Better decisions need the right evidence.
If two physical situations produce the same information, a system cannot reliably tell them apart using that information alone. This report examines what a useful physical observation must add.

Does the available evidence tell the institution something meaningful about the actual person, object or condition behind the request?
The idea in three steps
- 01
Connect the claim to reality
Define the person or object and how it is observed.
- 02
Interpret the evidence
State what the result means within known operating limits.
- 03
Authorise and enforce
Keep the decision and action separate from the observation.
Go a little deeper
The six roles
Binding, observation, evidence, appraisal, authorisation and enforcement. Separating them makes responsibilities and failures easier to examine.
What an assurance claim must specify
The exact claim, operating domain, threat model, freshness, lifecycle state and consequences of error. Confidence only has meaning within those conditions.
The proposed standards direction
PTAS is a prospective research and governance pathway, not an adopted consensus standard or certification programme.
