# Distributed GGUF Runtime milestones

> **Specification status:** planning artifacts only. No distributed GGUF runtime is implemented. DGR-017 cleanup is complete; no runtime implementation story has completion credit. `prd.json` is authoritative.

## M0 — Truth and contracts

- **Stories:** `DGR-017..DGR-020`
- **Outcome:** Reconciled legacy truth, canonical metadata, immutable gates, and a controlled whole-model baseline.

## M1 — Protocol and native substrate

- **Stories:** `DGR-021..DGR-033`
- **Outcome:** Versioned gRPC protocol, exact identities/artifacts, pinned upstream, reproducible builds, ShardEngine, and fake worker.

## M2 — Dense vertical proof

- **Stories:** `DGR-034..DGR-043`
- **Outcome:** Dense ranged execution, parity, local state, worker integration, and GGUF inputs to existing routing.

## M3 — DeepSeek V4 Flash alpha

- **Stories:** `DGR-044..DGR-054`
- **Outcome:** Pinned V4 adapter around upstream llama.cpp, real route certification, and pre-locked alpha decision with MTP off.

## M4 — Performance and beta hardening

- **Stories:** `DGR-055..DGR-067`
- **Outcome:** Batching, backpressure, recovery, scale certification, optimization, MTP, and hardware matrix.

## M5 — Release and maintenance

- **Stories:** `DGR-068..DGR-071`
- **Outcome:** Reproducible packages, upstream collaboration, beta decision, and sustainable recertification.

## Release semantics

Alpha is DGR-054 and requires correctness plus the immutable useful-speed contract; MTP remains off. Beta is DGR-070 and requires DGR-066 MTP evidence plus concurrency, recovery, long-context, 10+ scenario, compression/optimization where certified, hardware matrix, and packaging. Failed gates remain failed evidence; they are not relabeled as success.
