Shared Error-Handling Patterns

• Subclass Error with typed messages
• Never swallow errors silently
• Prefer Result<T, E> return types in business logic
• Log only at boundaries, never inside pure functions
• Validate inputs only at the system edge
• Treat all third-party API responses as untrusted input
• Bail early on contract violations rather than degrading silently
