## Description

WeChatMsg is a database forensic parser and local data processor designed to extract and reconstruct structured message data from raw binary files. By operating entirely on the host machine, the tool ensures data sovereignty and privacy, performing all decryption and transformation tasks without requiring network access or external dependencies.

The project distinguishes itself through a static analysis-based extraction method that reconstructs message threads by matching unique identifiers and timestamps across fragmented database tables. Its decoupled architecture separates low-level binary reading from high-level data formatting, utilizing a schema-driven engine to translate proprietary records into human-readable formats. This approach allows for consistent data migration and preservation across different software versions.

Beyond its core utility, the repository includes a comprehensive governance framework and engineering standards. These documents establish operational principles and technical guidelines to maintain codebase quality and facilitate collaborative stewardship among contributors.
