When a guest links an identity (email/TG/VK) that already belongs to a durable account, the guest-primary rule already made the durable account the survivor and switched the session — but the client still showed an irreversible 'merge two accounts?' confirmation, which is nonsense from the user's side (they are simply signing into their account). The confirm step now merges inline for a GUEST initiator and returns the completed merge (the switched token); a durable initiator still gets the explicit confirmation (consolidating two real accounts is consequential). The active-game guard still refuses, surfaced as the clear error.merge_active_game_conflict message rather than swallowed. Also fixes the merged-away device-local games: their human/host seat was recorded under the retired account id, so after the switch the lobby and game header could not identify 'me' and showed every seat as an opponent (the game still played — turn logic is seat-index based). applyLinkResult now re-points local game seats from the retired id to the survivor (repointLocalGameSeats).

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 injectsX-User-ID), routing tobackend, and an admin surface behind Basic Auth.backend— internal-only service that owns every domain concern and embeds thescrabble-solverengine library in-process.ui— pure-HTML5 client (plain Svelte 5 + TypeScript + Vite) over Connect-RPC- FlatBuffers, embeddable in platform webviews and packageable to native via
Capacitor. See
ui/README.md.
- FlatBuffers, embeddable in platform webviews and packageable to native via
Capacitor. See
platform/*— per-platform side-services (e.g. the Telegram bot).

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.
Run the UI locally
cd ui && pnpm install
pnpm start # mock mode: lobby -> game with no backend, on http://localhost:5173
pnpm dev # against a running gateway (Vite proxies the RPC path to :8081)
pnpm check (type-check), pnpm test:unit (Vitest), pnpm test:e2e (Playwright
smoke vs the mock), pnpm build (static bundle). Details — including the committed
edge codegen (pnpm codegen) — are in ui/README.md.
Deploy (deploy/)
The full contour is deploy/docker-compose.yml:
backend + gateway (with the UI embedded via go:embed, baked in by its node
build stage) + Postgres + the Telegram connector (with a VPN sidecar) + an
observability stack (OTel Collector → Prometheus + Tempo → Grafana) + a front
caddy that owns a single /_gm Basic-Auth (admin console + Grafana). The Go
services build from multi-stage distroless */Dockerfile.
docker build --build-arg DICT_VERSION=v1.3.0 -f backend/Dockerfile -t scrabble-backend . # DICT_VERSION required; pulls that DAWG release artifact
docker build -f gateway/Dockerfile -t scrabble-gateway . # node stage builds + embeds the UI
docker compose -f deploy/docker-compose.yml config # validate (needs the TEST_/PROD_ env)
CI auto-deploys the test contour on a PR into — or push to — development
(.gitea/workflows/ci.yaml); the prod contour is a manual deploy after
development → master. Env reference: deploy/.env.example;
the topology and the two-contour model are in
docs/ARCHITECTURE.md §13.
