Family Four: Self-verifying vector and GPU retrieval substrate: Same data, same result, verifiable at every step: every index proves it was built from the database it serves.

Same data, same result, verifiable at every step: every index proves it was built from the database it serves.. Methods and Systems for a Self-Verifying Deterministic Vector Index and GPU Retrieval Substrate Materialized From a Relational System of Record. U.S. Provisional Patent Application No. 64/148,001 (patent pending). Embodied in the vector store of the Inference Fabric. Traditional vector pipelines create multiple copies of data, a source database, a vector store, index files, GPU memory, with no provable link between them. Data can drift, go stale or be corrupted, and nobody can prove what produced a result. Here the relational database is the only authority. Vectors are exported deterministically into memory-mapped shards that serve reads and carry references back to the database; they are serving representations, never another authoritative copy.
