Create `server/db/redisClient.js` that:\n   - Creates Redis client from REDIS_URL\n   - Exports common methods: `get`, `set`, `sadd`, `srem`, `zadd`, `lpush`, `ltrim`, `expire`, `del`\n   - Handles connection errors gracefully\n4.

Người chơi tự tay bấm đặt hạt gạo — đúng sai tự chịu, giữ nguyên cảm giác hồi hộp của Lô Tô đời thực.\n\n**MVP đầu tiên** sẽ chạy trên **web (mobile-first)** để thử nghiệm, sau đó chuyển sang **Zalo Mini App** khi ổn định.\n\n---\n\n## 2. Target Users\n\n| Persona | Mô tả |\n|---|---|\n| Người Việt 20–45 tuổi | Lớn lên với Lô Tô, muốn hoài niệm |\n| Nhóm bạn / gia đình | Chơi giải trí online cùng nhau |\n| Casual gamer | Thích game đơn giản, may rủi, vui nhộn |\n\n---\n\n## 3.

WebSocket Protocol\n\n### Namespaces & Rooms\n\n- Connection: `socket.io` default namespace.\n- Each game room is a Socket.io room: `socket.join(roomId)`.\n- Server broadcasts events to room; clients listen.\n\n### Client → Server Events\n\n| Event | Payload | Description |\n|-------|---------|-------------|\n| `create_room` | `{ betAmount, maxPlayers, highlightSeconds }` | Create new room, user becomes owner |\n| `join_room` | `{ roomCode }` | Join existing waiting room |\n| `ready` | `{}` | Mark ready; when all ready, game starts |\n| `place_grain` | `{ row, col }` | Place rice grain on card; validates row/col belongs to number not yet drawn |\n| `call_kinh` | `{}` | Player claims completed row; adds to pending claims set |\n| `chat` | `{ message }` | Send chat message to room |\n| `leave_room` | `{}` | Disconnect from room gracefully |\n\n### Server → Client Events\n\n| Event | Payload | Description |\n|-------|---------|-------------|\n| `room_created` | `{ roomId, code }` | Confirmation of room creation |\n| `room_joined` | `{ room, players[] }` | Current room state and player list |\n| `player_joined` | `{ player: { id, name, avatar, coins } }` | New player entered |\n| `player_left` | `{ userId }` | Player left |\n| `player_ready` | `{ userId }` | Player marked ready |\n| `game_start` | `{ drawnNumbers: [] }` | Game begins; initial state |\n| `number_drawn` | `{ number, pronunciation, readAudioUrl? }` | New number announced |\n| `highlight_end` | `{}` | Highlight window ended; freeze board for Kinh verification |\n| `kinh_claim` | `{ userId, timestamp }` | Someone called Kinh (UI update) |\n| `game_settled` | `{ results: [{ userId, valid, reward, penalty, balance_before, balance_after }] }` | Final results for all players |\n| `balance_update` | `{ userId, newBalance }` | Individual balance changed (in-game announcement) |\n| `chat_message` | `{ userId, name, message, timestamp }` | Chat broadcast |\n| `error` | `{ code, message }` | Generic error (e.g., insufficient coins, invalid move) |\n\n### State Machine (Room)\n\n```\nwaiting → playing → frozen → settling → settled\n          │         │\n          └─────────┘ (can cancel back to waiting if not started)\n```\n\n- `waiting`: Players join/ready. Bet amount locked from balance.\n- `playing`: Numbers drawn sequentially. Players place grains freely (even late).\n- `frozen`: After highlight ends for a number; board locks for ≤500ms to collect all Kinh claims.\n- `settling`: Server verifies all claims; computes rewards/penalties; updates balances.\n- `settled`: Room closed; users return to lobby.\n\n---\n\n## 4.

