+# Reviewer Panel Consensus Monitor
+
+This module adds a focused Scientific Bounty System slice for third-party reviewer panel quality control. It helps sponsors and platform arbitrators decide whether a challenge submission is ready for phase advancement or reward action.
+
+It evaluates:
+
+- declared reviewer conflicts of interest
+- independent reviewer coverage and expertise tags
+- locked submission manifests and artifact hashes
+- reviewer score variance against the rubric threshold
+- missing reviewer feedback
+- missing decision explanations or response deadlines
+
+The output is an arbitration-ready packet with a deterministic digest, required actions, reviewer counts, the review phase, and a clear panel decision.
+
+## Usage
+
+```bash
+node reviewer-panel-consensus-monitor/demo.js
+```
+
+```js
+const { evaluateReviewerPanel } = require("./index.js");
+
+const result = evaluateReviewerPanel({
+  challengeTitle: "Climate Materials Prize",
+  phase: "final award review",
+  submission: {
+    id: "sub-2026-088",
+    teamId: "team-carbon",
+    artifactHashes: ["sha256:model", "sha256:dataset", "sha256:report"],
+    manifestLockedAt: "2026-05-18T16:40:00Z"
+  },
+  rubric: {
+    version: "v3.0",
+    criteria: ["scientific rigor", "reproducibility", "field impact"],
+    decisionThreshold: 82,
+    maxScoreVariance: 12
+  },
+  reviewers: [],
+  decision: {}
+});
+```
+
+## Verification
+
+```bash
+node reviewer-panel-consensus-monitor/test.js
+node reviewer-panel-consensus-monitor/demo.js
+```
+
+The tests cover a blocked panel with conflicts and missing review controls, an approved panel with independent consensus, and arbitration-ready evidence/remediation fields for every finding.
+
+## Demo
+
+Short demo artifact: `demo.gif`
+
+The demo uses synthetic data only. It does not call external services, use credentials, or move funds.
