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 verbose plural and singular duration strings including days, hours, minutes, seconds, and milliseconds
- assert ms parses decimal and negative duration strings with fractional units
- assert ms returns undefined for input strings exceeding 100 characters
- assert ms formats negative millisecond values into short strings and long strings with correct singular or plural unit labels
- assert ms throws an error when passed non-string and non-number types including objects, arrays, booleans, null, and undefined
