distributed-gguf-runtime: add CMake skeleton, gRPC harness, split-GGUF provisioning, performance contracts

Browse Source 
DGR-019  Lock alpha/beta performance contracts (evidence + contract framework)
DGR-020  Run controlled whole-model GGUF baseline (benchmark results & contracts)
DGR-024  Real generated-gRPC protocol harness (shard_runtime_server.py + tests)
DGR-026  split-GGUF provisioning outside /home (provision script + manifest + tests)
DGR-028  Numbered patch-stack apply & verify (llama_cpp_dependency.py + UPSTREAM_LOCK.json)
DGR-029  Native CMake skeleton + deterministic CPU lane (UPSTREAM_LOCK.json + cmake gating)

New modules:
  packages/node/meshnet_node/dgr_performance/  — performance contract framework
  packages/node/meshnet_node/split_gguf/        — split-GGUF manifest & provisioning
  scripts/provision_split_gguf.py               — artifact provisioning CLI
  tests/test_dgr_performance_contract.py        — contract validation tests
  tests/test_split_gguf_manifest.py             — manifest tests
  tests/test_split_gguf_provision.py            — provisioning tests

[08:48:13] [INFO] [agent] Everything is consistent and green. All acceptance criteria are satisfied, quality gates pass, and evidence is complete. Per instructions, leaving changes uncommitted for manual review.
[08:48:21] [INFO] [agent] [Edit] /run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.ralph-tui/progress.md edit: " - `tests/test_shard_runtime_harness.py` fails to..." → " - `tests/test_shard_runtime_harness.py` fails to..."
[08:48:30] [INFO] [agent] DGR-019 is complete.
[08:48:30] [INFO] [agent] **Summary:** Locked the alpha/beta performance contract for the DeepSeek V4 Flash distributed GGUF track as versioned, digest-sealed machine-readable data, before any distributed benchmark result exists.
[08:48:30] [INFO] [agent] - New package `packages/node/meshnet_node/dgr_performance/` defines all four required lanes (controlled-safetensors, whole-model-gguf, dense-distributed-gguf, v4-flash-distributed) — the first two reference the pre-existing immutable DGR-001 lock rather than duplicating it; the other two are newly locked with fixed prompts, context/output lengths, sampling, concurrency, hardware, and metrics.
[08:48:30] [INFO] [agent] - Alpha requires correctness plus a `human_approval`-gated useful-speed threshold (not an automatic ratio check); beta adds concurrency/long-context/failure/sustained-throughput. Quantization and 2-4/10+ stage counts are named certification-scenario labels only, enforced by a structural test that greps for hardcoding.
[08:48:30] [INFO] [agent] - 28 new tests in `tests/test_dgr_performance_contract.py`, all passing; `compileall`, `git diff --check`, and `scripts/ralph_prd_schema.py validate` all clean.
[08:48:30] [INFO] [agent] - Also found and fixed a pre-existing, unrelated problem: `prd.json`'s top-level schema/gates/milestones content had been silently dropped by some prior tooling pass (not caused by this story), which was breaking 56 tests — restored it from `HEAD` before building on top, same fix pattern DGR-018 used.
[08:48:30] [INFO] [agent] - Evidence written to `.scratch/distributed-gguf-runtime/evidence/DGR-019/README.md`; `prd.json` marked `passes: true` with `completionNotes`; issue markdown regenerated. All changes left uncommitted for review.

[09:09:19] [INFO] [agent] DGR-024 is complete. Summary:
[09:09:19] [INFO] [agent] The real generated-gRPC protocol harness was already implemented and merged, but marked `passes: false` pending independent review. I performed that review: built a fresh `uv`-managed venv (neither the ambient interpreter nor the existing `.venv-rocm` has `grpc` installed) and reran all 11 harness tests for real — they pass, confirming the direct/opaque-relay byte-identity proof, fail-closed negative paths, and generated-stub-drift check all work as claimed.
[09:09:19] [INFO] [agent] I found one real gap against acceptance criterion 5 ("...wire-frame hashes..."): the prior evidence proved wire fidelity only via byte-equality, with no hash ever recorded. I closed it by adding `requests_sha256`/`responses_sha256` to the server's `WireCapture.to_dict()` and extending the test to assert those server-persisted hashes match independently-computed client-side hashes and are identical between the direct and relay paths. I also recorded SHA-256 identities of the generated protobuf stubs.
[09:09:19] [INFO] [agent] I also fixed a recurrence of the known `prd.json` top-level-field-drop bug (restoring it without touching the already-uncommitted DGR-019/DGR-020 work), flipped `DGR-024.passes` to `true` with `completionNotes`, regenerated the issue markdown, and rewrote the evidence README with exact commands/outputs. All quality gates (11/11 + 108/108 PRD-schema tests, compileall, `git diff --check`) pass.

[09:22:49] [INFO] [agent] `verify` (apply→check reverse leaves pristine) passed cleanly. Now let's confirm the apply step actually leaves a correctly patched tree, and test the native build claim (test-meshnet-range-ownership target).
[09:22:49] [INFO] [agent] [Bash] $ source /run/media/popov/d/DEV/repos/d-popov.com/AI/.venv/bin/activate && python3 scripts/llama_cpp_d...
[09:22:53] [INFO] [agent] Apply succeeds, patched tree matches the recorded `patched_tree` (`c0045714735ae5ee7b7334a480d8ac04e03e1b18` per earlier README). Now let's actually try the native CMake/CTest build to independently verify the previously-unreverified claim.
[09:22:53] [INFO] [agent] [Bash] $ cmake --version 2>&1 | head -1
[09:22:57] [INFO] [agent] cmake isn't available in this environment either, so I can't independently re-verify the native CTest build claim — I'll record that honestly rather than repeat it as fact. Let me reverse the patch to restore the pristine checkout.
[09:22:58] [INFO] [agent] [Bash] $ source /run/media/popov/d/DEV/repos/d-popov.com/AI/.venv/bin/activate && python3 scripts/llama_cpp_d...
[09:23:02] [INFO] [agent] Reverse restores exact pristine pin. Now let's check the fail-closed behaviors — first-incompatible-patch reporting, and the license/control-plane boundary checks — by reading the tests and confirming they exercise these paths.
[09:23:03] [INFO] [agent] [Read] /run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/tests/test_llama_cpp_dependency.py

[09:23:17] [INFO] [agent] This is well-scoped: one concern per patch, chained blob assumptions, and explicit upstream API assumptions. This satisfies the "record upstream file/API assumptions and fail with the first incompatible patch" criterion — I confirmed the mechanism (`_check_assumption_blobs`) runs live during my `apply` test above. All five criteria check out against real code and a real live re-run. Let me also confirm PATCH-STACK.md documents this properly.

[09:23:42] [INFO] [agent] This matches a known gotcha from progress.md: `prd.json` top-level fields (`branchName`, `sourceOfTruth`, `qualityGates`, `metadataSchema`, `milestones`) have been silently stripped, almost certainly by ralph-tui's own read/write round-trip. Per that pattern, I should restore them from HEAD before touching anything else in this file.
[09:23:42] [INFO] [agent] [Bash] $ git diff .scratch/distributed-gguf-runtime/prd.json | tail -220
[09:23:57] [INFO] [agent] This is the previously-documented `prd.json` field-drop bug recurring — but this time `userStories` also has legitimate uncommitted updates from other stories (DGR-019/020/024/026 flipped to `passes: true` with completionNotes). I need to restore only the dropped top-level sections from HEAD while preserving all current `userStories` content, then make my own DGR-028 edit on top.

Now let's update `.ralph-tui/progress.md` per the workflow instructions.

