+## Before every push — MANDATORY
+
+Run all three steps for every affected service (`admin-compliance/`, `developer-portal/`) before pushing. CI runs the same checks and will fail if you skip this.
+
+```bash
+cd admin-compliance   # or developer-portal
+
+# 1. Build — catches type errors and module resolution failures
+npm run build
+
+# 2. Lint
+npx tsc --noEmit
+npx eslint . --max-warnings 0
+
+# 3. Tests
+npm test
+```
+
+All three must exit 0. Do not push if any step fails.

 ## Performance
 
 - Use `next/dynamic` for heavy client-only components.
