@opendj/backend

Hono-based route tree, services, and an explicit dependency graph (deps.ts) usable from both Node and Cloudflare Workers.

Contents (planned — see docs/agent-brief.md §"Backend package directory structure"):

• app.ts — Hono app factory
• deps.ts — explicit dependency graph (no decorator DI)
• auth/ — AuthService, ClaimsService, PasswordService, auth provider registry, middleware
• abuse/ — abuse signal capture, risk scoring, rate limiting, middleware
• providers/streaming/ — StreamingRouter, providerRegistry, Spotify / Soundtrack / Apple Music adapters
• services/ — GuestIdentityService, SlotManager, QueueService, SessionService
• routes/ — auth, sessions, queue, guest, moderation, provider, lyrics, realtime upgrade, health

Routes versioned under /api/v1. Future breaking changes go to /api/v2 rather than mutating in place.
