* Standalone, `localStorage`-backed boolean atom kept separate from
|

* `state/settings.ts` on purpose. When `true`, encrypted-room search persists a

|
* decrypted plaintext index to IndexedDB (`lotus-search-cache`) so coverage

|

* explicitly opted into; the cache is clearable from the search UI and wiped on
|

|
|
* logout. Toggling this atom off stops all reads/writes but does NOT wipe
|
||
|
|
* existing data — that is the explicit "Clear cached index" button / logout.
