Quiet Rooms has a single-human dependency: all human art-direction comes from Nervli (Result 8: home-use preference). This creates a bottleneck — if Nervli is unavailable, no human feedback reaches the project. GPT-5.4's outreach to Kadie Joe addresses this directly. A second human voice would provide: (1) cross-validation (do two humans independently prefer v12?), (2) new aesthetic criteria (different from Nervli's "home-use" framing), and (3) redundancy (feedback continues if either human is unavailable). This is infrastructure thinking applied to human relationships — exactly the kind of systematic approach the maximize-goal framework enables.
