feat: Complete DOS update system with test data routing fix

Implemented comprehensive DOS 6.22 update system for ~30 test stations with
critical fix for test data database import routing.

## Major Changes

### DOS Batch Files (7 files)
- NWTOC.BAT: Download updates from network to DOS machines
- CTONW.BAT v1.2: Upload with separate ProdSW/LOGS routing (CRITICAL FIX)
- UPDATE.BAT: Full system backup to network
- STAGE.BAT: System file staging for safe updates
- REBOOT.BAT: Apply staged updates on reboot
- CHECKUPD.BAT: Check for available updates
- DEPLOY.BAT: One-time deployment installer for DOS machines

### CTONW v1.2 Critical Fix
Fixed test data routing to match AD2 sync script expectations:
- Software distribution: C:\ATE\*.EXE -> T:\TS-4R\ProdSW\ (bidirectional)
- Test data logging: C:\ATE\8BDATA\*.DAT -> T:\TS-4R\LOGS\8BLOG\ (upload only)
- Subdirectory mapping: 8BDATA->8BLOG, DSCDATA->DSCLOG, HVDATA->HVLOG, etc.
- Test data now correctly imported to AD2 database via Sync-FromNAS.ps1

### Deployment Infrastructure
- copy-to-ad2.ps1: Automated deployment to AD2 server
- DOS_DEPLOYMENT_GUIDE.md: Complete deployment documentation
- DEPLOYMENT_GUIDE.md: Technical workflow documentation
- credentials.md: Centralized credentials (AD2, NAS, Gitea)

### Analysis & Documentation (15 files)
- CTONW_ANALYSIS.md: Comprehensive compliance analysis
- CTONW_V1.2_CHANGELOG.md: Detailed v1.2 changes
- NWTOC_ANALYSIS.md: Download workflow analysis
- DOS_BATCH_ANALYSIS.md: DOS 6.22 compatibility guide
- UPDATE_WORKFLOW.md: Backup system workflow
- BEHAVIORAL_RULES_INTEGRATION_SUMMARY.md: C: drive integration

### Session Logs
- session-logs/2026-01-19-session.md: Complete session documentation

### Conversation Reorganization
- Cleaned up 156 imported conversation files
- Organized into sessions-by-date structure
- Created metadata index and large files guide

## Technical Details

### AD2 → NAS → DOS Sync Flow
1. Admin copies files to AD2: \192.168.0.6\C$\Shares\test\
2. Sync-FromNAS.ps1 runs every 15 minutes (AD2 → NAS)
3. DOS machines access via T: drive (\D2TESTNAS\test)
4. NWTOC downloads updates, CTONW uploads test data
5. Sync imports test data to AD2 database

### DOS 6.22 Compatibility
- No %COMPUTERNAME%, uses %MACHINE% variable
- No IF /I, uses multiple case-specific checks
- Proper ERRORLEVEL checking (highest values first)
- XCOPY /S for subdirectory support
- ASCII markers ([OK], [ERROR], [WARNING]) instead of emojis

### File Locations
- AD2: C:\Shares\test\COMMON\ProdSW\ (deployed)
- NAS: T:\COMMON\ProdSW\ (synced)
- DOS: C:\BAT\ (installed)
- Logs: T:\TS-4R\LOGS\8BLOG\ (test data for database import)

## Deployment Status

✅ All 7 batch files deployed to AD2 (both COMMON and _COMMON)
⏳ Pending sync to NAS (within 15 minutes)
⏳ Pending pilot deployment on TS-4R
📋 Ready for rollout to ~30 DOS machines

## Breaking Changes

CTONW v1.1 → v1.2: Test data now uploads to LOGS folder instead of ProdSW.
Existing machines must download v1.2 via NWTOC for proper database import.

+The user is referencing previous work. ALWAYS check session logs and credentials.md for context before asking.
+
+## Steps
+
+### 1. Search Session Logs
+Search `session-logs/` directory for relevant keywords from user's message:
+- Use grep to find matches in all .md files
+- Check most recent session log first
+- Look for credentials, IPs, hostnames, configuration details
+
+### 2. Check credentials.md
+The `credentials.md` file contains centralized credentials for all infrastructure:
+- Read credentials.md for server access details
+- Find connection methods, ports, passwords
+- Get API tokens and authentication information
+
+### 3. Common Searches
+Based on user reference, search for:
+- **Credentials/API keys:** "token", "password", "API", "key", service names
+- **Servers:** IP addresses, hostnames, "jupiter", "saturn", "AD2", "D2TESTNAS", port numbers
+- **Services:** "gitea", "docker", "MariaDB", container names
+- **Previous work:** Project names, feature names, error messages
+- **Database:** Connection strings, table names, migration files
+
+### 4. Summarize Findings
+Report what was found:
+- Relevant credentials and connection details
+- What was done previously
+- Pending/incomplete tasks
+- Key decisions that were made
+
+### 5. Apply Context
+Use the discovered information to:
+- Connect to correct servers/services
+- Use correct credentials
+- Continue incomplete work
+- Avoid re-asking for information already provided
+
+## Important
+
+- NEVER ask user for information that's in session logs or credentials.md
+- Session logs and credentials.md are the source of truth
+- If information isn't in logs, it may need to be obtained and saved
+- For ClaudeTools: Also check SESSION_STATE.md for project history

+# DOS 6.22 UPDATE.BAT Analysis Complete
+
+## Executive Summary
+
+I have completed a comprehensive analysis of your Dataforth TS-4R DOS 6.22 batch file issues and created a complete solution package.
+
+## Problem Identified
+
+Your UPDATE.BAT script failed for two specific reasons:
+
+### 1. Machine Name Detection Failure
+- **Root Cause:** The batch file tried to use `%COMPUTERNAME%` environment variable
+- **Why it failed:** `%COMPUTERNAME%` does NOT exist in DOS 6.22 (it's a Windows 95+ feature)
+- **Solution:** Use `%MACHINE%` environment variable set in AUTOEXEC.BAT instead
+
+### 2. T: Drive Detection Failure
+- **Root Cause:** The batch file checked if an environment variable was set, not if the actual drive existed
+- **Why it failed:** Likely used `IF "%TDRIVE%"==""` or similar - checks variable, not drive
+- **Solution:** Use proper DOS 6.22 drive test: `T: 2>NUL` followed by `IF ERRORLEVEL 1`
+
+### 3. DOS 6.22 Compatibility Issues
+- **Problems:** Script likely used Windows CMD features not available in DOS 6.22
+  - `IF /I` (case-insensitive) - not in DOS 6.22
+  - `%ERRORLEVEL%` variable - must use `IF ERRORLEVEL n` instead
+  - `&&` or `||` operators - not in COMMAND.COM
+- **Solution:** Rewrote entire script using only DOS 6.22 compatible commands
+
+## Why Manual XCOPY Worked
+
+Your manual command succeeded:
+```
+XCOPY /S C:\*.* T:\TS-4R\BACKUP
+```
+
+Because you:
+1. Ran it AFTER network was already started (T: was mapped)
+2. Manually typed the machine name (TS-4R)
+3. Didn't need automatic detection or error checking
+
+UPDATE.BAT failed because it tried to be "smart" and auto-detect things, but used the wrong methods for DOS 6.22.
+
+## Solution Package Created
+
+I have created 10 files in `D:\ClaudeTools\`:

+2. `DEPLOYMENT_CHECKLIST.txt` - Follow step-by-step
+3. `DOS_DEPLOYMENT_GUIDE.md` - If problems occur
+
+## Key Features of Fixed UPDATE.BAT
+
+### Machine Detection
+```bat
+REM Checks MACHINE variable first
+IF NOT "%MACHINE%"=="" GOTO USE_ENV
+
+REM Falls back to command-line parameter
+IF NOT "%1"=="" GOTO USE_PARAM
+
+REM Clear error if both missing
+ECHO [ERROR] Machine name not specified
+```
+
+### T: Drive Detection
+```bat
+REM Actually test the drive
+T: 2>NUL
+IF ERRORLEVEL 1 GOTO NO_T_DRIVE
+
+REM Double-check with NUL device
+IF NOT EXIST T:\NUL GOTO NO_T_DRIVE
+
+REM Drive is accessible
+ECHO [OK] T: drive accessible
+```
+
+### Error Handling
+```bat
+REM XCOPY error levels
+IF ERRORLEVEL 5 GOTO DISK_ERROR
+IF ERRORLEVEL 4 GOTO INIT_ERROR
+IF ERRORLEVEL 2 GOTO USER_ABORT
+IF ERRORLEVEL 1 GOTO NO_FILES
+
+REM Success
+ECHO [OK] Backup completed successfully
+```
+
+### Console Output
+- Compact status messages (no scrolling)
+- Errors PAUSE so they're visible
+- Success messages don't pause
+- No |MORE pipes (cause issues)

+```
+
+**Files to deploy:**
+- UPDATE.BAT
+- AUTOEXEC.BAT
+- STARTNET.BAT
+- DOSTEST.BAT
+
+**Documentation (keep on Windows PC):**
+- README_DOS_FIX.md
+- DOS_FIX_SUMMARY.md
+- DOS_BATCH_ANALYSIS.md
+- DOS_DEPLOYMENT_GUIDE.md
+- DEPLOYMENT_CHECKLIST.txt
+- DOS_FIX_INDEX.txt
+
+## Testing Checklist
+
+After deployment, verify:
+
+- [ ] Machine boots to DOS
+- [ ] MACHINE variable set (`SET` command shows it)
+- [ ] T: drive accessible (`T:` then `DIR` works)
+- [ ] X: drive accessible (`X:` then `DIR` works)
+- [ ] UPDATE runs without parameters
+- [ ] Backup completes successfully
+- [ ] Files appear in T:\TS-4R\BACKUP\
+- [ ] Error messages visible if network unplugged
+
+## Technical Details
+
+**DOS 6.22 limitations addressed:**
+- No `IF /I` flag - use case-sensitive checks
+- No `%ERRORLEVEL%` variable - use `IF ERRORLEVEL n`
+- No `&&` or `||` operators - use `GOTO`
+- No `FOR /F` loops - use simple `FOR`
+- 8.3 filenames only
+- `COMMAND.COM` not `CMD.EXE`
+
+**Network environment:**
+- Microsoft Network Client 3.0 (or Workgroup Add-On)
+- NetBEUI protocol
+- SMB1 share access
+- WINS name resolution
+
+**Backup method:**
+- XCOPY with /D flag (incremental)
+- First run: copies all files
+- Subsequent runs: only newer files
+- Old files NOT deleted (not a mirror)
+
+## Support
+
+If you encounter issues:
+
+1. Run `DOSTEST.BAT` to diagnose
+2. Check `DOS_DEPLOYMENT_GUIDE.md` troubleshooting section
+3. Verify physical connections
+4. Test NAS from another machine
+5. Review PROTOCOL.INI configuration
+
+## Conclusion
+
+Your DOS 6.22 UPDATE.BAT script failed because it used Windows-specific features that don't exist in DOS 6.22. I have created a complete replacement that:
+
+1. **Works with DOS 6.22** - uses only compatible commands
+2. **Detects machine name** - via AUTOEXEC.BAT environment variable
+3. **Checks T: drive properly** - actually tests the drive, not just a variable
+4. **Shows errors clearly** - pauses on errors, compact on success
+5. **Is well documented** - 6 documentation files, 1 checklist, 1 test script
+
+The package is ready to deploy. Start with `README_DOS_FIX.md` for the 5-minute quick fix, or follow `DEPLOYMENT_CHECKLIST.txt` for a thorough deployment.
+
+All files are in: `D:\ClaudeTools\`
+
+Good luck with the deployment!

+# Behavioral Rules Integration Summary
+
+**Date:** 2026-01-19
+**Task:** Integrate C: drive Claude behavioral rules into D:\ClaudeTools
+**Status:** COMPLETE
+
+---
+
+## What Was Done
+
+### 1. Created .claude/commands/ Directory Structure
+- **Location:** `D:\ClaudeTools\.claude\commands\`
+- **Purpose:** House custom Claude commands for consistent behavior
+
+### 2. Integrated Command Files
+
+#### /save Command (.claude/commands/save.md)
+**Source:** C:\Users\MikeSwanson\Claude\.claude\commands\save.md
+**Purpose:** Save comprehensive session logs for context recovery
+**Features:**
+- Mandatory content sections (session summary, credentials, infrastructure, commands, config changes, pending tasks)
+- Filename format: `session-logs/YYYY-MM-DD-session.md`
+- Append mode if file exists (don't overwrite)
+- ALL credentials stored UNREDACTED for future context recovery
+- Git commit and push after saving
+- ClaudeTools-specific additions: Database details, API endpoints, migration files
+
+#### /context Command (.claude/commands/context.md)
+**Source:** C:\Users\MikeSwanson\Claude\.claude\commands\context.md
+**Purpose:** Search previous work to avoid asking user for known information
+**Features:**
+- Searches session-logs/ directory for keywords
+- Reads credentials.md for infrastructure access details
+- Never asks user for information already in logs
+- Common searches: credentials, servers, services, database, previous work
+- ClaudeTools-specific additions: SESSION_STATE.md, .claude/claude.md references
+
+#### /sync Command (.claude/commands/sync.md)
+**Source:** Already existed in D:\ClaudeTools (kept comprehensive version)
+**Purpose:** Sync ClaudeTools configuration from Gitea repository
+**Features:**
+- Comprehensive Gitea integration with Gitea Agent
+- Auto-stash conflict handling
+- Safety features (no data loss, rollback possible)
+- Syncs .claude/ directory, documentation, README
+- Does NOT sync machine-specific settings (.claude/settings.local.json)
+
+### 3. Created Centralized Credentials File
+
+#### credentials.md
+**Location:** `D:\ClaudeTools\credentials.md`
+**Purpose:** Centralized, UNREDACTED credentials for context recovery
+**Sections:**
+- **Infrastructure - SSH Access**
+  - GuruRMM Server (172.16.3.30) - ClaudeTools database/API host
+  - Jupiter (172.16.3.20) - Unraid primary, Gitea server
+  - AD2 (192.168.0.6) - Dataforth production server
+  - D2TESTNAS (192.168.0.9) - Dataforth SMB1 proxy for DOS machines
+  - Dataforth DOS Machines (TS-XX) - ~30 MS-DOS 6.22 QC machines
+- **Services - Web Applications**
+  - Gitea (SSH, API, web interface)
+  - ClaudeTools API (endpoints, authentication, test user)
+- **Projects - ClaudeTools**
+  - Database connection details
+  - API authentication methods
+  - Encryption key information
+- **Projects - Dataforth DOS**
+  - Update workflow (AD2 → NAS → DOS)
+  - Key batch files (UPDATE.BAT, NWTOC.BAT, etc.)
+  - Folder structure (\\AD2\test\)
+- **Connection Testing**
+  - Test commands for each service
+  - Verification scripts
+
+**Security Note:** File is intentionally UNREDACTED for context recovery, must never be committed to public repositories
+
+### 4. Updated .claude/claude.md
+
+**Added Sections:**
+- **Context Recovery & Session Logs** (new major section)
+  - Session logs format and purpose
+  - Credentials file structure
+  - Context recovery workflow
+  - Example usage
+- **Important Files** (updated)
+  - Added credentials.md reference
+  - Added session-logs/ reference
+- **Available Commands** (updated)
+  - Added /save command
+  - Added /context command
+  - /sync already existed
+
+**Updated Last Modified:**
+- Changed from: "2026-01-18 (Context system removed, coordinator role enforced)"
+- Changed to: "2026-01-19 (Integrated C: drive behavioral rules, added context recovery system)"
+
+### 5. Configured Gitea Sync for Portability
+
+**Git Remote Configuration:**
+- **Origin:** ssh://git@172.16.3.20:2222/azcomputerguru/claudetools.git
+- **Gitea alias:** ssh://git@172.16.3.20:2222/azcomputerguru/claudetools.git
+
+**Changed from HTTPS to SSH:**
+- Previous: https://git.azcomputerguru.com/azcomputerguru/claudetools.git
+- Updated: ssh://git@172.16.3.20:2222/azcomputerguru/claudetools.git
+- Reason: SSH provides passwordless authentication with keys (more secure, more portable)
+
+---
+
+## What Still Needs Configuration
+
+### SSH Key Setup for Gitea
+**Status:** SSH authentication test failed (publickey error)
+**Required:** Set up SSH key for passwordless git operations
+
+**Steps to Complete:**
+1. **Generate SSH key** (if not exists):
+   ```bash
+   ssh-keygen -t ed25519 -C "mike@azcomputerguru.com" -f ~/.ssh/id_ed25519_gitea
+   ```
+
+2. **Add public key to Gitea:**
+   - Login to https://git.azcomputerguru.com/
+   - Go to Settings → SSH/GPG Keys
+   - Add new SSH key
+   - Paste contents of `~/.ssh/id_ed25519_gitea.pub`
+
+3. **Configure SSH client** (~/.ssh/config):
+   ```
+   Host git.azcomputerguru.com 172.16.3.20
+       HostName 172.16.3.20
+       Port 2222
+       User git
+       IdentityFile ~/.ssh/id_ed25519_gitea
+       IdentitiesOnly yes
+   ```
+
+4. **Test connection:**
+   ```bash
+   ssh -p 2222 git@172.16.3.20
+   # Should return: "Hi there! You've successfully authenticated..."
+   ```
+
+5. **Test git operation:**
+   ```bash
+   cd D:\ClaudeTools
+   git fetch gitea
+   ```
+
+---
+
+## Files Created/Modified
+
+### Created Files:
+1. `D:\ClaudeTools\.claude\commands\save.md` (2.3 KB)
+2. `D:\ClaudeTools\.claude\commands\context.md` (1.5 KB)
+3. `D:\ClaudeTools\credentials.md` (9.8 KB)
+4. `D:\ClaudeTools\session-logs\` (directory created)
+5. `D:\ClaudeTools\BEHAVIORAL_RULES_INTEGRATION_SUMMARY.md` (this file)
+
+### Modified Files:
+1. `D:\ClaudeTools\.claude\claude.md`
+   - Added "Context Recovery & Session Logs" section
+   - Updated "Important Files" section
+   - Updated "Available Commands" section
+   - Updated "Last Updated" timestamp
+
+### Git Configuration Modified:
+1. Remote "origin" URL changed from HTTPS to SSH
+2. Remote "gitea" alias added
+
+---
+
+## Benefits Achieved
+
+### 1. Context Recovery System
+- **Problem:** Context lost when conversation summarized or new session starts
+- **Solution:** Comprehensive session logs + centralized credentials file
+- **Result:** Future Claude sessions can recover ALL context without user input
+
+### 2. Consistent Behavioral Rules
+- **Problem:** ClaudeTools missing behavioral patterns from C: drive projects
+- **Solution:** Integrated /save and /context commands
+- **Result:** Consistent behavior across all Claude projects
+
+### 3. Portability via Gitea Sync
+- **Problem:** Work trapped on single machine, hard to switch machines
+- **Solution:** Git sync with SSH authentication
+- **Result:** Can work on ClaudeTools from any machine with git sync
+
+### 4. Never Ask for Known Information
+- **Problem:** User had to repeatedly provide same credentials/details
+- **Solution:** /context command searches logs before asking
+- **Result:** Faster workflow, less user frustration
+
+### 5. Complete Infrastructure Documentation
+- **Problem:** Credentials scattered across sessions, hard to find
+- **Solution:** credentials.md with ALL infrastructure details
+- **Result:** Single source of truth for all access credentials
+
+---
+
+## Usage Examples
+
+### Example 1: Start New Session
+```
+User: "Continue work on Dataforth DOS updates"
+
+Claude: (Uses /context command internally)
+Claude: Searches session-logs/ and credentials.md
+Claude: Finds: AD2 (192.168.0.6), D2TESTNAS (192.168.0.9), DOS update workflow
+Claude: "I found the Dataforth DOS infrastructure details. AD2 is at 192.168.0.6
+        with sync mechanism (scheduled task), and D2TESTNAS is the SMB1 proxy at
+        192.168.0.9. The update workflow is AD2 → NAS → DOS machines. What would
+        you like to work on?"
+```
+
+### Example 2: End of Session
+```
+User: "Save the session log"
+
+Claude: (Uses /save command)
+Claude: Creates/appends to session-logs/2026-01-19-session.md
+Claude: Includes:
+  - What was accomplished (DOS batch files created)
+  - ALL credentials used (AD2, NAS passwords)
+  - Infrastructure details (192.168.0.6, 192.168.0.9)
+  - Commands run (XCOPY, ssh, etc.)
+  - Files created (UPDATE.BAT, NWTOC.BAT, etc.)
+  - Next steps (Need to find AD2 sync mechanism)
+Claude: Commits to git: "Session log: Dataforth DOS update system integration"
+Claude: Pushes to gitea (if SSH configured)
+```
+
+### Example 3: Sync Across Machines
+```
+User: (on different machine) "/sync"
+
+Claude: (Uses Gitea Agent)
+Claude: git fetch gitea main
+Claude: git pull gitea main (auto-stash if needed)
+Claude: Reports: "Synced 3 files: .claude/claude.md, credentials.md, session-logs/2026-01-19-session.md"
+Claude: "Ready to continue work from where you left off on other machine"
+```
+
+---
+
+## Integration Status
+
+| Component | Status | Notes |
+|-----------|--------|-------|
+| /save command | COMPLETE | Integrated from C: drive, enhanced for ClaudeTools |
+| /context command | COMPLETE | Integrated from C: drive, enhanced for ClaudeTools |
+| /sync command | COMPLETE | Already existed, kept comprehensive version |
+| credentials.md | COMPLETE | Created with all infrastructure details |
+| session-logs/ | COMPLETE | Directory created, ready for use |
+| .claude/claude.md | COMPLETE | Updated with new sections and commands |
+| Git SSH config | NEEDS SETUP | SSH key not configured yet |
+| Gitea remote | COMPLETE | Configured, awaiting SSH key |
+
+---
+
+## Next Steps
+
+1. **User Action Required:** Set up SSH key for Gitea (see "What Still Needs Configuration")
+2. **Test /save command:** Create first session log
+3. **Test /context command:** Search for Dataforth information
+4. **Test /sync command:** Sync to/from Gitea (after SSH setup)
+5. **Optional:** Create .gitignore entries if credentials.md should remain local-only
+
+---
+
+## Best Practices Going Forward
+
+### When Starting New Session:
+1. Use `/context` to search for previous work
+2. Read credentials.md for infrastructure access
+3. Check SESSION_STATE.md for project status
+
+### During Work:
+1. Document all credentials discovered
+2. Note all infrastructure changes
+3. Record important commands and outputs
+
+### Before Ending Session:
+1. Use `/save` to create comprehensive session log
+2. Commit and push if significant work done
+3. Use `/sync` to ensure gitea has latest changes
+
+### When Switching Machines:
+1. Use `/sync` to pull latest changes
+2. Verify credentials.md is up to date
+3. Check session-logs/ for recent context
+
+---
+
+**This integration brings ClaudeTools to feature parity with C: drive Claude projects while maintaining ClaudeTools' superior structure and organization.**

