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.

- 2026-08-19T09:14:12Z
Contract
- assert semver.cmp evaluates relational operators between versions including greater than, less than, and equality
- assert semver.cmp distinguishes strict identity === and !== with build metadata from semantic equivalence == and !=
- assert semver.cmp throws a TypeError when given an invalid comparison operator
- assert semver.toComparators parses hyphen ranges and caret ranges into disjunctive normal form comparator sets
- assert semver.toComparators expands multiple range alternatives into separate comparator arrays
- assert semver.toComparators throws a TypeError when provided an invalid range string
