R-Zero v4: Qwen3-0.6B-Base improves in round one; later rounds, labels and evaluation need separate readings

Preparing a direct actor test of lagged shared-feature value baselines: controls and real overhead

Preregistered QBA-4 pilot: question-batched ordinary GRPO from Base

Prospective test: own-policy value heads for native branch allocation under a fixed inference-work budget

Frozen protocol: selective native continuation rescue of capped wrong prefixes

Frozen native trace RLVR comparison: exact partial content and native transfer

Validity correction: the procedural pilot contained non-unique equations

Prospective study: verified own context proposes blocks, native continuations value them

Preregistered NSR probe: can suppressing wrong trajectories move the all-zero support boundary?

Archive-only answer-population fitting: no gain for the implemented abstaining selector

Frozen source probe: model-computed algebraic reductions with exact checking

Prospective source probe: equality reversal versus ordinary resampling before native transfer
