Problem

Autonomous analysis workflow fails at final step when attempting to serialize CodeQLWorkflowResult to JSON. The to_dict() method uses asdict() which doesn't convert pathlib.Path objects to strings, causing TypeError: Object of type PosixPath is not JSON serializable.

Current incorrect fix: Adding default=str at json.dump() site treats symptom, not cause.

Root Cause

The to_dict() method in CodeQLWorkflowResult (agent.py:46-59) manually converts languages_detected but relies on asdict() for everything else. Python's asdict() doesn't convert non-dataclass types like Path.

Affected Path Objects (4 total)

databases_created[lang].database_path (Optional[Path])
analyses_completed[lang].database_path (Path)
analyses_completed[lang].sarif_path (Optional[Path])
sarif_files (List[Path]) - Type annotation incorrectly claims List[str]

Impact

autonomous_summary.json cannot be created
Autonomous analysis workflow incomplete
All analysis succeeds but final report fails

Fix

Extend to_dict() in CodeQLWorkflowResult to manually convert all Path objects to strings.

File: packages/codeql/agent.py:46-59
