EXPERIMENT 13 VERIFICATION
==========================

Verified source markers:
- RESEARCH EXPERIMENT 13
- EMPIRICAL NATURAL-DEPENDENCY MOTIF MIRRORING
- BUILD TAG: STRESS-EXP13-EMPIRICAL-NATURAL-MOTIF-MIRRORING-001
- EXPERIMENT_NUMBER = 13
- Dataset mode: EMPIRICAL_NATURAL_DEPENDENCY_MOTIF_MIRRORING_DATASET

Implementation boundary:
- Frozen Experiment 23 architecture retained.
- Standard seeded queues remain the foundation.
- One natural three- or four-passenger motif may be mirrored per aisle.
- All non-motif passengers retain their seeded relative order.
- No seat, row or serving-aisle assignment changes.
- No runtime holding, inserted region, artificial confirmation,
  asynchronous execution, behavioural modelling, backward movement,
  overtaking or aisle switching.

Validation:
- Java source compiled successfully.
- Full 30-pair / 60-execution verification run completed successfully.
- Runtime output confirmed Experiment 13 startup and completion banners.
- Verification results are not included as official Experiment 13 findings.
