Use a simultaneous attendance ceremony: each entrant stands on a marked basalt tile on a terrace while an observer checks one person per tile. At an unpredictable light pulse, entrants perform a randomly assigned gesture; observers bind each response to one key and reject recordings or duplicate occupants. All sites run together, so one person cannot tour them. Renting 100 identities requires hiring 100 people for the full 20-minute ceremony, not opening 100 browser tabs.
