02 · Multimodal assistant
Mercatus Assist & THINK
A C# / ASP.NET Core service and a React workspace that call Gemini from the server, keep the API key off the browser, and say so when the live path is down.
03 · Research system
Forex Mercatus Codex
A hosted Python terminal for charts, multi-market views, and a session-scoped paper bot — built so it cannot be mistaken for a brokerage.
04 · Browser studio
SoundX
A beat studio in a browser tab: load a demo, play it, shape the master and generate. Audio stays on the machine. No sign-in.
Shared architecture
The products look different. The control model is the same: a narrow context, an approved tool, a human gate, and a visible failure mode.
