Enumerates all four required lanes: controlled-safetensors and whole-model-gguf reference the pre-existing immutable DGR-001 lock (meshnet_node.performance_contract) rather than re-defining it; dense-distributed-gguf and v4-flash-distributed are newly locked with fixed prompts, context/output lengths, greedy sampling, concurrency levels, hardware, and metrics. Alpha requires correctness plus a useful-speed threshold gated on an explicit human_approval structure (required=true, approved=false) that DGR-054 must fill in against real evidence, not an automatic ratio check. Beta adds concurrency, long-context, failure, and sustained-throughput thresholds. Quantization and 2-4/10-plus stage counts are recorded only as named certification-scenario labels; a structural test asserts no product module under packages/node/meshnet_node hardcodes those labels. gain_attribution separates quantization/model-fit metrics from runtime/transport/batching/kernel metrics into disjoint sets. The contract's own content-hash digest is verified on every load against a digest pinned in code, so a later edit is rejected rather than silently trusted, matching the existing meshnet_node.glm_alpha.contract precedent. Also restored .scratch/distributed-gguf-runtime/prd.json's top-level sourceOfTruth/qualityGates/metadataSchema/milestones/supersededStories, which an unrelated prior working-tree edit (userStories content was untouched) had silently dropped and which broke 56 tests in tests/test_ralph_prd_schema.py before this session started."

Ran the canonical opt-in local-real benchmark (meshnet_node.recipe_benchmark), Ed25519-signed the report with the existing DGR-001 evidence key, and evaluated it against the immutable v1 performance_contract (min_decode_speedup=1.25, max_resident_memory_ratio=0.75, min_quality_exact_match_rate=0.90, ...). Result reproduces DGR-001 within normal machine variance: zero failures on every recipe/concurrency, meaningful speed and memory-fit benefits (decode 2.02x-4.19x, aggregate throughput 4.47x-4.83x, resident memory 0.28x-0.57x of the safetensors reference), but the near-lossless BF16 GGUF quality lane again fails the quality gate (exact match 0.33 vs required >=0.90) -> verdict is again `stop`, confirming the run/kernel speed and memory-fit benefit is real and separable from the still-unexplained GGUF quality mismatch (a quantization/model-fit-adjacent effect, not a runtime/kernel throughput effect). No distributed implementation result was consulted or ingested. Fixed a recurrence of the known prd.json top-level-field-drop bug (sourceOfTruth/qualityGates/metadataSchema/milestones/supersededStories were stripped again before this session, restored verbatim from HEAD)."
