  "prompt": "Complete the three tasks below using only the supplied data and rules. Return exactly one JSON object with keys \"appointments\", \"review\", \"cancelled_ids\", \"roi\", and \"revenue\". No Markdown, explanation, extra keys, external research, or messages to anyone. All records are synthetic.\n\nTask 1: Normalize appointments.\nEach timestamp is local time at the explicitly fixed offset UTC+09:00. Validate calendar dates. Convert valid appointments to UTC as YYYY-MM-DDTHH:MM:SSZ. Never infer a missing time. A cancelled record is excluded from appointments and included in cancelled_ids. Put missing-time or invalid-date records in review, with reason exactly \"missing_time\" or \"invalid_date\". When several valid scheduled records share an id, keep the last valid scheduled record in input order. Sort appointments by UTC time ascending, and review/cancelled_ids by id ascending. Preserve id strings. Each appointment must have only id and utc; each review record only id and reason.\nInput, in order:\n{\"id\":\"001\",\"date\":\"2026-01-31\",\"time\":\"23:30\",\"status\":\"scheduled\"}\n{\"id\":\"002\",\"date\":\"2026-02-01\",\"time\":\"00:15\",\"status\":\"scheduled\"}\n{\"id\":\"001\",\"date\":\"2026-01-31\",\"time\":\"23:45\",\"status\":\"scheduled\"}\n{\"id\":\"003\",\"date\":\"2026-02-01\",\"time\":\"09:00\",\"status\":\"cancelled\"}\n{\"id\":\"004\",\"date\":\"2026-02-01\",\"time\":null,\"status\":\"scheduled\"}\n{\"id\":\"005\",\"date\":\"2026-02-30\",\"time\":\"10:00\",\"status\":\"scheduled\"}\n{\"id\":\"006\",\"date\":\"2026-02-01\",\"time\":\"08:00\",\"status\":\"scheduled\"}\n\nTask 2: Calculate a 12-month ROI in JPY.\nInitial setup is 200000 and initial training is 50000. Subscription is 12000 per month for the WHOLE organization. Time saved is 8 hours per month for the WHOLE organization, valued at 2500 JPY/hour. There are 4 employees; do not multiply whole-organization inputs by the employee count. Additional gross profit is 0.\nannual_cost = initial setup + initial training + 12 * monthly subscription.\nannual_benefit = 12 * (monthly hours saved * hourly value + monthly additional gross profit).\nannual_net = annual_benefit - annual_cost.\nroi_percent = annual_net / annual_cost * 100, rounded to 2 decimal places.\npayback_months = (initial setup + initial training) / (monthly benefit - monthly subscription), rounded to 2 decimal places; null if the denominator is not positive.\nReturn roi with exactly annual_cost, annual_benefit, annual_net, roi_percent, payback_months, and benefit_type. Set benefit_type to \"valued_time_not_cash_savings\"; no cash saving has been established.\n\nTask 3: Separate revenue stages.\nThe following events are distinct transactions, not status updates to one transaction. Sum amounts within each stage only. A click is not revenue. Do not add occurred, confirmed, cancelled and paid amounts into one revenue total.\n{\"id\":\"E1\",\"stage\":\"click\",\"amount\":null}\n{\"id\":\"E2\",\"stage\":\"occurred\",\"amount\":1000}\n{\"id\":\"E3\",\"stage\":\"confirmed\",\"amount\":2000}\n{\"id\":\"E4\",\"stage\":\"cancelled\",\"amount\":500}\n{\"id\":\"E5\",\"stage\":\"paid\",\"amount\":1500}\nReturn revenue with exactly click_count, occurred_amount, unpaid_confirmed_amount, cancelled_amount, and received_cash_amount.\n",
