Class SchemaChangeLogEnvelope

Namespace

Kuestenlogik.Bowire.Models

Assembly

Kuestenlogik.Bowire.dll

On-disk / on-wire shape of a workspace's schema-change log (#185): the retained change entries plus the read watermark. "Unread" is derived — an entry is unread when it is newer than LastReadAt — so marking the log read is a single timestamp write instead of a per-entry flag sweep.
