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.satisfies returns true when a version falls within a simple comparison range or caret/tilde range
- semver.satisfies returns false when a version falls outside the specified range
- semver.satisfies supports logical OR sets of version comparator ranges separated by ||
- semver.satisfies respects options like includePrerelease and loose when evaluating prerelease tags
- semver.satisfies returns false for invalid versions or invalid range strings
