What the cache decided for one run.
Attributes
----------
skipped
Root-relative paths whose items are deselected, sorted.
keys
Every candidate's key, ``None`` where it could not be built.
The run's store writer needs these for the files that RAN.
since
The OLDEST green timestamp among *skipped*, so the reported
claim holds for every file it covers; None when nothing is
skipped.
never_cached
Root-relative Hypothesis files refused for unkeyed randomness.
Each is reported once per run.
