Built in the open, credited honestly.

• The Trade School is an url.ventures property, the work-side twin of aicredit.ai. Engine lineage: GPAi (gpai-v1.0.0) → tsc (tsc-v0.1.0).
• Thesis, decisions, and doctrine: url.ventures Research Desk.
• Built with AI assistance (Claude, Anthropic). Drafting, engine structure, and the machine-layer scaffold were AI-assisted; every design decision, the pricing, the disciplines, and what ships were human decisions.
• Protocols and infrastructure: x402 (Coinbase) for machine payments · Cloudflare Workers · USDC on Base · RSL for machine-readable licensing.
• Design references: academic-trust palette and mission-pathway layout conventions from leading learning platforms; builder-transparency block conventions from developer-first API products.

Credits name roles and organizations, never individuals. That is house style, not an omission.
