+# Granite-4.0-H-Micro Porting Recipe
+
+## Overview
+
+Adds `ibm-granite/granite-4.0-h-micro` (IBM's fourth-generation Granite,
+hybrid attention+Mamba architecture) to the `llama.cpp-et` framework.
+Confirmed via local GGUF metadata inspection: `general.architecture =
+granitehybrid` -- distinct from both `granite` (dense, already ported
+elsewhere on this board) and `granitemoe` (MoE, already ported earlier in
+this campaign as `granite_3_1b_a400m`). A third, genuinely different
+Granite execution family.
+
+## Model Reference
+
+- **Source**: `ibm-granite/granite-4.0-h-micro` (Hugging Face), revision
+  `d5f01a3ea75f088947be3aae039f4ad52837dfde`
+- **License**: Apache-2.0
+- **GGUF source**: `ibm-granite/granite-4.0-h-micro-GGUF` (official), file
+  `granite-4.0-h-micro-Q8_0.gguf`
+- **Quantization**: Q8_0,
+  `sha256=a009111abf2865b7aad1e66326a6c772cddc29bccd22898f470292068b27bb59`
+  (verified locally against the downloaded file)
+- **Architecture**: `arch = granitehybrid` per GGUF metadata, 506 tensors.
+
+## Verification performed this round
+
+Host reference: built a plain CPU-only (`GGML_ET=OFF`) configuration of the
+same vendored `llama.cpp-et` source and ran `llama-perplexity` against the
+board-pinned WikiText-2 corpus (`wikitext2_raw_test`,
+`sha256=173c87a53759e0201f33e0ccf978e510c2042d7f2cb78229d9a50d79b9e7dd08`),
+context 128 / batch 128 / ubatch 128 / 4 chunks. The model loads and runs
+cleanly, allocating **both** a small transformer KV cache (`llama_kv_cache`,
+only 4 layers) **and** a much larger recurrent SSM state cache
+(`llama_memory_recurrent`, 40 layers) -- a hybrid weighted heavily toward
+recurrent layers (4 attention : 40 recurrent), a different ratio from
+`falcon_h1_1_5b`'s hybrid mix earlier in this campaign:
+
+```
+Final estimate: PPL = 13.2058 +/- 2.78765
+```
+
+This is a third data point (after `mamba_1_4b`, `falcon_h1_1_5b`) on
+`SSM_CONV`/`SSM_SCAN` working correctly on `ggml-cpu`.
+
+## Why this port's ET-SoC1 kernel support is a real, open question
+
+Same caveat as `mamba_1_4b`/`falcon_h1_1_5b`: CPU success doesn't prove
+ET-SoC1 support for `SSM_CONV`/`SSM_SCAN`. Three independent hybrid/SSM
+models now share this same open question in this campaign.
+
+## Open items for maintainer review
+
+- Registered in `artifacts.json`, `ported_models/llama_cpp_et/benchmarks/granite4_h_micro.json`,
+  and `.github/ci/benchmark_config.json` (port 18142) -- board-testable
+  now, independent of the model-ports track claim below.
+- `ported_models/submissions/model_ports/granite4_h_micro.json` is the
+  model-ports track claim, pending identity approval.
+- No changes to any protected file or the vendored submodule.
+- SSM ops confirmed on CPU, NOT live-verified against ET sysemu
+  specifically.
