+- 설정에서 `on/off` 또는 숫자 입력이 필요한 신규 항목은 **기존 양식에 맞춰 통일해서 추가**해야 함
+- `on/off` 항목은 예외 없이 `ToggleSwitch` 스타일을 사용하고, 기본 CheckBox/임의 토글 버튼으로 새로 만들지 않음
+- 숫자 입력 항목은 가능하면 **텍스트박스 직접 입력 대신 기존 슬라이더 + 현재값 배지 패턴**을 우선 사용하며, 범위가 명확한 값은 반드시 이 패턴을 기본으로 채택
+- 숫자 설정을 부득이하게 텍스트 입력으로 받을 경우에도, 먼저 기존 설정창/AX Agent 내부 설정에 같은 유형의 컨트롤이 있는지 확인하고 그 양식을 재사용해야 함
+- 동일 성격의 설정은 메인 설정과 AX Agent 내부 설정에서 **표현 방식이 서로 다르면 안 되며**, 기존에 쓰던 컨트롤러/레이아웃 기준으로 맞춰 추가
 
 ### AX Agent 표현 수준 (필수)
 - AX Agent UI 표현 수준은 설정에서 반드시 3단계로 제공: **`풍부하게` / `적절하게` / `간단하게`**

   - Cowork/Chat 하단의 프리셋 안내 카드가 실제 결과를 가리던 문제를 수정했습니다. 이제 대화에 사용자/assistant 메시지가 생기거나 실행 중일 때는 해당 카드가 자동으로 숨겨집니다.
   - [ChatWindow.FooterPresentation.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.FooterPresentation.cs)에 남아 있던 깨진 한글 워터마크/안내 문구를 정상 한국어로 정리했습니다.
   - 라이브 타이핑 속도를 조정해 SSE 및 Cowork/Code 최종 프리뷰가 한 번에 붙는 느낌을 줄이고, 더 눈에 보이게 점진적으로 출력되도록 보정했습니다.
+- 업데이트: 2026-04-08 10:12 (KST)
+  - 등록 모델에 `동작 프로파일`을 추가했습니다. 이제 모델별로 `균형 / 도구 호출 우선 / 추론 우선 / 읽기 속도 우선 / 문서 생성 우선` 성향을 저장할 수 있고, 편집/추가 모두 내부 설정과 일반 설정에서 같은 값으로 유지됩니다.
+  - Cowork/Code 루프는 현재 활성 모델의 프로파일을 읽어 no-tool 감지 임계값, 도구 미호출 재시도, 문서 생성 재시도, terminal evidence gate, 읽기 도구 병렬 배치 수를 다르게 적용합니다.
+  - AX Agent 내부 설정의 Temperature 항목에 `자동 / 사용자 지정` 전환을 추가했습니다. 자동일 때는 등록 모델 프로파일의 temperature 정책을 따르고, 사용자 지정일 때만 슬라이더 값이 실제 tool 호출 온도로 적용됩니다.
+- 업데이트: 2026-04-08 10:38 (KST)
+  - 모델 실행 프로파일을 Cowork/Code 후속 게이트까지 더 깊게 연결했습니다. 이제 프로파일별로 post-tool verification, 코드 품질 게이트, 문서 검증 게이트, diff/실행 증거 게이트, final report 게이트의 강도를 다르게 적용합니다.
+  - `document_heavy` 프로파일은 `document_plan` 이후 장기 재시도보다 fallback 산출물 생성 쪽으로 더 빨리 전환되도록 조정했습니다.
+  - OpenAI/vLLM tool calling 바디에 `parallel_tool_calls` 힌트를 추가해 읽기 도구 병렬 실행 성향이 모델 요청 바디에도 반영되도록 보강했습니다.
+  - Cowork/Code 진행 표시에는 `계획 / 도구 / 검증 / 압축 / 폴백 / 재시도` 같은 단계 메타를 더 직접적으로 붙여, 오래 걸릴 때도 현재 단계가 더 잘 읽히게 했습니다.
+  - [docs/AX_AGENT_REGRESSION_PROMPTS.md](/E:/AX%20Copilot%20-%20Codex/docs/AX_AGENT_REGRESSION_PROMPTS.md)를 전면 정리해 `tool_call_strict`, `fast_readonly`, `document_heavy`, `reasoning_first` 프로파일별 회귀 시나리오를 고정했습니다.

