Battery nudge:
- lib/batteryPlan: project SoC through the planned stops using current
Tesla battery (or 80% default), 85% of rated range, and conservative
per-stop charge rates (Supercharger 1.5%/min, dest charger 0.4%/min).
- LegRow shows "arrive X%" plus a tone (red/amber/transparent) and a
TIGHT / WON'T REACH chip if the projected arrival is below 15%/5%.
- Top-of-itinerary banner when any leg is danger or warning, naming the
current SoC source (live Tesla vs assumed 80%).
PWA / offline:
- vite-plugin-pwa with autoUpdate strategy; ServiceWorker registered in
main.tsx (prod-only).
- Workbox cache strategies:
map tiles CacheFirst, 30 days, 800 entries
nominatim/OSRM NetworkFirst with cached fallback
/api/* NetworkFirst, short TTL, last response stays usable
- App shell precached so the planner renders offline; navigateFallback
ensures deep links serve index.html without a network round trip.
- manifest.webmanifest + theme-color + favicon.svg (replaces dead
/tesla-icon.svg reference). Installable to home screen.
- Sonner toasts on offline-ready and update-available.
- Proactive Grok integration (xAI API + local CLI fallback)
- Real road routing via OSRM (no more bird's-eye lines)
- Heavy structured logging for fast iteration
- Strong sanitization + geocoding + ErrorBoundary (no black screens)
- Playwright E2E tests (API diagnostic + full UI flow)
- scripts/dev.sh for one-command startup
- Clean .env.example + documentation
This is a stable checkpoint before further prompt/UI refinement.
