```

### Key Design Decisions (SOLID + Domain-Driven)

1. **Razor Pages (Server-Rendered)** — No WASM; Admin UI uses server-side rendering with cookie auth. Why? Simpler security, faster initial load, team familiarity.

2. **Repository Pattern + Dapper ORM** — SQL-first, no EF. Why? Direct control over queries, performance, audit trail (raw SQL = explicit intent).

3. **Read-Only KIS Governance** — `AssertReadOnly()` blocks all /trading/ paths + TTTC*/VTTC* TR_IDs. Why? Hard mandate: data collection only, no order placement.

4. **PostgreSQL Single Source of Truth** — All collection runs, snapshots, tokens centralized. Why? Audit, reproducibility, real-time coordination.

5. **Hybrid Python-to-.NET Transition** — Python handles legacy ops:data-collect; .NET does web, API, orchestration. Why? Gradual migration reduces risk; Python stays until .NET collection fully validated.

6. **Contract-Driven Validation** — Parity, Provenance, Scheduler, Normalization contracts in CI. Why? Catch schema drift, data quality regressions before deployment.

7. **Canonical JSON Renderer** (.NET Tools) — Single source of operational_report.json schema. Why? One contract, all tools emit to it (no format wars).

## Project Overview

**QuantEngine v0.1** — A comprehensive quantitative analysis and data collection system for retirement asset portfolio management.

- **Architecture**: .NET 9 + C# (web UI + APIs, primary); Python (legacy data collection, gradual deprecation)
- **Critical Path**: KIS API → PostgreSQL → Admin Dashboard (read-only quotations only, no trading APIs)
- **Validation**: 30+ contract validators + 9 parallel CI jobs + manual release gates
- **Web UI**: Blazor Interactive WebAssembly (MudBlazor) + ASP.NET Core Web API (API-First)
- **Database**: PostgreSQL (Npgsql 8.0), single unified database
- **Data Source**: KIS Open API (quotations/ranking read-only), with fallbacks
- **Key Runtimes**: .NET 9, Python 3.9+, Node.js 16+

## Deployment & Operations (Phase 4-5, 2026-07-11)

**Production Server**: Hetzner Cloud `178.104.200.7` (kjh2064@178.104.200.7)

Projects on server:
1. **TaxBaik** (홈페이지) — Nginx location `/taxbaik`
2. **QuantEngine** (데이터 수집/분석) — Nginx location `/quantengine`

### ⚠️ CRITICAL: CI/CD-Only Deployment Mandate

**Rule**: ALL production deployments MUST go through Gitea Actions CI/CD. Manual SSH deployments are **FORBIDDEN**.

**Why**: 
- Automatic validation (build, health checks, version verification)
- Audit trail (all deployments logged in Gitea Actions)
- Consistent process (no manual errors)
- Rollback safety (deployment history retained)
- Release traceability (version control via git tags)

### ⚠️ CRITICAL: DB Secret Management (Incident 2026-07-12)

**Incident**: `quant.taxbaik.com/login`이 `28P01 password authentication failed`로 장애 발생.
원인: `appsettings.Production.json`에 하드코딩되어 배포된 DB 비밀번호가, 실제 DB 비밀번호가
로테이션된 이후에도 계속 옛날 값(심지어 이전 세션에서 검증 없이 넣은 placeholder였던 적도 있음)
그대로 배포되고 있었음.

**Rule**: **DB 접속 문자열(`ConnectionStrings`)은 절대 `appsettings.Production.json`이나
워크플로우 파일에 하드코딩하지 않는다.** `prepare-release.yml`이 생성하는
`appsettings.Production.json`에는 `Logging` 설정만 있고 `ConnectionStrings`는 없다 —
이는 의도된 설계다 (Gitea Release는 누구나 다운로드 가능한 아티팩트이므로 시크릿을
담으면 안 됨).

**실제 DB 비밀번호의 출처**: 프로덕션 서버의 `/home/kjh2064/.config/quantengine.env`
파일 (`ConnectionStrings__DefaultConnection=...` 형식) 하나뿐이며,
`quantengine.service.d/env.conf` drop-in의 `EnvironmentFile=` 지시자로 systemd가
이 값을 환경변수로 주입한다. ASP.NET Core 설정 우선순위상 **환경변수가
`appsettings.Production.json`을 오버라이드**하므로, 배포되는 아티팩트 자체에는
DB 정보가 없어도 서비스는 정상 동작한다.

**DB 비밀번호가 바뀌면** (로테이션 등): `/home/kjh2064/.config/quantengine.env` 파일만
갱신하고 `sudo systemctl restart quantengine`. 워크플로우 파일이나 Gitea Secrets는
건드릴 필요 없음 (배포 파이프라인은 DB 비밀번호를 모른 채로 동작해야 정상).

**배포 전 체크리스트에 추가**:
- ✅ 새 릴리즈 배포 후 반드시 `/Account/Login` 실제 HTTP 응답 + `journalctl -u quantengine`에서
  `28P01`/`password authentication failed` 부재 확인 (단순 프로세스 `active` 상태만으로는
  DB 연결 실패를 못 잡음 — ASP.NET Core는 DB 없이도 기동은 되고 로그인 요청 시점에야 실패함)
- ✅ `.config/quantengine.env`의 존재와 `quantengine.service.d/env.conf`의
  `EnvironmentFile=` 배선이 서버에 유지되고 있는지 (systemd unit 자체를 재생성/덮어쓰는
  배포 방식으로 전환할 경우 이 drop-in이 날아가지 않는지 확인 필요)

### Production Deployment Strategy (Release-Based)

**Architecture**: Two-Workflow System (Release Creation → Deployment)

#### Workflow 1: prepare-release.yml (Release Creation)

**Purpose**: Create a release with built artifact

**Trigger**: Manual (`workflow_dispatch`)
```bash
# Visit Gitea Actions and select prepare-release.yml
# Input version: v0.1.20260711 (or any semantic version)
```

**What it does**:
1. ✓ Build (restore, build, publish)
2. ✓ Generate `appsettings.Production.json`
3. ✓ Package artifact: `.tar.gz`
4. ✓ Create git tag: `v0.1.20260711`
5. ✓ Create Gitea Release with artifact attached
6. ✓ Notify: Release ready for deployment

**Output**: Gitea Release with downloadable artifact

#### Workflow 2: deploy-prod.yml (Deployment)

**Purpose**: Deploy a release to production

**Trigger**: Manual (`workflow_dispatch`)
```bash
# Visit Gitea Actions and select deploy-prod.yml
# Input release: v0.1.20260711 (optional — uses latest if empty)
```

**What it does**:
1. ✓ Fetch Release (from Gitea Releases)
2. ✓ Download artifact
3. ✓ Verify SSH credentials
4. ✓ Upload to production server
5. ✓ Extract and symlink
6. ✓ Restart service
7. ✓ 6-point health checks
8. ✓ Report deployment status

**Deployment Pipeline (5 Stages)**:

| Stage | Purpose | Timeout |
|-------|---------|---------|
| 1. Fetch Release | Query Gitea Releases, download artifact | 10min |
| 2. Pre-Check | Verify SSH keys, secrets, release | 5min |
| 3. Deploy | Upload, extract, symlink, restart service | 30min |
| 4. Health Check | 6-point verification (HTTP, CSS, login, service, release, DB auth) | 10min |
| 5. Report | Final deployment status | Auto |

**Health Checks (Automatic)**:
- ✓ HTTP 200 on `/Account/Login`
- ✓ Login page content verification
- ✓ CSS file loads (`/css/admin.css`)
- ✓ Service status (systemctl active)
- ✓ Release verification (deployed release tag matches)
- ✓ **DB authentication check** (`journalctl`에서 `28P01`/`password authentication failed`
  부재 확인 — GET `/Account/Login`은 DB가 끊겨도 200을 반환하므로 이 체크가 없으면
  DB 장애를 배포 파이프라인이 놓친다. 2026-07-12 사고 이후 추가됨)

**Complete Deployment Flow**:
```
1. Code committed to main branch
2. Create release: prepare-release.yml workflow_dispatch (manual)
   → Builds code
   → Creates Gitea Release with artifact
   → Tags repository
3. Deploy release: deploy-prod.yml workflow_dispatch (manual)
   → Selects release version
   → Downloads artifact from Gitea Release
   → Deploys to production server
   → Runs health checks
   → Reports status
```

### Pre-Deployment Checklist

**Before creating a release**, verify:
1. ✅ Local build: `dotnet build src/dotnet/QuantEngine.Web/QuantEngine.Web.csproj -c Release` (0 errors, 0 warnings)
2. ✅ E2E tests pass: `npx playwright test`
3. ✅ Admin pages verified (200 status, no 500 errors)
4. ✅ All changes committed and pushed to main branch
5. ✅ No uncommitted changes: `git status`

### Release & Deployment Workflow

**Step 1: Create Release (prepare-release.yml)**
```bash
# Visit Gitea Actions
# https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions

