3.4 Installation and Environment Validation

Prepare a BioLine account, fkit, and a compatible local container runtime. Use account credentials only for fkit login; do not store them in a repository or task materials.

1. Confirm fkit is available and inspect its help:

   fkit --help
   fkit flow list --json

2. Request command-scoped documentation. Reading Markdown from the official BioLine AI documentation service does not require login:

   fkit flow inspect --docs --docs-json --docs-lang en

3. For an upstream task, sign in and confirm that fkit can discover the relevant Flow and read the BioLine input location.
4. For downstream execution, confirm the local container runtime can disable networking, mount stage read-only, and provide a writable analysis directory.

There is no requirement to build or install the historical downstream image set or maintain a local analysis-component catalogue. At execution time, select an exact version of an existing BioLine Tool, inspect its summary/config, and pull that version on demand. GPU and resource requirements depend on the selected Tool version and the host environment.
