Each returned `thread` includes `status` (`ThreadStatus`), defaulting to `notLoaded` when the thread is not currently loaded. - `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/remember` — silently copy context from one or more previous threads into an idle loaded target thread. The request is all-or-nothing: `sourceThreadIds` must be non-empty, cannot include the target thread, and every source rollout must be readable from active or archived sessions. On success it persists one hidden remembered-context packet in the target rollout, emits no turn notifications, and returns `{ rememberedThreadIds, contextPreview }`. +- `thread/remember` — silently copy context from one or more previous threads into an idle loaded target thread. The request is all-or-nothing: `sourceThreadIds` must be non-empty, cannot include the target thread, and every source rollout must be readable from active or archived sessions. On success it persists one hidden remembered-context packet in the target rollout, labels remembered conversations with their stored thread titles when available, emits no turn notifications, and returns `{ rememberedThreadIds, contextPreview }`. - `thread/metadata/update` — patch stored thread metadata in sqlite; currently supports updating persisted `gitInfo` fields and returns the refreshed `thread`. - `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;