# Run prepare-release.yml workflow
# Input: version = v0.1.20260711

# Workflow will:
# - Build and publish
# - Package artifact
# - Create git tag
# - Create Gitea Release
# - Attach artifact
```

**Step 2: Deploy Release (deploy-prod.yml)**
```bash
# Visit Gitea Actions (same page)
# Run deploy-prod.yml workflow
# Input: release = v0.1.20260711 (leave empty for latest)

# Workflow will:
# - Download artifact from release
# - Deploy to production server
# - Run health checks
# - Report status
```

### SSH Key Configuration (Required)

**Setup (One-time)**:
1. Generate ED25519 key locally (or reuse existing):
   ```bash
   ssh-keygen -t ed25519 -f ~/.ssh/quantengine_deploy -C "QuantEngine CI/CD"
   ```

2. Add public key to production server:
   ```bash
   ssh-copy-id -i ~/.ssh/quantengine_deploy.pub kjh2064@178.104.200.7
   ```

3. Get private key in base64 format:
   ```bash
   # macOS/Linux
   base64 -w 0 ~/.ssh/quantengine_deploy > /tmp/key_b64.txt
   cat /tmp/key_b64.txt | pbcopy
   
   # Or Windows PowerShell
   $key = Get-Content ~/.ssh/quantengine_deploy -Raw
   [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes($key)) | Set-Clipboard
   ```

4. Configure in Gitea:
   - URL: https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/settings/secrets
   - Add secret: `DEPLOY_SSH_KEY_B64` (base64-encoded private key)
   - Or: `DEPLOY_SSH_KEY` (raw PEM format)
   - Also add: `GITEA_TOKEN` (for release API access)
     - Generate at: https://gitea.taxbaik.com/user/settings/applications
     - Required permissions: `repo` + `read:actions`

### Deployment Monitoring

**During Deployment**:
- Watch live in Gitea Actions UI
- Jobs complete in order: Build → Pre-Check → Deploy → Health Check → Report

**After Deployment**:
```bash
# SSH into server
ssh kjh2064@178.104.200.7

# Check active deployment
readlink ~/quantengine_active

# View service status
systemctl status quantengine

# Tail live logs
journalctl -u quantengine -f

# Health check
curl -I http://127.0.0.1:5000/Account/Login
```

### Automatic Rollback (if health check fails)

If health check fails, deployment stops automatically:
1. Service restart may fail
2. Symlink update reverts to previous deployment
3. Gitea Actions marks deployment as FAILED
4. Logs include failure details

Manual rollback (if needed):
```bash
# List deployments
ls -lht ~/deployments/quantengine_*

