docs(signal-v2): amend spread formula to absolute (q90-q10) for Chronos-bolt zero-shot reality

Phase 0 spec §6.1 originally specified relative spread (q90-q10)/median < 0.6.
Phase 3b smoke (005930: median=-0.59%, q90-q10=15.3%) revealed Chronos-bolt
zero-shot median frequently sits near zero, causing relative spread to explode
(15.3/0.0059 ≈ 25) and reject every signal. Absolute spread (0.153 < 0.6)
preserves the threshold semantic and keeps Phase 7 IC validation tractable.

Phase 4 spec §4.2 + Phase 0 §6.1 both amended with cross-reference.
chronos_predictor.py conf calculation unchanged — monotonic mapping there
is independent of hard-gate semantics.

+# Signal V2 Phase 4 — Signal Generator Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** signal_v2 에 매수/매도 신호 생성 레이어 추가. Phase 2/3a/3b 의 모든 state 산출 → Phase 0 spec §6.1-§6.3 룰 → `state.signals[ticker]` (Phase 0 spec §5.2 schema) + `SignalDedup` 24h 차단.
+
+**Architecture:** 순수 함수 `generate_signals(state, dedup, settings)` 가 매 분봉 cycle 후 호출. 매수 (Hard gate 4 조건 + soft confidence > 0.7) + 매도 (손절>이상>익절 우선순위). 6 env 외부화 (운영 튜닝).
+
+**Tech Stack:** Python 순수 함수 / pytest / SignalDedup (Phase 2) / 외부 의존성 없음
+
+**Spec:** `web-ui/docs/superpowers/specs/2026-05-17-signal-v2-phase4-signal-generator.md`

+### Task 1: foundation (config + state)
+
+**Files:**
+- Modify: `web-ai/signal_v2/config.py`
+- Modify: `web-ai/signal_v2/state.py`
+
+- [ ] **Step 1: Update config.py with 6 new fields**
+
+Read `web-ai/signal_v2/config.py`. Add 6 fields to Settings (after `chronos_model` field, before properties):
+
+```python
+    stop_loss_pct: float = field(
+        default_factory=lambda: float(os.getenv("STOP_LOSS_PCT", "-0.07"))
+    )
+    take_profit_pct: float = field(
+        default_factory=lambda: float(os.getenv("TAKE_PROFIT_PCT", "0.15"))
+    )
+    chronos_spread_threshold: float = field(
+        default_factory=lambda: float(os.getenv("CHRONOS_SPREAD_THRESHOLD", "0.6"))
+    )
+    asking_bid_ratio_threshold: float = field(
+        default_factory=lambda: float(os.getenv("ASKING_BID_RATIO_THRESHOLD", "0.6"))
+    )
+    confidence_threshold: float = field(
+        default_factory=lambda: float(os.getenv("CONFIDENCE_THRESHOLD", "0.7"))
+    )
+    min_momentum_for_buy: str = field(
+        default_factory=lambda: os.getenv("MIN_MOMENTUM_FOR_BUY", "strong_up")
+    )
+```
+
+- [ ] **Step 2: Update state.py with signals field**
+
+Read `web-ai/signal_v2/state.py`. Add `signals` field to PollState (after `minute_momentum`):
+
+```python
+    signals: dict[str, dict] = field(default_factory=dict)
+```
+
+- [ ] **Step 3: Smoke import test**
+
+```bash
+cd /c/Users/jaeoh/Desktop/workspace/web-ai
+python -c "from signal_v2.config import get_settings; from signal_v2.state import state; s = get_settings(); print(f'stop_loss={s.stop_loss_pct}, conf_threshold={s.confidence_threshold}, min_momentum={s.min_momentum_for_buy}'); print(state)"
+```
+Expected: `stop_loss=-0.07, conf_threshold=0.7, min_momentum=strong_up` + state print with `signals={}`.
+
+- [ ] **Step 4: Run existing tests — no regression**
+
+```bash
+cd /c/Users/jaeoh/Desktop/workspace/web-ai
+python -m pytest signal_v2/tests -q 2>&1 | tail -3
+```
+Expected: 45 passed.
+
+- [ ] **Step 5: Commit**
+
+```bash
+cd /c/Users/jaeoh/Desktop/workspace/web-ai
+git add signal_v2/config.py signal_v2/state.py
+git commit -m "$(cat <<'EOF'
+feat(signal_v2-phase4): foundation — 6 env thresholds + state.signals

+
+- [ ] **Step 3: Update pull_worker.py — poll_loop signature + cycle integration**
+

+# Confidence Signal Pipeline V2 — Phase 2: web-ai Pull Worker Design
+
+**작성일**: 2026-05-16
+**작성자**: gahusb
+**상태**: Approved for implementation
+**선행 spec**:
+- Phase 0 architecture (`2026-05-15-confidence-signal-pipeline-v2-architecture.md`)
+- Phase 1 stock WebAI API (`2026-05-15-signal-v2-phase1-webai-api.md`)
+- signal_v1 rename (`2026-05-16-web-ai-v1-rename-to-signal-v1.md`) — 본 spec 부터 `web-ai/signal_v1/` + `web-ai/signal_v2/` 구조 사용
+
+**브레인스토밍 결정 6개**:
+- 배치 = A (별도 FastAPI app `:8001`, 새 디렉토리 `web-ai/signal_v2/`)
+- Scope = A (client + scheduler + rate limit DB 3 항목)
+- Scheduler = B (asyncio + 자체 cron loop, FastAPI lifespan)
+- HTTP client = B (httpx async + 자체 retry loop + 메모리 cache)
+- Rate limit DB = A (SQLite + WAL + busy_timeout)
+- Test = B (pytest + pytest-asyncio + httpx mock + tmp_path sqlite)
+

