Solution: Single-script squad with OpenSpec enforcement, drift detection (<2s on schema misses), PR-Agent reviews, and human-in-the-loop gates. Zero-cloud, runs on local hardware.
Impact: 3-day tasks → 3 hours; senior-level quality without external dependencies. Deployable in any folder: Build Info.
Solution: Home-server rebuild calling local APIs for end-to-end video production (n8n → ComfyUI → Remotion → Chatterbox-TTS → Postiz). 85% on-prem, GPU-optimized.
Impact: $500+/month saved; full sovereignty for sensitive workflows. In production: Local Build.
