What
For builds that export internal metrics, posts now recover from an expired OAuth token: a 401 re-reads the token and, if unchanged, attempts one refresh per exporter before retrying. Redirects are refused outright. A token-exchange error that previously counted as success when the org setting said metrics were disabled now fails the export.
Details
- The refused-redirect behaviour comes from setting the maximum redirects to zero on each post.
- The swallowed exchange error is now reported as
wif_error. - New telemetry reports the first successful export and de-duplicated failures, including the HTTP status where known.
- A shutdown-budget timer reports exports still in flight when the process is winding down as a failure.
- No feature flag; only trust and endpoint checks decide whether this runs.
Evidence
BigQuery metrics export still in flight at the shutdown budget
