Review Op — test coverage
Thin entry point. Run python3 tools/review_op.py <Operator> --domain test and interpret
per the test section (TST-*) of .agents/guidance/REVIEW_OP_GUIDELINES.md: independent gold,
required cross-layout parity, axis-coverage mirror, negative tests, tolerance discipline (bit-exact by
default), and the Python API surface. Resolve MANUAL items at the cited locations. When
fixing (--fix), author the missing positive, negative, or layout-parity cases - never introduce
or widen a tolerance silently (emit rationale + needs-human) — and re-run to confirm.
Findings-first.
