Tasks

  • Add namespace flags; define whitelist; reject ambient variables and network access.

Gherkin Specification Delta

Scenario: Deliverable behavior

  • GIVEN the stated prerequisites and inputs
  • WHEN the feature is exercised
  • THEN default settings, when a workflow inspects env or opens network, then only whitelist exists and network is unavailable.
