+# Resilience and Configuration
+
+External dependencies will fail. Configuration must be externalized.
+
+## Resilience
+
+- Every external call must have a **timeout**. No indefinite waits.
+- **Critical** deps: fail visibly, return error. **Non-critical**: log, serve cached/default, degrade gracefully.
+- **Circuit breakers** for repeatedly failing deps. Exponential backoff.
+- **Retries**: bounded, exponential backoff + jitter, idempotent operations only. Non-idempotent mutations require an idempotency key.
+- Make degradation **visible**: log it, expose in health check.
+- **Health checks**: verify actual dependency connectivity, not just "process running."
+
+## Configuration
+
+- Externalize all config. Document every knob: purpose, default, valid range, environments.
+- Sensible defaults — runnable with zero config for local dev.
+- Maintain `.env.example` with all variables and descriptions.
+- Validate required config at startup — fail fast. Log effective config (secrets masked).
+
+## Graceful Shutdown
+
+- Stop accepting new requests, drain in-flight work, release resources (12-Factor IX).
