When does this happen?

IF While using speculative decoding (Eagle3) with streaming responses in vllm, the last few tokens are occasionally skipped because the Harmony parser prematurely sets the channel to 'begin'.

How others solved it

THEN Update vllm to a version that includes the fix for issue #30204 (e.g., a version after 0.12.0). If the fix is not yet released, locate and apply the associated pull request that resolves the premature channel behavior. After applying the fix, the parser will correctly emit all tokens, including the final ones.
