v0.4.0

Professional Audit & SSD Optimization

The v0.4.0 release introduces two critical features for enterprise and forensic environments: Professional Audit Logging and Hardware-Level SSD TRIM support. This system provides verifiable proof of data destruction and enhances reliability on modern storage media.

Tip

Audit & SSD Performance
Use the new --audit-log flag to generate a forensic report, and the --trim flag to ensure that SSD controllers are informed of block deallocation—a key step for anti-forensics on Flash media.

Key Enhancements

• Forensic Reporting System: A new reporting engine that tracks every file targeted, recording success/failure, precise timestamps, and the specific destruction methods applied.
• SSD TRIM/Discard Support: Implemented platform-specific hardware commands (fallocate on Linux, DeviceIoControl on Windows) to inform SSDs of discarded blocks, bypassing hardware-level remapping artifacts.
• Multi-Format Export: Support for human-readable Text reports and machine-readable JSON exports for integration into security dashboards.

Technical Implementation

• Structured Serialization: Integrated serde and serde_json for robust data representation and export.
• Atomic Aggregation: Implemented a thread-safe event bus to summarize session metrics (total files, successes, failures) without bottlenecking the parallel destruction logic.
• Extended CLI Schema: Added --audit-log <PATH> and --audit-format <text|json> to allow precise control over forensic output.
