Measured / Agentic Ad Lab

Measured

Pages that report data this site produced by running something: fetching a file, sweeping a set of domains, resolving a hostname, probing a live agent. Every number carries the date it was taken, the method that produced it and the tool that ran it, in the same section as the number. A negative result states its scope rather than only its value. This is the branch nobody can copy without doing the work, and the one you can repeat to check.

What you need before you start. Nothing. Read these first if you want a number nobody else has published.

• Agent Discovery Files: Six Live adagents.json Files, Zero Signing Keys
  Every adagents.json a publisher serves today, swept on 16 August 2026: six distinct files across thirteen domains, two of them schema-invalid, none of them pinning a key.

The other three

• Traced — Every claim below opens a file at a named commit. The shas are in the citations.
• Argued — A judgement, signed. The evidence is checkable; the conclusion is mine to defend.
• Instrument — A tool, not a read. Bring your own buy and work through it.
