DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Precomputed session resolution on resume, gated off

Not switched on
Useful1 Signal2
Sessions not in their notes

Resume can report which session it resolved against an expected id, but the flag is off.

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

Feature flag
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.

This account: off · anonymous baseline: off · compiled default in v2.1.234: on

tengu_hover_rest
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.

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