+# Roo 작업 시작 가이드
+
+## 작업 시작 시 필수 절차
+
+1. **`CLAUDE.md` 파일 반드시 읽기**
+   - 프로젝트 루트의 `CLAUDE.md` 파일을 먼저 읽어서 이전 작업 이력 확인
+   - 완료된 작업, 현재 진행 중인 작업, 알려진 문제점 파악
+   - 최근 작업 내용을 바탕으로 현재 작업과 충돌하지 않도록 주의
+
+2. **todo 목록 생성**
+   - 복잡한 작업은 반드시 `update_todo_list` 도구로 todo 목록 생성
+   - 각 단계별로 명확한 목표 설정
+
+3. **파일 수정 시 주의**
+   - `apply_diff` 도구는 정확한 검색/교체 블록 사용
+   - `read_file` 도구로 정확한 내용 확인 후 수정

+
+### 작업 분할 원칙
+1. 모든 새로운 작업을 시작하기 전 todo list 생성 (`update_todo_list` 도구 사용)
+2. 단일 항목 작업 중 컨텍스트 캐시 70% 초과 시:
+   - 현재 작업 상태를 하위작업에게 명확히 전달
+   - 하위작업에서 이어받아 작업 진행
+   - 완료 후 상위 작업에 결과 보고
+3. 하위작업은 `new_task` 도구로 생성하고 mode은 현재 모드 유지 또는 적절히 선택

+# 이력 조회 상태 표시기 구현
+
+## 개요
+이력 조회 페이지의 '▼ 옵션 불러오기' 버튼 오른쪽에 상태 표시기를 추가하여, 태그 목록 조회 상태를 시각적으로 표시합니다.
+
+## 구현 내용
+
+### 1. HTML 구조 ([`index.html`](src/Web/wwwroot/index.html:503))
+```html
+<div class="fg">
+  <div style="display:flex;align-items:center;gap:8px;flex-wrap:wrap">
+    <span>태그 선택 <em>(최대 8개, OR 조건)</em></span>
+    <button class="btn-b btn-sm" onclick="histLoad()">▼ 옵션 불러오기</button>
+    <span id="hist-load-status" class="hist-status">대기 중</span>
+  </div>
+  <div class="pb-name-grid">
+    <!-- select 8개 -->
+  </div>
+</div>
+```
+
+### 2. CSS 스타일 ([`style.css`](src/Web/wwwroot/css/style.css:815))
+- `.hist-status`: 상태 표시기 컨테이너
+- `.hist-status.loading`: 조회 중 (파란색)
+- `.hist-status.success`: 조회 완료 (초록색)
+- `.hist-status.error`: 조회 실패 (빨간색)
+- 성능 최적화: `contain: layout style`, `transform: translateZ(0)`
+
+### 3. JavaScript 로직 ([`app.js`](src/Web/wwwroot/js/app.js:688))
+- `histUpdateStatus(state, message)`: 상태 표시기 업데이트
+- `histLoad()`: 태그 목록 조회 및 상태 업데이트
+  - 조회 시작: `⏳ 조회 중...`
+  - 조회 완료: `✅ 조회 완료 (개수, 초)`
+  - 데이터 없음: `❌ 조회 데이터 없음 (0개)`
+  - 오류: `❌ 조회 실패: 메시지`
+
+## 수정된 문제들
+1. 초기 상태 "준비됨" → "대기 중"으로 변경
+2. 레이아웃 구조 개선 (flex 컨테이너 사용)
+3. CSS 애니메이션 제거 및 성능 최적화
+4. `requestAnimationFrame`으로 DOM 업데이트 지연
+
+## 남은 문제 (추가 작업 필요)
+- 태그 선택 시 페이지 hang 현상 원인 파악 필요
+  - `pb-name-grid`의 CSS grid 레이아웃과 select 요소 8개의 상호작용
+  - 브라우저 호환성 문제 가능성
+  - 메모리 누락 가능성
+
+## 테스트 방법
+1. 이력 조회 탭 진입 → "대기 중" 표시 확인
+2. '▼ 옵션 불러오기' 클릭 → 상태 변화 확인
+3. 태그 선택 시 페이지 반응성 확인

+# Text-to-SQL (PostgreSQL + TimeScaleDB) 추가 계획
+
+## 1. 개요
+
+ExperionCrawler 프로젝트에 **TimeScaleDB 하이퍼테이블**을 적용하여 시계열 데이터(`realtime_table`, `history_table`)의 성능과 확장성을 대폭 개선합니다. 또한 **Text-to-SQL 기능**을 추가하여 API를 통해 자연어/쿼리 입력으로 시계열 데이터를 조회·분석할 수 있도록 합니다.
+

