Enum BlockedReason 

#[non_exhaustive]
pub enum BlockedReason {
    RenameCollision,
    TargetNotFound,
    InvalidPayload,
}

Why a StructuralOp was TransformOutcome::Blocked.

A Blocked outcome guarantees the input CST is unchanged (FR-003, §I).

#[non_exhaustive] so future block reasons can be added without a breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RenameCollision

A rename would collide with an existing field/key in the same struct/map.

TargetNotFound

The addressed parent / element could not be located in the document (e.g. an out-of-range index, or a node from a different tree).

InvalidPayload

The op is not valid for the addressed node (e.g. an op that needs a struct applied to a list element, or new payload text that does not parse).
