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///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 --- ## 🎯 Glossary of Moving Parts | Component | Description | Status | |-----------|-------------|--------| | **Agent** | Go service handling provisioning, verification, server lifecycle | ✅ Production | | **ProvisionAll()** | Downloads & extracts variant runtime | ✅ Working | | **verify.go** | Multi-variant validation + auto-repair | ✅ Working | | **detectMinecraftReady()** | Parses log for READY state | ✅ Improved | | **provisionAgentInstance()** | Main API orchestration entrypoint | ✅ Working | | **Velocity Plugin** | ZpackVelocityBridge for proxy routing | ✅ Operational | | **Edge Publisher** | Updates Cloudflare + Technitium + Velocity | ✅ Create working, ⚠️ Delete needs IDs | | **VMID Allocator** | Prevents ID collisions | ✅ Working | | **PortAllocatorService** | Dynamic per-VM port pool management | ✅ Working | | **Agent Template** | Golden LXC (VMID 800) containing agent + deps | ✅ Production | | **Directory Spec** | `/opt/zlh///world` | 🟧 In progress | | **EdgeState** | DNS record ID tracking table | 🟦 TODO | | **Dev Containers** | Developer environment provisioning | 🟦 Next sprint | --- ## 📈 Launch Readiness Matrix ### **Core Platform** (100% ✅) -