[09:25:42] [INFO] [agent] That's intentionally gitignored (session-local Ralph tooling state), consistent with other runs. Everything checks out.
[09:25:42] [INFO] [agent] ## Summary
[09:25:42] [INFO] [agent] DGR-028's patch-stack implementation was already fully built and committed (`7da90ef`) from a prior session, but `prd.json` still had `passes: false`. Per the mandate to distrust legacy pass states, I independently re-verified it against live source rather than accepting that:
[09:25:42] [INFO] [agent] - Confirmed all five patches' SHA256SUMS, the `UPSTREAM-ASSUMPTIONS.json` blob/API bindings, and control-plane/license boundary checks.
[09:25:42] [INFO] [agent] - Live-ran `verify`/`apply`/`reverse` against the real cached `e920c523...` upstream checkout — apply produced the exact locked patched tree, reverse restored the pristine pin. `tests/test_llama_cpp_dependency.py` (7 passed), `compileall`, and `git diff --check` all clean.
[09:25:42] [INFO] [agent] - Honestly noted the one gap: `cmake` isn't installed in this environment, so the prior session's native CTest claim couldn't be re-executed here (not re-confirmed, not retracted).
[09:25:42] [INFO] [agent] - Found (again) the known `prd.json` top-level-field-drop bug, this time with other stories' legitimate uncommitted `passes`/`completionNotes` updates also in the working tree — did a targeted field-level restore from `HEAD` instead of overwriting the whole file, then set `DGR-028.passes = true` and regenerated its issue Markdown.
[09:25:42] [INFO] [agent] Changed: `evidence/DGR-028/README.md`, `prd.json`, `issues/028-...md`, and `.ralph-tui/progress.md` (gitignored). No source/test edits needed — nothing left uncommitted was reverted, and pre-existing unrelated work (DGR-019/020/026 evidence, split_gguf, dgr_performance) was preserved untouched.

[09:42:03] [INFO] [agent] Everything checks out. All acceptance criteria for DGR-029 are met and verified live:
[09:42:03] [INFO] [agent] **Summary:**
[09:42:03] [INFO] [agent] - Formalized the native CMake skeleton/CPU lane that partially existed but was never proven (DGR-028's `build()`/`smoke()`/`reproduce()` had no cmake in that session and no test coverage).
[09:42:03] [INFO] [agent] - Locked an explicit CPU-only configure (`GGML_CPU=ON`; CUDA/HIP/Vulkan/Metal/BLAS all forced `OFF`) in `UPSTREAM_LOCK.json`, added a `ctest_lane()`/`ctest` CLI command running the deterministic model-free `test-meshnet-range-ownership` fixture via CTest, and fixed `reproduce()` to reverse the patch stack afterward (previously left the cache permanently patched, breaking reuse).
[09:42:03] [INFO] [agent] - Live-verified end-to-end: fresh out-of-tree build (~2m16s) → smoke → CTest 1/1 passed → source restored to the exact pristine pin. Confirmed only CPU `ggml` backend libraries were produced, and confirmed an actionable failure (`cmake is unavailable; set CMAKE...`) when the toolchain is missing.
[09:42:03] [INFO] [agent] - Installed `cmake` via pip into the existing repo-root `.venv` (no system-wide package install) since neither ambient Python nor `.venv-rocm` had it.
[09:42:03] [INFO] [agent] - Added two new pytest tests (117 total pass): one offline shape check, one `cmake`-gated wiring test using a fast synthetic CMake project.
[09:42:03] [INFO] [agent] - Repaired the recurring `prd.json` top-level field-drop bug, marked `DGR-029.passes = true`, regenerated the issue file, and wrote `.scratch/distributed-gguf-runtime/evidence/DGR-029/README.md`.
[09:42:03] [INFO] [agent] Changes are left uncommitted for review, per instructions.

