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.

- 2026-08-19T07:20:50Z
Contract
- assert ms parses time strings with various units (years, weeks, days, hours, minutes, seconds, milliseconds) into milliseconds
- assert ms parses decimal and leading-dot duration strings
- assert ms parses negative duration strings and case-insensitive unit representations
- assert ms returns undefined for unrecognized strings and strings exceeding 100 characters
- assert ms formats milliseconds into short duration strings
- assert ms formats milliseconds into long human-readable strings with singular and plural units when long option is true
- assert ms formats negative millisecond values in both short and long modes
- assert ms throws an Error for empty strings, non-string, non-number, and non-finite inputs like objects, arrays, booleans, null, undefined, NaN, and Infinity
