# DGR-028: Implement numbered patch-stack apply and verification
|
|
|
|
- **Status / triage:** completed; `passes: true`
|
|
- **Execution mode:** `AFK`
|
|
- **Milestone:** `M1`
|
|
- **Dependencies:** `DGR-027`
|
|
- **Blocks (derived):** `DGR-029`, `DGR-034`, `DGR-069`
|
|
- **Labels:** `area:upstream`, `area:patches`, `type:tooling`, `priority:p0`, `ready-for-agent`
|
|
- **Evidence class:** `model-free`
|
|
- **Hardware:** `none`
|
|
- **Model:** `generic`
|
|
- **Upstream:** `yes`
|

## Objective / description
|
|
|
|
Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/028-implement-numbered-patch-stack-apply-and-verification.md`, and evidence READMEs for dependencies (DGR-027) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Maintain a minimal auditable llama.cpp delta with one numbered patch per concern.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [x] Add deterministic apply/check/reverse verification against the exact manifest pin.
|
|
- [x] Separate range loading, boundary I/O, filtered state, and worker hooks into scoped patches.
|
|
- [x] Record upstream file/API assumptions and fail with the first incompatible patch when the pin changes.
|
|
- [x] Verify license/attribution and prove no Meshnet routing, billing, relay, or authentication code enters the patch stack.
|
|
- [x] 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.
|
|
- Native changes pass focused out-of-tree CMake build and CTest; patch changes verify clean apply/check/reverse against the exact llama.cpp pin.
|
|
- Runs are opt-in and record exact artifact/split hashes, runtime/upstream pin, backend/driver, hardware, network, commands, and raw metrics. Model artifacts use configured mounted-drive storage and never `/home`.
|
|
- Preserve existing Transformers behavior and backend-agnostic Tracker routing/load balancing/billing/relay semantics unless an explicit versioned contract says otherwise. One scoped story commit is expected during execution, but this specification-materialization change is not committed.
|
|
|
|
## Evidence handoff
|
|
|
|
Verified evidence: `.scratch/distributed-gguf-runtime/evidence/DGR-028/README.md`. Legacy evidence remains provenance only and grants no implementation completion credit.
