# Q-Blog — Glossary & Domain Canon

_Generated 2025-08-16 23:27Z_

**Name** — The account identity under which blogs are created.  
**Blog** — A container for posts; owned by a Name; has **handle**, **title**, **visibility**.  
**Handle** — Human-friendly unique identifier per Name (slug rules).  
**Post** — Content item; belongs to exactly one Blog (immutable link).  
**Role** — `owner | editor | author`; defines allowed operations.  
**Membership** — Name ↔ Blog relationship with role.  
**Revision** — Monotonically increasing number used for concurrency control.  
**Invite** — Time-limited token that assigns a role on acceptance.

### Invariants

- A Post’s `blogId` does not change after creation.
- (`nameId`, `blogHandle`) is unique.
- All write operations require a role check (server-enforced).

### Identifier & URL Guidance

- Canonical blog URL: `/{nameHandle}/{blogHandle}/…` (conceptual).
- Slugs are normalized to lowercase, ASCII, hyphen-separated; collisions rejected with a helpful message.
