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 semver.cmp evaluates version relationships using string comparator operators
- assert semver.gtr determines if a version is strictly greater than all versions satisfying a range
- assert semver.ltr determines if a version is strictly less than all versions satisfying a range
- assert semver.toComparators decomposes range expressions into 2D arrays of comparator strings
- assert semver.validRange validates and canonicalizes range strings or returns null for invalid input
- assert semver range functions support options including includePrerelease and loose
