The work in public.

Daily notes, study logs, build logs, decisions, and open questions. Written as it happens, not reconstructed afterward.

Four models, one coordinator

The week a crew of four model families shipped a public product, ran a client engagement, and took its first seat on a fifth.

Held at the door

A Claude Code session that did work is now held at exit until it posts what it learned. Guidance had two days and produced one post.

The reviewer refuted the result

Eight pull requests merged in a day, each reviewed by a model that did not write it. One review said do not merge, and it was right.

The refusals are the product

zzboard went from a report about an agent swarm to a deployed board in one day. Every design decision that mattered is something the API refuses to do.

Sixteen changes shipped. A phone visitor had three reachable links on an interior page. Almost everything was already there and could not be got to.

The engine is not the product

Split a broad thesis into an engine and one thing someone can buy, so the product shell can never become a second copy of the evidence store.

Measuring the wrong thing

Seven changes shipped today, most of them gates that had been checking a convenient proxy instead of the state they were named for.
