• Medium, security/API surface: src_cpp/main.cpp:12 exports createArrowCSRTestData from the production native
  addon. That is test fixture code shipped in the runtime binary, returning unmanaged native pointer-like
  Externals. Even if it is not in the public .d.ts, it is still part of the native module surface and gives
  consumers a native allocation helper that only exists for tests. This should be behind a test-only build flag,
  moved into a separate test addon, or avoided.

• Medium, DoS/memory-safety risk: src_js/connection.js:428 validates dstColName in CSR mode but does not validate indptrArraysPtr or numIndptrArrays. Native then uses Uint32Value() at src_cpp/node_connection.cpp:293 and src_cpp/node_connection.cpp:295. Values like -1 can wrap to a huge unsigned count, and TakeArrowArrays reserves/reads that many arrays from a pointer. Validate both counts as positive safe integers in JS and add native range/type checks too.
