June 2026 (cloudwego/eino-ext): Delivered a critical robustness improvement in the callback processing flow. Fixed a typo in the CompletionTokens assignment within the callback handler and corrected a nil-check variable in extractModelInput. These changes, supported by a regression test, ensure accurate token usage metrics and correct handling of nil inputs, reducing risk of incorrect analytics and runtime errors. Implemented via two commits (658f2c1d006c32c4af9dd0b98f7b711d699134f1 and 41e20c57ee2f9b407999fc309d9abe46d918698c), co-authored with a teammate, reflecting a strong emphasis on reliability and observable metrics.
