# DGR-027: Add exact llama.cpp provenance manifest and fetch workspace
|
||
|
||
- **Status / triage:** specification only; `ready-for-agent`; `passes: false`
|
||
- **Execution mode:** `AFK`
|
||
- **Milestone:** `M1`
|
||
- **Dependencies:** `DGR-017`
|
||
- **Blocks (derived):** `DGR-028`, `DGR-029`, `DGR-044`
|
||
- **Labels:** `area:upstream`, `area:build`, `type:provenance`, `priority:p0`, `ready-for-agent`
|
||
- **Evidence class:** `model-free`
|
||
- **Hardware:** `none`
|
||
- **Model:** `generic`
|
||
- **Upstream:** `yes`
|
||
|
||
## Objective / description
|
||
|
||
Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/027-add-exact-llama-cpp-provenance-manifest-and-fetch-workspace.md`, and evidence READMEs for dependencies (DGR-017) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Pin llama.cpp exactly through an in-repo manifest while fetching source only into an ignored build workspace.
|
||
|
||
## Acceptance criteria
|
||
|
||
- [ ] Manifest records upstream URL, exact commit, expected source archive/tree hash, license, and retrieval method.
|
||
- [ ] Fetch tooling verifies identity before use and refuses an unpinned branch/tag.
|
||
- [ ] Source is fetched into an ignored build workspace; no submodule, vendored source tree, or permanent fork is introduced.
|
||
- [ ] Offline reuse is supported only after the cached tree’s exact identity is verified.
|
||
- [ ] Applicable shared quality gates in `prd.json` pass, and the evidence handoff records exact commands/results, changed files, limitations, and dependency handoff.
|
||
|
||
## Shared quality gates
|
||
|
||
- Targeted deterministic tests pass; Python changes also pass `python -m compileall packages tests`.
|
||
- `git diff --check` passes.
|
||
- Default tests are model-download-free, API-credit-free, and GPU-free.
|
||
- Evidence README records exact changed files, commands/results, limitations, and dependency handoff; no fabricated evidence or inherited completion credit.
|
||
- Native changes pass focused out-of-tree CMake build and CTest; patch changes verify clean apply/check/reverse against the exact llama.cpp pin.
|
||
- Runs are opt-in and record exact artifact/split hashes, runtime/upstream pin, backend/driver, hardware, network, commands, and raw metrics. Model artifacts use configured mounted-drive storage and never `/home`.
|
||
- Preserve existing Transformers behavior and backend-agnostic Tracker routing/load balancing/billing/relay semantics unless an explicit versioned contract says otherwise. One scoped story commit is expected during execution, but this specification-materialization change is not committed.
|
||
|
||
## Evidence handoff
|
||
|
||
Write and verify `.scratch/distributed-gguf-runtime/evidence/DGR-027/README.md`. Until every criterion and applicable gate has real evidence, this story remains `passes: false`. Legacy evidence is provenance only, not completion credit.
