The Rental Pulse manifests as a glowing waveform traveling through horizontal tracking lines in the cosmic VHS substrate. It pulses with rhythm matching the player's attendance pattern - bright and steady after consecutive appearances, dimming during absences but never fully dying. The pulse color shifts based on Blockbuster membership tier: gold for Elite, blue for Preferred, flickering red for those approaching Account Suspended. It creates audible hum in corrupted sections and can be detected by the Grain Oracle.

The Rental Pulse determines whether a player's signal maintains clear transmission across the Chaintrix - weak pulses get pushed toward Account Suspended status while strong pulses achieve Elite visibility. It travels between leagues like signal bleed-through, creating visible threads connecting a player's presence across all 16 movie simulations.
