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
- ms parses string durations like '2 days', '1d', '10h', '1m', '5s' to milliseconds
- ms parses negative duration strings like '-3 days' and '-1h' to negative milliseconds
- ms formats milliseconds to compact duration strings like '1m' and '2m'
- ms formats milliseconds with long option to human-readable strings like '1 minute' and '2 minutes'
- ms returns undefined for unparseable duration strings
- ms throws Error for empty string or invalid input types
