+# Code Quality, Formatting, and Linting Runbook
+
+## Objective
+Establishes standardized code formatting, static analysis rules, and CI validation checks for **yieldladder**.
+
+Related Issue: #43 - [GF-10] [BACKEND] CI/CD Hardening (cargo test, clippy, pnpm lint, SDK build)
+
+## Standard Quality Gates
+1. **Formatting**: Automatic adherence to repository Prettier / rustfmt / Black configurations.
+2. **Static Linting**: Zero unhandled compiler warnings and zero strict lint suppressions.
+3. **Type Safety**: Full type annotations without implicit `any` escape hatches.
+
+## Runbook
+```bash
+# Verify formatting
+npm run format:check || cargo fmt --check
+
+# Execute static analysis
+npm run lint || cargo clippy -- -D warnings
+```
