+# Reputation Probation Reinstatement Guard
+
+Self-contained reviewer artifact for SCIBASE issue #15, focused on safe reputation re-entry after moderation probation.
+
+This slice is intentionally narrow. It does not duplicate broad community ledgers, endorsement rings, review calibration, badge renewal/decay, leaderboard eligibility, civility checks, correction impact, peer-review recertification, workload equity, profile credit consent, or abuse detection. It evaluates whether reputation accrual can restart after a moderation outcome is already known.
+
+## What It Checks
+
+- Minimum probation windows before profile reputation deltas resume.
+- Open appeals that should block reinstatement.
+- Required remediation evidence and reviewer quorum.
+- Public-redacted reinstatement receipts instead of private moderation-note exposure.
+- Reputation deltas accidentally applied during probation.
+- Capped re-entry so badges and leaderboards do not jump immediately after reinstatement.
+
+## Local Verification
+
+```sh
+npm run check
+npm test
+npm run demo
+npm run verify-video
+```
+
+`npm run demo` writes reviewer artifacts to `reports/`:
+
+- `clean-audit.json`
+- `risky-audit.json`
+- `risky-review.md`
+- `summary.svg`
+- `manifest.json`
+- `demo.mp4`
+
+## Requirement Mapping
+
+- Community reputation: protects score, badge, and leaderboard updates during probation.
+- Transparency: emits redacted reinstatement decisions and remediation actions.
+- Fairness: requires remediation evidence and independent moderator quorum before trust re-entry.
+- Reviewer demonstration: synthetic clean/risky packets produce JSON, Markdown, SVG, and MP4 artifacts without credentials or external services.
