INTRODUCTION

English translation pending.

CORE DEFINITION

A baffle is a partition placed in a flow path to deflect, slow, or isolate movement, as in the bulkheads that keep a hull breach from flooding every compartment. The model treats partitions as control elements: their number, position, and opening rules determine how the system handles surges and local failures. The core claim is that isolation trades a measure of throughput for containment, and that the trade is worth making wherever a local failure could propagate system-wide. The qualification is that the partition must be designed for the pressures on both sides, since a baffle that jams open or shut converts a control device into a failure point.

SCAFFOLDING EFFECT

Reduce cognitive load

- Map the regions: identify where a failure in one part would otherwise propagate into the others. - Set the rules: define what condition opens and closes each partition. - Size for the pressure: check that the partition holds the differential it will actually face.

Anchor fast decisions

In a connected system, damage travels along the same paths that carry normal flow, so the connections that make the system efficient also make it fragile. Inserting a partition breaks those paths at chosen points, which converts one large failure into several smaller independent ones. The cost is real: partitions restrict flow in normal operation and add maintenance and failure modes of their own. The design question is where containment is worth more than throughput, since a partition that cannot hold its differential provides the cost without the protection.
