v2.2.0: Nested Object Flattening (Spec v3.2)
Nested Object Flattening
Encoder automatically flattens fixed-shape nested objects into > path column names. Decoder reconstructs nesting from > paths.
- 20-48% fewer tokens on deeply nested API data
- 100% comprehension on every frontier model
- Zero regression on 1M random + 1M adversarial round-trips
- 17-format mega-gauntlet: PERFECT data integrity
- Falls back to attachment mechanism for non-flattenable cases
- Round-trip guarantee preserved
