🔧 AUTO-APPROVED OPERATIONS

The following operations are auto-approved and do not require user confirmation:

  • Read: All file read operations (Read(*))
  • Glob: All file pattern matching (Glob(*))
  • Grep: All content searching (Grep(*))

These permissions are configured in ~/.claude/settings.json.

⚠️ SAFETY GUIDELINES

ALWAYS WARN THE USER before performing any action that could:

  • Overwrite existing files (use ls or cat to check first)
  • Overwrite credentials, API keys, or secrets
  • Delete data or files
  • Modify production configurations
  • Run destructive git commands (force push, hard reset, etc.)
  • Drop databases or truncate tables

Best practices:

  • Before writing to a file, check if it exists and show its contents
  • Use >> (append) instead of > (overwrite) for credential files
  • Create backups before modifying critical configs (e.g., cp file file.backup)
  • Ask for confirmation before irreversible actions

Sudo commands:

  • NEVER run sudo commands directly - the Bash tool doesn't support interactive input
  • Instead, provide the user with the exact sudo command they need to run in their terminal
  • Format the command clearly in a code block for easy copy-paste
  • After user runs the sudo command, continue with the workflow
  • Alternative: If user has recently run sudo (within ~15 min), subsequent sudo commands may not require password

🔑 ACCESS & CREDENTIALS

Version Control & Code Hosting

  • Gitea: Self-hosted at gitea.jeffemmett.com - PRIMARY repository

    • Push here FIRST, then mirror to GitHub
    • Private repos and source of truth
    • SSH Key: ~/.ssh/gitea_ed25519 (private), ~/.ssh/gitea_ed25519.pub (public)
    • Public Key: ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIIE2+2UZElEYptgZ9GFs2CXW0PIA57BfQcU9vlyV6fz4 gitea@jeffemmett.com
    • Gitea CLI (tea): ✅ Installed at ~/bin/tea (added to PATH)

  • GitHub: Public mirror and collaboration

    • Receives pushes from Gitea via mirror sync
    • Token: (REDACTED-GITHUB-TOKEN)
    • SSH Key: ~/.ssh/github_deploy_key (private), ~/.ssh/github_deploy_key.pub (public)
    • GitHub CLI (gh): ✅ Installed and available for PR/issue management

Git Workflow

Two-way sync between Gitea and GitHub:

Gitea-Primary Repos (Default):

  1. Develop locally in /home/jeffe/Github/
  2. Commit and push to Gitea first
  3. Gitea automatically mirrors TO GitHub (built-in push mirror)
  4. GitHub used for public collaboration and visibility

GitHub-Primary Repos (Mirror Repos): For repos where GitHub is source of truth (v0.dev exports, client collabs):

  1. Push to GitHub
  2. Deploy webhook pulls from GitHub and deploys
  3. Webhook triggers Gitea to sync FROM GitHub

🔀 DEV BRANCH WORKFLOW (MANDATORY)

CRITICAL: All development work on canvas-website (and other active projects) MUST use a dev branch.

Branch Strategy

main (production)
  └── dev (integration/staging)
        └── feature/* (optional feature branches)

Development Rules

  1. ALWAYS work on the dev branch for new features and changes:

    cd /home/jeffe/Github/canvas-website
git checkout dev
git pull origin dev

  2. After completing a feature, push to dev:

    git add .
git commit -m "feat: description of changes"
git push origin dev

  3. Update backlog task immediately after pushing:

    backlog task edit <task-id> --status "Done" --append-notes "Pushed to dev branch"

  4. NEVER push directly to main - main is for tested, verified features only

  5. Merge dev → main manually when features are verified working:

    git checkout main
git pull origin main
git merge dev
git push origin main
git checkout dev  # Return to dev for continued work

Complete Feature Deployment Checklist

  • Work on dev branch (not main)
  • Test locally before committing
  • Commit with descriptive message
  • Push to dev branch on Gitea
  • Update backlog task status to "Done"
  • Add notes to backlog task about what was implemented
  • (Later) When verified working: merge dev → main manually

Why This Matters

  • Protects production: main branch always has known-working code
  • Enables testing: dev branch can be deployed to staging for verification
  • Clean history: main only gets complete, tested features
  • Easy rollback: if dev breaks, main is still stable

🚀 Traefik Reverse Proxy (Central Routing)

All HTTP services on Netcup RS 8000 route through Traefik for automatic service discovery.

