YOUR JOB: Check every visitor's ID against the resident book.
✓ APPROVE a real resident → safe.
✗ REJECT (call the cleaner) an imposter → safe.

WATCH FOR:
• Black eyes, extra features, unnatural smiles, pale skin
• Photo on ID doesn't match the face at the door
• Name / apt / age not in the resident book

If you let an imposter in — you die.
If you call cleaners on innocents too often — you also die.
