The fourth backend goes out with the set: WebGPU draws all forty-three golden
scenes, answers the conformance suite, and compiles the engine's shaders through
a GLSL to WGSL pipeline of its own. flutter3d_editor_core and flutter3d_editor_mcp
are first uploads beside it, so an agent can edit a level through the same
commands a person uses.

pad_input and pointer_lock stay on their own line at 0.4.1: their libraries have
not changed since 0.4.0, only a README footer that pointed at a path no package
page can resolve.

flutter3d_game_strategy carries 0.6.0 in the checkout and is not uploaded. Its
stockpile and delivery count were lists of exactly two, one per side, so its
types encoded how many sides a match may have; that is fixed and the package
waits for the rest of its acceptance.
