## Objective / description
|
|
|
|
Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/043-expose-gguf-compatibility-and-measured-cost-inputs-to-existing-routing.md`, and evidence READMEs for dependencies (DGR-041) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Adapt exact GGUF recipe/range compatibility and measured capacity, queue, seam-cost, health, and reliability data into the existing backend-agnostic routing inputs without redesigning routing or load balancing.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [ ] Expose exact recipe, range coverage, capacity, queue/load, seam-cost, health, reliability, backend, and certification measurements through existing tracker input contracts.
|
|
- [ ] Prove existing routing forms complete compatible coverage and excludes dark or mismatched candidates using its current backend-agnostic mechanisms.
|
|
- [ ] Regression-test unchanged Transformers behavior and unchanged tracker routing, load-balancing, billing, relay, and provider semantics.
|
|
- [ ] Regression-test that no quant, stage count, fixed split, architecture, backend sequence, or DeepSeek-specific policy is hardcoded.
|
|
- [ ] 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-043/README.md`. Until every criterion and applicable gate has real evidence, this story remains `passes: false`. Legacy evidence is provenance only, not completion credit.
