johnxu22786/auditrail: DeepSeek Harness Security Audit and Session Forensics

`auditrail` is a Bundle plugin in the DeepSeek Harness (DSH) ecosystem that fills the gap in security auditing. By subscribing to DSH streams, it fully records tool call chains, sensitive operations, and session details, and uses SQLite WAL mode and hash chains for secure storage and tamper detection. The plugin supports sensitive operation marking, privacy masking, multi-dimensional query and export, and terminal session replay, providing a security baseline for compliance review and risk traceability in AI agent environments.
