2. Four Filesystem & Compliance Naming Rules (Finance & Accounting β Vendor W-9, 1099 & Fee Schedules)
Selected Pattern Mode: Audit-Standard Chronological ({year}_{doc_code}_{id}_{slug_name}.pdf)
- Automatic Punctuation & Path Sanitization: Commas, periods, slashes, and quotes in entity names (e.g. 'Northstar Logistics, LLC') are automatically normalized to single underscores ('Northstar_Logistics_LLC').
- Zero Filename Collision Guarantee: Including the primary key column ('vendor_id', 'unit_number', 'patient_id', or 'employee_id') guarantees two recipients with identical names never overwrite each other in the ZIP archive.
- Cross-OS Path Length Guard (Windows MAX_PATH & macOS Finder): Individual PDF filenames are capped at 64 ASCII-safe characters so unzipped archives extract cleanly on Windows Server, SharePoint, and macOS.
- Deterministic Audit Manifest (batch_manifest.csv): Every FormBatch ZIP export can pair with a row-by-row CSV manifest logging the exact output filename and SHA-256 checksum prefix for compliance audits.
