ServiceEM creates groups with a predictable naming convention, but classification reports require explicit tier metadata. Since groups do not support Custom Security Attributes (CSA), the only automatic classification path is AlternateObjectTierLevelAttributes.
This design adds an optional -UpdateClassificationConfig switch to landing-zone creation that automatically generates AlternateObjectTierLevelAttributes.Group filters from the ServiceEM naming convention and persists them to EntraOpsConfig.json. The implementation supports multiple runs with varying prefixes, merges without destroying existing filters, and an opt-in force overwrite for intentional replacement.
