CLAUDE_CODE_HOVER_REST is checked before the server flag for v5 storage, whose compiled fallback is false.

What

The code selecting the v5 storage backend checks CLAUDE_CODE_HOVER_REST before falling back to the tengu_hover_rest flag, whose compiled fallback is false.

Details
  • The variable is propagated to spawned sessions, so a pinned choice is inherited.
Evidence

let e = V.CLAUDE_CODE_HOVER_REST ?? it("tengu_hover_rest", !1);

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

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.
