## Steps

1. Read OpenMDW-1.1 on the base model card/LICENSE. Accept constraints before redistribute.
2. Build engine per `SPARK.md` (CUDA `121` → `121a`, `llama-server`).
3. Record `git rev-parse HEAD` of the engine tree into `results/engine_sha.txt`.
4. Download official GGUF (not a DIY re-quant unless you will measure a real delta):

```bash
huggingface-cli download poolside/Laguna-S-2.1-GGUF \
  laguna-s-2.1-Q4_K_M.gguf \
  --revision fc4e481289523cf7d0df668da6d1d391616141ca \
  --local-dir ~/models/laguna-s-2.1
sha256sum -c SHA256SUMS
```

5. Serve (`SPARK.md`), confirm `curl /v1/models` → 200.
6. `llama-bench` @ prompt 2048 and 8192; save stdout to `results/llama_bench_q4km.txt`.
7. `python scripts/bench_server.py --ctx-mark 2k --ctx-mark 8k`.
8. `python eval/agent_smoke/run_smoke.py --out results/smoke_q4km.json`.
9. Populate the tables in `SPARK.md` from those files only — never invent.
10. Publish pack (docs + results + scripts). **Host GGUF binary only if you have a measured unique artifact**; otherwise ship digests + download commands (S5).

## Personal HF publish surface

- User: `hizrianraz` (personal)
- Repo id: `hizrianraz/laguna-s-2.1-spark`
- Card framing: personal measurements only; no org product claims

## DIY quant policy

Only if:

1. Official/Unsloth GGUF cannot load or is >10% worse on agent_smoke pass rate or tg tok/s at same ctx, **and**
2. You publish method + imatrix/source commit + full sha256 + smoke numbers

Otherwise: official GGUF + Spark delta docs only.