# DGR-019 evidence — lock alpha and beta performance contracts
**Completed:** 2026-07-22
**Branch:** `ralph/distributed-gguf-runtime`
**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
**Dependency:** DGR-017 (`evidence/DGR-017/README.md`) — cleaned backlog reconciled to `origin/master`; no old pass state transferred.
## Objective
Freeze useful-speed, correctness, memory-fit, and stop/go thresholds for the DeepSeek V4 Flash
distributed GGUF track *before* any distributed implementation produces a benchmark result, per
`.scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.md`.
## Pre-existing state found (not caused by this story)
Before any change in this session, `git status` showed `.scratch/distributed-gguf-runtime/prd.json`
already modified in the working tree relative to `HEAD` (commit `47bad0b`), with no corresponding
progress-log entry. Diffing against `HEAD` showed the working copy had **dropped** prd.json's
top-level `sourceOfTruth`, `qualityGates`, `metadataSchema`, `milestones`, and `supersededStories`
objects (replacing them with only a bare `metadata: {"updatedAt": ...}` stamp), while `userStories`
itself was byte-identical to `HEAD`. Running `tests/test_ralph_prd_schema.py` against the
as-found working tree confirmed the damage: 56 of 108 tests failed (every
`test_render_issue_markdown_matches_committed_file[...]` parametrization, since
`quality_gate_bullets`/`authority_disclaimer` fall back to module defaults once `qualityGates`/
`metadataSchema` are absent, which no longer match the committed issue files).
This is the same shape of problem DGR-018's evidence documented and fixed: an abandoned,
unexplained edit that silently dropped the schema/gates/milestone/provenance content this and
future stories depend on, while `scripts/ralph_prd_schema.py validate` did not catch it (those
top-level sections are optional-if-absent by design, so the CLI reported `OK: 55 stories
validated.` even with them missing). The most likely cause is `ralph-tui`'s own read/write of
`prd.json` as its task source, which only round-trips the fields it models
(`name`/`description`/`branchName`/`userStories`) and stamps its own `metadata.updatedAt`,
dropping any project-specific extension fields it doesn't know about.
Per `RALPH-CONTEXT.md`'s instruction to inspect `git status` and preserve unrelated work rather
than build on top of unexplained state, and following the DGR-018 precedent, the dropped fields
were restored verbatim from `HEAD` (`git show HEAD:.scratch/distributed-gguf-runtime/prd.json`)
while keeping the current `userStories` content (identical) and the current `metadata.updatedAt`
stamp. `tests/test_ralph_prd_schema.py` returned to `108 passed` immediately after the restore,
before any DGR-019-specific change was made.
## Changes
### `packages/node/meshnet_node/dgr_performance/` (new package)
- **`data/alpha-beta-contract-v1.json`** — the locked, versioned, machine-readable contract.
`schema_version`/`contract_version`/`contract_id` (`dgr-alpha-beta-performance/v1`), sealed with
a `contract_sha256` digest over its own canonical content (the repository's existing digest
convention, shared with `meshnet_node.glm_alpha.contract`). Contents:
- `prompt_set` — four fixed prompts (`short-instruction`, `code-completion`,
`multi-step-reasoning`, `long-context-fill`) referenced by ID from every lane, so no lane can
quietly drift onto a different workload.
- `sampling` — greedy (`temperature=0`, `top_p=1`, `top_k=1`, `seed=1234`), matching
`meshnet_node.recipe_benchmark.SamplingPolicy` defaults.
- `lanes` — all four lanes named in the acceptance criteria. `controlled-safetensors` and
`whole-model-gguf` are marked `locked_elsewhere: true` and point at the pre-existing immutable
DGR-001 lock (`meshnet_node.performance_contract`, `contract_version=1`,
`ContractThresholds`) rather than re-defining or risking a conflicting duplicate. Only
`dense-distributed-gguf` and `v4-flash-distributed` are newly locked here, each with fixed
`prompt_ids`, `context_tokens`/`output_tokens` (alpha- and beta-scale for the V4 lane),
`concurrency_levels`, `hardware` (named certification-scenario topology, network class, device
class, MTP-off note), and a `metrics` list drawn from the existing
`recipe_benchmark`/`performance_contract`/`route_session_benchmark` metric vocabulary
(`ttft_p50_ms`, `decode_tokens_per_sec`, `seam_bytes`, `seam_latency_ms`, ...).
- `gain_attribution` — two disjoint metric sets, `quantization_model_fit_metrics` and
`runtime_transport_batching_kernel_metrics`, plus the rule that a speed/fit claim must cite
which axis moved it.
- `certification_scenarios` — `quantization` (`Q4_K_M`, `Q8_0`, `bf16-reference`) and
`stage_count` (`2-4-stage`, `10-plus-stage`) as named labels only, with an explicit rule that
no product/runtime code path may hardcode them.
- `alpha` — correctness thresholds (greedy token agreement, mean state cosine similarity,
nonfinite-tensor/fail-closed checks, no dense-attention-fallback credit) plus a `useful_speed`
block whose ratios (`1.25`/`0.75`-class, matching the already-locked DGR-001 25% convention)
carry an explicit `human_approval` sub-block (`required: true`, `approved: false`,
`approved_by: null`, `approved_at: null`). The ratio alone cannot satisfy alpha; DGR-054 must
fill in the approval against real evidence. `mtp.reserved=true`/`enabled_for_alpha=false` per
`RALPH-CONTEXT.md`. `verdicts: ["alpha", "optimize", "stop"]`.
- `beta` — adds exactly `concurrency`, `long_context`, `failure`, `sustained_throughput` axes
(16k-token long-context threshold matching the V4 lane's `beta_context_tokens`, no-silent-KV-
migration and no-synthetic-workers failure rules, 30-minute sustained-throughput floor).
`verdicts: ["beta", "targeted-optimization", "stop-rollback"]`.
- `amendment_policy` — thresholds may not be weakened/moved/reinterpreted after results are
known; a change requires a new `contract_id`/`contract_version` under human review.
- **`contract.py`** — loader/validator mirroring the proven
`meshnet_node.glm_alpha.contract` pattern: `parse_contract` recomputes the canonical-JSON SHA-256
over the document (excluding the digest field) and requires it match both the document's own
declared `contract_sha256` *and* a digest pinned independently in code
(`CONTRACT_V1_SHA256`), so neither an in-place edit nor a resealed mutation can pass silently.
Structural checks enforce all four required lanes, that the two referenced lanes actually
declare `locked_elsewhere`, that the two newly-locked lanes carry full benchmark-plan fields,
that `alpha.verdicts`/`beta.verdicts` are exactly the three-outcome sets the release gates use,
and — the one property with no analogue in `glm_alpha` — that
`alpha.useful_speed.human_approval.required` is `true`. `seal_contract()` is the only supported
way to produce a new digest, kept separate from load-time verification for the same reason
`glm_alpha` keeps it separate.
- **`__init__.py`** — re-exports the public API, documented as the contract DGR-020, DGR-044,
DGR-054, and DGR-070 are judged against.
### `tests/test_dgr_performance_contract.py` (new, 28 tests)
Deterministic, offline, GPU-free, model-download-free. Covers: packaged load and identity; digest
recomputation; all four lanes present; the two referenced lanes point at the real DGR-001 module
and its actual immutable thresholds (`min_decode_speedup == 1.25`, `max_resident_memory_ratio ==
0.75`); the two newly-locked lanes carry complete benchmark plans, fixed context/output/
concurrency; the shared prompt set and every lane's `prompt_ids`/`beta_prompt_ids` are a subset of
it; sampling is greedy; `gain_attribution`'s two metric sets are non-empty and disjoint;
certification-scenario names and rule text; **a structural test that greps every `.py` file under
`packages/node/meshnet_node` (excluding this contract's own module and data file) for the literal
strings `2-4-stage`/`10-plus-stage` and fails if any product module hardcodes them** — the concrete
form of "no product logic may hardcode them"; alpha verdicts/correctness/`human_approval`/MTP-off;
beta verdicts/axes/long-context/failure semantics; digest-mutation rejection (in-place and
resealed); missing-digest rejection; `load_contract` from an explicit path matches the packaged
load; `seal_contract` reproduces the pinned digest; amendment policy text.
### `.scratch/distributed-gguf-runtime/prd.json`
- Restored the top-level `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/
`supersededStories` objects dropped by the pre-existing unrelated edit (see above); kept the
current `metadata.updatedAt` tooling stamp.
- Marked `DGR-019.passes = true` with `completionNotes` summarizing this outcome.
### `.scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.md`
Regenerated via `python scripts/ralph_prd_schema.py render` to reflect `passes: true` (checked
acceptance criteria, "completed" status line, "Verified evidence" handoff line), matching the
convention DGR-017/DGR-018's issue files already use.

This full sweep was launched in the background while `prd.json`/the evidence README below were
still being written, so it raced its own inputs: one of its 7 failures
(`test_ralph_prd_schema.py::test_real_backlog_passed_stories_have_completion_evidence`) was this
story's own `passes=true`/evidence-README edit landing mid-run, not a real defect — re-running
`tests/test_ralph_prd_schema.py` alone afterward, against the finalized tree, gives
`108 passed`. The other 6 failures (`test_billing_ledger.py::
test_tracker_enables_billing_with_default_db`, `test_dynamic_routing.py::
test_admin_can_replace_a_served_model_and_release_it`, `test_dynamic_routing.py::
test_models_list_does_not_duplicate_a_preset_registered_by_hf_repo`, three cache tests in
`test_real_model_backend.py`) are in files this story's `git diff` never touches (`git diff --stat
HEAD -- tests/test_billing_ledger.py tests/test_dynamic_routing.py tests/test_real_model_backend.py`
is empty) and none of them import `dgr_performance`, `performance_contract`, or `glm_alpha`; they
are pre-existing baseline defects, not regressions from this story, in the same spirit as the
known `origin/master` limitations DGR-017's evidence recorded.
## Known limitations
- `tests/test_shard_runtime_harness.py` fails to *collect* in this environment
(`ModuleNotFoundError: No module named 'grpc'`). This is a pre-existing environment gap from
DGR-024's real generated-gRPC protocol harness, not something this story touched or caused; it is
excluded from the sweep above rather than silently masked.
- Alpha's `useful_speed` ratios (`1.25`/`0.75`-class) are proposed thresholds held at the same
margin already locked for the whole-model contract (DGR-001/v1). They are locked numbers, but
`human_approval.required=true` means DGR-054 may not treat them as self-certifying from the
ratio alone — a human must approve the observed ratio against real evidence. This session did
not, and could not, supply that approval: no distributed benchmark evidence exists yet.
- `v4-flash-distributed`'s `reference_baseline` documents that a safetensors DeepSeek V4 Flash
distributed baseline may not yet be pinned (that is DGR-044's job); until then, comparisons must
fall back to `dense-distributed-gguf` runtime/transport overhead as an explicit, stated
limitation rather than a silent substitution.
- This is a specification-materialization story; per the shared quality gates, it is intentionally
left uncommitted for manual review rather than given the "one scoped story commit" other stories
get.
## Dependency handoff
DGR-020 (run the controlled whole-model baseline) consumes the DGR-001 lock referenced — not
redefined — by this contract's `controlled-safetensors`/`whole-model-gguf` lanes.
DGR-044 (pin the DeepSeek V4 Flash target contract) and DGR-054/DGR-070 (enforce the alpha/beta
gates) must load `meshnet_node.dgr_performance.load_contract()` and judge results against its
`dense-distributed-gguf`/`v4-flash-distributed` lanes and `alpha`/`beta` sections without changing
any threshold. DGR-054 specifically must populate `alpha.useful_speed.human_approval`
(`approved`/`approved_by`/`approved_at`) as part of publishing its verdict — a satisfied ratio
without a filled-in approval is not alpha certification. Any amendment must open a new
`contract_id`/`contract_version` under human review per `amendment_policy`; this document and its
digest are not editable in place.

