Sites seed inventory from the Asset Collector script or spreadsheet exports, but lookup names drift between sources (Dell vs Dell Inc.), which would otherwise create duplicate vendors/models/types on every import. The importer now normalizes and fuzzy-matches near-miss references onto existing lookup rows within an operator-set similarity threshold, auto-applying the match while reporting it for review so nothing merges silently. Operating systems and asset rows are never reconciled. Adds the dedicated Import Site Assets page with script/template download and a multi-file dry-run/commit workflow.
