We start where the data is richest, where the regulatory environment is the most navigable, and where our team has direct reach. The US is not the prize — it is the proving ground. Every system, every rubric, every safety policy must work at one-country scale before we replicate it. The temptation to launch globally on day one is the failure mode of every Muslim institution. We resist it.
- OpenStreetMap US extract (1,223 mosques) + Ihsan Standard auditor (1,393 mosques with EIN + transparency claims)
- HFSAA certified-entity directory (25 halal restaurants/butchers with full address + cert evidence)
- Postgres + PostGIS schema with claim ledger; 420 cross-source duplicates auto-merged
- UmmahPassport SSO with PKCE — confidential-client, pairwise sub, HMAC session
- Privacy-first stack: MapLibre + OpenFreeMap + Esri satellite + self-hosted Photon (planned); coordinate snap to ~110m before any network call
- Public rubric v0.1 — four pillars per entity type, partner-authored, semver-versioned
- Dedup precision ≥97%Cluster-and-merge pass on 150m radius matches by name similarity. We measured 420 / 2,641 records de-duplicated cleanly; sampled audit confirms <3% false-merges. The Valley Ranch case (OSM node + OSM polygon + Ihsan Standard) resolves to one canonical row.
- Privacy contract upheldUser coordinates never leave the device unsnapped. Server logs strip to 2 decimals (~1.1 km). Geocoder runs server-side so the user's IP never reaches Nominatim. Quarterly audit by an external HR org.
- Defamation safetyHard rule: no negative glow on the map. Self-claim shortfalls are routed to the relevant cert body, not publicly red-marked. Cleared by counsel before any score goes live.
- Methodology partner LOIsAt least one signed LOI per scoring pillar before that pillar is enabled. Today: outreach to Bahu Trust (env), Lilly Ihsan Standard at IU (transparency), IFANCA + HFSAA + HMC (halal cert), ISPU (civic), Open My Mosque + Hind Makki (women's space), Janazah Project (funerals).
- Audit coverage≥250 mosques carrying at least one third-party-audited claim from a signed partner. ≥50 with full transparency-pillar coverage.
- Cert-body coverage≥500 halal restaurants with at least one active cert (HFSAA / IFANCA / HMC). ≥3 cert bodies actively syndicating their certified list.
- Owner claim flow≥100 mosques claimed by their leadership via UmmahPassport SSO. Edit audit log running cleanly. Takedown SLA <72 hours.
- Contributor trust≥1,000 UmmahPassport-verified contributors, weighted by historical claim accuracy. Paid editorial team in place for cold-start moderation.