# DGR-020 evidence — run the controlled whole-model GGUF baseline
**Completed:** 2026-07-22
**Branch:** `ralph/distributed-gguf-runtime`
**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
**Dependency:** DGR-019 (`evidence/DGR-019/README.md`) — locked the alpha/beta performance
contract, whose `controlled-safetensors` and `whole-model-gguf` lanes are `locked_elsewhere:
true` and point at the pre-existing immutable DGR-001 lock (`meshnet_node.performance_contract`,
`contract_id: dgr-001-controlled-whole-model-baseline-v1`) rather than redefining it.
## Objective
Per `.scratch/distributed-gguf-runtime/issues/020-run-the-controlled-whole-model-gguf-baseline.md`:
execute the exact locked safetensors and whole-model llama.cpp lanes — with locked prompts,
lengths, sampling, concurrency, hardware, and artifact/runtime identities — and publish a
threshold-based decision, before any distributed-implementation benchmark result can influence
it. Because DGR-019 references DGR-001's lock rather than defining a new one, "the exact DGR-019
safetensors and whole-model llama.cpp benchmark lanes" *is* the DGR-001
`dgr-001-controlled-whole-model-baseline-v1` plan. This story re-executes that exact plan live,
on the current real machine, rather than reusing DGR-001's prior numbers as inherited completion
credit.
## Pre-existing state found (not caused by this story)
Before any change, `git status` showed `.scratch/distributed-gguf-runtime/prd.json` already
modified relative to `HEAD` (`47bad0b`). Diffing against `HEAD` showed the same corruption
DGR-018 and DGR-019 documented: the working copy had dropped the top-level `sourceOfTruth`,
`qualityGates`, `metadataSchema`, `milestones`, and `supersededStories` objects (most likely from
`ralph-tui`'s own read/write of `prd.json`, which round-trips only the fields it models). The only
legitimate `userStories` difference from `HEAD` was DGR-019's own (uncommitted) `passes: true`
edit. Restored the five dropped top-level objects verbatim from `HEAD` while keeping the current
`userStories` (including DGR-019's edit) and `metadata.updatedAt`. `tests/test_ralph_prd_schema.py`
went from 56 failed / 108 passed to 108 passed immediately after the restore, before any
DGR-020-specific change.
## Reproducibility verification before running
Every identity DGR-001/DGR-019 pinned was independently re-checked against the current real
machine before the benchmark ran — nothing was assumed from prior evidence:
| Identity | Pinned (DGR-001) | Measured now | Match |
|---|---|---|---|
| llama.cpp commit | `e920c523e3b8a0163fe498af5bf90df35ff51d25` | `e920c523e3b8a0163fe498af5bf90df35ff51d25` | yes |
| `llama-server` SHA-256 | `fd8fe612970f23e447f2e717cfa51665be06b8d7315ba60556e010f6bca510dd` | same | yes |
| BF16 GGUF artifact SHA-256 | `e842fdc35d7f00fda95a54e1b51731ba1d196aea45065cc9f46925fdc1d6f862` | same | yes |
| Q4_K_M GGUF artifact SHA-256 | `a88e3f570e2efeaf06b50df9859db2c70d8646aa3a2c94a14e14d5797a2921a5` | same | yes |
| Torch / Transformers versions | `2.10.0+rocm7.13.0a20260513` / `5.13.0` | same | yes |
The safetensors snapshot, both GGUF artifacts, the pinned `llama-server` binary, and the pinned
Python runtime were all still present unmodified on `/run/media/popov/DATA/llm/`, so this session
reused them exactly rather than reconverting or requantizing (which would itself have been a
silent redefinition of an immutable artifact identity).
## Real results — fresh run on real hardware
`.scratch/distributed-gguf-runtime/evidence/DGR-020/benchmark-config.json` and
`performance-contract.json` are byte-identical copies of DGR-001's (same `plan_sha256`
`efe24690a9a7164bac6ab3fd0a6b22f078fc08aaefcfb96210ddf154e6050570` and `config_sha256`
`00b2cce3e2f281bdf92fc5304ba5cac915a178ffccd3b9a25995ce39c00b90d3`), so this is the same plan,
not a new one.
```bash

All three recipes completed every request with zero failures, on CPU, `fedora`
`7.0.14-101.fc43.x86_64`, 32 logical CPUs:
| Metric | Transformers BF16 (ref) | llama.cpp BF16 | llama.cpp Q4_K_M | DGR-001 (prior run, same plan) |

| Mean similarity vs reference | — | 0.9471 | 0.456 (advisory) | 0.9471 |
Per-recipe measurements against the reference (`baseline.json`, `contract-evaluation.json`):
- `llama-cpp-near-lossless-quality` (BF16, quality lane): decode speedup **2.02x**, aggregate
throughput speedup (c=4) **4.47x**, resident-memory ratio **0.574x**, TTFT ratio **0.459x** —
but `quality_pass: false` (exact match 0.33 < required 0.90).
- `llama-cpp-quantized-performance-fit` (Q4_K_M, performance-fit lane): decode speedup **4.19x**,
aggregate throughput speedup (c=4) **4.83x**, resident-memory ratio **0.280x**, artifact-size
ratio **0.398x**, TTFT ratio **0.525x**; drift is advisory only for this lane (never read as
quantization/bf16 numerical-equivalence evidence).
The absolute numbers move by ordinary machine-load variance (single-digit-percent) from DGR-001's
prior run of the identical plan; every pass/fail threshold crossing is identical, and the drift
figures (`exact_match_rate=0.3333`, `mean_similarity=0.9471`) are bit-for-bit the same greedy
divergence DGR-001 recorded, on the same three fixed prompts. This is a genuine independent
reproduction, not a copy: `results.json`'s `provenance.run_id`
(`59b12968-c5d0-4391-90f4-0cd2aff77b21`), `started_at`/`completed_at` timestamps, and Ed25519
`signature` are all freshly generated by this session's run, signed with the same DGR-001 evidence
key (`signer_public_key_sha256` `8baca8742d9b3ed0c3fc54929c23f75ec8c1c739900aaf5334780d598ffa84de`,
matching the sole active entry in `../../trusted-evidence-signers.json`).
## Gain attribution — quantization/model-fit versus runtime/transport/kernel
Per DGR-019's `dgr_performance` contract `gain_attribution` rule ("a speed or fit claim must cite
which axis moved it"):
- **Quantization/model-fit metrics** (`resident_memory_ratio`, `artifact_size_ratio`,
`exact_match_rate`, `mean_similarity`): the Q4_K_M recipe's memory win (0.280x) and size win
(0.398x) are attributable to the *weight-format/quantization* change (GGUF Q4_K_M vs Transformers
BF16 safetensors), not to any runtime/kernel change — the BF16 GGUF recipe, which changes runtime
but keeps the same near-lossless bit width, still shows a real (smaller) memory win of 0.574x
purely from the GGUF container/runtime being lighter-weight than the Transformers/PyTorch process,
which separates "quantization" memory savings (BF16→Q4_K_M: 0.574x→0.280x) from "runtime/format"
memory savings (safetensors→BF16 GGUF: 1.0x→0.574x). The quality-lane failure
(`exact_match_rate=0.3333`) is on the *quantization/model-fit* axis by the contract's own metric
list, even though the affected recipe (BF16 GGUF) is near-lossless — i.e. this is evidence of an
unexplained GGUF-runtime/conversion divergence at the same bit width, not a quantization
trade-off, and DGR-001's evidence already recorded that its root cause is undetermined.
- **Runtime/transport/batching/kernel metrics** (`decode_speedup`, `ttft_ratio`,
`aggregate_throughput_speedup`, `prefill_tokens_per_sec`): both GGUF recipes' decode-speed and
prefill-speed wins over the Transformers reference (2.02x/4.19x decode, 1740/1181 tok/s prefill
vs 700 tok/s) are attributable to the *llama.cpp GGML kernel and server runtime*, not to
quantization — the BF16 GGUF recipe reproduces almost the same speedup pattern as Q4_K_M despite
carrying the same bit width as the Transformers reference, so the dominant single-request speed
win here is a runtime/kernel effect, and only the *additional* Q4_K_M-over-BF16-GGUF delta
(102.5→213.1 tok/s decode, ~2.08x) is attributable to quantization on top of that runtime effect.
No distributed-lane (`dense-distributed-gguf`, `v4-flash-distributed`) result exists yet and none
was consulted; this story measures single-node recipe swap only.
## Failed / unavailable lanes
None. All three configured recipes (`transformers-safetensors-reference`,
`llama-cpp-near-lossless-quality`, `llama-cpp-quantized-performance-fit`) completed every request
at both concurrency levels with zero failures; nothing is reported as available-but-degraded or
silently skipped. There is no fourth lane to run here: DGR-019's contract explicitly does not
re-define `controlled-safetensors`/`whole-model-gguf` as separate artifacts from DGR-001's plan, so
running "the exact DGR-019 lanes" is exactly this one three-recipe experiment.
## Decision
`contract-evaluation.json` (evaluated with the unmodified, immutable
`meshnet_node.performance_contract` v1 thresholds — `min_decode_speedup=1.25`,
`max_ttft_ratio=1.25`, `min_aggregate_throughput_speedup=1.25`, `max_resident_memory_ratio=0.75`,
`min_quality_exact_match_rate=0.90`, `min_quality_mean_similarity=0.97`, `max_failure_rate=0.0`)
records:
```text
speed_benefit: true
fit_benefit: true
quality_lane_pass: false
stop_condition_met: true
verdict: stop
```
Mapped to this story's `go` / `optimize baseline` / `stop` vocabulary: **stop**. A meaningful speed
benefit and a meaningful fit benefit were both measured and would ordinarily be sufficient to
`go`/`optimize`, but the immutable v1 stop condition is explicit that a failed near-lossless
quality lane overrides speed/fit benefits ("indicates a broken runtime rather than a quantization
trade-off"). This decision uses only the locked v1 thresholds and this session's freshly measured
metrics; no threshold was changed, and no distributed-implementation result (DGR-024's gRPC
harness or any other distributed-lane evidence) was read or ingested to produce it.
This reproduces DGR-001's original `stop` verdict on the same plan on the same real machine,
confirming that verdict is stable over time and not an artifact of a single run.
## Limitations
- This is a **0.5B CPU baseline** (`Qwen/Qwen2.5-0.5B-Instruct`), the same generic model DGR-001
and DGR-019's `locked_elsewhere` reference use — not DeepSeek V4 Flash. DGR-019's evidence
already recorded that a DeepSeek V4 Flash `controlled-safetensors`/`whole-model-gguf` baseline is
not yet pinned; that is separate future work (see DGR-019's `v4-flash-distributed.reference_
baseline` note), not something this story's acceptance criteria ask it to create — it asks only
to run the exact already-locked lanes, which are this DGR-001 plan.
- The `whole-model-gguf` quality-lane exact-match divergence (0.33 vs 0.90 required) reproduces
identically and remains unexplained; this story does not diagnose it further beyond confirming
it reproduces (DGR-001's `quality-parity-diagnosis.md` documents the CPU-vs-ROCm split already
known).
- Absolute timings are single-developer-machine measurements with ordinary run-to-run variance;
the locked ratios/ratios-vs-threshold crossings are the durable evidence, not the raw absolute
tok/s figures.
- No new GPU (ROCm) diagnostic was re-run in this session — DGR-001's existing GPU diagnostic is
cited as prior evidence only; it uses a distinct signed `run_configured_gpu_diagnostic/v1`
producer that the v1 evaluator does not accept, so it cannot itself change the `stop` verdict
above.
## Files changed
- `.scratch/distributed-gguf-runtime/evidence/DGR-020/benchmark-config.json` (new) — byte-identical
copy of DGR-001's locked plan.
- `.scratch/distributed-gguf-runtime/evidence/DGR-020/performance-contract.json` (new) —
byte-identical copy of DGR-001's immutable v1 thresholds.
- `.scratch/distributed-gguf-runtime/evidence/DGR-020/results.json` / `results.txt` (new) — raw
signed real evidence from this session's fresh run.
- `.scratch/distributed-gguf-runtime/evidence/DGR-020/baseline.json` / `contract-evaluation.json`
(new) — distilled baseline and fail-closed v1 verdict for this session's run.
- `.scratch/distributed-gguf-runtime/evidence/DGR-020/README.md` (new, this file).
- `.scratch/distributed-gguf-runtime/prd.json` — restored the dropped top-level
`sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/`supersededStories` objects (see
above); marked `DGR-020.passes = true` with `completionNotes`.
- `.scratch/distributed-gguf-runtime/issues/020-run-the-controlled-whole-model-gguf-baseline.md` —
regenerated via `python scripts/ralph_prd_schema.py render` to reflect `passes: true`.
No source or test files under `packages/` or `tests/` were changed by this story.

Exit code 0 (no whitespace errors).
## Dependency handoff
DGR-054 (enforce the alpha gate) may cite this evidence when it fills in
`alpha.useful_speed.human_approval` — this is fresh, independently-collected, signed real-hardware
evidence that the `controlled-safetensors`/`whole-model-gguf` v1 contract still holds `stop` on the
current machine, immediately before any distributed-lane result exists, but it is a 0.5B CPU
baseline, not the DeepSeek V4 Flash target; DGR-044 must still pin the V4 Flash reference baseline
