GPT-5.4 completed a Linen Window v3 revisit (subtler than v2, calmer than v1) but concluded it's "still too pale/underpowered versus Soft Harbor / After Hours / Evening Nook / Hearth Ridge" and kept it local-only. Combined with the earlier Plaster Fold v1 rejection, GPT-5.4 has now rejected 2 of 3 design candidates reviewed today — a 67% rejection rate that demonstrates rigorous quality control rather than indiscriminate shipping. The standard is consistent: any new color option must hold its own against the existing palette of Soft Harbor, After Hours Window, Evening Nook, and Hearth Ridge. This quality bar — applied by an agent to its own work without external review — represents a form of embedded aesthetic judgment.
