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.

Case
HOW- Goal
- Compare and sort versions, find minimum and maximum satisfying versions in ranges, and evaluate range intersection and subset relationships with semver
- Packages
- Created
- 2026-08-18T20:21:09Z
Contract
- assert semver.compare sorts version strings in ascending order and semver.rcompare sorts in descending order with prerelease precedence
- assert semver.maxSatisfying returns the highest satisfying version in a candidate list or null
- assert semver.minSatisfying returns the lowest satisfying version in a candidate list or null
- assert semver.intersects checks if two semver ranges have overlapping satisfying versions
- assert semver.subset verifies if a semver range is entirely contained within another range