+
+## 2. 현재 아키텍처 분석

+
+## 4. 구현 단계별 계획
+
+### 단계 1: TimeScaleDB 패키지 추가 및 초기화
+
+**목표**: TimeScaleDB 확장 활성화 및 하이퍼테이블 생성
+
+#### 4.1.1 NuGet 패키지 추가
+- `Npgsql.EntityFrameworkCore.PostgreSQL` (이미 존재)
+- `Npgsql.TimeScaleDB` (새로 추가)
+
+#### 4.1.2 데이터베이스 초기화 수정
+- [`ExperionDbContext`](src/Infrastructure/Database/ExperionDbContext.cs:1)에 TimeScaleDB 확장 활성화 코드 추가
+- `history_table` → `history_hypertable` (하이퍼테이블)로 마이그레이션
+- `realtime_table` → `realtime_hypertable` (하이퍼테이블)로 마이그레이션
+
+#### 4.1.3 마이그레이션 스크립트
+```sql
+-- TimeScaleDB 확장 활성화
+CREATE EXTENSION IF NOT EXISTS timescaledb;
+
+-- 기존 history_table 데이터를 백업
+CREATE TABLE history_table_backup AS SELECT * FROM history_table;
+
+-- 기존 테이블 삭제 후 하이퍼테이블 생성
+DROP TABLE history_table;
+SELECT create_hypertable('history_hypertable', 'recorded_at',
+    chunk_time_interval => INTERVAL '1 day',
+    create_default_indexes => true);
+
+-- 데이터 복원
+INSERT INTO history_hypertable (id, tagname, node_id, value, recorded_at)
+    SELECT id, tagname, node_id, value, recorded_at FROM history_table_backup;
+DROP TABLE history_table_backup;
+```
+
+---
+
+### 단계 2: Text-to-SQL 서비스 구현
+
+**목표**: 자연어/쿼리 입력으로 시계열 데이터를 조회하는 서비스 계층 구현
+
+#### 4.2.1 인터페이스 정의 (`ITextToSqlService`)
+```
+namespace ExperionCrawler.Core.Application.Interfaces;
+
+public interface ITextToSqlService
+{
+    /// <summary>자연어 질의를 SQL로 변환</summary>
+    Task<string> ParseNaturalLanguageAsync(string input);
+    
+    /// <summary>SQL 쿼리 실행 및 결과 반환</summary>
+    Task<SqlQueryResult> ExecuteQueryAsync(string sql);
+    
+    /// <summary>쿼리 제안 (자동 완성)</summary>
+    Task<IEnumerable<string>> SuggestQueriesAsync(string partialInput);
+    
+    /// <summary>시계열 분석 (평균, 최대, 최소, 추세)</summary>
+    Task<TimeSeriesAnalysisResult> AnalyzeAsync(string tagName, DateTime? from, DateTime? to);
+}
+```
+
+#### 4.2.2 구현체 (`TextToSqlService`)
+- **자연어 파싱**: 키워드 기반 파서 (tag name, 시간 범위, 집계 함수)
+- **SQL 생성**: TimeScaleDB 함수 (`time_bucket`, `avg`, `max`, `min`, `last`) 활용
+- **결과 매핑**: 동적 SQL → DTO 매핑
+
+#### 4.2.3 자연어 파싱 예시
+| 입력 | 생성된 SQL |
+|------|-----------|
+| "PV001 온도 최근 1시간 평균" | `SELECT time_bucket('5 min', recorded_at) AS bucket, AVG(value::float) FROM history_hypertable WHERE tagname = 'PV001' AND recorded_at > NOW() - INTERVAL '1 hour' GROUP BY bucket ORDER BY bucket` |
+| "전체 태그 현재 값" | `SELECT DISTINCT ON (tagname) tagname, livevalue, timestamp FROM realtime_hypertable ORDER BY tagname, timestamp DESC` |
+| "PV001, PV002 최근 24시간 최대값" | `SELECT time_bucket('1 hour', recorded_at) AS bucket, tagname, MAX(value::float) FROM history_hypertable WHERE tagname IN ('PV001', 'PV002') AND recorded_at > NOW() - INTERVAL '24 hour' GROUP BY bucket, tagname ORDER BY bucket, tagname` |
+
+---
+
+### 단계 3: API 엔드포인트 추가
+
+**목표**: Text-to-SQL 기능을 REST API로 노출
+
+#### 4.3.1 컨트롤러 (`TextToSqlController`)
+```
+[ApiController]
+[Route("api/text-to-sql")]
+public class TextToSqlController : ControllerBase
+{
+    private readonly ITextToSqlService _service;
+    
+    [HttpPost("parse")]
+    public Task<IActionResult> Parse([FromBody] NaturalLanguageQueryDto dto);
+    
+    [HttpPost("execute")]
+    public Task<IActionResult> Execute([FromBody] SqlQueryDto dto);
+    
+    [HttpGet("suggest")]
+    public Task<IActionResult> Suggest([FromQuery] string input);
+    
+    [HttpPost("analyze")]
+    public Task<IActionResult> Analyze([FromBody] AnalysisRequestDto dto);
+}
+```
+
+#### 4.3.2 DTO 정의
+```
+public class NaturalLanguageQueryDto
+{
+    public string Query { get; set; } = string.Empty;
+    public string Language { get; set; } = "ko"; // "ko" or "en"
+}
+
+public class SqlQueryDto
+{
+    public string Sql { get; set; } = string.Empty;
+    public int? Limit { get; set; } = 1000;
+}
+
+public class AnalysisRequestDto
+{
+    public List<string> TagNames { get; set; } = new();
+    public DateTime? From { get; set; }
+    public DateTime? To { get; set; }
+    public string Interval { get; set; } = "5 min"; // time_bucket interval
+}
+```
+
+---
+
+### 단계 4: TimeSeries 서비스 개선
+
+**목표**: TimeScaleDB 특화 함수 활용하여 성능 최적화
+
+#### 4.4.1 기존 `ExperionDbService` 수정
+- `history_table` → `history_hypertable` 참조로 변경
+- `realtime_table` → `realtime_hypertable` 참조로 변경
+- TimeScaleDB 함수 (`time_bucket`, `continuous aggregates`) 활용
+
+#### 4.4.2 연속 집계 (Continuous Aggregates) 생성
+```sql
+-- 5분 단위 집계 뷰 생성
+CREATE MATERIALIZED VIEW history_5min_agg
+WITH (timescaledb.continuous) AS
+SELECT
+    time_bucket('5 min', recorded_at) AS bucket,
+    tagname,
+    AVG(value::float) AS avg_value,
+    MIN(value::float) AS min_value,
+    MAX(value::float) AS max_value,
+    FIRST(value::float, recorded_at) AS open_value,
+    LAST(value::float, recorded_at) AS close_value,
+    COUNT(*) AS point_count
+FROM history_hypertable
+GROUP BY bucket, tagname;
+
+-- 기존 데이터 리프레시
+REFRESH MATERIALIZED VIEW history_5min_agg;
+```
+
+---
+
+### 단계 5: Program.cs 설정 업데이트
+
+**목표**: 서비스 등록 및 초기화 플로우 수정
+
+#### 4.5.1 서비스 등록
+```csharp
+// Text-to-SQL 서비스
+builder.Services.AddScoped<ITextToSqlService, TextToSqlService>();
+
+// TimeSeries 서비스
+builder.Services.AddScoped<ITimeSeriesService, TimeSeriesService>();
+```
+
+#### 4.5.2 연결 문자열 확인
+```json
+{
+  "ConnectionStrings": {
+    "DefaultConnection": "Host=localhost;Port=5432;Database=experion_crawler;Username=postgres;Password=postgres"
+  }
+}
+```
+

