Added

• Packaged the BAML source and generated client under src/lerim/agents/ so future agents can share the same BAML/LangGraph layout.
• Added the production BAML/LangGraph extract package with deterministic trace windowing, typed BAML scans, record synthesis, context-store persistence, and structured graph events.

Changed

• Replaced sync extraction with the BAML/LangGraph harness while keeping maintain, ask, and working-memory on PydanticAI.
• Updated extraction evals, integration tests, docs, and run artifacts to use graph events instead of PydanticAI extract messages.
• Tuned extraction prompts to avoid storing incidental personal names unless identity itself is the durable context.

Fixed

• Hardened session catalog/API status paths so catalog storage issues degrade status responses instead of crashing status or maintain.
• Made extraction persistence idempotent when a rebuilt session catalog replays a session whose episode already exists.
• Improved long-running extraction queue handling so transient SQLite heartbeat write failures and sequential processing do not create false stale-running jobs.

Removed

• Removed the legacy PydanticAI extract agent, extract-only trace tools, history processors, and the experimental baml_agents/ sidecar.
