+The company artifact contains every normalized issuer version so temporal
+foreign keys from instruments can resolve. The screener snapshot freezes the
+production clock at the consistent Firestore
 watermark rather than using a different wall clock on every request. A baseline
 is generated by the existing `computeScreenerRow` and `hasDataQualityIssues`
 functions directly from all 737 current Firestore company rows. The Parquet
 build then joins those metrics to the schema-valid normalized company rows.

+The current-company subset still contains exactly the same 737 issuers consumed

 encoding, statistics and content-addressed filenames. Embedded metadata records
 schema version, source revision, source watermark and builder version.

+Status: complete and validated  
+Date: 17 July 2026  
+Odoo task: 3.5, `project.task` 584
+
+Documents, dated instrument positions/reference identities and events are split
+by their declared year partition, sorted by the v1 catalog order and written as
+content-addressed Zstandard Parquet with 8,192-row groups. The small year files
+allow DuckDB/Arrow readers to prune historical ranges while preserving stable
+ticker/date/ID pagination.
+
+The validator requires unique catalog primary keys and checks:
+
+- every document/event issuer exists in company history;
+- every instrument issuer has a company version at or before its as-of date;
+- every event document ID resolves;
+- every event instrument identity resolves, including null-quantity registry
+  reference rows; and
+- deliberately duplicated and orphaned mutations are rejected.
+
+Golden reconstruction covers the BHP company/instrument projection, the ATM
+annual report and the three-record A11 same-day pagination order.
