+# eDNC Special Character Fix - Claude Code Instructions
+
+## Project Overview
+
+PowerShell utility that monitors DNC folders and removes invalid special characters (0xFF) from .pun files in real-time. Deployed to CNC workstations via network share.
+
+## Technology Stack
+
+- **Language:** PowerShell 5.1+
+- **Deployment:** Network share (S:\DT\cameron\eDNC-Fix\) → Local (C:\eDNC-Fix\)
+- **Logging:** ShopDB API (http://geitshopdb/api.asp)
+- **Version Control:** Gitea (localhost:3000/cproudlock/edncfix)
+
+## IMPORTANT: After Making Changes
+
+**Always do the following after any code changes:**
+
+1. **Update version numbers** in ALL of these files:
+   - `eDNC-SpecialCharFix.ps1` - `$ScriptVersion` variable (line ~81)
+   - `eDNC-SpecialCharFix.ps1` - `.NOTES` section Version field
+   - `version.ini` - `Version=x.x.x`
+   - `README.md` - Version History table
+
+2. **Commit and push to Gitea:**
+   ```bash
+   cd /home/camp/projects/powershell/edncfix
+   git add -A
+   git commit -m "vX.X.X: Description of changes"
+   git push
+   ```
+
+3. **Version format:** Use semantic versioning (MAJOR.MINOR.PATCH)
+   - MAJOR: Breaking changes
+   - MINOR: New features
+   - PATCH: Bug fixes
+
+## File Structure
+
+```
+/home/camp/projects/powershell/edncfix/
+├── eDNC-SpecialCharFix.ps1   # Main script
+├── Run-eDNCFix.bat           # Manual launcher (auto-elevates)
+├── Install-ScheduledTask.ps1 # Creates Windows scheduled task
+├── Deploy.bat                # Copies from S: to C:\eDNC-Fix\
+├── version.ini               # Version file for auto-updates

+## Configuration (Hardcoded)
+
+| Setting | Value | Location |
+|---------|-------|----------|
+| Watch Folder | `C:\Dnc_Files\Q` | eDNC-SpecialCharFix.ps1 |
+| File Filter | `*.pun` | eDNC-SpecialCharFix.ps1 |
+| Update Source | `S:\DT\cameron\eDNC-Fix` | eDNC-SpecialCharFix.ps1 |
+| API URL | `http://geitshopdb/api.asp` | eDNC-SpecialCharFix.ps1 |
+| Update Interval | 300 seconds (5 min) | eDNC-SpecialCharFix.ps1 |
+
+## ShopDB API Integration
+
+The script logs events to ShopDB via the API. Reference the ShopDB API documentation at:
+- **ShopDB Project:** `/home/camp/projects/windows/shopdb/`
+- **API File:** `/home/camp/projects/windows/shopdb/api.asp`
+- **Standards Doc:** `/home/camp/projects/windows/shopdb/docs/STANDARDS.md`
+
+### API Endpoint: logDNCEvent
+
+**Method:** POST
+**URL:** `http://geitshopdb/api.asp`
+
+**Parameters:**
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| action | string | Yes | Must be "logDNCEvent" |
+| hostname | string | Yes | PC hostname |
+| eventType | string | Yes | Event type: started, cleaned, ok, failed, error, stopped |
+| filename | string | No | File being processed |
+| bytesRemoved | int | No | Number of bytes removed |
+| version | string | No | Script version |
+| message | string | No | Additional details |
+| watchFolder | string | No | Folder being watched |
+| fileFilter | string | No | File filter pattern |
+
+**Database Tables:**
+- `ednc_logs` - Individual event log entries
+- `ednc_installations` - Per-hostname installation tracking
+
+### API Endpoint: getDNCStats
+
+**Method:** GET
+**URL:** `http://geitshopdb/api.asp?action=getDNCStats`
+
+Returns JSON with all eDNC installations and their stats.
+
+## Deployment Workflow
+
+1. **Development:** Edit files in `/home/camp/projects/powershell/edncfix/`
+2. **Update versions:** Bump all version numbers
+3. **Commit:** Push to Gitea
+4. **Stage:** Copy files to `S:\DT\cameron\eDNC-Fix\`
+5. **Deploy:** On target PC, run `Deploy.bat` from S: drive
+6. **Install:** Run `Install-ScheduledTask.ps1` as Admin
+
+## Auto-Update Mechanism
+
+Running instances check `S:\DT\cameron\eDNC-Fix\version.ini` every 5 minutes.
+If a newer version is found, they automatically:
+1. Copy new files from S: to C:\eDNC-Fix\
+2. Restart themselves
+
+**To deploy an update to all PCs:**
+1. Update version.ini with new version number
+2. Copy updated files to S:\DT\cameron\eDNC-Fix\
+3. Wait up to 5 minutes for auto-update
+
+## Quick Reference
+
+### Test API endpoint:
+```bash
+curl -X POST http://192.168.122.151:8080/api.asp \
+  -d "action=logDNCEvent&hostname=TESTPC&eventType=started&version=1.5.0"
+```
+
+### Check installations:
+```bash
+curl "http://192.168.122.151:8080/api.asp?action=getDNCStats"
+```
+
+### View logs in database:
+```sql
+SELECT * FROM ednc_logs ORDER BY created DESC LIMIT 20;
+SELECT * FROM ednc_installations;
+```
