M14 Mental Model

This is your go-to reference when Rust's ownership system feels like it's fighting you. It breaks down the core mental models you need, like treating ownership as a unique key handover and understanding why multiple readers or one writer is the rule. The visualization tables showing stack and heap relationships are genuinely helpful, and the "coming from other languages" section cuts through common misconceptions fast. Best used when you're staring at borrow checker errors and need to step back from the syntax to understand what safety guarantee you're violating. The trace up and trace down sections connect it to other m-series skills nicely, making it a hub for learning rather than just a reference card.
