How Veridue builds
rules you can trust
Every rule in Veridue is source-linked, time-stamped, versioned, and assigned a confidence rating. If we can't cite it, we don't present it as a deterministic rule.
Our "Rule Capsule" Standard
Every compliance obligation in Veridue must satisfy this schema:
Authority
Who says this? (e.g., IRS, Texas Comptroller)
Jurisdiction
Where does it apply? (e.g., US Federal, California)
Obligation
What must be done? (e.g., File Form 941)
Due Logic
Human-readable + machine-computable logic.
Source URL
Direct link to primary source (PDF/webpage).
Retrieved Date
When we last verified the source.
Confidence
High / Medium / Low rating based on source quality.
Confidence Ratings
Primary authority clearly states the deadline logic (e.g., official agency guidance, statute, official deadline calendar).
Authority implies logic but leaves ambiguity (e.g., multiple filing frequencies; "varies by taxpayer" without a clear classifier).
Secondary summaries, blog posts, or unclear documents. We avoid using these unless there is no primary source available.
Updates & Change Control
Continuous MonitoringSource checks are scheduled and also triggered by detected authority changes.
Versioned RulesEach rule change increments a version and logs "what changed / why".
Preserved ProofProof packs serve as a snapshot, linking back to the specific rule version used at the time of filing.
How do you handle holidays?
We only apply "next business day" logic when the authority explicitly supports it. Where rules are county-administered (e.g., BPP), we treat the county as the authority to avoid statewide over-generalization.
