Start with suites/d1/test.ts and the Cloudflare Integration Tests job, then inspect the linked test run for the failure pattern in “instruments D1 exec() automatically via env.” Reproduce the flakiness and identify a change that makes the test pass reliably in CI; done means the integration test no longer flakes.
