# Timeline PDF Notes Parser Use when provided operator notes are only available as PDFs. ## Input Contract - Directory `input/notes/` with `.pdf` files representing operator notes. ## Output - Write `output/pdf_notes_entries.json` with normalized entries (timestamp, source, operator, action, details, raw_timestamp). ## Workflow 1. Use `pdfplumber` to extract text per page and optional tables. 2. Apply the same timestamp patterns as the Markdown parser; use filename-derived dates/operator context when necessary. 3. Normalize timestamps to UTC and drop duplicates flagged by the consolidator. 4. Track page numbers or table origins in `source`/`details` for traceability. 5. Append `source_type = "pdf_notes"` in metadata with counts and errors. 6. Provide guidance to install `pdfplumber` if missing. ## Notes - Tables are optional; parse them to capture structured timeline rows when available. - Handle messy text by cleaning repeated headers/footers.
