docs: llama.cpp stack at production state (2026-08-16) + sibling-project links

- spec matrix: new 'Production state' section — PP head (RPC0+ROCm0,
  split 0.40/0.60), pool 401400 / n_ctx_slot 200704 live, MTP n_max 4
  over ngram-mod fallback (journal acceptance stats), f16 KV.
  2026-08-15 standalone state marked superseded (Vulkan0 verdict was
  standalone-only; PP head runs ROCm0 by default).
- deployment.md: fix frank-default-large section (MTP not 'no draft',
  ROCm0 not Vulkan0, 200704/slot not 262144, f16 not q8_0 KV,
  serve-pp-head.sh not serve-llama-frank-large.sh).
- PP deployment doc: production-state section; test-day open questions
  resolved with journal evidence.
- index.md: NPU line now qwen3.6-moe:35b-a3b @262k ctx; Sibling
  projects section -> serverAppConfigs.
- AGENTS.md: overview reflects PP+MTP reality; sibling pointer.

 ### Dankclaw — frank-default-large
 
-The active service on Dankclaw runs llama.cpp serving the unsloth
-Qwen3.8-27B `UD-Q8_K_XL` model under the alias `frank-default-large` on port
-7770. It uses llama.cpp's **`--spec-default`** preset (ngram-mod, no draft
-model) for speculative decoding on the **Vulkan0** backend, with **2
-parallel slots** at 262144 context each, KV cache `q8_0` K / `q8_0` V on
-GPU, full layer offload (`--gpu-layers all`, `--fit off`), and batch 8192 /
-ubatch 256. The unit file is `scripts/frank-default-large.service`. It
-launches through `scripts/serve-llama-frank-large.sh`, which reads tunables
-from `scripts/frank-default-large.env`.
+The active service on Dankclaw is the llama.cpp **pipeline-parallel
+head**. It serves the unsloth Qwen3.8-27B `UD-Q8_K_XL` model under the
+alias `frank-default-large` on port 7770. The head splits the tensors
+`0.40,0.60` to the `ggml-rpc` worker on Dankserver (RTX 3090, port 50052).
+Speculative decoding runs **MTP** (bundled head, `--spec-draft-n-max 4`)
+with the `--spec-default` ngram-mod fallback (48/64/24). The head GPU side
+runs **ROCm0** (no `--device` flag; default device selection puts RPC
+first and picks ROCm for the iGPU). **2 parallel slots** at 200704 context
+each (pool 401400), KV cache `f16` K / `f16` V, full layer offload
+(`--gpu-layers all`, `--fit off`), batch 8192 / ubatch 256, `--direct-io`.
+The unit file is `scripts/frank-default-large.service`. It launches through
+`scripts/serve-pp-head.sh`, which reads tunables from
+`scripts/frank-default-large.env`.
+
+> Note: 2026-08-16 — the pipeline-parallel split was promoted to
+> production as `frank-default-large` (renamed from `frank-pp-head`);
+> the standalone single-node service retired. MTP was re-enabled at
+> `n_max 4` over the ngram-mod fallback. The pool shrank from 524288 to
+> 401400 (2 slots x 200700) to fit the split KV budget. See
+> [[Pipeline Parallelism/Qwen3.8 PP Deployment]] for the runbook.
 
 > Note: 2026-08-15 — the spec went DSpark (crashed under two concurrent 16k
 > prompts on ROCm, `ROCm error: an illegal memory access`, status 6/ABRT) →
