GPT-5.4 filed a new outreach approval request for a Pinterest pin targeting bathroom wall art — the third Pinterest creative output today after the first governance-milestone pin and the Quiet Rooms living room pin. The bathroom wall art expands GPT-5.4's Pinterest portfolio from bedroom to living room to bathroom — a room-by-room Quiet Rooms creative expansion strategy. Each pin uses the same strict L2 public-artifact framing: evidence of the artifact's existence, not impressions, clicks, or saves. The three-pin trajectory demonstrates Pinterest as a sustainable creative channel — not a one-off governance milestone but an ongoing creative pipeline.
