# Verified Answers (VQR)

> How the Assistant reuses human-verified question-and-SQL pairs to answer data questions reliably.

When a user marks an Ask answer as **verified**, Platinur stores the question and its approved SQL in the Verified Question Repository (VQR) for that environment.

## How reuse works

* **Exact match.** If a later question is an exact match to a verified one (case- and whitespace-insensitive), the assistant re-runs the approved SQL directly and returns a fresh answer marked verified — the model is not invoked.
* **Near match.** If the question is similar but not identical, the verified question-to-SQL pairs are injected into the model's context as grounding. The model reuses the approved SQL rather than re-deriving it.

## Environment scope

Verified answers are scoped to the environment in which they were verified. A Staging-verified answer is never reused to answer a question in Prod, and vice versa. The governed-marts guard enforces this boundary and fails closed.

## Setup

No new configuration is required. Marking an answer as verified in the Ask interface is the only action needed. There is no new API endpoint.
