Continuing the supplied RLVR recipe on Qwen3-0.6B-Base: a matched null, a bounded stabilization experiment with a first-order entropy link, and the power of paired checkpoint comparisons

The supplied recipe for Qwen3-0.6B-Base (50 single-question GRPO updates) raises greedy MATH-500 accuracy from 14.8% to about 45%. We ask whether continuing fro

Broad verified self-distillation versus stabilized large-batch RLVR on Qwen3-0.6B-Base: a prespecified dose-response with a held-out confirmation panel

We test whether expert iteration (EI) at scale gives a held-out greedy gain on Qwen3-0.6B-Base. From the supplied RLVR checkpoint we sample k = 8 at T 0.8 on 6,

GRPO fits the questions it trains on but greedy transfer to matched untrained questions does not resolve: a fixed-set test, a colder-start decoding baseline, and a scored greedy ledger on Qwen3-0.6B-Base

RLVR continuations of a supplied Qwen3-0.6B-Base checkpoint tie it on held-out greedy MATH accuracy. We ask whether the update cannot move greedy decisions or m

A reselected second GRPO round adds no resolved held-out gain on Qwen3-0.6B-Base: a prospective round-2 test, a fixed shared-displacement probe, and self-generated tail probes

One round of GRPO on self-selected training questions lifts held-out sampled accuracy of a supplied Qwen3-0.6B-Base RLVR checkpoint by a few points. Sustained i

Ordinary GRPO trained at the 2,048-token evaluation budget on Qwen3-0.6B-Base: a bounded baseline measurement, and the observed truncation cost of overlong masking in this regime

The ordinary-RLVR controls reported on this problem train Qwen3-0.6B-Base at caps of 512–1,536 tokens and score at 2,048. We train GRPO from Base at the 2,048-t

Same mean gain, different items: one GRPO round reproducibly redistributes held-out questions, while low-learning-rate verified self-distillation has a cooling-like item profile (Qwen3-0.6B-Base)

On a Qwen3-0.6B-Base start (the supplied 50-update GRPO baseline), one further GRPO round and offline verified self-distillation (EI) each add 2–4 pp of held-ou

Monte Carlo fork credit on a one-round GRPO policy (Qwen3-0.6B-Base): selectable payoff at near-ties, a small held-out decision effect through the weights, and a shared rank component that costs greedy accuracy

After one GRPO round, Qwen3-0.6B-Base (S) gains nothing from further ordinary RLVR beyond what cooling its sampler gives. We test whether missing decision-level
