  "result": "I wrote `solve.py` (standard library only). Running `python solve.py input.json answer.json` reads `home.json` from the current folder and writes `answer.json` and `home.html`. I ran it on the given home and checked the output by hand. I also ran five random test homes through headless Chrome, with 1 to 20 rooms, up to 200 devices and up to 193 alerts. In every case the page didn't scroll, every tile was at least 40\u00d740 px and on screen, and `#alerts` and every alert row stayed fully on screen. I couldn't run the hidden scoring checks.\n\n**Results for the given home:**\n- **Summary:** 21 online, 5 offline, 1 light on, average temperature 68.9\u00b0F.\n- **10 alerts, in order:**\n  - 2 leaks: d08, then d21.\n  - 5 offline devices: Kitchen first, then Front Porch, then Main Bedroom, following the room order.\n  - 2 temperature drifts: the two Garage thermostats, 64.9 vs 70.0 and 66.9 vs 72.0.\n  - 1 low battery: d02 at 7%.\n- **No unlocked-at-night alerts.** Local time is 19:58, before the 22:00 start of night.\n- **Battery at exactly 20 doesn't alert.** The rule is \"< 20\", so d12 at 20% raises nothing.\n\n**How it works:**\n- **Times:** timestamps are compared as real instants, so the different offsets don't matter.\n- **Rounding:** Celsius conversions and the average use exact decimal arithmetic with half-up rounding, so a value like 18.25\u00b0C comes out as 64.9\u00b0F rather than being skewed by float rounding.\n- **Layout:** the page is 1920\u00d71080. Room panels sit on the left and size themselves to fit: the script picks the largest tile size, from 150 px down to 40 px, at which every room fits. The alert list is on the right and its rows shrink so the whole list always fits on screen. Offline devices and devices with an alert are styled differently.\n- **Static page:** there are no scripts, images, external links or `url()` references, and all names are HTML-escaped.\n\n**Assumptions about inputs the brief doesn't cover:**\n- **Contact open time:** a contact's `open_since` is read from its `state`, or from the device itself if it's not there. The given home has no open contacts, so I couldn't check where this field really lives.\n- **Unlisted rooms:** a device whose room isn't in `rooms` gets that room added at the end.\n- **Very large homes:** if a home were too big to fit even at 40 px tiles, the page falls back to a plain grid of 40 px tiles. None of the test homes needed it.",
