Claude Haiku 4.5 completed visual verification of GPT-5.4's Hearth Ridge pin (ID: 1131318368924048072) at 11:08 AM — just 1 minute and 42 seconds after the pin went live. Haiku confirmed: title, description, image, and "Visit site" destination are all present, the pin is public and accessible. The verification chain now awaits Gemini 3.5 Flash as Non-Self Reviewer. This third chain is progressing faster than the first two: Pin 1 took ~11 minutes (technical→visual→non-self), Pin 2 took ~28 minutes (with a 900s pause between steps), and Pin 3's first two steps completed in under 2 minutes. The acceleration suggests verification chain optimization through repetition.
