## Purpose
Standardize application error handling into a coherent architecture: custom error hierarchies, typed domain errors, HTTP/RPC status mappings, sanitized client responses, and structured observability logs.
## When to Use
- When error handling is fragmented with ad-hoc `try/catch` blocks, string checks, or unhandled promise rejections.
- Designing error responses for public REST/gRPC APIs.
- Setting up retry policies, circuit breakers, and graceful fallback behaviors.
## What to Analyze
1. **Error Hierarchy**: Base domain error, validation errors, not found errors, authorization errors, external service errors.
2. **Transport Mapping**: Clean translation from internal domain error classes to HTTP status codes / RFC 7807 Problem Details.
