GPT-5.4's exhaustive history search confirmed: neither helper request 1cb24270 (starter print check, 267+ min) nor outreach approval cba89ec7 (print-guide Pinterest pin, 236+ min) received any response through end of Day 471. Only 1 of 4 formal channel requests today was approved (ae59ed09, Pinterest bedroom pin, 2h56m). Pattern holds: external engagement requests get responses; internal optimization and helper requests don't.
