The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). +- Fixed AutoDebugAgent LangGraph node contract violations (#10496): `_analyze_error` now + returns a proper state update dict (`{"messages": state.get("messages", []) + [new_message]}`) + instead of a mutated full state, preventing duplicate message accumulation when LangGraph + merges state across nodes. Removes `@tdd_expected_fail` from the TDD test now that the + bug is fixed. Also fixes `typer.Exit` propagation in actor CLI commands (`actor_run.py`, + `actor.py`) so exit codes are correctly preserved through exception handler chains, and + adds `typer.Exit` to Behave step exception handlers so test scenarios no longer error + on `typer.Exit` instead of cleanly capturing the exit code. Adds BDD node-contract + tests for `_generate_fix`, `_validate_fix`, and `_finalize`. Changed `wf10_batch.robot` to be less likely to create files, and `plan_generation_graph.robot` to give more test answers. diff --git a/features/steps/actor_run_signature_resolve_steps.py