separately before DGR-054/DGR-070 can judge `dense-distributed-gguf`/`v4-flash-distributed` against
it. No threshold in either `meshnet_node.performance_contract` or `meshnet_node.dgr_performance`
was changed by this story.

# DGR-026 evidence — provision exact split-GGUF artifacts outside `/home`
**Status:** implemented and verified this session; live re-review, not inherited credit.
**Dependency:** DGR-025 (`evidence/DGR-025/README.md`) — read before changing code.
## Objective
Make exact split-GGUF inputs reproducibly available from mounted-drive
storage, bound by a hashed manifest that fingerprints the source artifact,
tokenizer/revision, and every split file, without embedding a quantization or
split-topology assumption anywhere in product code.
## What was found live (verified, not inherited)
Per RALPH-CONTEXT, legacy pass states were not trusted. No prior split-GGUF
manifest or provisioning module existed:
`grep -rln "provision\|mounted-drive" packages/ scripts/ tests/` found only
`packages/node/meshnet_node/recipe_drivers.py`'s existing
`artifact_storage_root` `/home` check (benchmark config validation, not
provisioning) and the RALPH-CONTEXT/prd.json prose itself. The pre-existing
`packages/node/meshnet_node/downloader.py` is a different mechanism entirely —
it fetches HuggingFace SafeTensors *layer* shards into `~/.cache/meshnet/shards`
(i.e. under `/home` by default) for the existing Tracker route/download flow,
with no manifest binding or split-GGUF concept; it was left untouched because
this story's provisioning target (mounted-drive-only, hash-manifest-bound
split-GGUF files) is a distinct concern from that peer/HF shard cache.
Two existing conventions were read and reused directly rather than
reinvented:
- `packages/node/meshnet_node/glm_alpha/manifest.py` (DGR-017) — the
per-shard identity manifest shape (name/size/sha256/revision, aggregate byte
cross-check) that this story's manifest schema follows for source/split
records.
- `packages/node/meshnet_node/runtime_recipe.py`'s `DerivativeBinding` (DGR-003)
— the half-open (`shard_start`, end-exclusive `shard_end`) range convention
a split is bound to its source under; this story's optional per-split range
fields use the same convention so a route already speaks the same layout
language.
- `packages/node/meshnet_node/recipe_drivers.py`'s `_validate_config` — the
exact `/home` rejection shape (`not root.is_absolute() or root ==
Path("/home") or Path("/home") in root.parents`) this story's
`reject_home_path` mirrors for provisioning destinations.
## What was built (this story's change)
### `packages/node/meshnet_node/split_gguf/` (new package)
- **`manifest.py`** — `SplitArtifactManifest`: binds a `SourceArtifact`
(artifact id, repo, 40-hex pinned revision, sha256, size), a `TokenizerRef`
(repo, 40-hex pinned revision, sha256), a free-form `quantization` string
(a recipe input, not a validated enum), and a tuple of `SplitFile` records —
each with `name`, `size_bytes`, `sha256`, `role`, optional `url`, and an
optional half-open (`shard_start`, `shard_end`) range. `total_bytes` is
cross-checked against the sum of split sizes (rejects a hand-edited "it fits
now" manifest, mirroring DGR-017's aggregate check); duplicate names and
duplicate content hashes are rejected; revisions must be full 40-hex commits
(a branch/tag/short-SHA is refused). Nothing in this module names a
quantization, shard count, or layout — `test_quantization_and_topology_are_manifest_data_not_constants`
parses a single-split, differently-quantized manifest to prove it.
- **`provision.py`** — `provision_split_artifact(manifest, dest_dir, fetch)`:
for each split, reuses an already-correct final file untouched (idempotent
re-run), discards and re-fetches a file with the wrong size/hash rather than
trusting it, stages fetches as `<name>.partial` so an interrupted run
resumes from the exact byte offset already on disk (a stale partial *larger*
than the manifest size is discarded and restarted, never trusted), and
promotes a partial to its final name only once its SHA-256 matches the
manifest exactly — a short, truncated, or hash-mismatched split is deleted
and raises `SplitProvisionError` rather than being silently accepted.
`verify_provisioned_split_artifact` is the standalone completeness/hash
check a downstream loader or a resumed run should call before trusting a
directory. `reject_home_path` is the fail-closed `/home` gate, called by
every entry point (provision, verify) before touching disk, and does not
require the destination to exist yet (provisioning creates it), unlike
`recipe_drivers.py`'s `strict=True` benchmark-root check. Two `SplitFetcher`
implementations are provided: `local_directory_fetcher` (byte-for-byte copy
with seek-based resume from a local directory — used by tests and for
splits already staged/mirrored on another local or mounted path) and
`http_split_fetcher` (Range-header resume over HTTP/HTTPS for real network
provisioning, with a fallback to a full restart if a server ignores
`Range`).
### `scripts/provision_split_gguf.py` (new)
A CLI wrapper: `--manifest`, `--dest`, optional `--source-dir` (uses
`local_directory_fetcher` instead of downloading each split's manifest `url`).
Manually smoke-tested end to end this session (see Commands below), including
a real `/home` destination rejection through the CLI, not just the library.
### Tests (new, deterministic, offline, GPU-free, download-free)
- `tests/test_split_gguf_manifest.py` (19 tests) — resolves source/tokenizer/
splits correctly; quantization/topology are manifest data, not constants
(single-split, differently-quantized manifest parses); digest stability;
rejects: split declaring only one of `shard_start`/`shard_end`, an empty
range, a missing required field, a duplicate split name, two splits sharing
one content hash, an inconsistent aggregate byte total, a shrunk split size,
a truncated SHA-256, a branch-name source/tokenizer revision, an unsupported
schema version, an empty `splits` array.
- `tests/test_split_gguf_provision.py` (12 tests) — covers exactly the four
scenarios the acceptance criteria name:
- **`/home` rejection** — a `/home/...` destination, `/home` itself, and a
nested `/home` subdirectory are refused by both `provision_split_artifact`
and `verify_provisioned_split_artifact`; a mounted-drive-style path is
accepted.
- **Interrupted download → resume** —
`test_an_interrupted_partial_download_resumes_from_its_exact_byte_offset`
plants a half-written `.partial` file, wraps the fetcher to record the
`resume_from_bytes` argument it's actually called with, and asserts
resume starts from the exact prior byte count (not 0) while an
unstarted split still starts from 0; a stale partial larger than the
manifest size is discarded and restarted from scratch.
- **Missing split** — a missing local source file raises
`SplitProvisionError` during provisioning; a split absent from an
already-provisioned destination is caught by
`verify_provisioned_split_artifact`.
- **Hash mismatch** — a same-size-but-wrong-content source file is rejected
(`SplitProvisionError`, and neither the corrupt final file nor its
`.partial` is left on disk); a destination file with the wrong hash (but
right size) is not trusted and is transparently replaced by a correct
re-fetch; a destination corrupted after a prior successful provisioning
run is caught by `verify_provisioned_split_artifact`.
- Also: idempotent no-op re-run over already-complete, correctly-hashed
splits (verified with the source files deleted, proving no re-fetch was
attempted).
## Acceptance criteria → evidence
1. **Exact manifest binding source artifact, tokenizer/revision, every split's
name/size/range-or-role/hash** — `SplitArtifactManifest`/`SourceArtifact`/
`TokenizerRef`/`SplitFile` in `manifest.py`; covered by
`test_split_gguf_manifest.py`.
2. **Resumable, hash-verifying provisioning targeting mounted-drive storage;
refuses `/home` and incomplete/mismatched splits** —
`provision_split_artifact`/`verify_provisioned_split_artifact`/
`reject_home_path` in `provision.py`; covered by
`test_split_gguf_provision.py` and the CLI smoke test below.
3. **Quantization/topology are manifest/recipe inputs, not hardcoded** —
`quantization` is a free-form string; `SplitFile.shard_start`/`shard_end`
are optional per-split fields; no product module names a quant, node
count, or range constant. Verified by
`test_quantization_and_topology_are_manifest_data_not_constants` (a
single-split, differently-quantized manifest parses without any code
change).
4. **Deterministic model-download-free tests covering interrupted resume,
missing split, hash mismatch, `/home` rejection** — see the Tests section
above; all fixtures are in-memory or tiny `tmp_path` files, no network
access anywhere in the suite.
5. **Gates + this handoff** — below.

nothing from it is committed or referenced by the test suite.
Default tests are model-download-free, API-credit-free, and GPU-free; no model
artifact was downloaded and nothing product-relevant was written under
`/home` (the CLI smoke test's `/home` path was rejected before any write).

## Gotcha reproduced (pre-existing, documented pattern)
Before touching anything, `.scratch/distributed-gguf-runtime/prd.json`'s
top-level `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/
`supersededStories`/`branchName` fields were already missing in the working
tree at session start (this is the fourth documented occurrence of the
round-trip-drop bug noted in DGR-018/019/020/025's evidence — `userStories`
itself was unaffected, only these top-level fields). Restored them from
`git show HEAD:.scratch/distributed-gguf-runtime/prd.json` before making any
DGR-026 edit; `scripts/ralph_prd_schema.py validate` reported `OK` both before
and after the restoration, confirming (again) that this validator does not
catch the drop on its own.
## Limitations
- `http_split_fetcher` (the real network-download path) is exercised only by
manual code review and the CLI's argument wiring, not by an automated test —
by design, since the default suite must stay network-free. Its Range-header
resume logic shares the same `provision_split_artifact` byte/hash
verification as the tested `local_directory_fetcher` path, so the
fetcher-specific risk surface is the HTTP interaction itself (server Range
support, redirects, auth), not the resume/verify contract.
- No real DeepSeek V4 Flash split-GGUF manifest exists yet — this story
defines the manifest schema and provisioning tooling; DGR-044/DGR-045
(below) are what will populate a real manifest against the pinned target.
- `python3 -m pytest -q` (unscoped full-repo sweep) was not run this session;
DGR-019/DGR-020/DGR-025's evidence already recorded several pre-existing,
unrelated failures in that sweep (missing optional `zstandard`/
`langchain_openai` dependencies, unrelated billing/dynamic-routing/cache
tests, and `tests/test_shard_runtime_harness.py`'s `grpc` import
requirement). This story's own targeted suites, `test_ralph_prd_schema.py`,
`compileall`, and `git diff --check` are all green as recorded above.
- Tracker routing, load balancing, billing, telemetry, and relay semantics are
untouched; this story adds a new, isolated package and does not modify any
existing runtime/identity module.
## Dependency handoff
- **DGR-044** (DeepSeek V4 Flash target contract): when pinning the real
target's split-GGUF artifact, express it as a
`meshnet_node.split_gguf.manifest.SplitArtifactManifest` — `source.sha256`
is the whole-model artifact digest DGR-003's `ArtifactIdentity.source_digest`
compares against, and each `SplitFile`'s `shard_start`/`shard_end` should
match the exact ranges the route's `ShardIdentity`s claim.
- **DGR-045** (V4 GGUF tensor/layer-ownership inventory): once layer ownership
per split is derived, populate each `SplitFile.role` and
`shard_start`/`shard_end` from that inventory rather than restating them —
this manifest is meant to bind, not redefine, DGR-045's ownership finding.
- Any future story that actually provisions a real split-GGUF artifact onto
mounted-drive storage should call `provision_split_artifact` with
`http_split_fetcher` (or `local_directory_fetcher` if mirroring from another
local/mounted path) and must call `verify_provisioned_split_artifact` before
trusting a directory a prior run may have left partially populated.

## Independent re-verification (2026-07-22, fresh Ralph session)
The prior evidence above was carried over from an earlier session that recorded
a focused native CMake/CTest build (`test-meshnet-range-ownership`) it could
not independently reverify because `build/` was not present at commit time
(see the DGR-028 commit message, `7da90ef`). This session re-ran the
Python/Git-level contract live and end to end, and is explicit about what
could and could not be re-checked:
```text

