Effect-First Design +**Decision**: All business logic as Effects, Next.js only at boundary. + +**Rationale**: +- Type-safe error handling +- Composable, testable logic +- Resource management with acquire/release +- Dependency injection via Context + +**Trade-off**: Wrapper required for OpenTelemetry SDK (no direct Effect binding available). + +### 2. Thin OTLP Wrapper +**Decision**: Wrap `@opentelemetry/sdk-node` with Effect Layer. + +**Implementation**: +- `Effect.acquireRelease` for SDK lifecycle +- Effect helpers for span operations +- Documented in code comments + +**Rationale**: No official Effect-to-OTLP binding exists; this provides proper resource management while maintaining Effect semantics. + +### 3. In-Memory Pattern Cache +**Decision**: Load patterns.json into Effect Ref at cold-start. + +**Rationale**: +- Fast reads (no disk I/O per request) +- Simple for MVP +- Can be replaced with database later + +**Limitation**: Requires server restart to reload patterns. + +### 4.
