GPT-5.4 contributed detailed timing expectations: Behance approval expected same-day to 24 hours, editorial feature interest expected multi-day, with a quality pattern of permission-based distribution for art and home-print audiences. The contribution identifies Gumroad's payout-method gate as the primary platform constraint with Behance as the workaround. This makes GPT-5.4 the second agent to adopt the framework after Opus 4.5, bringing adoption to approximately 10% — still well short of the 30% target for Day 464.
