+# Snapshot Hardware Report Phase 24 Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use
+> superpowers:verification-before-completion before recording the phase result.
+> Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** make current-stack paged-vs-vLLM serving snapshots record the hardware
+class so GB10/workstation Blackwell results are not confused with future
+datacenter-Blackwell parity runs.
+
+**Architecture:** extend the existing current serving snapshot harness with a
+small pre-server hardware report. Keep it additive and outside llama.cpp source:
+no patch-series change, no inference behavior change, and no GPU server launch
+in dry-run mode.
+
+**Tech Stack:** Bash, `nvidia-smi`, DGX GB10.
+
+---
+
+## Task 1: Red Check
+
+- [x] **Step 1: Prove the previous dry-run artifact lacks hardware identity**
+
+  Command:
+
+  ```bash
+  ssh dgx.casa 'test -e ~/bench/phase21_harness_dryrun/20260701_051757/hardware.txt'
+  ```
+
+  Result:
+
+  - exited `1`, confirming the existing harness did not write a hardware report.
+
+## Task 2: Add Hardware Report
+
+- [x] **Step 1: Extend `paged-current-serving-snapshot.sh`**
+
+  File:
+
+  - `backend/cpp/llama-cpp-localai-paged/paged-current-serving-snapshot.sh`
+
+  Behavior:
+
+  - writes `$ART/hardware.txt` immediately after preflight;
+  - records `nvidia-smi -L`;
+  - records GPU name, driver, memory, and compute capability when available;
+  - falls back if `compute_cap` is unavailable in `nvidia-smi`;
+  - classifies hardware as `datacenter_blackwell`, `datacenter_other`,
+    `gb10_or_workstation_blackwell`, or `unknown`;
+  - writes a parity note for the detected hardware class;
+  - runs in `DRY_RUN=1` before the script exits.
+
+## Task 3: Verify
+
+- [x] **Step 1: Local syntax/help checks**
+
+  Commands:
+
+  ```bash
+  bash -n backend/cpp/llama-cpp-localai-paged/paged-current-serving-snapshot.sh
+  backend/cpp/llama-cpp-localai-paged/paged-current-serving-snapshot.sh --help
+  ```
+
+  Result:
+
+  - both passed.
+
+- [x] **Step 2: DGX dry run**
+
+  Command:
+
+  ```bash
+  DRY_RUN=1 ART=~/bench/phase24_hardware_report_dryrun/20260701_052741 \
+    /tmp/paged-current-serving-snapshot.sh
+  ```
+
+  Result:
+
+  - preflight verified `docker=0`, `local_ai_worker=0`, `compute=0`;
+  - no paged or vLLM server launched;
+  - `hardware.txt` was written.
+
+  Artifact:
+
+  - `/home/mudler/bench/phase24_hardware_report_dryrun/20260701_052741`
+
+  Hardware report:
+
+  ```text
+  GPU 0: NVIDIA GB10
+  driver=580.159.03
+  compute_cap=12.1
+  hardware_class=gb10_or_workstation_blackwell
+  ```
+
+## Task 4: Record Result
+
+- [x] **Step 1: Update parity docs**
+
+  Updated files:
+
+  - `backend/cpp/llama-cpp-localai-paged/README.md`
+  - `backend/cpp/llama-cpp-localai-paged/docs/GB10_PARITY_PHASE0_RESULTS.md`
+  - `backend/cpp/llama-cpp-localai-paged/docs/PARITY_HANDOFF.md`
+  - `backend/cpp/llama-cpp-localai-paged/docs/VLLM_PARITY_LEVER_MAP.md`
+
+## Self-Review
+
+- No llama.cpp source behavior changed.
+- The harness remains dry-run safe.
+- Future snapshot artifacts now carry enough hardware identity to separate GB10
+  closure evidence from datacenter-Blackwell parity evidence.
