# DGR-004 — Reproducible pinned llama.cpp patch stack
|
|
|
|
Status: **done**. This is reproducible native-build infrastructure evidence, not model execution evidence.
|
|
|
|
## Delivered boundary
|
|
|
|
- Pin: `ggml-org/llama.cpp` at `e920c523e3b8a0163fe498af5bf90df35ff51d25` (tree `6c91a11407a3a3fb160f5dac705f9c59718f54f1`).
|
|
- Ordered patch: `0001-cmake-reserve-meshnet-patch-stack-abi-marker.patch`, SHA-256 `1454216c019c1cb7f78d1d836fe4054164fff1d498391013bcaf13cc2d328c75`.
|
|
- The sole patch adds an interface-library CMake marker. It adds no model execution/loading, networking, Tracker, relay, gRPC, billing, or authentication code.
|
|
- `scripts/llama_cpp_dependency.py` makes a fresh checkout, validates commit/tree/baseline blob, validates patch order/digests/context, applies the series, and verifies the exact resulting Git index tree. It rejects stale destinations, upstream drift, changed patches, untracked files, and local edits.
|
|
|
|
## Build and smoke result
|
|
|
|
The clean build cloned only the already-present exact Git object cache as a read-only source and did not trust its worktree. CMake 4.4.0 and GCC 15.2.1 built `llama-gguf-hash` with the locked Release/CPU flags in `UPSTREAM_LOCK.json`; `llama-gguf-hash --help` passed with no model download or load.
|
|
|
|
llama.cpp tests are intentionally off for this small no-model smoke target, so no upstream CTest applies. Meshnet's focused native protocol suite passed independently. Exact results are in `commands.txt` and `results.json`.
|
|
|
|
## License, compatibility, and handoff
|
|
|
|
llama.cpp is MIT licensed. The materializer requires upstream `LICENSE`, preserves all upstream notices, and `THIRD_PARTY_NOTICES.md` requires including them in redistribution. No Mesh-LLM code or patch was adopted.
|
|
|
|
The lock records the patched upstream blob and resulting patched tree. Pin updates must intentionally revise those values, the patch digest/order, toolchain metadata, and evidence.
|
|
|
|
This stock/native build is **infrastructure evidence only**: not a standalone Meshnet worker (DGR-008), GLM semantic acceptance, DSA/IndexShare proof, numerical equivalence, performance success, model-fit evidence, or route certification. The stock dense-MLA fallback remains explicitly uncertified. DGR-001 CPU v1 remains `stop`; DGR-017 is a separate target contract. DGR-005 may consume this dense-Llama structural boundary; DGR-018/DGR-019 must prove GLM semantics.
