A dispatch +captures its caller's UI or attachment origin before spawning, reserves under the +same message/configuration admission policy and refuses busy work before a +message append, provider turn or entry. The returned handle observes this exact +exchange. Dropping observation leaves the root-owned producer and reservation +intact; cancellation through an old completed handle reaches no later exchange. + +Every saved message carries an opaque public ID and its origin beside the +conversation-scoped numeric `turn`, and a record missing either is unreadable +rather than assumed. A public message reference binds execution, conversation +and the acknowledged saved ID. External-origin messages preserve +unsent human composer text and held draft ownership; only a UI acknowledgement +clears its exact UI revision. External attribution appears in the existing chat. +Passive observation exposes current public state and subsequent changes without +another prompt or append. Its live terminal index is lost with the owning root; +retained history alone establishes no joined-cleanup result after process loss. + +A failed follow-up makes the whole exchange fail even when an earlier turn +answered. Its safe error retains that earlier answer as partial evidence. A +preview, a successful first turn, idle state and a product verdict inside Output +are distinct from the final exchange result. + Stop ends the asking and nothing else. It cancels the generation in flight, the controls of the response being evaluated and the wait for an entry's outcome, and it stops any turn that would have followed — and it returns only once all of
