; test_nam_passthrough.csd — smoke test for csound-nam.so: runs 1 second of
; silence through NAMProcess and verifies no crash / no error output.
;
; usage (from the opcode source directory):
;   csound --opcode-lib=build/csound-nam.so test/test_nam_passthrough.csd
;
; expected: Csound starts, runs 1 s, exits cleanly. with a missing or empty
; profiles dir a "no .nam files" message is expected and correct — the
; opcode passthrough is active.
