Voice AI QA observability

QA observability makes it possible to review what was tested, what happened, and which decision followed. Keep the test case, input conditions, output, reviewer decision and retention rule together.

Separate full results from cohort results and record uncertain cases for human adjudication. Keep the review method fixed when comparing changes.

Use the evidence trail to connect an error type with a proposed change, then rerun the fixed holdout set and record the outcome.
