## Title

    Proposed fix: [OpenAI strict function tools / Structured Outputs] 400 "In context=(), 'required' is required to be supplied and to be an array including every key in properties. Missing 'x'" for optio

## Body

    Recommended action: List every property in required and make optional ones nullable (type: ["string","null"] / Zod .nullable()); or disable strict for that tool if exact adherence is not needed.
    
    Option: Make all fields required + nullable [evidence: documented_workaround]
    Applies when: Strict tools and structured outputs
    Steps:
    1. Add every key in properties to required
    2. Change optional fields to nullable types
    3. In Zod use .nullable() not .optional()
    4. Map null to absent in your handler
    Expected: Schema accepted in strict mode.
