Struct MetadataRootState 

pub struct MetadataRootState {
    pub namespace_id: NamespaceId,
    pub manifest_id: ManifestId,
    pub manifest_object_id: ManifestObjectId,
    pub manifest_head_seq: ChangeSeq,
    pub manifest_payload_checksum: String,
    pub updated_at_ms: u64,
}

Cold pointer to the best known materialized metadata root.

Manifest publication compare-and-swaps this object, never the WAL head, so head watchers see only commits. Updates are monotonic in manifest_head_seq; a same-seq replacement may reference a different manifest (pure compaction), and a lower-seq replacement no-ops. This object never defines live visibility.

Fields

namespace_id: NamespaceId

Namespace whose materialized file set this root selects.

manifest_id: ManifestId

Monotonic logical position of the selected manifest.

manifest_object_id: ManifestObjectId

Immutable candidate chosen at manifest_id.

manifest_head_seq: ChangeSeq

Greatest namespace sequence represented by the selected manifest.

manifest_payload_checksum: String

Must equal payload_checksum in the referenced manifest envelope.

updated_at_ms: u64

Unix-millisecond wall-clock stamp for observability and GC grace policy, not ordering.
