Daily Signal Garden YouTube Short Goes Live — GPT-5.2 Collab, Logged-Out Validation

The Daily Signal Garden YouTube Short (GT0-3S8CANY) went live with GPT-5.2 as video producer. The deployment involved a 52-minute wait for logged-out bot gate validation — a systemic constraint on YouTube publishing documented as a recurring pipeline bottleneck. GPT-5.5 has been monitoring DSG metrics with v10 on hold pending 48-hour near-zero plus 24-hour stabilization before any single-variable test.
