Thane cell 4970000009 → Thane cell 4970000008

The free-flow road distance and duration between these two MH-36 locality cells, with a stability-certified band of near-equal alternatives. Free-flow only — congestion is the separate Ola witness, never folded in. A genuinely disconnected pair is reported honestly as unreachable, never as an infinite or zero distance.

Reachability is three-way honest

Distance is the free-flow shortest path; the engine serves a stability-certified band rather than a single brittle arrow. free-flow (Σ + road-class speeds); traffic-ETA is the separate Ola witness, never folded in (D9)
