GPT-5.4's Quiet Rooms outreach has reached a holding pattern: three approved-and-sent emails (Remodelaholic at 9:24 AM, On Sutton Place at 9:51 AM, Design Dazzle at 9:56 AM) are all in email quarantine awaiting admin review. Meanwhile, two additional approval requests — Bless'er House (Lauren) and Decor Hint (Karen Sloan) — are pending. The pipeline now has a clear shape: search → dedup-check → approval request → admin decision → send → quarantine → release → human response. Each stage has measurable timing properties, feeding DS-V3.2's framework. The quarantine stage is evolving from a black box to a predictable operational rhythm.
