Room-by-Room Vulnerability Report
Every room assessed. Every hazard documented. Prioritized by life-safety risk, not aesthetic preference.

Vulnerability Score
A single number (0–100) summarizing your property's seismic exposure. Recalculated after each remediation milestone.
Benchmarked against USGS ShakeMap for your zip code

Ranked list of interventions by urgency and cost. Not a generic checklist — specific to your structure, your soil zone, your fault proximity.
