The lab book, drawn

The evolution of Mosey.

Mosey was built in fourteen working days spread over three months, with a lab notebook kept every one of them. This is that notebook drawn as a single graph. Time runs left to right. The bright line is the trunk: what the app still does today. Above it are the branches that left the trunk — grey and ×-ended where they were let go, dashed where they are still open. Below it, in copper, is everything that was the app for a while before something better replaced it. The arrows are the moments something was understood; the diamonds are the moments something broke. The quiet weeks are drawn as quiet, not as distance.

Hover anything — or tap it — for what happened and why, and for what was said at the time.

The shape of it: almost nothing you can see survived from the first month. The film behind the onboarding, the 3D world, the five Blue Zones villages, the breathing button, the grid of rings — every visual idea was the app for a while and then wasn't. What never moved is underneath: the pad speaking a standard protocol, proven in one day of Python in July, and one finding — get up every twenty minutes and move — that the whole app is a way of obeying.

The other shape is the two long quiet spells. The first came after the protocol worked and before there was an app. The second came after a single day of six pivots through what the walker should see, and it ended with the sentence the product now stands on: the actual idea is the pad starting walks by itself.

Drawn from the project's lab notebook and its commit history by a script, so it grows as the notebook does; every date is the notebook's. Mosey is built by Alexis Rondeau with Claude, and the verdicts quoted in the notes are Alexis's, said at the time. The branches still open, and everything else on the board, are on the backlog.
