Provider temporal and closed-option inputs now reject ambiguous free-form strings at schema validation time instead of letting malformed values reach upstream APIs.

This narrows public provider input schemas for date, time, datetime, and finite routing-option fields so agent/tool layers fail fast before dispatching ambiguous temporal values or unsupported options to upstream services. Existing clients that already send the documented formats continue to work; clients relying on loose strings should normalize before calling the operation.

Update callers to send exact documented wire formats. CatchTable reservation dates and returned availability date_slots use YYYY-MM-DD, and reservation times use HH:MM such as 19:00, not 1900 or 7pm. KakaoMap transit times and KMA base times must use compact HHmm. Naver Map and Modu Parking prediction datetimes must include an ISO 8601 timezone. Naver Flight dates must use YYYY-MM-DD. KakaoMap car priority and transit sort must use the documented enum values.
