`steer()` attaches a one-shot admission receipt to its exact accepted message. After `agent/step` and asynchronous prompt assembly succeed, the loop commits a stable pending batch as `steering/message`, snapshots derived history, and opens `step/start`; only then does each receipt resolve `admitted` with that turn and step. Later arrivals remain pending. Idle steering enters the ordinary FIFO and uses the first request of its eventual turn as the same admission boundary. A turn-concluding tool result, broad cancellation, disposal, or a claimed idle-steering turn that never reaches a request resolves affected receipts `rejected`; `cancel(..., { keepInbox: true })` and non-terminal routing preserve pending delivery. Open-turn `inject()` still commits after all tool results, including accepted context finalized during an interrupted batch, while steering remains provisional until a request admits it.
Every FIFO acceptance mints an `InboxItemId` and publishes `agent/inbox/enqueue` with the complete occurrence. `updateInbox()` owns the synchronous queued-item boundary: edit freezes replacement content without changing message identity or position, while remove publishes discard. Edit publishes `agent/inbox/update`; steering and claimed occurrences return `not-found`. Claim publishes `agent/inbox/dequeue` and irrevocably removes the live address before prompt admission, so a racing update cannot rewrite durable history; `cancel()` without `keepInbox` publishes `agent/inbox/discard`.
Every FIFO acceptance mints an `InboxItemId` and publishes `agent/inbox/enqueue` with the complete occurrence. `updateInbox()` owns the synchronous queued-item boundary: edit freezes replacement content without changing message identity or position, remove publishes discard, and strict steer transfers the immutable message into an open next-step window as a new steering occurrence. A closed window returns `steer-unavailable` without mutation; pending steering and claimed occurrences return `not-found`. Claim publishes `agent/inbox/dequeue` and irrevocably removes the live address before prompt admission, so a racing update cannot rewrite durable history; `cancel()` without `keepInbox` publishes `agent/inbox/discard`.
