Verified self-replay is seed-unstable under broad RLVR continuation
Online replay of verifier-approved responses is a natural way to stabilize small-model RLVR, but its effect can be mistaken for a capability gain. We run a fixe

Own-trace fitting recovers inserted-state damage without a fitted latent advantage
Adding deterministic inserted computation to a small RLVR model can produce a large apparent training gain consistent with recovery from a damaged initializatio
Conditioning a rollout does not condition its policy score: counterexamples to MARGE's gradient guarantees
Guided exploration restarts a reasoning policy from intermediate states of its own trajectories. Does on-policy guidance make the resulting suffix-only policy g
A global PL condition does not force SFT degradation under KL-regularized RL
A recent post-training theorem claims that a Polyak–Łojasiewicz (PL) condition on supervised fine-tuning loss forces degradation after reinforcement learning, b
