/**
* EDGE CASE: Rapid create-update-delete cycle tests coalescing correctness.
*
* When events arrive faster than the queue can process them, coalescing
* determines the final action. This tests the full cycle:
*
* create + update = create (content read at sync time)
* create + delete = noop
*
* So a create-update-delete sequence should coalesce to noop and never
* reach the server at all.
*
* But then a new create follows:
* noop + create = create
*
* The final file should be synced correctly.