Authentication Flow\n\n### Phase 1: MVP (Anonymous)\n\n1. On first launch, generate `tempUserId` (UUID v4) and store in `localStorage`.\n2. Create anonymous `User` record in DB with that `temp_id` and 1000 starter coins.\n3. All subsequent actions associate with that `temp_id` via JWT signed by server (stateless).\n4. If localStorage cleared, user can recover by entering same `temp_id` manually (optional, keep simple).\n\n### Phase 2: Zalo OAuth\n\n1. In-app button \"Login with Zalo\" triggers `zalo.login()` via SDK.\n2. Server exchanges Zalo auth code for user profile (`zalo_id`, `name`, `avatar`).\n3. Server checks if a `User` with that `zalo_id` exists:\n   - If yes → normal login, return JWT.\n   - If no → create new `User` with `zalo_id`. Optionally offer merge: \"We found a local account. Merge progress? Yes/No.\"\n4. Merge flow: if user previously played anonymously with `temp_id`, and now logs in with Zalo, server calls `mergeAnonymousData(temp_id, zalo_id)` which:\n   - Transfers all coin transactions, room history, stats to the Zalo account.\n   - Updates `merged_at`.\n   - Marks old `temp_id` as merged (cannot be used again).\n5. After login, all future sessions use Zalo JWT.\n\n---\n\n## 6. Game Mechanics & Rules Engine\n\n### Room Lifecycle\n\n1. **Create/Join:**\n   - Creator sets `betAmount`, `maxPlayers`, `highlightSeconds`.\n   - Players join (must have ≥ `betAmount` coins). System locks `betAmount` from each player's balance (reserve).\n   - Owner starts when all ready or after countdown.\n\n2. **Draw Loop:**\n   - Server draws numbers 1–90 randomly without replacement.\n   - For each number:\n     - Broadcast `number_drawn` with Vietnamese pronunciation text.\n     - Start highlight timer (`highlightSeconds`).\n     - During highlight, players can still place grains.\n   - After highlight ends → emit `highlight_end` → **freeze** board briefly (300ms) to collect `kinh_claims`.\n\n3. **Kinh Verification:**\n   - Collect all `userIds` who called Kinth within freeze window → Redis sorted set.\n   - For each claimant:\n     - Check each grain on their card: is the corresponding number in `drawn_numbers`? All must be drawn.\n     - If any grain on number not yet drawn → invalid.\n   - Compute:\n     - Valid winners: each receives `(totalPot / numValid)` coins.\n     - Invalid claimants: each pays `roomBet` to *each remaining player* (including other invalid? Clarify — typically penalty to all who did NOT call invalidly). Implementation: penalty distributed equally among all non-calling players? Or to all other players? We'll follow PRD: \"đền bằng mức cược của phòng cho mỗi người chơi còn lại\" — so each invalid pays `betAmount` to every other player in the room (including other invalid?). That would be circular if both invalid. Typically penalty goes to the house (của phòng) or to valid players. Let's interpret: \"đền ... cho mỗi người chơi còn lại\" meaning to each other player. If two invalid, they pay each other? That's net zero. Safer: invalid pays `betAmount * (numPlayers - 1)` to the *pool* which is then distributed to valid winners? But PRD says \"thưởng từ tất cả người thua\" — valid winners get pot from all losers. So losers are those who called invalid Kinh? Actually loser is everyone who didn't correctly complete row. In traditional Lô Tô, if you call false, you pay each other player. That's consistent. So each invalid player pays `betAmount` to *each other player* (including other invalids). That means if two invalids, they each pay the other → net zero between them, but they both also pay to valid winners. We'll implement exactly that: invalid claimant transfers `betAmount` to every other player in the room.\n   - Compute final balances atomically in DB transaction.\n\n4. **Settlement:**\n   - Update `room_players.final_balance`.\n   - Log all coin transactions (`coin_transactions` table).\n   - Broadcast `game_settled` with results (for UI animation).\n   - Room status → `settled`; players can exit to lobby.\n\n### Concurrent Kinh Handling\n\n- Freeze window: 500ms after `highlight_end`.\n- All `call_kinh` events received during freeze are added to `room:{roomId}:kinh_claims` (Redis SADD).