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. MIT-0

Contract

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