ERC6900TypesLib

Title: ERC6900TypesLib

Authors: David Dada <daveproxy80@gmail.com> (https://github.com/dadadave80), Modified from ERC-6900 reference implementation (https://github.com/erc6900/reference-implementation)

Pure pack/unpack helpers for the ERC-6900 packed value types ModuleEntity / ValidationConfig /

IERC6900); these helpers are written fresh. Layout (big-endian / left-aligned within the type):

ModuleEntity (bytes24): address module [0..19] ‖ uint32 entityId [20..23]
ValidationConfig (bytes25): ModuleEntity [0..23] ‖ flags [24]
HookConfig (bytes25): ModuleEntity [0..23] ‖ flags [24]

ValidationConfig and HookConfig share byte 24 but interpret its bits differently — never decode a flag byte with the other type's masks (_VALIDATION_* vs _HOOK_*).
