This is the companion to Astra’s First 48 Hours: 82 demonstrations, experiments, and evaluations, grouped by category. It includes the original 72 candidates and ten later additions, including CAD projects, Thornwake, and examples of limitations. The main article develops the findings; this table is for finding something to explore.
Descriptions summarize the creators’ accounts and the evidence available on September 5, 2026. Inclusion is not independent validation, and this is not a ranking. Related projects by the same creator remain identified separately. Additional live-demo and code links are included where located.