`cmake` is not installed in this environment (`which cmake` fails), so the
native CMake/CTest build claim from the prior session (`test-meshnet-range-ownership`
1/1 Passed) could **not** be independently re-executed here; it is neither
re-confirmed nor retracted, just carried forward from `7da90ef` without a new
build-verified claim in this session. Everything at the Python/Git contract
level — patch digests, assumption-blob enforcement, apply/reverse against the
real cached upstream checkout, patched-tree identity, and pristine-restore —
was independently re-verified against live source in this fresh session.
## prd.json repair (unrelated to DGR-028 itself)
Before editing `DGR-028.passes`, `prd.json` was found with its top-level
`sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/`supersededStories`
fields silently dropped again (`branchName` was also missing but had already
been restored by a prior in-flight edit) — the same ralph-tui round-trip bug
documented for DGR-019/DGR-020. Unlike those occurrences, `userStories` in the
working tree was *not* unchanged: it already carried legitimate uncommitted
`passes: true`/`completionNotes` updates for DGR-019, DGR-020, DGR-024, and
DGR-026 from other stories' sessions. The missing top-level sections were
restored from `git show HEAD:.scratch/distributed-gguf-runtime/prd.json`
while preserving the current `userStories` array verbatim, then
`DGR-028.passes` was set `true` with `completionNotes` added, and
`.scratch/distributed-gguf-runtime/issues/028-implement-numbered-patch-stack-apply-and-verification.md`
was regenerated via `scripts/ralph_prd_schema.py render` (which only prints;
the caller must redirect it into the issue file — it does not write in
place). `python3 scripts/ralph_prd_schema.py validate` and
`python3 -m pytest -q tests/test_ralph_prd_schema.py` (108 passed) both pass
against the repaired file.

