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
- subset returns true when the first range is completely contained within the second range
- subset returns false when the first range includes versions outside the second range
- intersects returns true when two version ranges share overlapping versions
- intersects returns false when two version ranges are completely disjoint
- subset and intersects support options like includePrerelease for prerelease range comparisons
