# Timeline Ghostwriter Parser Trigger on Ghostwriter CSV oplog exports for timeline ingestion. ## Input Contract - Directory `input/gw_oplog/` with `.csv` files exported from Ghostwriter operation logs. ## Output - Write `output/gw_entries.json` with entries (timestamp, source, operator, action, details, command, output, source_ip, dest_ip, tool, user_context, raw_entry). - Include metadata with `source_type = "ghostwriter"`, processing stats, and errors. ## Workflow 1. Discover CSV files and use `csv.Sniffer` to detect delimiters. 2. Validate required columns (`timestamp`, `operator`, `description`) before parsing. 3. Normalize Ghostwriter timestamps (support ISO 8601, US/EU formats) to `YYYY/MM/DD HH:MM:SS UTC`. 4. Map CSV columns to the standard schema, dedupe entries by `oplog_id`, and record the versioned `source_file`. 5. Capture context such as tool, command, source/dest IPs, and comments. 6. Write `metadata` including counts, files processed, and any CSV parsing issues. ## Notes - Skip empty rows and rows missing both timestamp and description. - Provide example timestamp formats and CSV validation warnings.
