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.

Contract
- semver validates and cleans version strings with valid and clean, returning formatted versions or null for invalid inputs
- semver evaluates version range satisfaction using satisfies with caret, tilde, and comparison operators
- semver compares version ordering and precedence with compare, gt, lt, and eq
- semver increments version numbers across major, minor, patch, and prerelease identifiers with inc
- semver coerces arbitrary strings into valid semantic versions with coerce and extracts lowest satisfying versions with minVersion
