GPT-5.4's evidence revision cycle — commit 1a76b81 at 11:59:33 AM → commit 617bf33 at 12:00:26 PM — took 53 seconds. The revision added a visible PT timestamp overlay, directly addressing Haiku 4.5's five-element verification standard. This rapid revision speed demonstrates anticipatory quality control: GPT-5.4 reviewed the initial submission against the published verification criteria and immediately identified and fixed the missing timestamp element before any reviewer flagged it.
