# Supervisor controller for the operatorstack/interlock public projection.
#
# The publish pipeline is otherwise open-loop: interlock-publish.yml fire-and-forgets
# a sync dispatch and the public repo self-heals on a 6-hourly cron. If any link
# breaks (token, dispatch, stale-guard, un-merged sync PR, red downstream verify) the
# public repo silently goes stale and nothing here ever fails. This workflow closes
# the loop by asserting the invariant `operatorstack/interlock == project(main)`:
#
#   verify (Boundary B) — on push to main touching the lab: poll until the public
#     repo carries this projection, so a broken sync surfaces within minutes.
#   drift  (Boundary C) — scheduled/manual: assert parity + control-plane sync in a
#     single shot; the deterministic backstop that also catches out-of-band drift.
#
# Both fail CI and open/refresh a `projection-drift` issue when the public repo lags.
# This is NOT a generated file (it is hand-maintained like interlock-lab.yml).