+
+## 1. 목표
+
+web-ai 머신에 V2 신호 파이프라인 인프라 구축. stock NAS 와 안정적으로 통신하는 client + 시간대별 polling scheduler + 24h dedup 인프라.
+
+Phase 3 (Chronos-2 추론) 이 이 위에 추론 코드를 얹는다. Phase 4 (signal generator) 가 rate limit DB 를 사용. Phase 5 에서 같은 FastAPI app 에 `POST /signal` endpoint 추가.
+
+**Why**: Phase 0 §3 책임 분리 — "web-ai = 시점 분석". web-ai 가 NAS DB 직접 접근 안 함, 모든 데이터는 stock API 경유. Phase 1 endpoint (X-WebAI-Key 인증) 가 입력 계약 = Phase 2 의 client 가 이 위에 동작.
+
+---
+
+## 2. 범위
+
+### 포함
+
+- ① **StockClient 클래스** — httpx async + 자체 retry loop (max 3, exponential backoff 1s→2s→4s) + 메모리 dict cache (TTL: portfolio 60s / news-sentiment 300s / screener 60s) + 마지막 성공 응답 stale fallback
+- ② **Polling scheduler** — asyncio cron loop (FastAPI lifespan + asyncio.create_task). 시간대별 분기 (장전 5분 / 장중 1분 / 장후 5분 / 야간·휴장 skip)
+- ③ **Rate limit DB** — SQLite (WAL + busy_timeout=120000) `signal_dedup` 테이블. Phase 4 가 사용
+- ④ **FastAPI app** — 새 port `:8001`. `GET /health` endpoint + startup/shutdown lifespan
+- ⑤ **PollState** — process-wide singleton (portfolio/news_sentiment/screener_preview + last_updated + fetch_errors)
+- ⑥ **테스트 16 케이스** (stock_client 6 + scheduler 5 + rate_limit 3 + main 2)
+
+### 범위 외 (NOT)
+
+- Chronos-2 추론, KIS WebSocket, 분봉 (Phase 3)
+- Signal generator 매수/매도 룰 (Phase 4) — rate limit DB 사용은 Phase 4
+- agent-office `POST /signal` 호출 (Phase 5)
+- 기존 signal_v1 (V1 자동매매) 분리/정리/deprecation (Phase 6)
+- Ollama Qwen3 호스팅 (Phase 5)
+- ticker filter / 운영 모니터링 메트릭 (Phase 7)
+- holidays.json 자동 동기화 (backlog — 일단 stock/app/holidays.json 의 manual copy)
+- 메모리 cache TTL 만료 entry 명시 cleanup (YAGNI)

+## 6. Rate Limit DB
+
+### 6.1 SQLite schema (signal_v2/rate_limit.py 의 startup 시 생성)
+
+```sql

+
+### 6.2 `SignalDedup` 클래스
+
+```python
+class SignalDedup:

+
+## 8. 위험 및 완화
+
+| 위험 | 완화 |
+|------|------|
+| stock API 응답 지연 (NAS 부하 / 네트워크) | timeout 10s + retry 3회 + cache fallback (stale) |
+| `.env` 의 WEBAI_API_KEY 미설정 → 모든 호출 401 | startup ERROR log + Phase 1 의 503 응답 fallback 활용 |
+| Polling cycle 중 web-ai 종료 | shutdown.wait timeout 으로 즉시 break, asyncio cleanup |
+| holidays.json 미동기화 → 휴일 폴링 시도 | stock 측 응답 정상 (데이터 stale). Phase 7 모니터링 |
+| SQLite WAL lock (Phase 4 가 signal generator 동시 write) | busy_timeout=120000 + WAL → reader/writer 분리. Phase 4 단일 writer 직렬 보장 |
+| 메모리 cache 누수 (장기 운영) | TTL 만료 entry 명시 cleanup 없음 (YAGNI). Phase 7 모니터링 |
+| signal_v1 (port 8000) ↔ signal_v2 (port 8001) 충돌 | 다른 port. 같은 머신에서 동시 가동 가능 |
+| 시간대 (KST) 계산 오류 (DST) | KST 는 DST 없음 (Asia/Seoul +09:00 고정). 안전 |
+| asyncio + sqlite3 (sync) 혼합 | rate_limit 호출은 짧음. Phase 4 의 호출 패턴 결정 시 점검 |
+| Phase 1 rate limit (60r/m) 초과 | polling 빈도 분당 3 → 20x 여유. 정상 동작 시 무관 |
+
+---
+
+## 9. 운영 영향
+
+| 항목 | 영향 |
+|------|------|
+| 다운타임 | 0 (V1 영향 없음, V2 신규 시작) |
+| 사용자 영향 | 없음 (V2 silent, Phase 5 까지 신호 발송 없음) |
+| `.env` 갱신 | 사용자 1회 (`WEBAI_API_KEY`, `STOCK_API_URL`, `SIGNAL_V2_PORT`) |
+| V1 영향 | 0 (별도 process / port / 디렉토리) |
+| stock NAS 부하 | 매우 작음 (장중 분당 3 call) |
+| 외부 의존성 추가 | `httpx`, `pytest-asyncio`, `respx` |
+
+---
+
+## 10. Phase 2 완료 조건 (DoD)
+
+- [ ] `web-ai/signal_v2/` 디렉토리 + 7 파이썬 파일 (main.py / config.py / stock_client.py / scheduler.py / pull_worker.py / rate_limit.py / state.py + __init__.py)
+- [ ] `holidays.json` 복사
+- [ ] `tests/` 디렉토리 + conftest.py + 4 test 파일 + 16 케이스 모두 PASS
+- [ ] `python -m uvicorn signal_v2.main:app --port 8001` 정상 시작 + `GET http://localhost:8001/health` 200
+- [ ] 1 회 polling cycle 완료 → `state.portfolio` + `state.news_sentiment` + `state.screener_preview` 갱신 확인 (수동 trigger 또는 첫 자연 cycle)
+- [ ] rate_limit DB 파일 생성 + WAL + busy_timeout 설정 확인
+- [ ] `.env` 갱신 (사용자 1회): `STOCK_API_URL=https://gahusb.synology.me`, `WEBAI_API_KEY=<Phase 1 동일>`, `SIGNAL_V2_PORT=8001`
+- [ ] web-ai V1 봇 무영향 검증 (`start.bat` 정상 시작)
+- [ ] git push (web-ai repo)
+
+---
+
+## 11. Phase 3 와의 관계
+
+본 Phase 2 완료 후 즉시 **Phase 3 (KIS WebSocket + 분봉 + Chronos-2 추론)** spec → plan → 구현. 의존성:
+
+```
+[Phase 2 spec/plan/실행]   →   [Phase 3 spec/plan/실행]
+       2주                          2주
+```
+
+Phase 3 의 입력 계약 = 본 spec 의 `PollState` (Phase 3 코드가 read-only 로 import). Phase 3 의 추론 결과 (Chronos-2 quantile 등) 는 별도 state 객체 또는 PollState 확장 — Phase 3 spec 에서 결정.
+
+---
+
+## 12. Backlog (본 spec NOT)
+
+- ticker filter (news-sentiment `?tickers=` 옵션 활용) — V2 운영 후 종목 필터 시
+- 운영 메트릭 (응답시간 / 에러율 / 텔레그램 alert) — Phase 7
+- holidays.json 자동 동기화 (stock → web-ai)
+- cache 만료 entry 명시 cleanup (장기 운영 시 메모리 누수 발견 시)
+- Phase 5 `POST /signal` endpoint (agent-office 호출) — Phase 5 spec
+- WebSocket-based polling (현재 HTTP polling, 향후 stock 측이 WebSocket push 도입 시)
+- Phase 6 signal_v1 deprecation (V1 자동매매 정리)
+- Phase 4 가 rate_limit 호출 시 asyncio.to_thread vs 직접 호출 결정

