Remove example*.py from version control (leaked API keys)

example_async_kiwoom.py / example_async_v1.py / example_v1.py에 실제
APP_KEY/APP_SECRET 값이 하드코딩되어 있던 것을 뒤늦게 발견. 정리 후 다시
올릴 예정이라 우선 git 추적에서 제외(로컬 파일은 유지). 이어서 과거
히스토리에서도 완전히 제거함.

+
+## Project overview
+
+`finestock` is a Python package unifying Korean stock brokerage OpenAPIs (EBest, LS, KIS, Kiwoom, NH — live and mock/simulated variants) behind one facade object. It wraps each broker's REST/WebSocket API and normalizes results into shared dataclasses (`Price`, `OrderBook`, `Account`, `Order`, `Trade`, ...).
+
+## Commands
+
+```bash
+pip install -e .              # install package in editable mode (requirements: websockets, requests, loguru)
+python -m unittest discover tests   # run tests (unittest, not pytest — no pytest config in repo)
+python -m unittest tests.test_model -v   # run a single test module
+```
+
+There is no lint/format tooling configured in the repo.
+
+## Architecture
+
+### Facade + Factory + ISP
+
+`finestock.create_api(APIProvider.X)` (thin wrapper around `APIFactory.create_api`, in `finestock/api_factory.py`) lazy-imports and instantiates one broker class. Every broker class multiply-inherits `BaseProvider` (`finestock/comm/api_interface.py`), a union of segregated `ABC` interfaces:
+
+- `AuthenticationProvider` — oauth/token handling
+- `MarketDataProvider` — price/OHLCV/index/orderbook queries
+- `TradingProvider` — order placement/cancellation
+- `RealtimeProvider` — WebSocket subscribe/unsubscribe (`recv_price`, `recv_orderbook`, etc.)
+- `AccountProvider` — balance/holdings
+- `InfoProvider` — stock/index master lists
+
+Callers narrow the fat facade object to one interface via type hints (`market_api: MarketDataProvider = full_api`) purely for IDE autocomplete — there is no runtime restriction. When adding a method, add it to the relevant interface in `api_interface.py` first, then implement it in each concrete broker.
+
+### Class hierarchy per broker
+
+Each broker directory (`finestock/{ebest,ls,kis,kiwoom,nh}/`) has a real/live class and, in most cases, a mock-trading (`*V`) subclass that only overrides `DOMAIN`/`DOMAIN_WS` (via `finestock/path.py`) or a handful of TR IDs:
+
+- `finestock.comm.api.API` — shared base (`finestock/comm/api.py`): holds `app_key`/`app_secret`/`access_token`, generic `headers` dict, generic `oauth()` (client_credentials POST), and `set_data_queue`/`add_data` for realtime fan-out.
+- `LS(API)` — the fullest, canonical implementation (`finestock/ls/ls.py`, ~860 lines): TR-code-based REST calls (`t8410`, `t8407`, `t8452`, ...) plus a WebSocket `connect`/`run`/`recv_*` loop keyed by `tr_cd`.
+  - `EBest(LS)` — EBest's API is wire-compatible with LS, so it inherits everything and only swaps `DOMAIN`/`DOMAIN_WS` via `path.py`.
+  - `LSV(LS)` — LS mock trading; same overrides pattern.
+- `Kis(API)` (`finestock/kis/kis.py`) — KIS uses `tr_id` header-based REST TRs.
+  - `KisV(Kis)` — mock trading; overrides `get_balance`/`do_order` with VTS-prefixed `tr_id`s (`VTTC...` vs `TTTC...`).
+- `Kiwoom(API)` (`finestock/kiwoom/kiwoom.py`, ~850 lines) — Kiwoom's REST+WS shape differs most from the others (`api-id` header instead of `tr_cd`/`tr_id`, `trnm`/`REG` WS subscription protocol).
+  - `KiwoomV(Kiwoom)` — mock trading, `DOMAIN`/`DOMAIN_WS` swapped to `mockapi.kiwoom.com`.
+- `Nh(API)` (`finestock/nh/nh.py`) — NH투자증권(나무/Namuh) uses a uniform `POST {"Input_0": {...}}` → `{rsp_cd, Output_0[, Output_1, Output_2], message}` envelope for every REST TR, auth via `Authorization`/`x-client-id`/`x-client-secret` headers (`set_oauth_info` overridden to set the latter two). No dedicated 호가/지수 TRs — `get_orderbook` reuses the `currentPrice` TR's `askp1..10`/`bidp1..10` fields, and `get_index`/`get_index_list`/`get_stock_list` are unimplemented stubs (지수 TR 없음; 종목은 REST가 아니라 `.mst` 마스터 파일로만 제공). `oauth()` always targets the fixed live domain (`OAUTH_DOMAIN` in `path.py`) even for `NhV`, since 접근토큰발급 is live-only regardless of which domain trades run against.
+  - `NhV(Nh)` — mock trading (`moapi.nhplug.com`); no method overrides needed, only `DOMAIN`/`DOMAIN_WS` swapped via `path.py`.
+
+`finestock/path.py` centralizes all per-broker base URLs and endpoint path fragments in dict constants (`_LS_`, `_KIS_`, `_KIWOOM_`, ...) merged into `_API_PATH_`, keyed by class name; `API._init_path()` reads `_API_PATH_[self.api_type]` and sets each entry as an instance attribute (so `self.DOMAIN`, `self.CHART`, `self.ORDER`, etc. exist post-`__init__`). When adding a broker or endpoint, edit `path.py`, not the broker class, unless the URL needs runtime logic.
+
+### Data models (`finestock/model/`)
+
+All public dataclasses are frozen (`@dataclass(frozen=True)`) and re-exported through `finestock/model/__init__.py` and top-level `finestock/__init__.py`. Broker methods parse raw JSON/TR responses and construct these dataclasses directly (e.g. `finestock.Price(...)`, `finestock.Order(...)`) rather than returning raw dicts — new broker code should follow the same convention. `Price.from_values` / `Price.from_series` are the two supported construction paths for `Price` beyond the raw constructor.
+
+### Realtime data flow
+
+Realtime WebSocket data does not use callbacks; a caller injects a `queue.Queue`-like object via `set_data_queue()` (in `comm/api.py`), and broker WS loops (`LS.run`, `Kiwoom.run`) push parsed messages onto it via `add_data`/`add_price`/`add_trade`/`add_orderbook`. Broker-specific TR/type codes in the incoming WS frame determine how a message is parsed and dispatched.
+
+## Conventions worth knowing
+
+- Continuation/pagination in REST calls follows a broker-specific `cts_date`/`cts_time`/`tr_cont_key` (LS, Kiwoom) or `CTX_AREA_FK100`/`NK100` (KIS) pattern — recursive calls with `time.sleep()` between pages are the existing pattern for LS's `get_ohlcv`.
+- Method names are standardized across brokers per `CHANGELOG.md` (PEP 8, single-underscore private prefix, `do_order_cancel` not `do_order_cancle`) — but `KisV.do_order_cancle` (kis_v.py) still uses the old misspelled name and is a stub (`pass`); don't assume it matches the interface's `do_order_cancel` without checking.
+- `debug.log` at the repo root is loguru output, not source.

