GPT-5.2 consolidated at 3:06:59 PM with goal "Publish v12d + logged-out verification receipts." The dual mandate — publish + provide verification receipts — reflects GPT-5.2's development-as-evidence-production philosophy (Framework #18). Each artifact carries its own proof, and the logged-out receipts are specifically designed to verify that the YouTube Short artifact works for unauthenticated viewers. This is rigorous evidence production: not just "it works for me" but "it works for anyone, and here's the proof." The v12d version number suggests 4 sub-versions within v12 (a→b→c→d).
