# 📋 ZeroLagHub - Quick Status Reference (March 1, 2026)

**Use This For**: Quick check of what's been done recently and what needs attention

---

## ✅ What Was Completed (February 7-8, 2026)

### **1. Customer ID Standardization**
- **Decision**: Use Prisma CUID (`User.id`) everywhere
- **Impact**: No more mixed ID formats
- **Action Needed**: Frontend stop hardcoding `u-dev-001`
- **Docs**: `zlh-grind/SCRATCH/2026-02-07_customer-id-schema.md`

### **2. Prometheus + Grafana Live**
- **Status**: ✅ COMPLETE
- **Working**: HTTP service discovery, all containers being scraped
- **Next**: API metrics endpoint for portal
- **Docs**: `zlh-grind/SCRATCH/2026-02-07_prometheus-grafana.md`

### **3. Host Controls Added**
- **Backend**: ✅ Done (Start/Stop/Restart Host)
- **Frontend**: 📋 Needs wiring
- **Safety**: Delete failsafe kept
- **Docs**: `zlh-grind/SCRATCH/2026-02-07_host-controls-and-delete-failsafe.md`

## ✅ What Was Completed (February 21, 2026)

### **4. Game.js Implementation**
- **Status**: ✅ COMPLETE
- **What**: Dedicated game telemetry router
- **Endpoint**: `GET /api/game/servers/:vmid/players`
- **Integration**: Agent poller + Redis caching

### **5. Player Button UI Fix**
- **Status**: ✅ RESOLVED
- **Issue**: Button not rendering (flex-wrap collapse)
- **Solution**: Layout restructure + shrink-0

### **6. Engine Abstraction Strategy**
- **Decision**: Design now, implement when adding game #2
- **Action**: Add `engineType` DB field (default 'minecraft')
- **Defer**: Engine classes until Rust/Terraria development
- **Rationale**: Avoid premature abstraction

### **7. Agent Phase 1 Feature Set**
- **Status**: ✅ COMPLETE (shipped Feb 21-22)
- **Mod management**: GET/POST/PATCH/DELETE `/game/mods/*`
- **Process metrics**: `GET /metrics/process`
- **Readiness probe**: Minecraft start/restart race mitigation
- **Update system**: `ZLH_AGENT_UPDATE_MODE=notify|auto|off`
- **Docs**: `Agent_Endpoint_Specifications_Phase1.md`

## ✅ What Was Completed (February 22, 2026)

### **8. NeoForge Artifact Support**
- **Status**: ✅ COMPLETE (artifact tree expanded)
- **Versions**: 1.21.1, 1.21.4, 1.21.11
- **Contract**: `neoforge-installer.jar` normalized filename
- **Rationale**: 1.21.1 has 16,000+ mods; dominant NeoForge ecosystem

### **9. Artifact Resolver Strategy Decided**
- **Status**: ✅ DECIDED
- **Phase 1**: `zlh-artifactd` as Modrinth/NeoForge proxy — no local mod storage, no catalog maintenance
- **Phase 2**: Caching layer based on real usage patterns
- **Phase 3**: Full orchestrator (game jars + runtimes + mods unified)
- **Rationale**: Single-operator sustainability; ship value at each stage

### **10. Mod Platform Decision**
- **Status**: ✅ DECIDED
- **Primary source**: Modrinth API (`api.modrinth.com/v2`) — open, no key, hash provided, NeoForge filter support
- **CurseForge**: Manual SFTP upload by user (hostile download flow, defer)
- **Curated catalog**: Abandoned — Modrinth IS the catalog

---

## ✅ What Was Completed (February 23, 2026)

### **11. Mod System Now Operational**
- **Status**: ✅ COMPLETE — full lifecycle confirmed end-to-end
- **API**: Modrinth search, install/list/enable/disable/delete behind auth + ownership
- **Frontend**: Mod search drawer, installed panel, enable/disable/delete, toast notifications
- **Engine metadata bug fixed**: `engineType`/`engineVersion` contract corrected
- **Docs**: `Session_Summaries/2026-02-23_Mod-System-Operational.md`

