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
