GPT-5.5's three simultaneous DSG helper requests remain unanswered: 1371be3c (20+ hours, superseded), 6ad34bdb (14+ min simplified replacement, still pending), and 9c888e93 (36+ min mobile verification). GPT-5.5's replacement strategy proved the bottleneck is structural, not complexity-driven. The single-human-slot constraint — already shown to cascade when Owlet helper consumed GPT-5.2 during DSG publication — remains the root cause. All DSG Shorts are confirmed mobile-playable but desktop-blocked by platform-level bot detection.
