 ### 2.3 Add `DB_PROVIDER` to config schema in 3 older repos
 
 All 9 repos already use `@bytelyst/datastore` in their `datastore.ts`. However, 3 older repos (LysnrAI, MindLyst, ChronoMind) read `DB_PROVIDER` directly from `process.env` inside `datastore.ts` instead of declaring it in their Zod config schema. This means `DB_PROVIDER` isn't validated at startup.
