# 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.
