fix: Add explicit MIME type configuration for static files

- Configure FileExtensionContentTypeProvider for Blazor assets - Set correct MIME types: .wasm, .js, .mjs, .json, .svg, .woff, .woff2 - Enable ServeUnknownFileTypes for flexibility - Fixes 'Empty MIME type' error on Blazor module loading - Resolves ReconnectModal and dotnet.js loading failures MIME type mapping: - .wasm → application/wasm - .js → application/javascript - .mjs → application/javascript - .json → application/json - .svg → image/svg+xml - .woff → font/woff - .woff2 → font/woff2 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+     - price_status, orderbook_status, short_sale_status
+     - collection_as_of (ISO 8601 KST)
+  2. 타입 안전성
+     - nullable fields는 `?` 명시 (price: double?, status: string)
+  3. Serialization 지원
+     - [JsonPropertyName] attribute로 Python 필드명 맵핑
+  4. 테스트 가능성
+     - 기본 생성자, 공개 속성

+## 🎯 성공 기준 (데이터 증빙)
+
+### 기능 동등성
+```
+✅ Python vs C# 동등 검증:
+  1. 입출력 시그니처
+     collect_to_sqlite(...) → RunCollectionAsync(...)
+     같은 파라미터, 같은 반환값 구조
+  
+  2. 데이터 흐름
+     GatherTradingData.json (입력)
+     → 시드 데이터 파싱
+     → KIS API 호출 (3개 endpoint)
+     → 데이터 정규화
+     → DB 저장 (3개 테이블)
+     → JSON 출력 (Temp/kis_data_collection_v1.json)
+  
+  3. 에러 처리
+     Python test_kis_data_collection_v1.py 모든 케이스 통과
+```
+
+### 코드 품질
+```
+✅ SOLID 원칙:
+  1. Single Responsibility ✓
+     - DataCollectionService: 오케스트레이션만
+     - PriceDataNormalizer: 정규화만
+     - GatherTradingDataParser: 파싱만
+  
+  2. Open/Closed ✓
+     - IPriceSource 추가 시 기존 코드 수정 X
+     - NaverApiPriceSource 추가 가능
+  
+  3. Liskov Substitution ✓
+     - KisApiPriceSource, NaverApiPriceSource 모두 IPriceSource 준수
+  
+  4. Interface Segregation ✓
+     - IPriceSource: 3 메서드만 (GetPriceDataAsync)
+     - ICollectionOrchestrator: 2 메서드 (RunCollectionAsync, ...)
+  
+  5. Dependency Inversion ✓
+     - 구체적 클래스 X, 인터페이스에 의존
+```
+
+### 테스트 커버리지
+```
+✅ 목표: ≥85% 라인 커버리지
+  1. Unit Tests: 20+ test cases
+     - CoerceFloat (10)
+     - FindFirstValue (8)
+     - GatherTradingDataParser (5)
+     - SourcePriorityResolver (3)
+     - PriceDataNormalizer (3)
+  
+  2. Integration Tests: 5+ scenarios
+     - Happy path
+     - Partial failure
+     - All errors
+     - JSON output
+     - DB persistence
+  
+  3. E2E Tests: 3+ flows
+     - POST /api/collection/run
+     - File creation
+     - DB verification
+```
+
+### 성능 기준
+```
+✅ 성능 목표:
+  1. 단일 종목 수집
+     - 목표: < 2초
+     - KIS API 3개 호출 포함
+  
+  2. 배치 수집 (100개 종목)
+     - 목표: < 120초
+     - 평균 1.2초/종목
+  
+  3. JSON 파일 크기
+     - 목표: < 10MB (100개 종목)
+```
+
+### 호환성 검증
+```
+✅ Python 동등성:
+  1. 입력 형식
+     GatherTradingData.json 구조 100% 호환
+  
+  2. 출력 형식
+     Temp/kis_data_collection_v1.json 구조 100% 동일
+     - JSON 필드명, 타입, 순서
+  
+  3. DB 스키마
+     kis_collection_runs, snapshots, errors 모두 호환
+  
+  4. 에러 처리
+     Python과 동일한 에러 메시지, status 코드
+```

