-- ============================================================================
-- Production migration: apikey.alias (unique) + markdown/patch authorship
-- ============================================================================
-- Idempotent. Safe to run multiple times. Target: MySQL 8 (no native
-- ADD COLUMN IF NOT EXISTS, so columns are guarded via information_schema
-- + a prepared statement). Mirrors the app's db.run_migrations(); running
-- both is harmless.

-- Apply against the application schema, e.g.:
-- docker exec -i mysql sh -c 'mysql -uroot -p"$MYSQL_ROOT_PASSWORD" hangmanlab' \
-- < 2026-05-16_apikey_alias_authorship.sql
