The "Obsidian" Security & Performance Update

[Harshit-J004]

This release marks the conclusion of our most rigorous security audit to date. We've synchronized the core security pipeline with our terminal dashboard and framework adapters to provide a 100% verified, deadlock-proof execution environment.

Here is what's new in v5.1.1:

Deep-Memory Injection Defense (Obsidian Grade)

We've neutralized a critical evasion vector in the prompt injection scanner.
• Binary-Path Scanning: The recursive DFS memory parser now natively decodes bytes and bytearray objects in both the core engine and the MCP Interceptor.
• 100% Detection Parity: Ensures that binary-encoded jailbreaks can no longer bypass obsidian-layer filters.

Dashboard & Telemetry Evolution

The Obsidian HUD has been upgraded for mission-critical reliability:
• High-Performance Telemetry: Replaced stub logging with a non-blocking File-Watcher pipeline. Interceptor events now stream in real-time without impacting agent latency.
• Dynamic Versioning: The dashboard now dynamically scales and versions itself directly from the core package metadata.
• Visual Asset Sync: Fully synchronized high-resolution Obsidian assets and optimized README documentation for PyPI/GitHub.

Framework Async Deadlock Resolution

During rigorous stress-testing of LangChain and CrewAI, we uncovered and patched two severe logic bugs in our orchestration proxies:
• Async Priority Fix: Corrected a bug where synchronous shadowing was causing asynchronous .coroutine and ._arun paths to be skipped.
• Extraction Parity: Both LangChain and CrewAI adapters are now mechanically verified to prioritize non-blocking async execution paths natively.

Security & Mathematical Bounding

• Public Webhook Privacy: Switched on strip_traceback=True support to prevent Python source code leakage in public-facing webhooks (Slack, Discord, Datadog). UI Patch: Slack and Discord alerts now natively render the traceback (or secure "STRIPPED" notice).
• Report Overflow Fix: Resolved a mathematical bug where coverage metrics could structurally exceed 100% during aggressive fuzzing runs.

ToolGuard v5.1.1 is recommended for all users running high-concurrency orchestrators and the MCP ecosystem.

Update now: $ pip install -U py-toolguard
