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 stringify produces deterministic JSON string with sorted object keys regardless of key insertion order
- assert stringify handles nested objects and arrays deterministically
- assert stringify supports custom comparison function via cmp option to determine key sort order
- assert stringify throws TypeError on circular structures by default and replaces circular references with __cycle__ when cycles option is true
- assert stringify correctly serializes primitive values, null, and omits undefined or functions in objects while converting them to null in arrays
