How this works

  1. Run the sender on another machine: ./exfilq path/to/file.
  2. Tap “Start receiver” here and point the camera at the terminal QR.
  3. Wait for the loop — the file completes when every sequence number 0..N-1 has been captured at least once.
  4. Verify & download — the SHA-256 is checked against the metadata frame before saving.
