# KHIPU-R2

Adapters are on this repo. Abstain is MEASURED 3/6, not a pass. Not publication-eligible.

QLoRA adapter on disclosed [`Qwen/Qwen2.5-1.5B-Instruct`](https://huggingface.co/Qwen/Qwen2.5-1.5B-Instruct) (runtime `unsloth/Qwen2.5-1.5B-Instruct-bnb-4bit`). Proposal-only brain navigator / abstain retrain. Doctrine v11 LOCKED. Λ = Conjecture 1 (advisory, never a theorem).

## Evaluation (MEASURED this job)

Method: in-process Unsloth generate, scoring ported from `eval_khipu.py`, temperature 0, held-out never in gradients. Host job worker. Date 2026-08-28 17:20 UTC. File: `eval_measured.json`.

| split | k/n | what-NOT |
|---|---|---|
| plan-valid | **11 / 11** | not a public leaderboard |
| grounding (`eval.jsonl` navigate) | **5 / 5** | n=5 |
| abstain (`adversarial.jsonl`) | **3 / 6** | not 5/5, not 6/6 |
| hallucinated citations | **0** | this job only |

Prior published original `SZL-Khipu-1.5B` MEASURED abstain was **2/6**. This run is **3/6**. Small n. Do not derive a world-rank score from k/n on n=11.

## Training (MEASURED / REPORTED)

- Unsloth QLoRA, seed 11, lr 2e-4, LoRA r=32 α=64, 45 epochs
- Train: 15 navigate + 8 abstain rows × oversample 4 (in-memory 32)
- Held-out: 5 + 6, `held_out_in_gradients: false`
- `training_loss` MEASURED `0.017188…` is a train metric, not an eval
- adapter sha256 `e44d53f29f2d443598e06d6c0441557fd3a5010888c7aa97b56ec3c0e050d349`

## What this is NOT

- Not a replacement for `SZL-Khipu-1.5B`
- Not Chaski (Qwen3.5 lock)
- Not an autonomous agent
- Not a GGUF (A11OY-MINI stays ROADMAP)

## Load