 `claw-code`와 AX Agent를 같은 기준으로 비교하기 위한 공통 회귀 프롬프트 세트입니다.
 
 ## 사용 규칙
 
-- 런타임 동작, transcript 렌더, 권한/계획/질문 UX, queue/compact/reopen 흐름에 영향을 주는 변경 뒤에는 이 문서를 기준으로 최소 1회 점검합니다.
-- 모든 항목을 매번 수동 실행할 필요는 없지만, 관련 축이 바뀌었으면 해당 묶음은 반드시 확인합니다.
-- 결과는 “문장이 똑같은가”가 아니라 “실행 경로와 사용자 체감 결과가 같은가”를 봅니다.
+- 루프 정책, transcript 렌더, 권한/계획/진행 UX, queue/compact/reopen 흐름에 영향을 주는 변경 뒤에는 이 문서를 기준으로 최소 1회 점검합니다.
+- 모든 항목을 매번 전부 돌릴 필요는 없지만, 바뀐 영역과 맞닿은 묶음은 반드시 확인합니다.
+- 결과는 “모양이 똑같은가”보다 “사용자 체감 흐름과 완료 품질이 같은가”를 기준으로 봅니다.

 - Document update: 2026-04-07 09:19 (KST) - Restored the AX Agent footer/status total token aggregate so it no longer disappears after runs return to idle. The status strip now rehydrates totals from the current conversation message token sums when live loop counters are empty.
 - Document update: 2026-04-07 09:19 (KST) - Corrected context-compaction popup accuracy by switching its detail copy to the last real compaction metrics (`before -> after`, automatic/manual kind, cumulative compaction count, cumulative saved tokens) instead of only the generic trigger-threshold text.
 - Document update: 2026-04-07 09:19 (KST) - Prevented `total_stats` loop events from being swallowed into the generic process-feed path. AX Agent now routes those events back through the dedicated total-stats presentation so transcript summaries and footer token totals stay aligned.

+- [AppSettings.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Models/AppSettings.cs)
+  - `RegisteredModel.ExecutionProfile`과 `LlmSettings.UseAutomaticProfileTemperature`를 추가했다.
+  - 등록 모델은 실행 성향을 저장하고, AX Agent 내부 설정은 프로파일 기반 temperature 자동 적용 여부를 따로 제어한다.
+- [ModelExecutionProfileCatalog.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/ModelExecutionProfileCatalog.cs)
+  - `balanced`, `tool_call_strict`, `reasoning_first`, `fast_readonly`, `document_heavy` 실행 프로파일 카탈로그를 추가했다.
+  - 프로파일별로 초기 도구 강제, no-tool 임계값, 문서 재시도, 병렬 읽기 배치 수, terminal evidence gate, tool temperature cap을 함께 관리한다.
+- [SettingsViewModel.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/ViewModels/SettingsViewModel.cs)
+  - 등록 모델 로드/저장 시 실행 프로파일을 함께 유지하고, 모델 행에도 프로파일 레이블을 보관하도록 확장했다.
+- [ModelRegistrationDialog.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ModelRegistrationDialog.cs)
+  - 등록 모델 추가/편집 다이얼로그에 `실행 프로파일` 선택 UI를 추가했다.
+- [SettingsWindow.xaml.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/SettingsWindow.xaml.cs)
+  - 일반 설정의 등록 모델 추가/편집 흐름에서 실행 프로파일 값을 저장/수정하도록 연결했다.
+- [ChatWindow.xaml.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.xaml.cs)
+  - AX Agent 내부 설정의 등록 모델 추가/편집 흐름도 실행 프로파일을 저장하도록 맞췄다.
+  - 내부 설정 Temperature row에 `자동 / 사용자 지정` 선택을 추가하고, 자동일 때는 슬라이더를 읽기 전용처럼 비활성화해 프로파일 기반 정책이 우선되도록 했다.
+- [LlmService.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/LlmService.cs)
+  - 현재 활성 모델의 실행 프로파일을 조회하는 헬퍼와 프로파일 기반 tool temperature 계산을 추가했다.
+  - `UseAutomaticProfileTemperature=false`면 기존 사용자가 지정한 temperature를 그대로 사용한다.
+- [LlmService.ToolUse.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/LlmService.ToolUse.cs)
+  - tool calling 경로의 temperature를 일반 값 대신 프로파일 기반 `ResolveToolTemperature()`로 통일했다.
+- [AgentLoopTransitions.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/AgentLoopTransitions.cs)
+  - 읽기 도구 병렬 배치 계획에 `maxParallelBatch` 상한을 추가해 프로파일별 최대 동시 읽기 수를 제어할 수 있게 했다.
+- [AgentLoopTransitions.Execution.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/AgentLoopTransitions.Execution.cs)
+  - terminal evidence gate 재시도 횟수를 외부에서 주입받도록 바꿔 프로파일 기반 제어를 가능하게 했다.
+- [AgentLoopService.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/AgentLoopService.cs)
+  - Cowork/Code 루프 시작 시 현재 모델의 실행 프로파일을 읽어 no-tool 감지, 도구 미호출 재시도, 문서 생성 재시도, terminal evidence gate, 읽기 병렬 실행, 초기 compaction/memory pressure 정책을 함께 적용하도록 변경했다.
+  - `tool_call_strict`/`fast_readonly` 같은 프로파일은 초기 memory guidance와 aggressive compaction을 더 늦게 적용해, vLLM 계열에서 불필요한 프롬프트 팽창을 줄이는 방향으로 조정했다.
+

