Economic corridors

Pollution follows freight and wind, not municipal boundaries — the Amritsar–Kolkata spine alone crosses seven states. Each corridor gets a daily bulletin in a versioned, self-describing format that any state agency can consume over plain HTTP, without adopting our database, our models, or our code.

Historical case study, not live — satellite/fire coverage here is the archived Oct–Nov 2025 stubble-burning season. City-level AQI elsewhere in VAYU is live; extending this corridor view to a live feed needs a standing daily ingestion job, which isn't running yet.
