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 duration strings with various units (years, weeks, days, hours, minutes, seconds, milliseconds) into milliseconds
- ms parses fractional, decimal, negative, and numeric string durations
- ms parses case-insensitive units and handles whitespace between number and unit
- ms returns undefined for invalid duration strings or strings exceeding 100 characters
- ms formats positive and negative milliseconds into short duration strings
- ms formats positive and negative milliseconds into long duration strings when given options { long: true }
- ms throws an Error for invalid input types including empty strings, objects, booleans, and non-finite numbers
