Use case 02 of 03 path & jurisdiction assurance
Prove the traffic took the path you prescribed.
Through inspection, inside the border. This is the failure encryption, mTLS and endpoint telemetry all wave through — and the same mechanism answers tenant isolation.

What we move: per-SID counters are unsampled, so “no undeclared segment was ever executed” becomes a provable negative — at any volume, including the low volume an attack actually has.
0100 the gap
Encryption proves who. It never proves where.
mTLS tells you the two ends were who they claimed. It says nothing about the route between them — which country the packet crossed, which appliance saw it, whether it left the tenant at all.
Classic routing is emergent: the path is observed after the fact, never declared, with no artifact to check against. There is nothing to compare, so nobody compares.
With a segment list, comparison stops being interpretation and becomes a set operation.
The SID list is the declared path, written into the packet: explicit, diffable, machine-readable. Per-segment counters then say whether it was executed — not whether an alert fired.
0200 the mechanism
One flow. One artifact. Three witnesses.
Each source is used only for what it can prove: counters for execution, probes for reachability, flow records for classification. The verdict is the intersection, not any one of them alone.
A denied probe is a security event, never a candidate rule.