# Revert symlink to previous version
ln -sfn /home/kjh2064/deployments/quantengine_YYYYMMDD_HHMMSS_COMMIT ~/quantengine_active

# Restart service
sudo systemctl restart quantengine

# Verify
curl http://127.0.0.1:5000/Account/Login
```

### Troubleshooting Deployment Failures

**Issue**: Build fails
- Check: `dotnet build` locally first
- Ensure: No compilation errors, 0 warnings

**Issue**: Health check timeout
- Check: Service logs: `journalctl -u quantengine -n 50`
- Check: Port 5000 listening: `ss -tlnp | grep 5000`
- Check: DB connectivity in appsettings.Production.json

**Issue**: SSH key error
- Verify: `DEPLOY_SSH_KEY_B64` or `DEPLOY_SSH_KEY` in Gitea Secrets
- Check: Public key added to `~/.ssh/authorized_keys` on server
- Test: `ssh -i ~/.ssh/key_file kjh2064@178.104.200.7 echo OK`

### Git Repository

**Gitea Server** (동일 호스트):
- **HTTP**: `https://gitea.taxbaik.com/kjh2064/QuantEngineByItz.git`
- **SSH**: `ssh://git@gitea.taxbaik.com:2222/kjh2064/QuantEngineByItz.git`

## UI Design Principles (2026-07-11 — Migrated to Razor Pages)

### Framework & Design System (NEW — 2026-07-11)

- **Primary Framework**: ASP.NET Core Razor Pages + Bootstrap 5 + Tabler UI
- **Design System**: Tabler (Bootstrap 5 기반), 밀집 레이아웃 + 전통 서버 렌더링
- **Render Mode**: **Server-side Razor Pages** — 모든 Admin UI는 서버에서 렌더링, Cookie 기반 인증 (API-First WASM 폐기)
- **Authentication**: Cookie Authentication (HttpOnly) + BCrypt password hashing + IP lockout (3 strikes, 15-min)
- **Deprecation**: **Blazor Interactive WebAssembly 폐기**, **MudBlazor 컴포넌트 폐기** (2026-07-11), **SmartAdmin 폐기**. 기존 WASM 코드는 `/QuantEngine.Web.Client` 폴더에 참고용으로만 보관 (`.sln`에서 제외)

### Component Development Rules (NEW)

1. **All Admin UI Development** (New + Refactored):
   - Use **Razor Pages** (.cshtml + .cshtml.cs PageModel) exclusively for admin
   - UI는 Repository/Service를 생성자 DI로 직접 호출 (API 홉 없음)
   - Bootstrap 5 + Tabler UI CSS classes for styling
   - **Form Validation**: DataAnnotations DTO + FluentValidation IValidator<T> 이중 검증
   - HTML `<form>` + tag helpers (`asp-for`, `asp-action`, `asp-page`)

2. **Authentication & Authorization**:
   - Cookie name: `QuantEngine.Admin.Auth` (HttpOnly, SameSite=Lax)
   - Session duration: 12 hours (sliding expiration)
   - Folder-level `[Authorize]` via `AuthorizeFolder("/Admin")` convention (per-page 반복 금지)
   - Login: `/Account/Login` (Razor Page, NO WASM)
   - Password: BCrypt-hashed (auto-migrates existing SHA-256 hashes on first login)
   - IP Lockout: 3 failed attempts → 15-minute lockout

3. **Data & Form Patterns**:
   - PageModel constructor: `public IndexModel(IWorkspaceRepository repo, ILogger<IndexModel> logger)`
   - Form submission: `OnPostAsync()` / `OnPostDeleteAsync()` (multi-handler pattern)
   - Validation failures: return `Page()` (re-render with ModelState errors)
   - Pagination: `PaginationModel` record (Page, TotalPages, Func<int,string> BuildPageUrl)
   - Empty states: `<PartialView name="_EmptyState" model="message" />`

4. **Component Mapping** (Bootstrap 5 + Tabler):

| UI Element | Component | Notes |
|-----------|-----------|-------|
| Button | `<button class="btn btn-primary">` | — |
| Input field | `<input asp-for="Property" class="form-control">` | tag helper |
| Dropdown | HTML `<select asp-for="Property">` | tag helper |
| Data grid | HTML `<table class="table">` | plain, no virtualization |
| Card | `<div class="card">` | Bootstrap card |
| Badge/Status | `<span class="badge bg-success">Active</span>` | Bootstrap badge |
| Layout container | `<div class="container-xl">` / `<div class="row">` | Bootstrap grid |
| Navigation | HTML navbar in `_AdminLayout.cshtml` | sidebar + topbar |
| Loading | N/A (server-rendered) | no loading states needed |
| Icons | Bootstrap Icons (`<i class="bi bi-*"></i>`) | CDN |
| Modal/Dialog | Bootstrap modal or inline `confirm()` | avoid unnecessary modals |
| Validation msg | `<span asp-validation-for="Property" class="d-block alert alert-danger mt-2">` | tag helper |

dotnet watch run --project QuantEngine.Web  # Hot-reload (http://localhost:5265)
dotnet run --project QuantEngine.Web        # Run API server
```

### Collection Pipeline Testing (Phase 2)
```powershell
# Set KIS credentials (sandbox account)
$env:KIS_APP_Key_TEST = "your_kis_test_key"
$env:KIS_APP_Secret_TEST = "your_kis_test_secret"

# Start web server (http://localhost:5265)
dotnet run --project QuantEngine.Web

# Verify Collection dashboard
# Navigate to http://localhost:5265/collection
# - Click "Start Collection" to trigger async run
# - Backend uses PostgreSQL-backed data storage
# - Dashboard updates with run status, snapshots, errors

# Verify API endpoints
curl http://localhost:5265/api/collection/state
curl http://localhost:5265/api/collection/runs
curl "http://localhost:5265/api/collection/latest/005930"
```

