  same isolated app data, same real gemini agent, same missing API key
  server ACP authenticate: Success
  server ACP session/new: Failure: Gemini API key is missing or not configured.
  client: The provider could not create a session after sign-in. Gemini API key is missing or not configured.
  retry: same actionable error; provider remains not authenticated
  vertex-ai method: real ACP authenticate Success, session/new Success, client Signed in

  codex gpt-6.1-sol first turn: ACP verification neighbor OK.
  same-thread follow-up: ACP verification follow-up OK.

agent cleanup caveat:
  unbounded gemini subprocesses stalled during cleanup on main; bounded real executable on both revisions:
  exec timeout --kill-after=2s 30s node <installed-gemini-executable> "$@"
  no protocol responses injected; original session/new errors recorded before process cleanup.

remote checks via blacksmith-check:
