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.

Case
HOW- Goal
- verify pkg:npm/ms@2.1.3
- Packages
- Created
- 2026-08-19T08:03:28Z
Contract
- assert ms parses duration strings with various units (years, weeks, days, hours, minutes, seconds, milliseconds) into numeric milliseconds
- assert ms parses decimal, negative duration strings, and suffixless numeric strings
- assert ms returns undefined for invalid formats, unrecognized units, and string inputs exceeding 100 characters
- assert ms formats numeric milliseconds into concise short duration strings
- assert ms formats numeric milliseconds into expanded long human-readable strings with singular and plural units
- assert ms formats negative millisecond durations in both short and long modes
- assert ms throws an Error when invoked with empty strings, non-string/non-number types, NaN, or Infinity
