- The open-source record compares the settle snapshot with what the probe
and the IPC capture counted up to the click event, and with the mock
requests between the snapshot and the click stamp. Any change means
background work began during Playwright's actionability checks and
could land in J2, so the iteration is rejected.

measureLaunchJourney may, and J2 must pass false.
