# Yuanl-27B v59-long (LoRA adapter)

LoRA adapter (r=64, alpha=128) in the Yuanl-27B cybersecurity/agentic lineage.

- **Architecture base**: `Qwen3.6-27B` (qwen3_5, with native MTP `nextn` heads in the
  full upstream checkpoint).
- **Lineage**: trained on the SFT-merged base of the v5-x → v5-9-sft chain
  (`merged_v6_1_base`), then long-context (128K) continue-train. Held-out eval
  **7/12**; with a task-completion-discipline system prompt it reaches **9/12**.
- **Targets**: `q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj`
  (language-model layers only; never touches `nextn.*` / `visual.*`).

> Note: this adapter's true training base is the private SFT-merged `merged_v6_1_base`,
> not raw `unsloth/Qwen3.6-27B`. The `base_model` field above points at the public
> architecture base for reference; applying this adapter directly on the raw base
> reproduces only the final delta, not the full v5-x SFT chain.
