POST /x402/v1/lockfile-change-report
live
Compare two lockfiles and report what a manifest diff cannot see. Reports newly installed transitive packages, resolved version moves with breaking risk, a registry that changed, and the most serious finding available here: the same version with a different integrity hash, meaning the artifact behind a version that was supposed to be immutable is not the one that was there before.
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
