📋 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:

  1. CRITICAL: Push API to git
  2. Add vanilla 1.21.8–1.21.11 to artifact tree
  3. Verify NeoForge installer naming fix

🔒 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
