01 — Per-user isolation
Two locks on every query.
Every row in MAXFORCE belongs to exactly one user. Every database query checks ownership at two layers — your application session and a database-level Row Level Security policy that enforces the same rule independently.
If application code ever forgets to filter by user, the database refuses to return the row. Two locks, not one. Both are enabled on every maxforce_* table. RLS is on by default; service-role access paths still apply the application-layer filter explicitly.
