@@ -54,7 +54,7 @@ Two independent mechanisms — don't cross-wire them:
 - PostgreSQL via `Npgsql.EntityFrameworkCore.PostgreSQL` 10. Connection string key is `ConnectionStrings:Default` (see [Mws.Api/appsettings.json](Mws.Api/appsettings.json)); fallback to `localhost:5432` dev creds `mws/mws`. Override via env if you must.
 - Enum columns are stored as `varchar(20)` (not ints) — preserve that for any new enum.
 - Self-referencing `Document.ParentId` uses `Restrict` to block accidental cycles. Cascade delete is implemented in `DeleteDocumentHandler` via a manual descendant walk (`DocumentAccess.DeleteDescendantsAsync`); do not switch the FK to cascade.
-- `DbSeeder` ([Mws.Infrastructure/Persistence/DbSeeder.cs](Mws.Infrastructure/Persistence/DbSeeder.cs)) seeds two system roles (`Admin` — full CRUD on every screen; `Member` — view-only on Projects, CRUD on Tasks/Documents (no delete), and no access to Users/Permissions/Master Data) plus admin/alice/bob (password: `password`, admin → Admin role, alice/bob → Member) and one demo project on first boot. System roles are re-synced to this canonical permission matrix on every startup (`SyncSystemRoleAsync`), so edits made to them through the Roles UI do not persist across restarts. Skips user/project seeding if any users exist. System roles (`Role.IsSystem = true`) can't be deleted via `DeleteRoleCommand`.
