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
- assert semver.valid validates semantic version strings and returns normalized versions or null for invalid input
- assert semver.clean strips whitespace and version prefix characters from version strings
- assert semver.inc increments major, minor, patch, and prerelease version components according to release type
- assert semver.diff identifies the difference category between two semantic version strings or returns null for equal versions
- assert semver.coerce extracts and coerces valid SemVer versions from unformatted strings or returns null
- assert semver.minVersion determines the minimum valid version that satisfies a range expression
- assert semver.satisfies evaluates whether version numbers satisfy caret, tilde, and comparison range expressions with prerelease options