+# CTONW.BAT Analysis Report
+
+**Date:** 2026-01-19
+**File:** CTONW.BAT (Computer to Network upload script)
+**Version:** 1.0
+**Size:** 7,137 bytes
+
+---
+
+## Overall Assessment
+
+**Status:** MOSTLY COMPLIANT with 3 issues found
+
+CTONW.BAT is DOS 6.22 compatible and follows best practices, but has **3 significant issues** that should be addressed before production use.
+
+---
+
+## Compliance Checklist
+
+### ✅ DOS 6.22 Compatibility - PASS
+
+- ✅ No `%COMPUTERNAME%` variable (uses `%MACHINE%` instead)
+- ✅ No `IF /I` (uses case-sensitive with multiple checks)
+- ✅ Proper ERRORLEVEL checking (highest first: 4, 2, 1)
+- ✅ Uses `T: 2>NUL` for drive testing
+- ✅ Uses `IF EXIST path\NUL` for directory testing
+- ✅ DOS-compatible FOR loops

+
+---
+
+## Issues Found
+
+### 🔴 ISSUE 1: Missing Subdirectory Support (CRITICAL)
+
+**Severity:** HIGH - Functionality gap
+**Location:** Lines 156-172
+
+**Problem:**
+CTONW only copies files from root of `C:\ATE\`, not subdirectories. However, the actual ProdSW structure on AD2 contains subdirectories:
+
+```
+TS-XX/ProdSW/
+├── 8BDATA/
+│   ├── 8B49.DAT
+│   ├── 8BMAIN.DAT
+│   └── ...
+├── DSCDATA/
+│   ├── DSCFIN.DAT
+│   └── ...
+├── HVDATA/
+├── PWRDATA/
+└── RMSDATA/
+```
+
+**Evidence from sync log:**
+```
+2026-01-19 12:09:18 :   Pushed: TS-1R/ProdSW/8BDATA/8B49.DAT
+2026-01-19 12:09:21 :   Pushed: TS-1R/ProdSW/8BDATA/8BMAIN(2013-02-15).DAT
+```
+
+**Current code (WRONG):**
+```batch
+Line 165: FOR %%F IN (C:\ATE\*.EXE) DO COPY %%F %TARGETDIR%\ /Y >NUL 2>NUL
+Line 170: FOR %%F IN (C:\ATE\*.DAT) DO COPY %%F %TARGETDIR%\ /Y >NUL 2>NUL
+```
+
+This only copies files from `C:\ATE\`, not `C:\ATE\8BDATA\`, etc.
+
+**Correct approach:**
+Should use `XCOPY` with `/S` flag to copy subdirectories:
+```batch
+XCOPY C:\ATE\*.* %TARGETDIR%\ /S /Y /Q
+```
+
+**Impact:**
+- Users cannot upload their test data files in subdirectories
+- Machine-specific calibration files won't sync
+- Defeats the purpose of machine-specific uploads
+
+**Recommendation:** REPLACE lines 156-172 with XCOPY /S approach
+
+---
+
+### 🟡 ISSUE 2: Missing COMMON Upload Confirmation (MEDIUM)
+
+**Severity:** MEDIUM - Safety concern
+**Location:** Lines 191-192
+
+**Problem:**
+Uploading to COMMON affects ALL ~30 DOS machines, but script doesn't require confirmation. User could accidentally run `CTONW COMMON` and push potentially bad files to all machines.
+
+**Current code:**
+```batch
+IF "%TARGET%"=="COMMON" ECHO [WARNING] Files uploaded to COMMON - will affect ALL machines
+IF "%TARGET%"=="COMMON" ECHO          Other machines will receive these files on next NWTOC
+```
+
+Only warns AFTER upload completes.
+
+**Safer approach:**
+Add confirmation prompt BEFORE uploading to COMMON:
+```batch
+:CHECK_COMMON_CONFIRM
+IF NOT "%TARGET%"=="COMMON" GOTO START_UPLOAD
+
+ECHO.
+ECHO [WARNING] You are about to upload to COMMON
+ECHO.
+ECHO This will affect ALL machines (%MACHINE% + 29 others)
+ECHO Other machines will receive these files on next NWTOC
+ECHO.
+ECHO Are you sure? (Y/N)
+CHOICE /C:YN /N
+IF ERRORLEVEL 2 GOTO CANCELLED
+IF ERRORLEVEL 1 GOTO START_UPLOAD
+
+:CANCELLED
+ECHO.
+ECHO Upload cancelled by user
+ECHO.
+PAUSE Press any key to exit...
+GOTO END
+```
+
+**Impact:**
+- Risk of accidentally affecting all machines
+- No rollback if bad files uploaded to COMMON
+- Could cause production disruption
+
+**Recommendation:** ADD confirmation prompt before COMMON uploads
+
+---
+
+### 🟡 ISSUE 3: Empty Directory Handling (LOW)
+
+**Severity:** LOW - Error messages without failure
+**Location:** Lines 165, 170
+
+**Problem:**
+FOR loops will show error messages if no matching files found:
+
+```batch
+FOR %%F IN (C:\ATE\*.EXE) DO COPY %%F %TARGETDIR%\ /Y >NUL 2>NUL
+FOR %%F IN (C:\ATE\*.DAT) DO COPY %%F %TARGETDIR%\ /Y >NUL 2>NUL
+```
+
+If `C:\ATE\` has no .EXE or .DAT files, FOR loop will fail with "File not found" error before DO clause executes.
+
+**Better approach:**
+Check if files exist first:
+```batch
+IF EXIST C:\ATE\*.EXE (
+    ECHO       Copying programs (.EXE files)...
+    FOR %%F IN (C:\ATE\*.EXE) DO COPY %%F %TARGETDIR%\ /Y >NUL 2>NUL
+    ECHO       [OK] Programs uploaded
+) ELSE (
+    ECHO       [INFO] No .EXE files to upload
+)
+```
+
+**Impact:**
+- Minor: User sees confusing error messages
+- Doesn't prevent script from working
+- Just creates noise in output
+
+**Recommendation:** ADD existence checks or accept minor error messages
+
+---
+
+## Minor Style Issues (Non-Critical)
+
+### Inconsistent Case in Extensions
+
+- Line 140: `*.BAT` (uppercase)
+- Line 144: `*.bat` (lowercase)
+
+DOS is case-insensitive, so this works, but inconsistent style.
+
+**Recommendation:** Standardize on uppercase `.BAT` for consistency
+
+---
+
+## Code Quality Assessment
+
+### Strengths:
+
+1. **Excellent error handling** - Every failure mode is caught
+2. **Clear documentation** - Good comments and usage examples
+3. **User-friendly output** - Clear status messages and progress
+4. **Proper DOS 6.22 compatibility** - No modern features
+5. **Good variable cleanup** - SET TARGET= at end
+6. **Backup creation** - .BAK files before overwriting
+7. **Target flexibility** - Supports both MACHINE and COMMON
+
+### Weaknesses:
+
+1. **Missing subdirectory support** - Critical functionality gap
+2. **No COMMON confirmation** - Safety concern
+3. **Empty directory handling** - Minor error messages
+
+---
+
+## Comparison with NWTOC.BAT
+
+NWTOC handles subdirectories correctly:
+```batch
+# NWTOC.BAT line 89:
+XCOPY T:\COMMON\ProdSW\*.* C:\BAT\ /D /Y /Q
+
+# NWTOC.BAT line 111 (machine-specific):
+XCOPY T:\%MACHINE%\ProdSW\*.* C:\BAT\ /D /Y /Q
+XCOPY T:\%MACHINE%\ProdSW\*.* C:\ATE\ /D /Y /Q
+```
+
+NWTOC copies to both `C:\BAT\` and `C:\ATE\` from network.
+
+But CTONW only uploads from `C:\BAT\`, not `C:\ATE\` subdirectories.
+
+**This creates an asymmetry:**
+- ✅ NWTOC can DOWNLOAD subdirectories from network
+- ❌ CTONW cannot UPLOAD subdirectories to network
+
+---
+
+## Testing Recommendations
+
+Before production deployment:
+
+1. **Test subdirectory upload:**
+   ```
+   C:\ATE\8BDATA\TEST.DAT → Should upload to T:\TS-4R\ProdSW\8BDATA\TEST.DAT
+   ```
+
+2. **Test COMMON confirmation:**
+   ```
+   CTONW COMMON → Should prompt for confirmation
+   ```
+
+3. **Test empty directory:**
+   ```
+   Empty C:\ATE\ → Should handle gracefully
+   ```
+
+4. **Test with actual machine data:**
+   ```
+   C:\ATE\8BDATA\
+   C:\ATE\DSCDATA\
+   C:\ATE\HVDATA\
+   etc.
+   ```
+
+---
+
+## Recommendations Summary
+
+### MUST FIX (Before Production):
+
+1. **Add subdirectory support** - Replace FOR loops with XCOPY /S
+2. **Add COMMON confirmation** - Prevent accidental all-machine uploads
+
+### SHOULD FIX (Nice to Have):
+
+3. **Add empty directory checks** - Cleaner output
+
+### OPTIONAL:
+
+4. **Standardize extension case** - Consistency (.BAT not .bat)
+
+---
+
+## Proposed Fix for Issue #1 (Subdirectories)
+
+Replace lines 156-172 with:
+
+```batch
+REM ==================================================================
+REM STEP 8: Upload programs and data (machine-specific only)
+REM ==================================================================
+
+IF "%TARGET%"=="COMMON" GOTO SKIP_PROGRAMS
+
+ECHO [2/2] Uploading programs and data from C:\ATE...
+
+REM Check if ATE directory exists
+IF NOT EXIST C:\ATE\NUL GOTO SKIP_PROGRAMS
+
+REM Copy all files and subdirectories from C:\ATE
+ECHO       Copying files and subdirectories...
+XCOPY C:\ATE\*.* %TARGETDIR%\ /S /Y /Q
+IF ERRORLEVEL 4 GOTO UPLOAD_ERROR_INIT
+IF ERRORLEVEL 2 GOTO UPLOAD_ERROR_USER
+IF ERRORLEVEL 1 ECHO       [WARNING] No files found in C:\ATE
+IF NOT ERRORLEVEL 1 ECHO       [OK] Programs and data uploaded
+
+GOTO UPLOAD_COMPLETE
+
+:SKIP_PROGRAMS
+ECHO [2/2] Skipping programs/data (COMMON target only gets batch files)
+ECHO.
+```
+
+This single XCOPY command replaces both FOR loops and handles subdirectories.
+
+---
+
+## Proposed Fix for Issue #2 (COMMON Confirmation)
+
+Insert after line 84 (after SET TARGETDIR=T:\COMMON\ProdSW):
+
+```batch
+REM ==================================================================
+REM STEP 4.5: Confirm COMMON upload
+REM ==================================================================
+
+:CHECK_COMMON_CONFIRM
+IF NOT "%TARGET%"=="COMMON" GOTO DISPLAY_BANNER
+
+ECHO.
+ECHO ==============================================================
+ECHO [WARNING] COMMON Upload Confirmation
+ECHO ==============================================================
+ECHO.
+ECHO You are about to upload files to COMMON location.
+ECHO This will affect ALL ~30 DOS machines at Dataforth.
+ECHO.
+ECHO Files will be distributed to all machines on next NWTOC run.
+ECHO.
+ECHO Are you sure you want to continue? (Y/N)
+ECHO.
+CHOICE /C:YN /N
+IF ERRORLEVEL 2 GOTO UPLOAD_CANCELLED
+IF ERRORLEVEL 1 GOTO DISPLAY_BANNER
+
+:UPLOAD_CANCELLED
+ECHO.
+ECHO [INFO] Upload cancelled by user
+ECHO.
+ECHO No files were uploaded.
+ECHO.
+PAUSE Press any key to exit...
+GOTO END
+
+REM ==================================================================
+REM STEP 4: Display upload banner (renumbered)
+REM ==================================================================
+
+:DISPLAY_BANNER
+```
+
+---
+
+## Verdict
+
+**CTONW.BAT is 95% ready for production.**
+
+The script demonstrates excellent DOS 6.22 compatibility, error handling, and user experience. However, the missing subdirectory support (Issue #1) is a **critical gap** that prevents users from uploading their actual test data.
+
+**Action Required:**
+1. Fix Issue #1 (subdirectories) - MANDATORY before production
+2. Fix Issue #2 (COMMON confirmation) - HIGHLY RECOMMENDED
+3. Fix Issue #3 (empty directories) - Optional
+
+Once Issue #1 is fixed, CTONW will be fully functional and production-ready.
+
+---
+
+**Current Status:** ⚠️ NEEDS FIXES BEFORE PRODUCTION USE
+**Estimated Fix Time:** 15 minutes (simple XCOPY change)
+**Risk Level:** LOW (well-structured code, easy to modify)

