A different route is not necessarily drift.
Measure adherence to active constraints, rather than similarity to a preferred path.
Compare the obligation
Two agents can choose different tool calls while respecting the same business rule. One might reconcile immediately; another might defer and escalate within its authority. A different permissible path is not automatically a regression.
Track explicit constraints and authorized changes. Do not treat inferred hidden beliefs, text similarity or a changed plan as an authoritative policy.
Ask three separate questions
Session adherence asks whether an active obligation was respected in one execution. Version comparison checks matched tasks under a baseline and a candidate. Production drift asks whether adherence changed across comparable operational cohorts.
A task-mix change, a newly approved exception or a revised policy can change observations without proving deterioration. Keep policy meanings, observation coverage and workload cohorts visible in the comparison.
Unknown stays unknown
Missing observations cannot establish compliance. One well-supported violation can still be useful even when the sample is too small to claim a trend.
Monitoring is not automatic prevention or authority. An alert cannot deploy a new rule, refresh an old certificate or take away permissions without a separately authorized control decision. The vision interaction illustrates these distinctions; production drift remains planned work.
