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.valid validates and parses semantic version strings, returning the normalized string or null for invalid inputs
- semver.satisfies tests whether a version string satisfies a semantic version range specification
- semver.gt compares two versions and returns true if the first version is greater than the second version
