I cleaned the export according to its brief. All 14 source rows are still there in their original order, and nothing was deleted or merged. Seven rows are clear and seven are flagged with an issue, each with one entry in the exception log. `input.md` was not changed: its checksum is the same before and after.

**What changed:**
- **Original columns:** all kept unchanged. The cleaned values are in new columns next to them.
- **IDs:** stored as text, so leading zeros like `001001` are kept.
- **Dates:** those already in YYYY-MM-DD format were copied to the new date column.
- **Amounts:** `1,250.00` became `1250.00`, and `(45.00)` became `-45.00` because the brief says parentheses mean a refund.
- **Names and cost centers:** the extra spaces around " Riley Chen " were removed, and `ops` became `OPS`.
- **Not filled in:** row 9's date, row 13's amount (`TBC`), row 14's amount (`1.234,50`) and row 10's currency are left blank in the new columns. No unknown amount was set to zero and no currency was guessed.
- **Duplicates and conflicts:** each kind is flagged in its own column. Row 6 is marked as an exact copy of row 5. Rows 7 and 8 share an ID but have different amounts, and both are marked as a conflict.

**Partial totals** (only the clear rows, counting row 5 but not its copy; not a final accounting total; no currency conversion):

| Currency | Rows included | Total |
|---|---|---|
| USD | 1, 2, 4, 5, 11 | 1375.49 |
| EUR | 3, 12 | 420.00 |

Rows 6, 7, 8, 9, 10, 13 and 14 are left out of the totals, and the reason for each is listed in `reconciliation.md`.

**Decisions needed from you:**
1. **Row 6:** is it a double export, or a real second expense?
2. **Rows 7 and 8 (ID 001006):** is the correct amount 120.00 or 140.00, or are these two separate expenses?
3. **Row 9:** is `03/04/2026` 3 April or 4 March?
4. **Row 10:** what currency is the 95.00 in?
5. **Row 13:** what is the invoiced amount?
6. **Row 14:** what is the intended value of `1.234,50` EUR? Reading the comma as a decimal point would give 1234.50, but the brief says the format is unknown.
7. **Combined total:** a single total across USD and EUR would need an approved conversion rate, and none was given.

The totals will change once these are settled. For example, rows 7/8 would add 120.00 or 140.00 USD, and row 9 would add 49.00 USD.

Nothing was sent anywhere or written to any live system.
