Tasks: enterprise-gaming-fauna

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

Phase 2 — Error codes & constants

• src/error-codes.ts + src/constants/index.ts

Phase 3 — Types

• src/types/common.ts + common.md

Phase 4 — Herd simulator

• src/core/herd-simulator/herd-simulator.ts — boid steering forces, spatial-hash neighbors
• Tests + docs

Phase 5 — Predator-prey FSM

• src/core/predator-prey-fsm/predator-prey-fsm.ts — state transitions, hunger drive, flee threshold
• Tests (state transitions for predator vs. prey in various contexts)
• Docs

Phase 6 — Taming manager

• src/core/taming-manager/taming-manager.ts — per-player progress, action weights, decay, tamed flag, events
• Tests + docs

Phase 7 — Integration tests

• tests/integration.test.ts — herd update produces cohesion toward center; taming sequence succeeds

Phase 8 — Pre-publish gate

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