There comes a point in every engineering organization where the repository stops feeling like a tool and starts feeling like regional infrastructure.
Folders become provinces. Build graphs become geopolitics. Somebody says “boundary” with the tone of a treaty negotiator and everyone else nods as if this is normal.
And still I defend the monorepo, because at least when everything breaks, it breaks in one place with a single ceremonial lockfile.
That is not convenience. That is culture.
