RESO StandardStatus lookups + HistoryTransactional resource — the schema that models the historical layer

Summary

Claim. RESO models the listing-status layer with StandardStatus lookups (Active, Backup, Canceled, Closed, Expired, Pending, Withdrawn) and the HistoryTransactional resource (23 fields). These together model expired/terminated/suspended/cancelled/conditional ("Pending Sold" = firm, unconditional) statuses and relisting chains.

Confidence. Verified for the schema (StandardStatus + HistoryTransactional); industry-consensus for the analytic interpretations (relisting chains etc.).

Caveats. Local MLS implementations can extend or restrict the StandardStatus enumeration; do not assume the lookup is universal across boards.

Implication / use. The schema-side anchor for the cancel-and-relist tactic (Cancel-and-relist resets DOM to zero — Pasalis-adjacent practitioner (Globe & Mail); condo relistings hit 163pct of sales in mid-October in the 416; GTA condo months-of-inventory 3.1 in September) and any "relisting chain" analytics claim.
