domain-exception-hierarchy

What problem does it solve?

Creates a structured, semantic domain exception hierarchy to ensure precise error diagnosis, consistent propagation, and safe cross-layer boundaries.

Core Features & Use Cases

• Abstract base with contract: a sealed domain exception base carrying code, context, timestamp, and cause.
• Categorized leaves with typed context: specialized exceptions for Validation, State, Infrastructure, and Business errors with strong typing.
• Adapter translation & resilience: one-way translation from infra to domain, plus layered handlers (retry/fallback) and API-friendly payloads.
• Audit and observability: ensures exceptions are actionable and traceable across domain, application, and infrastructure.

Quick Start

Create an abstract base exception with a typed context, then implement category leaves and an adapter translator.