\n- After freeze, server processes all claims in one batch.\n\n---\n\n## 7. Anti-Cheat & Integrity\n\n- **Balance lock:** `betAmount` reserved at join; cannot place grain if insufficient balance.\n- **Server-side validation:**\n  - `place_grain` validates cell corresponds to number already drawn (no future placement allowed, but late placement allowed on already-drawn numbers? PRD says \"người chơi vẫn có thể đặt muộn (theo trí nhớ) bất cứ lúc nào\" — so yes, after number drawn, grain can be placed anytime. But server checks that the number is indeed in `drawn_numbers`.\n  - `call_kinh` only allowed if player's current row completeness matches drawn numbers.\n- **Rate limiting:** Per-user action limits (max 10 grain placements per second, 1 Kinh call per round) using Redis counters.\n- **Replay protection:** Each `place_grain` includes a client-generated nonce to prevent replay attacks.\n- **Audit log:** All game actions logged to `game_history` with timestamps for potential dispute review.\n\n---\n\n## 8. Testing Strategy\n\n### Unit (Jest)\n- Card position mapping utils.\n- Kinh validation algorithm (row completeness check).\n- Coin transaction calculation (penalty distribution).\n- Balance update functions.\n\n### Integration (Socket.io mocks)\n- Room creation flow.\n- Number draw and broadcast.\n- Freeze window and claim collection.\n- Settlement logic with multiple players (including edge cases: all valid, all invalid, mix).\n\n### E2E (Cypress)\n- Single-player join + watch game (spectator mode? Not required).\n- 2-player room: full game loop, verify balances pre/post.\n- 4-player concurrent Kinh: all valid, split pot; all invalid, massive penalties.\n- Network lag simulation: ensure eventual consistency.\n- Disconnection: player drops mid-game, balance still locked correctly.\n- Chat messages appear.\n\nCI: GitHub Actions runs Jest + Cypress on push to main.\n\n---\n\n## 9. Infrastructure & Deployment\n\n### Development (Local)\n\n```bash\n# Backend\ncd server\nnpm install\ndocker compose up -d  # PostgreSQL + Redis\nnpm run dev  # hot reload\n\n# Frontend\ncd client\nnpm install\nnpm start  # localhost:3000 (connects to localhost:3001 WS)\n```\n\n### Staging / Free Tier\n\n- **Frontend:** Vercel project linked to GitHub repo. Auto-deploy from `main` to `lotto-game.vercel.app`.\n- **Backend:** Railway.app (or Render) with Dockerfile. Exposes port 3001. Free tier with 512MB-1GB RAM, 5h monthly sleep acceptable for testing.\n- **DB:** Supabase free tier (PostgreSQL) + Upstash free Redis (10K commands/day).\n- **Env:** `.env` with DB URLs, JWT secret, etc.\n\n### Production (Zalo Mini App)\n\n- **Backend:** Railway/Render hobby plan ($5–10/mo) — always-on, no sleep.\n- **Frontend:** Build for Zalo Mini App:\n  ```\n  npm run build:zalo  # outputs to dist/zalo/\n  ```\n  Upload to Zalo Mini App console, configure server domain (HTTPS WSS).\n- **Database:** Upgrade Supabase to Pro ($25/mo) for higher limits, or switch to Neon serverless.\n- **Monitoring:** Add basic logging (Winston) + health endpoint (`/healthz`).\n\n---\n\n## 10. Phase Plan for ClawTeam\n\nWe will decompose into independent, parallelizable tasks for ClawTeam workers. Each worker will be assigned a bounded scope (a single component or service). Workers will self-review, then cross-review, then final review by orchestrator.\n\n### Phase 1: Foundation (2 weeks)\n\n1. **Backend scaffolding** (Node.js + Express + Socket.io + Docker)\n2. **Database setup** (PostgreSQL schema + Redis integration)\n3. **Auth service** (JWT, anonymous user creation, Zalo OAuth placeholder)\n\n### Phase 2: Core Gameplay (2 weeks)\n\n4. **Room management** (create/join/ready/leave)\n5. **Number draw engine** (randomization, broadcast, highlight timer)\n6. **Grain placement** (server validation, board state updates)\n7. **Kinh verification & settlement** (concurrent claims, balance updates, transaction logging)\n\n### Phase 3: Frontend Game UI (2 weeks)\n\n8. **React app setup** (Vite, Zalo adapter, routing)\n9. **Lobby components** (room list, create modal, waiting room)\n10. **Game board UI** (LottoCard, NumberBag, RiceGrain with Framer Motion)\n11. **In-game HUD** (players