| # Ecommerce Analytics SQL Evaluation (declared GMV, verified answer key) |
|
|
| An **evalpack**: an evaluation database generated from the answer key, not |
| annotated after the fact. A VLDB 2026 audit found 52.8% of BIRD Mini-Dev |
| answer keys wrong because benchmarks annotate answers onto existing |
| databases; this dataset inverts the order. The declared properties (curves, |
| shares, identities) are the specification, the database is generated to |
| satisfy them exactly, and every shipped question was re-verified by |
| executing its gold SQL against these exact files with DuckDB, an engine |
| that shares no code with the generator. |
|
|
| **12,800 rows** across the tables below. |
|
|
| ## What is in it |
|
|
| Tables: customers (800 rows), orders (12,000 rows). |
|
|
| Monthly GMV is declared (400k rising to 525k) and lands exactly; category |
| shares of GMV (Electronics 40%, Home 25%, Toys 20%, Grocery 15%) hold to the |
| cent inside every month. Every order belongs to a customer who exists and |
| postdates that customer's signup. 43 questions ship: monthly totals, row |
| counts, per-category filtered aggregations, and FK integrity checks. |
|
|
| ## Files |
|
|
| - `tables/*.csv`: the database |
| - `questions.jsonl`: one verified question per line (natural language, |
| gold SQL, expected answer, tags) |
| - `certificate.json`: per-question DuckDB verification plus FK proof |
| - `manifest.json`: spec hash, seed, library versions, dropped candidates |
| - `verify.py`: standalone re-verification (needs only `pip install duckdb`) |
| - `schema.misata.yaml`: the full declaration; regenerate or rotate the pack |
| from it |
|
|
| ## Re-verify in thirty seconds |
|
|
| ```bash |
| pip install duckdb |
| python verify.py |
| ``` |
|
|
| ## Rotate the environment without touching the answer key |
|
|
| ```bash |
| pip install misata |
| misata evalpack --config schema.misata.yaml -o rotated_pack --seed 7 |
| ``` |
|
|
| A new seed replaces the rows; the declared answers stay the answers, so |
| agents cannot memorize the environment. Same version + same schema + same |
| seed reproduces these bytes exactly. |
|

| ## The rest of the shelf |
|
|
| Same idea, other domains, every answer re-verified with DuckDB against the |
| shipped files: |

| If you want ground truth for a regression rather than for SQL, the |
| [machine degradation set](https://huggingface.co/datasets/rasinmuhammed/predictive-maintenance-remaining-useful-life) |
| carries exact remaining useful life on 100 run-to-failure machines. |
