// Implement or refactor backend HTTP routing and controllers using a layered pattern (routes delegate, controllers validate and call services).
Evidence-driven debugging loop with mandatory instrumentation + fix approvals, run_id-tagged logs, default 3-pass verification for flaky issues, and guaranteed cleanup of debug-only instrumentation.
Design or review a layered backend architecture (routes, controllers, services, repositories) for HTTP APIs and microservices.
Apply cross-cutting backend service patterns across routing, services, repositories, validation, configuration, errors, and tests.
Manage backend configuration safely with typed, validated settings and clear separation between defaults and secrets.
Apply safe and maintainable backend database patterns (transactions, pagination, soft deletes, query optimization, data consistency).
Build backend service and repository layers to isolate business logic from persistence and improve testability.
