1. Executor V2 Prompt

• 1.1 Update src/main/resources/prompts/chat-executor-prompt.md so the final contract uses answer_version="executor_evidence_v2".
• 1.2 Remove diagnosis_summary and user_facing_answer from the required Executor output schema and validation rules.
• 1.3 Keep claims, hypotheses, recommended actions, missing information, and evidence-binding rules.
• 1.4 Keep Planner and tool-use behavior unchanged.

2. Runtime Rendering Safety

• 2.1 Update ChatService PASS handling so V2 structured output is rendered into readable Chinese instead of raw JSON.
• 2.2 Preserve V1 user_facing_answer extraction for compatibility.
• 2.3 Ensure fallback behavior does not expose raw Executor JSON when structured rendering fails.

3. Parser Compatibility

• 3.1 Keep VerifierInputHook parse-only behavior compatible with V2 output.
• 3.2 Add or update tests proving V2 output without user_facing_answer parses into executor_structured_output.

4. Tests And Verification

• 4.1 Add or update ChatService tests for PASS with executor_evidence_v2.
• 4.2 Add or update tests proving final user answer does not contain raw JSON contract text.
• 4.3 Run targeted tests for ChatService and VerifierInputHook.
• 4.4 Validate this OpenSpec change.
