+| Upstream                                               | Subject                                                    | New SHA     |
+| ------------------------------------------------------ | ---------------------------------------------------------- | ----------- |
+| [#2364](https://github.com/pingdotgg/t3code/pull/2364) | fix(release): use configured node for smoke manifest merge | `2f1e3cc3c` |
+| [#2372](https://github.com/pingdotgg/t3code/pull/2372) | Ignore stale WebSocket lifecycle events after reconnect    | `b408a6857` |
+
+**Conflict resolutions applied:** None — both upstream commits cherry-picked cleanly. Patch context for `wsTransport.ts` / `protocol.ts` / `wsTransport.test.ts` matched MarCode HEAD exactly; only delta is the rebrand strings (`@marcode/contracts`, `"Unable to connect to the MarCode server WebSocket."`), untouched by upstream. `release-smoke.ts` line 260 matched at offset (file is shorter in MarCode because of the removed nightly-channel block, but the heredoc context is identical).
+
+**Note on upstream's new `isActive` socket-session gate:** The new `WsProtocolLifecycleHandlers.isActive?` callback in `protocol.ts` lives at the **socket session** layer (per-session id check inside `WsTransport.createSession`). It is distinct from the existing **per-stream** `isActive` parameter on `runStreamOnSession` in `wsTransport.ts` — they don't collide functionally but a future reader could conflate them.
+
+**Bundled non-upstream commit (out-of-cycle, co-shipped):** `ef574febf feat(provider): subagent task events, cursor allow_once, ACP outgoing logging` — backfill subagent test coverage for `7f04a4a11` (`task.progress` with `lastToolName` / `summary`, child-thread delta suppression), Cursor `allow_once` preference for auto-approval (preserves command-text visibility against the empty-`rawInput` Cursor server bug), and `effect-acp` `sendNotification` rewired through `logProtocol` + JSON-RPC encoding to match request/response paths.
