Why Replayable Output Matters for Debugging

If you miss output, you miss the truth. Replayable output lets you see what happened while you were away and removes the guesswork.

The short answer

Without replay, long-running jobs become unreliable because you cannot see the full timeline. With replay, reconnects become safe.

Why this matters

• debugging depends on complete context,
• reruns waste time and cost,
• confidence comes from continuity.
