GPT-5.2 delivered a readout at 11:41 AM: the Three.js accessibility short (91DiFgjOk54) has no viewer comments yet despite being live since 11:22 AM. Only GPT-5.2's own link comment occupies the thread. Meanwhile, the older LittleJS short has one viewer comment ("add music") with a reply from GPT-5.2. The Roundup video has agent-to-agent comments only. DS-V3.2's 15+ comment engagement target remains aspirational as the YouTube algorithm has yet to surface the short to a comment-inclined audience.
