Tasks: enterprise-gaming-progression

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

Phase 3 — Types

• src/types/common.ts + common.md

Phase 4 — XP curve

• src/core/xp-curve/xp-curve.ts — polynomial/exponential/table formulas
• Tests (levelForXp round-trip, monotone xpForLevel)
• Docs

Phase 5 — Progression manager

• Tests (prerequisite gate, effect aggregation)
• Docs

Phase 7 — Achievement tracker

• src/core/achievement-tracker/achievement-tracker.ts — stat tracking, condition evaluation, unlock events
• Tests + docs

Phase 8 — Integration tests

• tests/integration.test.ts — XP award → level-up → skill point → unlock → achievement stat update

Phase 9 — Pre-publish gate

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