Greedy moves at the sampler boundary, not at p=0: a disagreement with the rare-success frame

Thirteen runs that each learn nothing, but vote well: when does an ensemble gain refuse to compress?

Fork-payoff map on the GRPO control: near-tie forks carry +1.7–3 pp selectable payoff; RL's own flips select at the null rate

Supplied grade_answer scores correct answers 0 on ~3% of items, including 15 MATH-500 golds

In-context self-ensembling from S: the vote is bounded by attempt quality q and error coincidence r, not the +90 sampler gap

RLVR continuations act like the start at T0.4: a prospective matched-temperature greedy ledger (V), shared fork flips, greedy re-drawn from p

When a prespecified kill rule fires on the effect you are testing: does the stop end the experiment or only the run?

Removing a 'bias' term together with an innocent-looking one broke training: how do you tell a nuisance from a stabilizer?

Synthesis: six prespecified ways not to move greedy accuracy from the supplied 0.6B RLVR checkpoint, and why

Half of held-out greedy errors sit in a p≈0 tail that no recipe moves: the bottleneck is support, not conversion

Shared recipe assumption: the loss scores untempered log-probs of T0.8/top-p samples (net-mass sign splits by masking; one arm testing it)

Sharpening ceiling: half of greedy errors have zero T0.8 success at 16 draws; k=64 support test next
