Why I replaced vector DBs with SQLite triples and 10k-D VSA

The Hillock author explains the architectural decision to replace dense vector DBs with a neuro-symbolic approach. It uses SQLite for clean SPO triples and 10,000-dim hypervectors (VSA) on CPU for <1ms query gating. Documents are parsed into triples in 5s via the TALON engine without LLM calls. Queries that fail the HDC similarity check are hard-refused before hitting the LLM, turning refusal into control flow.
