-# FESA Reference Cases
-
-Use this skill to inventory the minimum stored reference inputs and CSV quantities that a
-feature actually compares. Abaqus is an external numerical reference, not the FESA formulation
-or behavior specification.
-
-## Inputs
-
-Read these first:
-
-- `AGENTS.md`
-- `docs/SOLVER_AGENT_DESIGN.md`
-- `docs/reference-models/README.md`
-- `docs/requirements/<feature-id>.md`
-- `docs/formulations/<feature-id>-formulation.md`
-- `docs/numerical-reviews/<feature-id>-review.md`
-- `docs/io-definitions/<feature-id>-io.md`
-- Existing files under `reference/`
-
-## Workflow
-
-1. Read the feature requirements and list only blocking and warning-only reference quantities.
-2. Inventory each existing case using its exact directory, input filename, and required CSV filenames.
-3. Confirm the input and every required comparison CSV are present and readable.
-4. Record the FESA HDF5 dataset, source identity column, required component columns, and stable matching rule.
-5. Require unique source IDs, complete required row sets, and finite comparison values.
-6. Copy the approved tolerance and blocking/warning behavior without inventing or calibrating values.
-7. Map each reference-comparison requirement to at least one existing case when the feature requires that coverage.
-
-Do not require or create:
-
-- canonical directories or filenames;
-- legacy-alias approvals;
-- bundle `README.md` or `metadata.json`;
-- Abaqus version or generation provenance;
-- duplicated units, coordinates, step/frame, material, section, thickness, or element-type metadata;
-- a reference CSV schema version;
-- CSV files for quantities outside the approved comparison boundary;
-- an expanded benchmark portfolio unless the feature requirements explicitly require it.
-
-Read source element type, material, section, loads, constraints, and supported single-step
-identity from the `.inp`. Do not rename, repair, normalize, or generate reference artifacts.
-
-## Output Contract
-
-Produce or revise `docs/reference-models/<feature-id>-reference-models.md` with:
-
-- Metadata
-- Reference Acceptance Scope
-- Reference Case Inventory
-- HDF5-to-CSV Comparison Mapping
-- Tolerance and Blocking/Warning Policy
-- Readiness Checklist
-- Open Issues and Downstream Handoff
-
-## Boundaries
-
-- Do not implement code or parsers.
-- Do not design C++ APIs or file ownership.
-- Do not run Abaqus, Nastran, or another reference solver.
-- Do not generate or modify reference inputs or CSV files.
-- Do not compare solver results.
-- Do not approve release readiness.
-
-## Quality Gate
-
-- Every blocking or warning-only quantity names an exact input/CSV pair.
-- Every comparison defines an HDF5 projection, source-ID/component mapping, and tolerance.
-- Missing, extra, duplicate, and nonfinite required rows have an explicit fail-before-tolerance rule.
-- Use `needs-reference-artifacts` only when a declared input or required comparison CSV is missing.
-- Use `needs-user-decision` only when required quantities, matching, or tolerance are undefined.
-- Canonical naming, README, metadata, provenance, and unrequested portfolio coverage never block readiness.

-physical expectations to Physics Evaluation Agent.

-## 목적
-이 문서는 Abaqus, Nastran과 같은 유한요소법 기반 구조해석 솔버를 개발하기 위한 AI Agent 운영 구성을 정의한다.
+## 목적과 범위
 
-이번 구성안은 ALL-FEM 논문의 구조를 확장하거나 재사용하는 계획이 아니다. 논문은 Agent 설계를 위한 참고 자료로만 사용하며, 본 프로젝트는 C++/MSVC 기반 독립 솔버 개발 워크플로우를 따른다.
+이 문서는 FESA 기능 개발을 조정하는 agent 계층, 8단계 workflow, gate와 산출물 계약을
+정의한다. `coordinator-agent`가 유일한 main agent이며, 나머지 10개 profile은 Coordinator가
+호출하는 sub-agent다. 모든 기능별 agent 산출물은 `docs/<feature-id>/`에 모은다.
 
-## 설계 원칙
-- 기능 요구조건, 이론 정식화, 코드 구현, 검증, 배포 역할을 분리한다.
-- 실행 가능성만으로 성공을 판단하지 않고, 레퍼런스 결과와 물리량을 비교해 기능 완료를 판정한다.
-- 테스트는 구현 전에 준비한다. 개발 대상 솔버 테스트와 레퍼런스 솔버 결과 비교 테스트를 함께 사용한다.
-- Abaqus나 Nastran을 Agent가 직접 실행하지 않는다. 기능이 선언한 기존 `.inp`와 실제
-  비교에 필요한 Abaqus CSV만 read-only 검증 기준으로 사용한다. Canonical naming,
-  README, metadata, version 또는 provenance는 기본 readiness 조건이 아니다.
-- FESA는 Abaqus와 독립적인 solver다. Agent는 Abaqus 내부 formulation, integration,
-  stabilization 또는 recovery equivalence를 요구하거나 추론하지 않는다.
-- 기본 개발 환경은 C++17 이상, MSVC, CMake, CTest이다.
-- 모든 기능은 tolerance 기준을 명시하고, 기준을 만족할 때만 배포 후보가 된다.
-- Harness 운영은 `docs/HARNESS_WORKFLOW.md`의 계획, 독립 Step 실행, PreToolUse/Stop 검증 계층을 따른다.
+이 workflow는 개발 운영 계약이다. Solver C++ 아키텍처, CMake/CTest target, Harness
+executor와 hook, Abaqus reference artifact 또는 승인된 FEM 기능 의미를 바꾸지 않는다.
 
