about

nx_cms_migrate_exceed_gate.nx -- W-RE-004 head-to-head EXCEED (import-export-migrate, INTEGRITY axis). Runs BOTH importers on the SAME corpus of bundles (pristine + byte-tampered): OURS = cms_migrate_import (sha256-verifies the body before accepting) INCUMBENT = a no-integrity importer (strip header, copy body, never verify) -- the CWE-494 failure mode of migration tools that import without an integrity check (silent corruption). Ground truth: a pristine bundle SHOULD import; a tampered bundle SHOULD be refused. Verdict COMPUTED by nx_cms_exceed. Writes CMSEXCEED feature=import-export-migrate axis=integrity to cms_exceed.log on a measured AHEAD + referee-clean + anti-false-green self-tests. license_tier: ORIGINAL
