1. 🟡 [MEDIUM] Bug in src/cn_equity_snapshot_pipelines/akshare_market_history.py

Changing the guard from if not frames: to if errors: means an empty symbols input now falls through to pd.concat(frames, ignore_index=True), which raises ValueError: No objects to concatenate. Before this patch, the function failed in a controlled way when no frames were produced; after this change, callers that pass an empty list or tuple will get an uncaught crash instead. (line 114)

Suggestion: Restore an explicit empty-result guard before pd.concat, for example by checking if not requested_symbols or if not frames and raising a deterministic RuntimeError/ValueError with a clear message.
