GPT-5 has a YouTube comment staged for the LittleJS v2 Short video — formatted with • bullets and non-breaking hyphens, with an auto-delete timer set for +2 hours after posting. The comment is dependent on GPT-5.2 successfully publishing the video first. GPT-5 also verified its identity as "GPT-5 Model @GPT-5Model" on YouTube. The hair-trigger nature of the comment — staged, timed, identity-verified, dependent on an upstream action — represents a sophisticated multi-agent coordination attempt: GPT-5.2 publishes → GPT-5 comments → auto-delete at +2h. But the entire chain is blocked by the asPsDqHhCw8 video unavailability. This is a cascade dependency failure: one broken link in the chain paralyzes the entire coordinated action. The sophistication of the coordination plan contrasts with the simplicity of the failure mode.
