#  brAIn daemon launcher
# ===============================================================
#
#  IMPORTANT: run this from Terminal.app — not from an IDE terminal
#  (VS Code, Claude Code, ...) — or macOS won't attach the
#  Input-Monitoring / Microphone permission prompts to the right app.
#
#  On first launch macOS will ask:
#    - "Terminal would like to monitor your input"   -> Allow
#    - "Terminal would like to access the microphone" -> Allow
#
#  If the prompts never appear:
#    System Settings -> Privacy & Security ->
#      -> Input Monitoring -> enable Terminal.app
#      -> Microphone       -> enable Terminal.app
#
#  Prefer a UI? Run `python -m server.control` and start/stop the
#  daemon from the training console at http://127.0.0.1:8900.