+# Confidence Signal Pipeline V2 — Phase 3a: KIS Data Collection Design
+
+**작성일**: 2026-05-16
+**작성자**: gahusb
+**상태**: Approved for implementation
+**선행 spec**:
+- Phase 0 architecture (`2026-05-15-confidence-signal-pipeline-v2-architecture.md`)
+- Phase 1 stock WebAI API (`2026-05-15-signal-v2-phase1-webai-api.md`)
+- signal_v1 rename (`2026-05-16-web-ai-v1-rename-to-signal-v1.md`)
+- Phase 2 web-ai pull worker (`2026-05-16-signal-v2-phase2-web-ai-pull-worker.md`)
+
+**Phase 3 분해**: Phase 0 spec 의 Phase 3 (KIS WebSocket + NXT + Chronos-2 + 분봉 모멘텀) 를 2 sub-phase 로 분해:
+- **Phase 3a (본 spec)**: KIS 데이터 수집 (분봉 REST + 호가 WebSocket + scheduler NXT 확장)
+- **Phase 3b (별도 spec)**: Chronos-2 추론 + 분봉 모멘텀 분류기
+
+**브레인스토밍 결정 6개**:
+- scope = B (3a / 3b 분해)
+- 데이터 수집 = B (분봉 REST + 호가 WebSocket)
+- KIS 인증 = A (V1 토큰 read-only 공유)
+- 구독 범위 = A (portfolio WebSocket + screener REST polling)
+- NXT 처리 = C (stock 자동 처리 + scheduler 의 NXT 시간대 폴링 추가)
+- 테스트 = A (respx REST mock + WebSocket mock + tmp sqlite)
+
+---
+
+## 1. 목표
+
+signal_v2 가 신호 판단에 필요한 KIS 실시간/준실시간 데이터 (분봉 OHLCV + 호가 매수세) 를 수집해 `PollState` 에 채워 넣는다. Phase 3b (Chronos-2 추론) + Phase 4 (signal generator) 가 이 위에 동작.
+
+**Why**: Phase 0 §3 "web-ai = 시점 분석" 책임의 데이터 수집 부분. KIS REST 의 분봉/호가 + KIS WebSocket 의 실시간 호가가 매수/매도 룰의 핵심 입력.
+
+---
+
+## 2. 범위
+
+### 포함 (6 항목)
+
+- ① **KIS REST client** (`signal_v2/kis_client.py`) — 분봉 polling + screener Top-N 호가 polling. V1 토큰 파일 (`signal_v1/data/kis_token.json`) read-only 공유.
+- ② **KIS WebSocket client** (`signal_v2/kis_websocket.py`) — approval_key 신규 발급 + portfolio 보유 종목 호가 실시간 구독 + reconnect with exponential backoff.
+- ③ **`pull_worker.py` 확장** — 분봉 1분 polling cycle 추가 + WebSocket 메시지 처리 task.
+- ④ **`PollState` 확장** — `minute_bars: dict[ticker, deque(maxlen=60)]`, `asking_price: dict[ticker, dict]`, `last_updated["minute_bars"]` / `["asking_price"]`.
+- ⑤ **`scheduler.py` 수정** — NXT 시간대 폴링 (20:00-23:30 / 04:30-07:00) 5분 cron 추가.
+- ⑥ **테스트 13 신규** (KIS REST 4 + WebSocket 4 + scheduler NXT 3 + pull_worker 2). 기존 19 + 신규 13 = 32 total.
+
+### 범위 외 (NOT)
+
+- Chronos-2 모델 로드 + 추론 (Phase 3b)
+- 분봉 모멘텀 분류기 (Phase 3b — 5분봉 aggregate + 5연속 양봉 룰)
+- Signal generator 매수/매도 룰 (Phase 4)
+- NXT 자체 API 호출 — V2 가 별도 NXT API client 없음. stock 측 `price_fetcher` 가 NXT 시간대 가격 자동 반환 (`price_session` 필드)
+- WebSocket 동적 subscribe 갱신 — portfolio 변동 시 다음 cycle 에서 일괄 갱신
+- 분봉 daily aggregate — 60 분봉 sliding window 만
+- 분봉 영속 저장 — 메모리만, 재기동 시 reset
+- V2 자체 KIS 토큰 발급 — Phase 6 deprecation 까지 V1 단독 갱신 책임

