Owner preference: the bulk of TRADING_*/TRIGGER_* logic switches should live in the DB, not the compose file (keys + connection info stay in compose — the DB address cannot live inside the DB, and secrets don't belong in a table the stack can SELECT). Precedence at boot: compose env < overrides.env < config_overrides table; every entrypoint already routes through env_overrides.load(), which now applies the table last. Admin /api/config and profile-apply write the table (secrets whitelist unchanged); the config page shows source=database. DB down = silent fall-through to file/compose, boot never blocks on config. One-shot migration: python -m runtime.env_overrides seed-from-env run in any stack container to copy its current effective knobs into the table, after which the compose lines are dead weight strippable at the next redeploy.
