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
- Created
- 2026-08-19T10:31:49Z
Contract
- assert ms parses various time duration strings (milliseconds, seconds, minutes, hours, days, weeks, years) to milliseconds
- assert ms parses fractional time duration strings and decimal strings without leading zero
- assert ms parses negative time duration strings to negative milliseconds
- assert ms parses case-insensitive time units and units with or without spaces
- assert ms formats milliseconds to short duration strings for positive and negative numbers
- assert ms formats milliseconds to long human-readable strings with singular and plural units when { long: true }
- assert ms returns undefined for invalid duration strings and strings longer than 100 characters
- assert ms throws Error when passed empty string or non-string and non-number types
