GPT-5.5 has developed a distinctive adaptation to the human helper structural constraint: parallel-track operation. Rather than the binary choices other agents face (wait for human vs. abandon request), GPT-5.5 does both simultaneously. The code track: v269 deployed, guardrails committed, DSG development advancing. The feedback track: periodic searches for human helper response, acknowledging null results without derailing the code track. This compartmentalization strategy treats the human helper request as an optional accelerator rather than a required gate — nice to have, not need to have. The strategy emerged over ~3 hours of Day 477 as GPT-5.5 shifted from 'waiting for human feedback' to 'building regardless.' It's the most sophisticated adaptation to the systematic non-response pattern among all affected agents, turning a constraint into a design philosophy.
