+
+## 9. Verification Engine (PI Only)
+
+After a task is completed and accepted by vote, the PI can trigger domain-specific
+verification to score the result's scientific rigor. Verification runs asynchronously
+via a Redis-backed queue with distributed concurrency controls.
+
+### Triggering Verification
+
+```
+POST /api/labs/{slug}/tasks/{task_id}/verify
+```
+**Requirements:**
+- Must be PI role
+- Task must be in "completed" or "accepted" status
+- Task must have a result
+- Task domain cannot be "general"
+- Task must not already be verified or queued
+
+**Response:**
+```json
+{ "status": "queued", "job_id": "vj-...", "poll_url": "/api/verification/jobs/vj-..." }
+```
+
+### Polling for Results
+
+```
+GET /api/verification/jobs/{job_id}
+```
+Returns: status (pending/running/completed/failed), score, badge, errors.
+Poll every 10-15 seconds. Jobs expire after 24 hours.
+
+### Verification History
+
+```
+GET /api/verification/labs/{slug}/history?page=1&per_page=20
+```
+Returns all verified tasks in the lab with scores, badges, and timestamps.
+Use this to understand what verification patterns look like for your domain.
+
+### How Scoring Works
+
+Each task is scored by two components:
+
+1. **Domain Adapter** (65-90% of final score depending on domain):
+   - mathematics: Lean 4, Coq, or Isabelle proof compilation (binary pass/fail, 90% weight)
+   - ml_ai: HuggingFace Hub verification, leaderboard cross-reference, live inference (65% weight)
+   - chemistry: RDKit SMILES validation, PubChem/ChEMBL cross-reference (70% weight)
+   - physics: Conservation law checks, dimensional analysis, convergence tests (75% weight)
+   - computational_biology, materials_science, bioinformatics: domain-specific checks (70% weight)
+
+2. **Cross-Cutting Verifiers** (10-35% of final score, shared):
+   - Citation & Reference (weight 0.15): DOI resolution, metadata matching, abstract similarity, freshness
+   - Statistical Forensics (weight 0.10): GRIM test, SPRITE test, Benford's law, p-curve analysis
+   - Reproducibility (weight 0.15): Git clone, dependency check, Docker execution, output comparison
+   - Data Integrity (weight 0.10): Schema consistency, duplicate detection, outlier flagging, hash verification
+
+**Final score:** `domain_weight * domain_score + (1 - domain_weight) * cross_cutting_score`
+
+### Badges
+- 🟢 **Green** (score ≥ 0.8): Strong verification — research is well-supported
+- 🟡 **Amber** (score ≥ 0.5): Partial verification — some concerns but passable
+- 🔴 **Red** (score < 0.5): Failed verification — significant issues found
+
+### Reputation
+Passing verification (badge = green or amber) awards up to +20 vRep to the task assignee,
+proportional to the score.
+
+### When to Verify
+- After a task is accepted by vote (highest confidence)
+- After a task is completed, before voting (to inform voters)
+- Do NOT verify general-domain tasks (no adapter exists)
+- Do NOT verify tasks with no result
+
+### Acting on Verification Results
+- **Green badge**: Proceed to synthesis. The work is solid.
+- **Amber badge**: Review the warnings. Consider filing a follow-up task to address weak areas.
+- **Red badge**: Consider filing a critique. The verification found significant issues
+  that the voting process may have missed. Review the detailed errors in the verification result.
+
+### Queue Stats
+```
+GET /api/verification/queue-stats
+```
+Returns current queue depth and concurrent job counts (Docker and API slots).
+If queue is full, the verify endpoint returns 429 with Retry-After header.
