# Studio Products — Tech Stack (living)

<!-- wiki:featured -->

**Component inventory SSOT:** [`docs/tech-stack/inventory.yaml`](../tech-stack/inventory.yaml) → `/wiki/` (Layers · Technology).  
This file is **products narrative only** — do not duplicate inventory tables here. Product rows are Layer 3; ports/units stay in `products/registry.yaml`.

**Track version:** see `VERSION` · **Audited:** 2026-10-12  
**Primary source (ports/units):** `products/registry.yaml` (symlinked here as `registry.yaml`).  
**Secondary:** running systemd / listening ports.
