Each checkpoint now samples until no new worker has answered for the settle
window, and the growth assertion refuses a worker set that changed between the
warm and after checkpoints instead of comparing only the intersection, so a
leaking worker reached by one checkpoint alone cannot drop out of the gate
On the release gate the e2e tests only see the nginx router, and the chart's
ingress sent /debug/memory/summary to the backend catch-all, so the RSS check
measured the backend pod instead of the gateway workers that serve the failing
requests. Render it as an Exact gateway path next to /test, name the host in the
summary response so workers behind one origin never collide on pid alone, and
key the harness readings by (origin, hostname, pid)
