# Replay Instructions
|
||||
|
||||
This document provides instructions for replaying the verdict verification for artifact `{digest}`.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Stella CLI v2.5.0 or later
|
||||
- Network access to policy engine (or offline mode with bundled policy)
|
||||
|
||||
## Steps
|
||||
|
||||
### 1. Verify Bundle Integrity
|
||||
|
||||
Before replaying, verify the bundle has not been tampered with:
|
||||
|
||||
```bash
|
||||
stella audit verify ./
|
||||
```
|
||||
|
||||
Expected output: "Bundle integrity verified"
|
||||
|
||||
### 2. Replay Verdict
|
||||
|
||||
Replay the verdict using the knowledge snapshot:
|
||||
|
||||
```bash
|
||||
{snapshot.ReplayCommand}
|
||||
```
|
||||
|
||||
This will re-evaluate the policy using the frozen inputs from the original evaluation.
|
||||
|
||||
### 3. Compare Results
|
||||
|
||||
Compare the replayed verdict with the original:
|
||||
|
||||
```bash
|
||||
stella replay diff \
|
||||
./verdict/verdict.json \
|
||||
./replay-result.json
|
||||
```
|
||||
|
||||
Expected output: "Verdicts match - deterministic verification successful"
|
||||
|
||||
## Expected Result
|
||||
|
||||
- Verdict decision should match: Check `verdict/verdict.json` for original decision
|
||||
- All gate evaluations should produce identical results
|
||||
- Evidence references should resolve correctly
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Replay produces different result
|
||||
|
||||
1. **Policy version mismatch:** Ensure the same policy version is used
|
||||
```bash
|
||||
stella policy version --show
|
||||
```
|
||||
|
||||
2. **Missing evidence:** Verify all evidence files are present
|
||||
```bash
|
||||
stella audit verify ./ --strict
|
||||
```
|
||||
|
||||
3. **Time-dependent rules:** Some policies may have time-based conditions
|
||||
|
||||
### Cannot connect to policy engine
|
||||
|
||||
Use offline mode with the bundled policy snapshot:
|
||||
|
||||
```bash
|
||||
stella replay snapshot \
|
||||
--manifest replay/knowledge-snapshot.json \
|
||||
--offline \
|
||||
--policy-snapshot policy/policy-snapshot.json
|
||||
```
|
||||

|

|

## Prerequisites
|
||||
- Stella CLI v2.5.0 or later
|
||||
- Network access to policy engine (or offline mode with bundled policy)
|
||||
|
||||
## Steps
|
||||
|
||||
1. Verify bundle integrity:
|
||||
```
|
||||
stella audit verify ./
|
||||
```
|
||||
|
||||
2. Replay verdict:
|
||||
```
|
||||
stella replay snapshot \
|
||||
--manifest ./replay/knowledge-snapshot.json \
|
||||
--output ./replay-result.json
|
||||
```
|
||||
|
||||
3. Compare results:
|
||||
```
|
||||
stella replay diff \
|
||||
./verdict/verdict.json \
|
||||
./replay-result.json
|
||||
```
|
||||
|
||||
## Expected Result
|
||||
Verdict digest should match: {digest}
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Replay produces different result
|
||||
- Ensure you're using the same Stella CLI version
|
||||
- Check that the policy snapshot matches the bundled version
|
||||
- Verify no external dependencies have changed
|
||||
|
||||
### Bundle verification fails
|
||||
- Re-download the bundle if transfer corruption is suspected
|
||||
- Check file permissions

## Verification
|
||||
|
||||
To verify bundle integrity:
|
||||
```bash
|
||||
stella audit verify ./
|
||||
```
|
||||
|
||||
To replay the verdict:
|
||||
```bash
|
||||
stella replay snapshot --manifest ./replay/knowledge-snapshot.json
|
||||
```
|
||||
|
||||
## For Auditors
|
||||
|
||||
This bundle contains everything needed to:
|
||||
1. Verify the authenticity of the verdict
|
||||
2. Review all evidence that contributed to the decision
|
||||
3. Replay the policy evaluation to confirm determinism
|
||||
4. Trace the complete decision chain
|
||||
|
||||
No additional tools or data sources are required.
