## Step-by-Step Local In-Browser Workflow
1. **Drop 94-Byte NACHA (.ach / .txt) Batch File**: Load any standard NACHA PPD, CCD, WEB, or CTX batch file directly into local browser memory—zero server upload.
2. **Select Column-Locked Masking Intensity (35% / 70% / 95%)**: Choose between Last-4 DFI Account masking, Standard DFI + Name + Tax ID scrubbing, or Full Safe-Harbor ABA Routing + Control Hash anonymization.
3. **Inspect 94-Byte Column Alignment & Entry Hash Matrix**: Verify side-by-side in the live Canvas 2D matrix that every Type 1/5/6/7/8/9 record maintains exact 94-character width and valid ABA checksums.
4. **Export Sanitized NACHA Fixture or Launch Offline PRO**: Copy or download the 70% free sanitized ACH batch immediately, or unlock the $19 air-gapped Offline PRO HTML5 Workstation.

## Frequently Asked Questions (Direct Citation Q&A)
### Q: Does scrubbing DFI account numbers or names break the 94-character fixed-width NACHA format?
A: Never. Our engine operates on exact NACHA column slices (e.g., Cols 13-29 for DFI Account Number, Cols 40-54 for Individual ID, Cols 55-76 for Individual Name) and pads or truncates every replacement to the exact field width so every line remains strictly 94 bytes.

### Q: Are my raw NACHA ACH payroll or vendor batch files ever uploaded to a server?
A: No. 100% of parsing, ABA routing checksum calculation, and DFI account masking execute locally inside your browser's memory (RAM). Zero network requests are made with your payload.

### Q: How does the scrubber handle Batch Control (Type 8) and File Control (Type 9) Entry Hashes?
A: When Receiving DFI routing numbers (Cols 04-11 of Type 6 records) are anonymized in Safe-Harbor mode, the engine automatically recalculates the 10-digit Entry Hash in Record Type 8 (Cols 22-31) and Record Type 9 (Cols 22-31) so bank file validators pass without checksum errors.

### Q: What is the difference between the Free 70% Sandbox, the €3.99 Sprint Pass, and the $19 PRO Workstation?
A: The Free Sandbox lets you interactively scrub, copy, and download the first 70% of records in browser RAM. The €3.99 7-Day Sprint Pass unlocks 100% unblurred browser export, and the $19 One-Time Commercial Buyout includes the self-contained air-gapped Offline PRO HTML5 Workstation with 4 specialized NACHA batch modes.
