 - **IDP CLI `chat` Command & SDK `ChatOperation`** — Interactive Agent Companion Chat from the terminal and programmatic SDK access. Runs the same multi-agent orchestrator as the Web UI locally, with real-time streaming and multi-turn conversation support. Includes Analytics Agent, Error Analyzer Agent, and optionally Code Intelligence Agent (`--enable-code-intelligence`). Available as `idp-cli chat --stack-name <stack>` for interactive use, `--prompt` flag for single-shot scripting, and `client.chat.send_message()` in the Python SDK. See `docs/idp-cli.md#chat`.
 
-- **Per-Class Extraction Model Override** — New `x-aws-idp-extraction-model` JSON Schema extension allows overriding the global `extraction.model` on a per-document-class basis. Useful when certain document types benefit from a different model (e.g., a more powerful model for complex financial forms, a faster/cheaper model for simple documents). Classes without the extension continue to use the global default. Works with both traditional and agentic extraction modes. See `docs/extraction.md` — Per-Class Extraction Model Override section.
