Introduction to the Min Length Check
The Min Length check asserts that no value in a text field is shorter than a configured number of characters. Use it to guard identifiers with a known size and to catch placeholder entries that pass a presence check but carry no information.
This section is the complete guide to the check. The Deep Dive covers the definition, properties, and full evaluation semantics, explains how anomalies are reported, walks through production examples, and collects best practices; the How-tos are step-by-step tutorials for creating, editing, and deleting a check; the API page documents the payload for programmatic use; and the FAQ answers the most frequent questions.