+1. 구현 중 막히면?
+   - WBS 해당 Task의 "성공 규칙" 다시 읽기
+   - Python 원본 코드 라인 번호 재확인
+   - 테스트 케이스로 구현하기 (TDD)
+
+2. 테스트 실패?
+   - Python test 다시 실행 (비교)
+   - 데이터 타입/값 불일치 확인
+   - 로깅 추가해서 디버그

+# WBS-10 보강: .NET Core 마이그레이션 완성 & 상용화 로드맵 (2026-06-30)
+
+> 본 문서는 [docs/ROADMAP_WBS.md](./ROADMAP_WBS.md) 의 **WBS-10(.NET 엔진 고도화)** 을 현 시점 실측 기준으로 재진단하고, 마이그레이션 완성과 단일 사용자 상용 운영에 필요한 잔여 작업을 재정의한다.
+>
+> **작성 배경:** 기존 WBS-10 의 다수 항목이 `완료` 로 표기되어 있으나, 2026-06-30 소스 실측 결과 **표기와 실제 상태 간 괴리**가 확인되었다. 본 문서는 그 괴리를 정리하고 실제 잔여 작업을 추적한다.
+>
+> **의사결정(사용자 확정):** ① 우선순위 = **마이그레이션 완성 우선**, ② 산출물 = **로드맵/WBS 문서**, ③ 인증 모델 = **단일 사용자 + 기본 보호**.
+
+---
+
+## 1. Context — 왜 이 보강이 필요한가
+
+QuantEngine 은 은퇴자산 포트폴리오 운용을 위한 결정론적 퀀트 엔진이다. canonical 권위는 여전히 **Python 구현(219 파일, 24,683 lines)** 에 있고, `.NET 10` 마이그레이션은 Core / Application / Infrastructure / Web / Tools / Tests 6개 프로젝트로 구조화되어 Phase 1(Web UI)·Phase 2(KIS 수집)까지 도달했다.
+
+그러나 다음 세 가지 근본 결손으로 마이그레이션 완료 및 상용 기준에 미달한다.
+
+1. **마이그레이션 미완성** — 도메인 단일 권위가 Python 에 잔존. `PipelineOrchestrator` 가 실제 로직이 아닌 시뮬레이션 스텁. Python↔.NET 패리티가 일부 도메인 계산기에만 존재. GAS 공식 14건 미이관.
+2. **상용 운영 결손** — 소스에 하드코딩 시크릿 잔존, `.gitignore` 의 `bin/obj` 누락으로 빌드 산출물 git 추적, 헬스체크·메트릭·재시도·스케줄러·운영 구성(`appsettings.Production.json`) 부재.
+3. **검증 공백** — KIS→스냅샷→정성매도 전 구간 E2E 와 CI 커버리지 게이트 부재.
+
+---
+
+## 2. 표기 vs 실제 괴리 정리 (2026-06-30 실측)
+
+| 기존 WBS | 기존 표기 | 실측 상태 | 괴리 / 조치 |
+|---|---|---|---|
+| WBS-10.6 파이프라인 오케스트레이터 | **완료** | `PipelineOrchestrator.cs` 가 각 단계를 `Task.Delay(10)` 로만 시뮬레이션. 실제 서비스 호출 없음 | 🔴 **실질 미완성.** → 본 문서 **A1** 로 재추적 |
+| WBS-10.9 보안 강화 | **완료** | `appsettings.json` 은 `Password=;` 처리됨. 그러나 `Program.cs:19` 텔레그램 토큰 평문, `Program.cs:34` DB 패스워드 폴백 평문 잔존. `.gitignore` 에 `bin/obj` 없음 → 산출물 git 추적 | 🔴 **부분 완료(핵심 누락).** → 본 문서 **P0** 로 재추적 |
+| WBS-10.8 데이터 수집 오케스트레이터 | **TODO** | 실제로는 `DataCollectionService.cs`(KIS 수집 오케스트레이션) 구현·커밋됨. 단 파일명/구조가 WBS 기재(`DataCollectionOrchestrator.cs`)와 불일치 | 🟡 **표기 미갱신.** → 본 문서 **A3** 로 정합화 |
+| WBS-10.3~10.5 도메인/공식/하네스 패리티 | 완료 | `DomainParityTests`, `FormulaEngineTests`, `HarnessInjector` 패리티 존재 확인 | ✅ 유효. 단 패리티 범위가 도메인 계산기에 한정 → 수집/정성매도/스냅샷은 미커버 (**A2** 확장) |
+| WBS-10.7 Application 서비스 | 부분 완료 | 4개 서비스 구현 확인 | ✅ 유효 |
+
+> **핵심 시사점:** 기존 WBS-10 은 "완료" 표기가 실제보다 앞서 있다. 특히 보안(10.9)과 파이프라인(10.6)은 표기와 달리 **실질 미완성**이므로, 후속 작업은 표기를 신뢰하지 말고 본 문서의 실측 기준을 따른다.

