+# CLEAN: deno
+
+Scanned 2026-03-30. No actionable CWE-407 defects found.
+
+The Deno codebase uses correct data structures throughout:
+- `HashSet` for deduplication and membership tests (module_loader.rs, permissions/lib.rs, etc.)
+- `BTreeSet` for sorted membership (cli/util/extract.rs)
+- `HashMap`/`BTreeMap` for O(1) keyed lookups
+- Fixed-size array literals only for small constant-size checks
+
+No `Vec.contains()` patterns found in performance-critical loops.
