Start with the linked GitHub Actions run for the Bun Unit Tests job and inspect the failing `error: expect(received).toBe(expected)` assertion. Reproduce the failure and trace it to the relevant test or setup; done means the test passes reliably in repeated Bun CI runs without masking the assertion.
