tcvn-compliance-copilot

Retrieval over the corpus of Vietnamese building standards — QCVN 06 fire safety, QCVN 10 accessibility, TCVN 2737 loads and others — pointed at a drawing set, producing findings a reviewer can act on rather than a chat transcript. Where tcvn-rules-engine answers questions that can be written as a rule, this one handles the far larger space that cannot: the clauses that are prose, the requirements that depend on reading a drawing, the checks a human would do with the standard open on the desk.
