Changes

​
Bug Fixes

  • Prevent null dereference when finalizing streaming responses with no current attempt
    • packages/polyglot/src/Inference/Data/InferenceExecution.php
      • Null-safe access to currentAttempt in withFinalizedPartialResponse() and withFailedFinalizedResponse()
    • packages/polyglot/src/Inference/Data/InferenceAttempt.php
      • Null-safe withFinalizedPartialResponse() using empty PartialInferenceResponseList when needed
  • Console display stability in evals
    • packages/evals/src/Console/Display.php
      • Replaced invalid ImmutableDataMap::except() usage with safe filtering of toArray() output
      • Fixed constant name COLOR::BOLD → Color::BOLD

​
Behavior/Compatibility

  • Groq driver request body cleanup
    • packages/polyglot/src/Inference/Drivers/Groq/GroqBodyFormat.php
      • Removed redundant max_tokens → max_completion_tokens conversion (already handled by parent)

​
Immutability & Usage Accounting

  • Immutable accumulation for usage data to avoid inadvertent mutation/double-counting
    • packages/polyglot/src/Inference/InferenceResponseFactory.php
      • Use withAccumulated(...) when combining partial usage
    • packages/addons/src/StepByStep/State/Traits/HandlesUsage.php
      • Replace clone+mutate with withAccumulated(...)
    • packages/evals/src/Traits/Experiment/HandlesAccess.php
      • Compute experiment usage on demand by accumulating execution usages immutably
    • packages/evals/src/Experiment.php
      • Removed cached $usage and post-run accumulator; observations/summary rely on computed usage

​
Notes

  • This release focuses on correctness and immutability:
    • Eliminates potential fatals in streaming finalization and console display
    • Standardizes usage accumulation to immutable patterns across modules
