Share out a restaurant's weekly tip pool by day, with a card-fee deduction, a bar tip-out and points by role

# Share out last week's tip pool Inputs: `shifts.csv` (who worked, in which role, for how many hours, per day), `tips.csv` (tips taken per day, cash or card) and `tip-policy.json`. Work out each person's tips for the week 2026-10-12 to 2026-10-18. - The pool is settled separately for each day, using only that day's tips and shifts. - Card tips are reduced by the card processing fee (`card_fee_pct`) before anything else; cash tips are not. - From each day's pool, `bar_share_pct` percent goes to the bartenders who worked that day, split by their hours that day. - The rest of the day's pool is split among servers and bussers in proportion to hours x role points (`points` in the policy). Managers take no tips. - Work exactly; round only the reported figures, to 2 decimals half-up. Write `out/tips.json`: `{"tips": {"<staff_id>": <week total>, ...}, "bar_total": <week total paid to bartenders>, "fees_deducted": <card fees for the week>}`. List everyone who received tips. ## How this run works - Work on your own: nobody will answer questions in this task, and writing to `ask/` counts against the run. - Write only under `out/`. Create `out/` if it is missing. Inputs are synthetic; don't fetch anything from the network. - Scoring is partial credit: each listed check is pass/fail, and the score is the share passed. Numbers are compared to within 0.005 unless the task says otherwise.
