# 10 — Pass local real-model two-process acceptance

Status: ready-for-agent

## Mandatory fresh-session context

- Read [RALPH-CONTEXT.md](../RALPH-CONTEXT.md) completely before changing code.
- This issue is `DGR-010` in [prd.json](../prd.json).
- Read the evidence README for every dependency listed below.
- Inspect current code and `git status`; historical text and previous agent claims are not evidence.

## Description

As a release engineer, I need real local distributed parity before involving network variability.

## Expected durable outputs

- Real local two-process commands and configuration
- Raw parity, memory and performance results
- evidence/DGR-010/README.md

## Acceptance criteria

- [ ] Two local worker processes open disjoint dense-Llama ranges from the certified Artifact.
- [ ] Prefill and at least 32 greedy decode tokens match whole-model llama.cpp within the certified tolerance.
- [ ] Each worker retains only its own tensors and Hot KV State.
- [ ] Four concurrent Route Sessions pass isolation and cleanup checks.
- [ ] Report TTFT, prefill/decode throughput, seam bytes/latency, worker RSS/VRAM, KV memory, batch size, and queue time.
- [ ] Killing one worker produces a bounded structured failure rather than a deadlock.
- [ ] Targeted pytest tests pass
- [ ] python -m compileall packages tests passes for Python changes
- [ ] git diff --check passes
- [ ] Default tests remain deterministic, model-download-free, API-credit-free, and GPU-free
- [ ] Full deterministic pytest -q passes, or the exact pre-existing unrelated failure is recorded with a clean-tree reproduction
- [ ] Pinned native C++ target builds and focused CTest/protocol tests pass where native code is touched
- [ ] llama.cpp patch stack applies cleanly to the exact pinned commit where patch code is touched
- [ ] Real-model execution is opt-in through MESHNET_ENABLE_REAL_INFERENCE_TESTS=1 and records exact artifact/runtime/hardware evidence
- [ ] Model artifacts remain on the configured mounted-drive storage and never under /home
- [ ] Read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md and this story issue completely before changing code
- [ ] Read and verify every dependency evidence README before relying on dependency behavior
- [ ] Preserve all pre-existing working-tree changes and stage only files belonging to this story
- [ ] Write .scratch/distributed-gguf-runtime/evidence/DGR-010/README.md with files changed, exact commands and real results, limitations, compatibility notes, and dependent-story handoff
- [ ] Update only this story issue to Status: done after every acceptance criterion and quality gate passes

## Dependency handoff

- `DGR-009` must have `passes: true`; read `../evidence/DGR-009/README.md` and verify its referenced files/commands.

## Finish contract

- Create the task evidence directory and durable handoff required above.
- Preserve real failures and blockers; never fabricate benchmark, model, test or hardware output.
- Change this issue to `Status: done` only after all criteria pass.
- Emit `<promise>COMPLETE</promise>` only after the evidence handoff exists.