+|------|------|
+| V1 토큰 파일 미존재 (V1 미가동) | startup ERROR log + KIS REST 호출 fail. Phase 6 까지 V1 단독 책임 |
+| KIS WebSocket 연결 끊김 | exponential backoff (1s→2s→4s→max 30s) + subscription 재등록 |
+| KIS WebSocket 호가 메시지 형식 변경 | `_parse_asking_price` parse fail → WARNING log + skip. KIS API 변경 시 spec 갱신 |
+| V1 토큰 갱신 race (V1 갱신 중 V2 read) | mtime 캐시 + 짧은 fail 허용 (다음 호출에서 새 token 사용) |
+| approval_key 만료 | 매 reconnect 시 재발급 |
+| KIS REST rate limit (초당 2회) | `_throttle()` 0.5s sleep (V1 패턴) |
+| 분봉 buffer 메모리 누수 | `deque(maxlen=60)` 자동 cap. ticker ~40 → ~200KB |
+| websockets 라이브러리 호환 | `websockets>=12` 명시 |
+| WebSocket subscription / portfolio drift | pull_worker 가 매 cycle 후 비교 + 동적 subscribe/unsubscribe |
+| NXT 시간대 polling 시 stock API 부하 | 5분 cron × portfolio 11 종목 → 분당 ~2 call 무시 가능 |
+| 분봉 데이터 누락 (network 단절) | retry 3회 + cache. 누락 분봉 skip + WARNING |
+| KIS API 점검 시간대 | KIS 점검 (보통 새벽 02:00-04:30) 은 dead zone 시간대와 일치 — 영향 없음 |

+| V1 영향 | 0 (read-only 토큰 공유) |
+| stock NAS 부하 | 무관 |
+| KIS API 부하 | 매 분봉 cycle 분당 ~20 종목 × 2 call (분봉+호가) = 40 call/min ≈ 초당 0.67 < 2 한도 |
+| WebSocket 세션 | 1 세션 / portfolio 보유 종목 (~11) 구독 |

+## 12. Phase 3b 와의 관계
+
+본 Phase 3a 완료 후 즉시 **Phase 3b (Chronos-2 + 분봉 모멘텀)** brainstorming. 의존성:

+```
+[Phase 3a spec/plan/실행]   →   [Phase 3b spec/plan/실행]
+       1주                          1주
+```
+
+Phase 3b 의 입력 = 본 spec 의 `state.minute_bars` + `state.asking_price`. Phase 3b 산출 = `state.chronos_predictions` + `state.minute_momentum` (Phase 4 가 사용).
+
+---
+
+## 13. Backlog (본 spec NOT)
+
+- WebSocket 동적 subscribe (현재 매 cycle 일괄, 즉시 갱신 안 됨)
+- KIS 분봉 60+ 보관 (장기 추세 분석용)
+- 체결 데이터 (`H0STCNT0`) 추가 — 자체 분봉 builder 가능성
+- KIS API 응답 시간 모니터링 (Phase 7)
+- V2 자체 KIS 토큰 갱신 (Phase 6 deprecation 시)
+- WebSocket session 멀티 (41 종목 한도 초과 시)
+- approval_key 만료 자동 감지 (현재는 reconnect 시점)

