Research direction

Start with the linked TODO in kernel-src/io/iovec.c at line 10 and inspect how iovec sizes are accumulated. Add a check for size overflow, then verify that oversized totals are rejected while valid sizes still work; the issue does not name a test, so first look for existing iovec tests or callers.
