docs/api-reference.md (the signal notes and the idle/working rows), and the
wiki's Notifications-And-Approvals, Keeping-Agents-Running and Troubleshooting
pages, plus docs/grok-integration.md, still called Antigravity's working and
idle status unreliable. It now declares a working line and prompt marker like
Codex, OpenCode, Gemini, Pi and OMP, so only Grok stays on generic cues. The
Troubleshooting entry for a session stuck showing busy also says that an
Antigravity session waiting on a shell-command approval shows busy until it is
answered, and the API reference says the same of its idle signal.
