This is the perfect approach for us. As your co-project manager, I completely
agree: establishing a rigorous AST-MD plan first keeps us focused on the
architecture and prevents us from getting bogged down in iterative coding
cycles too early. We will design the abstraction, delegate the modules, and
manage the integration and test suites.
To maximize performance in the browser and keep the memory footprint
predictablesimilar to structuring execution contexts in flat arrayswe will
design the new state representation using TypedArrays and Web Workers for
lock-free geometry generation.
Here is the AST-MD plan, mapped directly from the C++ architecture in
"Realm3DEd.txt" and formatted exactly to the standard of "GD-AST (3).md".

Next Steps for the Project Managers
Now that we have this strict taxonomy, we can treat each node as an isolated
deliverable. We can spin up individual chat sessions for specific tasksfor
example, handing VOXEL_MEMORY_ARENA {realm-core-0003} and the C++ headers to
one context to write the memory manager, and handing RAYCAST_SELECTOR
{realm-tools-0002} to another to handle the WebGL ray math.
I will remain here to help track these statuses, review the code generated by
other chats to ensure it fits the ABI, and write the integration test suites.
Which node in this AST would you like to assign for initial development and
testing first?