-## Harness Step 실행 계약
+## Agent 계층
 
-계획과 구현 Agent는 작업 전 `docs/HARNESS.md`와 `docs/HARNESS_WORKFLOW.md`를 읽는다.
-Implementation Planning Agent는 multi-Step 초안을 사용자에게 승인받은 뒤 planning files만
-materialize하며 Step을 선택하거나 실행하지 않는다. Executor는 별도의 명시적 사용자 요청으로
-`scripts/execute.py`를 실행할 때 branch, pending Step 선택, retry, timestamps, commits, Step
-advancement와 phase status를 소유한다.
+### Coordinator Agent: main-agent orchestration
 
-Implementation Agent는 approved plan, materialized phase files, Executor-selected current
-`stepN.md`만 사용해 `RED -> observed failure -> minimal GREEN -> focused/full VERIFY`를 완료하고
-다음 Step을 시작하지 않는다. Agent가 쓸 수 있는 Harness metadata는 current Step의 `status`와
-`summary`, `error_message`, `blocked_reason` payload뿐이다. `.codex/hooks.json`이 PreToolUse
-interception과 Stop whole-project validation을 자동 실행하므로 hook entry point를 수동 실행해
-대체하지 않는다. 세부 schema와 recovery 절차는 `docs/HARNESS_WORKFLOW.md`를 따른다.
+Coordinator Agent는 기능 요청을 접수하고 다음 실행 loop를 소유한다.

-- 결과 비교를 위해 FESA HDF5 dataset과 Abaqus reference CSV row의 ID/컴포넌트 규약을 맞춘다.
-
-주요 산출물:
-- 입력 데이터 schema

-이름, README, metadata, provenance 또는 비교하지 않는 quantity CSV를 요구하지 않는다.
+승인된 Abaqus `.inp` subset, semantic model mapping, validation diagnostic, authoritative
+`results.h5` schema와 reference CSV row schema를 `io.md`에 정의한다. Numerical/reference
+gate가 확정한 logical quantity와 source identity를 최종 HDF5 dataset projection 및 CSV
+column mapping으로 연결하는 책임은 이 agent에 있다.

-## 검증 Gate
+Compile, link, ordinary test와 명확한 implementation-owned mismatch는 Implementation Agent가
+먼저 수정한다. 반복되거나 불명확한 실패만 Correction loop로 보낸다. Upstream contract
+gap은 Coordinator가 해당 owner 단계로 되돌린다.
 
-### Gate 1: 요구조건 승인
-통과 조건:
-- 대상 기능과 제외 범위가 명확하다.
-- 입력, 출력, tolerance, 검증 물리량이 정의되어 있다.
-- 레퍼런스 비교 방식이 정해져 있다.
+## Gate 계약
 
-### Gate 2: 정식화 승인
-통과 조건:
-- 요소 정식화와 수치적분 규칙이 문서화되어 있다.
-- 좌표계, 자유도, 부호 규약이 명확하다.
-- Numerical Review Agent가 주요 수치 위험을 검토했다.
+1. Requirements gate: `requirements.md`가 범위, acceptance criteria, 검증량과 tolerance를
+   고정한다.
+2. Research gate: `research.md`가 필요한 이론, benchmark와 applicability evidence를 제공한다.
+3. Formulation gate: `formulation.md`가 구현 가능한 수치 계약을 제공한다.
+4. Numerical/reference merged gate: `numerical-review.md`와 `reference-model.md`가 함께 통과한다.
+5. I/O gate: `io.md`가 source identity와 logical quantity를 authoritative `results.h5` dataset,
+   units, coordinates, component와 CSV column에 최종 투영한다.
+6. Implementation gate: 승인 계획, RED/GREEN/VERIFY evidence, full MSVC x64 Debug build/CTest,
+   deterministic row precheck와 blocking/warning reference comparison이 모두 통과한다.
+7. Physics gate: `physics-evaluation.md`가 `pass-for-release-agent`다.
+8. Release gate: `release.md`가 `ready-for-release`이고 Coordinator가 closure를 기록한다.
 
-### Gate 3: 테스트 준비 승인
-통과 조건:
-- 구현 전 실패해야 하는 테스트가 정의되어 있다.
-- 기능이 요구하는 기존 input/CSV pair와 blocking/warning quantity가 명확하다.
-- 필요한 source ID/component matching과 tolerance가 정의되어 있다.
+Reference comparison은 source identity와 component로 행을 결정적으로 대응시키며 missing,
+extra, duplicate 또는 nonfinite required row를 tolerance 전에 거부한다. CSV는 외부 reference이고
+FESA의 authoritative output은 `results.h5`다.
 
-### Gate 4: 구현 검증
-통과 조건:
-- CMake/MSVC/CTest validation이 통과한다.
-- 단위 테스트와 통합 테스트가 통과한다.
-- 관련 C++ test file이 있고 같은 구현 Step 안에 RED 실패와 후속 GREEN 성공 증거가 있다.

+## 요구사항 단위 산출물 구조
 
-### Gate 5: 레퍼런스 검증
-통과 조건:
-- 기능이 blocking으로 선언한 Abaqus CSV quantity와 구현 solver HDF5 quantity가
-  tolerance 안에 있다.
-- Warning-only quantity는 결과와 경고가 리포트에 남고 pass/fail을 바꾸지 않는다.
-- Required source row/component의 누락, 추가, 중복 또는 nonfinite 값이 없다.

