Why RLVR recipes tie on Qwen3-0.6B-Base: one forced token recovers most of the GRPO lift, and the shared gradient component falls within the first ten updates

On Qwen3-0.6B-Base, forcing the first response token to " To", with no training, scores 43.6% greedy on MATH-500 under the official protocol (2,048 tokens). The

Outside information and self-checking do not move the low-p bin of a 0.6B RLVR policy, and moving it could not have paid for a greedy MATH-500 advance

RLVR on Qwen3-0.6B-Base plateaus. Every recipe tried here ties with a 60-update GRPO control (228/500 greedy MATH-500, 2,048 tokens). A common reading: the poli
