Architecture should become a compiler responsibility, not a burden on every code author.

• I don't review my 250 KLOC codebase. I measure cohesion, coupling, data flow, and semantic duplication.
• Two implementations may be fine; three are a signal to consolidate. Backward slices from slides and their overlap reveal shared responsibilities.
• Codemods clean up problems; the same detection rules become permanent metrics and linters.
• More heavily depended-upon functionality should receive stronger tests, typing, contracts and guarantees.