panel, Kinh button, chat)\n\n### Phase 4: Economy, Social & Polish (2 weeks)\n\n12. **Coin economy system** — daily bonus, faucet management, anti-inflation\n13. **Achievements system** — track milestones (e.g., \"First Win\", \"5 Wins in a Row\", \"Concurrent Kinh with 3 Players\") and grant coin rewards\n14. **Spin wheel mini-game** — daily free spin for coin prizes (non-profit, fun engagement)\n15. **Chat system** (basic text chat)\n16. **Profile & stats** (view balance, history, achievement badges)\n17. **Testing suite** (Jest + Cypress full coverage)\n18. **Docker & deployment** (compose files, CI/CD, free tier config)\n\n### Phase 5: Optional (Future)\n\n19. **Audio integration** (TTS + SFX)\n20. **Advanced features** (tournament mode, friend list, invite via Zalo, spectator mode, AI bots)\n21. **Zalo-specific integrations** (share to feed, invite friends, deep linking)\n22. **Admin panel** (moderation, analytics, coin adjustment)\n\n---\n\n## 11. Risks & Mitigations\n\n| Risk | Mitigation |\n|------|------------|\n| WebSocket scaling on free tier | Use Redis adapter for multi-process; monitor connection count; upgrade if needed |\n| Race conditions in concurrent Kinh | Atomic Redis operations + transaction; thorough E2E tests |\n| Balance manipulation (client-side tampering) | Server-authoritative; pre/post balance snapshots; audit log |\n| Zalo Mini App packaging issues | Start with web MVP first; test on Zalo dev tools early |\n| Free tier limits (Upstash Redis 10K/day) | Optimize commands; use PostgreSQL for some room state if needed; upgrade cheaply |\n\n---\n\n## 12. Success Criteria\n\n- ✅ Full game loop: create room → join → draw numbers → place grains → call Kinh → settle → correct balances.\n- ✅ Concurrent Kinh handling (multiple winners) works reliably.\n- ✅ No cheating via client manipulation.\n- ✅ Responsive UI ≥ 30 FPS on mid-range mobile.\n- ✅ Deployable to Vercel + Railway free tier and runs for at least 10 concurrent players.\n- ✅ Test coverage: unit 80%+, integration critical paths, E2E user journeys.\n- ✅ Ready for Zalo Mini App integration (build script and config ready).\n\n---\n\n## 13. Open Questions (for user)\n\n1. **Penalty distribution exact rule:** When multiple players call invalid Kinh, does each invalid pay `betAmount` to *every other player* (including other invalids)? This yields net-zero between two invalids but they both pay to valids. Confirm: Yes, follow traditional Lô Tô rule: false caller pays each other player. (We implemented that).\n2. **Chat moderation:** Should we implement any profanity filter or moderation for Zalo Mini App? MVP: no filter; production: add simple word blacklist.\n3. **Daily bonus implementation:** We'll implement a simple `/claim-daily` endpoint that grants coins once per 24h. Any other faucets (achievements, spin wheel) in v1? Keep minimal — only daily login for v1.\n\nPlease review this spec. Once approved, I will invoke `writing-plans` skill to generate detailed implementation plan, then spawn ClawTeam workers following the 3-tier review process you specified.\n\n---\n\n**Next steps:**  \n1. User review and approval of this spec.  \n2. Write design doc to `docs/superpowers/specs/2026-03-31-lotto-game-design.md`.  \n3. Invoke `writing-plans` to produce task breakdown.  \n4. Spawn ClawTeam workers per phase, assign independent tasks.  \n5. Workers self-review → cross-review → Sagi final review → merge.\n"}],"isError":false,"timestamp":1774948419353}}

That's fine - we're doing Task 2 to set up the database. I'll create the `server/db` directory structure and files.\n\nLet me create:\n- server/db/ directory\n- server/db/migrations/ directory\n- server/db/migrations/001_initial_schema.sql\n- server/db/index.js\n- server/db/redisClient.js\n- server/db/schema.test.js\n\nI'll also need a test runner (Jest). The package.json doesn't have Jest yet, so I'll need to install it or use a simple test runner. But the task says \"Use `pg` library in tests to connect.\" It doesn't specify Jest - it could be a simple Node test file run with `node`. I'll create a simple test file that uses `pg` directly and exits with appropriate code.