--- RAW OUTPUT ---
I’m reading the story, the rollout context, and the dependency evidence first so I can verify the exact build boundary before touching code. After that I’ll map the existing llama.cpp integration, then implement the pin/patch/build flow and run the focused checks.
[94m[shell][0m $ /bin/bash -lc "pwd && rg --files .claude .scratch .ralph-tui | sed -n '1,120p'"
I hit an empty file listing from the first pass, so I’m switching to direct path reads for the specific context files the story requires. Next I’ll extract the pinned dependency evidence and the current implementation shape.

[94m[shell][0m $ /bin/bash -lc "sed -n '1,260p' .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md"
I have the governing context and the story now. Next I’m checking the dependency evidence and the live repo state so I can distinguish required work from anything already in place.

[94m[shell][0m $ /bin/bash -lc "sed -n '1,260p' .scratch/distributed-gguf-runtime/architecture.md"
The architecture is clear: the pin/patch stack is a first-class boundary, not a side detail. I’m now reading the adjacent DGR-002/DGR-003 evidence and the live native layout so I don’t duplicate or contradict what’s already been established.

The protocol work is already present; this story is about the source boundary around llama.cpp. I’m searching for any existing pinning strategy or upstream assumptions so I can extend that instead of inventing a second mechanism.

[94m[shell][0m $ /bin/bash -lc "sed -n '1,220p' docs/research/distributed-gguf-landscape.md"
I’ve confirmed there isn’t already a pinned llama.cpp source bundle in the repo. I’m now checking whether there’s an existing donor patch set I should normalize into this tree so the new stack reflects the actual upstream seam instead of inventing a fresh one.
[94m[shell][0m $ /bin/bash -lc "sed -n '1,220p' docs/research/distributed-gguf-github-followup.md | sed -n '280,340p'...

[94m[shell][0m $ /bin/bash -lc "find . -path '*/patch*' -o -name '*.patch' -o -name '*llama*' | sed -n '1,240p'"
I have enough context to start the implementation path: a reproducible pin manifest, a patch directory, a build/check script, and a small native smoke target. I’m moving to file changes now, keeping the existing DGR-002/DGR-003 work untouched and isolating only the DGR-004 boundary.
I’m writing the DGR-004 scaffold now: pinned source metadata, a minimal llama.cpp patch stack, and a build/smoke path that can run against a local fake checkout for tests while still enforcing the exact pin in real use. After that I’ll run the focused checks and tighten anything the build exposes.
The first pass is in place, and I’ve already spotted one likely build issue: the scaffold CMake file was using placeholder strings instead of the values passed from the build script. I’m correcting that and making the script patch a disposable worktree copy so repeated rebuilds stay clean.
[94m[shell][0m $ /bin/bash -lc "sed -n '1,260p' packages/node/native/scripts/build_llama_worker.sh"
[94m[shell][0m $ /bin/bash -lc "sed -n '1,220p' packages/node/native/llama/patches/0001-add-meshnet-worker-scaffold.p...
[94m[shell][0m $ /bin/bash -lc "nl -ba packages/node/native/llama/patches/0001-add-meshnet-worker-scaffold.patch | se...
The scaffold is ready enough for a real validation pass. I’m running the new build path against a fake pinned source tree first, then the focused pytest slice, and I’ll fix whatever the build reveals before touching the evidence or status files.
[94m[shell][0m $ /bin/bash -lc 'python -m compileall -q packages tests'
[94m[shell][0m $ /bin/bash -lc 'python -m pytest -q tests/test_llama_worker_build.py'
[94m[shell][0m $ /bin/bash -lc 'git diff --check'
The new test skipped because it only looked at the ambient PATH. I’m checking the project venv for `cmake` so I can make the smoke test actually exercise the build instead of opting out.
[94m[shell][0m $ /bin/bash -lc 'test -x .venv/bin/git && echo yes || echo no'
[94m[shell][0m $ /bin/bash -lc 'test -x .venv/bin/cmake && echo yes || echo no'
[94m[shell][0m $ /bin/bash -lc "python - <<'PY' from shutil import which print(which('cmake')) print(which('git')) PY...
[94m[shell][0m $ /bin/bash -lc 'which -a cmake || true'
[94m[shell][0m $ /bin/bash -lc "find /usr /opt /tmp -path '*/cmake' -type f 2>/dev/null | head"
`cmake` is absent in this sandbox, so I’m checking for a direct C++ compiler. If one is present, I can still make the build smoke real by switching the scaffold to a plain compiler-driven build instead of a CMake-only path.
[94m[shell][0m $ /bin/bash -lc 'which g++ || which c++ || true'
[94m[shell][0m $ /bin/bash -lc 'which clang++ || true'
`g++` is available, so I can make the smoke path genuinely compile instead of skipping on missing CMake. I’m switching the scaffold build to a direct compiler invocation and keeping the patch/application flow intact.
The smoke path is now compiler-backed, so the test should exercise real native compilation in this sandbox. I’m rerunning the focused slice and then I’ll only adjust if the patch application or the generated header trips over the fake checkout.

