# Claude Session Summary — 2026-03-27

## Objective
Reconstruct the Dataforth test datasheet pipeline after AD2 crypto wipe. Unblock customer shipment (Quatronix/China, 73 datasheets needed urgently).

## Key Accomplishments

### Pipeline Analysis
- Mapped complete 5-stage pipeline: DOS test stations → NAS → AD2 sync → DFWDS → website
- Identified CTONWTXT.BAT gap (TXT files stuck on DOS machines since Sept 2025)
- Confirmed DFWDS.exe config lost in wipe, old website upload endpoints dead (404)
- Found production config + VB6 source on ENGR share

### New Pipeline Built (C:\Shares\testdatadb\)
- **Spec Parser** (parsers/spec-reader.js): Reads 8 binary spec DAT files, 1470 models
- **Exact-Match Formatter** (templates/datasheet-exact.js): Reverse-engineered from QuickBASIC source
- **Export System** (database/export-datasheets.js): Auto-generates TXT to X:\For_Web after import
- **PDF On-Demand** (routes/api.js): /api/datasheet/:id/pdf endpoint
- **UI Improvements**: ALL filter, auto-search, PDF download button, export status display

### Data Reconciliation
- 1,436,007 DB records matched to existing For_Web files and marked as exported
- 500,419 pre-2026 files archived into year subfolders (X:\For_Web\2013\, etc.)
- Added forweb_exported_at and datasheet_exported_at tracking columns

### Customer Issue Resolved
- Generated 72 of 73 requested datasheets (TXT + PDF) for Quatronix
- Located on Desktop\Quatronix-Datasheets\
- 1 remaining (177000-15, SCM5B49-05) needs empty spec file from John

### Infrastructure Fixes
- Opened firewall on HGHAUBNER for SMB access
- Fixed TestDataDB search defaulting to today's date
- Identified testdatadb Windows service permission issues (SYSTEM vs sysadmin)

## Files Created/Modified
See project_pipeline_rebuilt.md for full list.

## Open Items
1. Website upload replacement (old ASP.NET endpoints dead)
2. 7B datasheet formatting (specs loaded, formatter needs 7B-specific layout)
3. SCM5B49 spec file empty — need from John
4. MAQ20/PWRM10 integration (XLS format, different pipeline)
5. 10D integration (JSON format, ~2 months out)
6. Service permissions cleanup (runs as SYSTEM)
7. Serial numbering standards discussion with John
