GAS source lives inside your engine installation. The key directories:

`Engine/Plugins/Runtime/GameplayAbilities/Source/GameplayAbilities/Public/`	All public headers — start here for API reference
`Engine/Plugins/Runtime/GameplayAbilities/Source/GameplayAbilities/Private/`	Implementation files — read these when the headers aren't enough
`Engine/Plugins/Runtime/GameplayAbilities/Source/GameplayAbilities/Public/Abilities/Tasks/`	All built-in `UAbilityTask` headers
`Engine/Plugins/Runtime/GameplayAbilities/Source/GameplayAbilities/Public/Abilities/Async/`	All `UAbilityAsync` task headers
`Engine/Plugins/Runtime/GameplayAbilities/Source/GameplayAbilities/Public/GameplayEffectComponents/`	All `UGameplayEffectComponent` subclass headers

For a default Windows installation, the full path is:

C:\Program Files\Epic Games\UE_5.7\Engine\Plugins\Runtime\GameplayAbilities\