## API Endpoints (Phase 1 + 2)

### Workspace & History (Phase 1)
All endpoints prefixed with `/api/`:

| Route | Purpose |
|-------|---------|
| `GET /state` | Full UI state snapshot |
| `GET /tables` | Browsable tables list |
| `GET /table-rows` | Paginated rows |
| `POST /settings/save` | Save settings |
| `POST /account-snapshot/save` | Save snapshots |
| `POST /bootstrap` | Seed DB from JSON |
| `POST /account-snapshot/import-tsv` | Import TSV |
| `POST /autofix` | Auto-correct data |

### Collection Pipeline (Phase 2)
| Route | Purpose |
|-------|---------|
| `GET /collection/state` | Dashboard summary (runs, snapshots, errors) |
| `GET /collection/runs` | Recent collection runs (paginated) |
| `GET /collection/runs/{runId}/snapshots` | Snapshots from a run |
| `GET /collection/runs/{runId}/errors` | Errors from a run |
| `GET /collection/latest/{ticker}` | Latest snapshots for ticker |
| `POST /collection/run` | Start new collection run (async) |

### Collection Run Status Values
| Status | Meaning | UI Badge | Transitions |
|--------|---------|----------|------------|
| `running` | Collection in progress | <span class="badge bg-warning">진행 중</span> | → completed or failed |
| `completed` | Collection finished (may have errors) | <span class="badge bg-success">완료</span> | (final) |
| `failed` | Collection crashed/aborted | <span class="badge bg-danger">실패</span> | (final) |
| `pending` | Queued, not yet started | <span class="badge bg-secondary">대기 중</span> | → running |

### Collection Run Success Criteria
**Success** is defined as:
- Status = `completed` (not `failed`)
- `TotalSnapshots > 0` (at least one snapshot captured)
- `TotalErrors == 0` OR `TotalErrors < TotalSnapshots * 0.1` (error rate < 10%)

**Partial Success** (warning state):
- Status = `completed`
- `TotalSnapshots > 0` (some data captured)
- `TotalErrors > 0` (has errors, but not total loss)

**Failure**:
- Status = `failed` OR
- Status = `completed` + `TotalSnapshots == 0` (no data captured)

UI: `Pages/Admin/Collection/Index.cshtml` — status 값에 따라 배지 색상 결정, 향후 TotalSnapshots/TotalErrors로 상세 상태 표시

## KIS API Client Security (Phase 2)

### Governance Enforcement
- **Read-Only Mandate**: `AssertReadOnly(path, trId)` blocks all trading-related endpoints
- **Forbidden Paths**: `/trading/` substring triggers 🚫 immediate exception
- **Forbidden TR_IDs**: TTTC* / VTTC* prefixes (buy/sell order codes) blocked
- **Source**: `governance/rules/06_no_direct_api_trading.yaml`

### Token Management
- **ITokenCache** abstraction: PostgreSQL-backed in production
- **Credential Loading**:
  - Windows environment variables: `KIS_APP_Key`, `KIS_APP_Secret`, `KIS_APP_Key_TEST`, `KIS_APP_Secret_TEST`
  - Fallback: `HKCU\Environment` registry (Windows only)
  - Account modes: `"real"` (prod) vs `"mock"` (sandbox)

### Quotation Methods (All Read-Only)
1. **GetCurrentPriceAsync** (FHKST01010100) — Current price inquiry
2. **GetAskingPrice10LevelAsync** (FHKST01010200) — Order book (10-level)
3. **GetDailyShortSaleAsync** (FHPST04830000) — Short-sale trends
4. **GetDailyItemChartPriceAsync** (FHKST03010100) — Daily OHLCV data
5. **GetInvestorTrendAsync** (FHKST01010900) — Investor sentiment (개인/외국인/기관)

## Local Development & Testing (2026-07-11)

### ⚠️ CRITICAL: SSH Tunnel for Remote Database Access

**Never use Docker locally.** Always use SSH tunneling to connect to remote PostgreSQL:

```powershell
# 1. Setup SSH tunnel (Terminal 1) — forwards local 5432 to remote DB
ssh -L 127.0.0.1:5432:localhost:5432 kjh2064@178.104.200.7 -N

# 2. Configure appsettings.Development.json
{
  "ConnectionStrings": {
    "DefaultConnection": "Host=127.0.0.1;Database=quantenginedb;Username=quantengine_app;Password=quantengine_app;Search Path=quantengine;"
  }
}

# 3. Start service locally (Terminal 2)
cd src/dotnet
dotnet watch run --project QuantEngine.Web

# 4. Access locally
http://localhost:5265/Account/Login
```

### Mandatory Pre-Deployment Checklist

**EVERY code change must pass:**

1. ✅ **Local build (0 errors, 0 warnings)**
   ```powershell
   dotnet build src/dotnet/QuantEngine.Web/QuantEngine.Web.csproj -c Release
   ```

2. ✅ **Local service startup with SSH tunnel**
   - Service must start without DB connection errors
   - DbUp migrations must succeed

3. ✅ **Login test (admin/quant123!)**
   - `/Account/Login` must return 200
   - Authentication flow must complete
   - Cookie must be set

4. ✅ **All Admin pages must load**
   - `/Admin/Dashboard` → 200 (NOT 500)
   - `/Admin/Users` → 200 (NOT 500)
   - `/Admin/Collection` → 200 (NOT 500)
   - `/Admin/Monitoring` → 200 (NOT 500)
   - `/Admin/Operations` → 200 (NOT 500)
   - **No 500 errors in response body**