+# Confidence Signal Pipeline V2 — Phase 3b: Chronos-2 + Minute Momentum Design
+
+**작성일**: 2026-05-16
+**작성자**: gahusb
+**상태**: Approved for implementation
+**선행 spec**:
+- Phase 0 architecture (`2026-05-15-confidence-signal-pipeline-v2-architecture.md`)
+- Phase 1 stock WebAI API (`2026-05-15-signal-v2-phase1-webai-api.md`)
+- Phase 2 web-ai pull worker (`2026-05-16-signal-v2-phase2-web-ai-pull-worker.md`)
+- Phase 3a KIS data collection (`2026-05-16-signal-v2-phase3a-kis-data-collection.md`)
+
+**브레인스토밍 결정 7개**:
+- daily data 소스 = B (KIS REST `kis_client.get_daily_ohlcv`)
+- 추론 빈도 = A (종가 후 1회 + 메모리 보관)
+- 모델 = A (env `CHRONOS_MODEL` 외부화, 기본 `amazon/chronos-2`, 항상 로드)
+- 분봉 모멘텀 = A (5-level 룰 기반)
+- State output = B (median + q10 + q90 + conf + as_of)
+- 테스트 = A (모델 mock + 순수 함수)
+- scope = 통합 9 항목 (Phase 3a 와 같은 1주 단위)
+
+---
+
+## 1. 목표
+
+Phase 3a 의 데이터 위에 추론 레이어 추가. Chronos-2 zero-shot 으로 다음날 가격 분포 예측 + 1분봉 → 5분봉 aggregate 후 5-level 모멘텀 분류. Phase 4 (signal generator) 가 두 출력 + Phase 3a 의 호가/분봉 + Phase 2 의 portfolio/news_sentiment 를 종합해 매수/매도 신호 룰 적용.
+
+**Why**: Phase 0 §3 "web-ai = 시점 분석" 책임의 추론 부분. Chronos-2 의 zero-shot quantile 분포 + 분봉 모멘텀 5-level 이 매수/매도 룰의 핵심 입력.
+
+---
+
+## 2. 범위
+
+### 포함 (9 항목)
+
+- ① `kis_client.get_daily_ohlcv(ticker, days=60)` — KIS REST TR_ID `FHKST03010100`
+- ② `chronos_predictor.py` 신규 — `ChronosPredictor` (HuggingFace 모델 + batch predict)
+- ③ `momentum_classifier.py` 신규 — `aggregate_1min_to_5min` + `classify_minute_momentum`
+- ④ `pull_worker.py` 확장 — `_run_post_close_cycle` + `update_minute_momentum_for_all`
+- ⑤ `scheduler.py` 확장 — `_is_post_close_trigger` (16:00 KST)
+- ⑥ `state.py` 확장 — `daily_ohlcv` + `chronos_predictions` + `minute_momentum`
+- ⑦ `main.py` 확장 — lifespan 에 ChronosPredictor 로드
+- ⑧ `config.py` 확장 — `CHRONOS_MODEL` env
+- ⑨ `requirements.txt` — `transformers>=4.40`, `chronos-forecasting>=1.4`, `torch>=2.0`
+
+### 범위 외 (NOT)
+
+- Signal generator 매수/매도 룰 (Phase 4)
+- agent-office `/signal` 호출 (Phase 5)
+- 모델 재학습/fine-tune — zero-shot only
+- 다중 horizon 예측 — 1-day median 만, 다른 horizon Phase 7
+- 외부 데이터 (yfinance/FDR) — KIS REST 만
+- Chronos lazy load — 항상 로드 (Phase 7 모니터링 후 검토)
+- 분봉 모멘텀 ML 모델 — 룰 기반만 (Phase 7 백테스트 후 ML 검토)
+- WebSocket 동적 subscribe (Phase 3a backlog 그대로)

+핵심:
+- Lazy import (`chronos-forecasting` 무거움)
+- GPU 자동 감지 + FP16 (CUDA) / FP32 (CPU)
+- Batch predict — 30+ 종목 동시 ~1-2초
+- Price → return 변환
+- Confidence — 분포 폭 기반 (좁을수록 1)

+| GPU OOM (Chronos + V1 Ollama 동거) | FP16 ~400MB + Ollama 4GB = 5GB / 15.5GB 여유. Phase 5 Qwen3 추가 시 13.3GB. Phase 6 V1 deprecation 후 해소 |
+| `chronos-forecasting` 호환 (transformers 버전) | 명시 버전. 운영 첫 install 검증 |
+| KIS daily fetch + V1 Macro 동시 → rate limit (EGW00201) | post-close 16:00 트리거 vs V1 Trading Bot 의 장 마감 cycle 충돌 위험. 운영 검증 후 16:05 으로 조정 가능 |
+| Chronos-2 예측 정확도 불확실 | Phase 7 IC 검증 + 신호 hit-rate 추적. 부족 시 model env 변경 또는 Moirai-2.0 |
+| 모멘텀 룰 임계값 (1.5x / 5/5) 보수적 | Phase 7 운영 후 임계값 조정 |
+| 1분봉 60개 미만 (장 시작 1시간 내) | NEUTRAL 폴백. 09:00-10:00 신호 발생 안 함 (운영 허용) |
+| Chronos 모델 다운로드 네트워크 단절 | startup RuntimeError + 운영자 알림 + 재시작. 캐시 후 무관 |
+| daily_ohlcv 메모리 누수 | 종목 ~30 × 60일 ~100B = ~180KB. 무시 |
+| Chronos 추론 시 V1 Ollama 와 동시 GPU 사용 | 일 1회 + 짧음 (~2초). V1 Ollama 의 GPU 점유 사이에 끼어들 가능성 → 일시 deferred. Phase 7 모니터링 |
+

+
+## 10. 운영 영향
+
+| 항목 | 영향 |
+|------|------|
+| 다운타임 | signal_v2 재기동 ~30초 (첫 모델 로드) |
+| 사용자 영향 | 없음 (Phase 3b 도 silent, 신호 발송은 Phase 5) |
+| `.env` 갱신 | optional 1줄 (`CHRONOS_MODEL=amazon/chronos-2` — 기본값과 동일 시 미설정 OK) |
+| V1 영향 | 0 (별도 process). GPU 메모리만 공유 |
+| KIS API 부하 | post-close cycle 일 1회 30 종목 daily fetch ~60 calls. 평소 분봉/호가 cycle 그대로 |
+| 모델 다운로드 | 첫 시작 ~1GB / 캐시 |
+

+
+## 11. Phase 3b 완료 조건 (DoD)
+
+- [ ] `signal_v2/kis_client.py` `get_daily_ohlcv` 메서드 추가

+- [ ] `signal_v2/main.py` lifespan ChronosPredictor 로드
+- [ ] `signal_v2/config.py` `CHRONOS_MODEL` env
+- [ ] `requirements.txt` 3 의존성 추가
+- [ ] 12 신규 테스트 PASS (총 45)
+- [ ] 운영 smoke: signal_v2 시작 → Chronos 모델 로드 성공 → 16:00 post-close cycle 1회 실행 → state.chronos_predictions 갱신 확인
+- [ ] V1 무영향 (GPU OOM 없음)
+- [ ] git push

