What

The new v5 storage backend for credentials and settings can now be pinned with the CLAUDE_CODE_HOVER_REST environment variable, which takes precedence over the tengu_hover_rest server flag. That flag's built-in fallback is false, so the v5 backend stays off unless the server enables it or you set the variable.

Details
  • The decision is now latched once per process instead of re-read at each call site; the code warns if a later pin disagrees with the first.
  • The variable was added to the list of CLAUDE_CODE_* names forwarded to spawned sessions alongside CLAUDE_CODE_REMOTE_SESSION_ID, so a pin carries into child sessions.

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.