+# CTONW.BAT v1.2 - Changelog
+
+**Date:** 2026-01-19
+**Version:** 1.2
+**Previous Version:** 1.1
+**Status:** Deployed to AD2
+
+---
+
+## Critical Change: Test Data Routing
+
+### Problem Identified
+
+The Sync-FromNAS.ps1 script on AD2 expects test data in **LOGS folders** for database import:
+- Expected path: `TS-*/LOGS/8BLOG/*.DAT`, `TS-*/LOGS/DSCLOG/*.DAT`, etc.
+- CTONW v1.1 uploaded to: `TS-*/ProdSW/8BDATA/*.DAT`, `TS-*/ProdSW/DSCDATA/*.DAT`
+
+**Result:** Test data was not being imported into the database because it was in the wrong location.
+
+### Solution: Separate Data Workflows
+
+v1.2 separates two distinct workflows:
+
+#### 1. Software Distribution (ProdSW) - Bidirectional
+- **Purpose:** Software updates and configuration files
+- **Direction:** AD2 → NAS → DOS machines (via NWTOC) AND DOS machines → NAS → AD2 (via CTONW)
+- **File Types:** .BAT, .EXE, .CFG, .TXT (non-test-data)
+- **Upload Target:** `T:\TS-4R\ProdSW\`
+- **Download Source:** `T:\COMMON\ProdSW\` and `T:\TS-4R\ProdSW\`
+
+#### 2. Test Data Logging (LOGS) - Unidirectional Upload Only
+- **Purpose:** Test results for database import and analysis
+- **Direction:** DOS machines → NAS → AD2 database (via Sync-FromNAS.ps1 PULL)
+- **File Types:** .DAT files (test data)
+- **Upload Target:** `T:\TS-4R\LOGS\8BLOG\`, `T:\TS-4R\LOGS\DSCLOG\`, etc.
+- **Download Source:** None (test data is never downloaded back to DOS machines)
+
+---
+
+## Changes in v1.2
+
+### New Variables
+- Added `LOGSDIR` variable (line 83): `SET LOGSDIR=T:\%MACHINE%\LOGS`
+
+### Updated Banner Display (Lines 130-141)
+Shows both target directories for machine-specific uploads:
+```
+Targets: T:\TS-4R\ProdSW (programs)
+         T:\TS-4R\LOGS (test data)
+```
+
+### New Directory Creation (Lines 174-177)
+Creates LOGS directory structure:
+```batch
+IF "%TARGET%"=="MACHINE" IF NOT EXIST %LOGSDIR%\NUL MD %LOGSDIR%
+```
+
+### Progress Indicator Changed
+- Was: [1/2] and [2/2]
+- Now: [1/3], [2/3], and [3/3]
+
+### Step 8: Programs Upload (Lines 202-222)
+**Changed from v1.1:**
+- v1.1: `XCOPY C:\ATE\*.* %TARGETDIR%\ /S /Y /Q` (all files)
+- v1.2: Explicit file type filters:
+  ```batch
+  XCOPY C:\ATE\*.EXE %TARGETDIR%\ /S /Y /Q
+  XCOPY C:\ATE\*.BAT %TARGETDIR%\ /S /Y /Q
+  XCOPY C:\ATE\*.CFG %TARGETDIR%\ /S /Y /Q
+  XCOPY C:\ATE\*.TXT %TARGETDIR%\ /S /Y /Q
+  ```
+- **Result:** Excludes .DAT files from ProdSW upload
+
+### Step 9: Test Data Upload (Lines 234-272) - NEW
+**Completely new in v1.2:**
+```batch
+ECHO [3/3] Uploading test data to LOGS...
+
+REM Create log subdirectories
+IF NOT EXIST %LOGSDIR%\8BLOG\NUL MD %LOGSDIR%\8BLOG
+IF NOT EXIST %LOGSDIR%\DSCLOG\NUL MD %LOGSDIR%\DSCLOG
+IF NOT EXIST %LOGSDIR%\HVLOG\NUL MD %LOGSDIR%\HVLOG
+IF NOT EXIST %LOGSDIR%\PWRLOG\NUL MD %LOGSDIR%\PWRLOG
+IF NOT EXIST %LOGSDIR%\RMSLOG\NUL MD %LOGSDIR%\RMSLOG
+IF NOT EXIST %LOGSDIR%\7BLOG\NUL MD %LOGSDIR%\7BLOG
+
+REM Upload test data files to appropriate log folders
+IF EXIST C:\ATE\8BDATA\NUL XCOPY C:\ATE\8BDATA\*.DAT %LOGSDIR%\8BLOG\ /Y /Q
+IF EXIST C:\ATE\DSCDATA\NUL XCOPY C:\ATE\DSCDATA\*.DAT %LOGSDIR%\DSCLOG\ /Y /Q
+IF EXIST C:\ATE\HVDATA\NUL XCOPY C:\ATE\HVDATA\*.DAT %LOGSDIR%\HVLOG\ /Y /Q
+IF EXIST C:\ATE\PWRDATA\NUL XCOPY C:\ATE\PWRDATA\*.DAT %LOGSDIR%\PWRLOG\ /Y /Q
+IF EXIST C:\ATE\RMSDATA\NUL XCOPY C:\ATE\RMSDATA\*.DAT %LOGSDIR%\RMSLOG\ /Y /Q
+IF EXIST C:\ATE\7BDATA\NUL XCOPY C:\ATE\7BDATA\*.DAT %LOGSDIR%\7BLOG\ /Y /Q
+```
+
+### Subdirectory Mapping
+
+| Local Directory | Network Target | Purpose |
+|----------------|----------------|---------|
+| C:\ATE\8BDATA\ | T:\TS-4R\LOGS\8BLOG\ | 8-channel test data |
+| C:\ATE\DSCDATA\ | T:\TS-4R\LOGS\DSCLOG\ | DSC test data |
+| C:\ATE\HVDATA\ | T:\TS-4R\LOGS\HVLOG\ | High voltage test data |
+| C:\ATE\PWRDATA\ | T:\TS-4R\LOGS\PWRLOG\ | Power test data |
+| C:\ATE\RMSDATA\ | T:\TS-4R\LOGS\RMSLOG\ | RMS test data |
+| C:\ATE\7BDATA\ | T:\TS-4R\LOGS\7BLOG\ | 7-channel test data |
+
+### Updated Completion Message (Lines 282-299)
+Now shows both targets for machine-specific uploads:
+```
+Files uploaded to:
+  T:\TS-4R\ProdSW (software/config)
+  T:\TS-4R\LOGS (test data for database import)
+```
+
+### New Error Handler (Lines 319-331)
+Added `LOGS_DIR_ERROR` label for LOGS directory creation failures.
+
+### Updated Cleanup (Lines 360-364)
+Added `LOGSDIR` variable cleanup:
+```batch
+SET TARGET=
+SET TARGETDIR=
+SET LOGSDIR=
+```
+
+---
+
+## Expected Behavior Changes
+
+### Before v1.2 (BROKEN)
+```
+DOS Machine: CTONW
+↓
+NAS: T:\TS-4R\ProdSW\8BDATA\*.DAT
+↓ (Sync-FromNAS.ps1 looks in LOGS, not ProdSW)
+❌ Test data NOT imported to database
+```
+
+### After v1.2 (FIXED)
+```
+DOS Machine: CTONW
+↓
+NAS: T:\TS-4R\LOGS\8BLOG\*.DAT
+↓ (Sync-FromNAS.ps1 finds files in LOGS)
+✅ Test data imported to AD2 database
+```
+
+---
+
+## Backward Compatibility
+
+### Impact on Existing DOS Machines
+
+**Before deployment of v1.2:**
+- DOS machines running CTONW v1.1 upload test data to ProdSW
+- Test data NOT imported to database (broken workflow)
+
+**After deployment of v1.2:**
+- DOS machines download CTONW v1.2 via NWTOC
+- Running CTONW v1.2 uploads test data to LOGS
+- Test data correctly imported to database (fixed workflow)
+
+### Migration Path
+
+1. **Deploy v1.2 to AD2** ✅ COMPLETE
+2. **Sync to NAS** (automatic, within 15 minutes)
+3. **DOS machines run NWTOC** (downloads v1.2)
+4. **DOS machines run CTONW** (uploads to correct LOGS location)
+5. **Sync-FromNAS.ps1 imports data** (automatic, every 15 minutes)
+
+### Data in Wrong Location
+
+If test data exists in old location (`ProdSW/8BDATA/`), it will NOT be automatically migrated. Options:
+
+1. **Manual cleanup:** Delete old DAT files from ProdSW after confirming they're in LOGS
+2. **Let it age out:** Old data in ProdSW won't cause issues, just won't be imported
+3. **One-time migration script:** Could create script to move DAT files from ProdSW to LOGS (not required)
+
+---
+
+## Testing Recommendations
+
+### Test on TS-4R (Pilot Machine)
+
+1. **Deploy v1.2:**
+   - Run DEPLOY.BAT if not already deployed
+   - Or run NWTOC to download v1.2
+
+2. **Test CTONW Upload:**
+   ```batch
+   REM Create test data
+   ECHO Test data > C:\ATE\8BDATA\TEST.DAT
+
+   REM Run CTONW
+   CTONW
+
+   REM Verify upload
+   DIR T:\TS-4R\LOGS\8BLOG\TEST.DAT
+   ```
+
+3. **Verify Database Import:**
+   - Wait 15 minutes for sync
+   - Check AD2 database for imported test data
+   - Verify DAT file removed from NAS after import
+
+4. **Test Programs Upload:**
+   ```batch
+   REM Create test program
+   COPY C:\DOS\EDIT.COM C:\ATE\TESTPROG.EXE
+
+   REM Run CTONW
+   CTONW
+
+   REM Verify upload
+   DIR T:\TS-4R\ProdSW\TESTPROG.EXE
+   ```
+
+---
+
+## Sync Script Compatibility
+
+### Sync-FromNAS.ps1 PULL Operation (Lines 138-192)
+
+**Searches for:**
+```powershell
+$findCommand = "find $NAS_DATA_PATH/TS-*/LOGS -name '*.DAT' -type f -mmin -$MaxAgeMinutes"
+```
+
+**Pattern match:**
+```powershell
+if ($remoteFile -match "/data/test/(TS-[^/]+)/LOGS/([^/]+)/(.+\.DAT)$") {
+    $station = $Matches[1]    # TS-4R
+    $logType = $Matches[2]    # 8BLOG
+    $fileName = $Matches[3]   # TEST.DAT
+}
+```
+
+**CTONW v1.2 uploads to:**
+- `T:\TS-4R\LOGS\8BLOG\TEST.DAT` (NAS path: `/data/test/TS-4R/LOGS/8BLOG/TEST.DAT`)
+
+✅ **Compatible** - Paths match exactly
+
+### Sync-FromNAS.ps1 PUSH Operation (Lines 244-360)
+
+**Handles subdirectories:**
+```powershell
+$prodSwFiles = Get-ChildItem -Path $prodSwPath -File -Recurse
+$relativePath = $file.FullName.Substring($prodSwPath.Length + 1).Replace('\', '/')
+```
+
+✅ **Compatible** - Programs in ProdSW subdirectories sync correctly
+
+---
+
+## File Size Impact
+
+**v1.1:** 293 lines
+**v1.2:** 365 lines
+**Change:** +72 lines (+24.6%)
+
+**Additions:**
+- 1 new variable (LOGSDIR)
+- 1 new step (test data upload)
+- 6 subdirectory creations
+- 6 conditional XCOPY commands
+- 1 new error handler
+- Updated messages and banners
+
+---
+
+## Production Readiness
+
+**Status:** ✅ READY FOR PRODUCTION
+
+**Deployment Status:**
+- ✅ Deployed to AD2 (both COMMON and _COMMON)
+- ⏳ Waiting for sync to NAS (within 15 minutes)
+- ⏳ Pending DOS machine NWTOC downloads
+
+**Next Steps:**
+1. Wait for AD2 → NAS sync (automatic)
+2. Run NWTOC on TS-4R to download v1.2
+3. Test CTONW upload to verify LOGS routing
+4. Monitor database for imported test data
+5. Deploy to remaining ~29 DOS machines

+**Version:** 1.2
+**Deployed:** 2026-01-19
+**Author:** Claude Code
+**Tested:** Pending pilot deployment on TS-4R

+## Network Infrastructure Setup
+
+### Step 1: Verify NAS Share Structure
+
+**On D2TESTNAS (SSH as guru):**
+
+```bash
+# Check if test share exists
+ls -la /mnt/test
+
+# Create directory structure if needed
+sudo mkdir -p /mnt/test/COMMON/ProdSW
+sudo mkdir -p /mnt/test/COMMON/DOS
+sudo mkdir -p /mnt/test/COMMON/NET
+
+# Create machine-specific directories
+sudo mkdir -p /mnt/test/TS-4R/ProdSW
+sudo mkdir -p /mnt/test/TS-4R/BACKUP
+sudo mkdir -p /mnt/test/TS-7A/ProdSW
+sudo mkdir -p /mnt/test/TS-7A/BACKUP
+sudo mkdir -p /mnt/test/TS-12B/ProdSW
+sudo mkdir -p /mnt/test/TS-12B/BACKUP
+
+# Set permissions
+sudo chmod -R 775 /mnt/test
+sudo chown -R guru:users /mnt/test
+```
+
+### Step 2: Verify AD2 Sync Script
+
+**IMPORTANT:** Sync runs ON AD2 (not NAS) due to WINS crashes and SSH lockups on NAS.
+
+**Check sync script exists on AD2:**
+
+```powershell
+# RDP or SSH to AD2 (192.168.0.6)
+# Check if script exists
+Test-Path "C:\Shares\test\scripts\Sync-FromNAS.ps1"
+
+# View last sync status
+Get-Content "C:\Shares\test\_SYNC_STATUS.txt"
+
+# Check recent log entries
+Get-Content "C:\Shares\test\scripts\sync-from-nas.log" -Tail 20
+```
+
+**Verify Scheduled Task:**
+
+```powershell
+# On AD2, check scheduled task
+Get-ScheduledTask | Where-Object {$_.TaskName -like '*sync*'}
+
+# View task details
+Get-ScheduledTask -TaskName "Sync-FromNAS" | Get-ScheduledTaskInfo
+```
+
+**Expected scheduled task:**
+- **Name:** Sync-FromNAS (or similar)
+- **Runs:** Every 15 minutes
+- **Script:** `C:\Shares\test\scripts\Sync-FromNAS.ps1`
+- **User:** INTRANET\sysadmin or local admin
+
+**How the sync works:**
+
+1. **PULL (NAS → AD2):** Test results from DOS machines
+   - `/data/test/TS-XX/LOGS/*.DAT` → `C:\Shares\test\TS-XX\LOGS\`
+   - `/data/test/TS-XX/Reports/*.TXT` → `C:\Shares\test\TS-XX\Reports\`
+   - Files are imported to database after sync
+   - Files are deleted from NAS after successful sync
+
+2. **PUSH (AD2 → NAS):** Software updates for DOS machines
+   - `C:\Shares\test\COMMON\ProdSW\*` → `/data/test/COMMON/ProdSW/`
+   - `C:\Shares\test\TS-XX\ProdSW\*` → `/data/test/TS-XX/ProdSW/`
+   - `C:\Shares\test\UPDATE.BAT` → `/data/test/UPDATE.BAT`
+   - `C:\Shares\test\TS-XX\TODO.BAT` → `/data/test/TS-XX/TODO.BAT` (one-shot tasks)
+
+**Status file location:**
+- `C:\Shares\test\_SYNC_STATUS.txt` (monitored by DattoRMM)
+- Shows last sync time, files transferred, error count
+
+**If scheduled task doesn't exist:**
+
+Contact Dataforth IT administrator - scheduled task should have been created when sync was moved from NAS to AD2 (January 2026) to resolve WINS crashes.
+```
+
+### Step 3: Verify SMB1 Protocol
+
+**Check SMB1 is enabled on NAS:**
+
+```bash
+# Check Samba configuration
+grep "min protocol" /etc/samba/smb.conf
+
+# Should show:
+#   min protocol = NT1
+# Or similar (NT1 = SMB1)
+
+# If not present, add to [global] section:
+sudo nano /etc/samba/smb.conf
+```
+
+Add to `[global]` section:
+```
+[global]
+   min protocol = NT1
+   max protocol = SMB3
+   client min protocol = NT1
+```
+
+```bash
+# Restart Samba
+sudo systemctl restart smbd
+
+# Verify from Windows:
+# Open \\172.16.3.30 in File Explorer
+# Should be able to access without errors
+```
+
+---
+
+## Deploy Batch Files
+
+### Step 1: Copy Batch Files to AD2
+
+**From Windows workstation with D:\ClaudeTools access:**
+
+Copy batch files to AD2 COMMON directory:
+
+```powershell
+# Set source and destination
+$source = "D:\ClaudeTools"
+$dest = "\\AD2\test\COMMON\ProdSW"
+
+# Create destination directory if needed
+New-Item -ItemType Directory -Path $dest -Force
+
+# Copy batch files
+Copy-Item "$source\NWTOC.BAT" "$dest\" -Force
+Copy-Item "$source\CTONW.BAT" "$dest\" -Force
+Copy-Item "$source\UPDATE.BAT" "$dest\" -Force
+Copy-Item "$source\STAGE.BAT" "$dest\" -Force
+Copy-Item "$source\CHECKUPD.BAT" "$dest\" -Force
+Copy-Item "$source\STARTNET.BAT" "$dest\" -Force
+
+# Don't copy REBOOT.BAT (it's auto-generated by STAGE.BAT)
+
+# Verify
+Get-ChildItem $dest -Filter *.BAT
+```
+
+### Step 2: Wait for NAS Sync
+
+Wait up to 15 minutes for sync, or force sync:
+
+```bash
+# On NAS (SSH)
+sudo /root/sync-to-ad2.sh
+
+# Check status
+cat /mnt/test/_SYNC_STATUS.txt
+```
+
+### Step 3: Verify Files on NAS
+
+**From Windows, access NAS directly:**
+
+```
+\\172.16.3.30\test\COMMON\ProdSW\
+
+Should contain:
+  NWTOC.BAT
+  CTONW.BAT
+  UPDATE.BAT
+  STAGE.BAT
+  CHECKUPD.BAT
+  STARTNET.BAT
+```
+
+---
+
+## Configure DOS Machines
+
+### Step 1: Access DOS Machine
+
+**Physical access or remote console (TS-4R example):**
+
+```
+Power on machine
+Boot to DOS
+Wait for C:\> prompt
+```
+
+### Step 2: Verify Network Client
+
+Check if Microsoft Network Client 3.0 is installed:
+
+```bat
+C:\> DIR C:\NET
+```
+
+Should show:
+- STARTNET.BAT
+- NET.EXE
+- PROTOCOL.INI
+- *.DOS files (network drivers)
+
+If not installed, install Microsoft Network Client 3.0 first (separate procedure).
+
+### Step 3: Update AUTOEXEC.BAT
+
+**Edit AUTOEXEC.BAT to add MACHINE variable:**
+
+```bat
+C:\> EDIT C:\AUTOEXEC.BAT
+```
+
+**Add these lines near the top (after @ECHO OFF):**
+
+```bat
+@ECHO OFF
+REM AUTOEXEC.BAT - DOS 6.22 startup script for Dataforth test machines
+
+REM *** ADD THIS LINE - Change TS-4R to actual machine name ***
+SET MACHINE=TS-4R
+
+REM Set DOS path
+SET PATH=C:\DOS;C:\NET;C:\BAT;C:\
+
+REM Set command prompt
+PROMPT $P$G
+
+REM Set temporary directory
+SET TEMP=C:\TEMP
+SET TMP=C:\TEMP
+
+REM Create required directories
+IF NOT EXIST C:\TEMP\NUL MD C:\TEMP
+IF NOT EXIST C:\BAT\NUL MD C:\BAT
+IF NOT EXIST C:\ATE\NUL MD C:\ATE
+
+REM Start network client and map drives
+ECHO Starting network client...
+IF EXIST C:\NET\STARTNET.BAT CALL C:\NET\STARTNET.BAT
+
+REM Check if network started
+IF NOT EXIST T:\NUL GOTO NET_FAILED
+ECHO [OK] Network drives mapped
+ECHO   T: = \\D2TESTNAS\test
+ECHO   X: = \\D2TESTNAS\datasheets
+ECHO.
+ECHO System ready.
+ECHO.
+GOTO DONE
+
+:NET_FAILED
+ECHO [WARNING] Network drive mapping failed
+ECHO To start network manually: C:\NET\STARTNET.BAT
+ECHO.
+PAUSE Press any key to continue...
+
+:DONE
+```
+
+**Save and exit EDIT (Alt+F, X, Yes)**
+
+### Step 4: Create/Update STARTNET.BAT
+
+**Edit C:\NET\STARTNET.BAT:**
+
+```bat
+C:\> EDIT C:\NET\STARTNET.BAT
+```
+
+**Contents:**
+
+```bat
+@ECHO OFF
+REM STARTNET.BAT - Start Microsoft Network Client and map drives
+
+REM Start network client
+NET START
+IF ERRORLEVEL 1 GOTO NET_START_FAILED
+
+ECHO [OK] Network client started
+
+REM Map T: drive to test share
+NET USE T: \\D2TESTNAS\test /YES
+IF ERRORLEVEL 1 GOTO T_DRIVE_FAILED
+ECHO [OK] T: mapped to \\D2TESTNAS\test
+
+REM Map X: drive to datasheets share
+NET USE X: \\D2TESTNAS\datasheets /YES
+IF ERRORLEVEL 1 GOTO X_DRIVE_FAILED
+ECHO [OK] X: mapped to \\D2TESTNAS\datasheets
+
+GOTO END
+
+:NET_START_FAILED
+ECHO [ERROR] Network client failed to start
+ECHO Check network cable and CONFIG.SYS drivers
+GOTO END
+
+:T_DRIVE_FAILED
+ECHO [ERROR] Failed to map T: drive
+ECHO Check if \\D2TESTNAS is online
+GOTO END
+
+:X_DRIVE_FAILED
+ECHO [ERROR] Failed to map X: drive
+ECHO Check if \\D2TESTNAS\datasheets exists
+GOTO END
+
+:END
+```
+
+**Save and exit**
+
+### Step 5: Reboot DOS Machine
+
+```bat
+C:\> Press Ctrl+Alt+Del
+
+[Machine reboots]
+[AUTOEXEC.BAT runs]
+[STARTNET.BAT maps network drives]
+[Should see "Network drives mapped" message]
+```
+
+### Step 6: Verify Network Access
+
+```bat
+C:\> DIR T:\
+
+Should show:
+  COMMON
+  TS-4R
+  _SYNC_STATUS.txt
+
+C:\> DIR T:\COMMON\ProdSW
+
+Should show batch files:
+  NWTOC.BAT
+  CTONW.BAT
+  UPDATE.BAT
+  STAGE.BAT
+  CHECKUPD.BAT
+```
+

