! Action

The action operator commits an addressed intention. A selected posture becomes a consequence you can inspect.

This is where a question becomes a change: ? looks, ! commits.

^"action_contract"{

Contract

In hand

Commit a local action or a projection. When the commit is unavailable, the missing precondition stays stated, and the page can show what a completed commit changed.

What it means

The mark is attention taking a position, force that stays accountable to the current frame. The intention stays readable in the moment before the consequence lands.

Brace Physics

The brace discharges. The release is visible as navigation, a projection, or a changed register.

Before and after

Prefix !x primes the next unit as a committing move. Postfix x! marks that the unit has been acted through. Use @x only when you mean perspective — situating the viewpoint, not forcing consequence.

?["action_example"]

Example

!project(surface)
!inspect(operator)
!apply(filter)

Take this example apart in the parser: each mark becomes a token you can inspect, and the parser says whether the source rebuilds exactly.
