Stage 6: gateway edge (Connect/FlatBuffers over h2c, platform/email/guest auth, sessions, rate-limit, admin passthrough, live push bridge)
New public ingress and the first network edge. Framework + a vertical slice of
operations end-to-end; remaining ops reuse the same transcode pattern in Stage 7.

Contracts (new module scrabble/pkg):
- push.proto (backend->gateway gRPC server-stream) + scrabble.fbs (FlatBuffers
  edge payloads), committed generated Go; buf/flatc Makefiles (dev-time codegen).

Backend:
- REST handlers on the /api/v1 groups: internal session endpoints
  (telegram/guest/email login -> mint, resolve, revoke) and the user slice
  (profile, submit_play, state, lobby enqueue/poll, chat).
- internal/notify in-process Publisher hub + internal/pushgrpc gRPC server
  (BACKEND_GRPC_ADDR) streaming your_turn/opponent_moved/chat/nudge/match_found;
  emission in game.commit, social, matchmaker.
- migration 00005 accounts.is_guest; guests are durable rows excluded from stats;
  ProvisionGuest; email-as-login (RequestLoginCode/LoginWithCode).

Gateway (new module scrabble/gateway):
- Connect Gateway service over h2c (Execute + Subscribe), FlatBuffers<->JSON
  transcode registry, Telegram initData HMAC validator (seam), session cache,
  token-bucket rate limiter (3 classes), push fan-out hub, backend REST + push
  gRPC client, admin Basic-Auth reverse proxy.

go.work: use ./pkg, ./gateway + replace scrabble/pkg. CI: gateway/**, pkg/**
path filters; unit build/vet/test span all three modules. Docs (PLAN,
ARCHITECTURE, FUNCTIONAL+ru, TESTING, READMEs) updated; gateway/pkg unit tests +
guest/email-login integration tests.

scrabble-game

Multiplatform Scrabble game. Players arrive from a platform (Telegram first; later VK/MAX/iOS/Android) or from standalone web (email / guest). The game supports English Scrabble, Russian Scrabble and Эрудит.

Components

  • gateway — the only public ingress: anti-abuse, platform authentication (resolves the player and injects X-User-ID), routing to backend, and an admin surface behind Basic Auth. (added in a later stage)
  • backend — internal-only service that owns every domain concern and embeds the scrabble-solver engine library in-process.
  • ui — pure-HTML5 client (plain Svelte + Vite), embeddable in platform webviews and packageable to native via Capacitor. (added in a later stage)
  • platform/* — per-platform side-services (e.g. the Telegram bot). (added in a later stage)

Build & test

go build ./backend/... ./pkg/... ./gateway/...  # per module (the workspace spans several)
go vet ./backend/... ./pkg/... ./gateway/...
gofmt -l .                                       # must print nothing
go test -count=1 ./backend/... ./pkg/... ./gateway/...   # unit tests
go test -tags=integration -count=1 -p=1 ./backend/...    # + Postgres (needs Docker)

The integration-tagged tests start a throwaway postgres:17-alpine container via testcontainers-go and require a reachable Docker daemon; they live in the backend module. The wire contracts in pkg and the Connect edge in gateway have committed generated code (regenerate dev-time with make -C pkg gen / make -C gateway gen).

Run the backend locally

The backend now owns persistence, so it needs Postgres and applies its embedded migrations at startup:

docker run -d --name scrabble-pg -e POSTGRES_PASSWORD=dev -p 5432:5432 postgres:17-alpine
BACKEND_POSTGRES_DSN='postgres://postgres:dev@localhost:5432/postgres?search_path=backend&sslmode=disable' \
  go run ./backend/cmd/backend     # HTTP API + probes on :8080, push gRPC on :9090

Run the gateway locally

The gateway is the public edge; point it at a running backend:

GATEWAY_BACKEND_HTTP_URL=http://localhost:8080 \
GATEWAY_BACKEND_GRPC_ADDR=localhost:9090 \
  go run ./gateway/cmd/gateway     # Connect/h2c edge on :8081

Key environment: BACKEND_HTTP_ADDR (default :8080), BACKEND_LOG_LEVEL (debug|info|warn|error, default info), BACKEND_POSTGRES_DSN (required). The full configuration surface and the go-jet regeneration step live in backend/README.md.
