+## 2026-02-01 - [FastAPI Validation & Exception Handling]
+**Vulnerability:** Not strictly a vulnerability, but a pattern: When replacing explicit type declarations in FastAPI endpoints (e.g. `pair: str`) with custom Dependencies (e.g. `pair: str = Depends(validate)`), if the dependency makes the field optional (returns None) but the Response Model requires it, it causes a `ResponseValidationError` (500 error) instead of `RequestValidationError` (422 error).
+**Learning:** Using `Query(..., pattern=r"...")` directly in the endpoint signature is safer and cleaner than custom Dependencies for simple validation, as it preserves the "required" nature of the field at the interface level and correctly triggers 422 for client errors.
+**Prevention:** Prefer standard FastAPI validation (Pydantic/Query/Path) over custom dependencies for basic type/format checks to ensure correct error status codes.

Subject: [PATCH 6/7] Fix CI failures in security patch
- Fixed line length violations in `tests/rpc/test_api_rate_limit.py` and `tests/rpc/test_api_security.py` (E501)
- Fixed import sorting in `tests/rpc/test_api_rate_limit.py` (isort)
- Applied `ruff format` to modified files to satisfy pre-commit hooks
- Verified tests pass with `python -m pytest`

Subject: [PATCH 7/7] perf: Optimize data processing, exchange caching, and RPC
- Optimize `ohlcv_to_dataframe` timestamp handling and type casting.
- Optimize `clean_ohlcv_dataframe` to skip sorting.
- Cache `Exchange.get_quote_currencies`.
- Optimize `json_to_dataframe` using `rapidjson`.
- Optimize `Telegram._logs` string concatenation.
- Update `tests/data/test_converter.py` to match optimized input expectations.
