# DGR-041: Register native Shard capabilities without redesigning Meshnet - **Status / triage:** completed; `passes: true` - **Execution mode:** `AFK` - **Milestone:** `M2` - **Dependencies:** `DGR-025`, `DGR-040` - **Blocks (derived):** `DGR-043` - **Labels:** `area:meshnet`, `area:admission`, `type:integration`, `priority:p0`, `ready-for-agent` - **Evidence class:** `model-free` - **Hardware:** `none` - **Model:** `generic` - **Upstream:** `no` ## Objective / description Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/041-register-native-shard-capabilities-without-redesigning-meshnet.md`, and evidence READMEs for dependencies (DGR-025, DGR-040) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Adapt native worker identity and capacity to existing backend-agnostic capability admission. ## Acceptance criteria - [x] Registration carries exact recipe fingerprint, authoritative range, backend, memory/KV capacity, concurrency, and certification status. - [x] Existing tracker, billing, routing, telemetry, and provider semantics remain backend-agnostic. - [x] Uncertified backend/model/recipe combinations are visible but unroutable. - [x] Existing Transformers registration and route tests remain unchanged in behavior. - [x] 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-041/README.md`. Legacy evidence remains provenance only and grants no implementation completion credit.
