russell@unturf.com	1dee074618	kafka-0009: GraphGraceSearchUtil diamond recursion O(2^D) → O(N); count 621→622 ... findAndVerifyWindowGrace() recurses over parent GraphNodes without a visited accumulator. Kafka Streams GraphNode is a genuine DAG (addChild wires parent→child with multiple parents allowed), so a diamond topology causes 2^D recursive calls. Fix: thread an IdentityHashMap<GraphNode,Long> memo through recursion; memoize on first visit, return cached result on revisit. 8/8 unit tests PASS; D=10 defect count=3071 vs patched O(N). Diamond-recursion CLEAN markers added for: flink, neo4j, janusgraph, tinkerpop, dgraph, zookeeper, storm, ant, gradle, graal, eclipse-jdt, exposed, intellij, kotlin, scala3, hibernate-0007 (prior session work now committed).	2026-03-29 16:59:50 -04:00