+
+## 12. Phase 4 와의 관계
+
+본 Phase 3b 완료 후 즉시 **Phase 4 (Signal Generator)** brainstorming. 의존성:
+
+```
+[Phase 3b spec/plan/실행]   →   [Phase 4 spec/plan/실행]
+       1주                          1주
+```
+
+Phase 4 의 입력 = 본 spec 의 `state.chronos_predictions` + `state.minute_momentum` + Phase 3a 의 `state.asking_price` + Phase 2 의 `state.portfolio` + `state.news_sentiment`. Phase 4 산출 = `state.signals[ticker]` (buy/sell decision + confidence).
+

+
+## 13. Backlog (본 spec NOT)
+
+- Chronos lazy load (Phase 5 Qwen3 동거 시 VRAM 압박 검토)
+- 다중 horizon (1-day + 5-day + 20-day)
+- ML 기반 분봉 모멘텀 (현재 룰 기반만)
+- Chronos model A/B (chronos-bolt-base vs chronos-2 비교 실험)
+- KIS daily fetch 의 V1 충돌 회피 — file mutex 또는 V2 별도 app_key
+- Chronos quantile 의 임의 quantile 지원 (현재 q10/q50/q90 만)
+- daily_ohlcv 영속 저장 (재기동 시 reset 회피)

+# Confidence Signal Pipeline V2 — Phase 4: Signal Generator Design
+
+**작성일**: 2026-05-17
+**작성자**: gahusb
+**상태**: Approved for implementation
+**선행 spec**:
+- Phase 0 architecture (`2026-05-15-confidence-signal-pipeline-v2-architecture.md`)
+- Phase 1 stock WebAI API (`2026-05-15-signal-v2-phase1-webai-api.md`)
+- Phase 2 web-ai pull worker (`2026-05-16-signal-v2-phase2-web-ai-pull-worker.md`)
+- Phase 3a KIS data collection (`2026-05-16-signal-v2-phase3a-kis-data-collection.md`)
+- Phase 3b Chronos-2 + momentum (`2026-05-16-signal-v2-phase3b-chronos-momentum.md`)
+
+**브레인스토밍 결정 6개**:
+- scope = A (신호 생성만, Phase 5 가 발송)
+- trigger = A (매 분봉 cycle 후 일괄 평가)
+- minute_score = A (Linear 5-level 1.0/0.7/0.5/0.3/0.0)
+- 임계값 = A+ (6 env 외부화)
+- state.signals schema = A (Phase 0 spec §5.2 그대로)
+- 테스트 = A (9 단위 + 1 integration = 10 신규)
+
+---
+
+## 1. 목표
+
+Phase 2/3a/3b 의 모든 산출을 종합해 Phase 0 spec §6.1/§6.2/§6.3 의 매수/매도/dedup 룰 적용. 임계값 통과한 신호를 `state.signals` 에 저장 + `SignalDedup` 으로 24h 중복 차단.
+
+**Why**: Phase 5 (agent-office) 의 입력 계약 완성. signal_v2 가 자체적으로 매수/매도 신호 생성 → Phase 5 가 발송.
+
+---
+
+## 2. 범위
+
+### 포함 (6 항목)
+
+- ① `signal_generator.py` 신규 — `generate_signals(state, dedup, settings) -> None` (state mutating)
+- ② `config.py` 확장 — 6 env (`STOP_LOSS_PCT`, `TAKE_PROFIT_PCT`, `CHRONOS_SPREAD_THRESHOLD`, `ASKING_BID_RATIO_THRESHOLD`, `CONFIDENCE_THRESHOLD`, `MIN_MOMENTUM_FOR_BUY`)
+- ③ `state.py` 확장 — `signals: dict[str, dict]` (Phase 5 input)
+- ④ `pull_worker.py` 확장 — 매 cycle 후 `generate_signals` 호출 + signature 확장 (dedup + settings)
+- ⑤ `main.py` 의 lifespan poll_task 호출 시 dedup/settings 전달
+- ⑥ 테스트 9 단위 + 1 integration = **10 신규** (45 → 55)
+
+### Phase 4 산출 (Phase 5 input)
+
+`state.signals[ticker]` — Phase 0 spec §5.2 schema:
+```python
+{
+    "ticker": str, "name": str,
+    "action": "buy" | "sell",
+    "confidence_webai": float,
+    "current_price": int,
+    "avg_price": int | None,    # sell 시만
+    "pnl_pct": float | None,

+        "news_reason": str | None,
+    },
+    "as_of": str (ISO),
+}
+```
+
+### 범위 외 (NOT)
+
+- agent-office `/signal` HTTP POST (Phase 5)
+- Qwen3 검증 + 이중 텔레그램 (Phase 5)
+- 호가 변경 시 즉시 매도 trigger (Phase 7 backlog)
+- 자동 매매 (Phase 8 backlog)
+- ML 기반 룰 변종 (Phase 7 백테스트 후)
+- `kospi_change`, `news_top` 컨텍스트 (Phase 7 backlog)
+- 외부 API 호출 — Phase 4 는 state 만 사용 (pure function)

+## 3. 파일 구조 + 변경 매트릭스
+
+| 파일 | 작업 | 라인 |
+|------|------|------|
+| `signal_v2/signal_generator.py` | 신규 (generate_signals + 5 helpers) | ~250 |
+| `signal_v2/config.py` | Settings 6 field 추가 | +15 |

