Resolve the exact item id first. Fall back to the ACP source id for compatibility with older AIR builds.
Codex can rebuild item ids when it restores a session. Match the persisted message fingerprint and occurrence before the thread fork.
Do not send updates for a fork before the client loads it. Release the Codex app-server writer after thread/fork. This lets AIR load the fork through ACP without a terminal fallback.