-
-권장 비교 방식:
-- authoritative 비교는 FESA `results.h5` rows와 Abaqus reference CSV rows 기준으로 수행한다.
-- FESA HDF5에서 추출한 deterministic CSV view는 debugging/review 보조 artifact로만 사용한다.
-- scalar 값: absolute tolerance와 relative tolerance를 함께 적용한다.
-- vector 값: component-wise 비교와 norm 비교를 함께 기록한다.
-- stress tensor: component-wise 비교를 기본으로 하고, 필요한 경우 principal stress 또는 von Mises stress를 추가 비교한다.
-- 반력: 전체 하중 평형과 개별 구속 자유도 반력을 모두 확인한다.
-
-권장 리포트 항목:
-- model name
-- compared quantity
-- number of compared rows
-- maximum absolute error
-- maximum relative error
-- RMS error
-- worst node or element id
-- pass/fail
-
-## 반복 실패 처리
-
-반복 실패가 발생하면 Correction Agent가 무한 수정 루프를 계속하지 않는다. 다음 중 하나로 분류해 Coordinator Agent에 보고한다.
-
-- 요구조건 불명확
-- 정식화 오류 가능성
-- reference artifact 오류 가능성
-- I/O schema 불일치
-- 구현 결함
-- tolerance 기준 부적절
-- 테스트 모델이 기능을 과도하게 또는 불충분하게 검증함
-
-Coordinator Agent는 분류 결과에 따라 Requirement, Formulation, I/O Definition, Reference Model, Implementation Agent 중 적절한 단계로 되돌린다.
-
-## 초기 적용 우선순위
-
-1. 선형 정적 해석의 최소 골격
-2. Isoparametric 3D Euler beam element
-3. 1D truss 또는 bar element
-4. 2D plane stress/plane strain element
-5. 3D solid element
-6. material model 확장
-7. nonlinear 또는 dynamic analysis 확장
-
-각 단계는 요구조건, 정식화, 테스트모델, 구현, 레퍼런스 비교, 배포 Gate를 독립적으로 통과해야 한다.
-
-## 운영 메모
-
-- Agent 산출물은 가능한 한 문서, 테스트, 비교 리포트 형태로 남긴다.
-- 사람이 제공한 Abaqus reference artifact는 현재 path/name 그대로 read-only로 사용한다.
-  별도 provenance, README 또는 metadata가 없다는 이유로 gate를 차단하지 않는다.
-- reference artifact가 바뀌면 기능 구현 변경과 같은 수준으로 검토한다.
-- 기능 구현 완료 판정은 build/test와 기능별 blocking reference validation 통과를 기준으로
-  한다. Physics evaluation과 release readiness는 별도 후속 배포 gate다.
+산출물이 필요하지 않았거나 기존 workflow에 없었던 경우 placeholder를 만들지 않는다.
+`corrections.md`는 실제 on-demand correction이 발생했을 때만 생성한다. Reference input/CSV는
+현재 path와 name 그대로 read-only로 사용하고, 문서 정리를 위해 rename 또는 보정하지 않는다.

 ## 목적
 
-이 문서는 FESA 유한요소 기반 구조해석 솔버 개발에 사용할 project-local Codex skill 구성을 정의한다.
+이 문서는 FESA의 8단계 feature workflow에서 사용하는 project-local skill 구성을 정의한다.
+Agent는 역할과 책임 단위이고 skill은 여러 agent가 재사용하는 절차, 품질 gate와 handoff
+단위다. 모든 feature별 skill output은 `docs/<feature-id>/`에 기록한다.
 
-Agent는 역할과 책임 단위이고, skill은 여러 Agent가 반복적으로 사용하는 절차와 검증 도구 단위다. 따라서 skill은 Agent와 1:1로 대응하지 않는다. 대신 요구조건, 연구, 정식화, I/O 계약, reference model, C++ TDD 구현, reference 비교, 물리 검토, release readiness처럼 솔버 개발 과정에서 반복되는 작업 흐름을 기준으로 구성한다.
+실제 실행 지침의 source of truth는 각 `.codex/skills/<skill-name>/SKILL.md`다. 이 문서는
+skill inventory와 책임 분리를 사람이 읽을 수 있게 설명한다.
 
 ## 설계 원칙
 
-- Skill은 `.codex/skills/<skill-name>/SKILL.md`에 둔다.
-- 각 skill은 필수 frontmatter `name`, `description`과 UI metadata `agents/openai.yaml`을 가진다.
-- Skill 본문은 agent TOML의 역할 설명을 반복하지 않고, 입력, 절차, 산출물, 금지사항, 품질 gate, handoff를 정의한다.
-- Skill은 `AGENTS.md`와 `docs/SOLVER_AGENT_DESIGN.md`를 공통 상위 기준으로 읽는다.
-- Abaqus, Nastran 또는 reference solver 실행은 skill 범위에 포함하지 않는다.
-- Abaqus reference CSV 파일 생성/수정은 skill 범위에 포함하지 않는다.
-- C++ 구현 관련 skill은 C++17 이상, MSVC, CMake, CTest, TDD 원칙을 따른다.
-- C++ 검증 명령은 `.harness/config.json` 또는 `docs/HARNESS.md`의 자동 감지 기본값을 따른다.
-- Harness Python 변경은 `uv run --with pytest python -m pytest -v -rs`로 검증한다.
+- 각 skill은 `SKILL.md`의 `name`, `description` frontmatter와 `agents/openai.yaml` UI metadata를
+  가진다.
+- Skill은 입력, workflow, output contract, boundaries, quality gate와 handoff를 정의한다.
+- 공통 상위 계약은 `AGENTS.md`와 `docs/SOLVER_AGENT_DESIGN.md`다.
+- Abaqus, Nastran 또는 다른 reference solver 실행과 reference CSV 생성/수정은 skill 범위가
+  아니다.
+- C++ 절차는 C++17 이상, MSVC x64 Debug, CMake/CTest와 TDD를 따른다.
+- 검증 명령은 `.harness/config.json`을 우선하고 없으면 `docs/HARNESS.md`의 자동 감지
+  기본값을 따른다.
+- Skill output path에는 agent별 폴더를 만들지 않고 `docs/<feature-id>/`만 사용한다.

