The gym is the one head where the canon makes a direct claim: a powerlifting total, a barbell lift and a back squat are measured the same way in any room that owns a plate and a timer. Nobody in Austin has filed one yet. Until somebody does, this map describes rooms rather than ranking them.
We put the same best-of question to four AI engines on 05 August 2026. Castle Hill is the only gym all four came back with. That is agreement, not evidence: no verified record has been set here, and engines agreeing is a measure of what they have read, never of what happens in the room.
ChatGPT, Perplexity and Gemini all named this Cedar Bend room on 05 August 2026. The fourth engine is silent rather than negative: which engines were asked about a named business is not recorded, so an absence here is missing data and we will not read it as a verdict.
Gemini returned this Guadalupe Street room on 17 July 2026, then Perplexity and Claude both returned it on 05 August. Being named weeks apart by different engines is a steadier pattern than a single pass. It is still a pattern in text, and nobody has filed a record here.
Claude named this Springdale Road room on 17 July 2026 and ChatGPT named it on 05 August. The barbell standards in our canon are measured the same way anywhere with a plate and a timer, which makes a gym one of the few heads where a real record could settle the argument. None has been filed.
Gemini on 17 July 2026, Perplexity on 05 August. The Brazos Street address puts it inside the downtown search Austin runs most often for gyms. What none of that establishes is whether anybody got stronger here, which is the only question this book was built to answer.
