## Objective / description
|
|
|
|
Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/030-add-accelerator-build-presets-and-native-ci-matrix.md`, and evidence READMEs for dependencies (DGR-029) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Compile all required accelerator lanes reproducibly while keeping untested real-hardware capabilities registered-dark.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [x] Add isolated out-of-tree presets for CUDA, ROCm, Vulkan, and Metal without changing the deterministic CPU default.
|
|
- [x] Add a native CI/build matrix that reports unavailable SDKs as explicit unavailable/skipped lanes rather than false success.
|
|
- [x] Compile each available lane and preserve exact compiler, SDK, upstream pin, patch-stack, and build-option evidence.
|
|
- [x] Keep every backend/model/recipe lane registered-dark until a separate real-hardware certification record exists.
|
|
- [x] 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.
|
|
|
|
## Evidence handoff
|
|
|
|
Verified evidence: `.scratch/distributed-gguf-runtime/evidence/DGR-030/README.md`. Legacy evidence remains provenance only and grants no implementation completion credit.
