VB-OS Documentation
Deterministic execution authority for systems operating under execution risk. Binary ASSERT/DEFER verdicts. Replayable. Model-independent.
VB-OS (Verification-Boundary Operating System) is execution authority infrastructure — a deterministic layer that independently authorizes operational decisions before consequential actions execute. Learn what VB-OS is and how it works.
What do you want to do?
Section titled “What do you want to do?”Build With It
Integrate VB-OS into your application using the Python SDK, Node.js SDK, CLI, or REST API.
Understand It
Learn how evidence, boundaries, evaluations, and replay work together to produce deterministic governance verdicts.
What VB-OS Does
Section titled “What VB-OS Does”VB-OS answers one question at execution time: should this action proceed?
The answer is always binary: ASSERT (execution authorized) or DEFER (execution withheld). Every verdict is deterministic, reproducible, and replayable from immutable artifacts.
Verify Workloads
Submit evidence to a boundary and receive a deterministic verdict. Every evaluation is reproducible.
Replay Decisions
Reproduce any historical evaluation from frozen artifacts. Same inputs, same boundary version, same evaluator, same verdict.
Connect Evidence Sources
Integrate external systems as evidence providers with provenance tracking.
Certify Compliance
Run multi-evaluation certification models with auditor-ready evidence chains.
