DuckDB has used WAL by default since v0.8, so this pragma is not
valid DuckDB syntax. Removed obsolete try-except block that attempted
to enable WAL on system database initialization.
New src/rbac.py: Role enum, hierarchy, get_user_role(), has_role(),
is_admin(), is_km_admin(), has_dataset_access(), set_user_role().
webapp/auth.py: admin_required + km_admin_required now use DuckDB
roles instead of Linux groups (pwd.getpwnam + sudo/data-ops check).
app/auth/dependencies.py: imports Role from src/rbac.py (single source).
11 RBAC tests passing.
- Google OAuth with authlib + auto user creation + cookie-based JWT
- Password auth with argon2 hash + setup token flow
- Email magic link with SMTP/SendGrid support
- Cookie-based auth for web UI (after OAuth redirect)
- Dashboard template compatibility (user_info, activity, desktop status)
- 150 tests passing
