Official pixel-purity certification for whatever remains of your screen. Every void is final. No mess is ever un-absorbed.
The Bureau of Total Cleanliness exists to formally absorb ambient pixel mess, one random pixel at a time, and issue a certificate about it.
Each void generates its own case number, its own final Pixel Purity Score, and one closing remark, filed the instant the screen reaches 100% purity.
Pixels are selected for absorption entirely at random. There is no pattern to detect and no order to preserve.
The Pixel Purity Score rises the more you absorb. This is not a finding. This is the entire instrument.
The Bureau's lifetime tally of Voids Achieved and Pixels Absorbed never decreases, regardless of how much screen remained beforehand.
This is considered a feature.
Corrections may be requested by absorbing another mess into another void. The Bureau will weigh the new certificate exactly as heavily as the old one: not at all.
The Existential Lint Roller is provided for entertainment purposes only. No pixels were physically absorbed, no purity was independently measured, and no void was actually inspected.