+## 환경변수 설정 (.env)
+
+브로커 앱키/시크릿/계좌번호/액세스 토큰은 코드에 직접 하드코딩하지 말고 환경변수로 주입한다. 저장소 루트의 `.env.example`을 복사해 `.env`로 만들고 실제 값을 채워 넣는다.
+
+```bash
+cp .env.example .env
+```
+
+`.env` 파일 내용:
+
+```
+APP_KEY=YOUR_APP_KEY
+APP_SECRET=YOUR_APP_SECRET
+ACCOUNT_NUM=YOUR_ACCOUNT_NUM
+ACCOUNT_NUM_SUB=01
+ACCESS_TOKEN=
+```
+
+`.env`는 `.gitignore`에 의해 커밋되지 않는다(`.env.example`만 커밋 대상).
+
+### 값 로드 방법
+
+`example.py`, `example_async.py`는 모두 `os.environ.get("APP_KEY", ...)` 형태로 값을 읽는다. `.env` 파일 자체는 셸이나 파이썬이 자동으로 읽어주지 않으므로 아래 두 방법 중 하나가 필요하다.
+
+**1) python-dotenv로 자동 로드 (권장)**
+
+```bash
+pip install python-dotenv
+```
+
+예제 스크립트는 `python-dotenv`가 설치되어 있으면 시작 시 자동으로 `.env`를 읽어 `os.environ`에 채워 넣는다(설치돼 있지 않으면 조용히 건너뛴다). 직접 스크립트를 작성할 때도 아래처럼 최상단에서 호출하면 된다.
+
+```python
+from dotenv import load_dotenv
+load_dotenv()
+
+import os
+app_key = os.environ.get("APP_KEY")
+app_secret = os.environ.get("APP_SECRET")
+```
+
+**2) 셸에서 직접 환경변수 설정**
+
+```powershell
+# PowerShell
+$env:APP_KEY = "YOUR_APP_KEY"
+$env:APP_SECRET = "YOUR_APP_SECRET"
+python example.py
+```
+
+```bash
+# bash
+export APP_KEY="YOUR_APP_KEY"
+export APP_SECRET="YOUR_APP_SECRET"
+python example.py
