Maintenance Imports — Exact Row Duplicates Validator

Choose this endpoint when you need to detect exact (byte-for-byte) duplicate rows in a maintenance import CSV before loading it into a system of record. It is specifically tuned for maintenance domain schemas and supports configurable delimiters, cell length limits, and category allow-lists. Prefer it over generic deduplication tools when working with structured maintenance data CSVs in an automated import pipeline.

• CSV exceeds 100,000 character limit — returns error indicating payload too large
• CSV is empty or malformed — returns parse error
• Delimiter mismatch causes incorrect row parsing — unexpected output with no detected duplicates
• Cell length exceeds max_cell_length setting — row or cell rejected
• More than 1000 rows submitted — operation may be refused or truncated
• Invalid delimiter value outside allowed enum — validation error returned
