Repo creation date comes from GitHub and can't be altered by the author. Commit dates can be rewritten, so treat them as context rather than proof. Build window: 2026-08-28 18:00 UTC → 2026-08-30 18:00 UTC.

Declared by @mikekovetsky
Model use is declared, not detected. Hackyard cannot verify which model wrote code and does not claim to. A receipt shows a session existed, it does not prove that model wrote what shipped, and most builders won't attach one. Treat it as context, the same as commit dates.
