Model

This file defines the structural abstraction of the system. It includes the main entities, their attributes, relationships, and key operations. The model serves as a blueprint for implementation and guides the design of the database schema, API endpoints, and business logic.

Cognitive Model & Design Principles

This codebase follows a rule-driven, semantic-first design model. The goal is to reduce ambiguity, minimize cognitive load, and keep the system easy to reason about as it grows.

Do not introduce new structure without a clear, deliberate reason.

When writing or changing code, follow these principles strictly.
