Model Drift Is a Governance Event

When model behaviour changes, permissions and approved uses may no longer produce the same risk.

The answer

Drift is treated as a quality metric. In private workflows it can alter refusal, disclosure and action. Monitor consequence-focused tests and suspend affected workflows when behaviour crosses tolerance.

Drift is treated as a quality metric.

Where this breaks

In private workflows it can alter refusal, disclosure and action.

The operating move

Monitor consequence-focused tests and suspend affected workflows when behaviour crosses tolerance.

Value object — The operational card

- Critical behaviour

- Baseline result

- Tolerance

- Suspension owner

The test

Run stable tests on a schedule. A material unexplained change should trigger governance, not prompt tweaking.
