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
- ms parses short duration strings with various units to milliseconds
- ms parses long duration strings with plural units to milliseconds
- ms parses decimal duration strings to milliseconds
- ms parses negative duration strings to negative milliseconds
- ms formats milliseconds to short duration strings
- ms formats milliseconds to long duration strings with long option
- ms formats negative milliseconds with negative sign
- ms returns undefined for invalid unparseable duration strings
