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.satisfies verifies whether a semantic version satisfies a range expression with optional prerelease inclusion
- assert semver.validRange parses and normalizes range expressions into canonical comparator sets or returns null for invalid input
- assert semver.minVersion calculates the minimum semver version that can satisfy a given range expression
- assert semver.toComparators decomposes range expressions into a two-dimensional array of comparator strings in disjunctive normal form
- assert semver.Comparator instantiates comparator objects with operator, value, and semver properties and tests matching versions and intersection
- assert semver.Range parses complex multi-comparator expressions into sets of comparators, formats canonical ranges, and tests version membership