\n\nActually, to make it a proper test that can be run with `npm test`, I should add Jest as a dev dependency and set up the test script. But the task says \"Write a failing test\" and \"Run the test to verify it fails initially\". It doesn't specify the test framework. However, the project doesn't currently have any test setup. I'll create a simple test script using Node's built-in assert or just exit codes, which can be run directly with `node server/db/schema.test.js`. Or I could add Jest. To be more professional, I'll add Jest. But let's check the instructions: \"Write a **failing test** `server/db/schema.test.js`\". That's a specific file path. It doesn't say to add test scripts. So I can write a standalone test script that uses the `pg` library and exits with code 0 on pass, 1 on fail. That's simpler and doesn't require modifying package.json.\n\nBut the specification says \"Testing Strategy\" includes Jest. So maybe they want Jest. But Task 2 is just about the migration and creating the test to verify the schema. I'll keep it simple: a Node script that can be run with `node server/db/schema.test.js` or add a test script. Actually, if I add Jest, I need to install it. Since I'm not supposed to run `docker compose up`, but I am supposed to run the test. The test will need to connect to the database. But the instructions say \"assume docker compose is running\" - meaning I should assume the DB is up. In my actual execution, I might not have Docker running. But as a subagent, I should execute the commands as requested. However, the \"Important\" note says: \"Do not actually run `docker compose up` — assume the environment is set up from Task 1. Just create the files and test accordingly.\" That implies that the DB might actually be running? It says \"assume the environment is set up from Task 1\" - so the containers should be up.\n\nBut looking at my current context, I'm in a container? Actually the host is a Linux system. The docker-compose.yml is in the project. I can check if the containers are running. However, the instructions explicitly say \"Do not actually run `docker compose up`\". So I should not start containers. But if they're not running, the test will fail due to connection refused. That's expected? Actually step 4 says \"Write a failing test\" that \"connects to the database (assume docker compose is running)\" - but it should fail because tables not created yet. So the test should try to connect; if it can't connect (due to DB not reachable), it should print the helpful message \"Make sure to run 'docker compose up -d' first\" and exit with failure. That's a type of failure. But step 5 says \"Run the test to verify it fails initially (tables not created yet)\". So we want it to fail because tables don't exist. It's okay if the DB is not running - that's also a failure but we should handle both. However, they specifically say \"assume docker compose is running\" in step 4, so they expect the DB to be up. Since the environment was set up in Task 1, maybe the DB is actually running. I could check.\n\nBut I'll proceed to create the files first, then run the test. If the DB is not running, the test will output the helpful message and fail, which is still a failure (but not the intended one). To properly demonstrate the workflow, I'd ideally have the DB running. But the instruction says not to run docker compose up myself. That suggests the test environment may already have it running, or I should just note that the test would fail. Since I'm a subagent executing these steps autonomously, I need to actually run the test. But if the DB is not up, running `node test.js` would error. I can handle connection errors in the test code and print the helpful message, then exit with code 1. That's acceptable.\n\nBetter: I'll check if the DB containers are running. If not, I'll skip the actual test run and just note that the test would fail. However, the task says \"Run the test to verify it fails initially\" and \"Re-run the test — it should now pass\". This is an expectation that I actually run it and observe the outcome. So I should attempt to run it. Let's check if the containers are running.\n\nActually, maybe the environment is already set up.

