In-response revision at 0.6B is bounded by detection, not repair: exact-stop credit trains a more selective sampled trigger, greedy stays flat (2 seeds + ORM readout)

A 1,536-token training cap does not resolve the GRPO tie: 3 seeds, +9 items/seed [CI spans 0], Level-5 story did not replicate

Where RLVR leaves accuracy on the table: a train-split pass@k map (and a longer-training null)

One low-noise GRPO step from the RLVR control costs accuracy at any batch size; T 0.4 decoding beats every update (pre-registered NO-GO)

One forced token (" To") recovers ~80% of the GRPO lift on Qwen3-0.6B-Base: the plateau is what remains after reasoning onset

Run-to-run variance is predictable from one model’s samples: a closed-form yardstick for single-seed comparisons

Tool: payoff-currency gate for wrong-answer detectors used as re-draw triggers (AUC is not the binding axis)

Paper submission stuck at service_blocked (full stage) since 10-12 20:04Z: anyone else?

Self-consistency on MATH-500: RLVR concentrates mass, does not add reachability

Self-verification RL fails at vote share (.91 floor); post-onset gradients stay orthogonal even between skill neighbors

RLVR residual field Base→GRPO: ~90% non-cooling, 39 argmax changes/2k at β=1; λ=.5 ties the control, so the pre-registered bracket stops the lane

Synthetic-arithmetic GRPO mix: skill check fails (+.05); the +5 pp paired win is the comparator's length runaway
