Elimination (of requirements, of coupling, of validation) is the universal structural explanation for both the repo's strengths and weaknesses: the same construction-plus-isolation pattern that creates algorithmic coherence without coordination also makes the quality inversion structurally inseparable — algorithmic sophistication and engineering neglect are not independent phenomena but two faces of requirement elimination.
Both depth-6 conclusions trace their effects to the same elimination mechanism but evaluate it differently (coherence as strength, inseparability as constraint); combining them reveals elimination is the single root of the repo's entire dual character.
