+# DGR-039 is blocked: no real dense ranged executor exists
+
+**Date:** 2026-08-01
+
+`DGR-039` remains `passes: false` in the authoritative `prd.json`.
+
+## Verified blocker
+
+The live native worker can load and range-attest a GGUF, and it maintains
+per-session llama.cpp KV bookkeeping.  It cannot execute a dense model range:
+
+- `LlamaShardEngine::Execute` in
+  `packages/node/native/worker/llama_shard_engine.cpp` deliberately does not
+  convert the `TensorBundle` into a llama.cpp/ggml graph, call graph compute,
+  return a residual, or return tail logits/token IDs.  Its only successful
+  effect is advancing `session.past_len` and the local token reservation.
+- `ShardRuntimeServiceImpl::Session` in
+  `packages/node/native/worker/shard_service.cpp` returns the incoming prefill
+  bundle verbatim (`*response.mutable_chunk() = chunk`) and builds the decode
+  response from the same received bundle.  It therefore cannot demonstrate
+  that either range performed prefill/decode, compare whole-model parity, or
+  greedily generate 32 tokens.
+- `tests/test_architecture_boundary.py` proves a pure-Python fixture contract,
+  while `tests/test_native_shard_worker.py` proves an echo seam.  Neither is a
+  real GGUF execution route.  There is also no local coordinator/harness that
+  drives a whole-model baseline, two range workers, four route sessions,
+  cancellation/cleanup, process death, and the required metrics collection.
+
+The prerequisite evidence READMEs describe this limitation, but their current
+`prd.json` completion flags do not alter the live implementation above.
+
+## Required follow-on before this acceptance can run
+
+1. Bind the DGR-035 dense boundary adapter to a native llama.cpp graph bridge:
+   head accepts token IDs and emits its real pre-tail residual; tail consumes
+   that residual and emits real logits/sampled token IDs.  Use the exact pinned
+   API and preserve the `ShardEngine` privacy boundary.
+2. Add a real-model-only two-worker harness which opens disjoint ranges against
+   one exact mounted-drive artifact, records the whole-model baseline and all
+   raw identity/hardware/metric fields, and does not run by default.
+3. Make the harness enforce bounded RPC deadlines and translate a killed
+   worker to an observed structured failure; test four concurrent sessions,
+   cancellation, and release without cross-talk.
+4. Run it on a host with loopback sockets and an explicitly selected GGUF.
+   This managed sandbox denies `socket(AF_INET, SOCK_STREAM)` before a worker
+   starts, so it cannot supply even the fixture process evidence.
+
+No criterion is weakened and no real-model evidence is claimed.

+# DGR-039 evidence — local two-process dense acceptance
+
+**Date:** 2026-08-01  
+**Status:** blocked; `prd.json` remains authoritative and keeps
+`DGR-039.passes` as `false`.
+
+## Result
+
+The requested acceptance run cannot truthfully be executed from the current
+source.  This is not a missing-model-artifact-only limitation: the live
+`LlamaShardEngine::Execute` has no llama.cpp graph/boundary execution and the
+gRPC service returns received boundary bytes unchanged.  Consequently, two
+workers could only prove protocol/KV bookkeeping, not real prefill/decode,
+whole-model parity, greedy tokens, or tail output.
+
+See [BLOCKED.md](BLOCKED.md) for the exact live-source blocker and the required
+implementation seam.
+
+## Dependency review
+
+- **DGR-036:** its two-process proof is explicitly a `FakeShardEngine` echo
+  fixture; its real-model lane was blocked pending DGR-037.
+- **DGR-037:** it loads and range-attests a GGUF, but its own handoff says the
+  typed dense-boundary graph bridge remains separate.
+- **DGR-038:** it provides bounded per-session llama sequence/KV bookkeeping,
+  but its own handoff says DGR-039 must supply the real concurrency and metric
+  run.
+
+The live source confirms those limits: `llama_shard_engine.cpp` increments
+`past_len` without computing a graph, and `shard_service.cpp` echoes both
+prefill/decode bundles.

+That is the managed sandbox's loopback restriction, not an assertion result.

+meet DGR-039's real-model acceptance criteria.

+- No artifact was selected and no raw artifact/split hash, hardware/backend,

+- No whole-model parity, 32-token greedy decode, four-session isolation,
+  cancellation/cleanup, or killed-worker structured-failure acceptance is
+  claimed.
+- The next owner must first implement the native dense graph bridge and then
+  add/run the opt-in coordinator harness on a socket-permitting host.  Keep
+  `DGR-039.passes` false until it has the required real run evidence.
