Section 02
Traditional UI automation testing faces severe scalability challenges. Every time a test fails, the team has to invest a lot of effort in root cause analysis. Common failure types include:
Many existing AI testing solutions often operate like a "black box", automatically patching code without providing transparency into the decision-making process. This lack of interpretability not only reduces team trust but also adds complexity to long-term maintenance.
Section 03
This intelligent agent called the "Autonomous Test Repair System" aims to reduce test maintenance costs through automatic diagnosis and repair. It simulates senior QA engineers' capabilities and executes a complete four-stage pipeline:
Section 04
The system captures high-fidelity evidence during test execution, including detailed logs, DOM tree structures, and screenshots. This comprehensive evidence collection provides a solid foundation for subsequent diagnosis.
Section 05
The system uses a hybrid diagnostic strategy. For common failures (such as timeouts, network errors), deterministic heuristics are used for immediate identification; for complex logical issues, large language models are called for in-depth analysis.
Section 06
The system synthesizes all evidence to develop a repair plan and records the entire reasoning process in a structured JSON artifact. This documented reasoning process ensures full transparency of decisions.
Section 07
The system applies the repair solution and generates a detailed Execution Timeline to prove the effectiveness of the changes.
Section 08
Every repair includes a HealingDecision JSON artifact that allows you to accurately trace why a specific change was made. This transparency is a core advantage that traditional "black box" AI tools do not have.

Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
This project explores how to use Large Language Models (LLMs) to detect logical vulnerabilities in Ethereum smart contracts, especially business logic flaws that are difficult for traditional static analysis tools to capture, such as economic manipulation and execution order errors.
This article introduces an open-source project for building modern large language models from scratch. The project evolves from a GPT-2-style basic architecture to a Llama 2/3-style production-level implementation, covering complete tutorial implementations of key technologies such as RMSNorm, RoPE, SwiGLU, GQA, and MoE.
