New scrabble/loadtest module (the pre-release stress harness): seeds 1000 guest + 10000 durable accounts with pre-created sessions directly in Postgres (token hash matches backend/internal/session), drives virtual players through the edge protocol (real 2-4p games assembled via invitations, mid-ranked legal moves generated locally by the embedded scrabble-solver — the edge carries no board, so the client replays history), plus nudge/chat/check-word/draft/profile/stats and a gateway-hammer that verifies the rate limiter. Prints a trip-report summary (per-op latency percentiles, result codes, live-event tally). Go unit tests cover the pure pieces; the DAWG-backed move test runs under BACKEND_DICT_DIR. Contour: add cAdvisor + postgres_exporter + a 'Scrabble - Resources' Grafana dashboard and the two Prometheus scrape jobs, for the R2/R7 stress-run resource baseline. CI: gate ./loadtest/... (path filter + vet/build/test). Docs: TESTING, ARCHITECTURE, project CLAUDE repo layout.

# scrabble-game — project guide
|
||
|
||
Multiplatform Scrabble game. Read this first every session. The owner drives the
|
||
project **one stage per session** (tariff constraint), so the repository — not
|
||
conversation memory — is the source of continuity. Keep it that way.
|
||
|
||
## Sources of truth (read before changing behaviour)
|
||
|
||
- [`PLAN.md`](PLAN.md) — staged plan + **stage tracker** + per-stage *open
|
||
details to interview*.
|
||
- [`PRERELEASE.md`](PRERELEASE.md) — pre-release hardening tracker (phases R1–R7
|
||
before Stage 18); same per-phase *interview + bake-back* discipline as `PLAN.md`.
|
||
- [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) — architecture, transport,
|
||
security, the decision record. Always describes current state.
|
||
- [`docs/FUNCTIONAL.md`](docs/FUNCTIONAL.md) (+ [`_ru`](docs/FUNCTIONAL_ru.md)
|
||
mirror) — per-domain user stories. English authoritative.
|
||
- [`docs/TESTING.md`](docs/TESTING.md) — test layers + the per-stage CI gate.
|
||
- [`docs/UI_DESIGN.md`](docs/UI_DESIGN.md) — the `ui` visual/interaction design system.
|
||
|
||
## Mandatory per-stage workflow
|
||
|
||
**Start of a stage**
|
||
1. Read `PLAN.md` (the stage's scope + *open details*) and the relevant `docs/`.
|
||
2. Analyse what the stage actually requires against the current code.
|
||
3. **Interview the owner** on every open detail and any fork not already fixed
|
||
in the plan — do not silently pick borderline decisions. Offer options with
|
||
brief pros/cons.
|
||
4. Only then implement, strictly within the stage's scope.
|
||
|
||
**End of a stage**
|
||
1. Bake every new agreement back into `PLAN.md`, `docs/ARCHITECTURE.md`,
|
||
`docs/FUNCTIONAL.md` (+ `_ru`), the affected service `README`, and Go Doc
|
||
comments — in the **same** PR. Correct earlier stages' docs/code if a new
|
||
decision changes them.
|
||
2. Update the stage tracker; add a line under *Refinements logged during
|
||
implementation* for any plan deviation.
|
||
3. Get CI green, then mark the stage done.
|
||
|
||
(The `stage-implementation` skill encodes this same loop and can be invoked.)
|
||
|
||
## Conventions
|
||
|
||
- All code, comments, identifiers, commits, docs, filenames in **English**.
|
||
- Chat with the owner follows the user-level `~/.claude/CLAUDE.md` (Russian,
|
||
the agreed persona and translation rules).
|
||
- Mirror every point edit of `docs/FUNCTIONAL.md` into `docs/FUNCTIONAL_ru.md`
|
||
in the same patch (translate only the touched paragraphs).
|
||
- Prefer compact code; do not add deps, seams or knobs until a stage needs them.
|
||
Reuse before adding. Document added packages/types/funcs with Go Doc comments.
|
||
- Update or add tests for every functional change.
|
||
|
||
## Branching & CI
|
||
|
||
- **Two long-lived branches** (Stage 16 onward): **`development`** is the
|
||
integration branch; **`master`** is the production trunk. Cut `feature/*`
|
||
branches **from `development`** and PR them back into it. (Stages 0–15 used
|
||
`master` as the trunk with `feature/* → master`; the genesis Stage 0 commit is
|
||
on `master` by necessity.)
|
||
- A commit to a `feature/*` branch triggers **nothing**. The single workflow
|
||
`.gitea/workflows/ci.yaml` runs the full suite (`unit` + `integration` + `ui`)
|
||
on a PR into `development` or `master`, and the gated **`deploy`** job auto-rolls
|
||
the **test contour** on a PR into — or a push to — `development`
|
||
(`docker compose up -d --build` on the runner host + a `GET /` probe). A PR into
|
||
`master` is test-only.
