API Response Standardization +**Decision:** All APIs return `{ success, data/error, timestamp, path }` +**Benefit:** Client-side error handling is uniform across all 100+ endpoints +**Implementation:** `apiResponse()` and `apiError()` utilities handle this + +### 2. Middleware-Based Architecture +**Decision:** Composable middleware for auth, audit, rate-limiting +**Benefit:** Eliminates 100+ lines of repetitive route logic +**Pattern:** Stack middleware composably: `withAuth(withAudit(withRateLimit(...)))` + +### 3. Unified Data Fetching Hook +**Decision:** Replace 71 manual fetch implementations with `useApi()` hook +**Benefit:** Automatic caching, retry logic, error handling, loading states +**Benefit:** Single place to manage API changes + +### 4. Business Logic Separation +**Decision:** Move logic out of components into utils (signage-utils, exam-utils, grading-engine) +**Benefit:** Testable, reusable, framework-agnostic +**Example:** `computeSecurityRisk()` can be tested without React + +### 5.
