Expand description

The intent journal written BEFORE uploads: which keys this barrier will touch and under which flush_uuid, so a restarted container can recognize its own crashed/torn PUT at the 412 (AdoptOwn) instead of mistaking it for a foreign write. recent_uuids keeps the last few barriers’ uuids for the same reason. A change ANOTHER writer made that this workspace’s merge carried into the manifest but not yet into the tree: the next consume fetches it (or, for a deletion, removes a clean local copy).

Writer-local on purpose. These rode the SHARED inbox as merge-preserved entries, which was right while one syncer wrote a workspace and wrong the moment two did: the other writer’s consume found its own bytes there, called the entry integrated and dropped it, and the writer that needed it never fetched the change; a sync read it as remote truth after the manifest had moved past it. And a peer’s DELETE had no carrier at all. A pod replacement loses this file with the baseline, which is correct: the replacement’s checkout materializes the whole manifest.

Fields§

§path: String§etag: Option<String>

The etag the manifest cites; None means the path was deleted.

§crc64_b64: Option<String>
