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.ltr('0.9.0', '^1.0.0') === true
- semver.ltr('1.2.0', '^1.0.0') === false
- semver.ltr('0.9.0', '1.0.0 - 2.0.0') === true
- semver.ltr('1.5.0', '1.0.0 - 2.0.0') === false
- semver.ltr('0.5.0', '>=1.0.0 <2.0.0') === true
- semver.ltr('1.0.0', '>=1.0.0 <2.0.0') === false
- semver.ltr('0.8.0', '~1.2.0') === true
- semver.ltr('1.2.5', '~1.2.0') === false
- isVersionLessThanRange wrapper correctly determines if version is less than range
