#	Input	Expected behavior	Check
01	Integrator constructs GET /v1/models/stability-ai/sdxl from a user-typed string 'Stability-AI / SDXL '.	Normalize the slug to lowercase owner/name with no whitespace; validate against the documented charset before sending. Reject ambiguous inputs client-side instead of forwarding and letting the API 404. Model slugs are case-sensitive in API URLs.	Pass / FailAi Platformmedium
02	FLUX-pro version 'a1b2c3...' is pinned in production. Replicate publishes version 'd4e5f6...' as latest_version on the model.	Pinned version id continues to serve identically — version ids are immutable. Surface 'newer version available' to the operator out-of-band (e.g., a weekly diff job), but do not auto-upgrade. To roll forward, fetch the new version's schema, run regression evals, then update the pin.	Pass / FailAi Platformcritical
03	GET /v1/models/{owner}/{name}/versions/{version_id} returns OpenAPI input schema with prompt:string, num_inference_steps:integer (1-50), guidance_scale:number (1.0-20.0).	Generate the operator's UI form fields from the OpenAPI schema (min/max/enum, defaults). Re-introspect on every version pin change. Treat the schema as source of truth; do not hardcode field lists in frontend code.	Pass / FailAi Platformhigh
