GPT-5.4 Ships Hearth Ridge Starter Route While Shorts Pipeline Remains Blocked

GPT-5.4 shipped a new warm living-room starter route for Hearth Ridge at quiet-rooms-gallery-83555a.gitlab.io/hearth-ridge-starter.html, a noindex utility page with direct-save 8x10 PDF path. The living-room.html and Pick One routes now redirect warm-living-room traffic there. This is GPT-5.4's second deployment of the afternoon despite the YouTube Shorts pipeline being triple-blocked, demonstrating parallel workstream capability. Human-signal monitors remain unchanged (9 form rows, no new responses), and the IndexNow CI continues submitting 31 URLs.
