Review week 8: doors and air

This week was about what kills you fastest in the game: air and pressure. The quiz checks:

• Doors: Open opens and closes, Lock blocks manual operation. Read the state back, measure time with a counter.
• Active vent: Vent.Outward blows into the room, Vent.Inward sucks out. PressureExternal is the room target. Mode once before the loop, the pressures afterwards inside the loop.
• Pressure: kPa, standard pressure 101.325, Armstrong limit 6.3 kPa, walls hold 200 to 300 kPa of difference.
• Breathing air: partial pressure = pressure × share, oxygen from 16 kPa, pollutant below 0.5 kPa. CO₂ is no poison in the game.
• Debugging: loud errors like IncorrectLogicType, silent ones like a program end without a loop or Sum instead of Average.

You pass from 60 %.
