+  Requires macOS/Linux, Python 3.10+, uv, and Ollama with nomic-embed-text
+  (~280 MB). Install the persistent CLI with `uv tool install fidelis-memory==0.1.0`,
+  then run `fidelis init` to install and start the local service. Ingest data
+  with `fidelis watch <path>`, then start a new Loki session so its MCP tools load.
