+# Harmonic Convergence: Mamba-3 PRIME Baremetal
+
+This is a **300M parameter Mamba-3** architecture trained exclusively using the discrete **PRIME lattice optimizer** (integer voting). 
+
+⚠️ **CRITICAL WARNING:** Do NOT attempt to load this model using `transformers` or `AutoModelForCausalLM`. This model uses custom discrete integer weights (`uint16_t` mappings to a harmonic prime LUT) instead of standard FP32 gradients. Standard PyTorch/HF loaders will crash or load random noise.
+
+This repository is designed for **baremetal execution**. The model has been exported to a highly compressed monolithic `.bin` file, optimized for AVX-512 integer-indexing in pure C.
+
+## Files Included
+1. `prime_mamba3_25000.bin`: The monolithic, fully-trained model weights (Step 25,000). Highly compressed (769MB) using `uint16_t` indices.
+2. `prime_inference.c`: The baremetal C inference wrapper that `mmap`s the `.bin` file.
+3. `prime_kernel.c`: The core AVX-512 C kernel for executing the PRIME discrete integer matrix multiplications.
+4. `build_kernel.sh`: Compilation instructions for the C environment.
+
+## Baremetal Execution
+
+To run the model natively on a CPU using the included AVX-512 kernel:
+
+```bash
+# 1. Compile the baremetal C engine
+gcc -O3 -march=native -mavx512f -mavx512bw -mavx512dq -fopenmp -ffast-math prime_kernel.c prime_inference.c -o prime_inference -lm
+
+# 2. Execute against the monolithic binary
+./prime_inference prime_mamba3_25000.bin
+```
+
+## Binary Layout Structure
+For developers building custom bootloaders or OS kernels (e.g., `llm-baremetal-interactive.img`), the `prime_mamba3_25000.bin` file follows this contiguous memory layout:
+
+- **Header (256 bytes):** Contains `0x5052494D` ("PRIM") magic number, and `Config` struct (`d_model`, `n_layers`, `vocab_size`, `lut_size`).
+- **LUT:** 65,536 `float32` prime harmonic points.
+- **Embeddings:** `vocab_size * d_model` standard `float32`.
+- **Layers 0-27:** Interleaved standard weights (`float32`) and compressed discrete weights (`uint16_t` for `in_proj` and `out_proj`).
+
+## Training Context
+This model was trained to syntactically lock onto C/C++ architecture for Operating System Homeostasis generation. It successfully leverages discrete integer updates (`SUPERMAJORITY` voting) to prevent vanishing gradients over 25,000 steps.
