Methodology
How NaVi works
Every rule you see went through the same pipeline: researched from primary sources, independently cross-checked, and dated so you know exactly how current it is.

The pipeline
Four steps, every corridor, no exceptions
Step 1
Research per corridor, from primary sources
For every country we cover, research starts at the source - government portals, tax authorities, treaty texts, official guidance. Not blog posts, not forum answers. Each rule is written down with the exact source, its publication date and the quote it rests on.
Step 2
An independent adversarial cross-check
A second, independent pass then tries to break every rule we wrote. It goes back to the live web with no memory of the first pass's conclusions and checks each rule against its sources on its own terms - agree, disagree or unverifiable.
Step 3
Disagreements get fixed and documented
Anything short of a clean agreement stays flagged and lands in the admin review queue with a note on exactly what was contested. Nothing ships as verified until a human resolves it - agreement clears the flag, disagreement fixes or removes the rule.
Step 4
Freshness, dated and enforced
Every rule carries the date it was last checked. Corridors that move fast get re-checked more often than quiet ones. If a rule changes after your report ran, your report tells you so instead of quietly going stale.
The honest part
What this is, and what it is not
Information, not advice
NaVi tells you what applies and how sure we are. It does not replace a lawyer, accountant or immigration adviser for a binding decision - it tells you when to bring one in.
Confidence levels, not false certainty
Every finding carries a confidence score. When we do not have enough of your facts, or a rule is still provisional, the report says so plainly instead of rounding up to certain.
The review queue is real, and it is working
34 rules are sitting in it right now, held back from full verification until a human closes the disagreement. That is the system catching itself, not a gap we are hiding.
