+# Rubber-Stamping Prevention
+
+## What is Rubber-Stamping?
+
+Rubber-stamping is approving a PR without actually reviewing the code. This was observed in PR #359 which received 3 APPROVED reviews despite having zero changes.
+
+## Why It's Bad
+
+1. Wastes reviewer time
+2. Creates false sense of review quality
+3. Allows zombie PRs to appear reviewed
+
+## Prevention Measures
+
+### 1. CI Check (`.gitea/workflows/check-pr-changes.yml`)
+
+Automated check that runs on every PR:
+- Detects PRs with no changes (0 additions, 0 deletions, 0 files changed)
+- Blocks merge if PR is a zombie
+- Provides clear error messages
+
+### 2. PR Template
+
+Enhanced reviewer checklist:
+- Verify PR has actual changes
+- Changes match description
+- Code quality review
+- Tests are adequate
+- Documentation is updated
+
+### 3. Zombie PR Detection
+
+```bash
+# Scan all repos
+python bin/check_zombie_prs.py
+
+# Scan specific repos
+python bin/check_zombie_prs.py --repos the-nexus timmy-home
+
+# Generate report
+python bin/check_zombie_prs.py --report
+```
+
+## Testing
+
+```bash
+# Create a test PR with no changes
+git checkout -b test/zombie-pr
+git commit --allow-empty -m "test: empty commit"
+git push origin test/zombie-pr
+# Create PR — CI should fail
+```
