 ## Overview
 
-This project manages deployment scripts for two LLM inference servers. Dankclaw runs a llama.cpp service for Qwen3.8-27B (unsloth UD-Q8_K_XL) with llama.cpp's `--spec-default` (ngram-mod, no draft model, Vulkan0 backend, 2 parallel slots, port 7770). Dankclaw's NPU endpoint (FastFlowLM, `frank-default-small`, port 52625) serves Qwen3.6-35B-A3B as registry tag `qwen3.6-moe:35b-a3b` at 262144 ctx (swapped in 2026-08-16; the old llama.cpp 35B service on Dankserver is stopped). See [docs/deployment.md](docs/deployment.md) for the full deployment and update process, and [docs/qwen3.8-spec-matrix.md](docs/qwen3.8-spec-matrix.md) for the spec decision (--spec-default + Vulkan0, 2026-08-15; DSpark retired same day for a ROCm parallel crash; DFlash retired earlier for premature EOS).

+Podman app stack on the same hosts (OpenWebUI, Gitea, observability). Its
+OpenWebUI consumes the `:7770` endpoint; its Gitea instance hosts this

+## Production state (promoted 2026-08-16)
+
+This split is the production `frank-default-large` service (renamed from
+`frank-pp-head`, commit `48142f5`). Current state, verified against the
+live journal (2026-08-16, 15:03 load):
+
+- Split `0.40,0.60` (not the test-day `1,1`): 40% of the layers on the
+  3090 — its maximum under the 2x200700 f16 KV budget — 60% on the iGPU.
+- Pool `401400`, `PARALLEL=2`, live `n_ctx_slot = 200704`.
+- MTP enabled: `--spec-type draft-mtp --spec-draft-n-max 4` + ngram-mod
+  fallback (48/64/24). Journal acceptance: MTP mean len 3.00
+  (per-position 0.730/0.541/0.411/0.323).
+- Head GPU side: **ROCm0** (no `--device` flag; HIP registers before
+  Vulkan). KV at load: 15680 MiB ROCm0 + 9408 MiB RPC0.
+- Unit `frank-default-large.service`, launched through
+  `serve-pp-head.sh` + `frank-default-large.env`.
+
+Open questions from the test day, resolved:
+
+1. MTP (in the last layer group, iGPU side) drafts cleanly across the RPC
+   boundary — see the acceptance figures above.
+2. Two parallel slots hold under production load: 150k-token prompts
+   prefill and generate, slots turn over every few minutes, no RPC
+   faults observed.
+3. Long prompts (~160k tokens) prefill on the ROCm0 side with no
+   RPC-boundary anomaly in production traffic.
