Keep a log of your own build
An entry in a minute from a phone in the hangar: the date, the task, the photographs. Sections with how far along each is. The whole log taken out on any day, and kept with the aircraft after it flies. The Builders Log is part of the Hangar Flying membership, $99 a year, with the Panel Designer, MRO and the Marketplace.
