+
+## Who kenpat is
+- Building the KiteStacks homelab (kitestacks.com) — live production multi-host platform
+- Currently studying CompTIA A+ Core 2, exam goal before July 4th week (hard deadline July 12 2026)
+- Passed A+ Core 1 with highest score in class of 22
+- Cert path: A+ Core 2 → CCNA → AWS SAA → AWS SysOps → CKA → AI

+- Class schedule: Mon/Wed in-person 9am–3/4pm, Tue/Thu/Fri remote
+- Uses Uber to earn money short-term (parking fees and bills)
+
+## This Device
+- **samurai** — Windows 11 gaming desktop, AMD Ryzen 7 7800X3D, 31GB RAM
+- Tailscale IP: 100.74.0.109
+- Connected to monk (primary homelab host) over Tailscale
+
+## Key Devices
+| Device | OS | Tailscale IP | Role |
+|--------|-----|-------------|------|
+| monk | Linux (Debian) | 100.85.209.116 | Primary homelab host, T14s travel laptop |
+| samurai | Windows 11 | 100.74.0.109 | Gaming desktop, study machine |
+| kscloud1 | Linux (Hetzner VPS) | 100.123.254.52 | Cloud replica, shared Authentik DB |
+
+## Private Repos on Forgejo (ssh://git@100.85.209.116:2222/kenpat/)
+| Repo | Purpose |
+|------|---------|
+| kitestacks-homelab | Main homelab RUNBOOK, docs, architecture |
+| homelab-mastery | Complete learning guide — concepts, certs, interview prep |
+| study-tracker | A+ Core 2 study log, practice test scores, cert roadmap |
+| obsidian-vault | Personal notes, commands, study log (synced across devices) |
+| device-setup | Setup scripts for all devices (this repo) |
+
+## Pull full context
+```bash
+# Clone all repos for full picture
+git clone ssh://git@100.85.209.116:2222/kenpat/homelab-mastery.git ~/homelab-mastery
+git clone ssh://git@100.85.209.116:2222/kenpat/study-tracker.git ~/study-tracker
+git clone ssh://git@100.85.209.116:2222/kenpat/obsidian-vault.git ~/obsidian-vault
+```
+
+## Homelab Quick Facts
+- 9 public subdomains at kitestacks.com behind Cloudflare Tunnel
+- Active-active failover: monk + kscloud1 both serve all 9 services
+- SSO via Authentik (shared Postgres+Redis on kscloud1 over Tailscale)
+- Portal (www.kitestacks.com) is custom nginx static site with Python metrics API
+- Forgejo runs on monk at gitforge.kitestacks.com (SSH port 2222)
+
+## Current In-Progress Tasks
+- samurai Obsidian setup: vault cloned, plugins (Git + Pomodoro Timer) still need to be installed manually
+- Portainer SSO: Authentik side done, pending Cloudflare tunnel hostname + Portainer OAuth UI config
+- Oracle Cloud migration: kscloud1 (Hetzner) to be replaced by Oracle VPS (no firm date)
+- Phase 2: Obsidian mind map → HTML mind map sync for homelab portal
+
+## Study Log (A+ Core 2)
+- Started: 2026-06-11 9:15 PM
+- Diagnostic: 50% on Sybex (cold, no prior study)
+- Next test: CompTIA CertMaster (week of 2026-06-16)
+- Full log: ~/study-tracker/certifications/a-plus-core2.md

+## Security Rules
+- Never commit IPs, ports, or passwords to any Forgejo repo
+- Use placeholders: <IP_REDACTED>, <port>, <REDACTED>
+- .env files never committed
