 | Phase 1 plan | ✅ updated to Path B. T-1.1 now specifies control mode + `%output` parser. Architecture diagram, risks (R4 + R5) added. |

 ## Open questions for next session
 
-- **OQ-1.** Drop the `tree` event from IC-1 ServerToClient, or keep reserved? (Recommendation: drop.)
-- **OQ-2.** Resize message in IC-1? (Recommendation: defer.)
-- **OQ-3.** Should `tmux/manager.ts` use a single long-lived control-mode connection per **server**, or per **session**? The spike used per-session for simplicity. Per-server scales better but is more code. Decide before T-1.1 starts.
+- ~~**OQ-1.** Drop the `tree` event from IC-1 ServerToClient~~ — **resolved**: dropped. IC-1 frozen 2026-05-15.
+- ~~**OQ-2.** Resize message in IC-1?~~ — **resolved**: deferred, fixed 120×40 for v1.
+- **OQ-3.** Should `tmux/manager.ts` use a single long-lived control-mode connection per **server**, or per **session**? The spike used per-session for simplicity. Per-server scales better but is more code. Decide before T-1.1 starts. (Not an IC question — T-1.1 implementation detail.)
 - **OQ-4.** Worker for T-1.0: same `anthropic/claude-sonnet-4-5`, or escalate to a higher-context model since the refactor touches multiple files? (Recommendation: sonnet-4-5 with `context: fresh` is fine for ~500 LoC refactor.)
