) |
+| create | POST | `/api/v1/representation/blog` | `ROLE_REPRESENTATION` |
+| update own | PATCH | `/api/v1/representation/blog/{uuid}` | `ROLE_REPRESENTATION` |
+| delete own | DELETE | `/api/v1/representation/blog/{uuid}` | `ROLE_REPRESENTATION` |
+
+- On create, `author` = the representative's user and `representation` = their record (set server-side).
+- `city_id` **must** be one of the representative's coverage cities, else `422`. A post that isn't owned by the caller returns `404` (never leaked).
+- The request body accepts the same core + SEO + scheduling fields as the admin create.
+- The blog `toArray`/`toListArray` includes `representation` (`{ uuid, name, domain }` or `null`).
+
+### Errors
+| Code | HTTP | Description |
+|------|------|-------------|
+| `ERR_AUTH_006` | 403 | Not a representative / no representative profile |
+| `ERR_NOT_FOUND_001` | 404 | Post not found or not owned by the caller |
+| `ERR_VALIDATION_002` | 422 | Missing title/body, unknown city, or city outside coverage |

+## Scheduled publishing
+
+`scheduled_at` (unix) drives automatic publishing. A scheduler task (`PublishScheduledBlogsMessage`, every 1 minute via `symfony/scheduler`, consumed by `messenger:consume scheduler_default`) publishes every `draft` whose `scheduled_at <= now` **and** whose `review_status` is `null` or `approved`. A `pending_review` post is never auto-published — the medical-review gate wins over the schedule.
+
+---
+
 ## Medical-review gate
 
 The content pipeline (`clinicpro-crawler/content/`) generates Persian health articles as **drafts** (`status=draft`, `review_status=pending_review`). A doctor/admin then approves or rejects each one before it goes public. The reviewer's identity is stored and shown on the post — the E-E-A-T signal for YMYL content. `review_status=null` posts (created manually by an admin) are outside this gate.
