# Trialhaven

Run a bounded departure from standing rules with safeguards, review points and an exit back

Layer: Society · Category: Governance

## Mechanism

An experiment that departs from standing rules runs inside declared bounds of scope, duration and affected parties, with safeguards, scheduled review points and an exit route whose [Reversibility](https://mindscape.pages.dev/bootstrap/Reversibility.md) has been checked. Crossing a declared bound ends the trial.

## Invariants

- The trial declares its scope, duration and affected parties.
- It has scheduled review points and an exit route that restores the prior state.
- Crossing a declared bound ends the trial.

## Failure modes

- Permanent pilot: the trial is extended indefinitely without becoming policy.
- Unreachable exit: by the time it is needed, the exit no longer restores the prior state.

## Caution

Departs from standing rules by design — scope and audit who may declare a trial, or 'trial' becomes a label for bypassing them.
