This is a speculative theory note written by a student in India with no institutional affiliation. It proposes a physical mechanism "dissipation event clustering", that may explain why directed percolation statistics emerge from the fluid dynamics of pipe flow turbulence transition. No experiments were performed and nothing here is proven. It is posted solely to put the idea on record and invite scrutiny from researchers with the resources to test or disprove it.
