🎯 ZeroLagHub - Complete Current State (December 7, 2025)

Last Updated: December 7, 2025 (End of Day)
Version: Strategic + Tactical Integration
Status: 85% Launch Ready + Active Development Sprint

📊 Executive Summary

Platform Status: OPERATIONAL ✅

Core Achievement: All 6 Minecraft variants provisioning successfully via Go agent with self-repair verification system.

Launch Readiness: 85% complete

  • ✅ Provisioning pipeline: 100% operational
  • ✅ All MC variants: Working (Vanilla, Paper, Purpur, Fabric, Forge, NeoForge)
  • ✅ DNS automation: Cloudflare + Technitium + Velocity
  • ⚠️ UX features: Need WebSocket, crash protection, disk monitoring
  • 📋 Dev containers: Spec defined, implementation starting

Current Sprint: Dev containers → EdgeState → DNS reliability → Reconciliation

🎯 Two Perspectives on Current State

🏗️ Strategic View (Business/Architecture)

  • Launch decision point: NOW vs +1 week vs +1 month
  • 9.75x revenue multiplier validated
  • Developer-to-player pipeline is differentiator
  • LXC 20-30% performance advantage over Docker

⚙️ Tactical View (Engineering/Implementation)

  • All variants DONE ✅
  • Directory normalization IN PROGRESS 🟧
  • Dev containers NEXT PRIORITY 🟦
  • EdgeState + DNS reliability on deck 🟦

Integration: Strategic launch readiness aligns with tactical sprint completion

🟩 Engineering Kanban (Today's State)

DONE ✅

  • 🟧 Final cleanup of verify.go edge cases
  • 🟧 Reduction of false negatives in READY detection

TODO – NEXT PRIORITY 🟦

  1. 🟦 Dev container provisioning spec
  2. 🟦 Dev container template creation (6000-series)
  3. 🟦 Dev provisioning flow (Agent + API)
  4. 🟦 EdgeState schema (record ID tracking)
  5. 🟦 DNS deletion reliability (use record IDs)
  6. 🟦 Velocity deregistration correctness
  7. 🟦 Reconcile job (hourly or on-demand)

BACKLOG 🟥

  • 🟥 WebSocket push events (Agent → API) [Launch Critical]
  • 🟥 Installer progress reporting (%) [UX Enhancement]
  • 🟥 Minecraft modpack installer
  • 🟥 Multi-world support
  • 🟥 Template auto-updater
  • 🟥 Prometheus observability pipeline

📅 Sprint Plan (Next 3 Days)

DAY 1 – Dev Containers (Dec 8)

Objective: Enable developer environment provisioning

🎮 Minecraft Variant Status Matrix

Variant Install Verify Self-Repair Start Ready Detection Status
Vanilla ✅ ✅ ✅ ✅ ✅ PRODUCTION
Paper ✅ ✅ ✅ ✅ ✅ PRODUCTION
Purpur ✅ ✅ ✅ ✅ ✅ PRODUCTION
Fabric ✅ ✅ ✅ ✅ ✅ PRODUCTION
Forge ✅ ✅ ✅ ✅ ✅ PRODUCTION
NeoForge ✅ ✅ ✅ ✅ ✅ PRODUCTION

Supported Versions: 1.12.2, 1.16.5, 1.18.2, 1.19.2, 1.20.1, 1.21.x

🛠️ Troubleshooting Guide (Per Variant)

Vanilla / Paper / Purpur

Common Issues:

  • Missing server.jar → Download failure, re-provision
  • Non-executable start.sh → Auto-repaired by agent
  • Log delay causing READY timeout → Improved detection logic

Self-Repair: Automatically fixes permissions, validates Java symlink

Fabric

Common Issues:

  • Installer creates fabric-server-launch.jar not server.jar
  • Agent expects fabric-server.jar naming
  • Self-repair renames to server.jar for consistency

Self-Repair: Finds fabric jar and renames to standard name

Forge / NeoForge

Common Issues:

  • Uses run.sh instead of server.jar
  • Java version mismatch (17 vs 21)
  • Long startup time (60-90s for READY)

Self-Repair:

  • Patches run.sh with correct Java path
  • Ensures executable permissions
  • Extended timeout for READY detection

Detection: Parses for "Done" message in logs

🎯 What's Working (90%)

Provisioning Pipeline ✅

API Orchestration:

  • VMID sequential allocation
  • LXC cloning from template 800
  • IP detection (10.200.0.X)
  • Agent configuration delivery

Agent Execution:

  • Async provisioning (goroutine)
  • Multi-variant installation
  • Self-repair + verification
  • RUNNING state reporting

Edge Publishing:

  • Cloudflare A + SRV records
  • Technitium internal DNS
  • Velocity proxy registration

What's Nearly Done (5%)

🟧 Directory Normalization:

  • Standardizing /opt/zlh/<game>/<variant>/world
  • Ensuring consistency across variants

🟧 Verification Edge Cases:

  • Reducing false negatives in READY detection
  • Improving self-repair robustness

What's Next (5%)

🟦 Dev Containers:

  • Spec defined, implementation starting
  • Timeline: 1 day sprint

🟦 EdgeState Schema:

  • Track Cloudflare record IDs
  • Fix DNS deletion reliability
  • Timeline: 1 day sprint

🟦 Reconciliation:

  • Auto-heal partial failures
  • Detect orphaned resources
  • Timeline: 1 day sprint

🚨 Known Bugs (Non-Blocking)

Agent Bugs (System Works, But...)

  1. Forge server.jar Glob Logic (artifacts.go lines 112-116, 147-151)

    • Issue: Tries to find *server.jar but Forge ≥1.17 doesn't create this
    • Fix: Remove glob/rename logic (Forge uses run.sh + libraries/)
    • Impact: Unnecessary code, no functional impact
    • Priority: Low (cleanup)

  2. ensureProvisioned() Fallthrough (agent.go lines 155-171)

    • Issue: After Forge check, falls through to check server.jar
    • Fix: Add else to prevent fallthrough
    • Impact: Minor efficiency issue
    • Priority: Low (optimization)

  3. Forge Stop Command Exclusion (process.go line 83)

    • Issue: Excludes Forge from receiving stop command
    • Fix: Remove exclusion (Forge accepts stop commands)
    • Impact: Requires manual workaround
    • Priority: Medium (UX)

Platform Gaps (Launch Blockers for Public Release)

  1. WebSocket Console Streaming 🔴

    • Current: HTTP polling
    • Needed: Real-time streaming
    • Why: Industry standard, competitive requirement
    • Effort: 4-6 hours

  2. Crash Loop Protection 🔴

    • Current: Immediate restart
    • Needed: Exponential backoff (5s, 10s, 15s), stop after 3 crashes
    • Why: Prevent resource thrashing
    • Effort: 2 hours

  3. Disk Space Monitoring 🔴

    • Current: No checks
    • Needed: Alert <1GB, prevent start if insufficient
    • Why: Prevent world corruption
    • Effort: 1 hour
