distributed transactions, and distributed tracing.\n\n# Level 1: Architecture\nGoal: Build a resilient microservices architecture supporting independent service deployment,\n    cross-service communication, fault isolation, distributed transaction coordination via saga,\n    and full observability through distributed tracing.\n\nConstraint: No service may directly reference another service's internal data store.\nConstraint: All inter-service communication must traverse the API gateway.\nConstraint: Each service must be independently deployable and scalable.\nConstraint: Latency for synchronous calls must remain below 200ms p99.\nConstraint: Saga transactions must complete within 30 seconds or compensate.\n\nRisk: Service discovery failure leaves orphaned instances\nRecovery: Fallback to static registry with heartbeat-based health checks and manual override\n\nRisk: Circuit breaker cascade causes system-wide outage\nRecovery: Bulkhead isolation per service with independent breaker pools and graceful degradation\n\nRisk: Saga participant crash mid-transaction leaves partial state\nRecovery: Saga orchestrator retries with exponential backoff; compensating transactions for unrecoverable failures\n\nRisk: API gateway becomes single point of failure\nRecovery: Deploy gateway replicas across availability zones with leader election and failover routing\n\nRisk: Distributed trace context lost across async boundaries\nRecovery: Inject trace context into message headers; background reconciler repairs broken traces\n\nRisk: Network partition causes split-brain service registry\nRecovery: Quorum-based registration with majority-wins consensus and stale-entry eviction\n\nLayer: Infrastructure\n    SubLayer: ServiceDiscovery\n    SubLayer: APIGateway\n    SubLayer:

deployed service count\nValidation: Circuit breaker open duration must not exceed 60 seconds\nValidation: Saga transaction must have a defined compensating action for every step\nValidation:

input validation, and CSRF protection.\n\n# Level 1: Architecture\nGoal: Build a production MVC web application framework supporting clean separation of concerns,\n    declarative routing with parameter extraction, middleware pipeline for cross-cutting logic,\n    secure session management, and view template rendering with layout inheritance.\n\nConstraint: Controllers must not contain business logic; delegate to service layer.\nConstraint: Views must not execute arbitrary code; only template expressions permitted.\nConstraint: All user input must be validated before reaching controller logic.\nConstraint: Session data must be stored server-side; client holds only a signed session ID.\nConstraint: Each route must declare its HTTP method, path pattern, and required middleware.\n\nRisk: Session hijacking via stolen session cookie\nRecovery: Regenerate session ID on privilege elevation; bind session to IP and user-agent fingerprint\n\nRisk: CSRF token bypass on state-changing requests\nRecovery: Double-submit cookie pattern with SameSite=Strict attribute and token rotation per request\n\nRisk: Template injection through unsanitized user input\nRecovery: Auto-escape all template expressions by default; explicit unescape requires safe annotation\n\nRisk: Route collision causing request misrouting\nRecovery: Detect route conflicts at startup; first-registered wins with warning for duplicates\n\nRisk: Middleware ordering causes authentication bypass\nRecovery: Enforce middleware dependency graph; validate ordering at route registration time\n\nRisk: Memory leak from unbounded session store\nRecovery: Set session TTL of 30 minutes; background sweeper evicts expired sessions every 60 seconds\n\nLayer: Presentation\n    SubLayer:

Request body must conform to content-type schema before controller dispatch\nValidation: Session ID must be cryptographically signed and unexpired\nValidation: CSRF token must match server-side stored token for the session\nValidation: Response content-type must match route declaration\nValidation: Middleware pipeline must not skip authentication for protected routes\n\n# Level 2: Entities\nEntity

of work for transactions, multi-level caching, and connection management.\n\n# Level 1: Architecture\nGoal: Build a repository pattern data access layer that abstracts persistence details,\n    supports specification-based composable queries, manages transactions via unit of work,\n    provides multi-level caching, and ensures data consistency across operations.\n\nConstraint: Domain layer must never reference infrastructure persistence directly.\nConstraint: All queries must be expressed as specification objects, not raw query strings.\nConstraint: Each unit of work scope must correspond to exactly one transaction.\nConstraint: Cache invalidation must occur within the same transaction as the write.\nConstraint: Repository interfaces must be defined in the domain layer; implementations in infrastructure.\n\nRisk: Cache returns stale data after write\nRecovery: Invalidate cache entries within write transaction; use write-through for critical entities\n\nRisk: Unit of work rollback leaves cache in inconsistent state\nRecovery: Enroll cache in transaction participation; rollback cache operations on transaction abort\n\nRisk: Specification composition creates N+1 query problem\nRecovery: Detect eager-load annotations; auto-join related entities via specification visitor\n\nRisk: Connection pool exhaustion under high concurrency\nRecovery: Queue requests with timeout; scale pool dynamically based on wait-time metrics\n\nRisk: Optimistic concurrency conflict on high-contention entities\nRecovery: Retry with exponential backoff up to 3 times; escalate to pessimistic lock if threshold exceeded\n\nRisk: Repository abstraction leaks persistence details through error types\nRecovery: Translate all infrastructure exceptions to domain-specific error types at repository boundary\n\nLayer: Domain\n    SubLayer: RepositoryInterface\n    SubLayer: Specification\n    SubLayer: AggregateRoot\nLayer: Application\n    SubLayer: UnitOfWork\n    SubLayer: TransactionManager\n    SubLayer: SpecificationComposer\nLayer: Infrastructure\n    SubLayer: RepositoryImplementation\n    SubLayer: CacheLayer\n    SubLayer: ConnectionPool\n\nValidation: Repository method must accept and return domain types only\nValidation: Specification must be serializable for cache key generation\nValidation: Unit of work must not span multiple database connections\nValidation: Cache TTL must be less than or equal to source data freshness requirement\nValidation: Connection pool size must match concurrent transaction limit\nValidation: All repository write operations must participate in active unit of work\n\n# Level 2: Entities\nEntity Repository\n    repositoryId: string\n    aggregateType: string\n    connectionString: string\n    cacheEnabled:

