How many properties were added and updated over a timeframe, straight from the live MLS sync into Supabase (listings). Use the quick ranges or pick a custom window. New = created_at; updated = updated_at (CT).
Same two clocks as above, on pure_open_house_events. Added = promoted_at (when PURE ingested it); updated = source_modified_at (when NTREIS last touched it).
The agent and brokerage rosters behind every listing. New = first seen by PURE; updated = any touch on the row.
