Concerns: No runtime smoke test asserting that libevent can be linked/used (e.g., building a tiny test program) — only header/lib existence checks are performed., Final image CMD is a bash shell, which is fine for debugging but not representative of a library container's typical usage; consider removing or replacing with a minimal entrypoint.
Smoke [PASS]: test -f /usr/local/include/event2/event.h
Smoke [PASS]: ls /usr/local/lib | grep -E '^libevent' >/dev/null 2>&1