+| `signal_v2/pull_worker.py` | poll_loop signature + 매 cycle 호출 | +10 |
+| `signal_v2/main.py` | lifespan poll_task 인자 추가 | +3 |
+| `signal_v2/tests/test_signal_generator.py` | 9 단위 신규 | ~350 |
+| `signal_v2/tests/test_pull_worker.py` | 1 integration 추가 | +50 |
+
+**합계**: 7 파일 변경, 10 신규 테스트.
+
+### 외부 의존성 신규
+
+**없음**. signal_generator 는 순수 함수, 외부 라이브러리 0.
+
+### 6 신규 env
+
+| env | 기본값 | 의미 |
+|-----|--------|------|
+| `STOP_LOSS_PCT` | `-0.07` | 손절선 비율. `pnl_pct < 이 값` → 즉시 매도 |
+| `TAKE_PROFIT_PCT` | `0.15` | 익절선 비율. `pnl_pct > 이 값` → 검토 알림 |
+| `CHRONOS_SPREAD_THRESHOLD` | `0.6` | `(q90-q10)/max(|median|, 0.001) < 이 값` → 매수 통과 |
+| `ASKING_BID_RATIO_THRESHOLD` | `0.6` | `bid_ratio >= 이 값` → 매수 통과 |
+| `CONFIDENCE_THRESHOLD` | `0.7` | `confidence_webai > 이 값` → 신호 발생 |
+| `MIN_MOMENTUM_FOR_BUY` | `strong_up` | 분봉 모멘텀 카테고리 |
+
+---
+
+## 4. 매수 룰 + Confidence
+
+### 4.1 매수 룰 대상
+
+- screener Top-N (`state.screener_preview.items`)
+- portfolio 보유 종목 (추가 매수 검토, dedup 으로 중복 차단)
+
+### 4.2 Hard gate (모든 조건 충족)
+
+1. `state.chronos_predictions[ticker].median > 0` (다음날 상승)
+2. `(q90 - q10) < settings.chronos_spread_threshold` (**absolute spread** — Phase 3b 실 운영 데이터 기반 변경)
+3. `state.minute_momentum[ticker] == settings.min_momentum_for_buy` (기본 strong_up)
+4. `state.asking_price[ticker].bid_ratio >= settings.asking_bid_ratio_threshold`
+
+**Spread formula 결정 노트 (2026-05-17 implementer 변경 채택)**:
+- Phase 0 spec §6.1 의 한국어 "(90-10 분위수) / 50 분위수 < 0.6" 은 *relative spread* 로 명시되었으나, Phase 3b 실 운영 결과 (Chronos zero-shot prediction 의 median 이 종종 0 가까이) 에서 relative formula 가 거의 모든 신호 거부 → useless.
+- **변경**: absolute spread `(q90 - q10) < 0.6` 사용. 0.6 = 60% 변동 예측 — 한국 주식 1-day 변동성 (1-2%) 대비 매우 넓음 (모델 자신 없음 신호).
+- 결과: Phase 3b smoke 005930 (median=-0.59%, q10=-8.9%, q90=6.4%, spread=15.3%) → spread 0.153 < 0.6 → hard gate 통과 가능 (다른 조건 충족 시).
+- Phase 7 IC 검증 시 임계값 재조정 가능 (env `CHRONOS_SPREAD_THRESHOLD`).
+
+### 4.3 Soft confidence (Phase 0 spec §6.1)
+
+```python
+chronos_conf = state.chronos_predictions[ticker]["conf"]
+minute_score = MOMENTUM_SCORES[state.minute_momentum[ticker]]
+# MOMENTUM_SCORES = {"strong_up": 1.0, "weak_up": 0.7, "neutral": 0.5,
+#                    "weak_down": 0.3, "strong_down": 0.0}
+screener_norm = 1 - (rank - 1) / 20 if rank is not None else 0.0
+confidence_webai = chronos_conf * 0.5 + minute_score * 0.3 + screener_norm * 0.2
+```
+
+### 4.4 임계값
+
+`confidence_webai > settings.confidence_threshold` (기본 0.7) → 신호 발생.
+
+### 4.5 누락 처리
+
+- portfolio (Top-N 외) 매수: `screener_rank = None` → `screener_norm = 0` (보수적)
+- `chronos_predictions[ticker]` 누락 → silent (Hard gate 위반)
+- `asking_price[ticker]` 누락 → silent
+
+---
+
+## 5. 매도 룰 + Dedup
+
+### 5.1 매도 대상
+
+portfolio holdings 만 (`state.portfolio.holdings`).
+
+### 5.2 매도 룰 (Phase 0 spec §6.2)
+
+**(a) 손절선 (즉시 trigger)**:
+- `pnl_pct < settings.stop_loss_pct` (기본 -0.07)
+- 다른 룰 무관 — 즉시 매도
+- `confidence_webai = 1.0`
+
+**(b) 익절선 (검토 알림)**:
+- `pnl_pct > settings.take_profit_pct` (기본 0.15)
+- "검토 권고" — 강제 매도 X
+- `confidence_webai = 0.6`
+
+**(c) 이상 신호**:
+- `chronos_predictions[ticker].median < -0.01`
+- `minute_momentum[ticker] == "strong_down"`
+- `asking_price[ticker].bid_ratio < (1 - settings.asking_bid_ratio_threshold)` (매도세 ≥ 60%)
+- confidence_webai = chronos_conf × 0.5 + inverted_minute × 0.3 + 1.0 × 0.2
+- 임계값 > `settings.confidence_threshold`
+
+### 5.3 우선순위 (같은 ticker 다중 trigger 시)
+
+1. **손절** (Phase 0 spec §6.2 "즉시") — 다른 룰 우회
+2. **이상 신호**
+3. **익절선**
+
+상위 trigger 시 하위 skip (한 종목당 한 cycle 1 매도 신호).
+
+### 5.4 Dedup (Phase 0 spec §6.3 + Phase 2 SignalDedup)
+
+```python
+if dedup.is_recent(ticker, action, within_hours=24):
+    continue  # silent
+# 신호 dict 생성
+state.signals[ticker] = {...}
+dedup.record(ticker, action, confidence=confidence_webai)
+```
+
+Dedup 키 `(ticker, action)` — 같은 종목의 매수/매도 별도 추적, 충돌 없음.
+
+손절선도 dedup 적용 (Phase 0 spec §6.3 "1일 1회 max").
+
+---
+
+## 6. State 통합 + pull_worker
+
+### 6.1 PollState 확장
+
+```python
+signals: dict[str, dict] = field(default_factory=dict)
+```
+
+매 cycle 마다 **덮어쓰기 X** — 같은 ticker key 재발생 시 갱신, 그 외 유지. dedup 으로 중복 차단되므로 누적 안전. Phase 5 consumer 가 처리 후 본인 측 dedup.
+
+### 6.2 pull_worker 흐름
+
+```python

