How the Iran Tension Meter is set, what the event timeline means, and what this is not.

The score (0–100)

Score bands

Contiguous Amb Affairs bands. Labels are ours — not a U.S. government threat advisory. Ranges are provisional until locked.

BandRangeMeaning (editorial)
Calm0–19Open reporting looks routine; little unusual Iran-related tension.
Watchful20–44Worth closer reading; some open signals above routine, without a sustained step-up.
Elevated45–74Amb Affairs band only: tension clearly above routine in open sources; heightened editorial attention. Not a DHS / NTAS / government alert level — we reuse a plain English word for our own mid–high band.
Severe75–89Sustained high tension in open reporting; serious, ongoing indicators.
Critical90–100Extreme open-source tension reading on this scale.

What this is not

DisclaimerThe Iran Tension Meter reflects human-only editorial judgment by Amb Affairs, drawn from open sources and trusted press. It is not live intelligence, not a U.S. government threat assessment, not a probability of war or forecast, not a government or market product, and not investment advice.
