## Why Remote exec-server now needs one executor websocket to serve multiple harness JSON-RPC sessions. Rendezvous routes by `stream_id`, and the exec-server side needs to use the same stable relay frame contract instead of a hand-rolled JSON shape. The relay protocol also needs to make ownership boundaries clear: harness and executor endpoints own sequencing, acks, retries, duplicate suppression, segmentation, and reassembly; rendezvous only routes frames. ## What Changed - Add the checked-in `codex.exec_server.relay.v1.RelayMessageFrame` proto plus generated prost bindings for `codex-exec-server`. - Encode remote harness/executor relay traffic as binary protobuf websocket frames while keeping local websocket JSON-RPC unchanged. - Demux executor-side relay streams into independent `ConnectionProcessor` sessions keyed by `stream_id`. - Add a programmatic `RemoteExecutorConfig::with_bearer_token(...)` constructor for non-CLI callers and integration tests. - Add an integration test that starts the remote executor against a fake registry/rendezvous websocket and verifies two virtual streams share one executor websocket without cross-talk, including per-stream reset behavior. - Document the remote relay envelope, sequence ranges, `ack`/`ack_bits`, and endpoint responsibilities in `exec-server/README.md`. ## Verification - `cargo test -p codex-exec-server --test relay multiplexed_remote_executor_routes_independent_virtual_streams -- --exact` - `cargo test -p codex-exec-server --test relay` - `cargo test -p codex-exec-server` passed outside the sandbox. The sandboxed run hit macOS `sandbox-exec: sandbox_apply: Operation not permitted` in filesystem sandbox tests.
