Core concepts
Replay
Understand deterministic repair validation.
Deterministic evidence
Replay validates supported transformations against privacy-safe fixtures. It does not execute arbitrary customer code or call the provider network.
Replay fixtures
Build immutable fixtures from redacted incident evidence.
Seamward materializes representative values from structural shapes, orders fixtures consistently, and hashes the manifest. The dataset records its incident, integration, redaction policy, and evidence count.
Isolation
Run supported transformations without network access.
- Fixtures contain generated representative values instead of customer payload values.
- Supported operations run in a bounded adapter.
- The same dataset and adapter version produce a comparable result.
Validation result
Compare candidate output with the expected result.
Every fixture produces a pass or fail result with stable mismatch paths. Checks can cover status ranges, acceptance, business object type, transformed output, and named assertions.
