"""Autonomous mode pushes to Google Calendar ONLY after dedup.

Locks in the fix for the duplicate-push bug: the pipeline used to run with
push_gcal=True (pushing ALL plan events) and dedup only afterwards — so every
rolling-window re-run re-pushed already-captured events, directly contradicting
dedup.py's "don't create the same event twice"."""
