# Project Brief lda.chat is a workflow substrate for AI-agent-facing workspace automation. The prototype separates external planning from deterministic workflow execution. Key achievements: - Typed Draft, Artifact, Deployment, Run, and Trace lifecycle records. - Source-provider boundary for platform, MCP, Python, and experimental OpenAPI sources. - JSON-RPC and CLI surfaces usable by external agents and human operators. - Deterministic report and browser-click examples with audited agent challenge runs. Current positioning: - The system is not a bundled autonomous planner. - External agents or humans operate the workflow lifecycle. - The next product-facing step is a local Workflow Console and defense demo.