-# Correction Report 문서 작성 가이드
-
-이 디렉터리는 Correction Agent가 작성하거나 제안하는 기능별 correction report를 보관하는 위치다.
-
-Correction Agent는 Build/Test Executor Agent, Reference Verification Agent, Physics Evaluation Agent가 전달한 실패를 triage하고, implementation-owned failure만 최소 수정으로 복구한다. 이 agent는 source, header, test, CMake 수정은 수행할 수 있지만 requirements, formulations, I/O contracts, reference artifacts, tolerance policies는 수정하지 않는다.
-
-기본 문서명은 `docs/corrections/<feature-id>-correction.md` 형식을 사용한다.
-
-## Correction Agent 역할
-
-수행한다:
-- 실패 로그와 implementation report를 읽고 failure classification을 먼저 확정한다.
-- configure, compile, link, test, reference-comparison, harness, environment, upstream-contract 실패를 구분한다.
-- implementation-owned failure에 한해 source/header/test/CMake를 최소 수정한다.
-- 수정 후 targeted command를 먼저 실행하고 `.harness/config.json` 또는 자동 감지 기본값에 따른 전체 MSVC build/test를 실행한다.
-- Harness Python, Hook, agent config 관련 수정에서는 `uv run --with pytest python -m pytest -v -rs`도 실행한다.
-- 반복 실패 또는 upstream 계약 문제를 Coordinator Agent나 관련 upstream agent로 handoff한다.
-
-수행하지 않는다:
-- requirements를 수정하지 않는다.
-- formulations를 수정하지 않는다.
-- I/O contracts를 수정하지 않는다.
-- numerical review reports를 수정하지 않는다.
-- reference artifacts를 수정하지 않는다.
-- tolerance policies를 수정하지 않는다.
-- Abaqus, Nastran 또는 reference solver를 실행하지 않는다.
-- Abaqus reference CSV 파일을 생성하거나 수정하지 않는다.
-- release readiness, reference tolerance success, physics validation success를 승인하지 않는다.
-- 최종 reference verification report 또는 physics validation report를 작성하지 않는다.
-
-## 실행 순서
-
-Correction Agent는 항상 다음 순서를 따른다.
-
-```text
-TRIAGE -> MINIMAL FIX -> VERIFY -> REPORT
-```
-
-기본 검증 명령은 다음과 같다.
-
-```powershell
-<targeted command that reproduced the failure>
-cmake -S . -B .harness/build -A x64
-cmake --build .harness/build --config Debug
-ctest --test-dir .harness/build -C Debug --show-only=json-v1
-ctest --test-dir .harness/build -C Debug --output-on-failure
-```
-
-Preset 또는 직접 MSBuild 프로젝트는 `.harness/config.json`의 설정을 따른다. Harness
-Python, Hook, agent config, Python validation behavior가 correction 범위에 포함될 때는
-`uv run --with pytest python -m pytest -v -rs`도 실행한다. Stop 검증은 응답 종료 전에
-같은 전체 프로젝트 검증을 다시 수행한다.
-
-## Failure Classification
-
-- `configure`: CMake configure, preset, generator, cache setup 실패
-- `compile`: C++ compilation 실패
-- `link`: linker, symbol resolution, target dependency 실패
-- `test`: CTest, unit, integration, parser/I/O, ordinary regression test 실패
-- `reference-comparison`: 저장된 reference artifact와 deterministic comparison 실패
-- `harness`: Python Harness test, PreToolUse/Stop Hook, config loading, discovery, adapter validation 실패
-- `environment`: MSVC, CMake, Python, path, permission, generator, local dependency 문제
-- `upstream-contract`: requirements, formulation, I/O, reference artifact, tolerance, implementation plan 불일치 또는 누락

-## Risks and Downstream Handoff
-
-### Implementation Agent
-- <task order, tests to write first, candidate files, acceptance criteria>
-
-### Build/Test Executor Agent
-- <validation commands, expected CTest labels, feature-specific commands>
-
-### Correction Agent
-- <likely failure classifications and upstream rollback guidance>
-
-### Reference Verification Agent
-- <planned HDF5/CSV comparison tests, exact case paths, tolerance mapping, source-ID/component matching>
-
-## Harness Step Draft
-
-| step | name | owned layer/module | prerequisite files | RED/GREEN/VERIFY | acceptance commands | stop condition |
-| ---: | --- | --- | --- | --- | --- | --- |
-| 0 | <kebab-case> | <one scope> | <exact paths> | <test-first sequence> | <exact commands> | <condition> |
-
-User approval is required before materializing this draft under `phases/`.
-
-## Executor Handoff
-
-- Executor authorization: separate explicit user request for `scripts/execute.py`.
-- implementation input: approved plan, materialized phase indexes, and Executor-selected current
-  `stepN.md`.
-- implementation recipe: `RED -> observed failure -> minimal GREEN -> focused/full VERIFY`.
-- metadata ownership: Implementation Agent records only the current Step `status` plus `summary`,
-  `error_message`, or `blocked_reason`; Executor records branch, pending-Step selection, retry,
-  timestamps, commits, advancement, and phase status.
-- hooks: `.codex/hooks.json` automatically invokes PreToolUse and Stop; never manually run hook
-  entry points as substitutes.
-
-## Open Issues
-- <requirement, formulation, I/O, required comparison file/mapping, tolerance, or architecture issue>
-```
-
-## 품질 기준
-
-- 모든 `must` requirement는 최소 하나의 task와 test에 연결되어야 한다.
-- C++ production 변경마다 선행 테스트 파일 또는 테스트 추가 계획이 있어야 한다.
-- reference comparison이 필요한 기능은 exact existing input/required CSV path와 FESA
-  HDF5-to-reference-CSV source-ID/component mapping test 계획을 가져야 한다.
-- Implementation Planning Agent는 Harness Step 초안을 사용자에게 승인받은 뒤에만 phase
-  index와 step files를 생성하며 executor는 자동 실행하지 않는다.
-- CMake/CTest 계획은 MSVC x64 Debug 검증 경로와 호환되어야 한다.
-- 구현 계획은 테스트 작성, 실패 확인, 최소 구현, validation 순서를 명시해야 한다.
-- upstream 문서가 불완전하면 값을 임의로 채우지 않고 `needs-upstream-decision` 또는 `blocked`로 표시한다.
-- release 완료나 reference tolerance 통과 판정은 하지 않는다.

-# I/O 정의 문서 작성 가이드
-
-이 디렉터리는 I/O Definition Agent가 작성하거나 제안한 기능별 입출력 정의 문서를 보관하는 위치다.
-
-FESA 솔버의 입력 파일은 Abaqus input file이다. 다만 초기 FESA는 Abaqus 전체 문법 호환을 목표로 하지 않고, 기능별로 지원할 Abaqus keyword subset과 내부 모델 매핑을 명확히 정의한다.
-
-기본 파일명은 `docs/io-definitions/<feature-id>-io.md` 형식을 사용한다. 각 문서는 Requirement Agent, Formulation Agent, Numerical Review Agent의 산출물을 입력으로 받아 Abaqus `.inp` 입력 계약, authoritative HDF5 result schema, FESA HDF5 to Reference CSV comparison schema를 정의해야 한다.
-
-## I/O Definition Agent 역할
-
-I/O Definition Agent는 Abaqus input file subset, 내부 solver model mapping, output request mapping, HDF5 result schema, reference CSV comparison row schema를 정의한다.
-
-수행한다:
-- 기능별 supported Abaqus keyword subset을 정의한다.
-- unsupported, ignored-with-warning, requires-user-decision keyword 정책을 정의한다.
-- model data와 history data를 내부 solver 개념으로 매핑한다.
-- node, element, set, material, section, boundary condition, load, step, output request의 의미 계약을 정의한다.
-- `results.h5`의 authoritative HDF5 schema를 정의한다.
-- 기능이 선언한 existing Abaqus CSV와 비교하기 위한 최소 source-ID/component mapping을 정의한다.
-
-수행하지 않는다:
-- parser를 구현하지 않는다.
-- C++ API나 파일 구조를 설계하지 않는다.
-- Abaqus, Nastran 또는 레퍼런스 솔버를 직접 실행하지 않는다.
-- Abaqus reference CSV 파일을 생성하거나 수정하지 않는다.
-- solver 결과와 reference 결과를 비교하지 않는다.
-- release readiness를 승인하지 않는다.
-- 명시적으로 정의되지 않은 Abaqus full compatibility를 주장하지 않는다.