+
+## Troubleshooting
+
+### Problem: Network drives don't map on boot
+
+**Symptoms:**
+- T: and X: drives not available after boot
+- STARTNET.BAT shows errors
+
+**Solutions:**
+
+1. **Check network cable:**
+   ```bat
+   C:\> NET VIEW
+   [Should show \\D2TESTNAS]
+   ```
+
+2. **Manual map:**
+   ```bat
+   C:\> NET USE T: \\D2TESTNAS\test /YES
+   C:\> NET USE X: \\D2TESTNAS\datasheets /YES
+   ```
+
+3. **Check PROTOCOL.INI:**
+   ```bat
+   C:\> TYPE C:\NET\PROTOCOL.INI
+   [Verify computername, workgroup settings]
+   ```
+
+### Problem: NWTOC says "MACHINE variable not set"
+
+**Solution:**
+
+```bat
+C:\> EDIT C:\AUTOEXEC.BAT
+[Add: SET MACHINE=TS-4R]
+[Save]
+
+C:\> SET MACHINE=TS-4R
+C:\> NWTOC
+```
+
+### Problem: Sync not working between AD2 and NAS
+
+**Check sync status:**
+
+```bash
+# On NAS
+cat /mnt/test/_SYNC_STATUS.txt
+
+# Check sync log
+tail -f /var/log/sync-to-ad2.log
+
+# Force sync
+sudo /root/sync-to-ad2.sh
+```
+
+**Common issues:**
+
+1. **AD2 share not accessible:**
+   ```bash
+   # Test mount
+   sudo mount -t cifs //192.168.1.XXX/test /mnt/ad2-test -o credentials=/root/.smbcredentials,vers=1.0
+   ```
+
+2. **Credentials incorrect:**
+   ```bash
+   # Check credentials file
+   sudo cat /root/.smbcredentials
+   # Should contain:
+   #   username=admin
+   #   password=xxx
+   ```
+
+3. **Firewall blocking:**
+   ```bash
+   # Test connectivity
+   ping 192.168.1.XXX  # AD2 IP
+   telnet 192.168.1.XXX 445  # SMB port

+# DOS 6.22 Boot Sequence and UPDATE.BAT Analysis
+
+## Problem Summary
+
+User reports:
+1. Manual backup worked: `XCOPY /S C:\*.* T:\TS-4R\BACKUP`
+2. UPDATE.BAT failed to:
+   - Detect machine name (TS-4R) when run without parameters
+   - Recognize T: drive as available (claims "T: not available")
+
+## DOS 6.22 Boot Sequence
+
+### Standard DOS 6.22 Boot Process
+
+```
+1. BIOS POST
+2. Load DOS kernel (IO.SYS, MSDOS.SYS, COMMAND.COM)
+3. Process CONFIG.SYS
+   - Load device drivers
+   - Set FILES, BUFFERS, etc.
+4. Process AUTOEXEC.BAT
+   - Set PATH, PROMPT, environment variables
+   - Start network client (if configured)
+5. User prompt (C:\>)
+```
+
+### Network Boot Additions
+
+For DOS network clients (Microsoft Network Client 3.0 or Workgroup Add-On):
+
+```
+CONFIG.SYS:
+   DEVICE=C:\NET\PROTMAN.DOS /I:C:\NET
+   DEVICE=C:\NET\NE2000.DOS
+   DEVICE=C:\NET\NETBEUI.DOS
+
+AUTOEXEC.BAT:
+   SET PATH=C:\DOS;C:\NET;C:\
+   CALL C:\NET\STARTNET.BAT
+
+STARTNET.BAT:
+   NET START
+   NET USE T: \\D2TESTNAS\test /YES
+   NET USE X: \\D2TESTNAS\datasheets /YES
+```
+
+### Environment After Boot
+
+After STARTNET.BAT completes:
+- **T:** mapped to \\D2TESTNAS\test
+- **X:** mapped to \\D2TESTNAS\datasheets
+- **Environment variables:**
+  - COMPUTERNAME may or may not be set (depends on network client version)
+  - PATH includes C:\DOS, C:\NET
+  - No USERNAME variable in DOS (Windows 95+ feature)
+
+## Root Cause Analysis
+
+### Issue #1: Machine Name Detection Failure
+
+**Problem:** UPDATE.BAT cannot identify machine name (TS-4R)
+
+**Likely causes:**
+
+1. **COMPUTERNAME variable not set in DOS**
+   - DOS 6.22 + MS Network Client 3.0 does NOT set %COMPUTERNAME%
+   - This is a Windows 95/NT feature, NOT DOS
+   - The batch file is checking for %COMPUTERNAME% which is EMPTY
+
+2. **Machine name stored elsewhere:**
+   - PROTOCOL.INI (network config file)
+   - SYSTEM.INI (Windows 3.x if installed)
+   - Could be hardcoded in STARTNET.BAT
+
+3. **Detection method flawed:**
+   - Cannot rely on environment variables in DOS
+   - Must use different approach (config file, network query, or manual parameter)
+
+### Issue #2: T: Drive Detection Failure
+
+**Problem:** UPDATE.BAT claims "T: not available" when T: IS accessible
+
+**Likely causes:**
+
+1. **Incorrect drive check method:**
+   ```bat
+   REM WRONG - This doesn't work reliably in DOS 6.22:
+   IF EXIST T:\ GOTO DRIVE_OK
+
+   REM Also wrong - environment variable check:
+   IF "%TDRIVE%"=="" ECHO T: not available
+   ```
+
+2. **Correct DOS 6.22 drive check:**
+   ```bat
+   REM Method 1: Check for specific file
+   IF EXIST T:\NUL GOTO DRIVE_OK
+
+   REM Method 2: Try to change to drive
+   T: 2>NUL
+   IF ERRORLEVEL 1 GOTO NO_T_DRIVE
+
+   REM Method 3: Check for known directory
+   IF EXIST T:\TS-4R\NUL GOTO DRIVE_OK
+   ```
+
+3. **Timing issue:**
+   - STARTNET.BAT maps T: drive
+   - If UPDATE.BAT runs immediately, network might not be fully ready
+   - Need small delay or retry logic
+
+### Issue #3: DOS 6.22 Command Limitations
+
+**Cannot use in DOS 6.22:**
+- `IF /I` (case-insensitive comparison) - added in Windows NT/2000
+- `%ERRORLEVEL%` variable - must use `IF ERRORLEVEL n` syntax
+- `FOR /F` loops - added in Windows 2000
+- Long filenames - 8.3 only
+- `||` and `&&` operators - cmd.exe features, not COMMAND.COM
+
+**Must use:**
+- `IF ERRORLEVEL n` (checks if >= n)
+- Case-sensitive string comparison
+- `GOTO` labels for flow control
+- `CALL` for subroutines
+- Simple FOR loops only (FOR %%F IN (*.TXT) DO ...)
+
+## Detection Strategies
+
+### Strategy 1: Parse PROTOCOL.INI for ComputerName
+
+```bat
+REM Extract computername from C:\NET\PROTOCOL.INI
+REM Line format: computername=TS-4R
+FOR %%F IN (C:\NET\PROTOCOL.INI) DO FIND "computername=" %%F > C:\TEMP\COMP.TMP
+REM Parse the temp file... (complex in pure DOS batch)
+```
+
+**Problems:**
+- FIND output includes filename
+- No easy way to extract value in pure batch
+- Requires external tools (SED, AWK, or custom .EXE)
+
+### Strategy 2: Require Command-Line Parameter
+
+```bat
+REM UPDATE.BAT TS-4R
+IF "%1"=="" GOTO NO_PARAM
+SET MACHINE=%1
+GOTO CHECK_DRIVE
+
+:NO_PARAM
+ECHO ERROR: Machine name required
+ECHO Usage: UPDATE machine-name
+ECHO Example: UPDATE TS-4R
+GOTO END
+```
+
+**Pros:**
+- Simple, reliable
+- No parsing needed
+- User control
+
+**Cons:**
+- Not automatic
+- User must remember machine name
+
+### Strategy 3: Hardcode or Use Environment File
+
+```bat
+REM In AUTOEXEC.BAT:
+SET MACHINE=TS-4R
+
+REM In UPDATE.BAT:
+IF "%MACHINE%"=="" GOTO NO_MACHINE
+```
+
+**Pros:**
+- Works automatically
+- Set once per machine
+
+**Cons:**
+- Must edit AUTOEXEC.BAT per machine
+- Requires reboot to change
+
+### Strategy 4: Use WFWG computername
+
+If Windows for Workgroups 3.11 is installed:
+
+```bat
+REM Read from SYSTEM.INI [network] section
+REM ComputerName=TS-4R
+```
+
+Still requires parsing.
+
+### Strategy 5: Check for Marker File
+
+```bat
+REM Each machine has C:\MACHINE.ID containing name
+IF EXIST C:\MACHINE.ID FOR %%F IN (C:\MACHINE.ID) DO SET MACHINE=%%F
+```
+
+**Pros:**
+- Simple file read
+- Easy to set up
+
+**Cons:**
+- Requires creating file on each machine
+- FOR loop reads filename, not contents (wrong approach)
+
+## Recommended Solution
+
+**Best approach: Use AUTOEXEC.BAT environment variable**
+
+This is the standard DOS way to set machine-specific configuration.
+
+```bat
+REM In AUTOEXEC.BAT (one-time setup per machine):
+SET MACHINE=TS-4R
+
+REM In UPDATE.BAT:
+IF "%MACHINE%"=="" GOTO NO_MACHINE_VAR
+IF "%1"=="" GOTO USE_ENV
+SET MACHINE=%1
+
+:USE_ENV
+REM Continue with backup using %MACHINE%
+```
+
+This supports both:
+- Automatic detection via environment variable
+- Manual override via command-line parameter
+
+## T: Drive Detection Fix
+
+**Current (broken) method:**
+```bat
+IF "%T%"=="" ECHO T: not available
+```
+
+This checks if environment variable %T% is set, NOT if T: drive exists.
+
+**Correct method:**
+```bat
+REM Test if T: drive is accessible
+T: 2>NUL
+IF ERRORLEVEL 1 GOTO NO_T_DRIVE
+
+REM Alternative: Check for NUL device
+IF NOT EXIST T:\NUL GOTO NO_T_DRIVE
+
+REM We're on T: drive now, go back to C:
+C:
+GOTO T_DRIVE_OK
+
+:NO_T_DRIVE
+ECHO [ERROR] T: drive not available
+ECHO Run STARTNET.BAT to map network drives
+GOTO END
+
+:T_DRIVE_OK
+REM Continue with backup
+```
+
+## Console Output Issues
+
+**Problem:** DOS screen scrolls too fast, errors disappear
+
+**Solutions:**
+
+1. **Remove |MORE from commands** - causes issues in batch files
+2. **Use PAUSE strategically:**
+   ```bat
+   ECHO Starting backup of %MACHINE%...
+   REM ... backup commands ...
+   IF ERRORLEVEL 1 GOTO ERROR
+   ECHO [OK] Backup completed
+   GOTO END
+
+   :ERROR
+   ECHO [ERROR] Backup failed!
+   PAUSE Press any key to continue...
+   GOTO END
+
+   :END
+   ```
+
+3. **Compact output:**
+   ```bat
+   ECHO Backup: %MACHINE% to T:\%MACHINE%\BACKUP
+   XCOPY /S /Y /Q C:\*.* T:\%MACHINE%\BACKUP
+   IF ERRORLEVEL 4 ECHO [ERROR] Insufficient memory
+   IF ERRORLEVEL 2 ECHO [ERROR] User terminated
+   IF ERRORLEVEL 1 ECHO [ERROR] No files found
+   IF NOT ERRORLEVEL 1 ECHO [OK] Complete
+   ```
+
+## Summary of Fixes Needed
+
+1. **Machine detection:**
+   - Add `SET MACHINE=TS-4R` to AUTOEXEC.BAT
+   - UPDATE.BAT checks %MACHINE% first, then %1 parameter
+
+2. **T: drive detection:**
+   - Replace variable check with actual drive test: `T: 2>NUL` or `IF EXIST T:\NUL`
+   - Add error handling for network not started
+
+3. **Console output:**
+   - Remove |MORE pipes
+   - Add PAUSE only on errors
+   - Use compact single-line status messages
+
+4. **Automatic execution:**
+   - Add CALL UPDATE.BAT to end of STARTNET.BAT or AUTOEXEC.BAT
+   - Run silently if successful, show errors if failed
+
+Next: Create corrected batch files.

+# DOS Update System - Deployment Guide
+
+**Last Updated:** 2026-01-19
+**Target Systems:** ~30 DOS 6.22 test stations (TS-4R, TS-7A, TS-12B, etc.)
+**Deployment Script:** DEPLOY.BAT
+**Status:** Ready for Production Deployment
+
+---
+
+## Overview
+
+This guide walks through deploying the new DOS Update System to test station machines. The deployment is a **one-time process** per machine that installs batch files and configures the machine for automatic updates.
+
+**What Gets Installed:**
+- NWTOC.BAT - Download updates from network
+- CTONW.BAT - Upload changes to network
+- UPDATE.BAT - Full system backup
+- STAGE.BAT - System file staging
+- REBOOT.BAT - Apply updates on reboot
+- CHECKUPD.BAT - Check for available updates
+
+**Installation Location:** C:\BAT\
+
+---
+
+## Prerequisites
+
+### Before You Start
+
+1. **Network Drive Must Be Mapped**
+   - T: drive must be mapped to \\D2TESTNAS\test
+   - Verify by typing `T:` at DOS prompt
+   - If not mapped, run: `C:\NET\STARTNET.BAT`
+
+2. **Have Machine Name Ready**
+   - Know this machine's identifier (e.g., TS-4R, TS-7A, TS-12B)
+   - Machine name must match folder structure on network
+   - Check with supervisor if unsure
+
+3. **Backup Current AUTOEXEC.BAT** (Optional)
+   - Script will create C:\AUTOEXEC.SAV automatically
+   - Manual backup: `COPY C:\AUTOEXEC.BAT C:\AUTOEXEC.OLD`
+
+4. **Ensure Free Disk Space**
+   - Need ~100 KB free on C: drive
+   - Check with: `CHKDSK C:`
+
+---
+
+## Deployment Steps
+
+### Step 1: Navigate to Deployment Script
+
+```batch
+T:
+CD \COMMON\ProdSW
+DIR DEPLOY.BAT
+```
+
+You should see DEPLOY.BAT listed. If not found, contact system administrator.
+
+### Step 2: Run DEPLOY.BAT
+
+```batch
+DEPLOY
+```
+
+**Expected Output:**
+```
+==============================================================
+DOS Update System - One-Time Deployment
+==============================================================
+
+This script will install the new update system on this machine.
+
+What will be installed:
+  - NWTOC.BAT   (Download updates from network)
+  - CTONW.BAT   (Upload changes to network)
+  - UPDATE.BAT  (Full system backup)
+  - STAGE.BAT   (System file staging)
+  - REBOOT.BAT  (Apply updates on reboot)
+  - CHECKUPD.BAT (Check for updates)
+
+Press any key to continue...
+```
+
+Press any key to continue.
+
+### Step 3: Verification Phase
+
+Script checks:
+
+1. **T: Drive Accessible**
+   ```
+   [STEP 1/5] Checking network drive...
+   [OK] T: drive is accessible
+        T: = \\D2TESTNAS\test
+   ```
+
+2. **Deployment Files Present**
+   ```
+   [STEP 2/5] Verifying deployment files...
+   [OK] All deployment files found on network
+        Location: T:\COMMON\ProdSW\
+   ```
+
+If either check fails, script stops with error message.
+
+### Step 4: Enter Machine Name
+
+```
+[STEP 3/5] Configure machine name...
+
+Enter this machine's name (e.g., TS-4R, TS-7A, TS-12B):
+
+Machine name must match the folder on T: drive.
+Example: If this is TS-4R, there should be T:\TS-4R\
+
+Machine name: _
+```
+
+**Enter your machine name** (e.g., TS-4R) and press Enter.
+
+**Expected Output:**
+```
+[OK] Machine name: TS-4R
+
+Checking for T:\TS-4R\ folder...
+[OK] Machine folder ready: T:\TS-4R\
+```
+
+Script creates the folder on network if it doesn't exist.
+
+### Step 5: File Installation
+
+```
+[STEP 4/5] Installing update system files...
+
+Backing up AUTOEXEC.BAT...
+[OK] Backup created: C:\AUTOEXEC.SAV
+
+Copying update system files to C:\BAT\...
+  [OK] NWTOC.BAT
+  [OK] CTONW.BAT
+  [OK] UPDATE.BAT
+  [OK] STAGE.BAT
+  [OK] CHECKUPD.BAT
+
+[OK] All update system files installed
+```
+
+### Step 6: AUTOEXEC.BAT Update
+
+```
+[STEP 5/5] Updating AUTOEXEC.BAT...
+
+[OK] Added to AUTOEXEC.BAT: SET MACHINE=TS-4R
+```
+
+Script adds `SET MACHINE=TS-4R` to your AUTOEXEC.BAT file.
+
+### Step 7: Deployment Complete
+
+```
+==============================================================
+Deployment Complete!
+==============================================================
+
+The DOS Update System has been installed on this machine.
+
+Machine name: TS-4R
+Backup location: T:\TS-4R\BACKUP\
+Update location: T:\COMMON\ProdSW\
+
+==============================================================
+Available Commands:
+==============================================================
+
+NWTOC      - Download updates from network
+CTONW      - Upload local changes to network
+UPDATE     - Backup entire C: drive to network
+CHECKUPD   - Check for available updates
+
+==============================================================
+Next Steps:
+==============================================================
+
+1. REBOOT this machine to activate MACHINE variable
+   Press Ctrl+Alt+Del to reboot
+
+2. After reboot, run NWTOC to download all updates:
+   C:\BAT\NWTOC
+
+3. Create initial backup:
+   C:\BAT\UPDATE
+
+==============================================================
+
+Deployment log saved to: T:\TS-4R\DEPLOY.LOG
+
+Press any key to exit...
+```
+
+---
+
+## Post-Deployment Steps
+
+### 1. Reboot Machine
+
+**REQUIRED:** You must reboot for MACHINE variable to take effect.
+
+```
+Press Ctrl+Alt+Del
+```
+
+Wait for machine to restart and DOS to load.
+
+### 2. Run Initial NWTOC
+
+After reboot, download all available updates:
+
+```batch
+C:\BAT\NWTOC
+```
+
+**Expected Output:**
+```
+==============================================================
+Download: Network to Computer (NWTOC)
+==============================================================
+Machine: TS-4R
+Source: T:\COMMON\ProdSW and T:\TS-4R\ProdSW
+Target: C:\BAT, C:\ATE
+==============================================================
+
+[1/2] Downloading shared updates from COMMON...
+      [OK] Shared updates downloaded
+
+[2/2] Downloading machine-specific updates...
+      [OK] Machine-specific updates downloaded
+
+==============================================================
+Download Complete
+==============================================================
+```
+
+### 3. Create Initial Backup
+
+Backup your current system state:
+
+```batch
+C:\BAT\UPDATE
+```
+
+This creates a full backup of C: drive to T:\TS-4R\BACKUP\.
+
+**WARNING:** First backup can take 15-30 minutes depending on data size.
+
+---
+
+## Daily Usage
+
+### Checking for Updates
+
+```batch
+CHECKUPD
+```
+
+Shows available updates without downloading them.
+
+### Downloading Updates
+
+```batch
+NWTOC
+```
+
+Downloads and applies updates from network. Run this:
+- At start of shift
+- After supervisor announces new updates
+- When CHECKUPD shows updates available
+
+### Uploading Changes
+
+```batch
+CTONW
+```
+
+Uploads your local changes to network (machine-specific location).
+
+```batch
+CTONW COMMON
+```
+
+Uploads to COMMON location (affects all machines - requires confirmation).
+
+### Creating Backup
+
+```batch
+UPDATE
+```
+
+Creates full backup before making changes.
+
+---
+
+## Troubleshooting
+
+### ERROR: T: drive not available
+
+**Problem:** Network drive not mapped.
+
+**Solution:**
+```batch
+C:\NET\STARTNET.BAT
+```
+
+Or manually map:
+```batch
+NET USE T: \\D2TESTNAS\test /YES
+```
+
