What

The bookkeeping for a backgrounding request that arrives during a turn moved from a reference plus a boolean to an object with explicit clear, fork-in-flight and idle-fork-mid-turn transitions, and the turn is now explicitly ended for the tracked message when the fork proceeds.

Details
  • Clearing the conversation now also receives the session hook registry.

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