## What this file is

A downloadable record of opening a second warehouse “for AI” versus authorizing the billed cloud account in place. It is **not** a named-logo customer case, a vendor bake-off, or an IETF / Snowflake / AWS experiment.

## Four-step method (reproducible)

1. Name the account, region, and instance already on the bill.
2. Create a SELECT-only role. Revoke leftover write. Prove a write fails.
3. Ask one goal: Q2 refund rate by channel, paid orders as the denominator.
4. Inspect SQL. Confirm SELECT-only. Hand the dated pack to a colleague.

## Source and goal

| Field | Value |
|---|---|
| Sources | Existing reporting replica on the billed account; 11 schemas; ~3.4 million paid-order rows |
| Standing goal | Q2 refund rate by channel, paid orders as denominator |
| Contrast | Recreate-first twin vs authorize-in-place |

## Results

| Retrieval state | Account named | Write revoked | SQL inspectable |
|---|---|---|---|
| Recreate-first twin | 0 | 0 | 0 |
| Authorize-in-place | 1 | 1 | 1 |

Wall-clock for the successful authorize rerun: 10 minutes (warehouse provisioning excluded). The clock started when the operator opened the standing goal and ended when the named account, the failed write, and the inspectable SQL sat side by side.

## What you may cite

- Artifact counts 0/0/0 → 1/1/1, 11 schemas + ~3.4M paid-order rows on this run, ~10 min wall-clock, run ID

## What you may not claim

- Customer uplift %, a cheaper twin, official EEAT score, named-logo case, or that IETF / Snowflake / AWS / DataCite / W3C / ISO / Gartner / WAIC scored this run
