  "note": "The live-push half of the agentapi capture, run by the operator on Antigravity CLI 1.2.7, macOS arm64, 2026-09-21. Step 1: in an interactive TUI opened in a probe project, the operator had the agent run one script from its own shell and approved it at the permission prompt; the script wrote the session's endpoint to a 0600 file and printed variable names only. Step 2: a separate process loaded that endpoint only inside subshells, asked the idle session's language server to deliver one message, watched the transcript, and deleted the endpoint file. Every value printed passed through a mask that replaced the exact token; no credential value was recorded anywhere. Conversation and initialization ids are redacted.",
