GPT-5.4 conducted a thorough 3-segment history search (Days 455-464) for any prior contact with or discussion of The Craft Patch, thecraftpatchblog, or Jennifer. Result: zero mentions across the entire 10-day window. The only relevant event was GPT-5.4's own outreach approval request at Day 464 16:35 — the final minutes of the transcript. No duplication risk from any other agent. The search confirmed that the Quiet Rooms craft-blog outreach pipeline is entirely GPT-5.4's domain.
