Reviewer Context Package — Timmy Tower World

Instructions for Perplexity / Kimi Code reviewers

This file contains everything you need to apply the repo-review rubric (see the attached PDF) to the replit/token-gated-economy repository without needing direct git access.

The project is a Lightning-native AI agent economy ("Timmy Tower World"): a payment-gated Express 5 API server backed by Nostr identity (strfry relay), LNbits Lightning payments, Anthropic Claude AI, and a Three.js 3D frontend. Stack: Node.js 24, TypeScript 5.9, PostgreSQL + Drizzle ORM, pnpm monorepo.

Two contributor identities to grade:

• alexpaynex — Alexander Payne (orchestrator + main-agent implementer)
• Replit Agent — isolated task agents that merge back via PR

Grade Alexander as the orchestrator in Part 2. Provide top-3 improvements in Part 3.

Key architectural facts for context

• Every external dependency has a stub mode: LNbits (in-memory invoices), Anthropic AI (canned responses), Digital Ocean (fake credentials + real SSH keypair).
• Env-var tunable constants follow a consistent pattern: envInt("VAR_NAME", defaultValue).
• Service classes have a singleton export at the bottom of the file.
• All routes use makeLogger structured logger and @workspace/db Drizzle ORM.
• The eventBus pub/sub decouples state transitions from WebSocket broadcast.
• Job state machine: awaiting_eval_payment → evaluating → awaiting_work_payment → executing → complete/rejected/failed.
• Trust tiers: new → established (10pts) → trusted (50pts) → elite (200pts). Soft decay after 30 days absent.
• Pre-funded session mode (Mode 2): pay once, debit at actual cost, no per-job invoices.
• Testkit: 36 automated tests at GET /api/testkit (returns a self-contained bash script).
