Struct NamespaceHeadSummary 

pub struct NamespaceHeadSummary {
    pub namespace_id: NamespaceId,
    pub head_seq: ChangeSeq,
    pub current_manifest_id: Option<ManifestId>,
    pub wal_tail_segments: u64,
    pub retention_floor_seq: ChangeSeq,
}

Lightweight namespace head status.

Fields

namespace_id: NamespaceId

head_seq: ChangeSeq

current_manifest_id: Option<ManifestId>

Manifest this namespace has materialized for itself, or None when it has published none yet: a fresh namespace reads from the genesis state, and a fresh fork target reads from its source’s manifest.

wal_tail_segments: u64

Number of visible WAL segments after the current manifest.

Counted from the head’s chain pointers (recent_segments, published under the same CAS as the tip); segment bodies are fetched and validated only for a tail extending past the hinted window. An inspection count for maintenance gating and operators — replay consumers load the validated chain instead.

retention_floor_seq: ChangeSeq
