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`](../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)*
|
|
|
|
## Documentation (sources of truth)
|
|
|
|
- [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) — global architecture, transport,
|
|
security, cross-service contracts.
|
|
- [`docs/FUNCTIONAL.md`](docs/FUNCTIONAL.md) (+ [`_ru`](docs/FUNCTIONAL_ru.md)) —
|
|
per-domain user stories.
|
|
- [`docs/TESTING.md`](docs/TESTING.md) — test layers and the per-stage CI gate.
|
|
- [`PLAN.md`](PLAN.md) — the staged implementation plan and stage tracker.
|
|
- [`CLAUDE.md`](CLAUDE.md) — project guide and the mandatory per-stage workflow.

## Build & test
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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`](backend/README.md).
