SEMANTIC MIGRATION VERIFICATION
The rows match.
Does the money?
A migration can pass schema and row-count checks while changing what the data means. Run a real assurance check and inspect the evidence.
What this demonstrates
1. Compare meaning
Declared units and exact monetary mappings are checked against migrated values—not just column types.
2. Trace the decision
Each finding names its obligation and evidence source. Download the input, decision receipt and signed proof.
3. Preserve uncertainty
Matching values remain unresolved when business authority and independent boundary evidence are missing.
The private APX engine runs on the server. Demo signatures demonstrate integrity under a temporary key; they are not independent certification. No result authorizes a real cutover.
