+# Peer Review Civility And Evidence Gate
+
+This module is a focused slice for issue #15, Community & User Reputation System. It protects the review and comment layer before content is published to project timelines or allowed to affect researcher reputation.
+
+It is intentionally not another broad reputation ledger. The gate evaluates structured peer reviews and inline comments for:
+
+- harassment or personal attacks
+- protected or personal identity disclosures
+- anonymous, blind, or double-blind reviewer identity leaks
+- low structured scores that lack evidence anchors
+- missing inline artifact anchors
+- repeated comments that should be collapsed before reputation impact
+
+The output is a deterministic moderation packet with blockers, warnings, redactions, withheld item IDs, and a release recommendation.
+
+## Run
+
+```bash
+node review-civility-evidence-gate/test.js
+node review-civility-evidence-gate/demo.js
+```
+
+The demo writes:
+
+- `reports/civility-evidence-packet.json`
+- `reports/civility-evidence-report.md`
+- `reports/summary.svg`
+- `reports/summary.png`
+- `reports/demo.mp4`
+
+## Design Notes
+
+- Dependency-free Node.js implementation for the core logic.
+- Synthetic data only. No credentials or external services.
+- Evidence anchors support DOI, URLs, figure/table references, dataset IDs, commits, notebook cells, lines, protocols, sections, and artifacts.
+- Reputation impact is withheld while blockers are present.

+# Acceptance Notes
+
+## What To Review
+
+- `index.js` implements the peer-review civility and evidence gate.
+- `sample-data.js` includes synthetic unsafe and clean packets.
+- `test.js` validates blocker, redaction, anonymous leak, clean-pass, and report rendering behavior.
+- `demo.js` generates the reviewer packet and visual demo artifact.
+
+## Verification
+
+```bash
+node review-civility-evidence-gate/test.js
+node review-civility-evidence-gate/demo.js
+node --check review-civility-evidence-gate/index.js
+node --check review-civility-evidence-gate/sample-data.js
+node --check review-civility-evidence-gate/test.js
+node --check review-civility-evidence-gate/demo.js
+git diff --check
+ffprobe -v error -select_streams v:0 -show_entries stream=codec_name,width,height,duration -of default=noprint_wrappers=1 review-civility-evidence-gate/reports/demo.mp4
+```
+
+## Expected Demo Result
+
+The sample packet should return `hold_review_publication` with blockers for harassment, unsupported low-score claims, anonymous reviewer identity leakage, and protected identity disclosure. The clean packet should return `community_ready`.