Architecture:

Internet → Cloudflare Tunnel → Traefik (:80/:443) → Docker Services
                                    │
                                    ├── gitea.jeffemmett.com → gitea:3000
                                    ├── mycofi.earth → mycofi:3000
                                    ├── games.jeffemmett.com → games:80
                                    └── [auto-discovered via Docker labels]

Location: /root/traefik/ on Netcup RS 8000

Adding a New Service:

# In your docker-compose.yml, add these labels:
services:
  myapp:
    image: myapp:latest
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.myapp.rule=Host(`myapp.jeffemmett.com`)"
      - "traefik.http.services.myapp.loadbalancer.server.port=3000"
    networks:
      - traefik-public
networks:
  traefik-public:
    external: true

Traefik Dashboard: http://159.195.32.209:8888 (internal only)

SSH Git Access:

  • SSH goes direct (not through Traefik): git.jeffemmett.com:223 → 159.195.32.209:223
  • Web UI goes through Traefik: gitea.jeffemmett.com → Traefik → gitea:3000

☁️ Cloudflare Tunnel Configuration

Location: /root/cloudflared/ on Netcup RS 8000

The tunnel uses a token-based configuration managed via Cloudflare Zero Trust Dashboard. All public hostnames should point to http://localhost:80 (Traefik), which routes based on Host header.

Managed hostnames:

  • gitea.jeffemmett.com → Traefik → Gitea
  • photos.jeffemmett.com → Traefik → Immich
  • movies.jeffemmett.com → Traefik → Jellyfin
  • search.jeffemmett.com → Traefik → Semantic Search
  • mycofi.earth → Traefik → MycoFi
  • games.jeffemmett.com → Traefik → Games Platform
  • decolonizeti.me → Traefik → Decolonize Time

Tunnel ID: a838e9dc-0af5-4212-8af2-6864eb15e1b5 Tunnel CNAME Target: a838e9dc-0af5-4212-8af2-6864eb15e1b5.cfargotunnel.com

To deploy a new website/service:

  1. Dockerize the project with Traefik labels in docker-compose.yml:

    services:
  myapp:
    build: .
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.myapp.rule=Host(`mydomain.com`) || Host(`www.mydomain.com`)"
      - "traefik.http.services.myapp.loadbalancer.server.port=3000"
    networks:
      - traefik-public
networks:
  traefik-public:
    external: true

  2. Deploy to Netcup:

    ssh netcup "cd /opt/websites && git clone <repo-url>"
ssh netcup "cd /opt/websites/<project> && docker compose up -d --build"

  3. Add hostname to tunnel config (/root/cloudflared/config.yml):

    - hostname: mydomain.com
  service: http://localhost:80
- hostname: www.mydomain.com
  service: http://localhost:80

    Then restart: ssh netcup "docker restart cloudflared"

  4. Configure DNS in Cloudflare dashboard (CRITICAL - prevents 525 SSL errors):

    • Go to Cloudflare Dashboard → select domain → DNS → Records
    • Delete any existing A/AAAA records for @ and www
    • Add CNAME records:
      Type Name Target Proxy
      CNAME @ a838e9dc-0af5-4212-8af2-6864eb15e1b5.cfargotunnel.com Proxied ✓
      CNAME www a838e9dc-0af5-4212-8af2-6864eb15e1b5.cfargotunnel.com Proxied ✓

API Credentials (on Netcup at ~/.cloudflare*):

  • CLOUDFLARE_API_TOKEN - Zone read access only
  • CLOUDFLARE_TUNNEL_TOKEN - Tunnel management only
  • See API Keys & Services section above for Domain Management Token (required for DNS automation)