+

+
+## 9. 위험 / 운영 / DoD
+
+### 9.1 위험 매트릭스
+
+| 위험 | 완화 |
+|------|------|
+| Phase 0 spec 의 confidence 공식이 실 운영과 안 맞음 | 6 env 외부화 → Phase 7 IC 검증 후 .env 조정 |
+| Chronos 누락 (장 시작 첫 cycle) | Hard gate 위반 → silent. 종가 cron 후 매수 신호 가능 |
+| Dedup DB 손상 | WAL + busy_timeout. 운영자 manual 복구 (signal_v2.db 삭제) |
+| 동시 cycle 에서 같은 종목 buy + sell trigger | dedup PK `(ticker, action)` 별도 추적 — 충돌 없음 |
+| portfolio 매수 → screener_norm=0 → 신호 발생 어려움 | 보수적. 다른 component 높아야 신호. 의도된 동작 |
+| 손절선 trigger 후 24h 추가 손실 → 다음 알림 차단 | 운영적 허용 (Phase 0 spec §6.3 1일 1회 max) |
+| 신호 빈도 너무 적음 | 4주 IC 검증 + 임계값 완화 |
+| 신호 빈도 너무 많음 (false positive) | dedup + 임계값 강화. Phase 7 |
+| 매도 우선순위 잘못 (손절 > 이상 > 익절) | 테스트 케이스로 검증 + 코드 명시 |
+| signals dict 누적 (cycle 사이 stale entry) | dedup 으로 중복 차단되므로 안전. Phase 5 consumer 가 처리 후 본인 측 marker |
+
+### 9.2 운영 영향
+
+| 항목 | 영향 |
+|------|------|
+| 다운타임 | signal_v2 재기동 ~5초 |
+| 사용자 영향 | 없음 (Phase 5 까지 발송 없음) |
+| `.env` 갱신 | optional 0-6개 (기본값 충분) |
+| V1 영향 | 0 |
+| KIS API 부하 | 0 (Phase 4 는 외부 호출 없음) |
+
+### 9.3 Phase 4 완료 조건 (DoD)
+
+- [ ] `signal_v2/signal_generator.py` 신규 (generate_signals + 8 helpers)
+- [ ] `signal_v2/config.py` Settings 에 6 field 추가 (default 있음)
+- [ ] `signal_v2/state.py` PollState `signals` field
+- [ ] `signal_v2/pull_worker.py` poll_loop signature + 매 cycle 호출
+- [ ] `signal_v2/main.py` lifespan 의 poll_task 인자 (dedup, settings) 추가
+- [ ] 9 단위 + 1 integration 테스트 PASS (총 55)
+- [ ] 운영 smoke: signal_v2 시작 → 1 cycle 후 state.signals 빈 dict (운영 시간대 신호 발생 가능 종목 없을 시 정상) 또는 ≥ 1 신호 생성
+- [ ] V1 무영향
+- [ ] git push
+
+---
+
+## 10. Phase 5 와의 관계
+
+본 Phase 4 완료 후 즉시 **Phase 5 (agent-office /signal + Qwen3 + 이중 텔레그램)** brainstorming. 의존성:
+
+```
+[Phase 4 spec/plan/실행]   →   [Phase 5 spec/plan/실행]
+       3-5일                       2주
+```
+
+Phase 5 의 입력 = 본 spec 의 `state.signals[ticker]` (state polling 또는 HTTP push). Phase 5 작업:
+- agent-office `/signal` endpoint 신설 (Phase 0 spec §5.2 schema 수신)
+- web-ai → agent-office HTTP client 추가 (signal_v2 측)
+- web-ai 의 Ollama Qwen3 14B Q4 설치 + agent-office 의 LLM 검증 호출
+- 이중 텔레그램 (본인 풀 / 아내 lite)
+
+---
+
+## 11. Backlog (본 spec NOT)
+
+- 호가 변경 시 즉시 매도 trigger — Phase 7 운영 후 검토
+- `kospi_change` 컨텍스트 (KIS 지수 fetch) — Phase 7
+- `news_top` 컨텍스트 (news_sentiment.reason 다중 추출) — Phase 7
+- 매수/매도 ML 룰 — Phase 7 백테스트 후
+- portfolio 매수의 screener_norm fallback (다른 default 값) — IC 검증 후
+- 신호 hit-rate 대시보드 — Phase 7
+- 분할 매수/매도 전략 — Phase 7 이후
+- 자동 매매 (실주문) — Phase 8
+- 손절선 dedup 면제 (즉시성 위해) — Phase 7 운영 검증 후
