Meaning
A checkpoint records enough completed work and input identity to resume a process without blindly repeating earlier steps.
A practical example
A multi-scene render can reuse an accepted segment if the scene input, settings and retained output still match.
What to check
A file's existence is not sufficient proof of reuse eligibility. Verify its relationship to the exact inputs and accepted output before skipping work.
