 Automatic work never delays the main agent response. A provider starts only after a marked loop-built request's exact route matches the current logged `request/header`, including when the unchanged header needs no new snapshot. Its late completion appends a standalone log-only event directly through `Session` without opening a turn. Persistence observes that event eagerly and drains on ordinary lifecycle checkpoints; title publication itself does not force a flush. Automatic failures warn and retain the latest title. New all-message revisions, provider disposal, session disposal, and explicit refresh abort older work, and a stale completion cannot append. Concurrent explicit refreshes reserve their revision before provider work, while overlapping automatic and explicit fallback requests share one session-local in-flight append. The service and bundled model provider each append their own literal event type, so no generic title-write marker, cast, or settlement queue is needed. Service teardown cancels queued work and drains calls that ignore cancellation before unloading completes.
 
-Forks inherit title events in their seed unchanged. The first-message cadence does not automatically retitle a child; the all-messages cadence may append a new revision after the child receives a later human prompt.

 ## Provider contract
 
-A provider supplies a branded stable id, automatic mode (`first-message` or `all-user-messages`), and `generate(request)`. The request carries the live session, all eligible messages through one fixed revision, the current logged main-request route when available, and cancellation. The result identifies a non-empty title, unique ordered source-message seqs from that request, and the optional provider/model route used to generate it. The service normalizes and validates the result before it becomes durable.
