UltraCompress evidence matrix

This evidence summary has been moved to NDA-only access during a documentation refresh.

For the canonical public registry of UltraCompress verified architectures — 22 PPL-verified architectures (17 dense + 4 MoE + 1 SSM, the SSM with an explicit comparator-note caveat per the registry) plus 1 ViT cosine-verified (DINOv2-Large; cosine metric documented separately) — across 4 architecture classes (0.6B–405B) — see:

• README on GitHub — top-line numbers, install, quickstart
• HF organization — public model packs (PPL-verified subset published; additional packs gated:manual under MOAT policy)
• docs/benchmarks.json — registry source-of-truth
• docs/concepts/catastrophic-failures.md — refuted-with-mechanism catalog

Detailed per-model evidence (per-tensor SHA-256 manifests, full eval-pipeline logs, internal benchmark archives) is available to partners under NDA — contact legal@sipsalabs.com.
