Under the hood
Useful2 Signal3
Mailboxes, plugin registry, daemon config and plugin cache can now read and write through newer storage.
What's wrong with this entry?
Anonymous. No account, no email.
What
Teammate mailboxes, the plugin marketplace registry, flagged plugins, the daemon config file and the plugin cache each gained a path that reads and writes through a newer storage layer when one is handed in. Without it the existing direct filesystem path runs unchanged. Errors now separate backend faults from parse and corruption faults.
Evidence
failed to load marketplace configuration (v5 backend error)
