design-dev's two follow-up commits on the R2 branch.
167f265 is PRE-EXISTING and his to have found, not his to have caused:
Path.is_file() swallows ENOENT but PROPAGATES EACCES, so one folder with r--
and no x in one booth made booth_items raise — and list_booths calls it for
every booth, so the index 500s for all of them. Identical blast radius to the
0xff filename the bug-hunt panel found, arriving through a different syscall.
39a3cb2 commits R2's own falsifiers as tests/mutations/r2_flow.toml, 18 rows.
Its first run caught three vacuous proofs, which is the fourth time this week
that running the mutation has disagreed with reading the assertion.
