+# DGR ROCm and llama.cpp setup
+
+As of 2026-07-13:
+
+- Project ROCm runtime: `/run/media/popov/d/DEV/repos/d-popov.com/AI/.venv-rocm`
+- ROCm/TheRock build: `7.13.0a20260513`, target `gfx1151`
+- `rocm-sdk-devel` is installed. Its expanded SDK lives under the venv at
+  `site-packages/_rocm_sdk_devel`.
+- The wheel's redundant packaged payload was relocated to
+  `/home/popov/.local/share/rocm-sdk/7.13.0a20260513/rocm_sdk_devel` and symlinked
+  back into the venv because installing both packaged and expanded forms filled
+  the mounted drive. Do not reinstall it blindly; the wheel expands beyond
+  20 GB.
+- HIP llama.cpp source: `/run/media/popov/d/DEV/llamacpp/llama.cpp`, commit
+  `e920c523e3b8a0163fe498af5bf90df35ff51d25` (version 9991).
+- HIP build: `/run/media/popov/d/DEV/llamacpp/llama.cpp/build-hip`
+- HIP `llama-server` SHA-256:
+  `b6bb4da687dbde86e243ba006cef05919b7b97255cd7e2371e1d451220aca139`
+- Verified device: `ROCm0: Radeon 8060S Graphics`, `gfx1151`.
+- Model artifacts remain under `/run/media/popov/DATA/llm`; none were put under
+  `/home`.
+
+DGR-001's immutable contract remains CPU-only. GPU evidence uses the distinct
+signed `gpu-diagnostic` profile because llama-server process VRAM is not yet
+measurable by the benchmark driver. The profile must capture measured
+llama-server startup evidence for `ROCm0` and the actual offloaded/total layer
+count; configured `device` and `n_gpu_layers` values alone are not evidence.
+The accepted signer fingerprint is anchored in
+`.scratch/distributed-gguf-runtime/trusted-evidence-signers.json`.
