- fix: edge-targeted fragment and "insert as optional group" picks from the
add-step dialog now splice the inserted subgraph into the targeted edge
(entries inherit the original routing condition, exits feed the old
target, subgraph moves into the source's column band) instead of dropping
disconnected fixed-position nodes (Greptile P1).
- feat: the lifecycle warnings banner is now a one-line collapsible
disclosure (count summary, details on expand) so it no longer dominates
the editor header.
