Add AD1 session data, memory entries for datasheet pipeline and security incident

- Imported AD1 Claude session files to clients/dataforth/session-logs/
- Created memory: project_datasheet_pipeline.md (full pipeline architecture)
- Created memory: project_dataforth_incident_2026-03-27.md (security incident + MFA)
- Updated MEMORY.md index
- Updated session log with AD1 pipeline rebuild findings

+# 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
