Frontend

Next.js UI for the Maintenance Tool. No local data, no API routes -- reads everything from the backend on port 4000.

Setup

Start the backend first, then:

npm install
npm run dev      # http://localhost:3000

Optional .env.local:

NEXT_PUBLIC_BACKEND_URL=http://localhost:4000

Dashboard -- fleet health KPIs, active alerts, equipment list, maintenance priorities, sensor trend watchlist
Equipment -- browse all assets, drill into individual asset with sensors, history, risk, spares
AI Investigation -- chat with the maintenance agent, see tool steps, evidence panel, create plans and reports
Planner -- view and manage generated maintenance plans
Predictions -- failure predictions grouped by urgency band
Knowledge -- upload data files, view indexed documents and ingestion history
Reports -- generated investigation reports + digital logbook with search/filter
