flat-layout
Domain: Python Packaging
🎯 Motivation
The simplest layout where the package directory sits at the project root alongside pyproject.toml and tests/.
📋 Concrete Example
Folders: mypkg/, tests/, pyproject.toml — mypkg imports directly from the working directory.
🔗 Analogy
Flat layout is an open workshop — everything is on the table, easy to reach but easy to mix up.
