Contracts for:

• PluginManifest (plugin-owned)
• ToolManifest (product-owned)

This package is intentionally small and stable; it is consumed by all frontends.

Composer Surface/Material Contract

Manifest-backed Composer tools use Geometry-owned surfaces:

• Geometry emits final material surface ids on renderable meshes.
• The plugin manifest publishes those ids in top-level surfaceContract.surfaces[].
• Material baselines are optional; declared surfaces without tool bindings render with Composer's shared architectural-white startup material.
• When a material baseline intentionally overrides a surface, it binds appearances through baselines.materials[].materials.surfaces.<surfaceId>.
• Every materials.surfaces key must match a declared surfaceContract.surfaces[].id.

Removed lanes are rejected rather than interpreted:

• materials.walls
• materials.floor
• materials.ceiling
• materials.slots
• surfaceMappings[]
• surfaceTypes[]
• tagging.surfaceKey

parentId on a surface definition is taxonomy metadata only. It must not be used to recover or inherit a material binding.