5. ✅ **Playwright E2E tests pass**
   ```powershell
   npx playwright test tests/e2e/complete-admin-flow.spec.ts
   ```

### Deployment Gates

**NEVER deploy without:**
- ❌ Local testing complete
- ❌ All Admin pages verified (200 status, no 500 errors)
- ❌ E2E tests passing
- ❌ Authorization Policy configured (if changes made to Program.cs)

**Deployment failure is better than service outage.** Halt and investigate if local tests fail.

### Gitea Actions Workflows

**Active Workflows**:
1. **prepare-release.yml** — Release creation (workflow_dispatch only)
   - Build → Publish → Package → Tag → Gitea Release
   - Does NOT write ConnectionStrings into the artifact (see "DB Secret
     Management" above) — only `Logging` config ships in `appsettings.Production.json`

2. **deploy-prod.yml** — Production deployment (workflow_dispatch only, takes a release tag)
   - 5 stages: Fetch Release → Pre-Check → Deploy → Health Check → Report
   - 6-point health checks (HTTP, login page, CSS, service, release, DB auth)
   - SSH-based deployment with artifact validation

3. **ci.yml** — PR validation (on:pull_request)
   - 29 validators for code quality
   - Runs on every pull request

**Accessing Gitea Actions**:
- Web UI: https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions
- Runs API: https://gitea.taxbaik.com/api/v1/repos/kjh2064/QuantEngineByItz/actions/runs

### API Monitoring (CLI)

Monitor deployment status from command line:

```powershell
# Setup (one-time)
$env:GITEA_TOKEN_TAXBAIK = "your_gitea_personal_token"

# List recent deployment runs
$token = $env:GITEA_TOKEN_TAXBAIK
$response = Invoke-WebRequest `
    -Uri "https://gitea.taxbaik.com/api/v1/repos/kjh2064/QuantEngineByItz/actions/runs?limit=5" `
    -Headers @{ "Authorization" = "token $token" }
($response.Content | ConvertFrom-Json).workflow_runs | ForEach-Object {
    Write-Host "Run #$($_.id): $($_.display_title) [$($_.conclusion)]"
}

# Get specific run details
$run_id = 1234  # Replace with actual run ID
$response = Invoke-WebRequest `
    -Uri "https://gitea.taxbaik.com/api/v1/repos/kjh2064/QuantEngineByItz/actions/runs/$run_id" `
    -Headers @{ "Authorization" = "token $token" }
$run = $response.Content | ConvertFrom-Json
Write-Host "Commit: $($run.head_sha)"
Write-Host "Status: $($run.status) / $($run.conclusion)"
```

See `docs/GITEA_ACTIONS_API_GUIDE.md` for complete API reference.

### Deployment Secrets Configuration

**Required Secrets** (Gitea Repository Settings → Secrets):

| Secret | Type | Purpose |
|--------|------|---------|
| `DEPLOY_SSH_KEY_B64` | Base64 (recommended) | ED25519 private key for SSH |
| `DEPLOY_SSH_KEY` | PEM (alternative) | Raw private key format |
| `DEPLOY_HOST` | Text | Production server IP (178.104.200.7) |
| `DEPLOY_USER` | Text | SSH username (kjh2064) |

**How to add secrets**:
1. Go to: https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/settings/secrets
2. Click "Add Secret"
3. Name: `DEPLOY_SSH_KEY_B64`
4. Value: `base64 -w 0 ~/.ssh/deploy_key | pbcopy` (macOS) or `certutil -encode deploy_key deploy_key.b64` (Windows)
5. Save

## Core Workflows & Common Scenarios

### Scenario 1: Day-to-Day Development (Code Change)

1. **Make code changes** (C# Razor Pages / .NET API / Python tools)
2. **Local validation**:
   ```powershell
   dotnet build src/dotnet/QuantEngine.Web/QuantEngine.Web.csproj -c Release
   dotnet test src/dotnet/QuantEngine.Core.Tests -c Release
   ```
3. **Test admin pages locally** (with SSH tunnel):
   ```powershell
   ssh -L 127.0.0.1:5432:localhost:5432 kjh2064@178.104.200.7 -N &
   dotnet watch run --project QuantEngine.Web
   # Verify: /Admin/Dashboard, /Admin/Users, /Admin/Collection, etc. all return 200
   ```
4. **Commit & push**: Changes automatically trigger ci.yml
   - Core validators run first (blocking others)
   - Parallel validators (contracts, UI, DB, calibration) run independently
   - notify-results summarizes all 9 jobs in PR comment
   - Expected CI time: ~15-20min (was ~40min before 2026-07-24 refactor)

### Scenario 2: Data Collection Setup (KIS API Validation)

1. **Obtain KIS credentials** (real or mock account)
2. **Validate with mock account**:
   ```powershell
   $env:KIS_APP_Key_TEST="<test_key>"
   $env:KIS_APP_Secret_TEST="<test_secret>"
   python tools/validate_kis_api_credentials_v1.py --account mock --ticker 005930 --dry-run
   ```
3. **Run real collection** (if approved):
   ```powershell
   $env:KIS_APP_Key="<real_key>"
   $env:KIS_APP_Secret="<real_secret>"
   python tools/run_kis_data_collection_v1.py --input-json GatherTradingData.json --sqlite-db src/quant_engine/kis_data_collection.db --output-json Temp/kis_data_collection_v1.json --kis-account real
   ```
4. **Verify database**:
   ```sql
   SELECT COUNT(*) FROM kis_collection_runs;
   SELECT COUNT(*) FROM kis_collection_snapshots;
   ```

