NestJS (6 services): implement @RequirePermission decorator with SetMetadata+Reflector, register APP_GUARD globally, fix as assertions to type guards, add explicit return types, fix import type for express, fix /metrics implicit any, replace native Error with ApplicationError, remove typeorm remnants, register LifecycleService. teacher-bff: add logger, ApplicationError, GlobalErrorFilter, forward real userId to downstream, log downstream failures, migrate health controller to shared/health. Go (2 services): interface to any, doc comments, CORS dev whitelist, JWT secret fail-fast, push-gateway internal API auth, metrics and readyz endpoints, remove dead code. Python (2 services): lifespan return type, dev_mode to bool, data-ana APIRouter, ai POST body model, ClickHouse async wrapping.
