Auto-Label Simulation does not simulate your rules exactly

When you’re building an auto-labeling rule and run a simulation, don’t expect it to fully follow your rule. Let me explain.
It doesn’t evaluate everything. For example, if your rule says a document must match at least four regex patterns to count as a positive find, the simulation might treat a single match as a positive.
Yeah, that’s frustrating.
Here’s what works better:

Build your Sensitive Information Type (SIT) and test it against individual documents first.
Then create a policy that targets a small subset of data.
Run the simulation, then turn on the policy.
Check the results in Activity Explorer, which shows real production activity.

Why can’t the simulation just run the full rule? Good question—we all wish it did.
