Every source is graded on a four-tier hierarchy, and conflicts resolve down it. Tier 0 is primary law — 183 gazettes, statutes, named regulations, court judgments and regulator notices. Tier 1 is multilateral, DFI and official statistics. Tier 2 is premium commercial intelligence. Tier 3 is news and law-firm advisory. Tier 0 beats Tier 1 beats Tier 2; same-tier disagreements are presented as a range.
bRRAIn retrieves only from the catalog, answers only from what it retrieves, and every citation is resolved against the catalog by code before it reaches you. A fabricated source cannot survive the guard. When no catalogued source covers a question, Atlas flags the gap rather than answering from memory. Regulatory claims are checked against each instrument's effective date and supersession status, so an answer never rests on a repealed rule.
The index scores each country 0–100 on a composite plus four cluster sub-scores (critical minerals, infrastructure, FDI, energy), banded Satisfactory / Partial / Weak / Failing. It is built from catalogued primary data — governance indices, sanctions and counterparty overlays, DFI exposure, and macro stability — each constituent source-linked. The methodology is public and versioned; underlying weights are proprietary.
Corrections are public and versioned. Any figure or answer later found to rest on a superseded or retracted source is logged on the errata page — credibility is demonstrated, not asserted.
