Notes

D045 — assumptions held in a DB are tracked HERE under data sources, in addition to the assumption_domains.yaml registry. Owner = InsModel; read-only to consumers. CONCERN = assumption lifecycle/history (consolidated 2026-06-03, 16→10 tables; sole owner of base_standards). Still holds live sec_financial_data + market_data — those move to metrics.db (DS-073) / canonical-market-data.db (DS-077) in the tracked provider-switch.
