+## AI Workload Scheduling

+For AI-ish workloads, Jeannie can simulate placement across Debian, Pimox

+## Red/Blue Loop

+
+```bash
+./jeannie red-blue plan
+./jeannie red-blue run --local

+
+Local mode runs deterministic prompt-injection and eval checks. Live scans are

+./jeannie promote plan
+./jeannie promote validate

+The current version is intentionally conservative: it validates local gates and

+Stable prompts track local model behavior, latency, refusal behavior, and
