-- Per-user pseudonym store: maps the user's chosen community display name
-- to their Directus user ID. This table lives in per-user kiwi.db only.
-- It is NEVER replicated to the community PostgreSQL — pseudonym isolation is by design.
--
-- A user may have one active pseudonym. Old pseudonyms are retained for reference
-- (posts published under them keep their pseudonym attribution) but only one is
-- flagged as current (is_current = 1).
