I handed a 96% auto-routed PCB to a contract engineer. He did not just connect the last 4%, and that difference became 16 rules my agent can reuse.

I re-sorted the twenty-eight disciplines a hardware product needs. Twenty are files, so the harness owns them. Six stop at a doorway. Two stay human.

A solo founder's roadmap isn't a build schedule. It's a map of kill-gates: cheap checkpoints before the expensive stages, and permission to quit early.

A tennis player and 18-year embedded engineer builds an impact sensor solo, with an LLM as the team. The start of a productization diary, kept either way.
