# Temporal defects

Five deterministic temporal signals and the limited claim each can support.

## Transcript

- **00:00:00.000–00:00:06.000** Measure flicker as a luma pulse while content stays fixed.
- **00:00:06.000–00:00:12.000** Duplicate fingerprints expose stutter without inventing motion.
- **00:00:12.000–00:00:18.000** Mask hard cuts before measuring gradual color drift.
- **00:00:18.000–00:00:24.000** Laplacian variance can reveal a bounded sharpness collapse.
- **00:00:24.000–00:00:30.000** Neighbour disagreement is evidence of incoherent motion, not a semantic label.
