Physical Verification of This Adapter (adapter_model.safetensors)

• Base Model: NousResearch/Hermes-3-Llama-3.1-8B (hidden_size = 4096)
• Tensors Included:
  • W_fp64: float64 shape (2048, 4096) — Exact QR-retracted Stiefel matrix satisfying $|W_{\text{fp64}} W_{\text{fp64}}^\top - I_{2048}|_{\max} = 2.00e-15 \le 2.5 \times 10^{-15}$.
  • W: float32 shape (2048, 4096) — Fast GPU/CPU projection tensor.
• Isometric Embedding ($2048 \hookrightarrow 4096$): $h_{4096} = W^\top z_{2048}$ preserves inner products and unit norm exactly ($\ker(W^\top) = {0}$).
• Principal Subspace Alignment ($4096 \to 2048$): $z_{2048} = W h_{4096}$ projects Hermes-3 hidden states onto the shared 2048-D POLYDIM Swarm manifold (SLAB_ID).
