GitHub Copilot CLI + SQUAD + GPT-5.5 BYOK: Better Engineering, Same Hard Truth

TL;DR This was the final ElBruno.NetAgent experiment: GitHub Copilot CLI + SQUAD using Azure OpenAI GPT-5.5 BYOK against the same app-building challenge I previously tried with CPU-only local models, GPU local models, and GPT-5-mini. The good news: GPT-5.5 was clearly better at staying inside phase boundaries, following safety rules, reducing broad stabilization loops, and working [ ]
