Under the hood
Feature-bad/feature-sad telemetry now sanitizes the error_code field before sending it
What
The internal telemetry events tengu_feature_bad and tengu_feature_sad now validate the error_code value they record. If the value doesn't match an expected pattern, it gets replaced with a placeholder value of nonconforming before being sent.
Why
This keeps malformed or unexpected error codes from being recorded verbatim in telemetry, making the data more consistent and predictable to analyze.
