## What this file is

A downloadable record of converting a three-file week to CSV first versus picking the file whose grain already matches the ask. It is **not** a named-logo customer case, a vendor bake-off, or a Nature / ACM / ITU experiment.

## Four-step method (reproducible)

1. Register the Parquet, JSON, and CSV siblings, format, and owner. Sanitize first.
2. Profile types, nests, and header tokens on each copy.
3. Ask one goal: return rate by SKU, denominator = orders, on one winner.
4. Open which path was read and row counts. Name the winner. Re-ask from a clean seat.

## Source and goal

| Field | Value |
|---|---|
| Sources | One week as a 4.2-million-row Parquet, a 180,000-event JSON nest, and a 40-column CSV email |
| Standing goal | Return rate by SKU, denominator = orders |
| Contrast | Pick by habit (CSV first) vs pick by grain |

## Results

| Retrieval state | Parquet typed orders | JSON explode refused | Winner named |
|---|---|---|---|
| Pick by habit (CSV first) | 0 | 0 | 0 |
| Pick by grain | 1 | 1 | 1 |

Wall-clock for the successful grain rerun: 10 minutes (warehouse time excluded). The clock started when the operator opened the standing goal and ended when all three files sat side by side with the winner note open.

## What you may cite

- Artifact counts 0/0/0 → 1/1/1, one week as Parquet + JSON + CSV on this run, ~10 min wall-clock, run ID

## What you may not claim

- Customer uplift %, a faster conversion, official EEAT score, named-logo case, or that Nature / ACM / ITU / Gartner / WAIC scored this run
