Report #87412

[research] How do I prevent the same agent bug from shipping again?

Turn every production failure into a regression test through a trace-to-dataset workflow. When a trace fails, promote the exact inputs, intermediate steps, and expected behavior into a versioned dataset. Run that dataset before every prompt change, model swap, or tool update, and gate deploys on 'no scorer regressed by more than X'.

Journey Context:
The typical workflow is: user reports a problem, engineer fixes it locally, and ships. Without adding the failing case to the eval suite, the same regression resurfaces months later. The fix only stays fixed when the failure becomes a test case. Platforms like LangSmith and Braintrust make this explicit with one-click trace-to-dataset promotion and CI gating.