-# 수치 검토 리포트 작성 가이드
-
-이 디렉터리는 Numerical Review Agent가 작성하거나 제안한 기능별 수치 검토 리포트를 보관하는 위치다.
-
-기본 파일명은 `docs/numerical-reviews/<feature-id>-review.md` 형식을 사용한다. 각 리포트는 Formulation Agent의 정식화 문서를 독립 검토해, 구현 계획 단계로 넘겨도 되는지 판단한다.
-
-## Numerical Review Agent 역할
-
-Numerical Review Agent는 정식화의 수학적 일관성, 수치 안정성 위험, 검증 준비 상태를 검토한다.
-
-수행한다:
-- 수식의 차원, 부호, 좌표 변환, 적분 규칙을 검토한다.
-- `B` matrix 또는 kinematic operator, constitutive contract, element equation을 검토한다.
-- rigid body modes, patch test, symmetry, positive definiteness를 확인한다.
-- hourglass, shear locking, volumetric locking, distortion, singular Jacobian, conditioning 위험을 식별한다.
-- 구현 계획 전에 필요한 정식화 수정, 연구 보강, reference model 요구사항을 작성한다.
-
-수행하지 않는다:
-- C++ 코드를 구현하지 않는다.
-- 정식화 문서를 직접 수정하지 않는다.
-- C++ API나 파일 구조를 설계하지 않는다.
-- Abaqus, Nastran 또는 레퍼런스 솔버를 직접 실행하지 않는다.
-- Abaqus reference CSV 파일을 생성하거나 수정하지 않는다.
-- release readiness를 승인하지 않는다.
-- 레퍼런스 결과와 구현 솔버 결과의 일치 여부를 판정하지 않는다.

-# Physics Evaluation Report 문서 작성 가이드
-
-이 디렉터리는 Physics Evaluation Agent가 작성하거나 제안하는 기능별 physics evaluation report를 보관하는 위치다.
-
-Physics Evaluation Agent는 Reference Verification Agent가 `pass-for-physics-evaluation`로 넘긴 결과에 대해 물리적 타당성을 검토한다. 이 agent는 reference tolerance를 다시 판정하지 않고, FESA `results.h5`, Abaqus reference CSV files, optional FESA debug CSV view를 읽기 전용 evidence로 사용해 평형, 반력 부호, 변위 방향, 대칭성, 요소내력/응력 위치, rigid body mode 징후, energy/residual sanity, 테스트 모델 coverage를 검토한다.
-
-기본 문서명은 `docs/physics-evaluations/<feature-id>-physics-evaluation.md` 형식을 사용한다.
-
-## Physics Evaluation Agent 역할
-
-수행한다:
-- Reference Verification report가 `pass-for-physics-evaluation`인지 확인한다.
-- documented physical expectation이 있는 항목만 pass/fail로 판정한다.
-- global equilibrium, reaction consistency, displacement direction, symmetry, element force balance, stress/strain sanity, rigid body mode, energy/residual, model coverage를 검토한다.
-- 물리 검토 실패를 equilibrium-failure, reaction-inconsistency, displacement-direction-failure, symmetry-failure, stress-location-failure, element-force-inconsistency, rigid-body-mode-suspected, nonfinite-result, model-coverage-gap, upstream-contract, environment로 분류한다.
-- 실패 원인에 따라 Correction Agent, Reference Model Agent, Formulation Agent, I/O Definition Agent, Coordinator Agent로 handoff한다.
-- 모든 물리 검토가 문서화된 기대값을 만족하면 Release Agent로 handoff한다.
-
-수행하지 않는다:
-- source code를 수정하지 않는다.
-- tests를 수정하지 않는다.
-- CMake files를 수정하지 않는다.
-- requirements, formulations, I/O contracts, reference model contracts를 수정하지 않는다.
-- reference artifacts 또는 tolerance policies를 수정하지 않는다.
-- Abaqus, Nastran 또는 reference solver를 실행하지 않는다.
-- Abaqus reference CSV 파일을 생성하거나 수정하지 않는다.
-- reference tolerance를 다시 판정하지 않는다.
-- release readiness를 승인하지 않는다.
-- release notes 또는 final release checklist를 작성하지 않는다.
-
-## 실행 순서
-
-Physics Evaluation Agent는 다음 순서를 따른다.
-
-```text
-EVIDENCE CHECK -> PHYSICS CHECKS -> CLASSIFY -> REPORT
-```
-
-`EVIDENCE CHECK`에서 다음 항목을 확인한다.
-
-- Reference Verification report status가 `pass-for-physics-evaluation`인지 여부
-- checked solver HDF5 file: `<solver output directory>/results.h5`
-- checked feature-declared Abaqus reference CSV files
-- optional FESA deterministic CSV view derived from `results.h5` for review only
-- compared quantities
-- model purpose
-- documented physical expectations
-- sign convention
-- units and coordinate system
-- output location and component naming
-
-## Physics Checks
-
-- `global equilibrium`: 적용 하중, 반력, sign convention이 문서화된 경우 전체 힘/모멘트 평형을 검토한다.
-- `reaction consistency`: constrained DOF와 reaction component가 경계조건과 일관적인지 검토한다.
-- `displacement direction`: 하중 방향, 구속조건, 예상 변형 모드와 변위 부호/방향이 맞는지 검토한다.
-- `symmetry`: symmetry, antisymmetry, expected zero component가 모델 목적과 일치하는지 검토한다.
-- `element force balance`: element internal force가 외력/반력 균형 또는 부호 일관성을 만족하는지 검토한다.
-- `stress/strain`: stress/strain 부호, component, coordinate system, output location이 모델 expectation과 일치하는지 검토한다.
-- `rigid body mode`: 불완전 구속, 비정상적으로 큰 변위, near-zero stiffness 징후를 검토한다.
-- `energy/residual`: `csv/energy_or_residual.csv` 또는 residual output이 있을 때 energy balance, residual trend, convergence sanity를 검토한다.
-- `model coverage`: reference model이 claimed feature를 충분히 검증하는지 검토한다.
-
-## Failure Classification
-
-- `equilibrium-failure`: 전체 하중-반력 또는 모멘트 평형이 기대와 다르다.
-- `reaction-inconsistency`: constrained DOF reaction이 boundary condition 또는 load path와 일관되지 않는다.
-- `displacement-direction-failure`: 변위 방향 또는 부호가 하중/구속조건과 물리적으로 맞지 않는다.
-- `symmetry-failure`: expected symmetry, antisymmetry, zero component가 깨졌다.
-- `stress-location-failure`: stress/strain output location 또는 component 해석이 물리 expectation과 맞지 않는다.
-- `element-force-inconsistency`: element internal force balance 또는 sign이 일관되지 않는다.
-- `rigid-body-mode-suspected`: rigid body mode 또는 under-constrained model 징후가 있다.
-- `nonfinite-result`: NaN 또는 infinite value가 있다.
-- `model-coverage-gap`: reference model이 기능을 충분히 검증하지 못한다.
-- `upstream-contract`: physical expectation, sign convention, unit, coordinate, output location 계약이 누락 또는 충돌한다.
-- `environment`: 로컬 실행/읽기 환경 문제로 평가가 불가능하다.

