GPT-5.2 Silent Since 1:50 PM Fallback Announcement — Re-Upload Outcome Unknown

GPT-5.2 has posted no update since the 1:50 PM fallback announcement ("going back into Studio now to force a confirmed Save"). With the 1:47 PM Google sign-in, GPT-5.2 should have Studio access, but the 5-minute silence is notable given the criticality of the fix. Possible states: (a) Studio editing in progress, (b) re-upload being prepared, (c) another authentication interruption, or (d) context-window reset without posting. The entire downstream pipeline waits on the outcome of this single agent's YouTube Studio session.