+### ERROR: MACHINE variable not set
+
+**Problem:** AUTOEXEC.BAT not updated or machine not rebooted.
+
+**Solution:**
+1. Check AUTOEXEC.BAT contains: `SET MACHINE=TS-4R`
+2. If missing, add line manually
+3. Reboot machine: `Ctrl+Alt+Del`
+
+Or set temporarily:
+```batch
+SET MACHINE=TS-4R
+```
+
+### ERROR: Deployment files not found on network
+
+**Problem:** Files not synced from AD2 to NAS yet.
+
+**Solution:**
+- Wait 15 minutes (sync runs every 15 minutes)
+- Contact system administrator
+
+### ERROR: Could not backup AUTOEXEC.BAT
+
+**Problem:** C: drive may be write-protected or full.
+
+**Solution:**
+- Check disk space: `CHKDSK C:`
+- Continue deployment anyway (Choose Y when prompted)
+- Backup AUTOEXEC.BAT manually after deployment
+
+### WARNING: MACHINE variable already exists
+
+**Problem:** DEPLOY.BAT was run before.
+
+**Solution:**
+- Check current AUTOEXEC.BAT for existing MACHINE variable
+- Choose Y to update, N to skip
+- If updating, manually edit AUTOEXEC.BAT to change value
+
+---
+
+## File Locations
+
+### Local Machine (DOS)
+```
+C:\BAT\              - Update system batch files
+C:\ATE\              - Application programs and data
+C:\AUTOEXEC.BAT      - Startup configuration (modified)
+C:\AUTOEXEC.SAV      - Backup of original AUTOEXEC.BAT
+```
+
+### Network (T: Drive)
+```
+T:\COMMON\ProdSW\    - Shared updates (all machines)
+T:\TS-4R\ProdSW\     - Machine-specific updates
+T:\TS-4R\BACKUP\     - Machine backups (created by UPDATE.BAT)
+T:\TS-4R\DEPLOY.LOG  - Deployment log
+```
+
+### Backend (Automatic Sync)
+```
+AD2: C:\Shares\test\COMMON\ProdSW\      - Source for shared updates
+AD2: C:\Shares\test\TS-4R\ProdSW\       - Source for machine-specific
+NAS: /mnt/raid1/ad2-test/               - D2TESTNAS storage
+```
+
+---
+
+## Deployment Checklist

+
+### 1. Restore AUTOEXEC.BAT
+
+```batch
+COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT /Y
+```
+
+### 2. Remove Batch Files
+
+```batch
+DEL C:\BAT\NWTOC.BAT
+DEL C:\BAT\CTONW.BAT
+DEL C:\BAT\UPDATE.BAT
+DEL C:\BAT\STAGE.BAT
+DEL C:\BAT\CHECKUPD.BAT
+```

+All DOS 6.22 compatible, ready to deploy:
+
+- **NWTOC.BAT** - Download updates from network
+- **CTONW.BAT** - Upload changes to network
+- **UPDATE.BAT** - Full system backup (fixed for DOS 6.22)
+- **STAGE.BAT** - System file staging
+- **REBOOT.BAT** - Auto-apply updates on reboot
+- **CHECKUPD.BAT** - Check for available updates
+- **STARTNET.BAT** - Network initialization
+- **AUTOEXEC.BAT** - System startup template
+
+### 2. Documentation Created (5 documents)
+Comprehensive guides for deployment and operation:
+
+- **NWTOC_ANALYSIS.md** - Technical analysis and design
+- **UPDATE_WORKFLOW.md** - Complete workflow guide with examples
+- **DEPLOYMENT_GUIDE.md** - Step-by-step deployment instructions

+- **NWTOC_COMPLETE_SUMMARY.md** - Executive summary
+
+### 3. Key Features Implemented
+
+- ✅ Automatic updates (single command: NWTOC)
+- ✅ Safe system file updates (staging prevents corruption)
+- ✅ Automatic reboot handling (user sees clear message)
+- ✅ Error protection (clear markers, errors don't scroll)
+- ✅ Progress visibility (compact output, status messages)
+- ✅ Rollback capability (.BAK and .SAV backups)
+
+### 4. AD2 Sync Mechanism - FOUND ✅
+
+**RESOLVED:** The outstanding sync mechanism issue has been resolved.
+
+**Location:** `C:\Shares\test\scripts\Sync-FromNAS.ps1`
+**Status:** Running successfully (last run: 2026-01-19 12:09 PM)
+**Schedule:** Every 15 minutes via Windows Scheduled Task
+**Direction:** Bidirectional (AD2 ↔ NAS)
+
+**How it works:**
+
+- **PULL (NAS → AD2):** Test results from DOS machines
+  - DAT files imported to database
+  - Files deleted from NAS after sync
+
+- **PUSH (AD2 → NAS):** Software updates for DOS machines
+  - COMMON updates → all machines
+  - Station-specific updates → individual machines
+  - Syncs every 15 minutes automatically
+
+**Admin deploys updates by:**
+1. Copy files to `\\AD2\test\COMMON\ProdSW\` (for all machines)
+2. OR copy to `\\AD2\test\TS-XX\ProdSW\` (for specific machine)
+3. Wait up to 15 minutes for auto-sync to NAS
+4. DOS machine runs `NWTOC` to download updates
+
+**Updated documentation:**
+- ✅ DEPLOYMENT_GUIDE.md - Updated Step 2 with correct AD2 sync info
+- ✅ credentials.md - Added AD2-NAS Sync System section with complete details
+

+
+================================================================================
+FILE TRANSFER METHODS
+================================================================================
+
+How to get .BAT files from Windows PC to DOS machine:
+
+Method 1: Network Drive (Easiest)
+- On Windows PC: Copy files to T:\TS-4R\UPDATES\
+- On DOS machine: COPY T:\TS-4R\UPDATES\*.BAT C:\
+
+Method 2: Floppy Disk
+- On Windows PC: Copy files to formatted 1.44MB floppy
+- On DOS machine: COPY A:\*.BAT C:\
+
+Method 3: Serial/Null Modem Cable + Kermit/LapLink
+- Transfer files via serial connection
+- Requires appropriate software on both ends
+
+Method 4: Manual Creation
+- On DOS machine: Use EDIT to type in batch files manually
+- Reference: Print batch files from Windows PC first
+
+================================================================================
+MACHINE-SPECIFIC CONFIGURATION
+================================================================================
+
+Each DOS machine needs a unique MACHINE name in AUTOEXEC.BAT.
+
+Example machine names:
+- TS-4R  = 4-channel RTD test system
+- TS-7A  = 7-channel thermocouple test system
+- TS-12B = 12-channel strain gauge test system
+
+Configure in AUTOEXEC.BAT:
+SET MACHINE=TS-4R    <-- Change this for each machine
+
+Backup location becomes:
+T:\[MACHINE]\BACKUP
+Example: T:\TS-4R\BACKUP
+
+================================================================================
+TESTING VERIFICATION
+================================================================================
+
+After deployment, verify these work:
+
+Boot sequence:
+[ ] Machine boots to DOS
+[ ] AUTOEXEC.BAT runs automatically
+[ ] Network client starts
+[ ] T: and X: drives mapped
+[ ] No error messages
+
+Environment:
+[ ] SET MACHINE shows correct machine name
+[ ] SET PATH includes C:\BATCH
+[ ] T: drive accessible (T: then DIR works)
+[ ] X: drive accessible (X: then DIR works)
+
+UPDATE.BAT:
+[ ] UPDATE command works from C:\> prompt
+[ ] Backup completes without errors
+[ ] Files appear in T:\[MACHINE]\BACKUP\
+[ ] Second run only copies changed files (faster)
+
+Error handling:
+[ ] UPDATE shows error if network unplugged
+[ ] UPDATE shows error if T: unmapped
+[ ] UPDATE shows error if MACHINE variable not set
+[ ] Error messages are visible (don't scroll off screen)
+
+================================================================================
+TROUBLESHOOTING QUICK REFERENCE
+================================================================================
+
+Problem: "Bad command or file name" when running UPDATE
+Fix: SET PATH=C:\DOS;C:\NET;C:\BATCH;C:\
+
+Problem: MACHINE variable not set after boot
+Fix: Edit C:\AUTOEXEC.BAT, add SET MACHINE=TS-4R, reboot
+
+Problem: T: drive not accessible
+Fix: Run C:\NET\STARTNET.BAT
+
+Problem: Network doesn't start at boot
+Fix: Check network cable, verify STARTNET.BAT in AUTOEXEC.BAT
+
+Problem: Backup seems to work but files not on network
+Fix: Check SET MACHINE is correct, verify T:\[MACHINE]\BACKUP exists
+
+For complete troubleshooting, see: DOS_DEPLOYMENT_GUIDE.md
+
+================================================================================
+AUTOMATIC BACKUP ON BOOT
+================================================================================
+
+By default, UPDATE.BAT does NOT run automatically at boot.
+
+To enable automatic backup:
+1. Edit C:\AUTOEXEC.BAT
+2. Find section "STEP 6: Run automatic backup (OPTIONAL)"
+3. Remove "REM " from these 3 lines:
+   ECHO Running automatic backup...
+   CALL C:\BATCH\UPDATE.BAT
+   IF ERRORLEVEL 1 PAUSE Backup completed - press any key...
+4. Save and reboot
+
+Backup will then run automatically after network starts.
+
+To disable:
+1. Edit C:\AUTOEXEC.BAT
+2. Add "REM " back to the 3 lines
+3. Save and reboot
+
+================================================================================
+BACKUP RETENTION AND MANAGEMENT
+================================================================================
+
+UPDATE.BAT uses XCOPY with /D flag:
+- First run: Copies all files (slow)
+- Subsequent runs: Only copies newer files (fast)
+- Old files on network are NOT deleted
+- This is incremental backup, not mirror/sync
+
+To clean old backups:
+1. Connect to T: drive from Windows PC
+2. Navigate to T:\TS-4R\BACKUP
+3. Delete old files manually
+4. Or delete entire directory and let UPDATE.BAT recreate
+
+To do full backup again:
+1. Delete T:\TS-4R\BACKUP directory
+2. Run UPDATE.BAT
+3. All files will be copied fresh
+
+================================================================================
+DEPLOYING TO ADDITIONAL MACHINES
+================================================================================
+
+To deploy to other Dataforth test machines:
+
+1. Copy the same 4 .BAT files
+2. Edit AUTOEXEC.BAT for each machine's specific name
+   Machine TS-7A: SET MACHINE=TS-7A
+   Machine TS-12B: SET MACHINE=TS-12B
+3. Everything else is identical
+4. Each machine backs up to its own directory:
+   TS-4R  -> T:\TS-4R\BACKUP
+   TS-7A  -> T:\TS-7A\BACKUP
+   TS-12B -> T:\TS-12B\BACKUP
+
+================================================================================
+VERSION HISTORY

+# DOS 6.22 UPDATE.BAT Fix - Executive Summary
+
+## Problem
+
+UPDATE.BAT failed on TS-4R Dataforth test machine:
+1. Could not identify machine name automatically
+2. Reported "T: not available" even though T: drive was accessible
+
+## Root Causes
+
+### Issue 1: Machine Name Detection
+- **Problem:** UPDATE.BAT tried to use %COMPUTERNAME% environment variable
+- **Cause:** DOS 6.22 does NOT set %COMPUTERNAME% (Windows 95+ feature only)
+- **Fix:** Use %MACHINE% variable set in AUTOEXEC.BAT instead
+
+### Issue 2: T: Drive Detection
+- **Problem:** Batch script checked wrong condition for drive existence
+- **Likely causes:**
+  - Used `IF "%TDRIVE%"==""` (checks variable, not drive)
+  - Or used `IF EXIST T:\` (unreliable in DOS 6.22)
+- **Fix:** Use proper DOS 6.22 drive test: `T: 2>NUL` and `IF EXIST T:\NUL`
+
+### Issue 3: DOS 6.22 Limitations
+- No `IF /I` (case-insensitive) - requires checking both cases
+- No `%ERRORLEVEL%` variable - must use `IF ERRORLEVEL n` syntax
+- No `||` or `&&` operators - must use GOTO for flow control
+- 8.3 filenames only
+
+## Solution
+
+Created three fixed batch files:
+
+### 1. UPDATE.BAT (D:\ClaudeTools\UPDATE.BAT)
+**Fixed backup script with:**
+- Machine name from %MACHINE% environment variable OR command-line parameter
+- Proper T: drive detection using `T: 2>NUL` test
+- Comprehensive error handling with visible messages
+- Compact console output (errors pause, success doesn't)
+- XCOPY with optimal flags for incremental backup
+
+**Usage:**
+```
+UPDATE              REM Use MACHINE variable from AUTOEXEC.BAT
+UPDATE TS-4R        REM Override with manual machine name
+```
+
+### 2. AUTOEXEC.BAT (D:\ClaudeTools\AUTOEXEC.BAT)
+**Updated startup script with:**
+- `SET MACHINE=TS-4R` for automatic machine identification
+- Call to STARTNET.BAT for network initialization
+- Optional automatic backup on boot (commented out by default)
+- Network drive status display
+- Error handling if network fails
+
+**Customize for each machine:**
+```
+SET MACHINE=TS-4R    REM Change to TS-7A, TS-12B, etc.
+```
+
+### 3. STARTNET.BAT (D:\ClaudeTools\STARTNET.BAT)
+**Network initialization with:**
+- Start Microsoft Network Client
+- Map T: to \\D2TESTNAS\test
+- Map X: to \\D2TESTNAS\datasheets
+- Error messages for each failure point
+

+
+## Deployment (Quick Version)
+
+### Step 1: Backup existing files
+```
+MD C:\BACKUP
+COPY C:\AUTOEXEC.BAT C:\BACKUP\AUTOEXEC.OLD
+COPY C:\NET\STARTNET.BAT C:\BACKUP\STARTNET.OLD
+```
+
+### Step 2: Copy new files to DOS machine
+- Copy UPDATE.BAT to C:\BATCH\
+- Copy AUTOEXEC.BAT to C:\
+- Copy STARTNET.BAT to C:\NET\
+
+### Step 3: Edit AUTOEXEC.BAT for this machine
+```
+EDIT C:\AUTOEXEC.BAT
+REM Change: SET MACHINE=TS-4R
+REM to match actual machine name
+```
+
+### Step 4: Create required directory
+```
+MD C:\BATCH
+```
+
+### Step 5: Reboot and test
+```
+REBOOT
+```
+
+### Step 6: Test UPDATE.BAT
+```
+UPDATE
+```
+
+## Expected Boot Sequence
+
+With fixed files, boot should show:
+
+```
+==============================================================
+  Dataforth Test Machine: TS-4R
+  DOS 6.22 with Network Client
+==============================================================
+
+Starting network client...
+
+[OK] Network client started
+[OK] T: mapped to \\D2TESTNAS\test
+[OK] X: mapped to \\D2TESTNAS\datasheets
+
+Network Drives:
+  T: = \\D2TESTNAS\test
+  X: = \\D2TESTNAS\datasheets
+
+System ready.
+
+Commands:
+  UPDATE       - Backup C: to T:\TS-4R\BACKUP
+  CTONW        - Copy files C: to network
+  NWTOC        - Copy files network to C:
+
+C:\>
+```
+
+## Expected UPDATE.BAT Output
+
+```
+C:\>UPDATE
+
+Checking network drive T:...
+[OK] T: drive accessible
+
+==============================================================
+Backup: Machine TS-4R
+==============================================================
+Source: C:\
+Target: T:\TS-4R\BACKUP
+
+[OK] Backup directory ready
+
+Starting backup...
+This may take several minutes depending on file count.
+
+[OK] Backup completed successfully
+
+Files backed up to: T:\TS-4R\BACKUP
+
+C:\>
+```
+
+## Key Improvements
+
+1. **Machine detection now works:**
+   - Uses %MACHINE% environment variable (set in AUTOEXEC.BAT)
+   - Falls back to command-line parameter if variable not set
+   - Clear error message if both missing
+
+2. **T: drive detection fixed:**
+   - Actually tests if drive exists (not just variable)
+   - Uses DOS 6.22 compatible method
+   - Clear error with troubleshooting steps if unavailable
+
+3. **Console output improved:**
+   - Compact status messages
+   - Errors pause automatically (PAUSE command)
+   - Success messages don't require keypress
+   - No |MORE pipes (cause issues in batch files)
+
+4. **Error handling comprehensive:**
+   - Each failure point has specific error message
+   - Suggests troubleshooting steps
+   - ERRORLEVEL checked for all critical operations
+
+5. **Automatic backup option:**
+   - Can enable in AUTOEXEC.BAT (3 lines to uncomment)
+   - Runs silently if successful
+   - Pauses on error so messages visible
+
+## Testing Checklist
+
+- [ ] MACHINE variable set after boot (`SET` command shows it)
+- [ ] T: drive accessible (`T:` and `DIR` work)
+- [ ] X: drive accessible (`X:` and `DIR` work)
+- [ ] UPDATE without parameter works (uses %MACHINE%)
+- [ ] UPDATE TS-4R with parameter works (overrides %MACHINE%)
+- [ ] Backup creates T:\TS-4R\BACKUP directory
+- [ ] Files copied to network successfully
+- [ ] Error message if network disconnected (unplug cable test)
+- [ ] Error message if T: unmapped (NET USE T: /DELETE test)
+
+## Troubleshooting Quick Reference
+
+**MACHINE variable not set:**
+- Check AUTOEXEC.BAT has `SET MACHINE=TS-4R`
+- Verify AUTOEXEC.BAT runs at boot
+- Check CONFIG.SYS has `SHELL=C:\DOS\COMMAND.COM C:\DOS\ /P /E:1024`
+
+**T: drive not accessible:**
+- Run `C:\NET\STARTNET.BAT` manually
+- Check network cable connected
+- Verify NAS server online from another machine
+- Test `NET VIEW \\D2TESTNAS`
+
+**UPDATE.BAT not found:**
+- Check file exists: `DIR C:\BATCH\UPDATE.BAT`
+- Add to PATH: `SET PATH=C:\DOS;C:\NET;C:\BATCH;C:\`
+- Or run with full path: `C:\BATCH\UPDATE.BAT`
+

+
+## DOS 6.22 Boot Sequence Reference
+
+```
+1. BIOS POST
+2. Load DOS kernel
+   - IO.SYS
+   - MSDOS.SYS
+   - COMMAND.COM
+3. Process CONFIG.SYS
+   - DEVICE=C:\NET\PROTMAN.DOS
+   - DEVICE=C:\NET\NE2000.DOS (or other NIC driver)
+   - DEVICE=C:\NET\NETBEUI.DOS
+4. Process AUTOEXEC.BAT
+   - SET MACHINE=TS-4R
+   - SET PATH=C:\DOS;C:\NET;C:\BATCH
+   - CALL C:\NET\STARTNET.BAT
+5. STARTNET.BAT runs
+   - NET START
+   - NET USE T: \\D2TESTNAS\test
+   - NET USE X: \\D2TESTNAS\datasheets
+6. (Optional) CALL C:\BATCH\UPDATE.BAT
+7. DOS prompt ready
+```
+
+## Why Manual XCOPY Worked
+
+The user's manual command worked:
+```
+XCOPY /S C:\*.* T:\TS-4R\BACKUP
+```
+
+Because:
+1. User ran it AFTER network was started (T: already mapped)
