Collection Workflow

We combine automated discovery with human review. Every rule stores its source URL, access date, and a content hash for change detection.

1. Discover

Use Tavily search to locate official visa requirement pages.

2. Extract

Parse visa requirement tables and normalize to a typed rule.

3. Verify

Cross-check 10% sample with Timatic and flag conflicts.

4. Refresh

Weekly spot checks, monthly full refresh, advisory-triggered updates.
