The Ghost Mismatch

**Scenario.** Your stress harness found one mismatch, but the input was regenerated with a new random seed and now nothing fails. First move? **Which approach is the best fit? The program only needs to print the letter.** **A)** Move on — it was a fluke **B)** Fix the seed: reproduce first, shrink second. An unreproducible failure is unfixable; re-seed with a fixed value and re-run the exact sequence **C)** Increase the input size in the generator **D)** Delete the brute force to speed up the loop
