finalizeSnapshotMetadata marked the snapshot complete and then exported its metadata. A crash after completion but before/during the export left the local index showing the snapshot complete while the destination had no manifest or database, and PruneDatabase (which drops only NULL completed_at rows) kept it: a silently unrestorable snapshot. Reorder so completion is recorded last. CompleteSnapshot is split into PopulateSnapshotBlobs (before the export) and MarkSnapshotComplete (after it). An interrupted export now leaves the snapshot incomplete, so the next run PruneDatabase drops it and re-backs-up the data; the reverse tiny window leaves a restorable snapshot the index reports honestly as remote-only. Update REPOSTRUCTURE.md guarantee 4 and the ARCHITECTURE.md flow. Add a fault-injection test driving the full create path. Model: opus-4-8
