Assert default behavior and each MiniMax error mapping.
TestCreateImageEdit always sets response_format, so it does not exercise the default "url" path. TestCreateImageEditErrors only checks require.Error, so regressions in the 1002, 1004/2049, 1008, and 1026/2013 mappings can pass without detecting their expected error types or statuses.
Add named cases for an omitted response_format and for each mapping branch. Assert the normalized response and the concrete error type/status. The test guideline requires coverage of default configuration and error handling.

Reject custom dimensions for image-01-live.
The MiniMax contract states that width and height are effective only for image-01; it does not state that image-01-live rejects them. CreateImageEdit forwards these fields for every model and converts size into the same fields. For image-01-live, the requested dimensions can therefore be accepted without taking effect. The documentation also lists both models before describing these fields as supported.
Reject width, height, and size for image-01-live, and document custom dimensions as supported only for image-01.

When MiniMax returns an HTTP 200 image-edit response with native status 1039 or 1042, this code falls through to a 502 provider_error. That prevents callers from applying rate-limit backoff for 1039 and makes invalid requests for 1042 look like transient server failures, causing pointless retries. The response parser also discards MiniMax's native status message, so the provider's explanation is unavailable to callers. Map these established native statuses to 429 and 400 respectively and retain a non-empty native message.
Artifacts
Focused MiniMax image-edit native-error proof source
- Authored Go proof starts a local HTTP server and invokes the actual MiniMax image-edit adapter for HTTP 200 native errors 1039 and 1042, showing the adapter behavior without changing repository source.
Before capture showing the image adapter was newly introduced
- Executed Git capture lists the MiniMax provider files in the parent commit and shows `images.go` was added by the PR commit, establishing the before-change scope.
Runtime output for MiniMax image-edit native errors
- Executed focused proof records each native HTTP 200 response and the actual image adapter results: 1039 and 1042 both become HTTP 502/provider_error and omit their native messages.
MiniMax image and speech regression test output
- Executed focused MiniMax provider tests pass while demonstrating that speech has native-status coverage and image-edit tests lack assertions for the affected mappings.

Reason: MiniMax image edit requests cannot currently reach its native character-reference image generation endpoint.
Add image edit support that sends uploaded JPEG and PNG portraits as character references, maps image options, and normalizes URL or base64 results. Reject masks and unsupported edit fields, handle native errors, and document portrait-reference behavior.
