LoopGrid LangChain v0.1.0

LoopGrid LangChain v0.1.0 — Initial Release

Native LangChain 1.x AgentMiddleware integration for signed, tamper-evident decision evidence and guarded tool execution.

Highlights

• Synchronous and asynchronous native LangChain tool middleware
• Decision, policy and signed human-review evidence through LoopGrid Core
• Exact tool-call argument commitments and conservative replay protection
• Separate tool-result, execution-receipt and observed-outcome evidence
• Shared dispatch-lease interfaces and privacy-conscious evidence recording

Validation

• 114 unit and security tests passed
• 94.81% statement coverage
• Native LangChain and local LoopGrid Core end-to-end tests passed on Windows
• Wheel and source distributions validated
• Fresh-wheel consumer installation passed

Compatibility: Python 3.10+ and LangChain 1.x (>=1.2,<2).

This release provides the LangChain adapter, not a hosted LoopGrid Core service. See README.md and SECURITY.md for integration requirements and security boundaries.
