-- NOT A MIGRATION YET. Deliberately outside the .sql glob so it cannot run.
--
-- This is the data move for task #23. It must not be applied until the Gmail
-- handlers read the mailboxes table instead of user_settings: it empties the
-- settings row, and running it early would disconnect a working mailbox.
--
-- Rename to 0016_gmail_is_a_mailbox.sql when internal/httpapi/gmail_handlers.go
-- has been rewritten.
-- The values move across still sealed. Both tables seal with the same key and
-- store the same string, so copying the ciphertext verbatim is not a shortcut
-- around the encryption — it is the encryption, untouched. That also means this
-- migration does not need the key, which a migration has no business holding.
--
-- `username` is the address the account reports, and it is what makes the unique
-- index meaningful. It may be empty on rows that never got that far; two such rows
-- cannot exist for one person anyway, because the settings table could only hold
-- one.
