G.6:4.5 - Refresh and source return

Reopen the smallest affected PathId, PathSliceId, node projection, or relation-edge projection when any cited object, direct relation, governor, source, bridge, representation correspondence, edition, policy, time window, currentness result, or reliance boundary changes.

If the direct relation no longer obtains or its proof becomes unavailable, remove it from the relied-on path or mark the exact unresolved gap. Do not preserve the edge from graph history, infer a replacement relation, rerun unrelated paths, or certify a new downstream result through refresh alone.