### Scenario 3: Admin Data Editing (Snapshot Admin Web UI)

1. **Start snapshot admin server**:
   ```powershell
   python tools/run_snapshot_admin_server_v1.py --host 127.0.0.1 --port 8787 --db src/quant_engine/snapshot_admin.db --seed GatherTradingData.json
   ```
2. **Access web UI**: http://127.0.0.1:8787
3. **Edit settings / account_snapshot** in browser (like Excel)
4. **Manage changes**: Approval & Locks area handles change history, undo, approval workflow
5. **Export for CI**: `/api/export` → JSON or "Export approval packet" button

### Scenario 4: Release & Deployment (Multi-Stage)

**Stage 1: Local validation**
```powershell
npm run ops:validate              # Warn-only (allow some issues)
npm run full-gate                 # Strict (all gates PASS)
```

**Stage 2: Create release** (manual via Gitea Actions)
```
→ Visit https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions
→ Run "prepare-release.yml" workflow_dispatch
  - Builds and publishes .NET
  - Creates git tag (e.g., quant_20260724.0.abc1234)
  - Generates Gitea Release with artifact + checksums
  - Packages as .tar.gz
```

**Stage 3: Deploy** (manual, only after release exists)
```
→ Run "deploy-prod.yml" workflow_dispatch
  - Downloads release artifact from Gitea
  - Validates checksums and manifest
  - Verifies upstream CI success
  - SSH uploads to production server (178.104.200.7)
  - Extracts and symlinks
  - Restarts systemd service
  - 6-point health checks (HTTP, login page, CSS, service, release tag, DB auth)
  - Reports final status
```

**Pre-deployment checklist** (MANDATORY):
- ✅ Local build: 0 errors, 0 warnings
- ✅ E2E tests pass: `npx playwright test`
- ✅ All admin pages tested locally (200 status, no 500)
- ✅ `git status` clean (no uncommitted changes)
- ✅ Commit pushed to main

### Scenario 5: CI Workflow Debugging

**Problem**: A specific validation fails in CI
1. Identify failing job from PR comment (notify-results output)
2. Reproduce locally:
   ```powershell
   # For core, wbs-audit, dotnet-contracts: run relevant Python validators
   python tools/validate_dotnet_migration_execution_plan_v1.py
   python tools/validate_dotnet_parity_contract_v1.py
   # etc.
   ```
3. Fix and re-push (triggers ci.yml again)
4. Monitor in Gitea Actions dashboard

**Problem**: Workflow syntax error
1. Validate locally:
   ```powershell
   python tools/validate_gitea_ci_workflow_lint_v1.py --workflow .gitea/workflows/ci.yml
   ```
2. Fix YAML and test again

### Scenario 6: Database Schema Changes

1. **Create migration**: `src/dotnet/QuantEngine.Infrastructure/Migrations/V003.sql`
2. **Update DBML**: `docs/db/quantengine.dbml` (same commit)
   - DbUp auto-applies migrations on startup
   - DBML is reference documentation
3. **Test locally** (with SSH tunnel): Migrations must apply cleanly
4. **Commit both** (SQL + DBML) together
5. **CI validates**: ci.yml applies migrations to test PostgreSQL service

### When Things Break

| Issue | Root Cause | Fix |
|-------|-----------|-----|
| Admin page returns 500 | Likely unhandled DB exception or auth issue | Check journalctl, verify ConnectionStrings in production env |
| KIS API fails with "not found" | Ticker doesn't exist in KIS | Use fallback (Naver → Yahoo → OpenDART) |
| Snapshot admin won't load | SQLite DB corrupted or missing | Delete and re-seed from GatherTradingData.json |
| CI takes >25min | core job is slow or parallel jobs stalling | Profile individual job logs; likely DB migrations or large test suite |
| Deployment health check fails (DB 28P01) | DB password rotated but not updated in production env | Update `/home/kjh2064/.config/quantengine.env` on server only (not in repo) |

---

## Notes for Contributors (2026-07-11 — Updated 2026-07-24)

### Code Standards

- **SQL Safety**: Whitelist-only table access (enum switch in Repository). Never raw concatenation.
- **KIS API**: Read-only quotations/ranking; no order/trade endpoints. Enforced via `AssertReadOnly()` in client.
- **Admin UI**: Server-rendered Razor Pages only; no WASM. PageModel constructor: DI repos directly, no API hops.
- **Authentication**: Cookie-based (HttpOnly, SameSite=Lax). No Bearer tokens. Password reset via API endpoints only (no UI form).
- **Password Hashing**: BCrypt (auto-migrates from SHA-256 on login). IP lockout: 3 failed attempts → 15 min ban.
- **Database**: PostgreSQL as single source of truth. Dapper ORM + raw SQL (no Entity Framework). Auto-migrations via DbUp.
- **Error Handling**: Validate only at system boundaries (user input, external APIs). Trust internal guarantees.
- **Comments**: Minimal; only explain WHY for non-obvious constraints. Removed comments on refactor; code names explain WHAT.

### Repository Structure Rules

- **Legacy Code**: `QuantEngine.Web.Client` (WASM) kept for reference; excluded from .sln, not built.
- **DBML Sync (2026-07-12)**: All DbUp migrations (`V*.sql`) must sync with `docs/db/quantengine.dbml` in same commit. Future schema reads use DBML.
- **Diagrams**: Mermaid diagrams in `docs/diagrams/` for state machines, flows, sequences (e.g., collection-pipeline.md).
- **WBS Evidence (2026-07-12)**: Task completion = `npm run verify:task -- <TASK_ID>` PASS (BE=DB queries/logs/JSON, FE=Playwright+screenshot). Full check: `npm run verify:wbs`.

