2025-10-12 (Day 1) - Foundation Complete

Time Started: ~19:49 UTC Time Completed: ~21:30 UTC Goals: Build server backend + Linux agent foundation

Progress Summary

✅ Server Backend (Go + Gin + PostgreSQL)

• Complete REST API with all core endpoints
• JWT authentication middleware
• Database migrations system
• Agent, update, command, and log management
• Health check endpoints
• Auto-migration on startup

✅ Database Layer

• PostgreSQL schema with 8 tables
• Proper indexes for performance
• JSONB support for metadata
• Composite unique constraints on updates
• Migration files (up/down)

✅ Linux Agent (Go)

• Registration system with JWT tokens
• 5-minute check-in loop with jitter
• APT package scanner (parses apt list --upgradable)
• Docker scanner (STUB - see notes below)
• System detection (OS, arch, hostname)
• Config file management

✅ Development Environment

• Docker Compose for PostgreSQL
• Makefile with common tasks
• .env.example with secure defaults
• Clean monorepo structure

✅ Documentation

• Comprehensive README.md
• SECURITY.md with critical warnings
• Fun terminal-themed website (docs/index.html)
• Step-by-step getting started guide (docs/getting-started.html)

Critical Security Notes

• ⚠️ Default JWT secret MUST be changed in production
• ⚠️ Docker scanner is a STUB - doesn't actually query registries ✅ FIXED in Session 2
• ⚠️ No token revocation system yet
• ⚠️ No rate limiting on API endpoints yet
• See SECURITY.md for full list of known issues

What Works (Tested)

• Agent registration ✅
• Agent check-in loop ✅
• APT scanning ✅
• Update discovery and reporting ✅
• Update approval via API ✅
• Database queries and indexes ✅

What's Stubbed/Incomplete

• Docker scanner just checks if tag is "latest" (doesn't query registries) ✅ FIXED in Session 2
• No actual update installation (just discovery and approval)
• No CVE enrichment from Ubuntu Security Advisories
• No web dashboard yet
• No Windows agent

Code Stats

• ~2,500 lines of Go code
• 8 database tables
• 15+ API endpoints
• 2 working scanners (1 real, 1 stub)

Blockers

None

Next Session Priorities

1. Test the system end-to-end
2. Fix Docker scanner to actually query registries
3. Start React web dashboard
4. Implement update installation
5. Add CVE enrichment for APT packages

Notes

• User emphasized: this is ALPHA/research software, not production-ready
• Target audience: self-hosters, homelab enthusiasts, "old codgers"
• Website has fun terminal aesthetic with communist theming (tongue-in-cheek)
• All code is documented, security concerns are front-and-center
• Community project, no corporate backing