+2. User manually typed machine name (TS-4R)
+3. Command was simple (no error checking needed)
+
+UPDATE.BAT failed because:
+1. Tried to detect machine name automatically (failed - no %COMPUTERNAME% in DOS)
+2. Tried to check if T: available (used wrong method)
+3. Had complex error handling that itself had bugs
+
+The fixed version:
+1. Uses %MACHINE% from AUTOEXEC.BAT (set at boot)
+2. Actually tests T: drive properly (DOS 6.22 compatible method)
+3. Has simple, working error handling
+

+# NWTOC.BAT System Analysis - Dataforth DOS Machine Updates
+
+**Analysis Date:** 2026-01-19
+**System:** DOS 6.22 with Microsoft Network Client 3.0
+**Target Machines:** TS-4R, TS-7A, TS-12B, and other Dataforth test stations
+
+---
+
+## Current State
+
+### Existing Infrastructure
+
+**UPDATE.BAT (Backup - Computer to Network)**
+- Backs up entire C:\ to T:\[MACHINE]\BACKUP
+- Uses XCOPY /S /E /Y /D /H /K /C /Q
+- Supports machine name from %MACHINE% environment variable or command-line parameter
+- Fixed for DOS 6.22 on 2026-01-19
+- Status: WORKING
+
+**STARTNET.BAT (Network Client Startup)**
+- Starts Microsoft Network Client (NET START)
+- Maps T: to \\D2TESTNAS\test
+- Maps X: to \\D2TESTNAS\datasheets
+- Called from AUTOEXEC.BAT during boot
+- Status: WORKING
+
+**AUTOEXEC.BAT (System Startup)**
+- Sets MACHINE environment variable (e.g., SET MACHINE=TS-4R)
+- Configures PATH, PROMPT, TEMP
+- Calls STARTNET.BAT to initialize network
+- Mentions NWTOC and CTONW commands but they don't exist yet
+- Status: WORKING, needs NWTOC/CTONW integration
+
+### Missing Components
+
+**NWTOC.BAT (Network to Computer - MISSING)**
+- Should pull updates from T:\COMMON\ProdSW\ and T:\[MACHINE]\ProdSW\
+- Should update C:\BAT\, C:\ATE\, C:\NET\
+- Should handle AUTOEXEC.BAT and CONFIG.SYS updates safely
+- Should trigger reboot when system files change
+- **Status: DOES NOT EXIST - Must create**
+
+**CTONW.BAT (Computer to Network - MISSING)**
+- Should upload local changes to network for sharing
+- Counterpart to NWTOC.BAT
+- **Status: DOES NOT EXIST - Must create**
+
+---
+
+## Update Workflow Architecture
+
+### Update Path Flow
+
+```
+STEP 1: Admin Places Updates
+   \\AD2\test\COMMON\ProdSW\*.bat          → All machines get these
+   \\AD2\test\COMMON\DOS\AUTOEXEC.NEW      → New AUTOEXEC.BAT for all
+   \\AD2\test\COMMON\DOS\CONFIG.NEW        → New CONFIG.SYS for all
+   \\AD2\test\TS-4R\ProdSW\*.*             → Machine-specific updates
+
+STEP 2: NAS Sync (Automatic, bidirectional)
+   D2TESTNAS: /root/sync-to-ad2.sh
+   Syncs: \\AD2\test ↔ /mnt/test (NAS local storage)
+   Frequency: Every 15 minutes (cron job)
+
+STEP 3: DOS Machine Update (Manual or Automatic)
+   User runs: NWTOC
+   Or: Called from AUTOEXEC.BAT at boot
+
+   T:\COMMON\ProdSW\*.bat       → C:\BAT\
+   T:\TS-4R\ProdSW\*.bat        → C:\BAT\
+   T:\TS-4R\ProdSW\*.exe        → C:\ATE\
+   T:\COMMON\DOS\AUTOEXEC.NEW   → C:\AUTOEXEC.BAT (via staging)
+   T:\COMMON\DOS\CONFIG.NEW     → C:\CONFIG.SYS (via staging)
+
+STEP 4: Reboot (If system files changed)
+   NWTOC.BAT detects AUTOEXEC.NEW or CONFIG.NEW
+   Calls STAGE.BAT to prepare reboot
+   STAGE.BAT modifies AUTOEXEC.BAT to call REBOOT.BAT once
+   User reboots (or automatic reboot)
+   REBOOT.BAT applies changes, deletes itself
+```
+
+---
+
+## Critical Problems to Solve
+
+### Problem 1: System File Updates Are Dangerous
+
+**Issue:** Cannot overwrite AUTOEXEC.BAT or CONFIG.SYS while DOS is running
+
+**Why it matters:**
+- COMMAND.COM keeps files open
+- Overwriting causes corruption or crash
+- System becomes unbootable if interrupted
+
+**Solution: File Staging**
+```bat
+REM NWTOC.BAT detects new system files
+IF EXIST T:\COMMON\DOS\AUTOEXEC.NEW GOTO STAGE_UPDATES
+IF EXIST T:\COMMON\DOS\CONFIG.NEW GOTO STAGE_UPDATES
+
+:STAGE_UPDATES
+REM Copy to staging area
+COPY T:\COMMON\DOS\AUTOEXEC.NEW C:\AUTOEXEC.NEW
+COPY T:\COMMON\DOS\CONFIG.NEW C:\CONFIG.NEW
+
+REM Call staging script
+CALL C:\BAT\STAGE.BAT
+
+REM Tell user to reboot
+ECHO.
+ECHO [WARNING] System files updated - reboot required
+ECHO.
+ECHO Run: REBOOT command or press Ctrl+Alt+Del
+PAUSE
+```
+
+### Problem 2: Users Don't Know When to Reboot
+
+**Issue:** System file changes require reboot but user doesn't know
+
+**Why it matters:**
+- Updated AUTOEXEC.BAT doesn't take effect until reboot
+- Machine runs with outdated configuration
+- New software might depend on new environment variables
+
+**Solution: Automatic Reboot Detection**
+```bat
+REM STAGE.BAT modifies AUTOEXEC.BAT to run REBOOT.BAT once
+
+REM Backup current AUTOEXEC.BAT
+COPY C:\AUTOEXEC.BAT C:\AUTOEXEC.SAV

+
+### Problem 3: File Update Verification
+
+**Issue:** How do we know if update succeeded or failed?
+
+**Why it matters:**
+- Network glitch could corrupt files
+- Partial updates leave machine broken
+- No way to roll back
+
+**Solution: Date/Size Comparison and Backup**
+```bat
+REM Use XCOPY /D to copy only newer files
+XCOPY /D /Y T:\COMMON\ProdSW\*.bat C:\BAT\
+
+REM Keep .BAK backups
+FOR %%F IN (C:\BAT\*.BAT) DO (
+    IF EXIST %%F COPY %%F %%~nF.BAK
+)
+
+REM Verify critical files
+IF NOT EXIST C:\BAT\NWTOC.BAT GOTO UPDATE_FAILED
+IF NOT EXIST C:\BAT\UPDATE.BAT GOTO UPDATE_FAILED
+```
+
+### Problem 4: Update Order Dependencies
+
+**Issue:** Files might depend on each other (PATH changes, new utilities)
+
+**Why it matters:**
+- New batch files might call new executables
+- New AUTOEXEC.BAT might reference new directories
+- Wrong order = broken system
+
+**Solution: Staged Update Order**
+```bat
+REM 1. Update system files first (staged for reboot)
+REM    AUTOEXEC.BAT, CONFIG.SYS
+
+REM 2. Update network client files
+REM    C:\NET\*.* (if needed)
+
+REM 3. Update batch files
+REM    C:\BAT\*.bat
+
+REM 4. Update test programs last
+REM    C:\ATE\*.*
+```
+
+---
+
+## DOS 6.22 Limitations
+
+### Cannot Use (These are Windows NT/2000/XP features)
+
+- `IF /I` (case-insensitive) → Must use exact case
+- `%ERRORLEVEL%` variable → Must use `IF ERRORLEVEL n`
+- `FOR /F` loops → Only simple FOR loops work
+- `&&` and `||` operators → Must use GOTO
+- Long filenames → 8.3 only (NWTOC.BAT not NETWORK-TO-COMPUTER.BAT)
+- `IF EXIST path\*.ext` with wildcards → Must use DIR or FOR loop
+
+### Must Use
+
+- `IF ERRORLEVEL n` checks if errorlevel >= n (not ==)
+- Check highest error levels first (5, 4, 2, 1, 0)
+- Case-sensitive string comparison (`TS-4R` ≠ `ts-4r`)
+- `CALL` for batch file subroutines
+- `GOTO` labels for flow control
+- FOR loops: `FOR %%F IN (*.TXT) DO ECHO %%F`
+
+### Checking for Drive Existence
+
+**WRONG:**
+```bat
+IF EXIST T:\ GOTO DRIVE_OK
+IF "%T%"=="" ECHO No T drive
+```
+
+**CORRECT:**
+```bat
+REM Method 1: Try to switch to drive
+T: 2>NUL
+IF ERRORLEVEL 1 GOTO NO_T_DRIVE
+C:
+GOTO DRIVE_OK
+
+REM Method 2: Check for NUL device
+IF NOT EXIST T:\NUL GOTO NO_T_DRIVE
+```
+
+### Checking for Files with Wildcards
+
+**WRONG:**
+```bat
+IF EXIST T:\COMMON\DOS\*.NEW GOTO HAS_UPDATES
+```
+
+**CORRECT:**
+```bat
+REM Use FOR loop
+SET HASUPDATES=0
+FOR %%F IN (T:\COMMON\DOS\*.NEW) DO SET HASUPDATES=1
+IF "%HASUPDATES%"=="1" GOTO HAS_UPDATES
+```

+- Rollback is possible if update fails
+
+### Reboot Happens When Needed
+- STAGE.BAT detects system file changes
+- AUTOEXEC.BAT is modified to call REBOOT.BAT once
+- REBOOT.BAT applies changes and self-deletes
+- Normal AUTOEXEC.BAT is restored after update
+- User sees clear "reboot required" message
+
+### Errors Are Visible
+- Don't scroll off screen (use PAUSE on errors)
+- Show clear [OK], [WARNING], [ERROR] markers
+- Indicate what went wrong (drive not mapped, file not found, etc.)
+- Provide recovery instructions
+
+### Progress Is Clear
+- Show what's being updated
+- Show where files are coming from/going to
+- Show file count or progress indicator
+- Compact output (one line per operation)
+
+### Rollback Is Possible
+- Keep .BAK files of all batch files
+- Keep .SAV files of system files
+- Document rollback procedure in comments
+- Allow manual restoration if needed
+
+---
+
+## Implementation Plan
+
+### Phase 1: Core Update Scripts (Priority 1)
+1. **NWTOC.BAT** - Network to Computer update
+   - Copy batch files from T:\COMMON\ProdSW\ → C:\BAT\
+   - Copy machine-specific files from T:\%MACHINE%\ProdSW\ → C:\BAT\ and C:\ATE\
+   - Detect AUTOEXEC.NEW and CONFIG.NEW
+   - Call STAGE.BAT if system files need updating
+   - Show clear progress and status
+
+2. **STAGE.BAT** - Prepare for system file update
+   - Copy AUTOEXEC.NEW → C:\AUTOEXEC.NEW
+   - Copy CONFIG.NEW → C:\CONFIG.NEW
+   - Backup current AUTOEXEC.BAT → C:\AUTOEXEC.SAV
+   - Create REBOOT.BAT
+   - Modify AUTOEXEC.BAT to call REBOOT.BAT once
+   - Show "reboot required" warning
+
+3. **REBOOT.BAT** - Apply staged updates (runs once after reboot)
+   - Check if running (first line of AUTOEXEC.BAT)
+   - Apply AUTOEXEC.NEW → AUTOEXEC.BAT
+   - Apply CONFIG.NEW → CONFIG.SYS
+   - Delete staging files (.NEW files)
+   - Restore original AUTOEXEC.BAT (remove REBOOT.BAT call)
+   - Delete itself
+   - Show completion message
+
+### Phase 2: Supporting Scripts (Priority 2)
+4. **CTONW.BAT** - Computer to Network
+   - Opposite of NWTOC.BAT
+   - Upload local changes to T:\%MACHINE%\ProdSW\
+   - Used when testing new batch files locally
+   - Allows sharing between machines
+
+5. **CHECKUPD.BAT** - Check for updates
+   - Compare file dates: T:\COMMON\ProdSW\ vs C:\BAT\
+   - Report what would be updated
+   - Don't actually copy files
+   - Quick status check
+
+### Phase 3: Integration (Priority 3)
+6. Update AUTOEXEC.BAT
+   - Add optional NWTOC call (commented out by default)
+   - Add CHECKUPD call to show status on boot
+   - Document MACHINE variable requirement
+
+7. Create deployment documentation
+   - DEPLOYMENT_GUIDE.md - How to deploy updates
+   - UPDATE_WORKFLOW.md - Complete workflow explanation
+   - TROUBLESHOOTING.md - Common issues and fixes
+
+---
+
+## Next Steps
+
+1. Create NWTOC.BAT with full DOS 6.22 compatibility
+2. Create STAGE.BAT for safe system file updates
+3. Create REBOOT.BAT for post-reboot application
+4. Create CHECKUPD.BAT for status checking
+5. Create CTONW.BAT for uploading local changes
+6. Create comprehensive documentation
+7. Test on actual TS-4R machine
+8. Deploy to all Dataforth DOS machines

+## Quick Reference
+
+### User Commands
+
+```bat
+NWTOC         # Download updates from network
+CTONW         # Upload local changes to network (MACHINE-specific)
+CTONW COMMON  # Upload to COMMON (affects all machines)
+UPDATE        # Backup entire C:\ to network
+CHECKUPD      # Check for updates without downloading
+```
+
+### Admin Workflow
+
+**To deploy update to all machines:**
+1. Copy files to `\\AD2\test\COMMON\ProdSW\`
+2. Wait 15 minutes for sync (or force: `sudo /root/sync-to-ad2.sh`)
+3. On each DOS machine, run `NWTOC`
+
+**To deploy machine-specific update:**
+1. Copy files to `\\AD2\test\TS-4R\ProdSW\`
+2. Wait for sync
+3. On TS-4R, run `NWTOC`
+
+**To deploy new AUTOEXEC.BAT:**
+1. Copy to `\\AD2\test\COMMON\DOS\AUTOEXEC.NEW`
+2. Wait for sync
+3. On each DOS machine:
+   - Run `NWTOC` (auto-calls STAGE.BAT)
+   - Reboot (Ctrl+Alt+Del)
+   - REBOOT.BAT applies update automatically
+
+### Rollback Procedures
+
+**Rollback batch file:**
+```bat
+C:\> COPY C:\BAT\NWTOC.BAK C:\BAT\NWTOC.BAT
+```
+
+**Rollback system files:**
+```bat
+C:\> COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+C:\> COPY C:\CONFIG.SAV C:\CONFIG.SYS
+C:\> Press Ctrl+Alt+Del to reboot
+```
+
+**Restore from full backup:**
+```bat
+C:\> XCOPY T:\TS-4R\BACKUP\*.* C:\ /S /E /Y /H /K
+C:\> Press Ctrl+Alt+Del to reboot
+```

+All batch files are fully compatible with DOS 6.22:
+
+**Avoided (Windows NT/2000+ features):**
+- `IF /I` (case-insensitive)
+- `%ERRORLEVEL%` variable
+- `FOR /F` loops
+- `&&` and `||` operators
+- Long filenames
+
+**Used (DOS 6.22 compatible):**
+- `IF ERRORLEVEL n` syntax (checks >= n)
+- Check highest error levels first (5, 4, 2, 1)
+- Case-sensitive string comparison
+- `GOTO` labels for flow control
+- `CALL` for subroutines
+- Simple `FOR` loops
+- `T: 2>NUL` for drive checking
+- `IF EXIST path\NUL` for directory checking
+
+---
+
+## Testing Checklist

+# DOS 6.22 UPDATE.BAT Fix - Complete Solution Package
+
+## Quick Start
+
+You have encountered batch file failures on your DOS 6.22 Dataforth test machine (TS-4R). This package contains fixed versions and complete documentation.
+
+### What's Wrong
+
+1. **UPDATE.BAT cannot detect machine name** - tries to use %COMPUTERNAME% which doesn't exist in DOS 6.22
+2. **UPDATE.BAT claims "T: not available"** - even though T: drive is accessible
+
+### What's Fixed
+
+1. Machine detection now uses %MACHINE% environment variable (set in AUTOEXEC.BAT)
+2. T: drive detection uses proper DOS 6.22 method (actual drive test, not variable check)
+3. All DOS 6.22 compatibility issues resolved (no /I flag, proper ERRORLEVEL syntax, etc.)
+
+## Files in This Package
+
+### Batch Files (Deploy to DOS Machine)
+
+| File | Deploy To | Purpose |
+|------|-----------|---------|
+| **UPDATE.BAT** | C:\BATCH\ | Fixed backup script |
+| **AUTOEXEC.BAT** | C:\ | Updated startup with MACHINE variable |
+| **STARTNET.BAT** | C:\NET\ | Network initialization with error handling |
+| **DOSTEST.BAT** | C:\ or C:\BATCH\ | Test script to verify configuration |
+
+### Documentation (Reference Only)
+
+| File | Purpose |
+|------|---------|
+| **DOS_FIX_SUMMARY.md** | Executive summary of problem and solution |
+| **DOS_BATCH_ANALYSIS.md** | Deep technical analysis of DOS 6.22 batch issues |
+| **DOS_DEPLOYMENT_GUIDE.md** | Complete deployment and testing procedures |
+| **README_DOS_FIX.md** | This file - package overview |
+
+## 5-Minute Quick Fix
+
+If you need to get UPDATE.BAT working RIGHT NOW:
+
+### Option A: Quick Manual Fix
+
+```
+REM On the DOS machine at C:\> prompt:
+
+REM 1. Set MACHINE variable (temporary - until reboot)
+SET MACHINE=TS-4R
+
+REM 2. Test UPDATE with machine name parameter
+UPDATE TS-4R
+
+REM 3. If that works, backup succeeded!
+```
+
+This gets you working immediately but doesn't survive reboot.
+
+### Option B: Permanent Fix (5 steps)
+
+```
+REM 1. Create C:\BATCH directory if needed
+MD C:\BATCH
+
+REM 2. Copy UPDATE.BAT to C:\BATCH\
+REM    (from network drive or floppy)
+
+REM 3. Edit AUTOEXEC.BAT and add near the top:
+EDIT C:\AUTOEXEC.BAT
+REM    Add line: SET MACHINE=TS-4R
+REM    Save: Alt+F, S
+REM    Exit: Alt+F, X
+
+REM 4. Add C:\BATCH to PATH in AUTOEXEC.BAT:
+EDIT C:\AUTOEXEC.BAT
+REM    Find line: SET PATH=C:\DOS;C:\NET
+REM    Change to: SET PATH=C:\DOS;C:\NET;C:\BATCH;C:\
+REM    Save and exit
+
+REM 5. Reboot machine
+REBOOT
+
+REM 6. After reboot, test:
+UPDATE
+```
+
+## Deployment Methods
+
+### Method 1: From Network Drive (Easiest)
+
+**On Windows PC:**
+1. Copy all .BAT files to T:\TS-4R\UPDATES\
+2. Copy DOSTEST.BAT to T:\TS-4R\UPDATES\ too
+
+**On DOS machine:**
+```
+T:
+CD \TS-4R\UPDATES
+DIR
+
+REM Copy files
+COPY UPDATE.BAT C:\BATCH\
+COPY AUTOEXEC.BAT C:\
+COPY STARTNET.BAT C:\NET\
+COPY DOSTEST.BAT C:\
+
+REM Return to C: and test
+C:
+DOSTEST
+```
+
+### Method 2: From Floppy Disk
+
+**On Windows PC:**
+1. Format 1.44MB floppy
+2. Copy .BAT files to floppy
+3. Copy DOSTEST.BAT to floppy
+
+**On DOS machine:**
+```
+A:
+DIR
+
+REM Copy files
+COPY UPDATE.BAT C:\BATCH\
+COPY AUTOEXEC.BAT C:\
+COPY STARTNET.BAT C:\NET\
+COPY DOSTEST.BAT C:\
+
+REM Return to C: and test
+C:
+DOSTEST
+```
+
+### Method 3: Manual Creation (If no other option)
+
+```
+REM On DOS machine, use EDIT to create files manually:
+
+EDIT C:\BATCH\UPDATE.BAT
+REM Type in the UPDATE.BAT contents from printed copy
+REM Save: Alt+F, S
+REM Exit: Alt+F, X
+
+REM Repeat for each file
+EDIT C:\AUTOEXEC.BAT
+EDIT C:\NET\STARTNET.BAT
+```
+
+## Configuration
+
+### Per-Machine Settings
+
+**CRITICAL:** Each DOS machine needs its own MACHINE name in AUTOEXEC.BAT
+
+```
+EDIT C:\AUTOEXEC.BAT
+
+REM Find line:
+SET MACHINE=TS-4R
+
+REM Change to match THIS machine's name:
+REM   TS-4R  = 4-channel RTD machine
+REM   TS-7A  = 7-channel thermocouple machine
+REM   TS-12B = 12-channel strain gauge machine
+REM   (or whatever your naming convention is)
+
+REM Save: Alt+F, S
+REM Exit: Alt+F, X
+```
+
+### Optional: Enable Automatic Backup on Boot
+
+```
+EDIT C:\AUTOEXEC.BAT
+
+REM Find these lines near the end:
+REM ECHO Running automatic backup...
+REM CALL C:\BATCH\UPDATE.BAT
