Struct WriterBlock 

pub struct WriterBlock {
    pub writer_id: String,
    pub acquired_at_ms: u64,
}

Who most recently acquired the writer epoch, and when.

Observability only, written during the epoch-acquisition CAS. Fencing authority is writer_epoch + CAS; nothing may consult this block for commit validity, takeover permission, or expiry, and no wall-clock comparison may gate a publish.

There is no session identity here: two runs of the same writer are told apart by acquired_at_ms, not by an id.

Fields

writer_id: String

Stable writer label supplied by the embedding process for diagnostics.

acquired_at_ms: u64

Unix-millisecond stamp of the successful epoch-acquisition CAS.
