-The experimental Agent Teams plugin sends new messages directly to the target Agent inbox instead of retaining a separate Team mailbox. `send_message` returns only `messageId`; it no longer returns an `accepted` or `queued` status. Acceptance does not confirm model processing or a synchronous storage flush. Failed sends are not retained for retry, and explicit resends are not deduplicated.

 ### What success and failure look like
 
-Sending a message succeeds as soon as it is safely stored: the result is `accepted` (delivered now) or `queued` (waiting), and a queued message must not be resent. `wait_agent` returns `noProgress` right away when no other member is running or provisioning, telling the caller to wake a teammate first; otherwise it waits for the next change and the caller re-reads state afterward. Task edits based on an outdated revision are rejected rather than overwriting newer work.
