# Session Log - AD2 - 2026-04-03

## Session Summary

Continued test datasheet pipeline work from the 03-27/28/29 session. Major focus on:
1. Fixing formatting issues in generated TXT datasheets (column alignment matching QuickBASIC)
2. Adding 7B product family support to the exact-match formatter
3. Loading additional spec files (5B49_2.DAT for the last missing Quatronix datasheet)
4. Work order report ingestion (33K WOs, 63K lines, 2.27M records linked)
5. UI improvements (WO search, WO detail popup, View button styled HTML)
6. Generating full Dataforth audit document
7. Planning and beginning PostgreSQL migration (SQLite hitting 4.4GB, queries timing out)
8. Uninstalling SQL Server Express, installing PostgreSQL 18

## Key Decisions
- PostgreSQL over SQL Server Express (no 10GB limit, better FTS, no licensing)
- Install PG locally on AD2 (not SAGE-SQL or new VM)
- Clean cutover (no parallel run with SQLite)
- MSSQL Express uninstalled to free resources

## Work Completed

### Formatting Fixes (datasheet-exact.js)
- Compared generated TXT against originals from X:\For_Web\2025\
- Fixed Final Test Results column alignment to match QB TAB positions:
  - TAB(5) param name, TAB(31) measured value, TAB(60-speclen) spec, TAB(61) unit, TAB(71) PASS/FAIL
- Added setCol() and padToCol() helpers for exact column positioning
- Fixed STR$() emulation: leading space for positive, drops leading zero (.03 not 0.03)
- Fixed header spacing (Date, Model, SN fields)
- Fixed checklist spacing to match QB TAB(45)
- Fixed separator line length (23 chars not 24)

### 7B Product Family Support
- Added SCM7B DATA_LINES (31 parameters vs 20 for SCM5B)
- Added SCM7B TSPECS (supply current, linearity, accuracy, excitation, CJC, noise, etc.)
- Added 7B raw_data parser (single CSV line format vs multi-line for other families)
- 7B-specific footer: 120VAC (not 240), "Packing Check List" (not "Check List"), blank checkmarks, Tested by/QC lines
- Accuracy section suppressed for 7B (DAT format doesn't include individual test points)
- 7B model names prepend "SCM" in header

### Additional Spec File: 5B49_2.DAT
- 5B49DATA.DAT was 0 bytes (empty), John pointed to 5B49_2.DAT
- 15 models, 93 bytes/record, added SCM5B49_FIELDS to spec-reader.js
- Completed final missing Quatronix datasheet (177000-15, SCM5B49-05)
- All 73/73 Quatronix datasheets now generated

### View Button Enhancement
- /api/datasheet/:id now uses exact-match formatter with styled HTML
- White page on gray background, monospace font, print-optimized
- Includes Print and Download PDF buttons
- Falls back to generic template if exact-match not available

### PDF Endpoint Fallback
- /api/datasheet/:id/pdf falls back to generic template when exact-match fails
- Prevents 422 errors for unsupported families

### Work Order Reports
- Created parsers/wo-report.js (parses WO status report TXT format)
- Created database/import-work-orders.js (imports WOs, creates tables, links to test records)
- Created work_orders table (33,745 records) and work_order_lines table (63,263 records)
- Added work_order column to test_records, 2,277,183 records linked via serial number pattern
- Added /api/workorder/:wo and /api/workorder-search endpoints
- Added WO# search field and clickable WO link in UI detail view
- WO detail popup shows all test lines, pass/fail history, program version
- Added auto-import hooks to Sync-FromNAS-rsync.ps1 for Reports and STAGE folders

### Sync Script Updates (Sync-FromNAS-rsync.ps1)
- Added STAGE folder sync (NAS STAGE -> AD2)
- Added $syncedReportFiles and $syncedStageFiles tracking
- Added WO report auto-import after sync
- Added STAGE TXT auto-import after sync
- Updated status file with WO and STAGE counts

### Dataforth Audit Document
- Generated C:\Users\sysadmin\Desktop\Dataforth-Audit-2026-04-02.txt
- 22 sections: company info, network, AD computers/users/groups, GPO, DNS, shares, tasks, services, firewall, credentials, M365, security incidents, manufacturing infrastructure, pipeline, applications, backups, known issues, contacts

### PostgreSQL Migration (IN PROGRESS)
- Plan approved: PostgreSQL 18 on AD2, clean cutover
- PostgreSQL 18.3 installed via Chocolatey
- Database cluster initialized (C:\Program Files\PostgreSQL\18\data\)
- Service registered as postgresql-18 (runs as INTRANET\sysadmin)
- Database created: testdatadb owned by testdatadb_app
- SQL Server Express 2022 uninstalled

### SQLite Issues Documented
- Database grown to 4.4GB
- Single search query took 5,157 seconds (85 minutes)
- Stats query took 216 seconds
- WAL file grew to 454MB
- ANALYZE ran for 30+ minutes without completing
- SHM/WAL permission conflicts between SYSTEM and sysadmin

### Service Account (from previous session, still relevant)
- INTRANET\svc_testdatadb created in OU=ServiceAccounts
- testdatadb Windows service runs under this account
- SeServiceLogonRight granted

## Pending / Next Steps

   - Create database abstraction layer (db.js)
   - Migrate routes/api.js to async
   - Migrate import/export scripts
   - Build data migration script
   - Migrate 2.28M records
   - Test and cutover

2. **Tune PostgreSQL config:**
   - shared_buffers=1GB, work_mem=64MB, maintenance_work_mem=256MB

3. **MSSQL cleanup:**
   - May need reboot to fully remove SQL Server services

4. **Website upload:**
   - Old ASP.NET endpoints still dead (404)
