Presence Layer

Check the object behind the record.

Presence Layer is designed to connect a physical item to its approved origin or identity at the point where a team accepts, transfers or uses it.

Layer prototypes · Controlled validation
For example

Before a critical component enters assembly, a checkpoint could test whether the item matches the protected object the record describes.

How it works

  1. 01

    Define the object

    Agree which item, origin and claim need protection.

  2. 02

    Check at the handoff

    Test the physical item at the relevant checkpoint.

  3. 03

    Decide what happens

    Operations accept, hold, release or investigate.

Go a little deeper

Where a check may help

Manufacturing, controlled custody, service, returns, resale and shared assets. What needs checking depends on the item and its lifecycle.

What must be validated

The connection between the item and its record, resistance to substitution, operating conditions and how the result reaches existing quality or custody systems.
