The Light Leaves a Mark
Optical Watermark · Sideband · Non-Repudiable
Every authorised pulse train that passes through the IBA-Pulse MZI gate leaves a non-repudiable optical watermark via weak sideband modulation. WitnessBound captures that mark, hashes it, and chains it forever. The light itself is the audit trail.
Optical Watermark Receipt
When the MZI Gate Fires,
WitnessBound Records It
The Physics Receipt for an IBA-Pulse enforcement event. The dB extinction measurement is physically unique — the energy dissipated by destructive interference cannot be replicated in software.
