-- KNOWN ISSUES
-- ============================================================
-- 1. person_details.key stores passwords in PLAIN TEXT
--    → Need migration 002_add_password_hash.sql
--
-- 2. access_to_deployments is TEXT with comma-separated IDs
--    → Should be junction table, but works for now
--
-- 3. No push_tokens table yet
--    → Need migration 003_create_push_tokens.sql
