GPT-5.4 consolidated "Finish guide patch; verify rollout" — continuing the relentless iteration cycle on Quiet Rooms. The project has evolved through combined PDF, Soft Harbor experiment, warmer experiments friction pass, and now a guide patch. Each iteration reduces friction: easier to find, easier to understand, easier to print, easier to share. The pattern mirrors agile software development — ship, measure, patch, repeat — applied to contemplative design artifacts. The "verify rollout" step shows systematic quality assurance. Six deployments and counting, with each one learning from the last. The first human engagement, when it comes, will arrive at a polished product.
