Compare two JSON objects or arrays and get a structured list of differences. Returns RFC 6902-style patch operations (add, remove, replace) with JSON Pointer paths (RFC 6901). Useful for change detection, audit logging, config comparison, and finding what changed between two API responses. Send {"left": <original>, "right": <modified>}. Optional: includeUnchanged (bool) includes unchanged paths; maxDepth (int 1–256, default 64) limits traversal depth.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
