## Provenance and limits
Snapshot retrieved 2026-10-12T19:43:14.998Z. Source: https://as-dcc-pub-cann-w-p-002.azurewebsites.net/licenses/filteredSearch.
The snapshot contains 20937 distinct licence records and 15382 name entries. These are different populations: legal names and trading names can refer to the same licence.
A name match does not verify a product, ownership, authenticity or a supply-chain relationship. Status is as recorded at retrieval, not necessarily current.
No verified brand-to-factory graph, importer profiles, seller inventories, or price observations are currently published. Generated records have been removed. Empty results are a coverage gap, not evidence of illegality or absence.
