`data.lifecycle_section`

Lifecycle has a section it doesn't take, or lacks one it needs.

Area 5, Entities, stores and migrations; not declinable; the next step is usually the agent's.

A lifecycle holds visible:, initial:, transitions: and purge:, each once; a transition holds when: and set:, and purge: holds after: and since::

example

entity Todo {    id: Uuid    deleted_at: Instant?    lifecycle: {        visible: deleted_at == none        hidden: deleted_at != none    }}

jadpo checkcheck failed: 1 error, 1 file

  |7 |         hidden: deleted_at != none  |         ^^^^^^ not a section here

reason: A lifecycle holds visible:, initial:, transitions: and purge:.
next: Remove hidden from the lifecycle (agent)
