Acid-Driven Proteolysis and Gluten Weakening

Falling pH activates flour's endogenous aspartic proteinases and increases gluten solubility, so an over-ripe or over-acidified starter degrades the protein network it is meant to inflate. Mild acidification tightens gluten and improves gas retention; prolonged acidification collapses it into a sticky, tearing dough.
