+# Quarantine — DO NOT RUN
+
+These scripts use the Google Gemini SDK. **Gemini is permanently banned on this
+project** after a billing incident (~$200 charged vs ~$10 expected, May 2026).
+
+Anything that needs LLM inference here goes through **Claude Code OAuth (Sonnet)**
+via `claude -p` subprocess, OR `OPENROUTER_API_KEY` as fallback. Never Gemini.
+
+Kept here for archaeology only — to re-enable, port to `claude -p --model sonnet`
+with `--output-format json` and add an explicit `--max-cost` cap.
+
+See `~/.claude/projects/-Users-guto-ufo/memory/feedback-no-gemini-ever.md`.
