+# darkscarlett-charrp-reasoning — Dark-Scarlett char-rp-reasoning seat (ana-ml2 GPU1)
+
+The **thinking** RP reasoning seat. Serves the LiteLLM `char-rp-reasoning` alias.
+
+- **Model:** `Dark-Scarlett-v1.0-27B-NVFP4A16-wrapper` (ReadyArt Dark-Scarlett-v1.0-27B, Qwen3.6-27B base).
+- **Host/GPU:** ana-ml2, GPU1 (co-located with the utility model cluster).
+- **Port:** :8018 → LiteLLM `char-rp-reasoning`.
+- **Context:** 256K (`--max-model-len 262144`). Qwen3.6 hybrid GatedDeltaNet linear-attention → KV-cheap, full 256K easily.
+- **Thinking:** default on (`--reasoning-parser qwen3`; reasoning lands in the `reasoning` field). ⚠ Consumers need a generous `max_tokens` or the reasoning eats the whole budget (empty content, `finish: length`).
+- **Tuning:** `.env` — `DS_GPU_MEM_UTIL=0.44`, `DS_MAX_MODEL_LEN=262144`, `DS_GPU_ID=1`.
+
+## Quant note (the wrapper recipe)
+
+Quantized with **llm-compressor NVFP4A16 loaded via the `Qwen3_5ForConditionalGeneration`
+wrapper class** — an `AutoModelForCausalLM` save produces a flat `Qwen3_5TextConfig` that **both
+vLLM and SGLang reject**; loading the wrapper keeps the config they accept (verified: SGLang errors
+`Qwen3_5ForCausalLM has no SGLang implementation`). ModelOpt was blocked by a modelopt↔transformers
+version deadlock for Qwen3.6. **MTP was dropped by the quant loader → deferred → no `--speculative-config`**
+(spec-decode is net-negative at RP temps anyway). Pipeline: `ana-ml2:/tank/aimodels/darkscarlett-nvfp4-work/`.
+
+Replaces the retired **heretic2-charrp-reasoning** (DavidAU Qwen3.6-27B-Heretic2 modelopt NVFP4+MTP) seat.

+# meromero-charrp — MeroMero-v2 char-rp prose seat (ana-ml2 GPU0)
+
+The **non-thinking, multimodal** RP prose seat. Serves the LiteLLM `char-rp` alias.
+
+- **Model:** `G4-MeroMero-v2-31B-NVFP4A16` (Gemma-4-31B, home-quantized weight-only NVFP4A16).
+- **Host/GPU:** ana-ml2, GPU0 (co-located with `gen` / vllm-aeon-gen).
+- **Port:** :8016 → LiteLLM `char-rp`.
+- **Context:** 256K (`--max-model-len 262144`). Gemma-4 uses sliding-window attention → KV-efficient, ~2× concurrency at full context.
+- **Vision:** enabled (image + text). `preprocessor_config.json` was materialized from the model's own `processor_config.json` (`Gemma4ImageProcessor`); audio is config-declared but weightless.
+- **Tuning:** `.env` — `MEROMERO_GPU_MEM_UTIL=0.52` (leaves ~4.6 GB GPU0 headroom), `MEROMERO_MAX_MODEL_LEN=262144`, `MEROMERO_GPU_ID=0`.
+
+Replaces the retired **char-rp-gguf** (Magidonia-24B GGUF / llama.cpp) seat. The quant pipeline
+lives in `ana-ml2:/tank/aimodels/meromero-v2-nvfp4-work/`.
