Class BulletinApi

The paged archive over Mongo (realm/kind filtered, recency-desc).

Boot seam (idempotent). A thin warm/activation mirror of the other *Api.boot() call sites — the board itself warms via its manifest postRegister, and the frame fan-out is inline (Phase 3), so there is no event tap to install. Wired from AppBootstrap.run().

Edit an existing bulletin in place (by id), merging patch. Returns the updated Bulletin, or null if no such id.

Publish a new bulletin. The author is resolved from the execution context (the publishing avatar's durable templatePath) — never caller-supplied. Returns the persisted Bulletin.

The live ticker window (pins-first, recency-ordered), optionally sliced.

Retract a bulletin (by id) — a soft delete: the row is kept in Mongo but excluded from the live window. Returns the retracted Bulletin, or null if no such id.

Project a Bulletin to its client-facing BulletinRow wire shape (the news-ticker row). A pure mapping — the single source of the projection shared by the inline frame fan-out (BulletinLogic) and the session-establish window (Avatar.enter). Retracted rows are never passed here (the window/fan filter them upstream); expiresAt === 0 is dropped (never-expires).
