Interview Prompt
A 14-day-old consumer-logic bug in the Flink job was just discovered. Plan the replay. Walk the section's three-leg checklist on this canvas: a retention window long enough to cover the cycle, an addressable-position mechanism, and an idempotent destination that absorbs replay. Make the structural change for any leg the canvas does not already satisfy.
