-# Contributing to the Nexus
+# Branch Protection & Code Review Policy
 
-**Every PR: net ≤ 10 added lines.** Not a guideline — a hard limit.
-Add 40, remove 30. Can't remove? You're homebrewing. Import instead.
+**Effective immediately for all repositories**
 
-## Why
+## Core Requirements
+1. **All changes must use Pull Requests**
+   - Direct pushes to `main` are prohibited
+2. **Minimum Review Requirements**
+   - 1+ approvals required to merge
+   - @perplexity must be notified for review
+   - Original author cannot approve their own PR
 
-Import over invent. Plug in the research. No builder trap.
-Removal is a first-class contribution. Baseline: 4,462 lines (2026-03-25). Goes down.
+3. **CI/CD Requirements**
+   - All CI pipelines must pass before merge
+   - No merging of failing builds
+   - No force-pushing to protected branches
 
-## PR Checklist
+## Repository-Specific Rules
 
-1. **Net diff ≤ 10** (`+12 -8 = net +4 ✅` / `+200 -0 = net +200 ❌`)
-2. **Manual test plan** — specific steps, not "it works"
-3. **Automated test output** — paste it, or write a test (counts toward your 10)
