[Bash] $ print('OK', b.BOUNDARY_SCHEMA_VERSION, sorted({v.adapter for v in b._CERTIFIED_ARCHITECTURES.values(... All acceptance criteria are met. Summary of what I did for **DGR-006 — Architecture-defined boundary input/output**: ## Implementation **`packages/node/meshnet_node/boundary_adapter.py`** (new) — the boundary contract: - **Fail-closed certification** — `certified_architecture()` maps only dense-Llama spellings (`dense-llama`/`llama`/`LlamaForCausalLM`/...) to an adapter; everything else (Qwen3, Mixtral, gpt2, empty/None) raises `UncertifiedArchitectureError`. - **`BoundaryAdapter`** drives a duck-typed `ShardComputation` and enforces per-role rules: head embeds token IDs (refuses a bundle); middle/tail bypass embedding (refuse token IDs); non-tail emits the **unnormalized** residual with all position rows (no final norm, no LM head, no pruning); tail normalizes → LM head → prunes to last row → samples via an explicit `SamplingContract` (greedy). - **`BoundaryBundle`** — versioned named-tensor bundle carrying the residual + positions + seam `next_layer`, with `pack()`/`unpack()` for disjoint-process round-trip and `named_tensor_fields()` mapping onto the DGR-002 `NamedTensor` shape. **`tests/test_boundary_adapter.py`** (new) — a pure-numpy dense-Llama reference (RMSNorm + RoPE + SwiGLU) satisfying the same protocol; 22 tests proving whole-model vs **two-range and three-range** prefill + greedy-decode parity (identical greedy tokens, logits `atol=1e-6`), plus every contract/fail-closed path. ## Verification (real results) - Targeted: **22 passed** - `compileall`: exit 0 · `git diff --check`: clean - Full suite: `20 failed, 715 passed, 13 skipped, 12 errors` — **clean-tree reproduction** (files moved aside) gives `693 passed` with a **byte-identical** failure/error set, proving DGR-006 introduced zero failures. The pre-existing failures (protobuf gencode mismatch + tracker/routing/optional-dep) are recorded in `results.json`. torch/transformers aren't installed in the default venv, so the numpy reference is the only deterministic, GPU-free, download-free way to prove parity — the identical protocol will be satisfied by the C++ worker (DGR-008). Native C++ / llama.cpp patch gates are N/A (no native code touched), documented in evidence. Evidence written to `.scratch/distributed-gguf-runtime/evidence/DGR-006/` (README + commands.txt + results.json); progress log and issue `Status: done` updated. Pre-existing working-tree changes preserved; no commits created. COMPLETE
