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
- assert ms parses human-readable duration strings with diverse time units (days, hours, minutes, seconds, milliseconds, weeks, years) into millisecond numbers
- assert ms parses negative duration strings and decimal duration values into correct millisecond numbers
- assert ms parses case-insensitive time units
- assert ms returns undefined for invalid duration string formats and strings exceeding 100 characters
- assert ms formats millisecond numbers into short human-readable duration strings
- assert ms formats millisecond numbers into long human-readable duration strings when long option is enabled
- assert ms formats negative millisecond numbers into negative short and long duration strings
- assert ms throws a TypeError or Error for non-string non-number inputs, empty strings, and special non-finite numbers like NaN and Infinity
