OS environment variables for THIS subprocess · a key→value map applied over the composed environment. Nothing is inherited — the ambient environment reaches a task only through `permits.env` (spec/01-envelope.md §permits). One of 62 words the served contract declares, projected from workflow.schema.json, the same file your editor validates against.
