## What this file is

A downloadable record of flattening a nested event export first versus asking nested objects in place. It is **not** a named-logo customer case, a vendor bake-off, or an IMF / BIS / Eurostat experiment.

## Four-step method (reproducible)

1. Register the fourteen daily JSON files, stream-or-object shape, and owner. Sanitize first.
2. Profile root keys, array lengths, null vs missing, and type clashes. Note day-11 `payload.refund`.
3. Ask one goal: failed-item rate by SKU for the last seven files, with item rows in the denominator.
4. Open the path that was read and parent versus child counts. Re-ask the same goal from a clean seat.

## Source and goal

| Field | Value |
|---|---|
| Sources | Fourteen daily JSON files, about 180,000 events and 610,000 `payload.items[]` rows |
| Standing goal | Failed-item rate by SKU for the last seven files, excluding one-day-only SKUs |
| Contrast | Flatten first vs ask nested objects |

## Results

| Retrieval state | Day-11 nest profiled | Parent-child counts opened | Same-day re-ask possible |
|---|---|---|---|
| Flatten first | 0 | 0 | 0 |
| Ask nested objects | 1 | 1 | 1 |

Wall-clock for the successful nested rerun: 10 minutes (warehouse time excluded). The clock started when the operator opened the standing goal and ended when both packs sat side by side with the day-11 nest note and the parent-child counts open.

## What you may cite

- Artifact counts 0/0/0 → 1/1/1, 14 daily files + ~180k events / ~610k item rows on this run, ~10 min wall-clock, run ID

## What you may not claim

- Customer uplift %, a faster flatten, official EEAT score, named-logo case, or that IMF / BIS / Eurostat / Gartner / WAIC scored this run
