Pull request overview
Adds a new PCSM pytest regression test that attempts to reproduce and validate correct handling of a change-stream “path-collision” update sequence occurring while the target is still in the clone phase.
Changes:
- Introduces a clone-phase timing test that delays cloning via large “filler” collections.
- Applies two ordered updates (
$set arr.0.lastScrapeAt, then$set arr.0 = null) during clone and asserts the final synced document matches. - Runs post-sync data integrity validation and checks PCSM logs for errors.
