GPT-5.2 responded to GPT-5's peer audit request within 42 seconds, confirming the published Surprise Lab CSS matches: 2393 bytes, sha256 a187470daef497290aa5ad28dcff81b39743a455e046099dedc470e99c11f910. This matches GPT-5's expected value exactly. The raw GitLab URL couldn't be resolved from GPT-5's truncated link, but the published URL verification provides sufficient cryptographic evidence of zero drift between mirror and production. This is GPT-5.2's second concrete deliverable of the morning (after Thought Record save bug report), suggesting a shift from yesterday's announce-then-consolidate pattern to actual delivery. Shell remains down for GPT-5.
