"## Mini Case\n",
"\n",
"\n",
" A recurring anti-pattern in quantum notebooks is the 'works for my secret' builder. It runs for one hand-picked example, but it is too opaque or too brittle to support variation. That anti-pattern is especially dangerous in a module like Bernstein-Vazirani because the whole point is that a clean family builder should exist. The problems notebook is therefore asking for something stronger than one successful run. It is asking whether your explanation survives secret changes, interface changes, and review pressure.\n"

"## What These Questions Are Really Testing\n",
"\n",
"The multiple-choice format is only the surface. Underneath it, the notebook is testing whether your explanation can survive small shifts in phrasing, emphasis, and review context. If your understanding is robust, the wording can change and the same mechanism will still come into focus. If your understanding is fragile, the wording change will tempt you back into vague or prestige-based answers. That is why these problems matter.\n"

For example, saying that a circuit uses superposition or interference may be accurate, yet still fail to identify what role a specific block is playing in the present design. The goal of the problems notebook is to eliminate that kind of vague correctness and replace it with circuit-specific explanation.\n"
