projects added using add project > local folder; threads and turns submitted through browser UI with codex gpt-6.1-sol.

runtime check imports production buildRemoteNodeEnvScript, runs its emitted remote_node_satisfies_engine shell function against the actual installed node. no mocked versions, fixtures or provider responses.
this check runs through the real browser -> websocket -> orchestration -> codex -> terminal tool path; it does not initiate a desktop ssh connection.

head github CI: all reported checks pass or skip, no failure/pending.

not verified: desktop ssh connection lifecycle, WSL, mobile/native clients, remote/relay/tunnel modes, provider compatibility manifest ingestion. the browser client exposes no engine-range setting; WSL needs Windows. provider policy validation separately tokenizes ranges before this helper, so this check does not establish spaced-range support at that ingress.
