Quetzal AOI Briefing turns live seismic telemetry into a short, verifiable briefing about where closer observation is warranted. One continuous run fetches the live feed, ranks 2-degree geographic cells by total radiated energy (Gutenberg-Choy relation), and takes the highest-energy cell as the area of interest. Its polygon and centroid are computed locally; magnitude, location, and event count are labeled measured. A hosted SAM segmentation of a satellite crop inside the area is validated and labeled COMPUTED MASK. Muse Spark then writes exactly two sentences in forecast language from the receipted numbers only, and a briefing validator checks the text before it is shown.

Every number carries a label — measured, computed, or inferred — and a receipt. On the November 3 shoot-day run: 200 events, 61 cells ranked, area of interest AOI-2N--76E, magnitude 5.4, computed energy 7,943,282,347,242.8545 joules, Spark request chatcmpl-01a1a2d6-02b7-75d6-9b48-1024320e22e0, validator 0 failures. The fixed seven-step spine passed 7/7 with fail-closed gates. node test/check.mjs passes, and the Python GIS export suite passes 22/22.

This is a forecast-hotspot briefing, never an earthquake prediction. The Quetzal geophysics system underneath predates the hackathon; the briefing pipeline, label and receipt gates, SAM bridge, GIS export, skill agents, and checks were built during the event, October 26 – November 4, 2026.
