Enum ShardStatus 

pub enum ShardStatus {
    Active,
    Sealed,
}

Lifecycle status of a WAL shard, persisted in ShardManifest.

Sealed is the durable in-doubt record for drop-table two-phase commit: a sealed shard refuses new writer claims (enforced in claim_epoch) but is reversible back to Active on rollback.

Variants

Active

Normal: the shard accepts writer claims.

Sealed

A drop is in flight: claims are refused. Reversible.
