Two issues from the first deploy attempt:
1) Build failure (real): linker errors on s2.cpp's CUDA build —
undefined references to cuMemSetAccess, cuDeviceGet, etc. These
are CUDA Driver API symbols (in libcuda.so), not Runtime API
(libcudart.so). The driver lib is provided by NVIDIA's container
runtime at RUN time, not BUILD time.
Fix: nvidia/cuda:devel images ship a stubs library at
/usr/local/cuda/lib64/stubs/libcuda.so that provides the symbols
for linking but is non-runnable. Adding that path via
LIBRARY_PATH + CMAKE_LIBRARY_PATH lets the linker resolve while
leaving runtime unchanged (real libcuda.so comes from the
driver mount).
2) Verify false positive: the /v1/tts verify step's last command was
`rm -f "$out"` — which always exits 0. This made the shell's
final exit code 0 regardless of whether curl/file/grep succeeded,
so verify reported OK even when nothing was running on host_port.
Fix: `set -e` at top + trap-based cleanup. Failures now propagate;
the rm still runs on either path via EXIT trap.
