Server can now push a "your memory context was withheld" notice

Memory

The server can tell Claude your memory context is being withheld, though memory context itself is off.

A withheld-memory-context live event is handled end to end but the store behind it needs tengu_misty_anchor.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

What

The cloud connection gained a new live event type that tells Claude Code whether the server is withholding your memory context. The handling is wired end to end: a withheld notice drops the cached context, anything else triggers a re-fetch. The store it feeds is behind the same tengu_misty_anchor and entrypoint switch as the rest of memory context, so on a build without that turned on, nothing is fetched even when the event arrives.

Details
  • The transport gained a field and a setOnMemoryContextStatus setter next to its existing heartbeat probe, and the event dispatcher routes the new frame to it carrying whether the payload marked the context withheld.
  • With the gate off, the receiving handler returns early after clearing the cache.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
