Both were flagged in Wave 17 survey as borderline real defects deferred for follow-up because the fix needed careful design beyond a single-line set hoist. Both shipped now with full bench + ticket + intel. UNDF-1310 symfony-0001 (HIGH) - PropertyAccessor::writeCollection. Doctrine entity collection diff: in_array($item, $collection, true) per item in $previousValue, then in_array($item, $previousValue, true) per item in $collection. O(P*C). Fix: dual lookup (SplObjectStorage for objects + serialize-keyed array for scalars, in_array fallback for resources). Bench: 5.2x at P=C=100, 88x at P=C=2000. UNDF-1311 pyright-0001 (HIGH) - CallHierarchyProvider outgoing/incoming call dedup. _outgoingCalls.find / _incomingCalls.find with composite key (uri, range) walks the list per call expression. O(C^2). Fix: parallel Map<string, entry> keyed by composite serialized form (uri|start.line|start.char|end.line|end.char). Bench: 2.7x at C=100, 22x at C=2000. Total session flagships: 11 (was 9) — 7 CWE-407 + 3 MOAD-0003 + 1 MOAD-0004. Wave 17 borderline backlog now empty. |
