This line loads the entire file into memory before computing recent-change signals, so every dataset with both a date and numeric column incurs an O(n) in-memory copy in addition to profiling; on large CSVs this can significantly slow analysis or trigger memory failures. Since analyze_multiple_csv is otherwise stream-oriented, this regression can break large-file workflows and should be replaced with incremental windowed processing.

Recent-change detection parses numeric cells with float(raw) after only removing commas, which drops values like currency/percent/parenthesized numbers that profiling already treats as numeric via _to_float; in those common formats, dtype is float but prev_vals/recent_vals stay empty and the 최근 급변 reason is silently missed. Reusing the same numeric normalization here would keep reason generation consistent with the profile stage.
