The repo's quality profile (high algorithmic sophistication, low engineering discipline) is a stable attractor selected by the domain itself: LeetCode's problem structure produces a closed strategy taxonomy that converges without coordination, and only algorithmic quality is rewarded by the judge — making any perturbation toward engineering investment self-correcting back to the current equilibrium.
Both depth-6 conclusions describe the same equilibrium from complementary angles (internal self-reinforcement vs external domain selection); combining reveals a dynamical stable attractor, not merely a persistent state