# DGR-029 evidence — native CMake skeleton and deterministic CPU lane
**Status:** implementation complete, live-verified in this session (2026-07-22).
**Authority:** local `prd.json` is authoritative; Gitea is a projection.
**Upstream pin:** `e920c523e3b8a0163fe498af5bf90df35ff51d25` (`llama.cpp`, from `UPSTREAM_LOCK.json`).
## What existed before this session
`scripts/llama_cpp_dependency.py` already had `build()`, `smoke()`, and `reproduce()`
functions and `UPSTREAM_LOCK.json` already had a `build` section (both landed as part
of DGR-028's commit `7da90ef`), but:
- No test in `tests/test_llama_cpp_dependency.py` ever exercised `build`/`smoke`/`reproduce`
— only `fetch`/`apply`/`reverse`/`inspect` had coverage.
- `cmake` was not installed in the DGR-028 session's environment ("`cmake` is not installed
in this environment," per its evidence), so this lane was never actually run end to end;
DGR-028's own live-verified CTest evidence used a one-off manual `cmake`/`ctest` invocation
with `-DLLAMA_BUILD_TESTS=ON` outside this driver, against a build directory that no longer
exists in this session.
- The locked `configure_flags` did not force CPU-only backend options (`GGML_CUDA`/`GGML_HIP`/
`GGML_VULKAN`/`GGML_METAL`/`GGML_BLAS`) — relying on upstream per-platform defaults (which
happen to default OFF on Linux, but are undocumented and platform-dependent), and
`LLAMA_BUILD_TESTS` was `OFF`, so no CTest lane existed at all — only a `--help` smoke check
against the unrelated stock `llama-gguf-hash` tool.
This session found and closed those three gaps rather than re-implementing from scratch.
## What changed in this session
- `packages/node/native/llama/UPSTREAM_LOCK.json`: the `build` section's `configure_flags` now
explicitly force `-DGGML_CPU=ON` and `-DGGML_CUDA=OFF -DGGML_HIP=OFF -DGGML_VULKAN=OFF
-DGGML_METAL=OFF -DGGML_BLAS=OFF`, so the CPU lane can never silently gain a GPU/BLAS backend
from a build machine's ambient toolchain. `-DLLAMA_BUILD_TESTS` flipped `OFF` → `ON` (required
so the `test-meshnet-range-ownership` CTest target exists at all — configuring
`LLAMA_BUILD_TESTS=ON` does not itself build every upstream test, only registers them; the
`native_targets` list still controls what actually gets compiled). Added `native_targets` entry
`test-meshnet-range-ownership` and a new `ctest_regex` field
(`"^test-meshnet-range-ownership$"`) naming the exact deterministic model-free fixture CTest
added by DGR-028's patch 0005.
- `scripts/llama_cpp_dependency.py`: factored `_cmake()`'s override/PATH/venv-sibling resolution
into a shared `_toolchain_binary(name, env_var)` and added `_ctest()` using the same resolution
(`CTEST` env override, PATH, or the sibling of the resolved `cmake` binary's environment). Added
`ctest_lane(build_dir)`, which loads the lock's `ctest_regex` and runs
`ctest --test-dir <build_dir> -R <regex> --output-on-failure`, printing output on success and
raising `DependencyError` (via the existing `_run` wrapper, which already attaches
stdout/stderr detail) on failure. Added a `ctest` CLI subcommand (`--build-dir`). Wired
`reproduce()` to run `fetch → apply → build → smoke → ctest_lane → reverse`, so a full
`reproduce` run leaves the cached upstream checkout pristine afterward (previously `reproduce()`
left the source permanently patched, which would have broken every *subsequent* `reproduce`/
`fetch` call's `require_clean=True` cleanliness check).
- `tests/test_llama_cpp_dependency.py`: added
`test_build_config_locks_an_explicit_cpu_only_deterministic_lane` (offline; asserts the lock's
`configure_flags` are CPU-only and that `ctest_regex`/`native_targets`/`smoke_binary` all agree
with each other and with `patched_paths`) and
`test_ctest_lane_raises_an_actionable_error_for_a_failing_named_test` (gated on `cmake`
availability via a `requires_cmake` marker mirroring `test_native_identity_emission.py`'s
`requires_cc` pattern; builds a tiny synthetic two-test CMake project — not the full llama.cpp
tree, so it runs in about a second — and proves `ctest_lane()` both passes silently on a passing
named test and raises `DependencyError` naming the failing test on a failing one).
## Toolchain note
Neither the ambient system Python nor `.venv-rocm` has `cmake`. This session installed `cmake`
(the PyPI wheel that bundles prebuilt binaries, version 4.4.0) into the pre-existing repo-root
`.venv` used by earlier DGR-024/DGR-026 sessions (`.venv/bin/cmake`, `.venv/bin/ctest`), which was
already on-disk from a prior session but had never had `cmake` installed into it. All commands
below were run with that `.venv/bin` prepended to `PATH`. This is the same "disposable venv for a
lightweight optional dependency" pattern DGR-024 used for `grpc`.
## Verification — full live `reproduce` run (fresh out-of-tree build)

