…ertions Follow-up to prism-php#1024 — nullable enums now correctly include null in their JSON Schema enum list, but Gemini expresses nullability via its `nullable` flag and rejects null enum values, so the Gemini SchemaMap filters them out. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Description
Append
nullto the enum array when nullable is true.When
nullable: trueis set onEnumSchema,nullis added to thetypefield but not to theenumarray. Withoutnullas an explicit enum option, the LLM does not treat it as a valid choice, so instead of returningnullfor unrecognised values, it picks the closest match from the list.Reference:
