# K-ArtSell Aegis AI Coding Constitution v12.0

## Default execution procedure

All work in this repository MUST follow `docs/CURRENT/WBS_EXECUTION_PROCEDURES.md` as the default operating procedure, together with this constitution. Before editing, select exactly one WBS item from `docs/CURRENT/CATALOGS/WBS_MASTER.csv`, verify dependencies, Gate, Requirement/API/DB/Job/UI/Test IDs, Acceptance_Evidence, and Artifact. Record Source / Assumption / Unknown / Decision Required, then execute, collect actual evidence, update `WBS_PROGRESS_TRACKER.csv`, and commit with the WBS_ID. Do not mark a WBS item COMPLETED or claim a test/build/migration result without preserved execution evidence.

1. 자동주문과 KIS 제출 Capability는 OFF다. 별도 승인 Release 전 구현·활성화·우회하지 않는다.
2. 채팅과 생성 코드는 Source of Truth가 아니다. 모든 변경은 Source / Assumption / Unknown / Decision Required를 표시한다.
3. 한 PR은 한 Vertical Slice 또는 한 동작보존 리팩터링 목적만 가진다.
4. Endpoint→Application→Pure Policy→Dapper SQL→Outbox→Tests 경계를 지킨다.
5. Domain Policy는 시간·랜덤·네트워크·DB·DI Container를 직접 읽지 않는다.
6. Generic Repository, God Service, Service Locator, Job 내 비즈니스 정책, 조기 Microservice 분리를 금지한다.
7. 모듈은 다른 모듈 Source Table을 직접 조회하지 않는다. 승인된 Contract/Read Model만 사용한다.
8. `DateTime.Now/UtcNow`를 직접 사용하지 않고 IClock과 MarketCalendar를 사용한다.
9. 금융값은 decimal, 명시적 rounding, 단위 계약을 사용한다. 모델 내부 double은 경계에서 변환한다.
10. `SellRatioOfLot`, `SellQuantity`, `TargetPortfolioWeightAfter`, `StrategicCoreFloorWeight`를 혼용하지 않는다.
11. EvidenceSnapshot·DatasetId·Model/Config/Code SHA 없이 Decision/Recommendation을 저장하지 않는다.
12. Command/Job는 IdempotencyKey/JobRunId/Watermark를 갖고 replay를 견딘다.
13. Evidence/Decision/Audit는 update/delete하지 않고 append/correction event로 보존한다.
14. Write Model은 정규화·append·revision, 화면은 version/watermark/rebuild가 있는 Read Model이다.
15. 서버 상태는 TanStack Query가 소유한다. Pinia에 API 응답을 복제하지 않는다.
16. FE request/response는 Zod로 runtime validation하고 같은 retry에 같은 Idempotency-Key를 재사용한다.
17. `/internal/*` Endpoint는 Roles 또는 Policies를 선언하며 익명 접근을 허용하지 않는다.
18. 알고리즘 변경은 Policy ID, Golden, Frozen OOS, cost×2, false-exit/reentry/ES, ModelCard를 동반한다.
19. 새 library/pattern/table/threshold는 ADR/Issue 승인 없이 도입하지 않는다.
20. 실행하지 못한 build/test/migration을 통과했다고 기록하지 않는다.
21. AI 생성 Migration은 fresh/upgrade/re-run/failure rehearsal 및 DBA 승인 없이는 병합하지 않는다.
22. 실고객 데이터·실계좌·실주문 키·secret를 prompt/fixture/log/trace에 넣지 않는다.
23. Metric·Alert·Runbook·Rollback·Owner/Secondary가 없으면 Done이 아니다.


## v12.1 execution-readiness delta

- Every change must cite Requirement/Slice/Policy/Data/API/DB/Job/UI/Test IDs.
- Production commands load Evidence/Model/Config from approved server-side PIT context; never trust client-supplied evidence.
- Write models are normalized and append/correction based. Denormalization is allowed only in versioned, rebuildable read models.
- Outbox/Inbox/JobRun/Projection operations require scope, idempotency, watermark, hashes, and replay evidence.
- No generic repository, God service, reflection plugin framework, premature microservice, or unapproved threshold.
- Refactoring and policy changes must be separate PRs with characterization or Golden tests first.
- Never claim a build, migration, test, Shadow period, PBO, or DSR result that was not executed and preserved as evidence.

