+## Handoff Context — Agent Ontology → Agent Artifact
+
+**Scope:** Party, Person, Company, Party Role, Contact Address, Address
+
+**Key decisions:**
+- Party uses bitemporal tracking — both valid-time and transaction-time
+  required. AUSTRAC audit trail obligation drives this, not a modelling
+  preference. Do not collapse to append-only.
+- Company is a concrete specialisation of Party, not abstract. Enables direct
+  instantiation without requiring a subtype record.
+- self_referential relationship on Party carries relationship_attributes as
+  edge properties (Association Type, Verified). Generate a bridge table for
+  the many-to-many, not a FK on Party.
+
+**Rejected alternatives:**
+- Separate PartyAssociation entity — creates unnecessary indirection for
+  graph traversal and was explicitly rejected by the domain owner.
+- Append-only mutability for Party — rejected because AUSTRAC requires
+  point-in-time reconstruction, not just event log replay.
+
+**Do not re-open:**
+- Risk Rating and Sanctions Screen Status are enums, not FK lookups.
+- Next Review Date does not require a NOT NULL constraint — it is calculated
+  and will be null at creation.
+- The Financial Crime domain classification is Highly Confidential throughout.
+  No override discussion needed.
+
+**Task for next agent:**
+Generate dimensional DDL for Party, Person, Company, Party Role, Contact
+Address, and Address. Target: Snowflake. Apply SCD Type 2 for slowly_changing
+entities. Party Identifier is the natural primary key — no surrogate needed.
