ReplayGate
Interactive labRe-runs sealed evidence packs to detect verification drift over time.
What it checks
- Deterministic reproduction of a sealed pack
- Drift detection between runs
- Tamper detection
What it does not check
- It proves a result reproduces. It does not prove the result was right.

Deterministic Evidence Lineage Architecture
The underlying evidence changed. What does that affect?
DELA detects changes in scientific, operational or other source evidence, traces the affected dependencies, preserves the work that remains valid, selectively replays reproducible operations, and routes non-reproducible work to qualified human review.

Evidence
Every verdict leaves a record
| Property | Behaviour |
|---|---|
| Determinism | The same input produces the same verdict. A result that does not reproduce is treated as a defect. |
| Signing | Verdicts are Ed25519 signed and anchored in a tamper-evident chain. |
| Replay | A sealed pack can be re-run later to detect verification drift. |
| Availability | Fail-closed. If this gate cannot be reached, the result is recorded as unavailable, never as a pass. |
| Independence | A third party can verify a pack without our source code and without contacting us. |