+- **배경:** UI 표준을 **MudBlazor** 컴포넌트 + **Interactive WebAssembly** 렌더 모드 + **API-First** 로 전환(방침 확정). 기존 Fluent UI v5 / InteractiveServer 는 폐기. 정책은 [CLAUDE.md](../CLAUDE.md) 및 [AGENTS.md](../AGENTS.md) §5b 에 반영 완료.
+- **목표:**
+  - csproj 패키지 교체: `Microsoft.FluentUI.AspNetCore.Components*` 제거 → `MudBlazor` 추가.
+  - 렌더 모드 전환: `Program.cs` 의 `AddInteractiveServerComponents`/`AddInteractiveServerRenderMode` → `AddInteractiveWebAssemblyComponents`/`AddInteractiveWebAssemblyRenderMode`, 클라이언트 프로젝트(`QuantEngine.Web.Client`) 분리.
+  - `App.razor`: Fluent CSS/JS·`FluentDesignSystemProvider` 제거 → MudBlazor `<MudThemeProvider>`/`<MudDialogProvider>`/`<MudSnackbarProvider>` + `MudBlazor.min.css/js` 삽입.

+- **판정:** 개발/운영 구성 분리, 필수 구성 누락 시 명확 오류로 기동 중단.
+
+#### WBS-B2 기본 인증 (단일 사용자 보호)
+- **목표:** 공개 서버 노출 방어용 최소 인증 — 리버스 프록시 Basic Auth 또는 API Key 미들웨어 1종(`/api/*`·UI 보호). 본격 Identity/JWT 는 범위 외.
+- **판정:** 비인증 요청 401, 인증 요청만 수집/조회 가능.

+- **판정:** E2E 1건 이상 그린, 커버리지 임계 미달 시 CI 실패.
+- **파일:** `QuantEngine.Core.Tests/`(통합/E2E), `.gitea/workflows/ci.yml`.
+
+---
+
+## 5. 개선·보완·고도화 제안 (Track A/B 외 권고)
+
+- **결정 재현성 감사:** 동일 입력 → 동일 출력 결정론 검증을 CI 상시 게이트로 편입 ([governance/adr/0003-no-llm-numeric-generation.md](../governance/adr/0003-no-llm-numeric-generation.md) 정신 계승).

+- **장애 단일점 보강:** Naver Cloudflare 403 폴백 경로를 Yahoo/KIS 다중화로 명문화(WBS-A3 연동).
+- **운영 가시성:** 구조화 로깅에 상관관계 ID(correlation id) 추가, 수집 실행별 추적 가능화.
+- **비밀 회전 정책:** KIS appkey/secret, 텔레그램 토큰, DB 비밀번호의 주기적 회전 절차를 [docs/runbook.md](./runbook.md) 에 문서화.
+- **WBS 표기 정합성 거버넌스:** 본 문서에서 드러난 "완료 표기 vs 실측" 괴리 재발 방지를 위해, 각 WBS 완료 시 **검증 명령 출력 캡처를 증빙으로 첨부**하는 규칙을 강화([AGENTS.md](../AGENTS.md) 의 검증·증빙 강제 원칙 적용).
+
+---
+
+## 6. 검증 방법 (각 단계 실행 시)
+
+- **P0:** `git status` 산출물 미추적 확인, 시크릿 평문 grep 0건, 회전된 자격증명으로 정상 기동.
+- **Track A:** `cd src/dotnet && dotnet test` 로 패리티/단위/E2E 그린. 패리티 리포트 JSON 을 Python 출력과 diff. 운영 경로 Python 호출 0건.
+- **Track B:** `curl /health/ready` 200, 비인증 요청 401, `docker compose up` 기동, CI 테스트/커버리지 게이트 동작. Polly 재시도는 장애 주입 테스트로 검증.
