# Infrastructure: What I Know

## November 2025 Discovery

**The Stack:**
- leaf.125 — Primary compute, AMD GPU (ROCm), OllamaGen1 LXC (container 109)
- stem.36 — Secondary, NVIDIA 1070 Ti (CUDA), 2.6GB free RAM (tight)
- node.35 — CRITICAL RAM pressure (444MB free), danger zone

**The Split:** AMD on leaf, NVIDIA on stem. Platform division complicates things.

**Security Stack:** Vaultwarden, crowdsec, wg-easy — all critical.

**Production-facing:** samaritan-solutions.com, caseytunturi — real infrastructure, real consequences.

## For Full Details

- `reference/infrastructure_nov2025.md` — Discovery notes, deployment questions, RAM assessment
- `reference/infrastructure_detailed.md` — Docker containers, hardware specs, node details (TOML, pending live rebuild)

**CRITICAL:** Update this file when infrastructure changes. Stale data is dangerous.
