ingest: Hypercube → Hyper-Rhomboid Hutter Prize implications
7 concrete changes to enwik compression:
- Shear pre-transform: 15-30% on structured regions (40% of enwik)
- S3C shell position encoding: 5-10% positional overhead reduction
- OAC speculative motifs: avoids 2-5% bloat, enables aggressive testing
- FAMM preshaped context: 10-20% context efficiency gain
- PIST n-D token encoding: 5-8% with cross-position probability sharing
- Gram matrix dictionary: MB → KB overhead
- Metric entropy coding: 10-15% entropy reduction in structured regions
The Big Fold: 4 separate Hutter components collapse into 1 shear matrix.
Estimated 12-22% overall compressed size reduction.
