Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- assert encoding existence checks return true for supported legacy encodings and false for unknown encodings
- assert Korean EUC-KR encoding and decoding roundtrip preserves original text and produces valid byte buffer
- assert Japanese Shift_JIS encoding and decoding roundtrip preserves original multibyte text
- assert Cyrillic Windows-1251 encoding and decoding roundtrip preserves original text accurately
- assert UTF-8 encoding with addBOM prepends byte order mark 0xEF 0xBB 0xBF and default decoding strips BOM while explicit option retains BOM
- assert stateful chunked decoder correctly decodes multibyte character stream split across chunk boundaries
