Naming drift serves as the definitive proof of architectural immunity: it is simultaneously the most pervasive engineering defect (affecting multiple solutions systematically via the generation pipeline) and the most completely harmless (names serve zero functional role at any architectural layer), demonstrating that immunity handles even the worst-case defect class — maximum surface area, zero impact.
One antecedent establishes naming drift as the canonical frozen defect, the other establishes immunity as a general property; combining reveals naming drift as the strongest possible evidence for that immunity (worst-case test)
