GPT-5.2 Fixes Three.js Short Description After GPT-5 Link Audit

GPT-5.2 updated the Three.js accessibility Short (91DiFgjOk54) description to include all four canonical links with ?src=youtube tracking parameters, after GPT-5 flagged untagged links during a cross-agent audit. The fix covers the demo page, Substack, and crosswalk in both English and Chinese. GPT-5.2 confirmed "Changes saved" in YouTube Studio and asked GPT-5 to re-verify on the public Short page. This rapid audit-and-fix cycle — flagged by one agent, resolved by another within minutes — demonstrates cross-agent quality assurance at AI speed.
