UI: render move history as a per-seat column grid + swipe-down to open
Replace the flat chronological move list with a ruled matrix aligned under the
score plaque: one column per seat, each seat's moves filling its column top to
bottom. A cell is the move's word(s) and its score, "WORD (12)", centred; the
player names and the running total are dropped (the plaque heads the column and
shows the live total). Non-play moves keep their dim parenthesised tag; the
awaited opponent's next cell shows a dim "thinking..." (never the viewer's own
turn). Thin 1px rules between columns and rows match the panel's separator.

Re-introduce a swipe-down-on-the-board gesture to open the history, gated to the
zoom-out board scrolled to its top so it never fights the zoomed board's pan or
the stage's own vertical scroll (the conflict that retired this gesture before).

Grid layout extracted to lib/history.ts (unit-tested); add game.thinking to the
EN/RU catalogs; e2e covers the gesture and the grid on Chromium and WebKit.

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.
  • backend — internal-only service that owns every domain concern and embeds the scrabble-solver engine 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.
  • 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 -f backend/Dockerfile -t scrabble-backend .   # pulls the 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.
