Enum CleanupTask 

#[non_exhaustive]
pub enum CleanupTask {
    Journal,
    Segments,
    StaleArchives,

    StaleTemporaries,

    RecoveryBackups,
    RepairArchives,
}

One independently selectable cleanup category.

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.

Journal

Remove parser-ignored, missing-segment, and unreadable historical journal lines while retaining every readable revision byte-for-byte.

Segments

Run Oak’s standalone FULL/two-retained-generation segment sweep.

StaleArchives

Remove superseded archive letters and empty incomplete archives.

ExpiredCheckpoints

Remove checkpoints whose valid timestamp is strictly before now.

StaleTemporaries

Remove provably redundant interrupted-operation staging files.

UnreferencedCheckpoints

Remove checkpoints not referenced by string values under /:async.

RecoveryBackups

Apply the explicitly configured age/count policy to recovery backups.

RepairArchives

Rebuild the index of an active archive that has none, retaining the original bytes under a .bak name.

An archive whose trailers were never written is what a killed Oak writer leaves behind, and every other cleanup category is blocked by it: generation decisions may not rest on a recovery scan. Opting into this makes cleanup repair that state instead of refusing it. It is deliberately not a default, because it rewrites an archive, and because a store damaged in the middle rather than at the tail is a case the operator should look at before authorizing.
