/**
 * The "next generation" of `bulk-member.tsx`, for the bulk-operations drill:
 * the `--retarget` source whose computed identity the survey stamps onto
 * member rows, and which the retarget then moves them to. The only difference
 * from generation one is the field a retarget would change.
 *
 * It exports the same pattern twice. A module's identity is its closure's, so
 * `Member` and `MemberAlias` share one identity and differ only in symbol —
 * which is what lets the drill move a piece to a reference whose identity
 * half matches a plan row's target while its symbol half does not, and hold
 * the classification to comparing both.
