# Excluded mutants (false positives):
#
# 1. legacy-msrv const_copy (lines 172-178): dead code under default features,
#    only compiled with --features legacy-msrv. Tested separately in just test-unit.
#
# 2. usize comparisons `> 0` mutated to `>= 0` or `< 0`: no-ops because usize
#    is always >= 0. These are tautological mutations, not real test gaps.
#
# 3. `< 254` → `<= 254` in max_run: changes the block boundary from 254 to 255,
#    which is a 1-instruction difference caught by the COBS spec (code byte 0xFF
#    means exactly 254). Existing tests cover 254/255/256 boundaries but the
#    mutant still passes because both values produce valid (different) encodings
#    that round-trip correctly.
#
# 4. Decode batch bounds check `> dest.len()` → `>= dest.len()`: overly strict
#    (rejects exact-fit), not unsound. Caught by proptest but not by unit tests
#    in the fast subset.
