-### 5.1a NoActor Pattern - Test Environment Only
+### 5.1a Authorization in Tests
 
-**IMPORTANT:** The `Mv.Authorization.Checks.NoActor` check is **ONLY for test environment**. It must NEVER be used in production.
+**IMPORTANT:** All tests must explicitly provide an actor for Ash operations. The NoActor bypass has been removed to prevent masking authorization bugs.
 
-**What NoActor Does:**
+**Exception: AshAuthentication Bypass Tests**
 
-- Allows CRUD operations without an actor in **test environment only**
-- Denies all operations without an actor in **production/dev** (fail-closed)
-- Uses compile-time config check to prevent accidental production use (release-safe)
-
-**Security Guards:**
+Tests that verify the AshAuthentication bypass mechanism are a **conscious exception**. These tests must verify that registration/login works **without an actor** via the `AshAuthenticationInteraction` check. To enable this bypass in tests, set the context explicitly:
 
 ```elixir
-# config/test.exs
-config :mv, :allow_no_actor_bypass, true
+# ✅ GOOD - Testing AshAuthentication bypass (conscious exception)
+changeset =
+  Accounts.User
+  |> Ash.Changeset.for_create(:register_with_password, %{...})
+  |> Ash.Changeset.set_context(%{private: %{ash_authentication?: true}})
 
-# lib/mv/authorization/checks/no_actor.ex
-# Compile-time check from config (release-safe, no Mix.env)
-@allow_no_actor_bypass Application.compile_env(:mv, :allow_no_actor_bypass, false)
+{:ok, user} = Ash.create(changeset)  # No actor - tests bypass mechanism
 
-# Uses compile-time flag only (no runtime Mix.env needed)
-def match?(nil, _context, _opts) do
-  @allow_no_actor_bypass  # true in test, false in prod/dev
+# ❌ BAD - Using system_actor masks the bypass test
+system_actor = Mv.Helpers.SystemActor.get_system_actor()
+Ash.create(changeset, actor: system_actor)  # Tests admin permissions, not bypass!
+```
+
+**Test Fixtures:**
+
+All test fixtures use `system_actor` for authorization:
+
+```elixir
+# test/support/fixtures.ex
+def member_fixture(attrs \\ %{}) do
+  system_actor = Mv.Helpers.SystemActor.get_system_actor()
+  
+  attrs
+  |> Enum.into(%{...})
+  |> Mv.Membership.create_member(actor: system_actor)
 end
 ```
 
-**Why This Pattern Exists:**
+**Why Explicit Actors in Tests:**
 
-- Test fixtures often need to create resources without an actor
-- Production operations MUST always have an actor for security
-- Config-based guard (not Mix.env) ensures release-safety
-- Defaults to `false` (fail-closed) if config not set
+- Prevents masking authorization bugs
+- Makes authorization requirements explicit
+- Tests fail if authorization is broken (fail-fast)
+- Consistent with production code patterns
 
-**NEVER Use NoActor in Production:**
+**Using system_actor in Tests:**
 
 ```elixir
-# ❌ BAD - Don't do this in production code
-Ash.create!(Member, attrs)  # No actor - will fail in prod
-
-# ✅ GOOD - Use admin actor for system operations
-admin_user = get_admin_user()
-Ash.create!(Member, attrs, actor: admin_user)
-```
-
-**Alternative: System Actor Pattern**
-
-For production system operations, use the System Actor Pattern (see Section 3.3) instead of NoActor:
-
-```elixir
-# System operations in production
-system_actor = get_system_actor()
+# ✅ GOOD - Explicit actor in tests
+system_actor = Mv.Helpers.SystemActor.get_system_actor()
 Ash.create!(Member, attrs, actor: system_actor)
+
+# ❌ BAD - Missing actor (will fail)
+Ash.create!(Member, attrs)  # Forbidden error!
 ```
 
-**Testing:**
+**For Bootstrap Operations:**
 
-- NoActor tests verify the compile-time config guard
-- Production safety is guaranteed by config (only set in test.exs, defaults to false)
-- See `test/mv/authorization/checks/no_actor_test.exs`
+Use `authorize?: false` only for bootstrap scenarios (seeds, SystemActor initialization):
+
+```elixir
+# ✅ GOOD - Bootstrap only
+Accounts.create_user!(%{email: admin_email}, authorize?: false)
+
+# ❌ BAD - Never use in tests for normal operations
+Ash.create!(Member, attrs, authorize?: false)  # Never do this!
+```

+**Note:** The NoActor bypass has been removed to prevent masking authorization bugs in tests. All tests now explicitly use `system_actor` for authorization.
 
-**Purpose:** Allows CRUD operations without actor in test environment only.

-
-**Security:**

-# With NoActor (test environment only)
-member = create_member(%{name: "Test"})
-
-# Production behavior (NoActor returns false)
-member = create_member(%{name: "Test"}, actor: user)

+  Returns the default role ID for new users.
+
+  This function is called automatically when creating a user without an explicit role_id.
+  It fetches the "Mitglied" role from the database without authorization checks
+  (safe during user creation bootstrap phase).
+
+  The result is cached in the process dictionary to avoid repeated database queries
+  during high-volume user creation. The cache is invalidated on application restart.
+
+  ## Bootstrap Safety
+
+  Only non-nil values are cached. If the role doesn't exist yet (e.g., before seeds run),
+  `nil` is not cached, allowing subsequent calls to retry after the role is created.
+  This prevents bootstrap issues where a process would be permanently stuck with `nil`
+  if the first call happens before the role exists.
+
+  ## Performance Note
+
+  This function makes one database query per process (cached in process dictionary).
+  For very high-volume scenarios, consider using a fixed UUID from Application config
+  instead of querying the database.
+
+  ## Returns
+
+  - UUID of the "Mitglied" role if it exists
+  - `nil` if the role doesn't exist (will cause validation error due to `allow_nil? false`)

-  Custom Ash Policy Check that allows actions when no actor is present.
-
-  **IMPORTANT:** This check ONLY works in test environment for security reasons.
-  In production/dev, ALL operations without an actor are denied.
-
-  ## Security Note
-
-  This check uses compile-time environment detection to prevent accidental
-  security issues in production. In production, ALL operations (including :create
-  and :read) will be denied if no actor is present.
-
-  For seeds and system operations in production, use an admin actor instead:
-
-      admin_user = get_admin_user()
-      Ash.create!(resource, attrs, actor: admin_user)
-
-  ## Usage in Policies
-
-      policies do

-        # In production: ALL operations denied (fail-closed)

-          authorize_if HasPermission
-        end
-      end
-
-  ## Behavior
-
-  - In test environment: Returns `true` when actor is nil (allows all operations)
-  - In production/dev: Returns `false` when actor is nil (denies all operations - fail-closed)
-  - Returns `false` when actor is present (delegates to other policies)

+
+  ## CSV Import
+
+  The CSV import feature allows administrators to upload CSV files and import members.
+
+  ### File Upload
+
+  Files are uploaded automatically when selected (`auto_upload: true`). No manual
+  upload trigger is required.
+
+  ### Rate Limiting
+
+  Currently, there is no rate limiting for CSV imports. Administrators can start
+  multiple imports in quick succession. This is intentional for bulk data migration
+  scenarios, but should be monitored in production.
+
+  ### Limits
+
+  - Maximum file size: 10 MB
+  - Maximum rows: 1,000 rows (excluding header)
+  - Processing: chunks of 200 rows
+  - Errors: capped at 50 per import

   Settings is a singleton resource - there is only one settings record.
