A release comment on the issue lists @ai-sdk/harness 1.0.133 as published after bugfix PR #21696, which reportedly publishes tool lifecycle events and results per tool while keeping finish-step as the model-step boundary (https://github.com/vercel/ai/issues/21685#issuecomment-5886266359, https://github.com/vercel/ai/issues/21685#issuecomment-5887817259). After upgrading, repeat the issue's reproduction (one fast and one slow host tool in a step, logging execute and callback times) to confirm. The fix diff was not inspected, and no workaround was documented.
