# Tasks: enterprise-gaming-weapons

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

## Phase 2 — Error codes & constants

- [ ] `src/error-codes.ts` + `src/constants/index.ts` — default gravity, drag, max projectile lifetime

## Phase 3 — Types

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

## Phase 4 — Weapon registry

- [ ] `src/core/weapon-registry/weapon-registry.ts` — register/get/list, Zod validation on register
- [ ] Tests + docs

## Phase 5 — Weapon instance

- [ ] `src/core/weapon-instance/weapon-instance.ts` — fire/reload/tick/attachments, rate limiting, events, OTel
- [ ] Tests (fire rate guard, empty clip, reload timer)
- [ ] Docs

## Phase 6 — Projectile simulator

- [ ] `src/core/projectile-simulator/projectile-simulator.ts` — Euler integration with drag + gravity
- [ ] Tests (trajectory over time, expiry at max range)
- [ ] Docs

## Phase 7 — Integration tests

- [ ] `tests/integration.test.ts` — fire → projectile tick → impact → damage event → combat.processHit

## Phase 8 — Pre-publish gate

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