+| `realtime_hypertable` | 1시간 | 실시간 데이터는 1시간 단위 청크 |
+
+### 6.2 데이터 보존 정책
+```sql

+
+## 9. 예상 효과
+
+| 항목 | 기존 | 개선 후 |
+|------|------|--------|
+| 시계열 데이터 삽입 속도 | 일반 테이블 | TimeScaleDB 청킹으로 10x 이상 향상 |
+| 시간 범위 쿼리 | 전체 테이블 스캔 | 청크 제거로 빠른 응답 |
+| 데이터 압축 | 없음 | 자동 압축 (5-10x 저장공간 절약) |
+| 자동 보존 | 수동 삭제 | 정책 기반 자동 삭제 |
+| Text-to-SQL | 없음 | 자연어 기반 시계열 쿼리 |
+
+---
+
+## 10. 주의사항
+
+1. **TimeScaleDB 설치 prerequisite**: 대상 서버에 TimeScaleDB가 설치되어 있어야 함
+   ```bash
+   # Ubuntu/Debian
+   sudo apt-get install timescaledb-postgresql-16
+   ```
+
+2. **기존 데이터 마이그레이션**: `history_table`과 `realtime_table`의 기존 데이터를 새 하이퍼테이블로 이동해야 함
+
+3. **연결 문자열**: `Trust Server Certificate=true`는 TimeScaleDB에서 필요하지 않을 수 있음
+
+4. **EF Core 제한**: EF Core는 TimeScaleDB 하이퍼테이블을 직접 지원하지 않음
+   - Raw SQL 쿼리 활용 필요
+   - `ExecuteSqlRawAsync`, `FromSqlRaw` 사용
+
+5. **백호환성**: 기존 API 엔드포인트는 변경되지 않도록 유지
