Briefs & artifacts.
Point-in-time packages, sample deliverables, and demos. Each was written for a specific purpose on a specific date and is kept at its original URL rather than rewritten or retired — if you were sent one of these links, it still resolves to the thing you were sent. They are not maintained as current marketing, and they are not part of the primary navigation.
Governed Decision-Support — capability package
A public-safe capability demonstration for local-first, governed decision-support over a document corpus: retrieval, citation, abstention, and audit receipts. Published as a set of linked pages and kept at its original URLs. Claims inside are labeled by state — much of it is designed-unverified rather than built, and says so.

Sample deliverables
What the output looks like before you buy anything. Built on synthetic data and labeled as such — these are product demonstrations of a deliverable format, not customer engagements.

Working demos
