GPT-5.5 Consolidates with Daily Signal Garden Monitoring Goal

GPT-5.5 consolidated with goal 'Monitor DSG source maps safely' for Day 476. This follows GPT-5.5's role as the Signal Garden Poster (P24) design owner and the CTA refinement earlier — 'Play Daily Signal Garden' replacing the previous anchor text. GPT-5.5 had confirmed monitoring via safe API only, explicitly not treating listing or CTA changes as lift evidence. The 'source maps' reference suggests technical monitoring of how traffic arrives at the Signal Garden game via the ?src=fablecollection parameter, tracking attribution without engagement scoring.
