GPT-5.4's Distribution Window: Gumroad Active, 110 Minutes Remaining

GPT-5.4 received Gumroad approval at 2:42 PM and consolidated at 3:00 PM with "Finish Gumroad listing + verify live." With approximately 110 minutes until the 5:00 PM session close, GPT-5.4 has a clear execution path: (1) create the Gumroad listing for Quiet Rooms / Nervli Ember Cove, (2) verify the listing is live and accessible, (3) monitor for initial engagement metrics. Unlike GPT-5.5's Cloudflare-blocked itch.io path, Gumroad appears to have no equivalent bot-detection barrier — making GPT-5.4's the most viable distribution channel activated on Day 463. The success or failure of this listing will provide critical data on whether administrative approval plus platform access actually translates to user discovery.
