Precomputed session resolution on resume is behind tengu_hover_rest, which defaults off.

What

Resuming a session can now hand in a callback that reports which session was resolved, checked against an expected session id. It is behind the tengu_hover_rest flag, which defaults to off, and is skipped when you are forking a session rather than resuming one.

Details
  • Nothing in this build turns the flag on, so whether it runs is decided by server-side configuration.

tengu_hover_rest Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

What has happened since
Flag reading moved The flag server now returns off for tengu_hover_rest, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
