FireLens is a citizen-facing California wildfire decision tool that turns typically opaque, expert or industry-only fire data into a plain-language risk read for any ZIP code. It separates  two  drivers of risk: the weather attributed risk of fire, and built exposure for the implications of a fire. Californians see not just whether they're at risk, but why, and the next steps to take. Every figure traces to an authoritative public source: the  Fire Weather Index (ECMWF/Copernicus, from ERA5), FEMA's National Risk Index, and US Forest Service LANDFIRE fuel models, grounded in 85 years of fire-weather record. An Opus-powered agent answers free-form questions by investigating with real data tools, and will refuse to fabricate when the data can't answer. It's a decision tool: legible, sourced, and honest by construction.
