584571a tried to discard the first-attempt error via `_ = err1` to document intent, but zig 0.16 rejects that pattern with "error set is discarded". build failed on the operator's ReleaseFast pipeline and slipped past my local `zig build test` because the test binary is lazy — no test references resolveHostAuthority, so zig never analyzed the function body. `zig build` (the exe) does reach it via frame_worker.processFrame and trips the error immediately. just drop the capture. the comment explaining why only err2 is logged is preserved.
