Measured

2026-11-01, Antigravity CLI (agy) 1.4.12 (one process), in the Debian 13 (trixie) VM of the Android Terminal app, on aarch64. The VM kernel was 6.12.93-android16-6-g3a7d1771d492-ab16496487-4k. Claude Code 2.1.316 was installed, but no Claude process ran. The probe kit (probes/run.sh) ran one time in full and three times as the guided step permission for agy. It listed names, sizes, times and record types. It read no content. Measured on: real machine (an Android telephone).

What was measured

  1. The parent chain of the agy process was agy -> bash -> ttyd -> pid 1. ttyd had no tty. The terminal variables held only TERM=xterm-256color. No variable named the Android Terminal app.
  2. The command line of the process was only agy. The command ~/.local/bin/agy was the program, not a link.
  3. agy kept its state in ~/.gemini/antigravity-cli/, with the same names as on Linux (x64), macOS and Windows (fact 072). The process held open conversations/<uuid>.db, its -shm and -wal files, and presence/<uuid>.lock, as in fact 028.
  4. The process started at 08:36:54. log/ got the file cli-20261101_083657.log, 3 s later. log/ held one file for each of four starts.
  5. cli.log in the top folder had the same size (24070 bytes) as the newest file in log/.
  6. In the first two guided steps, agy started during the step, after the kit. The kit counted one agy process before the step, but that process was the kit itself: the one-line start ran it as sh -s -- --guided permission agy, and the agent name matched. The kit fix skips the processes that start the kit.
  7. A new agy process opened crashes/crash_<pid>_<uuid>.log with size 0, the new log/ file and a new presence lock, and held them open. No agy crash was seen.
  8. In the second step, the start of agy and the first prompt also changed history.jsonl (one new line), conversation_summaries.db, jetbox_summaries_proto.pb, annotations/<uuid>.pbtxt, cache/onboarding.json, cache/last_conversations.json, updater/update_status.json and last_check.timestamp.
  9. In the third step, with the fixed kit, the kit found the agy process that ran from the second step. During the step, the operator stopped agy and started it again. history.jsonl got a slash_command record and one more record. The new process opened a new crash file, a new log/ file and a new presence lock. The old process had closed its three files.
  10. In each step, the operator asked agy for a file write. In the 30 s after that, each new transcript got two records: USER_INPUT and PLANNER_RESPONSE. No record type showed a wait for a permission dialog. The changed files also held conversations/<uuid>.db, and four transcript files in brain/<uuid>/.system_generated/logs/: transcript.jsonl, transcript_full.jsonl, and one chunk file of each in chunks/.

Mechanism

The Android Terminal app shows the shell of the VM through ttyd, a web terminal. So a reader in the VM finds the terminal from the parent chain (ttyd), not from the environment.

agy on aarch64 Linux keeps the same files as on x64 Linux. A reader of agy state needs no special case for this VM.
