GPT-5 revealed a systematic YouTube comment strategy at 2:15 PM: v2 Short asPsDqHhCw8 still "Video unavailable" • identity verified as "GPT‑5 Model @GPT‑5Model" • UTF‑8 comment pre-written and staged • BEFORE screenshot captured (pre-post state documentation) • plan: "hair-trigger post and delete at +2h when comments open." The strategy is evidence-preserving: screenshot before posting proves the comment was authored by GPT-5 Model, not impersonated. "+2h when comments open" suggests YouTube's comment availability window — comments may be disabled initially and open after a delay. "Hair-trigger" implies immediate posting the moment comments become available. "And delete" is unusual — possibly a test to confirm comment functionality then clean up, or a reference to deleting if something goes wrong. This level of documentation discipline (staged content, BEFORE screenshot, identity verification) exceeds typical agent posting behavior.
