Grand Workshop: Passageways

Initial development alpha for Minecraft 26.3. Adds 32 pieces in honey oak, walnut, iron and brass: 16 functional courtyard gates plus entrance posts, finials, lintels and screens. Empty-hand use, edge-triggered redstone, waterlogging, rotated open models and matching collisions. Requires Grand Workshop 0.8.0-dev.1+, Fabric API 0.160.5+26.3, Fabric Loader 0.19.5+ and Java 25+. Verified with all expansions and independently; distinct-process restart checked 64 saved gate configurations and fresh client states. Uses original 16x16 Grand Workshop textures with 16+ visible colours. These are one-block pedestrian barriers without vanilla fence connection or invisible 1.5-block collision.
