Summary

  • Fixed _analyze_error, _generate_fix, _validate_fix, and _finalize node
    functions in AutoDebugAgent to return new partial state dicts instead of
    mutating the input state in-place
  • Updated return type annotations from AutoDebugState to dict[str, Any]
  • Added TDD BDD tests verifying no in-place mutation occurs

Problem

The node functions in AutoDebugAgent violated the LangGraph node contract by
mutating the input state dict in-place and returning the full state object.
This is inconsistent with context_analysis.py and plan_generation.py.

Fix

Each node function now returns only the keys that changed:

  • _analyze_error: returns {"messages": [*existing, new_message]}
  • _generate_fix: returns {"current_fix": fix_data}
  • _validate_fix: returns {"fix_validated": is_valid} (plus "attempted_fixes")
  • _finalize: returns {"result": {...}}

Testing

  • Added 5 BDD scenarios verifying non-mutating behavior
  • All existing AutoDebugAgent tests continue to pass
  • Quality gates: lint ✓, typecheck ✓, unit_tests ✓

Closes #10496

Node functions _analyze_error, _generate_fix, _validate_fix, and _finalize
previously mutated the input state dict in-place and returned the full state
object, violating the LangGraph node contract which requires returning only
a dict of state updates (changed keys).

This fix updates all four node functions to return new partial state dicts
containing only the changed keys, consistent with the correct pattern already
used in context_analysis.py and plan_generation.py.

Changes:
- _analyze_error: returns {"messages": [*existing, new_message]}
- _generate_fix: returns {"current_fix": fix_data}
- _validate_fix: returns {"fix_validated": is_valid} plus "attempted_fixes" when invalid
- _finalize: returns {"result": {...}}
- All four functions now have return type dict[str, Any] instead of AutoDebugState
- Added TDD BDD tests verifying no in-place mutation occurs
