feat: integrate continuous building via Project Genie simulation

[Igor Holt (igor-holt)]

This PR integrates features inspired by Project Genie to enable live, continuous building of the Yennefer Observatory environment.

Changes included:

1. Updated scripts/genesis.cjs to output generated evolution components to yennefer-observatory/src/components/mutations so they can be imported dynamically by Observatory.jsx.
2. Expanded the Visionary's mutations list to include directives for "continuous dynamic landscapes" and "macro-scale makerspace workbenches."
3. Adjusted the generateEvolutionComponent logic to generate these new environments dynamically with procedural React Three Fiber logic based on the text prompt directives.
4. Added fallback logic for journal creation to ensure smooth continuous execution when running without explicit permissions in /home/yenn/.

Code Review

This pull request introduces 'GenieWorld' environment mutations, such as dynamic landscapes and makerspace simulations, and refactors the component generation logic to support custom Three.js animations and additional meshes. Feedback was provided to improve the robustness of directory creation and mutation selection logic. Additionally, there are suggestions to optimize the performance of procedural landscape animations by avoiding frequent CPU-to-GPU buffer uploads and to simplify the string construction for library imports.

The directory creation logic is redundant and lacks robustness. fs.mkdirSync with { recursive: true } handles existing directories automatically, making the fs.existsSync check unnecessary. Additionally, the fallback path creation in the catch block is not protected by its own error handling, which could lead to an unhandled exception if the fallback location is also unwritable. It is also recommended to ensure the PATHS.body directory exists, as it has been moved to a new location.

try {
  fs.mkdirSync(path.dirname(PATHS.journal), { recursive: true });
} catch (err) {
  PATHS.journal = path.join(__dirname, '../logs/genesis_journal.jsonl');
  try {
    fs.mkdirSync(path.dirname(PATHS.journal), { recursive: true });
  } catch (e) {
    // Fallback failed, script will likely fail on write
  }
}
try {
  fs.mkdirSync(PATHS.body, { recursive: true });
} catch (e) {}

The selection logic for Genie simulations is fragile as it assumes the target mutations are always the last two elements of the array. This will break if the array order changes or if new mutations are added. A more resilient approach would be to filter the mutations based on their content.

    const genieIndices = mutations.map((m, i) => (m.content.includes("landscape") || m.content.includes("makerspace") ? i : -1)).filter(i => i !== -1);
    const idx = isGenieSim && genieIndices.length > 0
        ? genieIndices[Math.floor(Math.random() * genieIndices.length)]
        : Math.floor(Date.now() / 1000) % mutations.length;

This animation logic has performance and efficiency issues. Updating geometry attributes (positions.setZ) and setting needsUpdate = true inside useFrame forces a CPU-to-GPU buffer upload every frame, which is expensive. For procedural landscapes, a vertex shader is preferred. Additionally, setting rotation.x to a constant value every frame is redundant; this should be set once on the mesh component's initial props.

The logic for constructing the importedDrei string is difficult to read and maintain. Using an array to collect imports and joining them with a comma is a cleaner and more robust approach.

    const imports = [];
    if (material.includes('MeshDistortMaterial')) imports.push('MeshDistortMaterial');
    if (material.includes('MeshWobbleMaterial')) imports.push('MeshWobbleMaterial');
    importedDrei = imports.length > 0 ? `import { ${imports.join(', ')} } from '@react-three/drei'` : '';

Code Review

This pull request updates the genesis.cjs script to support 'GenieWorld' simulations by adding new mutation types for landscapes and makerspaces. It also introduces environment-specific path handling for journal logs and refactors the React Three Fiber component generation to support custom logic and additional meshes. Feedback was provided to improve the robustness of the directory creation logic, make the mutation selection more dynamic to avoid fragile indexing, and simplify the string construction for library imports.

The directory creation logic is redundant and slightly fragile. fs.mkdirSync with the { recursive: true } option already handles existing directories gracefully, making the fs.existsSync check unnecessary. Additionally, the fallback logic can be streamlined to avoid nested checks and redundant calls.

try {
  fs.mkdirSync(path.dirname(PATHS.journal), { recursive: true });
} catch (err) {
  PATHS.journal = path.join(__dirname, '../logs/genesis_journal.jsonl');
  fs.mkdirSync(path.dirname(PATHS.journal), { recursive: true });
}

The logic for selecting Genie-specific mutations is fragile as it relies on them being the last two elements in the mutations array. If the array is expanded or reordered in the future, this logic will likely pick incorrect mutations for the simulation. It is better to dynamically identify the relevant indices.

    const genieIndices = mutations.map((m, i) => (m.content.includes("landscape") || m.content.includes("makerspace")) ? i : -1).filter(i => i !== -1);
    const idx = isGenieSim && genieIndices.length > 0
        ? genieIndices[Math.floor(Math.random() * genieIndices.length)]
        : Math.floor(Date.now() / 1000) % mutations.length;

[genesis-code-assist]

The string construction for importedDrei is brittle and difficult to maintain due to the nested ternary operators and manual comma handling. Using an array to collect required imports and joining them is a much cleaner and more robust approach.

    const imports = [
      material.includes('MeshDistortMaterial') && 'MeshDistortMaterial',
      material.includes('MeshWobbleMaterial') && 'MeshWobbleMaterial'
    ].filter(Boolean);
    importedDrei = imports.length > 0 ? `import { ${imports.join(', ')} } from '@react-three/drei'` : '';
