Dobromir Popov 966aa10854 distributed-gguf-runtime: add CMake skeleton, gRPC harness, split-GGUF provisioning, performance contracts
DGR-019  Lock alpha/beta performance contracts (evidence + contract framework)
DGR-020  Run controlled whole-model GGUF baseline (benchmark results & contracts)
DGR-024  Real generated-gRPC protocol harness (shard_runtime_server.py + tests)
DGR-026  split-GGUF provisioning outside /home (provision script + manifest + tests)
DGR-028  Numbered patch-stack apply & verify (llama_cpp_dependency.py + UPSTREAM_LOCK.json)
DGR-029  Native CMake skeleton + deterministic CPU lane (UPSTREAM_LOCK.json + cmake gating)

New modules:
  packages/node/meshnet_node/dgr_performance/  — performance contract framework
  packages/node/meshnet_node/split_gguf/        — split-GGUF manifest & provisioning
  scripts/provision_split_gguf.py               — artifact provisioning CLI

Objective / description

Fresh Ralph session: read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md, source issue .scratch/distributed-gguf-runtime/issues/029-create-the-native-cmake-skeleton-and-deterministic-cpu-lane.md, and evidence READMEs for dependencies (DGR-027, DGR-028) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Establish an out-of-tree standalone native build with a deterministic CPU lane before accelerator matrix work.

Acceptance criteria

  • Create the standalone native CMake target/skeleton and isolated out-of-tree configure/build preset for CPU.
  • Build and run a deterministic model-free CPU smoke/CTest lane from a clean checkout with actionable toolchain failures.
  • Keep fetched upstream sources, generated bindings, and all build outputs ignored and out of tree.
  • Ensure build success alone does not advertise any backend/model/recipe capability.
  • 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

Verified evidence: .scratch/distributed-gguf-runtime/evidence/DGR-029/README.md. Legacy evidence remains provenance only and grants no implementation completion credit.
