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/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; returns `{}` on success and emits `thread/archived`. diff --git a/codex-rs/app-server/src/codex_message_processor.rs b/codex-rs/app-server/src/codex_message_processor.rs index 795723f9d3..079a27dca2 100644 --- a/codex-rs/app-server/src/codex_message_processor.rs +++ b/codex-rs/app-server/src/codex_message_processor.rs @@ -16,6 +16,7 @@ use crate::outgoing_message::ConnectionRequestId;
