[GRADE B -- royal.uk Court Circular (Neo4j Engagement nodes)]
The local Neo4j graph contains an Engagement dataset imported from royal.uk Court Circular pages (970 entries, 1997-2025). Filtering for royal_member containing "Duke of York" returns 2 entries in 2009, 3 in 2010, 18 in 2011, and 17 in 2012.
Notably, the imported dataset contains no Duke of York Court Circular entries in these windows that overlap key Windsor-axis emails in this dossier:
This is a public schedule context check only. Court Circular coverage is not comprehensive (and the import is not a complete mirror), so absence of an entry is not proof of no engagement or no travel.
WHAT THIS SHOWS AND DOES NOT SHOW: This graph-derived schedule layer suggests the key July 2009 / Aug 2010 / Feb 2011 Windsor-axis emails align with periods where no Duke of York Court Circular engagement entries appear in the imported dataset. It does NOT prove a private meeting occurred, and absence of an engagement entry does NOT establish that Andrew was not engaged elsewhere.
