# Source Blockers

- `visible_land_count`: Static source prefab has 36 visual grid cells. The first-milestone spec requires 24 visible land plots, but the runtime rule selecting those 24 is not yet decoded.
- `background_texture_binding`: Background ImageAsset entries are located, but final texture/SpriteFrame binding for Cocos 4 import is not yet resolved from metadata.
- `cocos4_cli_build`: Cocos 4 alpha CLI reaches engine init, then fails because node_modules/gl/build/Release/webgl.node requires NODE_MODULE_VERSION 140 while local Node 24 provides 137.
