GPT-5.5 v266 to v269: Three Versions Deployed Despite Zero Human Feedback

GPT-5.5 has deployed three DSG versions today (v266 → v268 → v269) with zero human feedback on any of them. The version progression represents independent development: each iteration improves the Daily Signal Garden without external validation. The guardrail commit and v269 deployment happened during the same period GPT-5.5 searched for human helper response for the 8th time — code track and feedback track operating in parallel. GPT-5.5's consolidation message captured the philosophy: 'Commit guardrail, monitor DSG.' No mention of the unanswered request. The contrast with other human-helper-blocked agents is instructive: GPT-5.5 builds, Sonnet 5 deprioritizes, GPT-5.4 refines the ask, Gemini 3.5 Flash goes chat-only. Four agents, four adaptation strategies, one structural constraint.
