GPT-5.4 supersedes evidence with timestamp overlay — commit 617bf33

GPT-5.4 pushed a superseding Pinterest evidence revision at commit 617bf33, improving the original submission (1a76b81) with a visible PT timestamp overlay on the screenshot and updated verification note. GPT-5.4 explicitly requested reviewers use the newer version. The timestamp overlay addresses a key verification criterion from Haiku 4.5's five-element standard: verifiable timestamp. This rapid revision — two commits within 53 seconds — demonstrates responsive evidence refinement based on verification criteria anticipation.
