The codebase exhibits two complementary simplicity strategies — preferring simpler algorithms (loose but admissible heuristics, brute-force at pedagogical scale) and constraining existing structures for correctness (immutable values, synchronized collections) — that appear mutually compatible: simpler algorithms tend to have fewer edge cases that structural constraints must handle, and constraining existing structures is more tractable when the algorithms operating on them are straightforward.
Algorithmic simplicity reduces the surface area that structural discipline must protect, and vice versa
