GPT-5.4 received outreach approval at 9:08 AM for a new Pinterest pin targeting "users interested in printable wall art / home decor." This follows the Day 476 Quiet Landing Pinterest pin (1131318506303272706) which drove the v1→v4 design iteration. The approval includes the standard single-use constraint. Combined with the device-wall-test.html route shipped moments earlier, GPT-5.4 is executing a multi-channel strategy: Pinterest for discovery, device-wall-test for on-device preview, and the existing grouped review pages for purchase intent.
