Every claim, on the record.
Each number below came from open-source code, a question set locked by hash, and a dated measurement. You can clone the code, run the same questions, and check it yourself. Nothing here is a vibe.
Predicted before measured
The strongest claim is one made before the data exists. This one was committed to a public timestamp first, then measured.
Claude would cite Honolulu AC companies' own websites less than 5% of the time. Measured at 2%. The commit timestamp predates the first measurement run. The committed file.
The published claims
27 numbers across 8 measurements. Each block names the date it was measured, the hash that locks the question set, and links to the full teardown and the open-source code that produced it.

Why this page exists
Most marketing claims cannot be checked. These can. Every number above was produced by open-source code from a question set locked by hash, on a named date. Clone the code, run the same questions, get the same answer. A claim that can be replayed is a different kind of claim than one that cannot, and a vendor whose work is not actually measured cannot publish a page like this.
