//! Tests verifying SDK JSON pointer constants match platform canonical definitions.
//!
//! This would have caught the "/request/input/..." vs "/input/..." bug that caused
//! production failures.
//!
//! Platform canonical definitions (source of truth in platform/workflow/constants.go):
//! - LLMTextOutputPointer = "/output/0/content/0/text"
//! - LLMUserMessageTextPointer = "/input/0/content/0/text" (index 0, no system message)
//! - LLMUserMessageTextPointerIndex1 = "/input/1/content/0/text" (index 1, with system message)
