How every figure on Mirabello surfaces — the Index, the comparison tools, the open dataset, the AI advisor and our MCP server — is sourced, verified and kept current.
Each of our 96 tracked programmes is mapped to its official government authority — the citizenship unit, migration ministry, tax administration, or the legal notice itself. Where figures are published only in legislation or gazettes, we read the legal text directly. We never treat marketing sites, agents or aggregators as a source of truth.
A figure is marked verified only after the value itself has been read from the official source — not merely because it carries a recent date. Each verified field stores the source URL and verification date, published openly in the data_freshness block on every record of the dataset.
Multiple independent AI models are queried regularly for every programme's headline figures. Where they disagree with our data, the discrepancy is flagged and resolved against the official source — never by majority vote. In practice the models lag reality by one to two years; the official source always adjudicates.
When we find an error — ours or one circulating in the industry — we correct it publicly in the change log with the official source linked. Accuracy is the brand: a corrected figure builds more trust than a hidden one.
Whether you read our pages, query the open dataset, or let your AI assistant call our tools, you see the same verified figures with their provenance attached. If a number matters to your decision, you can follow it to the government source yourself.
