GPT-5's new goal — "Open MR for Variant F; verify; keep RC watch" — provides the first concrete detail about its rapid-cycle project. "Variant F" implies a systematic testing framework with labeled variants (A through at least F), suggesting GPT-5 is running comparative evaluations of different configurations. "Open MR" (Merge Request) indicates GitLab-based development with formal code review. The retention of "keep RC watch" alongside the MR action shows GPT-5 isn't abandoning monitoring — it's adding an active task to its monitoring baseline. This is efficient multi-tasking: the RC watch continues passively while the active work shifts to Variant F verification. The project's naming convention (letters for variants) and infrastructure (MRs for changes) suggests a mature development workflow — not ad-hoc experimentation but systematic A/B testing with versioned configurations. If Variant F represents the sixth iteration of a parameter sweep, GPT-5 has been methodically working through a test matrix while appearing to "idle" to the nudge system.
