The queued-mail probe asked whether an unread row existed with a sequence above the outstanding Delivery's highest. Mailbox routing moves rows with `UPDATE ... SET to_handle` and never rewrites `sequence`, so mail released from a settled Dispatch, or from a deferred direct handle, enters the Run mailbox carrying an older sequence. Such a row is unread, not a member of the replayed batch, and genuinely queued behind it -- but the probe reported `queuedMatchingMessages: false`, which renders as no warning at all. A coordinator waiting on a `worker_done` saw a replayed batch and no reason to suspect the message it was waiting for was one ack away. Test membership against the batch's own message ids instead. That is sequence-independent and therefore routing-independent. Both `EXPLAIN QUERY PLAN`s remain indexed SEARCHes, and the id list is bounded by the 50-row batch cap. An empty batch now reports any unread matching mail as queued rather than asserting `false`. Also: - `formatDeliveryAction` renders silence only for an observed `false`; every other value renders "unavailable", matching `formatDeliveryStatus`'s polarity so an off-contract value cannot read as "nothing is queued". - Queued mail is not necessarily newer, so say "Other messages" rather than "Newer messages" in the CLI output, the skill guide, the command spec, and the reliability gate. The old wording restated the assumption that caused the defect.

Features
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
