Trust Engine · live UAD 3.6 coverage

We publish our gaps.
Nobody else does.

Every appraisal-software vendor claims "UAD 3.6 ready." None of them tell you which spec UIDs they actually emit, which they registered but don't ship, or how the count was computed. This page does — generated from the same coverage telemetry our CI runs on every commit. If a number on this page is off, our tests fail.

Last regenerated: __GENERATED__

Required spec UIDs
100%(115 of 115)

UIDs Fannie / Freddie REQUIRE on every URAR 1004.

Conditionally-required UIDs
32%(242 of 749)

UIDs required on specific assignment types (condo, ADU, manufactured, cost approach, etc.).

Section bindings shipping XML
99%(69 of 70)

Spec-binding sections wired into the generator. The rest are in active development.

Coverage measurement updated 2026-05-05. Previous count included 4 fields that ship in MISMO XML but weren't bound through our spec system. Count now reflects bindings only.

By section, every UAD 3.6 field we cover

For every URAR section, here's the count of UAD 3.6 spec UIDs we map and how many ship XML today. "Active development" means we have the binding written but the generator emit path isn't wired yet — these are tracked publicly so you can see exactly what's in flight.

What's in active development

These spec-binding sections have UIDs registered but the XML emitter isn't wired yet. Tracked here so you know what's coming — and what's blocking which assignment types.

sales_comparison

Compare to Aivre, Total/Cotality, SFREP, ClickFORMS, ACI: none of them publish a list like this. Their "UAD 3.6 ready" badge tells you nothing about which assignment types ship clean today. We tell you.
