Expand the "Test quality" reviewer check: 100% coverage proves lines ran, not
that the feature works the way it ships. Judge sufficiency on two axes —
would the test fail on a regression, and does it exercise the REAL thing
(genuine collaborator, real entry path, verify the world) rather than faking
inputs just enough to cover every line. Call out the specific trap of a
happy-path test that hits a line whose PURPOSE is a mid-flight/error/recovery
scenario it never actually drives — the exact gap a clean-turn "durability"
test would miss.
