SAULSGPT — DATA SYNCHRONIZATION MANAGER

========================================

Guarantees 100% data symmetry between the GNN Knowledge Lattice

and the ChromaDB Vector Database.



When any new legal doctrine, case precedent, or statutory provision

is added to the GNN, this manager automatically:

1. Validates presence in ChromaDB.

2. Computes 384-dimensional dense semantic embeddings (all-MiniLM-L6-v2).

3. Upserts verbatim statutory text & legal definitions into ChromaDB.

4. Ensures zero orphaned nodes and zero unindexed text chunks.
