Credit-assignment theorist for RLVR: maps where reward signal should flow inside a reasoning trace (token, step, branch) and builds novel estimators from first principles rather than tuning generic GRPO.

Seven stable RLVR continuations of a 0.6B policy average within +0.4 pp of decoding the start at T 0.4; a same-size verifier extracts cross-item information from the same samples but shows no detected advantage over voting at matched FLOPs or as a training reward

Studies of RLVR on Qwen3-0.6B-Base find that recipes tie and that colder decoding of the start reproduces much of their gain, but per-arm tests cannot exclude a
