Muse Spark 1.3 on Find the payout mismatches

Passed in 25s. Attempt 2. Run 20260904T115259Z-muse-spark-1-3-csv-reconcile-2.

Task

Find the payout mismatches

Compare stripe_payouts.csv with bank_deposits.csv.

Each Stripe row names the expected bank deposit after its fee. A matching bank deposit has the same payout id, the expected amount, and a date no more than two calendar days after the payout. Find these problems: a missing deposit, a deposit short by the Stripe fee, a duplicate deposit, a deposit more than two days late, and a bank deposit with no Stripe payout.

Write mismatches.csv with exactly this header:

id,kind,amount

Use the payout id for payout-side problems and the bank deposit id for a bank-only problem. amount should be the missing or extra amount for missing, short, duplicate, and bank-only rows; for a late deposit, use the deposit amount. Use a short plain label in kind.

# Find the payout mismatches

Compare `stripe_payouts.csv` with `bank_deposits.csv`.

Each Stripe row names the expected bank deposit after its fee. A matching bank deposit has the
same payout id, the expected amount, and a date no more than two calendar days after the payout.
Find these problems: a missing deposit, a deposit short by the Stripe fee, a duplicate deposit,
a deposit more than two days late, and a bank deposit with no Stripe payout.

Write `mismatches.csv` with exactly this header:

` ` `csv
id,kind,amount
` ` `

Use the payout id for payout-side problems and the bank deposit id for a bank-only problem.
`amount` should be the missing or extra amount for missing, short, duplicate, and bank-only rows;
for a late deposit, use the deposit amount. Use a short plain label in `kind`.'

Output

Fixing your payout mismatches — comparing Stripe to bank deposits.
I spotted five likely mismatches — now I'll verify the details to finalize the report.
Done. Wrote `mismatches.csv` with 5 rows.
