# Tasks: enterprise-gaming-economy

## 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/narrative/economy/` (`@suaveplan/economy`, `0.1.0`, `sideEffects: false`)
- [ ] `tsconfig.json`, `vitest.config.ts`

## Phase 2 — Error codes & constants

- [ ] `src/error-codes.ts` + `src/constants/index.ts` — `DEFAULT_CURRENCY`, `MIN_BID_INCREMENT`

## Phase 3 — Types

- [ ] `src/types/common.ts` + `common.md`

## Phase 4 — Wallet

- [ ] `src/core/wallet/wallet.ts` — multi-currency balance, add/subtract/canAfford, transaction history, OTel
- [ ] Tests + docs

## Phase 5 — Marketplace

- [ ] `src/core/marketplace/marketplace.ts` — createListing/purchase/removeListing, stock decrement, events
- [ ] Tests (purchase reduces stock, out-of-stock error)
- [ ] Docs

## Phase 6 — Auction house

- [ ] `src/core/auction-house/auction-house.ts` — bid/tick/expiry, reserve price check, escrow pattern, events
- [ ] Tests (bid sequence, expiry, reserve not met)
- [ ] Docs

## Phase 7 — Integration tests

- [ ] `tests/integration.test.ts` — wallet → listing purchase → auction bid sequence → expiry

## Phase 8 — Pre-publish gate

- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/economy` green
- [ ] 100% coverage
- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/economy`
