28-44: パフォーマンス改善:HashSetの使用を検討してください。
Vec::containsは O(n) のため、レコード数が多い場合は全体の処理が O(n*m) になります。station_idsとtype_idsをHashSetに変更すると、ルックアップが O(1) になり効率的です。また、2つのループを1つに統合することで、
recordsのイテレーションを1回に削減できます。♻️ 改善案

In `@data_validator/src/main.rs`:
- Around line 74-76: The Markdown table is broken because raw CSV values (e.g.,
in the loop over invalid_station_ids that calls md.push_str(&format!("| `{}`
|\n", line))) are not escaped; create a small helper (e.g.,
escape_markdown_cell) and use it wherever you format CSV values into the
Markdown cells (the loop over invalid_station_ids and the similar loop at lines
88-90) to replace backticks and pipe characters (at minimum replace '`' →
"`" and '|' → "|") before inserting into md.push_str so table cells
never break the Markdown layout.
- Around line 29-44: The loop over records currently accumulates invalid entries
in invalid_station_ids/invalid_type_ids and defers failure; instead modify the
validation within the for record in &records loop (where station_cd and type_cd
are parsed and line() is constructed) to panic immediately upon the first
detection of an unrecognized station or type (i.e., replace pushing to
invalid_station_ids/invalid_type_ids with a panic! that includes a clear message
and the offending line() or IDs). Remove the post-loop has_err check/collection
logic so the program fails fast as soon as station_cd or type_cd validation
fails.

Raw CSV values containing backticks or pipe characters would break the Markdown table layout in the validation report. Add an escape_markdown_cell helper that replaces ` → ` and | → |. https://claude.ai/code/session_01Lr3k5y8UYcH26a8hndo8ek

- Around line 29-41: The loop over records currently uses unwrap() in
record.get(...).unwrap().parse().unwrap() (used to produce station_cd and
type_cd), which can panic on missing columns or parse errors; change the logic
in the for record in &records loop to validate record.get(1) and record.get(2)
and their parse results via pattern matching (e.g., match or if let) instead of
unwrap, and when a get or parse fails push the line() into invalid_station_ids
or invalid_type_ids (as appropriate) and continue processing; keep the existing
line closure and println! messages but replace the unwrap-based assignments for
station_cd and type_cd with safe parsing that records invalid lines rather than
panicking.

Use match with record.get().and_then(parse) instead of chained unwrap() calls for station_cd and type_cd. Missing or unparseable values now log the row and push it into the appropriate invalid list instead of panicking. https://claude.ai/code/session_01Lr3k5y8UYcH26a8hndo8ek