strategy composition, and fallback mechanisms.\n\n# Level 1: Architecture\nGoal: Build a strategy pattern engine that enables runtime algorithm selection and switching,\n    supports automated benchmarking for strategy comparison, allows strategy composition\n    for complex operations, and provides graceful fallback when strategies fail.\n\nConstraint: Each strategy must implement a common interface with identical input and output contracts.\nConstraint: Strategy selection must be deterministic given the same context and input.\nConstraint: Benchmarking must not affect production strategy execution latency.\nConstraint: Strategy switching must be atomic with no in-flight operations using the old strategy.\nConstraint: Composite strategies must maintain the execution order declared in composition.\n\nRisk: Strategy switch during active execution causes inconsistent results\nRecovery: Complete in-flight operations with old strategy; apply new strategy to subsequent requests only\n\nRisk: Benchmark sample too small produces unreliable comparison\nRecovery: Require minimum sample size of 1000 executions; extend benchmark until confidence interval narrows\n\nRisk: Composite strategy partial failure leaves partial output\nRecovery: Apply compensating actions for completed steps; fall back to simpler non-composite strategy\n\nRisk: Memory leak from accumulated benchmark data\nRecovery: Sliding window of 1 hour for benchmark samples; compress older data into summary statistics\n\nRisk: Strategy selection oscillates between equivalent strategies causing instability\nRecovery: Hysteresis threshold requiring 10% improvement over incumbent before switching\n\nRisk: Custom strategy injection compromises system integrity\nRecovery: Sandbox custom strategies with resource limits; validate against strategy contract at registration\n\nLayer: Core\n    SubLayer: StrategyRegistry\n    SubLayer: StrategySelector\n    SubLayer:

logging, authentication, rate limiting, caching, and compression.\n\n# Level 1: Architecture\nGoal: Build a decorator pattern pipeline that composes middleware chains for request processing,\n    applies request and response filters for cross-cutting concerns, supports ordering and\n    conditional activation of decorators, and enables transparent addition of behaviors without\n    modifying core business logic.\n\nConstraint: Each decorator must have a single responsibility and not mix concerns.\nConstraint: Decorator order must be explicitly declared; implicit ordering is forbidden.\nConstraint: A decorator must not swallow exceptions from inner handlers without re-raising or wrapping.\nConstraint: Pipeline must support both request and response decoration phases.\nConstraint: Each decorator must be independently testable without the full pipeline.\n\nRisk: Decorator order sensitivity causes subtle bugs\nRecovery: Document order dependencies; validate ordering constraints at pipeline construction time\n\nRisk: Exception in decorator leaves pipeline in partial state\nRecovery: Execute response decorators in reverse order on error path; ensure cleanup decorators run always\n\nRisk: Performance overhead from deep decorator nesting\nRecovery: Profile pipeline latency per decorator; collapse trivial decorators; add short-circuit option\n\nRisk: Decorator side effects leak between requests\nRecovery: Enforce per-request decorator state isolation; detect shared mutable state at registration\n\nRisk: Missing decorator causes silent feature gap\nRecovery: Declare required decorators per route; fail at startup if required decorator is missing\n\nRisk: Decorator configuration drift across environments\nRecovery: Version pipeline configurations; validate deployed configuration matches declared schema\n\nLayer: Pipeline\n    SubLayer: PipelineBuilder\n    SubLayer: PipelineExecutor\n    SubLayer: DecoratorChain\nLayer:

 SubLayer: RequestHandler\n    SubLayer: ResponseProcessor\n    SubLayer: ErrorHandler\n\nValidation: Each decorator must implement before and after hooks\nValidation: Pipeline must contain at least one terminal handler\nValidation: Decorator ordering must satisfy declared dependency constraints\nValidation: No decorator may modify the request object in place; must return new instance\nValidation: Pipeline execution time must not exceed configured maximum\nValidation: Error handler decorator must be present in every pipeline\n\n# Level 2: Entities\nEntity Pipeline\n

Plugin dependency cycles must be detected and rejected at installation time.\n\nRisk: Malicious plugin escapes sandbox and accesses host resources\nRecovery: Kill plugin process immediately; audit all accessed resources; blacklist plugin signature\n\nRisk: Plugin hot reload leaves orphaned event listeners or timers\nRecovery: Track all registered callbacks per plugin; revoke and clean up on unload before activating new version\n\nRisk: API version mismatch causes runtime errors in dependent plugins\nRecovery: Validate version compatibility graph before loading; isolate incompatible plugins to separate sandbox\n\nRisk: Plugin memory leak degrades host performance\nRecovery: Enforce per-plugin memory quota; automatically unload plugin exceeding limit with notification\n\nRisk: Circular