🔄 Auto-Deploy Webhook System

Location: /opt/deploy-webhook/ on Netcup RS 8000 Endpoint: https://deploy.jeffemmett.com/deploy/<repo-name> Secret: gitea-deploy-secret-2025

Pushes to Gitea automatically trigger rebuilds. The webhook receiver:

  1. Validates HMAC signature from Gitea
  2. Runs git pull && docker compose up -d --build
  3. Returns build status

Adding a new repo to auto-deploy:

  1. Add entry to /opt/deploy-webhook/webhook.py REPOS dict
  2. Restart: ssh netcup "cd /opt/deploy-webhook && docker compose up -d --build"
  3. Add Gitea webhook: 
    curl -X POST "https://gitea.jeffemmett.com/api/v1/repos/jeffemmett/<repo>/hooks" \
  -H "Authorization: token <gitea-token>" \
  -H "Content-Type: application/json" \
  -d '{"type":"gitea","active":true,"events":["push"],"config":{"url":"https://deploy.jeffemmett.com/deploy/<repo>","content_type":"json","secret":"gitea-deploy-secret-2025"}}'

Currently auto-deploying:

  • decolonize-time-website → /opt/websites/decolonize-time-website
  • mycofi-earth-website → /opt/websites/mycofi-earth-website
  • games-platform → /opt/apps/games-platform

🤖 AI ORCHESTRATION ARCHITECTURE

Smart Routing Strategy

All AI requests go through intelligent orchestration layer on RS 8000:

Routing Logic:

  • Text/Code (70-80% of workload): Always local RS 8000 CPU (Ollama) → FREE
  • Images - Low Priority: RS 8000 CPU (SD 1.5/2.1) → FREE but slow (~60s)
  • Images - High Priority: RunPod GPU (SDXL/SD3) → $0.02/image, fast
  • Video Generation: Always RunPod GPU → $0.50/video (only option)
  • Training/Fine-tuning: RunPod GPU on-demand

Queue System:

  • Redis-based queues: text, image, code, video
  • Priority-based routing (low/normal/high)
  • Worker pools scale based on load
  • Cost tracking per job, per user

Cost Optimization:

  • Target: $90-120/mo (vs $136-236/mo current)
  • Savings: $552-1,392/year
  • 70-80% of workload FREE (local CPU)
  • GPU only when needed (serverless = no idle costs)

from orchestrator_client import AIOrchestrator
ai = AIOrchestrator("http://rs8000-ip:8000")

# Automatically routes based on priority & model
result = await ai.generate_text(prompt, priority="low")  # → FREE CPU
result = await ai.generate_image(prompt, priority="high") # → RunPod GPU

> 10,000 images OR > 500 videos + training Netcup RS 4000 vGPU 14 $285 fixed
Unpredictable/bursty workloads RunPod Serverless Variable

Migration Strategy

Phase 1: Immediate (Before July 7, 2025)

Decision Point: Secure Netcup vGPU Early Access?

  • Monitor actual GPU usage for 2-4 weeks
  • Calculate average monthly image/video generation
  • If consistently > 5,000 images/mo → Consider RS 2000 vGPU 7
  • If consistently > 10,000 images/mo → Consider RS 4000 vGPU 14
  • ACTION: Redeem early access code if usage justifies fixed GPU

Monitoring & Review Schedule

  • Weekly: Review RunPod spend dashboard
  • Monthly: Calculate total GPU costs, compare to vGPU break-even
  • Quarterly: Re-evaluate architecture, consider plan changes
  • Annually: Full infrastructure cost audit

Action Items

  • URGENT: Decide on Netcup vGPU early access before July 7, 2025
  • Set up GPU usage tracking in orchestrator
  • Create Grafana dashboard for cost monitoring
  • Test Wan2.1 I2V 14B model on vGPU 14 (if acquired)
  • Document migration runbook for vGPU setup
  • Complete DigitalOcean deprecation (separate from GPU decision)