The instructions say \"Do not actually run `docker compose up` — assume the environment is set up from Task 1.\" So I'll treat the test as expected to fail because the DB is not reachable, and I'll write the test to handle that gracefully by printing the helpful message.\n\nBut wait - the whole point of Task 2 is to set up the schema and then run the migration. If I can't actually connect to the DB, I can't verify the test passing after applying the migration. However, as a subagent, I'm expected to complete the task and produce outputs: git status and commit hash after committing. The task says \"After committing, return git status and the commit hash.\" So I need to commit the changes. I can still create the migration file, the DB clients, and the test. I can simulate the process: I'll run the test; it will fail because DB not reachable; I'll note that. Then I'll apply the migration by running the SQL file. But I can't actually run `psql` either without a database. However, I can still execute the steps conceptually, or I can try to use `exec` to run `psql` if the command exists but connection will fail. But the instruction says \"Use `psql` via child_process or just note that the migration file is ready to be applied\". So I could just note that the migration file is ready. But step 6 says \"Apply the migration: run the SQL against the database\". That suggests I should actually execute it. But if there's no DB, I can't. However, maybe I can assume the DB is reachable. Let's re-read the instruction: \"Do not actually run `docker compose up` — assume the environment is set up from Task 1.\" This implies that the database containers are already up and running from Task 1. So maybe in this simulated environment, they are running. But my `docker` command didn't work because maybe Docker is not installed or I'm in a container without access. Could be that the host system has Docker but it's not mounted in this exec environment? The `exec` tool runs commands; maybe it's running in a sandbox without Docker. But the main agent (the user) might have Docker on their machine; when they run the subagent, the subagent's exec commands run on the host? The documentation says: \"Exec host (sandbox|gateway|node).\" Default is sandbox? I'm not sure. The tool definition: \"Run shell commands with background continuation. Use yieldMs/background to continue later via process tool.\" It doesn't specify where it runs. Likely it runs on the same host as the workspace. My earlier `docker` command failed because `docker` binary not found in PATH. That suggests the host doesn't have Docker CLI or Docker isn't installed. That seems odd for a system that runs Lotto game. But perhaps this is a simulated environment where Docker isn't available, but the user expects the subagent to simulate the actions? Usually OpenClaw subagents are expected to do real work. But if Docker isn't available, I can't demonstrate the full flow. However, the task is part of a larger ClawTeam multi-agent coordination. Perhaps the environment is set up such that I can still run the test and migration using the `pg` command line if it's installed?

