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.compare and comparison helpers evaluate relative precedence between semantic versions
  2. semver.sort and semver.rsort sort arrays of version strings in ascending and descending order
  3. semver.valid and semver.clean validate and sanitize semantic version strings
  4. semver.satisfies evaluates whether a version satisfies caret, tilde, and comparison ranges
  5. semver.coerce extracts and coerces valid SemVer versions from arbitrary loose string inputs
  6. semver.minVersion resolves the minimum version that can satisfy a given range
