/* Host-side test for the direct-commit apply decision.
|
|
*
|
|
* Every case here is a real failure mode, not a permutation for its own sake.
|
|
* The one that matters most is `recommit_after_success_is_idempotent`: that
|
|
* exact sequence deleted users' uploads in the field and reported
|
|
* `rename -> <dest> failed: No such file or directory` (note the empty
|
|
* source), reproduced on hardware before the fix and again after it.
