> A defect in which invalid data is accepted, transformed or stored without any check noticing.

Record: `architecture:silent-data-corruption`
Kind: anti-pattern
Layer: [Enforcement Core](https://banes-lab.com/records/layer/enforcement-core.md)
Severity: discouraged
Scope: contract_compatibility, correctness_verification
Canonical: https://banes-lab.com/ontology#architecture-silent-data-corruption

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Missing Backpressure](https://banes-lab.com/records/architecture/missing-backpressure.md) and before [Lost Update](https://banes-lab.com/records/architecture/lost-update.md).

## Repair

- Refactored by: validate_at_boundary, add_invariants, add_reconciliation, audit_data_changes
- Detected by: missing_boundary_validation, no_invariant_check, impossible_state_in_database, reconciliation_failures
- Violated by: Accept, transform, or persist invalid data without validation, checksums, invariants, reconciliation, or audit.
- Measured by: invariant violations and reconciliation mismatches
- Enforced by: boundary validation, invariant checks, reconciliation jobs
