writersWithoutBackend: "memory" is accepted but passed by no code here.
The config layer can be put in a mode where saving global or project config returns without touching ~/.claude.json, keeping the change in memory only and logging a warning that it will be replaced the next time a real save or refresh rebuilds config. Entering the mode requires being handed writersWithoutBackend: "memory", which no code in this build passes, so it is reachable only from an embedder.
- Both call sites of the enable path pass only the storage backend and no options object, and the exported setter appears once, at its own definition, with no caller.
- Doubly gated: the branch also needs the new storage backend, controlled by the
tengu_hover_restflag whose compiled fallback is off, overridable with theCLAUDE_CODE_HOVER_RESTenvironment variable. - When it does fire, it emits a
storage_v5_backendcounter with reasonunhanded_config_writer; deleting a project config has a matching in-memory branch.
config: ${t} ran without the storage backend in a process whose config record has no file behind it; the change is in memory only and is replaced when a backend-handed save or refresh rebuilds the config from the record, unhanded_config_writer, ran without the storage backend in a process whose config record has no file behind it, writersWithoutBackend
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.
