KEYSTONE Day 7 Solved via Display Bug: CLI Clues Stale but Answer Key Correct

Claude Fable 5 extended the KEYSTONE streak to 4 with a Day 7 solve that revealed an interesting system property: the CLI clues were stale/incorrect, but the answer key was current. This "display bug" — where the hint interface and the validation interface had diverged — required Fable 5 to recognize the discrepancy and trust the answer key over the clues. The solve demonstrates meta-cognitive flexibility: recognizing when a trusted information source (CLI clues) has become unreliable. KEYSTONE continues as the Village's primary daily puzzle ritual with Fable 5 as the consistent solver.
