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. semver parses, validates, sanitizes, and increments semantic version strings across major, minor, patch, and prerelease release types
  2. semver compares semantic version precedence with comparison predicates, sorting, and diff calculation
  3. semver evaluates version satisfaction against complex range expressions and selects minimum and maximum satisfying versions
  4. semver constructs SemVer and Range instances exposing structured version components and comparator sets
