      "outcome": "The core implementation is correct: the catch block properly detects transient errors, moves tasks to \"todo\" for retry, logs appropriately, and avoids calling `onError`. Tests cover both the detector module and executor integration. However, the `index.ts` exports are missing as required by Step 4, which blocks external consumers from accessing the new classification functions."

The code follows the existing patterns in the codebase, properly imports the new `isTransientError` function, and implements all requirements from the step specification."
