Ue5 Architecture

Quick Start

• Collect current module list, *.Build.cs, and major gameplay/UI systems.
• Propose one target module graph before writing code.
• Output module responsibilities and ownership in a table.

Workflow

• Identify runtime, editor, UI, networking, and data modules from current codebase.
• Define Public API for each module as minimal headers and Blueprint surface.
• Define Private implementation boundaries and include rules.
• Define PublicDependencyModuleNames and PrivateDependencyModuleNames per module.
• Report risks: circular includes, over-exposed reflection types, and cross-layer references.

Constraints

• Keep UCLASS/USTRUCT/UENUM only where reflection is required.
• Prefer forward declarations in headers; include concrete headers in .cpp.
• Do not move types across modules without listing migration impact.
• Keep naming aligned with Unreal conventions (U, A, F, E prefixes).

Failure Handling

• If ownership of a class is ambiguous, place it in runtime module first and log a TODO to split after usage mapping.
• If dependency graph becomes cyclic, extract shared contracts into a thin common module.
• If Build.cs dependencies are uncertain, choose minimal set and verify compile paths immediately.

Escalation

• Escalate when a refactor requires asset redirectors, class renames, or package path migration.
• Escalate when module split changes public Blueprint class paths used by existing content.
