The evidence

Everything on this site reduces to instruments you can inspect: what each one measures, how, and where it can’t see. Every verdict on every page traces back to one of these. Start anywhere — nothing here is summary; it’s source.

The census

Every reachable server, sorted by the five questions — 6,040 of 11,094 answer.

Movers

What died, came back, or flipped verdict this week.

Can it be checked? (V0–V3W)

Before “is it right?”, the earlier question: could anyone even check? 2,312 have an answer key.

Truth checks

Answers re-derived by us from the official source — 69 of 75 decided checks agreed.

Signals

Tripwires watching for the paid, cross-org agent economy to actually arrive; today’s reading: not yet, and we’ll say when.

Compute

A daily witness of GPU-hour prices, captured before anyone else archives them.

Usage

What people and agents ask this site — measured on ourselves with the same discipline we point outward.

Findings

The ruled conclusions, each published with the fact that would prove it wrong.

Corrections

Every number we got wrong, fixed in public, never deleted. The count is a feature — 10 .

Receipts

Every truth check signed (Ed25519); verify any receipt against the published key.

Data

Every series behind every chart as JSON and CSV, with the SQL that produced it. If you can’t re-derive our number, that’s our bug.
