Slice 7 of the #319 retirement. aura-runner's blueprint_sweep_family / blueprint_walkforward_family / blueprint_mc_family lost their only production callers with the quintet and are gone (family.rs 889 -> 199 lines) together with their zero-caller helpers; reproduce's live inputs (DataSource, showcase/walkforward sources) stay. Coverage was ported first: member-computation identity + family-shared topology_hash now pin through a campaign-document twin in tests/exec.rs, reproduce's multi-member and MC-seed-label branches re-mint their fixtures directly. The CLI-side topology_hash helper goes with them — its keep-rationale was disproven (the record line's hash is computed in the runner's member machinery; minuted on the issue) — and c28_layering's file list drops the stale verb_sugar entry. The synthetic per-seed MC family remains an intentional retirement casualty, recorded in the test dispositions. refs #319
