36 families of urban signals form a living membrane around the city. Every input is normalized, classified by criticality, signed and timestamped.
Median latency 1.4 seconds · Ed25519 audit · seven-year retention. Without a valid API key, the category stays honest: "not-configured", never a silent mock.
Energy, mobility, climate, satellite flow continuously. Aviation, seismic, civil defense only speak when it matters. The membrane listens, normalizes, judges, signs. Every category is clickable, every signature verifiable.
From Fajr to the distant tremor, here is what the city produces as signals. The membrane captures them, transforms them, transmits them. Everything is traced. Everything is replayable.
The city wakes before the sun. NEXUS-URBAN knows the prayer time from the Hijri tabular calendar and the Umm al-Qura convention. Thirty-two minutes before Fajr, a signal crosses the membrane.
The building prepares to welcome its faithful. Comfort reached at Fajr+5min. No waste. -8% on the monthly bill.
From the daily pulse of energy to the rare alerts of civil defense, every family of signals has its page in the control room — declared sensors, live latency, last update, replay.
