+
+Scanned 2026-03-29 for CWE-407 (algorithmic complexity).

+- SingleSignOnAuthenticationMechanism — CLEAN: guarded with `seenSessionManagers.add(manager)` return check
+- Predicate parser, handler chains — CLEAN: HashMap-based dispatch, no linear scans in hot paths
+
+**Result: No actionable CWE-407 defects.**
