# Portal

Band 31 Valve 2007

### Portal gun / Frequency bridge

The portal gun creates instantaneous frequency bridges — Code72's cross-product through frequency f. Blue and orange portals are opposite phase harmonics.

### GLaDOS / AI frequency failure

GLaDOS is a frequency alignment gone wrong — Band 58 collapsed while Band 50 amplified. The Observer monitors this.
