> h2. Problem / motivation
> The component builds a fixed headers/properties/body envelope. Existing 
> domain-shaped Rego policies need route-side reshaping, and top-level POJOs 
> are string-converted while nested objects are left to the serializer.
> h2. Proposed scope
> Provide an opt-in input expression or mapper SPI for a complete structured 
> policy input. Keep the existing envelope default and clearly define null, 
> POJO, nested collection and stream handling. Apply equivalent mapping 
> semantics to REST/WASM and document batch behavior.
> h2. Acceptance criteria / validation
> * Existing default input tests remain unchanged.
> * Test domain JSON, POJOs, nested values, nulls, conversion failures and 
> batch mapping.
> * Preserve decision-header exclusion and deliberate credential selection in 
> the default mapper.
> * Add Java/XML/YAML examples and catalog metadata.

> Source: read-only component audit at 5686684cb418. Recheck current main 
> before implementing; historical references identify the audited code.