📁 PROJECT PORTFOLIO STRUCTURE

Repository Organization

  • Location: /home/jeffe/Github/
  • Primary Flow: Gitea (source of truth) → GitHub (public mirror)
  • Containerization: ALL repos must be Dockerized with optimized production containers

🎯 MAIN PROJECT: canvas-website

Location: /home/jeffe/Github/canvas-website Description: Collaborative canvas deployment - the integration hub where all tools come together

  • Tldraw-based collaborative canvas platform
  • Integrates Hyperindex, rSpace, MycoFi, and other tools
  • Real-time collaboration features
  • Deployed on RS 8000 in Docker
  • Uses AI orchestrator for intelligent features

Project Categories

AI & Infrastructure:

  • AI Orchestrator (smart routing between RS 8000 & RunPod)
  • Model hosting & fine-tuning pipelines
  • Cost optimization & monitoring dashboards

Web Applications & Sites:

  • canvas-website: Main collaborative canvas (integration hub)
  • All deployed in Docker containers on RS 8000
  • Cloudflare Workers for edge functions (Hyperindex)
  • Static sites + dynamic backends containerized

Supporting Projects:

  • Hyperindex: Tldraw canvas integration (Cloudflare stack) - integrates into canvas-website
  • rSpace: Real-time collaboration platform - integrates into canvas-website
  • MycoFi: DeFi/Web3 project - integrates into canvas-website
  • Canvas-related tools: Knowledge graph & visualization components

Deployment Strategy

  1. Development: Local WSL2 environment (/home/jeffe/Github/)
  2. Version Control: Push to Gitea FIRST → Auto-mirror to GitHub
  3. Containerization: Build optimized Docker images with Traefik labels
  4. Deployment: Deploy to RS 8000 via Docker Compose (join traefik-public network)
  5. Routing: Traefik auto-discovers service via labels, no config changes needed
  6. DNS: Add hostname to Cloudflare tunnel (if new domain) or it just works (existing domains)
  7. AI Integration: Connect to local orchestrator API
  8. Monitoring: Grafana dashboards for all services

Infrastructure Philosophy

  • Self-hosted first: Own your infrastructure (RS 8000 + Gitea)
  • Cloud for edge cases: Cloudflare (edge), RunPod (GPU burst)
  • Cost-optimized: Local CPU for 70-80% of workload
  • Dockerized everything: Reproducible, scalable, maintainable
  • Smart orchestration: Right compute for the right job
  • can you make sure you are runing the hf download for a non deprecated version? After that, you can proceed with Image-to-Video 14B 720p (RECOMMENDED) huggingface-cli download Wan-AI/Wan2.1-I2V-14B-720P
    --include "*.safetensors"
    --local-dir models/diffusion_models/wan2.1_i2v_14b

🕸️ HYPERINDEX PROJECT - TOP PRIORITY

Location: /home/jeffe/Github/hyperindex-system/

When user is ready to work on the hyperindexing system:

  1. Reference HYPERINDEX_PROJECT.md for complete architecture and implementation details
  2. Follow HYPERINDEX_TODO.md for step-by-step checklist
  3. Start with Phase 1 (Database & Core Types), then proceed sequentially through Phase 5
  4. This is a tldraw canvas integration project using Cloudflare Workers, D1, R2, and Durable Objects
  5. Creates a "living, mycelial network" of web discoveries that spawn on the canvas in real-time

📋 BACKLOG.MD - UNIFIED TASK MANAGEMENT

All projects use Backlog.md for task tracking. Tasks are managed as markdown files and can be viewed at backlog.jeffemmett.com for a unified cross-project view.

