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 semantic version strings, strips leading 'v', and returns null for invalid strings
- semver.compare compares versions returning 0 for equality, 1 when first is greater, and -1 when second is greater
- semver.compare respects major, minor, patch, and prerelease precedence
- semver.sort sorts an array of version strings in ascending semver order in-place
