# Loop

Repeated execution cycle

Layer: Infrastructure · Category: Primitives

## Mechanism

A control flow structure that repeats a sequence of [Work](https://mindscape.world/scapes/bootstrap/Work.md) until a specific [Condition](https://mindscape.world/scapes/bootstrap/Condition.md) is met. Essential for feedback, learning, and persistent processes.

## Invariants

- Termination Guarantee: Must have a proven exit condition (or explicit Daemon mode).
- Progress: State must change between iterations to avoid infinite freeze.

## Failure modes

—

## Builds on

- [Condition](https://mindscape.world/scapes/bootstrap/Condition.md) (Infrastructure; Accepts)
