## Summary - add an `EncodedFrame` type so IPC payloads are serialized and size-checked before entering bounded queues - add the V1 `operation/cancel` client-to-host message - pin the new wire shape with protocol tests ## Why The process-owned code-mode host needs bounded, pre-encoded outbound messages and a best-effort cancellation signal. Keeping these wire primitives in a protocol-only change lets their compatibility contract be reviewed independently from either endpoint. ## Stack This is **1 of 4** in the process-owned code-mode session stack. The next PR targets this branch. ## Validation - `just test -p codex-code-mode-protocol` — 22 passed - `just fix -p codex-code-mode-protocol` - `just fmt`
