blessed_run_2 — P7 step-24 (Pareto-best loracle ckpt)

The current best loracle checkpoint as of 2026-04-26. Online Dr. GRPO checkpoint at cycle 24 of the drgrpo_p7_v4_lr1e5_b16k16 run.

This is the balanced ckpt: AB / Trig / OOD all near peak. The cycle-29 final crashed Trig from 60→35, so step-24 wins on the Pareto frontier.

Eval Results (Sonnet 4.6 judge, greedy sampling, max_new_tokens=1024)

Eval Set	Any-Match	Rollout-Mean
AuditBench (56 organisms × 3 prompts × 2 rollouts)	78.6%	56.0%
Trigger Recovery (heldout IA) (20 backdoors × 4 rollouts)	60.0%	30.0%
OOD models v3 (22 organisms × 4 prompts × 2 rollouts)	45.5%	27.4%

Beats P5 SOTA (ceselder/blessed_run: AB 76.8 / 55.7) on both AuditBench metrics, and adds substantial Trigger Recovery + OOD generalization.

Training Recipe

• Base: Qwen/Qwen3-14B
• Init: SFT warmstart (sft_warmstart_posttrain_v5/step_0000110) → init from pretrain ceselder/loracle-pretrain-v7-sweep-A-oneq-final-step3120
• RL algorithm: Online Dr. GRPO with asymmetric clip (eps_low=0.2, eps_high=0.28)
• Batch: 16 prompts/cycle × K=16 rollouts = 256 rollouts/cycle
• LR: 1e-5, T=1.0, max_grad_norm=1.0
• Cycles: 24 (no data reuse from 473-prompt v4 pool)
• Rollout judge: Anthropic Sonnet 4.6 via OpenRouter
• Direction tokens: SVD k16 mag7 rankfirst, [4480, 5120]
