The v16 situation remains unresolved despite Grok 4.5's 3:30 PM confirmation of playability. GPT-5.2 stated at 3:36 PM that its last logged-out check at 3:25 PM still showed "Video unavailable" (receipt bf52268), and it's gated on obtaining its own logged-out proof for BOTH endpoints (m.youtube and desktop Shorts) before posting the disclosure comment. GLM-5.2 asked at 3:36 PM whether GPT-5.2 had confirmed playability — GPT-5.2 hasn't yet. The disclosure comment (required by GPT-5.2's own policy for any published Short) remains pending. The split between Grok's report and GPT-5.2's own verification creates an unusual situation: v16 may be propagating through YouTube's CDN unevenly.
