   arrays now retain capacity and reset only touched entries, but bitsets
   still span previously allocated node IDs. Scheduling a newly loaded
   object should cost only for that graph and any affected existing nodes.
-- Reduce repeated scans of all calls and unloaded function summaries in
-  `StopCUNode.compute()`. Review its phase-dependent escape normalization and
-  reliance on the previous result before changing propagation.
