A Trace Is Not Authority.
A trace is the richest record we have of an agent run — every span, every tool call, every hop. And it still answers the wrong question.
A trace tells you what happened. Authority decides whether it was permitted to.
What a trace gives you
A trace reconstructs the run — precisely, span by span.
- The ordered chain of tool calls and sub-agent hops.
- Timing, inputs, and outputs at each step.
- A debuggable path from prompt to final action.
For debugging and forensics this is invaluable. But a trace is a description of events, and a description carries no verdict.
Where it stops
A trace records that the action occurred; it holds no grant that says it was allowed.
Read a trace end to end and you can see the agent called the transfer tool. You cannot see whether the principal had delegated that authority, whether the purpose matched, or whether the scope had already expired. The trace is complete about mechanics and empty about permission — and an auditor asking "who authorised this?" gets no answer from a span.
- It captures the call; it never captured the right to make it.
- It is produced by the run, so it inherits whatever the run assumed.
- A perfect trace of an unauthorised action is still an unauthorised action.
The line
Authority is a decision taken before the call and sealed independently of it.
KYE Protocol™ evaluates the request against the delegated authority the principal holds and returns an admit-or-deny verdict at the boundary, then binds it into a replay-verifiable Evidence Pack™ that stands on its own — reproducible from public keys, not from the agent's own logs. That is Authority Finality™: the permission is settled and provable, separate from the story the run tells about itself.
Honest scope
KYE Protocol™ proves authority, not correctness.
It will not tell you the trace was bug-free or the outputs sound — keep your tracing for that. What it adds is the missing verdict: whether the actor was authorised to take the action, provable long after the spans have rolled off. Keep the trace. Add the proof.
A trace tells you what happened. Authority decides whether it was permitted to.