|
||
- Merge `development → master` only when CI is green; the **prod** deploy is then a
|
||
**manual** workflow (Stage 18), never automatic. Secrets/variables are prefixed
|
||
`TEST_` / `PROD_` per contour (Gitea 1.26 has no deployment environments).
|
||
- After any push, watch the run to green before declaring a stage done — use the
|
||
ready-made watcher, never an inline poll loop:
|
||
`python3 ~/.claude/bin/gitea-ci-watch.py` (background). It reads `$GITEA_URL`
|
||
/ `$GITEA_TOKEN`; `gitea.iliadenisov.ru` is allow-listed in
|
||
`.claude/settings.json`. Remote: `origin git@gitea.iliadenisov.ru:developer/scrabble-game.git`.
|
||
|
||
## Stack
|
||
|
||
Go 1.26.3, `go.work` monorepo, module paths `scrabble/<name>`. Dependencies are
|
||
added **when first used** (incremental): backend uses `gin` + `zap` +
|
||
`pgx`/`go-jet`/`goose`/OTel (added in Stage 1). Client↔gateway is Connect-RPC +
|
||
FlatBuffers (h2c); gateway↔backend is REST/JSON + `X-User-ID` plus a gRPC
|
||
server-stream for live events. UI is pure HTML5/CSS on plain Svelte + Vite,
|
||
packaged to native with Capacitor. Likely no Redis.
|
||
|
||
## Reused engine: `../scrabble-solver` (module `scrabble-solver`, Go 1.26.3)
|
||
|
||
Embedded **in-process as a library** — there is no per-game container. Public
|
||
API to reuse (do not reimplement):
|
||
|
||
- `scrabble.NewSolver(rs, finder)` → `GenerateMoves(b, r, mode)` (ranked,
|
||
highest score first), `ValidatePlay(b, dir, tiles)`, `ScorePlay(...)`;
|
||
`scrabble.Apply(b, m)`; types `Move/Word/Placement/Direction/Mode`
|
||
(`scrabble-solver/scrabble/{solver,move,apply}.go`).
|
||
- `rules.English() / RussianScrabble() / Erudit()`
|
||
(`scrabble-solver/rules/rules.go`).
|
||
- `board.New / Parse / Clone / Transpose`; `rack.New / Add / Remove / Clone`;
|
||
`selfplay.NewBag / Draw / Len` (bag pattern).
|
||
- Load committed dictionaries with `dawg.Load(path)` from
|
||
`github.com/iliadenisov/dafsa`:
|
||
`scrabble-solver/dawg/{en_sowpods,ru_scrabble,ru_erudit}.dawg`.
|
||
|
||
Constraints:
|
||
- Words/tiles are **alphabet-index bytes**, meaningful only with the matching
|
||
`rules.Ruleset` (`Alphabet.Decode`); blank flag carried separately. **Decode
|
||
to real characters before persisting history** (history must be
|
||
dictionary-independent — see `docs/ARCHITECTURE.md` §9.1).
|
||
- The solver's `internal/*` is NOT importable from this sibling module.
|
||
- **GCG is test-only** in the solver (no public writer) — we ship our own.
|
||
- Wiring: add `replace scrabble-solver => ../scrabble-solver` to `go.work` in
|
||
**Stage 2** (when `internal/engine` first imports it), and make CI check out
|
||
the solver sibling (`https://gitea.iliadenisov.ru/.../scrabble-solver.git`).
|
||
It uses published `github.com/iliadenisov/{alphabet,dafsa}` (no local replace).

## Build & test
|
||
|
||
```sh
|
||
go build ./backend/... # per module ('./...' from the root won't span the workspace)
|
||
go vet ./backend/...
|
||
gofmt -l . # must print nothing
|
||
go test -count=1 ./backend/...
|
||
go build ./platform/telegram/... && go test ./platform/telegram/... # Telegram connector (Stage 9)
|
||
go run ./backend/cmd/backend # /healthz, /readyz on :8080
|
||
|
||
cd ui && pnpm install && pnpm check && pnpm test:unit && pnpm build # the UI (Stage 7+)
|
||
pnpm start # UI mock mode: lobby -> game, no backend
|
||
|
||
docker build -f backend/Dockerfile -t scrabble-backend . # images (Stage 16); gateway embeds the UI
|
||
docker build -f gateway/Dockerfile -t scrabble-gateway .
|
||
docker compose -f deploy/docker-compose.yml config # validate the full contour
|
||
```
|
||
|
||
The `ui` module is a Node project (pnpm), **not** in `go.work`; it is the `ui` job
|
||
of the single `.gitea/workflows/ci.yaml` (Stage 16 folded the former go-unit /
|
||
integration / ui-test workflows into it). Committed edge codegen under `ui/src/gen/`
|
||
(regenerate with `pnpm codegen`); pnpm build-script approval lives in
|
||
`ui/pnpm-workspace.yaml` (`allowBuilds: esbuild: true`).
