2. Collect evidence
3. Run checks
4. Score residual risk
5. PASS/FAIL

# Verification Before Completion Gate

Block false completion: require checklist, tests/evidence, and residual risk notes before any task is marked done.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Multi-Agent |
| Unlock | $8.49 USDC (x402 Base) |
| Triggers | completion gate, verify before done, definition of done agent, /verification-before-completion-gate |

## When to use
- Agents claim done too early
- Need hard DoD
- Ship gates for multi-agent

## Core workflow
1. Define DoD
2. Attach evidence
3. Execute checks
4. Human escalate if needed
5. Emit gate result

## Procedures (non-obvious)
### Hard fails
Missing primary artifact, failing critical tests, invented evidence.

### Soft fails
Incomplete docs with owner and due date may provisional-pass if policy allows.

## Edge cases
- Subjective quality tasks
- External QA lag

## Failure modes
- Rubber stamps
- Evidence not inspected

## Verification
- Gate decision logged
- Evidence paths real

## Artifact outputs
- `dod-checklist.md`
- `gate-result.json`
- `residual-risk.md`
