# ARIS-Monitor launcher.
#
# READ-ONLY MONITOR. This launcher starts a Python program that only READS
# files under ~/.claude. It never writes to / kills / signals / spawns against
# any of your sessions or processes, and makes no network calls.
#
# ARIS-Monitor has ZERO third-party dependencies -- it uses only the Python 3
# standard library (tkinter ships with the interpreter). So there is nothing to
# pip-install. We deliberately do NOT create a venv: a fresh venv frequently
# lacks the compiled `_tkinter` module that the base interpreter has, which
# would break the GUI. We just verify Tk against your existing python3 and run.
#
# Usage:
#   ./run.sh            # start the floating widget (falls back to the ticker
#                       # if Tkinter is unavailable)
#   ./run.sh --ticker   # force the headless terminal ticker
#   ./run.sh --check    # read-only smoke test (scanner.py), then exit
#
