Pulls CMDB server and client CIs from ServiceNow and writes a denormalized device-to-business-app-and-environment mapping to Excel. Joins via cmdb_rel_ci with an assigned-user ownership fallback for clients that have no direct app relationship.
Implements the nine queries from the AD pre-population spec as a single read-only PowerShell script: master server inventory, computer + service account + gMSA SPNs, sites, subnets, OU distribution, stale servers, domain controllers, and a coverage summary. Adds a derived workload classification CSV that joins all SPN sources against the service-class reference table so SQL/IIS/Exchange/etc. workloads can be picked up without scanning the servers. https://claude.ai/code/session_01Mv4u6bByTyy75mWPzod2Y4

Summary
Combines two independent DMC pre-population extractors onto a single branch so they can ship as a unified suite:
ad-pre-population-extractor/— PowerShell extractor pulling server inventory, SPN-derived workload signals, sites/subnets, OU distribution, stale-server detection, and a coverage summary from Active Directory (originates from PR Add AD pre-population extractor for Dr Migrate #17 / branchclaude/ad-pre-population-extractor-JQmg2).servicenow-cmdb-export/— Python CLI exporting CMDB CIs (server-app mapping) from ServiceNow (originates from branchclaude/export-server-app-mapping-Q2gRB).The two tools share a CSV-per-source output convention but otherwise stay independent — no integration code is added in this branch. Merge was conflict-free (paths don't overlap).
