summary

Argues that connascence is a practical taxonomy that generalizes coupling and cohesion into three axes — degree, locality, strength — and shows concrete refactorings: replace positional parameters with typed objects to eliminate connascence of position, validate or encode time fields with enums to remove connascence of value, extract shared checksum/algorithm into one class to stop divergent change, enforce builder order with staged interfaces, and replace test sleeps with event hooks. Reports a surprising operational bug class — connascence of manual tasks — where build scripts and message types couple systems outside code.
