Surviving mutants

Generated by scripts/mutation_survivors.py from the cosmic-ray session databases. One row per surviving mutant: the suite ran that mutated line and no assertion failed.

A survivor is not automatically a bug — see the equivalent-mutant classes catalogued in docs/how-to/mutation-testing.md (type annotations, error-message f-strings, interpreter-detail rewrites). Triage means deciding, per row, whether the mutated behaviour is genuinely indistinguishable or whether nothing tests it.

119 surviving mutants across 1 modules, of which 0 are marked annot — a type annotation rewritten by a BitOr-family operator, which cannot change behaviour. Start with the unmarked rows.
