tengu_hover_rest is pinned once per process; the backend it selects is an empty stub, so no path is taken.
The gate that decides whether Claude Code uses its new storage layer, an internal flag named tengu_hover_rest, was previously consulted at each use. It is now read once and pinned for the lifetime of the process, and roughly two dozen storage paths were re-guarded so they check that pin rather than simply acting on a backend handle being passed in. The backend itself is an empty stub in this build, so none of these paths can actually be taken.
- The gate defaults to off, so unmodified installs keep the existing file-based storage.
- A non-boolean value logs "tengu_hover_rest served a ${typeof e}, not a boolean; treating it as off" and is treated as off.
- A later read that disagrees with the pinned answer logs "tengu_hover_rest read ${String(e)} at a second pin in this process; keeping the first decision" and the first answer stands.
- Re-guarded call sites include the auth cache read and delete, plugin marketplace, registry and manifest caches, skills cache, skill and SKILL.md reads, skill writes, the auto-updater lock, transcript cleanup and sidecars, session order, group files and session pins, memory and context loading, agent dispatch writes and mailbox files, task-list writes, quota state, logout, and the message queue swap.
- A stray backend handle can no longer half-activate the new path, and a mid-process flag flip can no longer split one session between the old file paths and the new ones.
- The factory that would construct the new backend returns nothing unconditionally in this build, so no new-format storage is created and no session can run on it regardless of the gate.
tengu_hover_rest read ${String(e)} at a second pin in this process; keeping the first decision, tengu_hover_rest, keeping the first decision, at a second pin in this process; keeping the first decision, read ${String(e)} at a second pin in this process; keeping the first decision
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_hover_rest Off in both readingsThe 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.

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.
