`change`

The only thing that writes a caller's data. It is written with set, one write or a list, or with run, whose whole is one all-or-nothing write.

Example

TypeScript

export const addNote = change('addNote', {
  access: 'signedIn',
  set: notes.add({ body: input('body') }),
})

Option	Means
`option.change.access`	Who may call the change.
`option.change.set`	The writes of the change, as plain data.
`option.change.run`	The function that makes the change.
`option.change.about`	One sentence on what the change is for.
`option.change.input`	The fields that a call gives.
`option.change.output`	The type of the answer.
`option.change.danger`	Whether AIs and MCP callers ask a person before the change runs.
`option.change.offer`	The outside doors the change is offered to.
`option.change.deprecated`	Marks the change as going away, in the API description and in its answers.
`option.change.system`	Gives the change full access, with the reason.
`option.change.touches`	The tables that a raw SQL write of the change writes.
`option.change.countBy`	For whom the calls of the change are counted.
`option.change.everywhere`	Answers the change only once every machine of the app holds it.
`option.change.plain`	Holds the change to the plain form.
`option.change.was`	The old name of the change, where it was renamed.

A function, markPaid(input), which answers at once. A call is handed to the engine.

code.T0010: it was called with no engine: nothing stands in the runtime slot.
