A condition that prevents a retention plan from being applied safely.

Variants

EngineAnchorUnavailable

Authoritative engine-core retention anchors are not implemented yet.

BranchRequiresBootstrap

A branch depends on history below the proposed effective floor.

Fields

branch: BranchName

User-facing branch name.

fork_position: u64

Position at which the branch inherits its parent.

ProjectionRequiresBootstrap

A registered live view has no authoritative checkpoint at the floor.

Fields

name: String

Registered projection or live-view name.

ConsumerRequiresBootstrap

A durable consumer checkpoint would be stranded below the floor.

Fields

consumer_id: String

Stable consumer identifier.

position: u64

Last acknowledged exclusive continuation.

MaintenanceHandlesOpen

Maintenance cannot apply while bounded readers or feeds are open.

Fields

readers: usize

Number of currently open replay readers.

feeds: usize

Number of currently open committed-batch feeds.
