OrlogOpen source · Python · AI memory · MCP
Memory for AI agents that checks recalled claims against recorded evidence and abstains when it cannot verify them. Combines an append-only event log, point-in-time retrieval and an MCP server so developers can trace what an agent knew and why.
Roslyn analyzers that enforce architecture boundaries and AI context budgets during .NET builds. Includes mutation checks and an agent harness to detect boundary violations and keep architectural rules effective.
