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.valid returns cleaned version string or null for invalid semver input
  2. semver.clean trims whitespace and strips leading v or = characters
  3. semver.satisfies matches versions against caret, tilde, and comparison ranges
  4. semver.compare returns -1, 0, or 1 comparing version precedence
  5. semver.diff identifies release difference type between two versions
  6. semver.inc increments version according to release type and optional prerelease identifier
  7. semver.coerce extracts and coerces version numbers from arbitrary strings
  8. semver.prerelease returns array of prerelease components or null if none exist
