# Waiting-Hall Bridge Prefix Alignment

This is a reuse-only check using the bridge key `sample_id + trajectory_id + event_index`.

- Bridge file: `C:\Users\yauki\Documents\design\Collatz\paradoxical-sequence\results\2026-06-29_paradoxical-sequence\csv\exit_neighborhood_per_trajectory.csv`
- Waiting-hall label file: `C:\Users\yauki\Documents\design\Collatz\waiting-hall\reports\collatz-waiting-hall_csv_2026-06-30\waiting_hall_interior_detail.csv`
- Bridge-to-waiting matched event keys: 74116
- Bridge-validated event keys overlapping existing light audit seed/split sample: 532
- H-expanded joined rows: 3382
- Verdict: `partial_prefix_shadow`
- Same-direction targets: future_net_log_change
- Different or unresolved targets: future_max_log_drawdown

This does not start a standard/full audit, add targets, thicken bootstrap, or change the waiting-hall labels.
