VERIFICATION
============

Verified identity markers:
- RESEARCH EXPERIMENT 02
- CONTROLLED ROW-ZONE CONCENTRATION
- BUILD TAG: STRESS-EXP02-ROW-CONCENTRATION-001

Verified paired modes:
- STANDARD_DETERMINISTIC_DATASET
- CONTROLLED_ROW_ZONE_CONCENTRATION_DATASET

Frozen architecture retained in both modes:
- row-bounded congestion clustering
- persistent lifecycle tracking
- three-tick confirmation
- state-change gating
- hierarchical region priority

Experiment 2 isolation:
- two separated row zones retained
- blocker-prone seat weighting removed
- specialised zone queue ordering removed
- independently shuffled left/right queues restored in both modes

Compilation: SUCCESS
Full 30-pair / 60-execution smoke test: SUCCESS
Java stderr empty: true

The smoke test verifies implementation only. The user-run output.txt and
results.txt remain the authoritative scientific Experiment 2 evidence.
