Long-form practitioner guides organized by jurisdiction. Each section is backed by primary authority (statute, regulation, agency publication, or case). When no primary authority can be confirmed for a point, the section renders the verbatim “Unable to confirm as of [date]” note instead of guessing.

Seven verticals: US state & local tax (SALT), US employment compliance, US federal government contracts (FAR / DFARS), cross-border privacy & data protection, international trade & tariffs, global mobility / cross-border employment, and state entity registration & compliance. Newer verticals are still being drafted — guides without sections are clearly marked.

As of 2026-07-24, BifröstIndex has 721 published guides comprising 7,835 sections across 69 jurisdictions and seven verticals: 155 US state & local tax (SALT), 312 US employment compliance, 8 US government contracts (FAR/DFARS), 82 privacy & data protection, 72 international trade & tariffs, 73 global mobility / cross-border employment, and 19 entity registration & state compliance.
