tests/mutation_tests.py applies each named mutation from the cut map's
Cut B table to an exact, unique source anchor, runs the one test that
must catch it, restores the file byte-for-byte, and reports kill/survive.
A no-op control (anchor rewritten to itself) proves the read/replace/
restore path is transparent. Covers the four rules whose tests currently
pass: MissingLotIsLoud (indexer and Reachable throw on an absent lot),
MatchingHardpointsShareALot (same lot, not a fresh mint), Brand's and
Materialize's record-key order, and StatsReadTheLot (Evaluate reads the
lot's role fills, QualityForRole's fallback). All 8 mutations (7 rules
+ control) behave as expected.
MaterializedLotsSurviveSaveAndReload and CommitKeepsOnlyReachableLots
are not yet reached: they fail before any mutation is applied, blocked
by the CultLib int2 dictionary-key gap reported in the previous commit
and the landing report.
