- agent/error: drop the stale "(plus the logger)" claim; the machine only
emits the event.
- agent/inbox/claimed: document that a rejected turn boundary ends the
claimed message without discard or re-emission, and that a later batch
may reuse the turn number.
- steer(): document that a rejected step leaves steering parked until the
next wake.
- Fix stray double-space in the inbox inserted/discarded callbacks.
- Sync core.md/core.zh.md mirrors and regenerate the cordis catalog.
