- flux_local: prompt->image fully on-device via mflux (schnell/dev, steps,
quantize, seed, size). Both FLUX repos are HF-gated as of 2026-07 (schnell
included) — clean GatedRepoError surfaces with a hint; needs owner HF token.
- openrouter_image: prompt->image via OpenRouter chat/completions with
modalities [image,text]; parses data-URL images from the response; model
picker for nano-banana / nano-banana-pro. Gated on OPENROUTER_API_KEY.
- settings: openrouter_key added to vault (masked/redacted/env-injected)
- scripts/install_mflux.sh; venv installed
- A/B flow: run both with the same prompt, judge in Compare mode
