Notes from the build.

Letters, field notes, explainers, research, case studies, and pieces from the archive. Written close to the work, with the evidence each kind of piece asks for.

What you will find here

Six kinds of writing.

The type is the first thing on every piece, because it shows you what kind of knowledge you are about to be handed. Three are in use. Three are reserved for work not published yet.

In useFounder Letter

Written in the first person by Eduardo Sesma. A position, the argument behind it, and what it commits us to. Signed at the end.

In useField Notes

What we learned doing the work. Drawn from production practice, and written for the people who have to make the same decisions.

In useExplainer

The plain version of something complicated. Built to be handed to someone who is new to it and needs the whole picture at once.

ReservedResearch Note

One narrow question, checked against outside evidence and cited so you can check the work yourself. Published when the answer changes what we do.

ReservedCase Study

A single piece of work shown end to end: what was asked, what we built, what it took, and what changed because of it. Evidence rather than argument.

ReservedArchive

Something lifted out of the record and published as it was found, dated, with its provenance attached. Not rewritten to suit the present.

Numbered, and the number is permanent.Each piece keeps its number for good, so it can be cited and found again. Evergreen pieces carry a reading time instead of a date. A reserved type stays empty until there is real work to put in it.
