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.compare returns 0 for equal versions, 1 when first version is greater, and -1 when first version is lower
- semver.compare correctly evaluates major, minor, patch, and prerelease precedence
- semver.rcompare sorts semantic versions in descending order
- semver.compareBuild evaluates build metadata differences when version numbers are identical
- compareVersions helper function validates version comparison and sorting
