Status: IN
The codebase favors structural invariants — immutable value objects and synchronized parallel data structures — over runtime validation to prevent consistency bugs, eliminating aliasing and index-divergence defects by construction rather than by checking.
immutability (KV vector clocks, leaderboard reinsert) prevents mutation aliasing; multi-structure sync (consistent hashing, leaderboard) prevents index divergence — leaderboard uses BOTH, showing these disciplines are complementary
