+# Branch Protection Policy for Timmy Foundation
+
+## Enforced Rules for All Repositories
+
+All repositories must enforce these rules on the `main` branch:
+
+| Rule | Status | Rationale |
+|------|--------|-----------|
+| Require PR for merge | ✅ Enabled | Prevent direct commits |
+| Required approvals | 1+ | Minimum review threshold |
+| Dismiss stale approvals | ✅ Enabled | Re-review after new commits |
+| Require CI to pass | ⚠ Conditional | Only where CI exists |
+| Block force push | ✅ Enabled | Protect commit history |
+| Block branch deletion | ✅ Enabled | Prevent accidental deletion |
+
+## Default Reviewer Assignments
+
+- **All repositories**: @perplexity (QA gate)
+- **hermes-agent**: @Timmy (owner gate)
+- **Specialized areas**: Repo-specific owners for domain expertise
+
+## CI Enforcement Status
+
+| Repository | CI Status | Notes |
+|------------|-----------|-------|
+| hermes-agent | ✅ Active | Full CI enforcement |
+| the-nexus | ⚠ Pending | CI runner dead (#915) |
+| timmy-home | ❌ Disabled | No CI configured |
+| timmy-config | ❌ Disabled | Limited CI |
+
