Tasks: enterprise-gaming-combat

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/combat/ (@suaveplan/combat, 0.1.0, sideEffects: false)
• tsconfig.json, vitest.config.ts

Phase 2 — Error codes & constants

• src/error-codes.ts + src/constants/index.ts — damage type list, default crit multiplier

Phase 3 — Types

• src/types/common.ts + common.md

Phase 4 — Damage pipeline

• src/core/damage-pipeline/damage-pipeline.ts — resistance → armor → shield → health, modifier chain ordering
• Tests + docs

Phase 5 — Status effect

• src/core/status-effect/status-effect.ts — stacking policy, tick interval, duration countdown
• Tests + docs

Phase 6 — Combatant

• src/core/combatant/combatant.ts — applyDamage/applyHealing/applyStatus/tick/revive, OTel
• Tests + docs

Phase 7 — Combat manager

• src/core/combat-manager/combat-manager.ts — register/unregister, processHit, tick all combatants, events
• Tests + docs

Phase 8 — Integration + property tests

• tests/integration.test.ts — full combat sequence: hit → death → revive
• tests/property.test.ts — damage pipeline: true damage ignores resistances; shield absorbs before health

Phase 9 — Pre-publish gate

• bunx turbo lint typecheck test --filter=@suaveplan/combat green
• 100% coverage
• Publish: bun scripts/publish.ts --package @suaveplan/combat
