Storage Slot Collision Detector for Unstructured Storage and Diamond Proxies

[Fatimasanusi]

Upgradable contracts and EIP-2535 Diamond Proxies frequently suffer from storage layout collisions where new implementation variables overwrite critical authorization flags or token balance storage slots. We need an automated layout diff engine that detects overlapping storage slots across implementation versions.

Acceptance Criteria:

• Extract and parse contract storage layouts across implementation contract iterations.
• Identify conflicting storage slot offsets, specifically targeting diamond facets and unstructured proxy storage locations.
• Flag upgrade candidates that shift existing slot indexes without dedicated storage gap padding.