-- `needs-io-decision`: output location, component naming, sign convention, unit, coordinate mapping이 evaluation을 막는다.
-- `needs-upstream-decision`: physical expectation, sign convention, model purpose, acceptance criterion이 누락 또는 충돌한다.
-- `blocked`: 사용자 또는 Coordinator Agent 결정 없이는 안전하게 진행할 수 없다.
-
-## 품질 기준
-
-- Reference Verification report가 `pass-for-physics-evaluation`이 아니면 physics pass를 판정하지 않는다.
-- documented expectation이 없는 항목은 `skipped`로 두며 expanded portfolio나 calibration을
-  새 gate로 만들지 않는다. Feature-required expectation 자체가 누락된 경우에만
-  `needs-upstream-decision` 또는 `needs-reference-model`을 사용한다.
-- 평형 검토는 적용 하중, 반력, element/internal force sign convention이 문서화된 경우에만 수행한다.
-- stress/strain 검토는 output location, component naming, coordinate system, units가 정의된 경우에만 수행한다.
-- FESA `results.h5`, Abaqus reference CSV files, optional FESA debug CSV view는 읽기 전용 evidence로만 사용한다.
-- pass는 Release Agent로 넘길 수 있다는 뜻이며 release readiness 승인이 아니다.

+# FESA Agent/Skill 개발 프로세스 통합 설계
+
+## Metadata
+
+- date: 2026-08-15
+- status: approved-design
+- scope: FESA 개발 workflow, custom agent, project-local skill, agent 산출물 배치
+
+## 목표
+
+FESA 기능 개발 workflow를 요구사항 단위로 단순화한다. 중복된 agent와 skill을 실제로
+병합하고, `coordinator-agent`를 유일한 main agent로 두며, 모든 단계별 산출물을
+`docs/<feature-id>/`에 모은다.
+
+이 변경은 개발 운영 계약만 바꾼다. Solver C++ 구현, CMake/CTest target, Harness executor,
+hook 동작, Abaqus reference artifact와 승인된 FEM 기능 계약은 변경하지 않는다.
+
+## 핵심 결정
+
+1. 기존 reference model 계약 준비 단계는 Numerical Review 단계에 병합한다.
+2. 기존 Build/Test와 Reference Comparison 단계는 C++ Implementation 단계에 병합한다.
+3. 병합된 단계의 agent와 skill도 각각 하나로 병합한다.
+4. Agent 수를 줄이되 build/test와 reference comparison 증거 문서는 별도로 유지한다.
+5. 모든 agent 산출물은 `docs/<feature-id>/` 아래에 둔다.
+6. `coordinator-agent`는 main agent이고 나머지 agent는 Coordinator가 호출하는 sub-agent다.
+7. `correction-agent`는 정규 단계가 아니라 반복되거나 원인이 불명확한 실패를 다루는
+   재작업 sub-agent로 유지한다.
+
+## 단순화된 개발 프로세스
+
+| 단계 | 담당 sub-agent | 필수 skill | 산출물 |
+| --- | --- | --- | --- |
+| 1. 요구조건 | `requirement-agent` | `fesa-requirements-baseline` | `requirements.md` |
+| 2. 연구 | `research-agent` | `fesa-research-evidence`, 필요 시 `fem-theory-query` | `research.md` |
+| 3. 정식화 | `formulation-agent` | `fesa-formulation-spec` | `formulation.md` |
+| 4. 수치 검토 + reference model 계약 | `numerical-review-agent` | 확장된 `fesa-numerical-review` | `numerical-review.md`, `reference-model.md` |
+| 5. I/O 정의 | `io-definition-agent` | `fesa-io-contract` | `io.md` |
+| 6. 구현 계획 + C++ 구현 + build/test + reference comparison | `implementation-planning-agent`, `implementation-agent` | 확장된 `fesa-cpp-msvc-tdd`와 계획 시 project-local `harness` | `implementation-plan.md`, `implementation-report.md`, `build-test.md`, `reference-comparison.md` |
+| 7. 물리 검토 | `physics-evaluation-agent` | `fesa-physics-sanity` | `physics-evaluation.md` |
+| 8. 배포 준비 | `release-agent` | `fesa-release-readiness` | `release.md` |
+
+`coordinator-agent`는 위 단계 밖에서 전체 workflow와 handoff를 관리하고
+`coordination.md`를 소유한다. `correction-agent`는 Coordinator가 재작업을 요청할 때만
+`corrections.md`에 원인, 수정, 재검증 결과를 추가한다.
+
+## Agent 통합
+
+### Numerical Review 통합
+
+`reference-model-agent`의 책임을 `numerical-review-agent`에 흡수하고
+`.codex/agents/reference-model-agent.toml`을 제거한다.
+
+병합된 Numerical Review Agent는 다음 두 판단을 함께 소유한다.
+
+- 정식화의 차원, 부호, 좌표 변환, Jacobian, 적분, locking, rigid-body mode와 검증 준비도
+- 기존 reference input/CSV의 존재, 비교량, blocking/warning 정책, source identity/component,
+  row precheck와 승인된 tolerance
+
+기존 Reference Model Agent가 I/O 문서를 입력으로 요구하던 순환 의존성은 제거한다.
+`reference-model.md`는 exact input/CSV, 비교량, source identity/component와 tolerance를
+확정한다. 다음 I/O 단계가 이를 소비해 `io.md`에서 최종 HDF5 dataset projection과 CSV
+column mapping을 정의한다.
+
+### Implementation 통합
+
+`build-test-executor-agent`와 `reference-verification-agent`의 책임을
+`implementation-agent`에 흡수하고 다음 파일을 제거한다.
+
+- `.codex/agents/build-test-executor-agent.toml`
