DGR-034: Implement dense-Llama range-aware GGUF ownership

Status / triage: specification only; ready-for-agent; passes: false
Execution mode: AFK
Milestone: M2
Dependencies: DGR-028, DGR-029, DGR-031
Blocks (derived): DGR-035, DGR-037, DGR-051
Labels: area:llama, area:weights, type:runtime, priority:p0, ready-for-agent
Evidence class: real-model
Hardware: optional
Model: dense-llama
Upstream: yes

Objective / description

Fresh Ralph session: read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md, source issue .scratch/distributed-gguf-runtime/issues/034-implement-dense-llama-range-aware-gguf-ownership.md, and evidence READMEs for dependencies (DGR-028, DGR-029, DGR-031) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Load only the dense-Llama tensors owned by a shard range.

Acceptance criteria

Load only blk.N.* tensors in the assigned range, embeddings only at the head, and norm/output or tied output only at the tail.
Derive authoritative range and endpoint ownership from the loaded engine state.
Reject invalid/gapped/out-of-model ranges and unexpected required tensors.
Real-model evidence shows mapped/resident memory scales with owned tensors rather than full artifact size.
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.

Evidence handoff

Write and verify .scratch/distributed-gguf-runtime/evidence/DGR-034/README.md. Until every criterion and applicable gate has real evidence, this story remains passes: false. Legacy evidence is provenance only, not completion credit.
