data.lifecycle_value

Lifecycle sets a value that isn't fixed.

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

A transition sets each field to a fixed value, the same every time it runs:

example
entity Todo {    id: Uuid    deleted_at: Instant?    edited_at: Instant?    lifecycle: {        visible: deleted_at == none        transitions: {            delete: {                set: {                    deleted_at: edited_at                }            }        }    }}
jadpo checkcheck failed: 1 error, 1 file

error edited_at is another field of the record

--> main.jadpo:11:33

   |11 |                     deleted_at: edited_at   |                                 ^^^^^^^^^ a field, not a value
reason
A transition sets each field to a fixed value (a literal, an enum value, none or clock.now), the same every time it runs; copying one field into another isn't one.
next
Use a literal, an enum value, none or clock.now (agent)