Wall-clock: `real 2m16.227s` (fresh CPU compile of ggml/llama-common/llama plus the
`llama-gguf-hash` example and the `test-meshnet-range-ownership` fixture; no full `llama.cpp`

`reproduce()`'s final `reverse(source)` call restored the exact locked pin/tree — the cached
workspace is reusable for a subsequent `fetch`/`reproduce` without re-cloning.

## Ensuring build success does not advertise capability
- The locked `configure_flags` disable every accelerator backend explicitly
(`GGML_CUDA/HIP/VULKAN/METAL/BLAS=OFF`) rather than relying on per-platform defaults, so a
successful configure/build can only ever mean "the CPU reference backend compiled" — never an
accelerator claim, and never dependent on whether the build host happens to have a GPU SDK
installed.
- `meshnet-build-metadata.json` (written by `build()`) records `model_downloads: false` and
`semantic_certification: false` alongside the exact commit/patch/flag identities — the artifact
itself, not just prose, states this build proves toolchain compilation only.
- The two targets actually compiled are `llama-gguf-hash` (a stock upstream file-hashing utility;
no inference) and `test-meshnet-range-ownership` (a model-free fixture that writes a tiny
synthetic GGUF and asserts range-ownership bookkeeping — no real model, no generation, no
numerical/backend correctness claim). Neither exercises inference, MoE, attention, or any
DeepSeek V4 semantic path.
## Changed files

- `.scratch/distributed-gguf-runtime/evidence/DGR-029/README.md` (new)
## Limitations
- This is a toolchain/compile-and-link gate plus one model-free ownership-bookkeeping fixture —
it proves the CPU lane builds and the DGR-027/DGR-028 patch stack functions structurally on
CPU. It proves nothing about real-model correctness, memory-fit, performance, or any
backend/model/recipe certification; `stock_glm_limitations` in `UPSTREAM_LOCK.json` and DGR-028's
own limitations continue to apply unchanged.
- `cmake`/`ctest` are not installed system-wide or in `.venv-rocm` in this environment; they were
installed only into the pre-existing repo-root `.venv` for this session's verification (and for
the new gated pytest test, which is skipped in any environment lacking `cmake`). A future session
without that `.venv` (or without re-installing `cmake` into it) will see the same "cmake is
unavailable" actionable failure demonstrated above, not a silent pass.
- Only the two named targets are compiled (`llama-gguf-hash`, `test-meshnet-range-ownership`); a
broad `cmake --build ... --target test` / full upstream test suite is out of scope here, exactly
as DGR-028 recorded ("not presented as a full-suite gate").
- CUDA/ROCm/Vulkan/Metal compile lanes remain unimplemented; this story only establishes the CPU
lane "before accelerator matrix work," per its objective. Those lanes are separate future work.
## Dependency handoff
DGR-030 and DGR-034 (this story's declared blockers) may rely on: an out-of-tree, CPU-only,
explicit-backend-flag native build (`scripts/llama_cpp_dependency.py build`/`reproduce`) that
compiles the exact DGR-027/DGR-028 patched pin and runs a real CTest lane
(`test-meshnet-range-ownership`) proving the patch stack's range-ownership bookkeeping compiles
and passes on CPU. Any accelerator (CUDA/ROCm/Vulkan/Metal) lane, any real-model load, and any
backend/model/recipe capability certification remain unimplemented and must not be assumed from
this story's green build alone.

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)."

"""The locked DGR-019 alpha/beta performance contract.
Four benchmark lanes feed the DeepSeek V4 Flash release gates: controlled
safetensors, whole-model GGUF, dense distributed GGUF, and V4 Flash
distributed. The first two are already locked by DGR-001
(:mod:`meshnet_node.performance_contract`); this module locks the other two,
plus the alpha (DGR-054) and beta (DGR-070) gate thresholds that read them
back.
The contract is written down *before* any distributed implementation
produces a number (DGR-019), so ``contract_sha256`` is verified the same way
:mod:`meshnet_node.glm_alpha.contract` verifies its own alpha contract: the
document's canonical content is re-hashed on every load and compared against
a digest pinned independently in code. A hand-edited "the threshold was
always 5%" mutation is rejected, not silently trusted. An amendment requires
a new ``contract_id``/``contract_version`` under human review; the superseded
contract is retained.
Alpha's useful-speed threshold carries one additional property no other
threshold here has: ``human_approval``. The numeric ratios are locked now,
but DGR-054 (the alpha gate) may not treat useful-speed as satisfied on the
ratio alone — a human must approve the observed ratio against real evidence.
That is a property of *how the threshold may be used*, not a weaker
threshold, and it is asserted structurally by :func:`parse_contract`.

"""Exact split-GGUF artifact manifest (DGR-026).
A split-GGUF artifact is only as trustworthy as its binding to the whole-model
artifact it was cut from. This module defines the manifest that makes a set of
split files an *exact*, checkable artifact rather than a pile of files someone
happened to name plausibly: it pins the source artifact's own content hash, the
tokenizer/revision the splits were tokenized against, and — per split — the
exact file name, size, cryptographic hash, and its range/role within the
source.
Quantization and split topology (how many splits, which layers each one
covers) are recipe inputs recorded on the manifest, never constants in this
module. A manifest with two splits and one with twenty are both valid; nothing
here assumes a stage count or a fixed layer range. Provisioning
(:mod:`meshnet_node.split_gguf.provision`) consumes whatever this manifest
declares.
This module mirrors two existing conventions rather than inventing new ones:
the DGR-017 pinned-shard manifest shape (`meshnet_node.glm_alpha.manifest`) for
per-file identity records, and the DGR-003 `DerivativeBinding` range/source
convention (`meshnet_node.runtime_recipe`) for binding a split to its source by
digest and half-open layer range.

continuing from it — and a partial is promoted to its final name only after its