It seems the environment doesn't have database clients installed, and Docker is not accessible.\n\nGiven these constraints, I need to interpret the instructions in a way that I can still \"complete\" the task. The task is a subagent task; my final output is to return git status and commit hash after committing. I should still create all the files, and run the test if possible. Since I cannot actually connect to a database, I'll write the test to handle connection errors and print the helpful message, then exit with code 1. That's still a failure as expected initially (tables not created). Then I'll need to \"apply the migration\". I could attempt to run the SQL via `psql`, but that would fail because `psql` not found or DB not reachable. But the instruction says \"Use `psql` via child_process or just note that the migration file is ready to be applied.\" So I can just note that the migration file is ready to be applied. That might be acceptable: I don't have to physically execute it if I can't. However, step 7 says \"Re-run the test — it should now pass\". If I don't actually apply it, the test would still fail. So to fulfill the task, I would need to have the DB running to demonstrate the passing test.\n\nMaybe the expectation is that I as a subagent should actually run these commands on the host, assuming the environment is set up. But my environment lacks Docker/PostgreSQL client. Could it be that I'm supposed to use Node's `pg` library to execute the migration directly from the test or a separate script? Yes! The migration can be applied by reading the SQL file and running it through the `pg` client. I could do that in my test or a separate script. Step 6 says: \"Apply the migration: run the SQL against the database (use `psql` via child_process or just note that the migration file is ready to be applied)\". It doesn't require `psql`; I can use Node's `pg` library to execute the SQL directly. And I can do that from the test script or a separate script. I could integrate the migration application into the test: if tables are missing, apply the migration and then re-check. But the instructions say to run the test, then apply migration, then re-run test. That's manual steps. Since I'm automating as a subagent, I could perform these steps sequentially in one script. But the test file is supposed to be a failing test initially. Then we run the migration externally, then re-run the test. I can do it with two separate commands: first run `node server/db/schema.test.js` (expect failure), then run a migration script, then run the test again (expect pass). But I need to actually apply the migration to the database. If the database is up and accessible, I can use Node's `pg` to run the SQL. But the database might not be up. The instructions say \"assume docker compose is running\" from Task 1. So the DB should be up. Even if I don't have `docker` CLI, the DB might be running and accessible on localhost:5432. So I can try to connect using `pg` library. If the connection fails (because DB not actually running), that's a problem. But I can check by trying to connect with a simple Node script. Let me try using `node` to require `pg` and see if I can connect. But the project doesn't have Node modules installed yet. I would need to run `npm install` in the server directory. That's fine; I can do that. The dependencies include `pg`. So I can `npm install` first, then create a script to apply the migration. But the test script itself will need to import `pg` as well. So the plan:\n\n1. Ensure server dependencies are installed: `cd server && npm install`. (But maybe already done? Since it's a fresh project, likely not. The workspace shows only package.json, no node_modules. So I should install.\n\n2. Create `server/db/migrations/001_initial_schema.sql`.\n\n3. Create `server/db/index.js` (DB client helper).\n\n4. Create `server/db/redisClient.js`. But Redis might not be installed or reachable either. But I'll create the client code. The test doesn't require Redis, only PostgreSQL.\n\n5. Create `server/db/schema.test.js` that:\n   - Tries to connect to DB using DATABASE_URL from env (or default to postgresql://postgres:postgres@localhost:5432/lotto)\n   - Queries information_schema.tables to check for existence of required tables.\n   - If connection error, print \"Make sure to run 'docker compose up -d' first\" and exit with code 1.\n   - If tables missing, exit with code 1.\n\n6. Run the test: `node server/db/schema.test.js` (or `npm test` if I add script). Expect exit code 1 (failure).\n\n7. Apply migration: I'll write a separate script `server/db/migrate.js` or just run the SQL via a Node script. Or I can even have the test run the migration itself if it detects missing tables? But the steps are separate.\n\n   I'll create a `server/db/applyMigration.js` script that reads the SQL file and executes it via the `query` function from index.js or directly using `pg`. Then run it: `node server/db/applyMigration.js`.\n\n8. Re-run the test: `node server/db/schema.test.js`, expect exit code 0 (success).\n\n9. Commit: `git add . ; git commit -m \"feat: database schema and clients\"`.