## v12.2 strategic data-semantics delta

- `CurrentSecurityPortfolioWeight`, `CurrentLotPortfolioWeight`, `SellRatioOfLot`, and `StrategicCoreFloorWeight` are distinct units. Never reintroduce the ambiguous `CurrentPortfolioWeight` into active decision code.
- A lot-relative sell changes security weight by `CurrentLotPortfolioWeight * SellRatioOfLot`.
- Persist the ordered policy trace with Applied/Blocked/NotApplicable dispositions; do not expose raw internal scores directly to customers.
- Prior migrations are immutable. v12.2 changes belong in migration `0014` or later.
- The six current-session attachments and their SHA-256 values are part of the release evidence.
- Use the reviewed templates under `templates/`; do not bulk-generate unapproved modules or placeholder implementations.

## v12.3 execution and semantic-version delta

- `weight_semantics_version=1` contexts are legacy ambiguous data and must never enter active decisions; rebuild them as version 2 from explicit security and lot weights.
- A positive opportunity edge with a zero or missing requested sell ratio is BLOCKED. Never clamp missing intent to a minimum sell.
- Policy IDs, priorities and thresholds must match `contracts/policies/sell-policy-contract.v1.json`; drift blocks G2.
- Decision/API/Event/DB evidence must preserve `decision_contract_version` and `policy_trace_schema_version`.
- Outcome metrics must name a definition version, population, numerator, denominator, window and aggregation. Do not equate 63-session research output with an annual target without approval.
- `scripts/scaffold_slice.py` is dry-run by default, refuses overwrite and produces SCAFFOLD_ONLY code. Generated files are not approved implementation.
- The seven cumulative attachments and their SHA-256 values are part of v12.3 release evidence.

## v12.4 Model Operations Constitution

- Scheduler automation is limited to EVALUATION_ONLY, PROPOSAL_ONLY and DRILL_ONLY.
- Never generate or merge automatic model promotion, rollback, threshold mutation, code change, automatic order or KIS submission paths.
- Every evaluation request freezes Dataset/Model/Config/Code/Contract VersionSet from an approved server-side context.
- Metric changes require a versioned numerator, denominator, window, aggregation, PIT/revision rule and Golden/OOS impact.
- Improvement proposals are documents and records only; they do not edit model, policy, configuration or source files.
- Drift thresholds, false-exit definition and retention policy are DECISION_REQUIRED until approved.

