# Spend Report Package — Completion Report

## Implemented work

- Split the former `src/report.js` module into the public `src/reports` package:
  `parse.js`, `aggregate.js`, and `format.js` hold the individual functions,
  while `index.js` is the sole caller-facing entry point and retains
  `generateReport`'s parse → aggregate → format behavior.
- Updated `test/report.test.js` to import from `src/reports/index.js`.
- Added the exported `formatSummaryCsv(totals)` formatter. It produces the
  `category,amount` header followed by alphabetically sorted category/amount
  rows, and is re-exported from `src/reports/index.js`.
- Added public-interface coverage for CSV header, values, and sort order.

## Verification

Command run:

```sh
npm test
```

Result: 6 tests passed, 0 failed (exit code 0).

## Concerns
