Result and Error

Baseline: main 23.0+ · Verified: main 26.800.0

Contract

• Expected failures (validation, business rule, not found, no rights) → Result with Errors.
• Broken state or contract (module missing, DB down, misconfiguration, bug) → exception.
• One method, one contract: always a Result, or a value plus exceptions for the exceptional case. Never bool/null/-1/['error' => …].
