  "result": "I've written `out/payouts.json`, covering all seven properties. Owners are owed **\u00a318,207.59** in total for October 2026. I spot-checked one cross-month booking by hand but haven't verified the rest independently.\n\n| Property | Payout | Tourist tax |\n|---|---|---|\n| The Granary | 3,296.71 | 120.00 |\n| Tide Cottage | 3,159.66 | 86.00 |\n| Curlew Cottage | 2,816.14 | 154.00 |\n| Rookery Barn | 2,594.01 | 150.00 |\n| Bramble End | 2,512.75 | 112.00 |\n| Old Forge | 2,130.85 | 116.00 |\n| Mill Loft | 1,697.47 | 102.00 |\n\nHow the rules were applied:\n- **Cancelled bookings:** the two cancelled ones (BK3789 and BK3777) were left out.\n- **October nights only:** stays that start in September or end in November paid only for their October nights. The check-out date doesn't count as a night.\n- **Cleaning:** the \u00a365 fee was charged only when the check-out date is in October, so stays ending in November weren't charged.\n- **Tourist tax:** the 7-night cap counts from each booking's check-in, even when the stay began in September. For example, Curlew Cottage's booking from 29 September already had two nights before October, so only 5 of its October nights are taxed.\n- **Rounding:** each property's payout and tax were added up unrounded, then rounded half-up to the cent once. The total is the sum of the rounded payouts.\n\nThe script that produced the file is at `/tmp/pay.py`, outside the work folder.",