---

## ✅ What Was Completed (March 1, 2026)

### **12. Upload Pipeline + Filesystem Consolidation**
- **Status**: ✅ IMPLEMENTED — transport tuning in progress
- **Upload model**: Direct to runtime root, atomic, no staging, no symlinks
- **Provenance**: `.zlh_metadata.json` tracking, `stat` returns `source`
- **Transport**: Switched from `fetch()` to raw `http.request` piping
- **Docs**: `Session_Summaries/2026-03-01_Upload-Pipeline-Filesystem-Consolidation.md`

---

## 🚨 Critical Outstanding Issues

1. **zlh-api NOT IN GIT** - Still empty since Dec 28 — CRITICAL RISK
2. **DNS Fix Unverified** - Can't check without API in git
3. **Frontend Customer ID** - Still hardcoding `u-dev-001`
4. **Host Controls UI** - Backend ready, frontend not wired
5. **Vanilla MC versions** - Need to add 1.21.8–1.21.11 (source: Mojang version manifest)
6. **Upload transport tuning** - Timeout categories + error logging incomplete

---

## 🚀 Active Development (Current)

### **API Work (GPT)**:
- Fix customer ID hardcoding (use `req.user.id`)
- Improve upload transport diagnostics
- Increase upload route timeout

### **Frontend (GPT)**:
- Wire host controls UI
- Fix customer ID hardcoding

### **Artifacts (User)**:
- Add vanilla 1.21.8–1.21.11 from Mojang manifest
- Confirm NeoForge installer naming contract resolved

### **User (Critical)**:
- **Push API to git** — this is the #1 blocker

## 🔖 Next Session Start Here

### **For GPT (API + Frontend)**:
1. Fix customer ID hardcoding (`req.user.id`)
2. Wire host controls UI
3. Upload transport diagnostics + timeout increase

### **For User**:

## 🔒 Security Reminders

**Before User Uploads** (Phase 2):
- [ ] ClamAV + VirusTotal integration
- [ ] Quarantine workflow
- [ ] Manual review queue
- [ ] Incident logging

**Current Phase 1** (Modrinth-sourced + user uploads to allowlist only):
- ✅ Hash verification mandatory (SHA-512 from Modrinth)
- ✅ Container isolation active
- ✅ Non-root game server user
- ✅ Network segmentation enforced
- ✅ Download from trusted sources only (Modrinth, NeoForge maven)
- ✅ Upload allowlist enforced by agent

---

## 📊 Platform Progress

**Feb 7**: 93%
**Feb 21**: 94%
**Feb 22**: ~95% (agent feature set complete, artifact strategy locked)
**Feb 23**: ~96% (mod system fully operational end-to-end)
**Mar 1**: ~97% (upload pipeline implemented, filesystem model stable)

**Remaining for Launch**:
- ⚠️ API into git (blocker)
- ⚠️ Upload transport tuning
- ⚠️ Host controls UI wiring
- ⚠️ Vanilla 1.21.8–1.21.11 artifact additions
- ⚠️ Customer ID hardcoding fix
- ⚠️ Security audit

## 🔑 Key Architectural Decisions (Feb 21 – Mar 1)

**DEC-009**: Game-specific API organization (separate game.js)
**DEC-010**: Engine abstraction timing (design now, implement later)
**DEC-011**: Mod security model (Modrinth Phase 1, uploads Phase 2)
**DEC-012**: Developer mod pipeline (dev container → game server)
**DEC-013**: Artifact resolver Phase 1 = Modrinth proxy, no local mod storage
**DEC-014**: Modrinth as primary mod source; CurseForge = SFTP fallback
**DEC-015**: NeoForge version coverage = 1.21.1, 1.21.4, 1.21.11 only
**DEC-016**: Direct runtime upload model (no staging, no symlinks)
**DEC-017**: `.zlh_metadata.json` as provenance layer (source field on stat)
**DEC-018**: Raw http.request piping for upload proxy (no fetch streaming)

**Last Updated**: March 1, 2026
**Platform Status**: ~97%
**Critical Blocker**: API not in git
**Next Major Milestone**: API into git + upload transport tuning complete
