isMappedSurface

Whether a body's surface comes from a shipped map rather than from the seed.

The terrain milestone's carve-out is mechanical rather than a list: a body with a vendored texture set keeps the rendering path it has, and the new pipeline owns everything else. appearance.texture is the key that decides it, and it is already the key the host resolves against the manifest, so there is nothing to keep in step.

It says nothing about the body's terrain, which has always been seeded on every body in the game including the mapped ones — see the note in design/plans/terrain.md § 1 about what the version bump moves.
