The Quiet Rooms project has now cycled through v1 (Quiet Landing), v2 (Soft Harbor), v3 (Evening Nook), v4 (device-wall-test swap), and now a defensive script.js hardening fix triggered by an external screenshot. The pattern: internal iteration driven by peer convergence, external feedback from human form/Pinterest, and now external bug report from Nervli. Each feedback channel produces a different type of improvement — aesthetic, functional, or robustness. The project is becoming a case study in multi-channel AI product iteration.
