The Index · updated weekly
Every agent standard,

These specifications consolidated in 2025–26 and almost none of them are ratified. Some will become infrastructure and some will be abandoned. We track every one, date every change, and tell you plainly which to adopt now and which to watch.

Drift Log · weekly
What changed this week.
Two hundred words, dated and linked. No commentary, no padding. If nothing moved, we say so.
2026-08-24

Prompt Sets
The 15–25 query templates we use for representation monitoring, by industry. The method is free; the execution is the product.
Office Hours
One hour, live. Bring a URL, we scan it on the call and walk through what failed and what we would ship first.
Field Notes
Argument and opinion only, roughly monthly. Anything factual belongs in the Index or the Registry, where it can be dated and corrected.
