Dynamic Parameter Dependencies — context-aware wizard

[jacobhuemmer]

Summary

Parameters that depend on each other. Selecting one value dynamically populates options for another.

Design

• New source field in parameter YAML:

  parameters:
    - name: namespace
      type: select
      options: [production, staging, dev]
    - name: deployment
      type: select
      source: "kubectl get deploy -n \${namespace} -o name"

• Wizard fetches options when the dependency is filled
• Cached with TTL to avoid repeated calls
• Fallback to manual text input if source command fails

Impact

Makes the wizard context-aware instead of static. Eliminates "what's the deployment name again?" friction.
