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.

HOW- Goal
- verify pkg:npm/ms@2.1.3
- Packages

Contract
- ms parses short and long time unit strings (days, hours, minutes, seconds, milliseconds, weeks, years) to milliseconds
- ms parses negative and decimal duration strings into negative and fractional milliseconds
- ms formats positive and negative millisecond values into short duration strings
- ms formats positive and negative millisecond values into long human-readable duration strings with options { long: true }
- ms returns undefined for invalid formats or strings exceeding 100 characters, and throws a TypeError for invalid types or empty strings
