Center the operator's incident workflow
A field-safety interface is useful only when a person can move from a signal to source context, review, status, and a site-specific next action. A detection label by itself is not an operating process.
Keep categories distinct before aggregation
PPE, gas, fire, vehicle, and zone events carry different evidence and escalation requirements. Category views preserve those boundaries while the overview gives one entry point.
Use synthetic data for public inspection
A reviewable public prototype can demonstrate interface and workflow decisions without exposing worker identities, customer sites, private camera feeds, credentials, or incident history.
State what the prototype cannot prove
A demo can support product and workflow design claims. It cannot support claims about live integration, detector quality, alert latency, adoption, safety performance, or business value without production evidence.
