# Q118 gate: the pipe change-monitor retries a folder read before calling it a
# failure -- 3 attempts, 2 s apart, the last code named, and a wake rather than
# a fabricated deletion when every attempt fails.
#
# The artifact under repair is NOT in this repository -- the pipe's monitor lives
# at /root/.hermes/scripts/troupe_pipe_monitor.py because the cron job runs it by
# host path -- so like CHECK-q115 this gate reads a host path. That is stated,
# not hidden (the Q106 host-pin class); moving the monitor into the tree is the
# pipe's decision, not this item's. Everything the gate grades is the deployed
# retry loop itself: the fake `curl` sits at the module's real boundary, so no
# function under test is stubbed.
