# BI Detective

Standalone static-site exercise for a data-literacy lecture (ХАРТІЯ × KSE GBS, 9 травня 2026).

VP message says brigade efficiency went 62% → 71% over a month. Player has 4 dashboard tabs and 9 multiple-choice quizzes to figure out *why* — and whether the headline number actually means what it looks like (mission-mix-shift / Simpson's paradox).

Synthetic dataset of 8 540 ops; UI in Ukrainian; no backend.

## Run locally

Serve the directory with any static HTTP server, e.g.:

```
python3 -m http.server 8000
```

Then open `http://localhost:8000`.

## Regenerate the dataset

```
python3 generate_data.py
```

Rewrites `game_data.js` (and `raw_facts.csv`). Headline calibrates to ≈ 62% → 71%; per-category success rates rock-stable across runs.
