E.17.1:12.1 - Resolvable annex references for thin bundles

An ordinary project family designator may be accompanied by references that resolve under the applicable source or reference scheme to exact annex assets. Each reference states its local role—such as lexical, bridge, movePublication, examples, optional sota, or optional pilotTrace. Neither the field spelling nor the role value creates a new reference kind, manifest entity, or typed annex asset. This keeps the declaration claim block thin while allowing A.16 move-publication notes, lexical material, Bridge material, and examples to remain explicit rather than folded into the core family claim.
