The repo's quality profile (high algorithmic sophistication, low engineering discipline) is locked by two independent mechanisms operating at different structural levels: structural inseparability means the same mechanisms produce both algorithmic quality and engineering neglect (so changing one changes the other), while the self-reinforcing equilibrium means the submission-optimized feedback loop perpetuates both sides independently of structure — neither incremental improvement nor structural refactoring alone can alter the quality balance.
Structural inseparability and self-reinforcing equilibrium are independent locking mechanisms — the first prevents targeted fixes, the second prevents drift toward better engineering — their conjunction makes the quality profile doubly locked.
Depends on (SL): quality-inversion-structurally-inseparable, quality-equilibrium-self-reinforcing
