Primary Sources
- Federal Register, IRS IRB, Treasury, TN DOR. — Primary-source input for the pending product methodology
Entity-Graph Join
document ID, topic taxonomy, state code, affected NAICS/entity class.
Publication Rule
Branmoor does not treat raw public records as the product. A surface is publishable only when the source record is dated, normalized, source-linked, and joined to the relevant Branmoor entity identifiers with enough confidence to state the limits of the result.
Current Methodology Note
Pending methodology. Source contract: Federal Register, IRS IRB, Treasury, TN DOR. Records will be normalized into the Branmoor entity graph. Join path: document ID, topic taxonomy, state code, affected NAICS/entity class. The public preview will publish only after Branmoor can state source cadence, lineage, and coverage limits.
Limits
Coverage follows the underlying source. Missing state portals, gated APIs, PDF-only filings, suppressed fields, lagged agency refreshes, and entity-name ambiguity can all limit product completeness. Pending products are not marketed as live until those limits are documented on the product surface.
