# DGR-070: Enforce the DeepSeek V4 Flash beta gate - **Status / triage:** specification only; `ready-for-human`; `passes: false` - **Execution mode:** `HITL` - **Milestone:** `M5` - **Dependencies:** `DGR-057`, `DGR-059`, `DGR-060`, `DGR-062`, `DGR-064`, `DGR-066`, `DGR-067`, `DGR-068` - **Blocks (derived):** `DGR-071` - **Labels:** `area:deepseek-v4`, `area:release`, `milestone:beta`, `priority:p0`, `gate:hitl`, `ready-for-human` - **Evidence class:** `release` - **Hardware:** `required` - **Model:** `deepseek-v4-flash` - **Upstream:** `yes` ## Objective / description Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/070-enforce-the-deepseek-v4-flash-beta-gate.md`, and evidence READMEs for dependencies (DGR-057, DGR-059, DGR-060, DGR-062, DGR-064, DGR-066, DGR-067, DGR-068) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Promote beta only after concurrency, resilience, long-context, MTP, scale, packaging, and speed gates pass. ## Acceptance criteria - [ ] Evaluate all beta metrics against DGF-004 without changing thresholds after observing results. - [ ] Require V4 parity, batching/fairness, bounded backpressure, failure recovery, long-context correctness, MTP evidence, and dynamic 10+ stage evidence. - [ ] Publish the exact certified hardware/backend/recipe matrix; all other lanes remain dark. - [ ] Decision is `beta`, `targeted optimization`, or `stop/rollback`, with unresolved failures listed explicitly. - [ ] 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-070/README.md`. Until every criterion and applicable gate has real evidence, this story remains `passes: false`. Legacy evidence is provenance only, not completion credit.
