  "result": "I wrote `out/revenue.json` with Q3 2026 net revenue of $365,738.60 across four regions. South is the top region at $118,782.62.\n\n```json\n{\"by_region\": {\"East\": 84414.82, \"North\": 85018.25, \"South\": 118782.62, \"West\": 77522.91}, \"total_usd\": 365738.6, \"top_region\": \"South\", \"refunds_usd\": 51672.95, \"duplicate_rows_dropped\": 381}\n```\n\nChoices I made that the task left open:\n\n- **Amount units.** The export files use three amount columns. I read `amount_cents` as cents, `amount` as currency units, and `amount_k` as thousands of currency units (so `0.51710` is 517.10). The magnitudes are consistent with this, but the `amount_k` reading is an inference.\n- **Deduplication.** 381 `txn_id`s appear in two weekly files. All duplicates were identical and every one is dated in Q3, so `duplicate_rows_dropped` is 381 with no ambiguity about out-of-quarter rows.\n- **Exclusions.** I dropped 81 rows dated outside July\u2013September, 73 void rows, and 130 rows from ST134, which is in `training` status. Only the nine trading stores feed the regional totals and `refunds_usd`.\n- **FX and rounding.** Each transaction is converted at its own month's rate for its store's currency. Everything is summed exactly and rounded half-up to cents only at the end.\n\nThe calculation script is at `/tmp/rev/calc.py`, outside `out/`.",
