 - `thread/loaded/list` — list the thread ids currently loaded in memory.
 - `thread/read` — read a stored thread by id without resuming it; optionally include turns via `includeTurns`. The returned `thread` includes `status` (`ThreadStatus`), defaulting to `notLoaded` when the thread is not currently loaded.
 - `thread/metadata/update` — patch stored thread metadata in sqlite; currently supports updating persisted `gitInfo` fields and returns the refreshed `thread`.
+- `thread/memoryMode/set` — experimental; set a thread’s persisted memory eligibility to `"enabled"` or `"disabled"` for either a loaded thread or a stored rollout; returns `{}` on success.
 - `thread/status/changed` — notification emitted when a loaded thread’s status changes (`threadId` + new `status`).
 - `thread/archive` — move a thread’s rollout file into the archived directory; returns `{}` on success and emits `thread/archived`.
 - `thread/unsubscribe` — unsubscribe this connection from thread turn/item events. If this was the last subscriber, the server shuts down and unloads the thread, then emits `thread/closed`.

 ### Example: Archive a thread
 
 Use `thread/archive` to move the persisted rollout (stored as a JSONL file on disk) into the archived sessions directory.