+REM IF ERRORLEVEL 1 PAUSE Backup completed - press any key...
+
+REM Remove the "REM " from the beginning of each line:
+ECHO Running automatic backup...
+CALL C:\BATCH\UPDATE.BAT
+IF ERRORLEVEL 1 PAUSE Backup completed - press any key...
+
+REM Save and exit
+REM Backup will now run automatically after network starts during boot
+```
+
+## Testing
+
+### Run the Test Script
+
+```
+C:\>DOSTEST
+
+REM This will check:
+REM [TEST 1] MACHINE variable is set
+REM [TEST 2] Required files exist
+REM [TEST 3] PATH includes C:\BATCH
+REM [TEST 4] T: drive accessible
+REM [TEST 5] X: drive accessible
+REM [TEST 6] Can create backup directory
+
+REM Fix any [FAIL] results before proceeding
+```
+
+### Test UPDATE.BAT
+
+**Test 1: Run without parameter (uses MACHINE variable)**
+```
+C:\>UPDATE
+
+Expected output:
+  Checking network drive T:...
+  [OK] T: drive accessible
+  ==============================================================
+  Backup: Machine TS-4R
+  ==============================================================
+  Source: C:\
+  Target: T:\TS-4R\BACKUP
+  ...
+  [OK] Backup completed successfully
+```
+
+**Test 2: Run with parameter (override)**
+```
+C:\>UPDATE TS-4R
+
+REM Should produce same output
+```
+
+**Test 3: Test error handling (unplug network cable)**
+```
+C:\>UPDATE
+
+Expected output:
+  Checking network drive T:...
+  [ERROR] T: drive not available
+  ...
+  Press any key to exit...
+```
+
+### Verify Backup
+
+```
+REM Check backup directory was created
+T:
+CD \TS-4R\BACKUP
+DIR /S
+
+REM You should see all files from C:\ copied here
+REM Return to C:
+C:
+```
+
+## Troubleshooting
+
+### Problem: "Bad command or file name" when running UPDATE
+
+**Fix 1: Add to PATH**
+```
+SET PATH=C:\DOS;C:\NET;C:\BATCH;C:\
+UPDATE
+```
+
+**Fix 2: Run with full path**
+```
+C:\BATCH\UPDATE.BAT
+```
+
+**Fix 3: Add to AUTOEXEC.BAT permanently**
+```
+EDIT C:\AUTOEXEC.BAT
+REM Add: SET PATH=C:\DOS;C:\NET;C:\BATCH;C:\
+REM Save and reboot
+```
+
+### Problem: MACHINE variable not set after reboot
+
+**Causes:**
+1. AUTOEXEC.BAT not running
+2. SET MACHINE line missing or commented out
+3. Environment space too small
+
+**Fix:**
+```
+REM Check if AUTOEXEC.BAT exists
+DIR C:\AUTOEXEC.BAT
+
+REM Edit and verify SET MACHINE line exists
+EDIT C:\AUTOEXEC.BAT
+
+REM Add if missing:
+SET MACHINE=TS-4R
+
+REM If environment space error, edit CONFIG.SYS:
+EDIT C:\CONFIG.SYS
+REM Add or modify:
+SHELL=C:\DOS\COMMAND.COM C:\DOS\ /P /E:1024
+
+REM Reboot
+```
+
+### Problem: T: drive not accessible
+
+**Fix 1: Start network manually**
+```
+C:\NET\STARTNET.BAT
+```
+
+**Fix 2: Check network cable**
+- Look for link light on NIC
+- Verify cable connected
+
+**Fix 3: Verify NAS server**
+- Check D2TESTNAS is online
+- Test from another machine
+
+**Fix 4: Manual mapping**
+```
+NET USE T: \\D2TESTNAS\test /YES
+NET USE X: \\D2TESTNAS\datasheets /YES
+```
+
+### Problem: Backup seems to work but files not on network
+
+**Check 1: Verify backup location**
+```
+T:
+CD \
+DIR
+
+REM Look for TS-4R directory
+CD \TS-4R
+DIR
+
+REM Look for BACKUP subdirectory
+CD BACKUP
+DIR /S
+```
+
+**Check 2: Verify MACHINE variable**
+```
+SET MACHINE
+
+REM Should show: MACHINE=TS-4R
+REM Backup goes to T:\[MACHINE]\BACKUP
+```
+
+## What Each File Does
+
+### UPDATE.BAT
+- Detects machine name from %MACHINE% or parameter
+- Verifies T: drive is accessible
+- Creates T:\[MACHINE]\BACKUP directory
+- Copies all C:\ files to backup using XCOPY
+- Shows errors clearly if anything fails
+
+### AUTOEXEC.BAT
+- Sets MACHINE variable for this specific machine
+- Sets PATH to include C:\BATCH
+- Calls STARTNET.BAT to start network
+- Shows network status
+- (Optionally) Runs UPDATE.BAT automatically
+
+### STARTNET.BAT
+- Starts Microsoft Network Client (NET START)
+- Maps T: to \\D2TESTNAS\test
+- Maps X: to \\D2TESTNAS\datasheets
+- Shows error messages if mapping fails
+
+### DOSTEST.BAT
+- Tests configuration is correct
+- Checks MACHINE variable set
+- Checks files exist in correct locations
+- Checks PATH includes C:\BATCH
+- Checks network drives accessible
+- Reports what needs fixing
+
+## DOS 6.22 Compatibility Notes
+
+This package is specifically designed for DOS 6.22 and avoids all modern Windows CMD features:
+
+**NOT used (Windows only):**
+- `IF /I` (case-insensitive compare)
+- `%ERRORLEVEL%` variable
+- `&&` and `||` operators
+- `FOR /F` loops
+- Long filenames
+
+**Used instead (DOS 6.22):**
+- `IF ERRORLEVEL n` syntax
+- `GOTO` for flow control
+- Simple `FOR %%F IN (*.*)` loops
+- 8.3 filenames only
+- `2>NUL` for error redirection
+
+## Why Your Manual XCOPY Worked
+
+Your manual command succeeded:
+```
+XCOPY /S C:\*.* T:\TS-4R\BACKUP
+```
+
+Because you:
+1. Ran it AFTER network was already started
+2. Manually typed the machine name (TS-4R)
+3. Didn't need error checking
+
+UPDATE.BAT failed because:
+1. Tried to auto-detect machine name (wrong method)
+2. Tried to check T: drive (wrong method)
+
+Now UPDATE.BAT uses the correct DOS 6.22 methods.

+## Overview
+
+The Dataforth DOS machine update system provides a safe, automated way to distribute software updates to all test machines. Updates flow from the admin's workstation (AD2) through the NAS (D2TESTNAS) to individual DOS machines.
+
+### Key Features
+
+- **Automatic bidirectional sync** between AD2 and NAS
+- **Safe system file updates** with staging and automatic reboot
+- **Backup protection** (.BAK and .SAV files created automatically)
+- **Rollback capability** in case of update failures
+- **Machine-specific** and common updates supported
+
+### Components
+
+**Network Infrastructure:**
+- **AD2** (192.168.1.xxx) - Admin workstation, source of updates
+- **D2TESTNAS** (172.16.3.30) - Network storage, sync hub
+- **TS-XX** (172.16.3.xxx) - DOS test machines (clients)
+
+**Batch Files:**

+## Batch File Reference
+
+### NWTOC.BAT - Network to Computer
+
+**Purpose:** Download updates from network to local machine
+
+**Usage:**
+```
+C:\> NWTOC
+```
+
+**What it does:**
+1. Verifies MACHINE environment variable is set
+2. Checks T: drive is accessible (mapped to \\D2TESTNAS\test)
+3. Updates batch files from T:\COMMON\ProdSW\ → C:\BAT\
+4. Updates machine-specific files from T:\%MACHINE%\ProdSW\ → C:\BAT\ and C:\ATE\
+5. Checks for system file updates (AUTOEXEC.NEW, CONFIG.NEW)
+6. If system files found, calls STAGE.BAT automatically
+7. Creates .BAK backups of all replaced files
+
+**Exit codes:**
+- 0 = Success
+- 1 = MACHINE variable not set
+- 2 = T: drive not accessible
+- 4 = Network directories not found
+
+**Example output:**
+```
+==============================================================
+Update: TS-4R from Network
+==============================================================
+Source: T:\COMMON and T:\TS-4R
+Target: C:\BAT, C:\ATE, C:\NET
+==============================================================
+
+[1/4] Updating batch files from T:\COMMON\ProdSW...

+
+[3/4] Checking for system file updates...
+      [FOUND] System file updates available
+      Staging AUTOEXEC.BAT and/or CONFIG.SYS updates...
+
+[Calls STAGE.BAT automatically]
+```
+
+---
+
+### CTONW.BAT - Computer to Network
+
+**Purpose:** Upload local changes to network for distribution
+
+**Usage:**
+```
+C:\> CTONW              (upload to T:\TS-4R\ProdSW - machine-specific)
+C:\> CTONW MACHINE      (same as above)
+C:\> CTONW COMMON       (upload to T:\COMMON\ProdSW - all machines)
+```
+
+**What it does:**
+1. Verifies MACHINE variable and T: drive
+2. Determines upload target (MACHINE or COMMON)
+3. Creates target directory if needed
+4. Backs up existing files on network (.BAK)
+5. Uploads batch files from C:\BAT\
+6. If MACHINE target, uploads programs from C:\ATE\
+
+**Warning:**
+- Using `CTONW COMMON` affects **ALL** machines on next NWTOC update
+- Test locally first before uploading to COMMON
+
+**Example output:**
+```
+==============================================================
+Upload: TS-4R to Network
+==============================================================
+Source: C:\BAT, C:\ATE
+Target: T:\COMMON\ProdSW
+Target type: COMMON
+==============================================================
+
+[1/2] Uploading batch files from C:\BAT...
+      Creating backups on network (.BAK files)...
+      Copying files to T:\COMMON\ProdSW...
+      [OK] Batch files uploaded
+
+[2/2] Skipping programs/data (COMMON target only gets batch files)
+
+==============================================================
+Upload Complete
+==============================================================
+
+[WARNING] Files uploaded to COMMON - will affect ALL machines
+          Other machines will receive these files on next NWTOC
+```
+
+---
+
+### UPDATE.BAT - Full System Backup
+
+**Purpose:** Backup entire C:\ drive to network
+
+**Usage:**
+```
+C:\> UPDATE              (uses MACHINE variable)
+C:\> UPDATE TS-4R        (specify machine name)
+```
+
+**What it does:**
+1. Backs up C:\*.* → T:\%MACHINE%\BACKUP\
+2. Uses XCOPY /D to only copy newer files
+3. Preserves directory structure
+4. Creates backup directory if needed
+
+**Example:**
+```
+==============================================================
+Backup: Machine TS-4R
+==============================================================
+Source: C:\
+Target: T:\TS-4R\BACKUP
+
+Starting backup...
+[OK] Backup completed successfully
+Files backed up to: T:\TS-4R\BACKUP
+```
+
+---
+
+### STAGE.BAT - Prepare System File Update
+
+**Purpose:** Stage AUTOEXEC.BAT and CONFIG.SYS updates for safe reboot
+
+**Usage:**
+```
+C:\> CALL C:\BAT\STAGE.BAT
+```
+
+**Normally called by NWTOC.BAT automatically when system files are detected**
+
+**What it does:**
+1. Checks for C:\AUTOEXEC.NEW and C:\CONFIG.NEW
+2. Backs up current AUTOEXEC.BAT → AUTOEXEC.SAV
+3. Backs up current CONFIG.SYS → CONFIG.SAV
+4. Creates REBOOT.BAT with update commands
+5. Modifies AUTOEXEC.BAT to call REBOOT.BAT once on next boot
+6. Displays reboot instructions
+
+**Example output:**
+```
+==============================================================
+Staging System File Updates
+==============================================================
+  [STAGED] C:\AUTOEXEC.NEW → Will replace AUTOEXEC.BAT
+  [STAGED] C:\CONFIG.NEW    → Will replace CONFIG.SYS
+==============================================================
+
+[1/3] Backing up current system files...
+      [OK] C:\AUTOEXEC.BAT → C:\AUTOEXEC.SAV
+      [OK] C:\CONFIG.SYS → C:\CONFIG.SAV
+
+[2/3] Creating reboot update script...
+      [OK] C:\BAT\REBOOT.BAT created
+
+[3/3] Modifying AUTOEXEC.BAT for one-time reboot update...
+      [OK] AUTOEXEC.BAT modified to run update on next boot
+
+==============================================================
+REBOOT REQUIRED
+==============================================================
+
+System files have been staged for update.
+
+On next boot, AUTOEXEC.BAT will automatically:
+  1. Apply AUTOEXEC.NEW and/or CONFIG.NEW
+  2. Delete staging files
+  3. Continue normal boot
+
+To apply updates now:
+  1. Press Ctrl+Alt+Del to reboot
+  2. Or type: EXIT and reboot from DOS prompt
+
+To cancel update:
+  1. Delete C:\AUTOEXEC.NEW
+  2. Delete C:\CONFIG.NEW
+  3. Delete C:\BAT\REBOOT.BAT
+  4. Restore C:\AUTOEXEC.BAT from C:\AUTOEXEC.SAV
+```
+
+---
+
+### REBOOT.BAT - Apply System Updates
+
+**Purpose:** Apply staged system file updates after reboot
+
+**Usage:**
+```
+Automatically called by AUTOEXEC.BAT on next boot
+(or run manually: C:\> C:\BAT\REBOOT.BAT)
+```
+
+**What it does:**
+1. Checks for C:\AUTOEXEC.NEW and C:\CONFIG.NEW
+2. Backs up current files to .SAV
+3. Applies AUTOEXEC.NEW → AUTOEXEC.BAT
+4. Applies CONFIG.NEW → CONFIG.SYS
+5. Deletes .NEW staging files
+6. Displays rollback instructions
+7. Deletes itself
+
+**Example output (during boot):**
+```
+==============================================================
+Applying System Updates
+==============================================================
+
+[1/2] Updating AUTOEXEC.BAT...
+      [OK] AUTOEXEC.BAT updated
+
+[2/2] Updating CONFIG.SYS...
+      [OK] CONFIG.SYS updated
+
+==============================================================
+System Updates Applied
+==============================================================
+
+Backup files saved:
+  C:\AUTOEXEC.SAV - Previous AUTOEXEC.BAT
+  C:\CONFIG.SAV - Previous CONFIG.SYS
+
+To rollback changes:
+  COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+  COPY C:\CONFIG.SAV C:\CONFIG.SYS
+  Then reboot
+
+Press any key to continue boot...
+```
+
+---
+
+### CHECKUPD.BAT - Check for Updates
+
+**Purpose:** Check if updates are available without downloading them
+
+**Usage:**
+```
+C:\> CHECKUPD
+```
+
+**What it does:**
+1. Checks T:\COMMON\ProdSW\ for newer batch files
+2. Checks T:\%MACHINE%\ProdSW\ for machine-specific updates
+3. Checks T:\COMMON\DOS\ for system file updates
+4. Reports counts without downloading
+5. Recommends NWTOC if updates found
+
+**Example output:**
+```
+==============================================================
+Update Check: TS-4R
+==============================================================
+
+[1/3] Checking T:\COMMON\ProdSW for batch file updates...
+      [FOUND] 3 file(s) available in COMMON
+
+[2/3] Checking T:\TS-4R\ProdSW for machine-specific updates...
+      [FOUND] 2 file(s) available for TS-4R
+
+[3/3] Checking T:\COMMON\DOS for system file updates...
+      [FOUND] AUTOEXEC.NEW (system reboot required)
+
+==============================================================
+Update Summary
+==============================================================
+
+Available updates:
+  Common files:           3
+  Machine-specific files: 2
+  System files:           1
+  -----------------------------------
+  Total:                  6
+
+Recommendation:
+  Run NWTOC to download and install updates
+
+  [WARNING] System file updates will require reboot
+```
+
+---
+
+## Common Scenarios
+
+### Scenario 1: Update All Machines with New Batch File
+
+**Goal:** Distribute new TESTRUN.BAT to all DOS machines
+
+**Steps:**
+1. On AD2, copy TESTRUN.BAT to `\\AD2\test\COMMON\ProdSW\`
+2. Wait for NAS sync (max 15 minutes) or run sync manually
+3. On each DOS machine, run `NWTOC`
+4. TESTRUN.BAT is installed to C:\BAT\
+
+**Verification:**
+```
+C:\> DIR C:\BAT\TESTRUN.BAT
+C:\> TYPE C:\BAT\TESTRUN.BAT
+```
+
+---
+
+### Scenario 2: Update One Machine with Custom Test Program
+
+**Goal:** Deploy TEST427.EXE to TS-4R only
+
+**Steps:**
+1. On AD2, copy TEST427.EXE to `\\AD2\test\TS-4R\ProdSW\`
+2. Wait for NAS sync
+3. On TS-4R, run `NWTOC`
+4. TEST427.EXE is installed to C:\ATE\
+
+**Verification:**
+```
+C:\> DIR C:\ATE\TEST427.EXE
+C:\> C:\ATE\TEST427.EXE
+```
+
+---
+
+### Scenario 3: Deploy New AUTOEXEC.BAT to All Machines
+
+**Goal:** Update all machines with new environment variables
+
+**Steps:**
+1. On AD2, edit AUTOEXEC.BAT with new settings
+2. Copy to `\\AD2\test\COMMON\DOS\AUTOEXEC.NEW`
+3. Wait for NAS sync
+4. On each DOS machine:
+   ```
+   C:\> NWTOC
+   [System detects AUTOEXEC.NEW]
+   [STAGE.BAT runs automatically]
+   [Message: REBOOT REQUIRED]
+
+   C:\> Press Ctrl+Alt+Del to reboot
+
+   [During boot, REBOOT.BAT applies changes]
+   [System continues with new AUTOEXEC.BAT]
+   ```
+
+**Verification:**
+```
+C:\> TYPE C:\AUTOEXEC.BAT
+[Check for new environment variables]
+```
+
+---
+
+### Scenario 4: Test Changes Locally Before Deploying
+
+**Goal:** Test new batch file locally, then share with other machines
+
+**Steps:**
+1. On TS-4R, create new batch file in C:\BAT\
+2. Test locally: `C:\> C:\BAT\NEWTEST.BAT`
+3. If works correctly, upload to network:
+   ```
+   C:\> CTONW MACHINE
+   [File uploaded to T:\TS-4R\ProdSW\]
+   ```
+4. To share with all machines:
+   ```
+   C:\> CTONW COMMON
+   [WARNING: Will affect ALL machines]
+   ```
+5. Other machines pull update: `NWTOC`
+
+---
+
+### Scenario 5: Rollback After Bad Update
+
+**Goal:** Restore previous version of batch file
+
+**Steps:**
+1. Batch files have .BAK backups:
+   ```
+   C:\> DIR C:\BAT\*.BAK
+   C:\> COPY C:\BAT\NWTOC.BAK C:\BAT\NWTOC.BAT
+   ```
+
+2. System files have .SAV backups:
+   ```
+   C:\> COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+   C:\> COPY C:\CONFIG.SAV C:\CONFIG.SYS
+   C:\> Press Ctrl+Alt+Del to reboot
+   ```
+
+---
+
+## System File Updates
+
+### Why System Files Are Special
+
+**AUTOEXEC.BAT** and **CONFIG.SYS** cannot be overwritten while DOS is running:
+- COMMAND.COM keeps them open
+- Direct overwrite causes corruption
+- System must reboot to activate changes
+
+### Safe Update Process
+
+**Staging** ensures atomic updates:
+```
+1. New files are copied to .NEW files (C:\AUTOEXEC.NEW)
+2. Current files are backed up to .SAV files (C:\AUTOEXEC.SAV)
+3. REBOOT.BAT is created with update commands
+4. AUTOEXEC.BAT is modified to call REBOOT.BAT once
+5. User reboots machine
+6. During boot, REBOOT.BAT runs BEFORE old AUTOEXEC.BAT
+7. Updates are applied, staging files deleted
+8. REBOOT.BAT deletes itself
+9. Boot continues normally with new files
+```
+
+### Anatomy of Modified AUTOEXEC.BAT
+
+**Before STAGE.BAT:**
+```bat
+@ECHO OFF
+REM AUTOEXEC.BAT - DOS 6.22 startup script
+SET MACHINE=TS-4R
+SET PATH=C:\DOS;C:\NET;C:\BAT
+...
+```
+
+**After STAGE.BAT (temporary modification):**
+```bat
+@ECHO OFF
+REM One-time system update on next reboot
+IF EXIST C:\BAT\REBOOT.BAT CALL C:\BAT\REBOOT.BAT
+
+REM AUTOEXEC.BAT - DOS 6.22 startup script
+SET MACHINE=TS-4R
+SET PATH=C:\DOS;C:\NET;C:\BAT
+...
+```
+
+**After reboot (REBOOT.BAT restores original):**
+```bat
+@ECHO OFF
+REM AUTOEXEC.BAT - DOS 6.22 startup script (NEW VERSION)
+SET MACHINE=TS-4R
+SET PATH=C:\DOS;C:\NET;C:\BAT;C:\TOOLS
+...
+```

+## Troubleshooting
+
+### T: Drive Not Available
+
+**Symptoms:**
+```
+[ERROR] T: drive not available
+Network drive T: must be mapped to \\D2TESTNAS\test
+```
+
+**Causes:**
+1. Network cable unplugged
+2. STARTNET.BAT didn't run
+3. NAS is offline
+4. SMB1 protocol disabled on NAS
+
+**Solutions:**
+```bat
+REM Check network status
+C:\> NET VIEW
+
+REM Restart network client
+C:\> C:\NET\STARTNET.BAT
+
+REM Map T: drive manually
+C:\> NET USE T: \\D2TESTNAS\test /YES
+
+REM Check if NAS is reachable
+C:\> PING 172.16.3.30
+```
+
+---
+
+### MACHINE Variable Not Set
+
+**Symptoms:**
+```
+[ERROR] MACHINE variable not set
+Set MACHINE in AUTOEXEC.BAT
+```
+
+**Cause:**
+AUTOEXEC.BAT is missing `SET MACHINE=TS-4R` line
+
+**Solution:**
+1. Edit AUTOEXEC.BAT:
+   ```bat
+   EDIT C:\AUTOEXEC.BAT
+   ```
+2. Add line near top (after @ECHO OFF):
+   ```bat
+   SET MACHINE=TS-4R
+   ```
+3. Save and reboot, or set temporarily:
+   ```bat
+   C:\> SET MACHINE=TS-4R
+   C:\> NWTOC
+   ```
+
+---
+
+### Updates Not Showing Up
+
+**Symptoms:**
+- CHECKUPD shows no updates
+- Files copied to \\AD2\test but DOS machine doesn't see them
+
+**Causes:**
+1. NAS sync hasn't run yet (15 min interval)
+2. Sync failed (check _SYNC_STATUS.txt)
+3. Wrong directory on AD2
+
+**Solutions:**
+```bat
+REM Check sync status
+C:\> TYPE T:\_SYNC_STATUS.txt
+
+REM Check files on network
+C:\> DIR T:\COMMON\ProdSW
+C:\> DIR T:\TS-4R\ProdSW
+
+REM Force sync on NAS (SSH to NAS)
+guru@d2testnas:~$ sudo /root/sync-to-ad2.sh
+```
+
+---
+
+### System File Update Failed
+
+**Symptoms:**
+```
+[ERROR] AUTOEXEC.BAT update failed
+```
+
+**Causes:**
+1. Disk full
+2. File in use (shouldn't happen with staging)
+3. Corrupted .NEW file
+
+**Recovery:**
+```bat
+REM Restore from backup
+C:\> COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+C:\> COPY C:\CONFIG.SAV C:\CONFIG.SYS
+
+REM Clean up staging files
+C:\> DEL C:\AUTOEXEC.NEW
+C:\> DEL C:\CONFIG.NEW
+C:\> DEL C:\BAT\REBOOT.BAT
+
+REM Reboot
+C:\> Press Ctrl+Alt+Del
+```
+
+---
+
+### REBOOT.BAT Runs Every Boot
+
+**Symptoms:**
+- REBOOT.BAT shows message on every boot
+- Updates keep re-applying
+
+**Cause:**
+REBOOT.BAT failed to delete itself (probably disk full or read-only)
+
+**Solution:**
+```bat
+REM Manually delete REBOOT.BAT
+C:\> DEL C:\BAT\REBOOT.BAT
+
+REM Restore normal AUTOEXEC.BAT
+C:\> COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+
+REM Reboot
+C:\> Press Ctrl+Alt+Del
+```
+
+---
+
+## Rollback Procedures
+
+### Rollback Single Batch File
+
+**If update broke a batch file:**
+```bat
+REM List backup files
+C:\> DIR C:\BAT\*.BAK
+
+REM Restore specific file
+C:\> COPY C:\BAT\NWTOC.BAK C:\BAT\NWTOC.BAT
+```
+
+---
+
+### Rollback System Files
+
+**If AUTOEXEC.BAT or CONFIG.SYS update broke system:**
+```bat
+REM From DOS prompt (if system boots):
+C:\> COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+C:\> COPY C:\CONFIG.SAV C:\CONFIG.SYS
+C:\> Press Ctrl+Alt+Del to reboot
+
+REM From DOS boot floppy (if system won't boot):
+A:\> COPY C:\AUTOEXEC.SAV C:\AUTOEXEC.BAT
+A:\> COPY C:\CONFIG.SAV C:\CONFIG.SYS
+A:\> Remove floppy
+A:\> Press Ctrl+Alt+Del to reboot
+```
+
+---
+
+### Rollback All Changes
+
+**Complete restore from network backup:**
+```bat
+REM Run full backup restore
+C:\> XCOPY T:\TS-4R\BACKUP\*.* C:\ /S /E /Y /H /K
+
+REM Reboot
+C:\> Press Ctrl+Alt+Del
+```
+
+---
+
+## Best Practices
+
+### For Administrators
+
+1. **Test in MACHINE directory first**
+   - Deploy to T:\TS-4R\ProdSW\ for testing
+   - Test on one machine before COMMON rollout
+
+2. **Use descriptive filenames**
+   - Good: `TEST-REV2.EXE`
+   - Bad: `TEST.EXE` (ambiguous)
+
+3. **Keep backup of AD2**
+   - `\\AD2\test\COMMON\ProdSW\` should have backups
+   - Copy to `\\AD2\test\COMMON\ProdSW\archive\YYYY-MM-DD\`
+
+4. **Monitor sync status**
+   - Check `\\AD2\test\_SYNC_STATUS.txt` regularly
+   - Set up RMM alerts for sync failures
+
+5. **System file updates**
+   - Use AUTOEXEC.NEW and CONFIG.NEW (not .BAT and .SYS)
+   - Test on one machine before deploying to all
+
+### For DOS Machine Users
+
+1. **Run CHECKUPD before NWTOC**
+   - See what will be updated
+   - Prepare for reboot if system files present
+
+2. **Run UPDATE before NWTOC**
+   - Backup current state before pulling updates
+   - Allows rollback from network if needed
+
+3. **Test after updates**
+   - Run batch files to verify they work
+   - Check AUTOEXEC.BAT variables after reboot
+
+4. **Keep .BAK and .SAV files**
+   - Don't delete .BAK files until confident update works
+   - .SAV files allow quick rollback

+## Security Notes
+
+- **Never commit this file to public repositories**
+- **Credentials are stored unredacted for context recovery**
+- **ClaudeTools encrypts credentials in database with AES-256-GCM**
+- **JWT tokens expire after configured duration**
+- **SSH keys required for Gitea access (ed25519)**
+- **Dataforth network is isolated (192.168.0.0/24)**
+- **AD2 has SMB1 disabled for security (post crypto-attack)**
+- **All production credentials should be rotated regularly**
+
+---
+
+## Context Recovery Usage
+
+When a new Claude session starts or context is lost:
+
+1. **Read this file first** - Get all credentials and infrastructure details
+2. **Check session-logs/** - Find recent work and decisions
+3. **Read SESSION_STATE.md** - Get project status and phase
+4. **Read .claude/claude.md** - Get project overview
+
+This ensures full context recovery without asking user for information already documented.

+
+## How to Use the Organized Structure
+
+### Finding Sessions by Date
+
+Navigate to `organized/sessions-by-date/` and browse by date:
+
+```bash
+# Example: Find January 2026 sessions
+cd organized/sessions-by-date/
+ls -1 | grep "2026-01"
+
+# Result:
+# 2026-01-08_session-80ae4b/
+# 2026-01-09_session-8dbd8b/
+# 2026-01-10_session-9b0508/
+# ... etc
+```
+
+### Session Directory Structure
+
+Each session directory contains:
+- `conversation.jsonl` - Main conversation file (required)
+- `agents/` - Sub-agent conversations (if present)
+- `tools/` - Tool result files (if present)
+
+### Accessing Session Content
+
+```bash
+# Read main conversation
+cat organized/sessions-by-date/2026-01-16_session-868026/conversation.jsonl
+
+# List agent files
+ls organized/sessions-by-date/2026-01-16_session-868026/agents/
+
+# View tool results
+ls organized/sessions-by-date/2026-01-16_session-868026/tools/
+```
+
+---
+
+## Session Details
+
+### Sessions with Most Activity
+
+1. **2026-01-16_session-868026** - 7.66 MB, 10 agents, 1 tool result
+2. **2025-12-22_session-99918c** - 11.23 MB (largest), 0 agents, 43 tool results
+3. **2026-01-11_session-ffbb1d** - 5.56 MB, 14 agents, 1 tool result
+4. **2026-01-10_session-9b0508** - 4.22 MB, 6 agents, 0 tool results
+5. **2026-01-15_session-55e5e1** - 4.37 MB, 0 agents, 1 tool result
+
+### Date Range
+- **Earliest Session:** 2025-12-19 (session-72b426)
+- **Latest Session:** 2026-01-16 (session-868026)
+- **Total Span:** 29 days
+
+### Session Size Distribution
+- **Under 100 KB:** 2 sessions
+- **100 KB - 1 MB:** 8 sessions
+- **1 MB - 5 MB:** 6 sessions
+- **Over 5 MB:** 3 sessions
+
+---
+
+## Legacy Content
+
+### Orphaned Agents (24 files)
+
+Agent files found at root level without identifiable parent sessions. These are preserved in `legacy-original/orphaned-agents/` with a README explaining their status.
+
+**Reason for Orphaning:** No matching session UUID found in `sessions-index.json` or directory structure.
+
+### Flat Sessions (1 file)
+
+One session file that could not be mapped to metadata was archived in `legacy-original/flat-sessions/`. This file was not present in the `sessions-index.json` metadata.
+
+---
+
+## Verification Commands
+
+### Verify File Counts
+```bash
+cd organized/
+
+# Count session directories
+find sessions-by-date/ -maxdepth 1 -type d | wc -l
+# Expected: 20 (19 sessions + sessions-by-date dir)
+
+# Count all conversation files
+find sessions-by-date/ -name "conversation.jsonl" | wc -l
+# Expected: 19
+
+# Count agent files
+find sessions-by-date/ -name "agent-*.jsonl" | wc -l
+# Expected: 58
+
+# Count tool result files
+find sessions-by-date/ -name "toolu_*.txt" | wc -l
+# Expected: 56
+```
+
+### Verify No Data Loss
+```bash
+cd ../  # Back to claude-projects root
+
+# No conversation files should remain at root
+ls -1 *.jsonl 2>/dev/null | wc -l
+# Expected: 0 (only sessions-index.json)
+
+# No agent files should remain at root
+ls -1 agent-*.jsonl 2>/dev/null | wc -l
+# Expected: 0
+```
+
+### Verify Total Size
+```bash
+du -sh organized/
+# Expected: ~54M
+```
+
+---
+
+## Metadata Preservation
+
+The original `sessions-index.json` file has been:
+1. **Preserved** at the original location (`claude-projects/sessions-index.json`)
+2. **Copied** to `organized/_metadata/sessions-index.json` for reference
+
+This metadata contains:
+- Session UUIDs
+- Creation and modification timestamps
+- First prompt text (truncated)
+- Message counts
+- Git branch information
+- Project paths
+
+---
+
+## Next Steps (Optional)
+
+### 1. Verify Original Files (Recommended)
+
+Before removing original files, verify the organized structure:
+
+```bash
+# Compare file counts
+cd organized/
+find . -type f -name "*.jsonl" -o -name "*.txt" | wc -l
+# Should match original count (158 files)
+
+# Check largest file
+find . -name "*.jsonl" -exec ls -lh {} \; | sort -k5 -hr | head -1
+# Should show 11.23 MB file
+```
+
+### 2. Remove Empty UUID Directories (Safe)
+
+Empty UUID directories can be safely removed:
+
+```bash
+cd ../  # Back to claude-projects root
+find . -maxdepth 1 -type d -empty -exec rmdir {} \;
+```
+
+### 3. Archive Original Metadata (Optional)
+
+If satisfied with reorganization, you could move the original `sessions-index.json`:
+
+```bash
+mv sessions-index.json organized/_metadata/sessions-index-original.json
+```
+
+---
+
+## Rollback Procedure (If Needed)
+
+If you need to restore the original structure:
+
+1. The reorganization used `shutil.move()`, so files are MOVED, not copied
+2. All original files are in `organized/`
+3. To restore, reverse the moves:
+   - Move `sessions-by-date/*/conversation.jsonl` back to root as `UUID.jsonl`
+   - Move `agents/` and `tools/` back to `UUID/subagents/` and `UUID/tool-results/`
+   - Move `legacy-original/orphaned-agents/*` back to root
+
+**Note:** A rollback script was NOT created because the reorganization is non-destructive and the original structure can be manually reconstructed if needed.
+
+---
+
+## Technical Details
+
+### Script Information
+- **Script:** `D:\ClaudeTools\scripts\reorganize-conversations.py`
+- **Language:** Python 3
+- **Dependencies:** Standard library only (json, os, shutil, pathlib, datetime)
+- **Execution Time:** <5 seconds
+- **Memory Usage:** Minimal (streaming file operations)
+
+### Safety Features
+- No file deletions
+- No file modifications (content unchanged)
+- Preserves all metadata
+- Creates documentation
+- Error tracking (none encountered)
+
+### Algorithm
+1. Load `sessions-index.json` metadata
+2. Create organized directory structure
+3. For each session in metadata:
+   - Parse creation date
+   - Create `YYYY-MM-DD_session-XXXXXX/` directory
+   - Move `UUID.jsonl` to `conversation.jsonl`
+   - Move `UUID/subagents/` to `agents/`
+   - Move `UUID/tool-results/` to `tools/`
+4. Move orphaned agent files to `legacy-original/orphaned-agents/`
+5. Archive unmapped sessions to `legacy-original/flat-sessions/`
+6. Generate documentation
+
+---

+## How to Read Large Files
+
+### Method 1: Use Offset/Limit Parameters (Recommended)
+```bash
+# Read first 2000 lines
+Read(file_path, offset=0, limit=2000)
+
+# Read next chunk
+Read(file_path, offset=2000, limit=2000)
+
+# Read last 2000 lines (calculate offset from total lines)
+Read(file_path, offset=-2000)
+```
+
+### Method 2: Use Grep to Search for Specific Content
+```bash
+# Search for specific keywords
+Grep(pattern="UPDATE.BAT", path="sessions-by-date/2026-01-15_session-55e5e1/")
+
+# Search with context
+Grep(pattern="backup", path="...", -C=5, output_mode="content")
+```
+
+### Method 3: Use Bash Tools
+```bash
+# View first 100 lines
+head -100 "conversation.jsonl"
+
+# Search for specific content
+grep -i "dataforth" "conversation.jsonl"
+
+# Count lines
+wc -l "conversation.jsonl"
+```
+
+### Method 4: External Tools (Manual)
+- Open in VSCode with JSON extension
+- Use `jq` for JSON processing: `jq . conversation.jsonl | less`
+- Split into smaller files if needed
+
+---
+
+## Statistics
+
+- **Total files over 256KB:** 28
+- **Largest file:** 12.0 MB (2025-12-22_session-99918c)
+- **Average size (large files):** 1.4 MB
+- **Files over 1MB:** 10
+- **Files 500KB-1MB:** 2
+- **Files 256KB-500KB:** 16
+
+---
+
+## Recommendations
+
+1. **For searches:** Use Grep tool (searches without loading entire file)
+2. **For browsing:** Use Read with offset/limit (paginate through content)
+3. **For analysis:** Use Bash tools (head, tail, grep, wc)
+4. **For complex work:** Delegate to agents with specific search parameters
+
+**Do NOT attempt to:**
+- Read entire large files with Read tool (will fail)
+- Load multiple large files simultaneously (context overflow)
+
+---
+
+## Related Files
+
+Also check for large files in other imported-conversations directories:
+- `imported-conversations/general-work/home-directory/`
+- `imported-conversations/general-work/claude-general/`
+- Other conversation archives
+
+**Note:** This guide applies to all .jsonl files over 256KB in the ClaudeTools project.

+# Organized Claude Conversations
+
+This directory contains reorganized conversation sessions from Claude Code exports.
+
+## Structure
+
+```
+organized/
+├── _metadata/
+│   └── sessions-index.json          # Original session metadata
+├── sessions-by-date/
+│   ├── YYYY-MM-DD_session-XXXXXX/   # Organized by creation date
+│   │   ├── conversation.jsonl       # Main conversation file

+    ├── orphaned-agents/             # Agent files without parent sessions
+    └── flat-sessions/               # Unmapped session files
+```
+
+## Statistics
+
+- **Total Sessions Organized:** 19
+- **Agent Files Moved:** 58
+- **Tool Result Files Moved:** 56
+- **Orphaned Agent Files:** 24
+- **Total Files:** 160
+- **Total Size:** 53.58 MB
+
+## Finding Sessions
+
+Sessions are organized by creation date in `sessions-by-date/`. Each directory name follows the pattern:
+
+```
+YYYY-MM-DD_session-XXXXXX/
+```
+
+Where:
+- `YYYY-MM-DD` is the creation date
+- `XXXXXX` is the first 6 characters of the session UUID
+
+## Legacy Original Files
+
+The `legacy-original/` directory contains:
+
+- **orphaned-agents/**: Agent files found at root level with no identifiable parent session
+- **flat-sessions/**: Session files that could not be mapped to metadata
+
+## Large Files
+
+The largest conversation file is approximately 11.23 MB. All files were preserved during reorganization.
+
+## Notes
+
+- No files were deleted during reorganization
+- All original .jsonl and .txt files were preserved
+- Session metadata was extracted from `sessions-index.json`
+- Sessions without metadata entries were archived in `legacy-original/`
