## Storage Layout Invariance

Storage layout invariance is the requirement that the order and type of variables in a smart contract remain consistent across different versions of the contract to prevent data corruption. When a contract is upgraded, new versions must append new variables to the end of the existing storage layout rather than reordering or inserting them in the middle.

If this principle is violated, the contract will read the wrong memory slots, resulting in incorrect balance calculations or failed state transitions. In financial protocols, this is a critical safety rule that ensures continuity of user positions and collateral during upgrades.

Maintaining this invariance is essential for the reliability of long-lived decentralized financial systems.
