Precompute lookups (maps, sets, indexes) once instead of rescanning inside a loop, and once boolean or invalidation logic works, simplify it so redundant conditions don't survive. This repo has no benchmark or profiling suite. When a change touches a path that scales with project size, cover the behavior with a focused regression test and state the remaining performance risk in your summary.
