Error Handling

Divekit uses a centralized categorized error model built around internal/error (apperror), command middleware, and internal/shell/logging.

This page is now only a summary. The implementation-coupled source of truth lives in the CLI repository under docs/architecture/error-handling.md.

Stable Summary

• commands should return typed errors, not format terminal output themselves
• user messages and technical details should stay separate
• exit codes are determined centrally
• logging should go through the shared logging package
• fallback behavior should be explicit and observable
