Semantic classification attached to an error. The Operation executor uses it for failure versus cancellation diagnostics; presentation policy belongs to the ingress layer that receives the rejection.

Type Declaration

ReadonlyActivation: "activation"

Failure while activating.
ReadonlyCancelled: "cancelled"

Cooperative cancellation. Diagnosed at debug level; the rejection still reaches callers.
ReadonlyExpected: "expected"

Anticipated failure with a safe message.
ReadonlyShutdown: "shutdown"

Failure while shutting down.
ReadonlyTimeout: "timeout"

Ran out of time.
ReadonlyUnexpected: "unexpected"

A bug. Log the full cause; any user-facing presentation should hide internals.
ReadonlyUser: "user"

Caused by user input or state; safe to show verbatim.
ReadonlyValidation: "validation"

Input failed validation at a trust boundary.