+
+- [ModelExecutionProfileCatalog.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/ModelExecutionProfileCatalog.cs)
+  - 실행 프로파일 정책을 확장해 `post-tool verification`, `코드 품질 게이트`, `문서 검증 게이트`, `diff/실행 증거 게이트`, `final report gate`의 강도까지 함께 관리하도록 바꿨다.
+  - `fast_readonly`와 `document_heavy`는 속도/산출물 우선으로 검증 게이트를 더 공격적으로 줄이고, `reasoning_first`와 `balanced`는 기존 품질 게이트를 유지하도록 정리했다.
+- [AgentLoopTransitions.Execution.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/AgentLoopTransitions.Execution.cs)
+  - 코드 품질 게이트, high-impact build/test 게이트, final report 게이트, diff/실행 성공 게이트, 문서 검증 게이트를 모두 프로파일 기반 재시도 횟수로 바꿨다.
+  - 문서 검증 관련 깨진 문자열을 정상 한국어로 복구하고, document verification gate가 실제 최대 재시도 수를 기준으로 동작하도록 수정했다.
+  - terminal document completion/post-tool verification 경로도 `EnablePostToolVerification` 정책을 읽어 profile별로 verification을 생략할 수 있게 했다.
+- [AgentLoopService.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/Agent/AgentLoopService.cs)
+  - `document_heavy`/`tool_call_strict` 프로파일에서는 `document_plan` 이후 장기 재시도보다 fallback 생성으로 더 빨리 전환되도록 조정했다.
+  - 후속 게이트 호출 시 현재 실행 프로파일을 함께 넘겨, Cowork/Code loop가 모델 성향에 맞는 검증 강도를 실제로 적용하도록 연결했다.
+- [LlmService.ToolUse.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Services/LlmService.ToolUse.cs)
+  - OpenAI/vLLM tool-use request body에 `parallel_tool_calls` 힌트를 추가해 읽기 도구 병렬 실행 성향이 모델 요청 단계에도 반영되도록 보강했다.
+- [ChatWindow.AgentEventRendering.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.AgentEventRendering.cs)
+  - Cowork/Code 진행 카드에 `계획 / 도구 / 검증 / 압축 / 폴백 / 재시도` 단계 메타를 더 직접적으로 붙여, 오래 걸리는 작업도 어느 단계인지 읽기 쉽게 정리했다.
+- [AX_AGENT_REGRESSION_PROMPTS.md](/E:/AX%20Copilot%20-%20Codex/docs/AX_AGENT_REGRESSION_PROMPTS.md)
+  - 회귀 프롬프트 문서를 전면 교체하고, `tool_call_strict`, `fast_readonly`, `document_heavy`, `reasoning_first` 프로파일별 검증 시나리오를 추가했다.
