…w, drop global Live Tracking Make the fleet views cheaper against DIMO APIs (~500-vehicle tenants) and faster to paint on cold load: - FleetCache now writes through to IndexedDB (idb-keyval, one snapshot per tenant, 24h max age). Map and list views paint instantly from the last snapshot on a hard reload, then always revalidate against /vehicles — paint-only, server wins; markers for vehicles no longer in the fleet are pruned after a persisted paint. - fleet-list-view drops its private always-pull-everything location fan-out for the shared seedLocationsFromDb + fetchFleetLocations, so it now respects the 5-min locationPulledAt freshness window instead of re-pulling every vehicle on each visit. - Remove the global "Live Tracking" button (top bar + map legend): it force- refreshed the entire fleet every 60s, bypassing both the freshness window and the backend 45s cache. Per-vehicle live tracking stays via the quick-view "Real-time · 20s" toggle. Live-verified against the 430-vehicle fleet: zero /telemetry/locations on reload within the window, partial refresh re-pulls only stale vehicles, force refresh still re-pulls all, expired snapshots ignored gracefully.

The committed bundle lost the two eslint-disable comments during a local stash round-trip, tripping CI's localize drift check. Regenerated via npm run localize; no message changes.

Why
For a ~500-vehicle tenant the fleet views were generating avoidable DIMO telemetry load, and cold loads waited a full network round-trip before painting anything:
locationPulledAtfreshness window and the backend 45s cache (~500 telemetry queries/min while enabled)./vehiclesreturned.What
FleetCache→ IndexedDB write-through (idb-keyval, keyfleet:${tenantId}, 24h max age). Map and list views paint instantly from the last snapshot on cold load, then always revalidate:/vehiclesstill fetched, stale-only fan-out still runs, server data replaces the paint. Markers are pruned after a persisted paint so removed vehicles don't ghost.invalidate()also deletes the persisted entry.seedLocationsFromDb+fetchFleetLocations), so it respects the 5-min window and streams stale-only — identical backend load profile to the map view.locationPulledAt, shared across users/devices — deliberately not moved client-side).LOCATION_REFRESH_PLAN.mdstatus updated (was still "pre-implementation").Verification (live, 430-vehicle James Fleet tenant)
