Decision Systems Engineer — VFS Protocol
I design and validate decisions under uncertainty.
The VFS Method — Validation & Forensic Standards — is a structured protocol for producing defensible decisions in high-stakes environments. It eliminates opinion as the primary input. It replaces intuition with evidence. It documents everything.

Unvetoed Failures
01
Decisions must be defensible
Every decision this system touches must be reproducible, traceable, and withstand external challenge. Defensibility is not optional—it is the minimum standard.
02
Evidence over opinion
Assertions without structured evidence are noise. The system accepts data, documentation, and verifiable inference. Nothing else qualifies.
03
The veto protects the system
When evidence is incomplete, contradictory, or unverifiable, the correct output is not a decision—it is a stop. The veto is a feature, not a failure.
04
Structure precedes scale
A decision made without a framework cannot be validated at volume. Governance must be established before velocity is introduced.
05
Chain of custody is non-negotiable
Who held the decision, when, and under what authority must be recorded. A decision without provenance is not a decision—it is a guess.
Validation &
Forensic Standards
VFS treats every decision as a live document. It passes through a 5-field intake, a structured validation process, and an evidence-grading standard derived from Daubert precedent. The output is not a recommendation — it is a decision packet that can be challenged, audited, and defended.
