+# VeriLoop
+
+**VeriLoop** is a model and runtime initiative built around **E³-Loop**, an evidence-driven closed-loop reasoning architecture created and designed by **Libo Wang**.
+
+Our core belief is simple: the future of advanced language models should not be locked behind ever-rising fine-tuning cost, closed infrastructure, or fragile model-specific customization.  
+VeriLoop explores a different path—one where open-weight models can be upgraded into an **agentic runtime system** through **context engineering as the primary control surface**, reinforced only by **minimal, targeted PEFT** where necessary.
+
+## What makes VeriLoop different
+
+Most model stacks still treat the base model as the final product.  
+VeriLoop treats the base model as a **replaceable cognitive substrate**.
+
+At the center of the VeriLoop family is **E³-Loop**: a runtime control architecture designed around:
+
+- **budget-bounded truth-seeking convergence**
+- **evidence–conclusion alignment**
+- **execution-trigger discipline**
+- **revision fidelity under contradiction**
+- **near-zero tolerance for high-risk fabrication**
+
+Instead of relying on repeated large-scale parameter fine-tuning for every new model generation, VeriLoop is designed to shift the center of gravity toward:
+
+- **structured state control**
+- **evidence-aware routing**
+- **external verification loops**
+- **rollback and revision governance**
+- **persistent runtime contracts**
+- **context-engineered agentic behavior**
+
+This is not just a different optimization strategy.  
+It is a different answer to what a “foundation model” should be.
+
+## The E³-Loop view
+
+E³-Loop is not a simple wrapper around an LLM.  
+It is a control plane that organizes reasoning, evidence, action, verification, revision, and termination into one auditable loop.
+
+In the VeriLoop view, a model should not merely generate plausible text.  
+It should be able to:
+
+1. form a working hypothesis,
+2. decide whether outside evidence is required,
+3. retrieve or execute when needed,
+4. detect contradiction,
+5. revise minimally rather than regenerate blindly,
+6. stop when truth-seeking progress no longer justifies additional budget.
+
+That shift—from best-effort generation to **budget-aware convergence toward truth**—defines the direction of the VeriLoop family.
+
+## Open-weight compatible by design
+
+VeriLoop is designed to work **with** open-weight ecosystems, not against them.
+
+We believe the real long-term value is not tied to one frozen checkpoint, but to a **portable runtime architecture** that can evolve across model generations.  
+As new open-weight backbones appear, the E³-Loop framework is intended to make them compatible with the VeriLoop paradigm through runtime adaptation, context engineering, and minimal targeted alignment layers.
+
+This means model progress should no longer be reset every time a new backbone appears.  
+The goal is continuity of capability without throwing away prior engineering investment.
+
+## Why this matters
+
+The dominant path in large-model development has pushed the field toward escalating cost, repeated retraining, and brittle post-hoc adaptation.
+
+VeriLoop was created from a different first principle:
+
+> advanced reasoning systems should become **more reusable, more auditable, and more economically survivable** as the ecosystem evolves.
+
+We are especially interested in a future where powerful open-weight models can be transformed into evidence-driven, agentic runtime systems without requiring each user or organization to repeat the full cost of model-specific reconstruction.
+
+## Our direction
+
+VeriLoop aims to help redefine the meaning of a base model:
+
+- from a static parameter artifact  
+- to a **runtime-upgradable reasoning substrate**
+
+- from isolated prompting  
+- to **stateful evidence-governed control**
+
+- from one-off tuning cycles  
+- to **portable, architecture-level capability transfer**
+
+- from model version dependency  
+- to **open-weight continuity**
+
+## API-first vision
+
+VeriLoop is being built with an **API-first service vision**.
+
+Our long-term direction is to make the VeriLoop effect available as a technical service layer that can connect to compatible open-weight backbones and elevate them into the VeriLoop family of evidence-driven runtime systems.
+
+We believe the next wave of model value will not come only from owning bigger checkpoints.  
+It will come from building the right control architecture on top of open intelligence.
+
+## Founder and architecture origin
+
+**Libo Wang** is the creator and architectural designer of the **E³-Loop** framework that defines the VeriLoop series.
+
+VeriLoop exists to explore a new paradigm for language models—one that is:
+
+- more rigorous than prompt-only systems,
+- more reusable than backbone-specific fine-tuning,
+- more auditable than opaque agent stacks,
+- and more economically realistic for the open model era.
+
+## Status
+
+VeriLoop is an evolving research and engineering initiative.  
+Current work focuses on the control-plane foundations required for evidence-driven model runtime, including schema contracts, state governance, memory/evidence interfaces, sandbox-linked verification, context engineering, and minimal PEFT for targeted stabilization.