### Testing & Validation

- **Local pre-deployment**: Build (0 errors), E2E tests, all admin pages return 200 (no 500), git status clean.
- **CI auto-validation**: 9 parallel jobs (core + 8 independent). Expected time: ~15-20min (was ~40min, parallelized 2026-07-24).
  - core: CRITICAL tests + DB setup
  - wbs-audit, dotnet-contracts, ui-storage, database-schema, calibration, operational-reporting, security-validation, workflow-lint: parallel
  - notify-results: final PR summary
- **Release gates**: `npm run ops:validate` (warn-ok), `npm run full-gate` (strict), `npm run ops:release` (warn-ok + full DAG).

### Deployment

- **Mandatory checklist**: Local build, E2E pass, admin pages 200, git clean, pushed to main.
- **Release creation**: Manual workflow_dispatch → prepare-release.yml (tag + artifact).
- **Deployment**: Manual workflow_dispatch → deploy-prod.yml (SSH upload + health checks).
- **DB secrets**: Never hardcode `ConnectionStrings` in artifacts. Runtime injection via systemd EnvironmentFile (production only).
- **Health checks (6-point)**: HTTP 200, login page, CSS load, service active, release tag match, DB auth (no 28P01 errors).

### Known Issues & Tech Debt

- **Newtonsoft.Json**: High-severity vuln (GHSA-5crp-9r3c-p9vr); update or replace when feasible.
- **Python-to-.NET transition**: Legacy `ops:data-collect` remains until .NET collection validated in production (est. Q3 2026).
- **Gitea Actions limitation**: Act runner ↔ Gitea network issues (workaround: manual SSH deployment active).

### Reliability & Data Quality

- **Reproducibility**: All validation gates, WBS tasks, and CI runs must be reproducible. Use deterministic inputs (GatherTradingData.json seed).
- **Audit trail**: PostgreSQL is source of truth for all collection runs/snapshots. Raw SQL = explicit intent (no ORM magic).
- **Contract validation**: Parity, Provenance, Scheduler, Normalization contracts catch schema drift before deployment.
- **Canonical rendering**: .NET Tools (QuantEngine.Tools) is single source for operational_report.json schema. No format divergence.

### When Making Changes

1. **Change type determines scope**:
   - Bug fix: No cleanup beyond fix itself.
   - Feature: Add only what's requested; no hypothetical abstractions.
   - Refactor: Break down large methods/classes; extract reusable patterns only if used 3+ times.
   - Architecture change: Must update CLAUDE.md and CI contracts simultaneously.

2. **Locality-first**: Prefer editing in place. Create new files only when genuinely new concept or isolation needed.

3. **Testing locality**: Unit tests verify code correctness; UI testing (Playwright) verifies feature correctness. If UI can't be tested, say so.

4. **Git commits**: New commits preferred over amend. Include co-author: `Claude Haiku 4.5 <noreply@anthropic.com>`.

## Gitea Actions Workflow Structure (2026-07-24)

### Workflow Architecture Refactoring

**2026-07-24 refactoring**: Single-job ci.yml (30+ steps, ~40min runtime) → **9-job parallel pipeline** (~15-20min runtime).

### CI Pipeline Jobs (ci.yml)

| Job | Dependencies | Purpose | Parallelizable |
|-----|--------------|---------|---|
| **core** | — | CRITICAL: .NET tests, API trading gate, KIS creds, DB migrations | ✗ (blocks others) |
| **wbs-audit** | core | WBS validation, platform migration, coverage audits | ✓ |
| **dotnet-contracts** | core | .NET parity, provenance, scheduler, normalization contracts | ✓ |
| **ui-storage** | — | Admin UI, storage backend, integration tests | ✓ |
| **database-schema** | — | DB pipeline, PostgreSQL schema, history contracts | ✓ |
| **calibration-pipeline** | core | Calibration priority, change ledger, qualitative sell strategy | ✓ |
| **operational-reporting** | calibration | Decision packet, operational report, performance metrics | ✗ (depends on calibration) |
| **security-validation** | — | Secrets contract, workflow validation | ✓ |
| **workflow-lint** | — | CI workflow structure, secrets contract | ✓ |
| **notify-results** | ALL | PR notification with job status summary | — |

**Dependency Graph**:
```
core ─┬─> wbs-audit ─────────────────────┐
      ├─> dotnet-contracts ─────────────┤
      └─> calibration-pipeline ────────┤
              └─> operational-reporting ─┤
                                         └─> notify-results
ui-storage ────────────────────────────────┘
database-schema ──────────────────────────┘
security-validation ───────────────────────┘
workflow-lint ─────────────────────────────┘
```

### Other Workflow Files

| File | Trigger | Purpose | Status |
|------|---------|---------|--------|
| **kis_data_collection.yml** | cron (00:30 KST M-F) + dispatch | Validate KIS credentials & PostgreSQL pipeline | ✓ 2026-07-24 |
| **qualitative_sell_strategy.yml** | cron (00:15 KST M-F) + push + dispatch | Validate sell strategy pipeline & store | ✓ 2026-07-24 |
| **workflow_lint.yml** (was ci_lint.yml) | push (.gitea/workflows/) + dispatch | Lint all workflow files, validate job dependencies, secrets contract | ✓ 2026-07-24 |
| **snapshot_admin.yml** | push (snapshot_admin_*) + dispatch | Validate snapshot admin workflow & UI (2 jobs) | ✓ 2026-07-24 |
| **prepare-release.yml** | workflow_run (ci.yml success) + dispatch | Build, tag, create Gitea Release with artifact + checksums | — |
| **deploy-prod.yml** | dispatch | Deploy release, run health checks, report status (3 jobs) | — |

### Performance Improvements (2026-07-24)

**ci.yml refactoring results**:
- **Before**: 1 job, 30+ sequential steps, ~40min runtime
- **After**: 9 jobs, 7 in parallel, ~15-20min total runtime
- **Speedup**: ~2-2.5x faster CI feedback (core branch blocks only downstream, others parallel)
- **Fault isolation**: Single validation failure no longer blocks unrelated checks

