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.subset returns true when a narrower range is a subset of a broader range
- assert semver.subset returns false when the sub-range contains versions outside the parent range
- assert semver.subset correctly compares bounded ranges and hyphen ranges
- assert semver.subset supports the includePrerelease option for prerelease ranges