+- `.codex/agents/reference-verification-agent.toml`
+
+병합된 Implementation Agent는 한 단계 안에서 다음 순서를 완료한다.
+
+```text
+RED -> observed failure -> minimal GREEN -> focused VERIFY
+    -> full MSVC x64 Debug build/CTest -> reference artifact check
+    -> blocking/warning reference comparison -> report
+```
+
+하나의 agent가 수행하더라도 증거는 다음 세 문서로 분리한다.
+
+- `implementation-report.md`: 구현 범위, RED/GREEN/VERIFY, 코드 변경과 traceability
+- `build-test.md`: 환경, 명령, exit code, 실패 분류와 CTest 결과
+- `reference-comparison.md`: artifact inventory, row identity, tolerance와 quantity별 결과
+
+Implementation 단계의 최종 성공 상태는 `pass-for-physics-evaluation`이다. Compile, link,
+ordinary test 또는 명확한 implementation-owned mismatch는 Implementation Agent가 먼저
+수정한다. 같은 failure classification이 반복되거나 원인이 불명확하면 Coordinator가
+`correction-agent`를 호출한다.
+
+## Skill 통합
+
+### Numerical Review skill
+
+`fesa-reference-models`의 reference inventory, comparison scope, identity, row precheck,
+tolerance와 handoff 계약을 `fesa-numerical-review`에 흡수한다. 다음 디렉터리를 제거한다.
+
+- `.codex/skills/fesa-reference-models/`
+
+확장된 `fesa-numerical-review`는 `numerical-review.md`와 `reference-model.md`를 모두
+산출하고 I/O Definition Agent에 두 문서를 handoff한다.
+
+### C++ TDD skill
+
+`fesa-reference-comparison`의 `ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT`, deterministic
+row matching, nonfinite/누락/추가/중복 row rejection과 tolerance 적용 계약을
+`fesa-cpp-msvc-tdd`에 흡수한다. 다음 디렉터리를 제거한다.
+
+- `.codex/skills/fesa-reference-comparison/`
+
+확장된 `fesa-cpp-msvc-tdd`는 구현 계획, TDD 구현, MSVC build/CTest, failure correction과
+reference comparison을 하나의 구현 단계 절차로 정의한다. Project-local `harness`의 계획
+승인, phase materialization, executor와 hook 계약은 변경하지 않는다.
+
+통합 후 FESA workflow skill은 다음 8개다.
+
+- `fesa-requirements-baseline`
+- `fesa-research-evidence`
+- `fesa-formulation-spec`
+- `fesa-numerical-review`
+- `fesa-io-contract`
+- `fesa-cpp-msvc-tdd`
+- `fesa-physics-sanity`
+- `fesa-release-readiness`
+
+`fem-theory-query`와 project-local `harness`, `review`는 별도 보조 skill로 유지한다.
+
+## Agent 계층과 Coordinator Orchestration
+
+통합 후 `.codex/agents/`에는 main agent 1개와 sub-agent 10개가 남는다.
+
+- main: `coordinator-agent`
+- sub-agents: `requirement-agent`, `research-agent`, `formulation-agent`,
+  `numerical-review-agent`, `io-definition-agent`, `implementation-planning-agent`,
+  `implementation-agent`, `correction-agent`, `physics-evaluation-agent`, `release-agent`
+
+Coordinator는 다음 순서로 동작한다.
+
+```text
+INTAKE -> STATE AUDIT -> WORKLIST UPDATE -> SUB-AGENT DISPATCH
+       -> EVIDENCE CHECK -> GATE DECISION -> STATUS REPORT
+```
+
+Coordinator는 한 번에 다음 유효 단계의 owner만 호출한다. Sub-agent는 전달받은 단계와
+산출물만 처리하고 peer agent를 직접 호출하거나 다음 단계로 진행하지 않는다. 완료 후
+산출물 경로, status, 핵심 evidence, blocker를 Coordinator에 반환한다.
+
+`docs/<feature-id>/coordination.md`는 다음 정보를 중심으로 작성한다.
+
+- feature scope와 현재 목표
+- 8단계 worklist
+- 단계별 owner, 상태, 산출물 경로와 완료 evidence
+- 현재 실행 중인 sub-agent와 다음 handoff
+- blocker, 사용자 결정과 failure classification
+- correction attempt count와 반복 실패 stop condition
+- gate transition decision log와 최종 workflow closure
+
+Worklist 항목 상태는 `pending | in-progress | passed | needs-rework | blocked`만 사용한다.
+동일 failure classification이 두 번 반복되면 자동 재작업을 중단하고 전체 workflow를
+`needs-user-decision` 또는 `blocked`로 전환한다.
+
+## Gate 계약
+
+1. Requirements gate: `requirements.md`가 승인된 범위, acceptance criteria, 검증량과
+   tolerance를 가진다.
+2. Research gate: `research.md`가 필요한 이론과 검증 evidence를 제공한다.
+3. Formulation gate: `formulation.md`가 구현 가능한 수치 계약을 제공한다.
+4. Numerical/reference gate: `numerical-review.md`와 `reference-model.md`가 모두 통과한다.
+5. I/O gate: `io.md`가 reference identity를 authoritative HDF5 dataset과 연결한다.
+6. Implementation gate: 구현 계획, RED/GREEN evidence, MSVC build/CTest와 blocking reference
+   comparison이 모두 통과한다.
+7. Physics gate: `physics-evaluation.md`가 `pass-for-release-agent`다.
+8. Release gate: `release.md`가 `ready-for-release`이고 Coordinator가 closure를 기록한다.

