Resolve one connected lineage and retain its root-to-parent capabilities. Backends validate ancestor identity/membership and refresh all policy metadata inside the same boundary as target validators and typed dispatch; hidden/replaced ancestors reject as NotFound without invocation or effects. Preserve pinned leaf and configured-root capabilities. Covers MR ANCESTOR_VISIBILITY_TOCTOU with HTTP memory and Linux replacement/budget/guard regressions; all T-19 workspace acceptance commands pass (Clippy via Nix shell).
