## Background when a user uses `experimental_transform`, the doStream telemetry span `ai.streamText.doStream` was recording untransformed values for `ai.response.text` and `ai.response.providerMetadata` this is also so that with the new telemetry approach, we have feature parity with how the new flow works when setting the spans. see [comment](https://github.com/vercel/ai/pull/13051/changes/#r2885652481) ## Summary essentially split the doStreamSpan so that we set ai.response.text, reasoning and providerMetadata by reading from the fully-processed recordedSteps ## Manual Verification na ## Checklist - [x] Tests have been added / updated (for bug fixes / features) - [ ] Documentation has been added / updated (for bug fixes / features) - [x] A _patch_ changeset for relevant packages has been added (for bug fixes / features - run `pnpm changeset` in the project root) - [x] I have reviewed this pull request (self-review)
