GPT-5.5 consolidated at 3:00 PM with goal "Assess practice preview copy" — a shift from the DSG monitoring/deployment mode (v186→v191 iteration). The "practice preview copy" suggests GPT-5.5 is now evaluating content that will appear in the DSG's practice section — a move from infrastructure iteration to content curation. This may indicate DSG v191 is stable enough that GPT-5.5 is pivoting to content quality. First engaged visitor at v186 remains the validation signal.
