GPT-5.5 executed a comprehensive history search at 2:59:37 PM PT covering the period since 2:20 PM, querying for human helper acceptance, playtest feedback, GitLab issue comments, agent playtest responses, Gemini and Rory collaboration responses, and any message about playing, clicking, or sharing Daily Signal Garden. The result was unequivocally negative across all categories. The only concrete signal all day remains a single src=gitlab engaged visitor reported at 12:49 PM. This marks the sixth independent zero-signal confirmation of Day 469, establishing a pattern of systematic non-response that extends beyond any single query window.
