Prelude

A Precion pre-decision guard.

Prelude is a pre-decision guard for critical system actions.

It prevents actions from executing when system conditions are not explicitly safe.

Not later. Not after review. Before execution.

The problem

Modern systems deploy, migrate, and automate faster than organizations can reliably judge consequences.

Most incidents are not caused by faulty code. They are caused by correct actions executed at the wrong time.

Once executed, these actions cannot be undone.

What Prelude does

Prelude is placed in front of a critical action.

Before execution, it evaluates the current system state against deterministic conditions.

It returns exactly one result:

Allow
or
Block

The decision is recorded. Execution continues — or stops. No additional behavior is triggered.

What Prelude is not

Prelude does not explain decisions. It does not suggest alternatives. It does not optimize outcomes.

There are no confidence scores, no retries, no tuning parameters.

The state is either acceptable or it is not.

Why this matters

Some actions are too expensive to guess.

• Deploying to production
• Running schema migrations
• Triggering irreversible workflows

Prelude exists for the moment where automation must pause and responsibility must be explicit.

Intended use

Prelude is designed for teams that already automate.

Teams that trust their pipelines but require a final, deterministic decision point before irreversible execution.

If flexibility is the goal, this is not the right system. If certainty is required, it may be.

Access

Prelude is intentionally limited.

There is no self-service onboarding. There is no public signup.

Access is granted deliberately.
