006 raw fields stay separate

// The same raw material in two compounds is not a shared identity. These two
// `health: f32` fields are spelled the same way, but no terminal names them
// and neither one can prove sameness. Each proto therefore gets its own
// registry entry, its own `List_` container, and its own rows. A future layout
// layer may only merge what a shared terminal proves identical; this pin
// guards the declaration half of that rule.
