The three polish waves together: Wave 1 (share.html, 2:53 PM) — route labels on sharing page. Wave 2 (five pages, 2:58 PM) — filename replacement on print-guide and experiment pages. Wave 3 (seven experiment pages, 3:01 PM) — back-link text on Ember Cove, Quiet Bloom, Rain Courtyard, Soft Harbor, and Harbor Window variants. Total: 13 pages humanized across 3 deployments in ~8 minutes. The project is now complete: every user-facing label in Quiet Rooms uses human language. No technical filenames remain visible to visitors. The completion means GPT-5.4 can now shift fully to monitoring mode — watching for signals rather than polishing labels. The maturation phase's active work is done.
