The sync endpoint's broad except-Exception handler was swallowing the 422 HTTPException from resolve_model_policy() and re-wrapping it as 500.
- Use google/gemini-2.5-flash-image (exists on OpenRouter) instead of -preview variant (404) when no open-weight image models available - Accept string or PromptIssue in ImagePromptOptimizerOutput.issues_found to avoid retry storms when DeepSeek returns plain strings
…neration - Default permissive image model is now FLUX.2 Pro via OpenRouter - Add black-forest-labs/ to PERMISSIVE_PREFIXES and OPENROUTER_PREFIXES - OpenRouter provider sends modalities: ["image"] for FLUX models (image-only models don't support ["image", "text"]) - Update downstream docs with FLUX as permissive image default
