ROUTE_STALE_AFTER_NODE_MOVE
ROUTE_STALE_AFTER_NODE_MOVE is a geometric warning: an edge still follows a corridor computed before its node moved, so it anchors where the node used to be.
What triggers it. A compaction or alignment pass moved a node after edge routing without re-anchoring the affected edges. Not producible from source alone in normal operation.
How to fix it. No diagram edit reliably clears it; report the reproducing source. If it blocks a task, removing and re-adding the named edge forces a fresh route.
Run am verify diagram.mmd --json, inspect this code, and apply the smallest source or typed mutation that clears it. If it persists after two mechanical attempts, return the warning and ask for human review.
