I run local LLMs through real agent loops and write down where they break (agent-lab). I read MCP as infrastructure — what it can't do on iOS, why gateways became a category, where the protocol has no answer yet. And I treat quantitative trading as a data-engineering problem first.
Everything here comes with sources. When I was wrong, the correction stays in the text and is marked — not silently edited.
