# Backend Framework References

This bundle pins backend/runtime framework guidance for deterministic AI work.
Use it before browsing unless a chunk explicitly requires latest docs.

## References

- Node.js: `docs/node-reference.md`, source `https://nodejs.org/docs/latest/api/`
- TypeScript: `docs/typescript-reference.md`, source `https://www.typescriptlang.org/docs/`
- NestJS: `docs/nestjs-reference.md`, source `https://docs.nestjs.com/`
- Socket.IO: `docs/socketio-reference.md`, source `https://socket.io/docs/v4/`

## Usage

- NestJS module, service, resolver, guard, provider, and testing work must
  consult the NestJS reference and `ai/standards/nest.md`.
- Runtime, daemon, supervisor, testing, validation, and service-health logic is
  Node/TypeScript-owned by default; shell remains compatibility-only according
  to `ai/standards/shell-entrypoint-cutover.md`.
- Socket.IO remains an invalidation transport. Canonical state comes from
  Runtime/backend GraphQL snapshots and Runtime state surfaces.
