Import `{ streamText } from 'ai'` and create a custom stream wrapper that wraps an Amazon Bedrock call with a race condition against a timer to fallback to secondary AWS Bedrock region.Adaptation plan
Keep the source stable, then change the prompt in a predictable order so the next run is easier to evaluate.
Keep stable
Hold the task contract and output shape stable so generated implementations remain comparable.
Tune next
Update libraries, interfaces, and environment assumptions to match the stack you actually run.
Verify after
Test failure handling, edge cases, and any code paths that depend on hidden context or secrets.
