44888d6ede feat(signal_v2-phase3b): main.py lifespan loads ChronosPredictor 
AppContext.chronos field. lifespan: if KIS_APP_KEY set, load
ChronosPredictor(model_name=settings.chronos_model). Exceptions
during load logged + signal_v2 continues without chronos (other
endpoints unaffected). poll_loop receives chronos param.

45 tests pass.

9e5fecb369 feat(signal_v2-phase3b): post-close cycle + minute momentum update 
scheduler._is_post_close_trigger: 16:00 KST ±1min detection (market day).
pull_worker:
- _run_post_close_cycle: daily fetch (60일) + chronos batch predict →
  state.chronos_predictions + state.daily_ohlcv.
- update_minute_momentum_for_all: 매 cycle 마다 state.minute_momentum 갱신.
- poll_loop signature 확장 (chronos optional).

45 tests pass.

28f9c8c3a6 feat(signal_v2-phase3b): chronos_predictor + 4 mock tests 
ChronosPredictor wraps HuggingFace ChronosPipeline. Batch predict
returns ChronosPrediction(median, q10, q90, conf, as_of) per ticker.
Confidence = 1 - clamp(spread/2, 0, 1) where spread = (q90-q10) / |median|.
Lazy import of chronos lib (heavy). GPU auto-detect with FP16.

44 tests pass.

b690900cfc fix(signal_v2-phase3a): V1 KIS env pattern + test isolation fix 
config.py: kis_env_type (virtual/real) + KIS_REAL_*/KIS_VIRTUAL_* env
variables (V1 호환). kis_app_key/kis_app_secret/kis_account properties
auto-select based on env type.

main.py: KIS not-configured warning uses descriptive message including
env type + expected var name.

test_main.py: monkeypatch load_dotenv to no-op + setenv empty string
(instead of delenv) — defeats .env re-read on importlib.reload.
Pre-existing test_startup_warns_if_webai_api_key_missing also fixed.

33/33 tests pass (was 31/33).

d85512d036 feat(signal_v2-phase3a): main.py lifespan integrates KIS client + WS 
AppContext extended with kis_client + kis_ws. lifespan:
- If KIS_APP_KEY set: create KISClient + KISWebSocket, fetch portfolio,
  subscribe WebSocket H0STASP0 for holdings.
- If unset: WARNING log, signal_v2 still serves /health (no KIS data).
- Shutdown closes kis_ws → kis_client → stock client in order.

e47947fb69 fix(signal_v2): await cancelled poll_task + public cache_size 
Code review fixes:
- main.py lifespan: await poll_task after cancel() to avoid client
  close racing with mid-fetch task (CRITICAL).
- stock_client: add public cache_size() method; main.py /health uses
  it instead of private _cache attribute (IMPORTANT).

19 tests still pass. Deferred to Phase 7 backlog:
- _ctx singleton test isolation (importlib.reload provides isolation in practice)
- poll_loop interval floor (interval >= 60 by design)
- shutdown logging
- response schema validation

90235497ae refactor(signal_v2): narrow stock_client exception catch + remove dead code 
Code quality review fixes:
- _cached_request: catch httpx.HTTPError instead of bare Exception
  (avoid swallowing KeyboardInterrupt / asyncio.CancelledError)
- _request_with_retry: remove unused last_exc variable + dead post-loop
  raise paths. Final sentinel raise preserved for mypy.

6 tests still pass. Deferred to Phase 7 backlog: cache concurrency
coalescing + __aenter__/__aexit__ context manager support.

X-WebAI-Key auth header injection. Stale fallback returns last
successful response with logger.warning on persistent failures.
