# task_0010

**Benchmark:** crypto-accounting-bench
**Task type:** complete journal entry from transaction evidence
**Organization:** Halden Labs (synthetic)
**Chart of accounts:** 569 accounts

## What you must do

One crypto transaction is described in `input.json` (and rendered for a model in
`prompt.md`), together with the complete chart of accounts of the organization
that recorded it. Infer the **complete journal entry that organization actually
recorded** - every line, its ledger account, its Debit/Credit side and its
base-currency amount - plus the transaction's asset quantity.

This is a reproduction task, not a best-practice task: the answer is the entry in
that organization's ledger, not the entry you would consider ideal.

## What you are given

| File | Contents |
|---|---|
| `input.json` | structured public evidence + the organization's chart of accounts |
| `prompt.md` | the same evidence rendered as a ready-to-send model prompt |
| `expected_answer.json` | the graded answer (do not show this to the model) |

## Answer format

```json
{
  "journalEntry": {
    "lines": [
      {
        "ledgerAccountName": "<exact ledgerAccountName from the supplied chart>",
        "drCr": "Debit | Credit",
        "amountBase": "<decimal string, exactly 2 decimal places>",
        "currency": "CHF"
      }
    ]
  },
  "assetQuantity": "<the transaction's asset quantity, full precision, decimal string>"
}
```

## Grading

This task is scored against the weighted binary criteria in
`expected_answer.json` -> `rubric`. A task passes at a total weight of
85% or above. See `../../README.md` for the full evaluation protocol.
