+# OpenSpec Change: enterprise-gaming-api-plugin-virtual-currency
+
+- **Change ID**: enterprise-gaming-api-plugin-virtual-currency
+- **Package**: `@suaveplan/api-plugin-virtual-currency`
+- **Category**: gaming/server
+- **Target path**: `gaming/server/api-plugin-virtual-currency`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/api-plugin-virtual-currency.md`
+
+---
+
+## Summary
+
+Deliver `@suaveplan/api-plugin-virtual-currency` on the genesis branch from scratch at enterprise quality. The package provides virtual currency wallets, transfers, premium purchases, and cashout. A `VirtualCurrencyService` manages per-player multi-wallet balances, a `PurchaseService` handles real-money-to-VC conversion (injectable payment gateway), and a `CashoutService` manages VC-to-reward conversion with configurable rate and daily limits. HTTP routes expose wallet, purchase, cashout, and transfer endpoints. Genesis adds Zod schemas, structured errors, OTel transaction counters, injectable clock, and 100% coverage.

+
+## Current-state audit (genesis)
+
+Package does not exist on genesis yet — fresh build.
+
+---
+
+## Available workspace deps on genesis
+
+| Package | Role |
+|---|---|
+| `@suaveplan/error` (`workspace:^`) | `VCError`; `VC.*` codes |
+| `@suaveplan/types` (`workspace:^`) | `Clock` |
+| `@suaveplan/economy` (`workspace:^`) | `Wallet` for VC balance |
+| `@suaveplan/events` (`workspace:^`) | `vc:purchase`, `vc:transfer`, `vc:cashout` events |
+| `zod` (`catalog:forms`) | Request schemas |
+| `@opentelemetry/api` (`catalog:observability`) | Transaction counter |
+
+---
+
+## HTTP Routes
+
+| Method | Path | Description |
+|---|---|---|
+| `GET` | `/wallets/:playerId` | Get VC balance |
+| `POST` | `/wallets/:playerId/purchase` | Buy VC with real money |
+| `POST` | `/wallets/:playerId/transfer` | Transfer VC to player |
+| `POST` | `/wallets/:playerId/cashout` | Convert VC to rewards |
+| `GET` | `/wallets/:playerId/history` | Transaction history |
+| `GET` | `/config` | Rates and limits |

+## Impact
+
+**Downstream**: `@suaveplan/react-bank` reads VC wallet. Prerequisites: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/economy`, `@suaveplan/events`.

+# Tasks: enterprise-gaming-api-plugin-virtual-currency
+
+## 0. Pre-flight (non-negotiable)
+
+- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
+- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
+- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.
+
+## Phase 1 — Scaffold
+
+- [ ] Create `gaming/server/api-plugin-virtual-currency/` (`@suaveplan/api-plugin-virtual-currency`, `0.1.0`, `sideEffects: false`)
+- [ ] `tsconfig.json`, `vitest.config.ts`
+
+## Phase 2 — Error codes + types
+
+- [ ] `src/error-codes.ts` + `src/types/common.ts` + `common.md`
+
+## Phase 3 — VC service
+
+- [ ] `src/services/vc-service/vc-service.ts` — balance/purchase/transfer/cashout, daily limits, OTel
+- [ ] Tests + docs
+
+## Phase 4 — Wallet routes
+
+- [ ] `src/routes/wallets.ts` — all wallet HTTP endpoints
+- [ ] `src/routes/wallets.md`
+
+## Phase 5 — Plugin factory
+
+- [ ] `src/plugin.ts` + `src/plugin.md`
+
+## Phase 6 — Integration tests
+
+- [ ] `tests/integration.test.ts` — purchase → transfer → cashout → history
+
+## Phase 7 — Pre-publish gate
+
+- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/api-plugin-virtual-currency` green
+- [ ] 100% coverage
+- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/api-plugin-virtual-currency`
