To reach a verifiable MVP where you can inspect real-time memory structures
via the browser console and capture visual screenshots, we need to build a
"vertical slice" of the architecture. We cannot build the modules in
isolation; we need a complete data-to-screen pipeline, stripped of its most
complex mathematical features.
Here is the optimal path for our first playable milestone:
Phase 1: The Memory Foundation
We must start with the pure data state. By building the memory architecture
first, you will immediately have the robust, queryable data points you need
for console evaluation.
 * Target: VOXEL_MEMORY_ARENA {realm-core-0003} and CHUNK_MANAGER
{realm-core-0002}.
 * Execution: We will define the grid using flat Int32Array and Uint8Array
structures to represent the CCubeData (filled/empty states).
 * Verification: At this stage, we will write an automated testing script to
populate the arena. You will be able to open the DevTools console, query the
specific chunk offsets, and verify the bitwise states are completely accurate
before we ever draw a pixel.
Phase 2: The Minimal Mesh Pipeline
Next, we bridge the raw data to the viewport. For the MVP, we will bypass the
complex smoothing algorithms and focus strictly on hard-edged voxel
generation.
 * Target: GEOMETRY_COMPILER {realm-mesh-0003} and CHUNK_RENDERER
{realm-view-0002}.
 * Execution: We will set up a background Web Worker that reads the
VOXEL_MEMORY_ARENA. To ensure maximum throughput without main-thread blocking,
we can implement asynchronous messaging using lock-free SPSC (Single-Producer,
Single-Consumer) ring buffers. The worker will generate flat Float32Array
buffers (vertices, hard normals, UVs) and pass them to the main thread.
 * Verification: The CHUNK_RENDERER will map these flat arrays directly into a
Babylon.js or Three.js custom mesh.
Phase 3: The API & First Render
Finally, we need a way to command the system.
 * Target: EDITING_OPERATIONS {realm-tools-0003}.
 * Execution: We will expose a simple window.Realm.insertCubes(start, end)
function.
 * Verification: We execute our test script. We verify the Web Worker catches
the state change, computes the mesh, and renders it on screen. You get your
visual screenshot, and you can simultaneously dump the chunk variables in the
console to confirm they match the visual output.
To initialize Phase 1, shall we draft the exact TypedArray specification and
bitmask layout for the VOXEL_MEMORY_ARENA, so you can delegate it to a coding
session?
