Additional Notes
Why does OrderOps care about invariants in __post_init__?
Track: Python
Topic: Domain Modeling
Focus: Invariants In __post_init__
Python: Invariants In __post_init__
Answer
Because the toolkit now carries orders, lines, customers, and inventory concepts that deserve clearer state and behavior than raw dictionaries provide, and this topic keeps that workflow explainable and reliable.
The curriculum uses one continuous project so each Python concept lands in a real engineering context.
