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 human-readable duration strings with various units (years, weeks, days, hours, minutes, seconds, milliseconds) into milliseconds
- ms parses negative durations and decimal values correctly into negative milliseconds
- ms formats millisecond values into compact short duration strings
- ms formats millisecond values into verbose long duration strings with proper pluralization when long option is true
- ms returns undefined for unrecognized strings or strings longer than 100 characters and throws Error for non-string non-number inputs