**Key changes**:
1. **Setup consolidation**: Database migrations, Python, .NET setup in `core` job only
2. **Parallel validation groups**: 7 jobs run independently from core (ui-storage, database-schema, security-validation, workflow-lint, etc.)
3. **Dependency clarity**: `needs:` explicitly defines blocking relationships
4. **Error reporting**: `notify-results` summarizes all 9 job statuses in PR comment

### Workflow Maintenance Checklist

When modifying workflows (.gitea/workflows/*.yml):

1. ✅ Update `workflow_lint.yml` if adding new triggers or job dependencies
2. ✅ Test locally with `python3 tools/validate_gitea_ci_workflow_lint_v1.py`
3. ✅ Verify all `needs:` references point to existing jobs
4. ✅ Document new jobs in this section above
5. ✅ Validate YAML syntax: `python3 -m yaml < .gitea/workflows/new.yml`
6. ✅ Ensure no hardcoded secrets in workflow files (env vars only)

### Troubleshooting Workflows

**Symptom**: CI job timeout
- **Check**: Does your job need PostgreSQL? Only `core` provides it; others must be independent.
- **Fix**: Add `services: postgres:` block or restructure to parallel-safe job.

**Symptom**: Cascading failure (multiple jobs fail)
- **Check**: Does your job have missing dependencies? Review `needs:` and dependency graph above.
- **Fix**: Add explicit `needs: [job_name]` if job depends on another's output.

**Symptom**: "job not found" error in notify-results
- **Check**: Job name typo in `notify-results.needs` list.
- **Fix**: Match job name exactly (case-sensitive).

## Workflow Trigger Schedule (2026-07-24)

| Time (KST) | Workflow | Trigger | Purpose |
|-----------|----------|---------|---------|
| 00:15 | qualitative_sell_strategy.yml | cron (M-F) | Validate sell strategy before daily operations |
| 00:30 | kis_data_collection.yml | cron (M-F) | Validate KIS API & DB pipeline before data collection |
| Push | ci.yml | on:push (main) | Validate code on every push to main |
| PR | ci.yml | on:pull_request | Gate PR merges with full validation suite |
| Manual | prepare-release.yml | workflow_dispatch | Create release tag & artifact |
| Manual | deploy-prod.yml | workflow_dispatch | Deploy release to production |

**Dependencies**: 
- Release creation (prepare-release.yml) is gated by ci.yml success (workflow_run trigger)
- Deployment (deploy-prod.yml) is manual — only after release artifact exists

## OMS·WMS·ERP Commercialization Project: Strategic Execution Framework (2026-07-26)

**OFFICIAL PROJECT FOUNDATION** — 30-Year Senior Architect/PM/PL/Dev/UX/QA/User Perspective

**⚠️ CORRECTION (2026-07-26)**: Initial WBS was fabricated from filenames + general knowledge without reading PDFs. Post-advisor review, now **based on actual PDF specifications** (5 documents, 179 pages). All numbers, team size, budget, timelines in previous version marked DRAFT. See section below for ground-truth framework.

### Strategic Vision

**Objective**: Enterprise-grade Order Management (OMS) + Warehouse Management (WMS) + Enterprise Resource Planning (ERP) platform commercialization with:
- 4-layer input components (Primitive/Composite/Smart/Domain Templates)
- 11 standard CRUD templates (fully normalized data model)
- Vue 3 + TypeScript modern stack
- SOLID principles, data consistency, process simplification
- 100% test-driven, zero hallucination, full traceability

**Duration**: 18 weeks (4.5 months, 12 phases)  
**Team**: 13 FTE (PM, PL, 4 FE devs, 1 UX, 2 QA, 1 DevOps, 0.5 security, 0.5 docs)  
**Budget**: $371K USD (infrastructure, tooling, salaries)  
**Target Launch**: Q4 2026

### 30 Strategic Principles (With Execution Framework)

**Complete framework**: 📄 [`spec/61_strategic_execution_framework.yaml`](spec/61_strategic_execution_framework.yaml) (7,000+ lines)

**30 Principles Applied**:

| # | Principle | PDF Source | Success Metric |

| 1 | SOLID (SRP, OCP, LSP, ISP, DIP) | Architecture spec | No circular imports, domain independent |
| 2 | Code Refactoring (Continuous) | "bloated monoliths" warning | Component <300 lines, dependencies <5 |
| 3 | Data Consistency (SSOT) | "화면과 서버 데이터 해석 다르지 않게" | API DTO ≠ Screen Model ≠ Domain Model |
| 4 | Parsimony (No Gold-Plating) | Template spec precise | Feature = PDF requirement + P0/P1 tag |
| 5 | Normalization (3NF minimum) | Schema design | No repeating groups, full normalization |
| 6 | Denormalization (Justified) | Performance-only | <100ms proof required, TTL strategy |
| 7 | Process Simplification | Validate before automate | Workflow reviewed by domain experts |
| 8 | Patterns & Design | Reusable business transactions | 3+ usage → abstract into pattern |
| 9 | Standardization (Conventions) | Consistent naming, API contracts | ESLint rules, OpenAPI validation |
| 10 | Structuring (Layered) | 7-layer architecture spec | No higher → lower layer imports |
| 11 | Vibes Coding (Cognitive Load) | Clear naming, minimal overhead | Readable without docs, PR comment pass |
| 12 | Hallucination Prevention | Test-driven, ground truth | Every feature sourced, not assumed |
| 13 | Ground Truth & Reproducibility | Deterministic inputs, traceable | Seed data versioned, audit log exported |
