- Clone of github.com/fluxerapp/fluxer (official upstream)
- SELF_HOSTING.md: full VM rebuild procedure, architecture overview,
  service reference, step-by-step setup, troubleshooting, seattle reference
- dev/.env.example: all env vars with secrets redacted and generation instructions
- dev/livekit.yaml: LiveKit config template with placeholder keys
- fluxer-seattle/: existing seattle deployment setup scripts

+# Fluxer Branch Management Guide
+
+## Current Setup
+- **Branch**: `canary` (development/testing branch)
+- **Repository**: https://git.vish.gg/Vish/homelab.git
+- **Purpose**: Contains human verification fixes and custom configurations
+
+## Why Canary Branch?
+- `canary` is Fluxer's development branch - perfect for fixes and testing
+- Keeps your modifications separate from stable releases
+- Allows easy updates without breaking working configurations
+- Industry standard for development/testing deployments
+
+## Updating Your Branch
+
+### 1. Update Your Custom Fixes
+```bash
+cd fluxer
+git checkout canary
+git pull origin canary
+```
+
+### 2. Get Upstream Fluxer Updates (Optional)
+```bash
+# Add upstream if not already added
+git remote add upstream https://github.com/fluxerapp/fluxer.git
+
+# Fetch and merge upstream changes
+git fetch upstream
+git merge upstream/canary
+
+# Push merged changes back to your repo
+git push origin canary
+```
+
+### 3. Update Just Your Fixes
+```bash
+# Make your changes to fix files
+# Then commit and push
+git add .
+git commit -m "update: improve human verification fixes"
+git push origin canary
+```
+
+## Branch Safety
+
+### ✅ Safe Operations
+- Working on `canary` branch
+- Pulling from your own `origin/canary`
+- Making fixes to verification/rate limiting
+- Testing new configurations
+
+### ⚠️ Be Careful With
+- Merging upstream changes (test first)
+- Major version updates from upstream
+- Changing core database schemas
+
+### 🚫 Avoid
+- Working directly on `main` branch
+- Force pushing (`git push --force`)
+- Deleting the branch accidentally
+
+## Quick Commands Reference
+
+```bash
+# Check current branch
+git branch
+
+# Switch to canary (if not already there)
+git checkout canary
+
+# See what's changed
+git status
+git log --oneline -10
+
+# Update from your repo
+git pull origin canary
+
+# Update one-liner URLs after changes
+# Complete setup: https://git.vish.gg/Vish/homelab/raw/branch/canary/fluxer/complete-setup.sh
+# Quick fix: https://git.vish.gg/Vish/homelab/raw/branch/canary/fluxer/fix-human-verification.sh
+```
+
+## Deployment Strategy
+
+1. **Development**: Work on `canary` branch (current setup)
+2. **Testing**: Use the one-liner installers to test
+3. **Production**: Deploy from `canary` when stable
+4. **Rollback**: Keep previous working commits tagged
+
+## 🎉 Branch Lifecycle Complete - Mission Accomplished!
+
+### ✅ Canary Branch Successfully Merged and Removed
+
+The `canary` branch has completed its mission and been safely removed:
+
+1. **✅ Development Complete**: All human verification fixes developed and tested
+2. **✅ Integration Complete**: Fixes moved to production structure in `homelab/deployments/fluxer-seattle/`
+3. **✅ Production Ready**: One-liner installers created and tested
+4. **✅ Cleanup Complete**: Canary branch merged and safely removed (February 2025)
+
+### 🚀 Production URLs (Now Live)
+- **Complete Setup**: `curl -sSL https://git.vish.gg/Vish/homelab/raw/branch/main/deployments/fluxer-seattle/complete-setup.sh | bash`
+- **Quick Fix**: `curl -sSL https://git.vish.gg/Vish/homelab/raw/branch/main/deployments/fluxer-seattle/fix-human-verification.sh | bash`
+
+### 🏗️ New Deployment Structure
+All fixes are now permanently available in the main branch under:
+```
+homelab/deployments/fluxer-seattle/
+├── complete-setup.sh          # Full installation
+├── fix-human-verification.sh  # Fix existing installations  
+├── AuthRateLimitConfig.ts     # Updated rate limits
+└── README.md                  # Comprehensive documentation
+```
+
+**The human verification nightmare is officially over! 🌊**
