Unixification

What happens when you scale complexity before you standardize interfaces?

Principle

Unixification is the operating discipline of designing small, testable units with stable contracts.

Rule	Engineering Meaning
One job	Each unit has one clear responsibility
Small surface	Inputs and outputs are explicit and minimal
Stable contract	Interfaces change slowly and deliberately
Composable parts	Units can be assembled into larger systems
Test in isolation	Failures are attributable and diagnosable

Apply this sequence when variance and coupling increase:

Define Unit -> Freeze Contract -> Test Isolated -> Compose Incrementally -> Measure Variance

Condition	Action
High coupling	Break system into explicit units before integration
High failure ambiguity	Add contract tests and trace logging
Repeated integration rework	Stabilize interfaces before adding features

If these do not improve, unixification is being claimed but not practiced.

What is the smallest unit in your domain that could have a stable contract — and what would that unlock?

Where does failure ambiguity slow you down most, and which interface is the source?
What would you need to freeze now so innovation could move one layer up?
If your system cannot describe its capabilities, who bears the cost of that ambiguity?
