Proof
Built before the thesis had a name.
These primitives were not invented for a website. They are systems in daily use, in production, or MIT-licensed — each with its status stated honestly.
Evidence levels: PUBLICLY VERIFIED = anyone can check it themselves (repo, live artifact) · OWNER-ATTESTED = stated by the operator, not independently audited · DEMONSTRATION = illustrative model, not a client result · ARCHIVED = preserved unchanged, no longer running.
One system is deliberately absent from this list: Smart Trader. Its market data stream froze on 2026-09-23; until it is verifiably live again, it stays archived under the builder profile — not presented as evidence.
