What
The short-lived cache holding approved file paths now keeps writes and reads in separate lanes and detects when entries are dropped before use. If too many are dropped, the next file operation fails with "its permission check expired before it ran (too many concurrent file operations). Retry." rather than proceeding without a fresh check.
Details
Always on. The lane holds up to 256 entries and tracks up to 1048576 dropped keys.
The error is retryable, so the operation can simply be run again.
Evidence
its permission check expired before it ran (too many concurrent file operations). Retry.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
