handler-drift
A mock handler that cannot match the URLs your code calls.
No decided findings.
Shown with --all. Never gates, even with an override.
Hidden by default
Its review dropped it: open-source suites gave it almost no handlers it could decide without configuration.
It still runs: spirolo check --all shows its findings, labelled, and it never fails the build, even with an override.
What it reports
An MSW or nock handler's URL pattern cannot match any URL under the production base URLs you declared, so it never intercepts a request. The tests that rely on it run against an unmocked or fallback response.
What to do
Change the pattern to the base the code really calls, or delete the handler.
What it reads
The rule needs urlSources (and env for URLs built from environment variables) in the config.
spirolo explain handler-drift prints the same claim and status from your installed binary.
