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.NewVersion parses semantic versions and extracts major, minor, patch, prerelease, and metadata components
  2. semver.StrictNewVersion rejects invalid version strings with an error
  3. semver.NewConstraint validates whether semantic versions satisfy range constraints
  4. semver.Version comparisons evaluate relative ordering between release and prerelease versions
  5. semver.Collection sorts a slice of versions in ascending semantic order