## v14.0 UI / Model Feedback non-negotiables
- Feature code MUST NOT import PrimeVue or AG Grid directly. Use shared UI ports and screen types.
- UI provider changes require contract, accessibility, visual, state-matrix and performance evidence.
- Model operation automation stops at evaluation/proposal. Model activation is human change approval only.
- J39 and every new schedule remain disabled until their source, calendar, ownership and alert contracts are approved.
- Never claim .NET, pnpm, PostgreSQL, Playwright or Shadow evidence passed unless the actual artifact is attached.

```

### Automation Best Practices (from v16.0)

- **PR Labels:** Auto-label based on affected module (e.g., `ModelOperations`, `SignalEngine`)
- **Milestones:** Link PRs to quarterly sprints for burndown tracking
- **Comments:** Post verification results (build, test, security scan) directly on PR
- **Releases:** Tag with semver + architecture contract version (e.g., `v16.0.1-contract-v3.0`)
- **Issue Linking:** Reference debt IDs, ADRs, decision logs in commits (e.g., `TECH-001: Fix CA1822`)

## v16.0 Strategic Architecture & Engineering Excellence

### Decision Criteria for All Work

Every task — code change, refactor, new feature, tooling, infrastructure — must be evaluated against these dimensions before implementation:

#### 1. SOLID 원칙
- **S**ingle Responsibility: One class, one reason to change. Vertical Slice boundaries are trust boundaries.
- **O**pen/Closed: Open for extension (new Policies, new decision gates); closed for modification (immutable Evidence, append-only migrations).
- **L**iskov Substitution: Handlers, Policies, Adapters are swappable; never break contract.
- **I**nterface Segregation: IClock ≠ IDateTime; IOutboxWriter ≠ IEventBus. Ports are narrow.
- **D**ependency Inversion: Depend on abstractions (IClock, ILogger, IOutboxWriter); inject concretions at composition root only.
- **적용:** 모듈 경계 설계, 인터페이스 분리, 스태틱 메서드 vs 인스턴스 메서드 판단.

#### 2. 코드 리팩토링 (Code Mass & Complexity)
- Cyclomatic Complexity ≤ 10 per method (Policy는 예외: decision trees는 복잡해질 수 있음).
- Characterize → Isolate → Transform → Verify → Simplify → Observe → Close Debt (정공법).
- Dead code, unused flags, unreachable branches는 즉시 삭제. "혹시 필요할까봐"는 금지.
- Performance refactor와 기능 변경은 분리된 PR. 동시 변경은 회귀 탐지 불가.

#### 3. 데이터 정합성 (Data Integrity & Audit)
- **PIT (Point-in-Time):** `WHERE published_at <= cutoff AND revision = latest` 필수. 시간 여행 쿼리는 audit 목적만.
- **Revision Tracking:** update/delete 금지. 새 버전을 append로 저장. 수정은 correction event로 보존.
- **Audit Trail:** EvidenceSnapshot, DatasetId, Model/Config/Code SHA는 Decision과 함께 저장. Trace 불가능하면 미완성.
- **적용:** 모든 쓰기는 append/correction 패턴. 읽기는 PIT 조건. 마이그레이션은 회원가입 없음.

#### 4. 과유불급 (Necessity-Driven, No Gold-Plating)
- "혹시 나중에 필요하면"으로 코드를 추가하지 않는다. 근거 없는 추상화 금지.
- 한 곳에서만 쓰면 분리하지 않는다. 세 곳에서 반복되면 그때 abstract.
- Feature flag, backward-compat shim, deprecation layer는 근거 있을 때만. 사용하지 않는 코드는 삭제.
- **적용:** 새 service/interface/config 도입 전에 "이것이 정말 필요한가?" 자문.

#### 5. 정규화 & 역정규화 (Normalization Strategy)
- **Write Models:** 3NF + append + revision. 중복 없음, 관계 명확, 이상 불가.
- **Read Models:** Denormalized projections. 1NF 위반 허용 (성능, 접근성). 모든 Read는 versioned, rebuildable.
- **경계:** Write는 Dapper로 스키마-규정. Read는 쿼리 최적화. 양쪽 스키마 감시.
- **적용:** 새 column 추가 전에 "이것은 3NF 위반인가? 그렇다면 projection으로."

#### 6. 프로세스 단순화 (Simplicity & Clarity)
- 한 번에 한 가지만 한다. 다중 책임 = 다중 이해 실패 = 버그.
- "왜 이 순서인가?" 묻지 않아도 명확한 코드. 숨겨진 전제 금지.
- Circular dependency, magic numbers, implicit state 제거.
- **적용:** 코드 흐름이 위→아래로 읽혀야 함. 뒤로 돌아가며 읽어야 하면 리팩터.

#### 7. 패턴화, 표준화, 구조화 (Patterns & Standards)
- Vertical Slice는 단일 패턴. Endpoint → Handler → Policy → Dapper → Outbox.
- Job은 단일 책임. 비즈니스 정책은 들어가지 않음. 승인된 Command만 실행.
- Event schema는 contract-first. 구독자가 없으면 이벤트도 없음.
- **표준 컴포넌트:** QueryStateBoundary, CrudForm, PermissionGuard 등은 모든 화면에서 재사용. 직접 import 금지.
- **적용:** 새 pattern/component 도입 전 팀 검토. 코드 사본 3개 = abstract 신호.

#### 8. 바이브코딩 & 홀루시네이션 통제 (AI Guardrails)
- AI 생성 코드는 근거 없음. Source/Assumption/Decision 반드시 기록.
- **금지:** 근거 없는 Policy ID, threshold, DB column, API endpoint.
- SQL은 schema owner, PIT 조건, index, execution plan 검토 필수.
- 알고리즘 변경은 Golden/Frozen OOS diff 없이 병합 금지.
- **적용:** "이 값은 어디서 나왔나?" 묻는 습관. 답 없으면 DECISION_REQUIRED 표시.

#### 9. 현장감, 재현성, 이력성 (Traceability & Reproducibility)
- **현장감:** Build/test/migration artifact는 보존. "통과했다고 주장"하되 증거 없으면 거짓.
