mail-backends

How Mail actions pick between the real Gmail API and synthetic local-emails fallback data per user. Use when mail data looks fake or empty, when a user has no connected Google account, or before claiming a message really was sent or fetched from Gmail.

# Mail Backends

## Rule

**Two mail backends, chosen automatically per user.** When the user has a
connected Google account (`isConnected(ownerEmail)`), actions call the real
Gmail API. When no account is connected, the same actions fall back
transparently to synthetic `local-emails` data stored via `getUserSetting` /
`putUserSetting`. Never assume Gmail is connected — actions like
`search-emails`, `list-emails`, `get-thread`, `get-email`, and `move-email`
branch on this internally, so call them the same way either way.