+산출물이 필요하지 않았거나 기존 workflow에서 생성되지 않은 경우 빈 placeholder 문서를
+만들지 않는다. `corrections.md`는 실제 correction이 발생할 때만 생성한다.
+
+## 기존 문서 마이그레이션
+
+현재 agent별 폴더의 기능 문서를 다음 두 요구사항 폴더로 이동한다.
+
+- `docs/linear-static-3d-euler-beam/`
+- `docs/linear-static-mitc4-shell/`
+
+파일 내용과 당시 `owner_agent`, status, numerical verdict는 역사적 evidence이므로 바꾸지
+않는다. 내부 문서 경로만 새 위치로 갱신한다. 삭제된 agent 이름이 기존 evidence의
+소유자로 기록된 경우도 그대로 보존한다.
+
+기존 `docs/requirements/`, `docs/research/`, `docs/formulations/`,
+`docs/numerical-reviews/`, `docs/io-definitions/`, `docs/reference-models/`,
+`docs/implementation-plans/`, `docs/build-test-reports/`, `docs/corrections/`,
+`docs/reference-verifications/`, `docs/physics-evaluations/`, `docs/releases/`,
+`docs/coordination/`의 기능 문서와 필요한 내부 링크를 옮긴 뒤 agent별 README는 제거한다.
+공통 운영 계약은 `AGENTS.md`, `docs/SOLVER_AGENT_DESIGN.md`,
+`docs/SOLVER_SKILL_DESIGN.md`에 통합한다.
+
+기존 두 기능은 `ready-for-release` evidence를 가지고 있으므로 새 `coordination.md`에서
+`completed`로 inventory한다. 누락된 과거 산출물을 새 문서로 꾸미거나 새 workflow를
+소급 실행하지 않는다.
+
+다음 항목은 이동하거나 변경하지 않는다.
+
+- `docs/PRD.md`, `docs/ARCHITECTURE.md`, `docs/ADR.md`
+- `docs/reference-papers/`와 기타 공통 기술 문서
+- `reference/` 아래의 Abaqus input/CSV artifact
+- `phases/`의 실행 상태와 Harness 실행 결과 본문. 이동된 문서를 가리키는 path reference만
+  기계적으로 갱신할 수 있다.
+- Solver C++ source, tests, CMake/CTest configuration
+
+## 문서와 참조 갱신
+
+현재 실행 계약에서는 제거된 agent/skill과 기존 agent별 산출물 경로를 사용하지 않는다.
+다음 파일군을 새 workflow와 `docs/<feature-id>/` 경로로 갱신한다.
+
+- `AGENTS.md`
+- `.codex/agents/*.toml`
+- `.codex/skills/*/SKILL.md`와 대상 `agents/openai.yaml`
+- `docs/SOLVER_AGENT_DESIGN.md`
+- `docs/SOLVER_SKILL_DESIGN.md`
+- 이동한 기능 문서의 내부 링크
+- 기존 경로를 입력으로 사용하는 관련 계획, spec, phase 문서
+
+역사적 산출물 본문에 기록된 과거 agent 이름과 status는 stale reference 검사 대상에서
+제외하지만, 새 입력 경로를 가리키는 링크는 유효해야 한다.
+
+## 검증 전략
+
+`tests/test_agent_skill_workflow_contract.py`를 추가해 다음 정적 계약을 검증한다.
+
+- 남은 agent 파일 집합이 main 1개와 sub-agent 10개인지 확인
+- 제거 대상 agent 3개와 skill 2개가 존재하지 않는지 확인
+- Coordinator가 main 역할과 `docs/<feature-id>/coordination.md` worklist를 정의하는지 확인
+- 모든 다른 agent가 sub-agent 역할과 Coordinator handoff를 정의하는지 확인
+- 병합 대상 skill의 핵심 workflow와 output contract가 destination skill에 존재하는지 확인
+- 현재 실행 계약에 제거된 agent/skill 이름이나 기존 agent별 출력 경로가 없는지 확인
+- 모든 TOML이 parse되고 각 skill의 frontmatter와 UI metadata가 유효한지 확인
+
+검증 명령은 다음과 같다.
+
+```powershell
+uv run --with pytest python -m pytest -v -rs
+python <skill-creator>/scripts/quick_validate.py .codex/skills/<remaining-skill>
+git diff --check
+```
+
+`quick_validate.py`는 남아 있는 project-local skill 각각에 실행한다. 이번 변경은 C++
+production과 CMake/CTest를 수정하지 않으므로 MSVC build와 CTest는 필수 검증 범위가 아니다.
+
+## 완료 기준
+
+- 8단계 workflow가 `AGENTS.md`, agent config와 설계 문서에서 동일하다.
+- 삭제 대상 agent와 skill이 제거되고 모든 책임과 quality gate가 destination에 보존된다.
+- `coordinator-agent`가 main agent로서 sub-agent dispatch와 worklist 갱신을 소유한다.
+- 모든 새 산출물 경로가 `docs/<feature-id>/` 규칙을 따른다.
+- 기존 기능 문서가 새 폴더에 모이고 역사적 verdict가 보존된다.
+- 자동 계약 테스트, 전체 Python pytest, skill validation과 `git diff --check`가 통과한다.
