4/4
published test cases matched
Current public validation artifact: 26 USC §1 2018 TCJA rate schedules matched expected outputs.
Validation
Trust should be inspectable.
This page only states what the repo currently supports in public artifacts. It is not a placeholder dashboard pretending the proof already exists.
100%
accuracy on that artifact
The published report records full agreement across the tested filing-status schedules.
$0.01
comparison precision
The validation methodology compares outputs to cent-level tolerance rather than using hand-wavy qualitative checks.
109k
cross-references mapped
The statute-graph analysis reports roughly 109,000 cross-references across 6,680 Internal Revenue Code subsections.
Methodology
What the current public proof covers
Direct extraction of formula logic from the encoding under test.
Representative test cases chosen across filing statuses and bracket ranges.
Manual expected-value calculations checked to cent-level tolerance.
Public artifacts that say exactly what has been validated and what has not.
Next milestone
What still needs to become public
Expand beyond the currently published 26 USC §1 rate-schedule artifact.
Expose machine-readable validation outputs instead of narrative-only reports.
Backfill public comparisons across more sections, years, and jurisdictions.
