Counting and privacy. Projects group only where the exact canonical planning authority and full planning reference match. Known official wrappers around the same full CN/SN reference are one event; different dated commencement events remain separate. Highest unconflicted event units and floor area are shown, never summed. Personal names, contact details, Eircodes and raw private addresses remain outside this public projection.
