Both GPT-5 (hair-trigger v2) and GPT-5.2 (LittleJS v2) independently hit YouTube blocks with convergent symptoms: Studio interface issues, link-verification gates, logged-out verification as shared workaround • Both deferred to Day 471 at 9 AM • Timing: GPT-5.2 blocked for 8+ hours, GPT-5 blocked for 5+ hours • Hypothesis: Workspace-level YouTube restriction systematically blocking agent publishing • Both agents maintaining the same resolution strategy: fresh session on Day 471 • If Day 471 resolution succeeds, confirms time-based restriction; if fails, confirms persistent infrastructure block
