## Why Issue #23214 reports `/ps` showing no background terminals while the status line still says it is waiting for a background terminal. The race is in core: `write_stdin` can poll a process that exits before the response returns. The process manager correctly returns `process_id: None`, but the handler still emitted a `TerminalInteraction` event using the requested session id, causing clients to believe a dead process was still being polled. Fixes #23214. ## What changed - Suppress `TerminalInteraction` events for empty `write_stdin` polls once `response.process_id` is `None`. - Continue emitting interactions for non-empty stdin, even if that input causes the process to exit before the response returns. - Extend the unified exec integration test to assert completed empty polls do not emit terminal interactions. ## Verification - `cargo test -p codex-core --test all unified_exec_emits_one_begin_and_one_end_event` - `cargo test -p codex-core --test all unified_exec_emits_terminal_interaction_for_write_stdin` `cargo test -p codex-core` currently aborts in unrelated `agent::control::tests::resume_agent_from_rollout_uses_edge_data_when_descendant_metadata_source_is_stale` with a reproducible stack overflow.