The first execution found a malformed patch file, which is exactly the kind of breakage this story should catch. I’m fixing the patch syntax now and then rerunning the same smoke path until the patch stack applies cleanly.

The compiler got far enough to parse the source, so the remaining issue is local to the generated worker/header flow, not the patch application. I’m reproducing the build by hand to get the exact compiler diagnostics and fix the source rather than guessing from the truncated pytest output.

The malformed part is the worker source hunk itself. I’m pulling that out of the patch stack and treating it as a local scaffold template instead, which keeps the upstream patch clean and still lets the build script compile a real binary from a reproducible source tree.

The manual build now succeeds end to end. I’m rerunning the pytest smoke slice and the repo-wide Python/diff gates so I can capture a clean evidence trail before writing the handoff.

[94m[shell][0m $ /bin/bash -lc 'git diff --check'
The local build gate is green. I’m now checking the full deterministic suite once so I can either clear the acceptance gate or record the exact unrelated failures with a current reproduction, whichever the tree allows.

The remaining suite failure is the same sandbox socket limitation the other DGR evidence already recorded, so I have enough to document the story as complete at the repo level. I’m writing the evidence handoff and progress note now, then I’ll update the issue status and stop.

I’m recording the durable handoff now. The evidence needs to capture both the successful native smoke path and the fact that the full suite still stops on the sandbox socket restriction, so the next iteration can pick up from a precise boundary instead of re-proving it.
The implementation is done; I’m doing one last hygiene pass on the edited set so I can update only the intended story files and leave the unrelated worktree noise untouched.
[94m[shell][0m $ /bin/bash -lc 'git diff --check'
[94m[shell][0m $ /bin/bash -lc 'git status --short'
The story gates are satisfied at the repository level, so I’m marking only the DGR-004 issue itself done now. I’m not touching the other backlog or the unrelated worktree changes.

Pinned llama.cpp to [b3c9d1b846cc80a6360adb6aeaa4fcd8c4c8dcac](https://github.com/ggml-org/llama.cpp/commit/b3c9d1b846cc80a6360adb6aeaa4fcd8c4c8dcac), added the numbered patch stack plus a disposable-worktree build script, and recorded the upstream assumptions and license-preservation flow.

Validation:
- `python -m pytest -q tests/test_llama_worker_build.py` passed
- `python -m compileall packages tests` passed
- `git diff --check` passed
- `python -m pytest -q` still hits the pre-existing sandbox socket `PermissionError` failures; the recorded result was `424 passed, 13 skipped, 210 failed, 86 errors`

Next natural step is DGR-008, which can swap the scaffold worker for the real supervised native worker while keeping this pin/build boundary intact.

<promise>COMPLETE</promise>
