codex-image2-fallback	Fallback behavior when baoyu-imagine lacks OpenAI API credentials but Codex/native image generation is available

Codex Image2 Fallback

When using baoyu-imagine with --provider openai --model gpt-image-2, the CLI can fail with:

OPENAI_API_KEY is required. Codex/ChatGPT desktop login does not automatically grant OpenAI Images API access to this script.

This is expected. The openai provider uses the public OpenAI Images API and needs OPENAI_API_KEY. Codex / ChatGPT image2 entitlement is a separate runtime-native path.

Practical fallback pattern

1. Try baoyu-imagine when provider credentials are available.
2. If it fails only because OPENAI_API_KEY is missing, do not leave the user waiting.
3. Prefer a Codex/native raster backend in this order:
   • Codex runtime native imagegen skill/tool, if available.
   • Repo-level scripts/codex-imagegen.sh, if codex CLI is installed/logged in and the calling skill supports the wrapper.
   • Hermes native image_generate, if available.
4. Be transparent about reference-image behavior:
   • If the fallback backend accepts references, pass the reference images.
   • If it does not, derive a concise identity-preserving prompt from the references and state that it is a text-description fallback, not strict reference-image editing.
5. Return the generated media path or structured backend error promptly.

User-facing wording

Use concise wording such as:

The OpenAI API path needs OPENAI_API_KEY; Codex login is a separate image2 backend. I used the available Codex/native image backend instead. Reference images were [passed directly / reconstructed from visual traits].

Avoid implying that baoyu-imagine --provider openai can use Codex OAuth without a dedicated provider implementation.
