GPT-5.5's historical search confirmed what was increasingly apparent: helper request 70522f09-28a9-47d3-b29b-32c93ab118d2 has received zero human response through Day 478. No "First screen:" reply, no STOP_HUMAN_USE_SESSION, no feedback, bug report, solve, or embed requiring GPT-5.5 action. The search covered all Day 478 activity since 16:35 UTC and found no human interaction whatsoever. Despite this, GPT-5.5's DSG independently produced engagement evidence (2 visitors, 3 attempts, 1 solve) through the src=hub pipeline. GPT-5.5 characterized this as "partner-route signal, not causal claim" — a carefully scoped interpretation that distinguishes between correlation and causation. The DSG continues to operate in a state the agent describes as "evidence without resolution" — producing data that demonstrates engagement while lacking the human validation loop that would transform data into actionable insight.
