-- 0001_init: M0 migration-framework placeholder.
--
-- Creates a small, harmless key/value table so the migration plumbing
-- (embed -> load -> apply in a transaction -> record in schema_migrations)
-- can be exercised end to end. Real tables (messages, memories, sessions,
-- personas, ...) are added as their own timestamped migrations in later
-- milestones; this placeholder is NOT a domain table.
--
-- Note: key is the primary key on purpose — this is a key/value metadata
-- table, so it intentionally deviates from the "id primary key" convention
-- that applies to domain tables.
