Prelude stops actions when they should not happen.
Not later.
Not after review.
Before execution.
Modern systems deploy, migrate, and automate faster than people can judge.
Most failures do not come from broken code.
They come from actions that technically worked at the wrong moment.
Once executed, they cannot be undone.
Prelude sits in front of a critical action.
Before the action runs, it checks the current system state.
It returns one answer.
Allow.
Or block.
That decision is stored.
The system moves on. Or it stops.
Nothing else happens.
Prelude does not explain.
It does not suggest alternatives.
It does not try to be helpful.
There is no tuning.
No confidence score.
No second attempt.
The state either allows the action
or it does not.
Some actions are too expensive to guess.
Deploying to production.
Running migrations.
Triggering irreversible workflows.
Prelude exists for the moment
where speed must pause
and responsibility must become explicit.
Prelude is for teams that already automate.
Teams that trust their systems
but still want a final, explicit decision point
before something permanent happens.
If you want flexibility, this is not it.
If you want certainty, it might be.
Prelude is intentionally limited.
If you want to use it,
you ask first.
