Changelog

0.1.0 — Initial release

Initial version of the independent loopgrid-langchain Python integration:

• Genuine LangChain 1.x AgentMiddleware covering synchronous and asynchronous tool execution.
• Decision-scoped model/context/authority correlation, SHA-256 proposal commitments, signed LoopGrid Core policy and review verification.
• Fail-closed conservative dispatch reservation, shared-leasing requirement, durable single-host SQLite lease helpers, and replay rejection.
• Exact tool argument snapshot and tool-object/name consistency checks.
• Native tool_result separated from trusted application tool_executed receipts and independently observed outcome_observed evidence.
• Explicit genuine model observation, privacy-preserving commitments, E2E scripts, security regression suite and cross-platform CI configuration.

See VALIDATION.md for dated test evidence and SECURITY.md for security boundaries. This version does not claim third-party marketplace validation, live model-provider execution or production operational certification.