MCP Integration

Backlog.md is integrated via MCP server. Available tools:

  • backlog.task_create - Create new tasks
  • backlog.task_list - List tasks with filters
  • backlog.task_update - Update task status/details
  • backlog.task_view - View task details
  • backlog.search - Search across tasks, docs, decisions

Task Lifecycle Workflow

CRITICAL: Claude agents MUST follow this workflow for ALL development tasks:

1. Task Discovery (Before Starting Work)

# Check if task already exists
backlog search "<task description>" --plain

# List current tasks
backlog task list --plain

2. Task Creation (If Not Exists)

# Create task with full details
backlog task create "Task Title" \
  --desc "Detailed description" \
  --priority high \
  --status "To Do"

3. Starting Work (Move to In Progress)

# Update status when starting
backlog task edit <task-id> --status "In Progress"

4. During Development (Update Notes)

# Append progress notes
backlog task edit <task-id> --append-notes "Completed X, working on Y"

# Update acceptance criteria
backlog task edit <task-id> --check-ac 1

5. Completion (Move to Done)

# Mark complete when finished
backlog task edit <task-id> --status "Done"

Project Initialization

When starting work in a new repository that doesn't have backlog:

cd /path/to/repo
backlog init "Project Name" --integration-mode mcp --defaults

This creates the backlog/ directory structure:

backlog/
├── config.yml          # Project configuration
├── tasks/              # Active tasks
├── completed/          # Finished tasks
├── drafts/             # Draft tasks
├── docs/               # Project documentation
├── decisions/          # Architecture decision records
└── archive/            # Archived tasks

Task File Format

Tasks are markdown files with YAML frontmatter:

---
id: task-001
title: Feature implementation
status: In Progress
assignee: [@claude]
created_date: '2025-12-03 14:30'
labels: [feature, backend]
priority: high
dependencies: [task-002]
---

Agent Behavior Requirements

When Claude starts working on ANY task:

  1. Check for existing backlog in the repo:

    ls backlog/config.yml 2>/dev/null || echo "Backlog not initialized"

  2. If backlog exists, search for related tasks:

    backlog search "<relevant keywords>" --plain

  3. Create or update task before writing code:

    # If new task needed:
backlog task create "Task title" --status "In Progress"

# If task exists:
backlog task edit <id> --status "In Progress"

  4. Update task on completion:

    backlog task edit <id> --status "Done" --append-notes "Implementation complete"

  5. Never leave tasks in "In Progress" when stopping work - either complete them or add notes explaining blockers.

Backlog CLI Quick Reference

Task Operations

Action Command
View task backlog task 42 --plain
List tasks backlog task list --plain
Search tasks backlog search "topic" --plain
Filter by status backlog task list -s "In Progress" --plain
Create task backlog task create "Title" -d "Description" --ac "Criterion 1"
Edit task backlog task edit 42 -t "New Title" -s "In Progress"
Assign task backlog task edit 42 -a @claude

Acceptance Criteria Management

Action Command
Add AC backlog task edit 42 --ac "New criterion"
Check AC #1 backlog task edit 42 --check-ac 1
Check multiple backlog task edit 42 --check-ac 1 --check-ac 2
Uncheck AC backlog task edit 42 --uncheck-ac 1
Remove AC backlog task edit 42 --remove-ac 2

Multi-line Input (Description/Plan/Notes)

The CLI preserves input literally. Use shell-specific syntax for real newlines:

# Bash/Zsh (ANSI-C quoting)
backlog task edit 42 --notes $'Line1\nLine2\nLine3'
backlog task edit 42 --plan $'1. Step one\n2. Step two'

# POSIX portable
backlog task edit 42 --notes "$(printf 'Line1\nLine2')"

# Append notes progressively
backlog task edit 42 --append-notes $'- Completed X\n- Working on Y'

Definition of Done (DoD)

A task is Done only when ALL of these are complete:

Via CLI:

  1. All acceptance criteria checked: --check-ac <index> for each
  2. Implementation notes added: --notes "..." or --append-notes "..."
  3. Status set to Done: -s Done

Via Code/Testing: 4. Tests pass (run test suite and linting) 5. Documentation updated if needed 6. Code self-reviewed 7. No regressions

NEVER mark a task as Done without completing ALL items above.

🔧 TROUBLESHOOTING

tmux "server exited unexpectedly"

This error occurs when a stale socket file exists from a crashed tmux server.

Fix:

rm -f /tmp/tmux-$(id -u)/default

Then start a new session normally with tmux or tmux new -s <name>.
