The four screening layers
Every clean checkpoint run depends on four layers: passenger scan, luggage check, document verification, and threat handoff. You can move quickly only when all four layers stay reliable. If one layer is weak, faster play usually creates more mistakes instead of more cash.
Passenger Screening
Scan-first route, recovery habits, and queue-pressure decisions.
Checkpoint Guide
Station order, solo and team roles, and reset decisions.
Scanner Tips
Read suspicious signals before rushing the next traveler.
Luggage Check
Bag ownership, prohibited-item review, and missed-item recovery.
Security Guard Role
Threat response that protects the line instead of abandoning it.

A step-by-step table for scan, luggage, documents, and threat response.
How to diagnose failures
If a run fails before threats appear, look at scan, luggage, and documents first. If a run fails after threats appear, ask whether the checkpoint was already stable. A boss attempt built on a messy line usually fails for two reasons at once, which makes it harder to learn from.
| Failure signal | Likely layer | Next action |
|---|---|---|
| The line feels too fast to read. | Passenger scan | Slow down and consider scanner-flow upgrades. |
| Wrong items slip through. | Luggage | Use the checklist and prioritize bag reliability. |
| You hesitate on paperwork. | Documents | Read details in the same order every passenger. |
| Everything is fine until danger appears. | Threat handoff | Read boss prep and shift cash toward defense. |
Practice route
Play one round where the only goal is clean order. Do not chase badges. Do not rush a final threat. After the round, write down the first broken layer and open the matching page. If you cannot identify the layer, use the full checklist for one more run.
How the new screening pages fit together
Use the detailed screening pages as a troubleshooting tree. Passenger screening explains the scan-first decision chain. Checkpoint explains how to keep stations readable. Scanner tips focuses on the first signal, while luggage check covers the hidden risk layer that players often rush. Security guard role connects screening to criminals, disasters, and boss pressure.
This structure mirrors the way a real run breaks. A failed passenger route is rarely just one mistake at the end. It usually starts with one unclear layer, then spreads into the line. Pick the first unclear layer and fix that page before reading the next one.
FAQ
Is screening more important than upgrades?
Early on, yes. Upgrades help most when you already know which screening layer is weak.
Why create a screening hub?
Because many failures look like general chaos until you separate scan, luggage, document, and threat layers.
What page should I use during play?
Use the full screening checklist. This hub is for choosing the right next guide.
