Panorama + grid-frequency hum = a forgery cost that is multiplicative, not additive.
A panorama is usually treated as a wide photograph — a luxury of extra width. PanoVR treats the width as evidence. Preserve the whole strip instead of a crop, bind it to the one signal in the room that nobody controls — the electrical grid's frequency — and you get a record whose forgery cost is not additive but multiplicative. What follows is the case for that idea, in six parts. Prefer to listen? A narrated two-officer debrief runs alongside the text.
