## Overview

Ghost Data Still Exists is a deterministic deletion-audit agent. It takes deletion requests and supplied identity, activity, policy, and evidence files; resolves identity and resource ownership; reconstructs state at each audit time; classifies intent and applies retention and remediation rules; then emits ordered findings, remediation, and verification steps to CSV. The README documents the stages and capabilities; the pipeline excerpt confirms orchestration calls. Reader-level wiring and the command-line entry point’s internals were not sampled, so those links rely on README statements.