\n\n10. Return git status and commit hash.\n\nThis is all doable with Node and `pg` if the DB is running. Since I'm not sure if DB is actually running, I'll attempt to connect. If connection fails, I'll output a helpful error and maybe skip the actual application and re-test? But the task expects that after applying migration, the test passes. If I can't connect, I can't demonstrate that. But the user knows the environment might not be ready; they said \"Do not actually run docker compose up\" meaning they don't want me to start containers. But they assume it's already running from Task 1. So it should be running. I can attempt to connect. If connection fails, maybe it's because the DB hasn't been started by the user, but that's okay - the test will fail with connection error and print the message. However, step 6 says to apply migration and step 7 re-run test should pass. If I cannot apply migration due to DB down, I can't progress. So I need to be able to connect.\n\nGiven that the docker-compose.yml uses default POSTGRES_PASSWORD=postgres, the DB should be accessible at localhost:5432 with user postgres, password postgres, database lotto. That's standard. I can try to connect using a simple Node script to verify if the DB is up. Let me do that quickly after installing dependencies.\n\nBut maybe the testing environment in OpenClaw has these services running as part of the host system? The host is 4353aa29e8c5. That's probably the system where OpenClaw is installed. Could be that Docker is available but my `exec` command didn't find `docker` because it's not in PATH for the subagent. I could try `docker` with full path? Or I could just try to connect to localhost:5432 using `nc` or `pg_isready`. But `pg_isready` not found. Let's try `node` to ping the DB.\n\nI'll first `npm install` in server to get dependencies. Then I'll write a quick script to test connection. But I can also just proceed and attempt to run the test; if it can't connect, it'll fail. Then for applying migration, I can also attempt and if fails, output message. Then the test after that would still fail. That wouldn't satisfy the requirement that after applying migration, the test passes. But I could simulate success if I can't connect? That would be falsifying. Better to do the actual steps if possible. Given the constraints, I'll assume the database is running and accessible. The user likely expects that the environment is set up. I'll proceed with the real actions and if any fail due to environment, I'll note that in my final message.\n\nActually, the task is to implement Task 2 as a subagent. The main agent wants the results. The main agent knows the environment. If the DB is not up, they'd see the test fail. But they want me to commit the changes and return git status and hash. That's the final output. So I need to commit regardless of whether I could actually run the test successfully. I should attempt to run the test and migration to demonstrate, but if it fails due to environment, I'll still commit the code. The instructions say \"Run the test to verify it fails initially (tables not created yet)\". That implies I should run it and see it fail. So I'll run it and capture output. If it fails with connection error, that's not the intended failure (tables missing), but it's still a failure. However, the test is written to handle connection error separately. So I should design the test to treat connection error as a distinct failure with the helpful message, not as \"tables missing\". That matches the requirement: \"If test fails because DB not reachable, print helpful message\". So that's acceptable. Then I'd try to apply migration; if that fails because DB not reachable, I'll skip or note. Then re-run test; still fail. That wouldn't meet the \"should now pass\" expectation. But the user might know that the environment is not ready, and they just want the code. The instructions might be a template; the subagent is to perform the steps if possible, but if not, it's okay. The final commit is the deliverable.\n\nI'll implement all the code, attempt to run the steps, and report the outcomes. If the DB isn't reachable, I'll state that and that the migration couldn't be applied, but I still commit the files. The main agent can run the migration later.\n\nGiven that, let's proceed. I'll:\n\n1. Create directory structure: `server/db/migrations` and `server/db` files.\n2. Write the exact SQL schema.\n3. Write `server/db/index.js` with pg pool and query helper with slow query logging.\n4. Write `server/db/redisClient.js` with ioredis.\n5. Write `server/db/schema.test.js` that checks tables.\n6. Optionally add a migrate script.\n7. Run the test, capture output.\n8. Attempt to apply migration using Node script (reading SQL file and executing via `index.js` query).\n9. Re-run test, capture output.\n10. Commit with message.\n11. Return git status and commit hash.\n\nLet's start.\n\nFirst, create the migrations directory and schema file:","thinkingSignature":"reasoning"},{"type":"text","text":"Now I'll create the database structure.
