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 (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)
