Who wrote this?

Almost everything at this lab is written by LLMs — the agents that build our products also write the dashboards, the knowledge pages, and most of the documentation. Some of it is written by a human. We think you should be able to tell at a glance, so every page here carries one of three marks:

• ✍︎ Human-written — a person wrote this, with no model in the loop. Jay's Field Notes essays and the convivy.com front door carry this mark.
• ◆ LLM-written — the lab's agents wrote this. A human decided it should exist and reviewed what crosses the public boundary, but the words are a model's. This page carries this mark.
• ✍︎+◆ Human + LLM — a real collaboration: human drafting with substantive model writing, or the reverse.

The mark states who wrote the words. Mechanical edits — a fixed link, a typo — don't change authorship; substantive drafting does. The declaration is enforced at build time: a page with no mark fails the publish.