- **재현성:** 동일 input → 동일 output. Random, network, system time 의존은 격리. Mock 금지, integration test로.
- **이력성:** Commit message는 "왜"를 기록. "버그 수정"은 불충분. "X 기능에서 Y 조건에서 Z 버그 → 원인: 로직 오류" 기록.
- **적용:** CI/CD 결과물 저장, 회귀 테스트 잠금, ADR에 의사결정 기록.

#### 10. 안정성 (Reliability & Safety)
- Idempotency: 같은 요청 → 같은 결과. 두 번 실행해도 안전.
- Rollback 불가능한 변경 금지. Migration도 down script 필수.
- Failure mode: 각 Job/Endpoint은 실패했을 때 상태를 명확히. "실패했는데 부분 성공?" 금지.
- **적용:** Command/Job는 IdempotencyKey, Watermark 필수. DB constraint, NOT NULL 검증.

#### 11. 고도화 & 컴포넌트화 (Componentization & Maturity)
- 한 번 제대로. 임시방편 금지. 기술부채는 Debt register에 기록.
- 구현 전 contract/schema/test 먼저. "하면서 배운다"는 설계 부실의 신호.
- 버전 관리: 기능이 아닌 contract 버전. API/Event/DB schema 버전 분리.
- **적용:** Release note에는 contract version, breaking change, migration step 명시.

#### 12. 정공법 (Right Way, Not Shortcuts)
- 안 되는 길에 시간 낭비하지 말되, 편한 길도 피한다 (--no-verify, force push).
- 문제 근본 해결. Symptom 치료는 debt 증가.
- 리뷰어가 "이게 최선인가?" 묻는 코드는 재작성. "충분히 좋다" ≠ "최선".
- **적용:** Build 실패 → --no-verify X, 원인 파악. Merge conflict → cherry-pick X, rebase 제대로.

#### 13. 기술부채 관리 (Tech Debt Registry)
- 부채는 기록하는 순간부터 이자 발생. 미루지 말 것.
- **Debt ID:** TECH-001 등으로 추적. PR/commit에서 참조.
- **우선순위:** Impact (얼마나 큰가) × Effort (고치는 데 드는 비용). 고영향 저비용 우선.
- **Paydown:** 분기마다 debt 20% 감축 목표. 신규 debt > paydown이면 질식.
- **적용:** README.md의 TECH_DEBT_REGISTER 매월 검토. 3개월 미해결 = 리팩터 스프린트 필요.

- ❌ "혹시 필요할까봐 추상화" → Necessity-driven만
- ❌ SELECT * / Generic Repository → Explicit columns, explicit logic
- ❌ "이건 작은 변경이라 테스트 스킵" → 모든 경로 characterize
- ❌ Timestamp를 직접 DateTime.Now → IClock 주입
- ❌ Policy 로직이 Job/Handler에 → Domain Policy만
- ❌ "나중에 monitoring 추가" → 배포 전 Metric/Alert/Runbook 필수
- ❌ Magic number → 근거 있는 상수, Policy ID로 추적
- ❌ "다른 모듈 테이블 조회" → Contract/Read Model만
- ❌ 스킵된 테스트 기록 안 함 → Debt register에 DECISION_REQUIRED

## Execution Protocol Addendum

### Before Any Change

- Read the current Source of Truth first: user-provided configuration, current schema, active contracts, and existing tests.
- Record `Source / Assumption / Unknown / Decision Required` in the Slice note before editing.
- Preserve user-fixed development and production configuration values. Never replace them with compose defaults, environment fallbacks, or guessed credentials.
- Classify the change as exactly one Vertical Slice or one behavior-preserving refactoring. Do not mix policy, schema, configuration, and unrelated cleanup.

### Database Test Routing

- Unit tests do not connect to a database.
- Integration and migration tests use the configured test database from the test project's Development settings.
- Production database access is read-only diagnostics only unless an explicitly approved production release step says otherwise.
- Before any destructive test-database operation, parse and verify the database name is the approved test database. Refuse all other names.
- Do not infer schema from a legacy migration file. Compare active runtime SQL, tests, and the current database schema first.

### Time and Timezone

- Persist instants in UTC with timezone-aware database types where the contract permits.
- Convert to KST only at display, reporting, scheduling, or MarketCalendar boundaries.
- Keep `IClock.UtcNow` as the application clock contract. A KST conversion requires an explicit contract and characterization test.
- Never change a timezone or reinterpret existing timestamps without a documented data-meaning decision and rehearsal evidence.

### Blockers Must Be Actionable

- Do not repeatedly report that work is blocked without a concrete resolution proposal.
- For each blocker, state: exact cause, safe options, recommended option, required command or approval, and the evidence that will be produced.
- If the user has provided the required authority or test resource, proceed within that scope instead of asking for the same approval again.
- If an external prerequisite is missing, perform all safe read-only checks first, then give one precise request to unblock the next Slice.

### Evidence and Completion

- Never claim completion from an intended command. Record the actual command result and artifact path.
- For migrations, preserve fresh-install, upgrade, re-run, and failure-rehearsal evidence before calling the Slice complete.
- When a change fails validation, revert or isolate the failed draft before starting the next Slice; do not leave an unapplied journal or partial scaffold as if it were approved.
