DGR-021: Define the versioned named-tensor stream envelope

Status / triage: completed; passes: true
Execution mode: AFK
Milestone: M1
Dependencies: DGR-018
Blocks (derived): DGR-022, DGR-023, DGR-025, DGR-031, DGR-035, DGR-046
Labels: area:protocol, type:infrastructure, 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/021-define-the-versioned-named-tensor-stream-envelope.md, and evidence READMEs for dependencies (DGR-018) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Establish the backend-neutral protobuf envelope used by direct and relayed Shard activation traffic.

Acceptance criteria

Define schema version, request/work ID, route session/epoch, shard range/effective start, phase, position, and idempotency step.
Define named tensors with shape, dtype, byte order, bounded fragments, compression identity, and checksum.
Reserve extensible fields for token-ID sidebands, architecture state, recurrent state, and MTP without claiming implementations.
Add deterministic serialization, fragmentation, checksum, unknown-field, and size-limit tests.
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

Verified evidence: .scratch/distributed-gguf-runtime/evidence/DGR-021/README.md. Legacy evidence remains provenance only and grants no implementation completion credit.
