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

+### AD1 Claude Instance Results (same day)
+A Claude instance running on AD1/AD2 rebuilt the entire pipeline:
+- **Spec Parser built** (parsers/spec-reader.js) - reads 8 binary spec DATs, 1470 models
+- **Exact-match TXT formatter** (templates/datasheet-exact.js) - reverse-engineered from QB source
+- **Auto-export system** (database/export-datasheets.js) - generates TXT to X:\For_Web after import
+- **72 of 73 Quatronix datasheets generated** - in ComputerGuruConnectv2/Files/Quatronix-Datasheets.zip
+- **1.4M records reconciled** with existing For_Web files, 500K archived to year subfolders
+- **Root cause: CTONWTXT.BAT not called** in AUTOEXEC v4.1 since 2026-03-12. TXT piling up in C:\STAGE since Sept 2025.
+- **New pipeline eliminates** CTONWTXT.BAT, DFWDS.exe, and TestDataSheetUploader
+- **1 missing datasheet**: 177000-15 (SCM5B49-05) needs empty spec file from John Lehman
+- **Website upload still broken**: old ASP.NET endpoints return 404, need replacement
+- **7B series**: ~830K records need 7B-specific formatter (specs loaded but layout not implemented)
+- All session files saved to clients/dataforth/session-logs/ (from ClaudeSession-2026-03-27.zip)
+
 ### Next Steps for Datasheets
-- Need to build export mechanism to generate TXT datasheets from database records
-- TXT format matches the H8601-6.TXT sample (standard Dataforth test data sheet format)
-- Files need to land in C:\Shares\webshare\Test_Datasheets on AD2
-- Then need mechanism to get them to the website (either fix TestDataSheetUploader or replace it)
+- Website upload replacement (old endpoints dead, need new mechanism)
+- Fix CTONWTXT.BAT in AUTOEXEC or accept server-side generation as sufficient
+- 7B datasheet formatting
+- SCM5B49 spec file from John
+- New product lines: MAQ20/PWRM (XLS), 10D (JSON, ~May 2026)
