Make legacy backfill order-insensitive for undirected graphs via pmin/pmax key matching (guards objects saved before weight was stored) summary API (R/summary_methods.R): - Rewrite summary.gg_udependent() to use .summary_skel() returning c("summary.gg_udependent","summary.gg"), consistent with all other summary.gg_*() methods; body carries edges/nodes/threshold lines print guard (R/print_methods.R): - Add NULL-safe provenance fallback in print.gg_udependent() - Replace print.summary.gg_udependent() body with NextMethod() to delegate to print.summary.gg() which renders the skel format Snapshots (tests/testthat/_snaps/): -
