The current `assembly.GetTypes()` + `GetMethod("FactoryServiceRegistrar")` approach is inherently trim-unsafe, causing factory types (especially static factories) to be trimmed in Blazor WASM apps. The solution creates a `NeatooFactoryRegistrarAttribute` with `[DynamicallyAccessedMembers]` that the trimmer follows, ensuring all factory types survive IL trimming. + +--- + +## Business Requirements Context + +**Source:** [Todo Requirements Review](../todos/trimming-safe-factory-registration.md#requirements-review) + +### Relevant Existing Requirements + +#### Trimming Architecture + +- `docs/trimming.md` and `src/Design/CLAUDE-DESIGN.md` (Critical Rule 2): The generator emits `if (NeatooRuntime.IsServerRuntime)` guards for IL trimming. This proposed change does NOT alter guard emission -- it only changes how `RegisterFactories()` discovers `FactoryServiceRegistrar` methods. Guard behavior is orthogonal and unaffected. + +#### Three Factory Types + +- `src/Design/CLAUDE-DESIGN.md` (Decision Table): All three factory patterns (Class, Interface, Static) must be covered by the fix. Currently: + - Class factories: protected by `[DynamicDependency]` on interface methods (v0.21.1) + - Interface factories: NOT protected (confirmed vulnerable) + - Static factories: NOT protected (the original bug report) + +#### FactoryServiceRegistrar Signature + +- All three renderers generate `internal static void FactoryServiceRegistrar(IServiceCollection services, NeatooFactory remoteLocal)`. The `RegisterFactories()` method discovers these via `assembly.GetTypes()` + `GetMethod()`. This change replaces only the discovery mechanism, not the method signature. + +#### Existing Assembly-Level Attribute Pattern + +- `src/RemoteFactory/FactoryAttributes.cs` (line 129): `FactoryHintNameLengthAttribute` with `[AttributeUsage(AttributeTargets.Assembly)]` already exists. The new attribute follows this pattern. + +#### Auth Type Auto-Registration + +- `src/Design/CLAUDE-DESIGN.md`: The generator emits `services.TryAddTransient()` inside `FactoryServiceRegistrar`. This is preserved as long as `FactoryServiceRegistrar` survives trimming -- which is exactly what this fix ensures. + +#### RegisterMatchingName is Out of Scope + +- `src/RemoteFactory/AddRemoteFactoryServices.cs` (lines 150-154): `RegisterMatchingName` also uses `assembly.GetTypes()` but is a separate user-facing concern. Not in scope for this fix. + +#### Server Registration Path + +- `src/RemoteFactory.AspNetCore/ServiceCollectionExtensions.cs`: `AddNeatooAspNetCore` delegates to `AddNeatooRemoteFactory` which calls `RegisterFactories()`. The fix automatically applies to both client and server paths. + +#### TrimmingTests Direct Call Pattern + +- `src/Tests/RemoteFactory.TrimmingTests/Program.cs` line 14: Calls `TrimTestEntityFactory.FactoryServiceRegistrar()` directly, bypassing `RegisterFactories()`. Should be updated to test the assembly-attribute discovery path as well. + +### Existing Tests + +- `src/Tests/RemoteFactory.TrimmingTests/`: Only tests a class factory (`TrimTestEntity`). No static factory coverage. The trimming test project verifies IL trimming behavior by publishing with `PublishTrimmed=true` and checking that server-only types are removed. +- `src/Tests/RemoteFactory.UnitTests/FactoryGenerator/Visibility/`: Tests verify generated code structure (guard emission, interface visibility). These reference `FactoryServiceRegistrar` as a string marker but don't test the discovery mechanism. + +### Gaps + +1. No unit tests for `RegisterFactories()` discovery mechanism itself. +2. No static factory in the trimming test project (the original bug scenario). +3. Old inline generator path in `FactoryGenerator.cs` (`GenerateExecute` at line 84, class/interface at line 822) is dead code -- `Initialize()` only wires up the Renderer path. Cleanup is separate from this fix. + +### Contradictions + +None. The proposed solution is consistent with all documented patterns. + +### Recommendations for Architect + +1. Place attribute in `src/RemoteFactory/FactoryAttributes.cs` with `#if !NETSTANDARD` guard (file is shared with Generator via `` link; `[DynamicallyAccessedMembers]` is not available on netstandard2.0). +2. Ensure `[DynamicallyAccessedMembers]` on both constructor parameter AND property for end-to-end trimmer tracking. +3. Extend TrimmingTests with a static factory. +4. Assembly attribute emission goes in Renderer classes, not FactoryModelBuilder. +5. Old `FactoryGenerator.cs` inline path is dead code -- do not attempt migration, just leave it (separate cleanup concern). + +--- + +## Business Rules (Testable Assertions) + +1.

Each factory's generated source file gets an `[assembly: NeatooFactoryRegistrar(typeof(FullyQualifiedType))]` before the namespace declaration. This creates a static `typeof()` reference that the trimmer must follow. + +3. **Update `RegisterFactories()`** to enumerate assembly attributes instead of scanning all types. The `GetMethod("FactoryServiceRegistrar")` call on the preserved type is now trim-safe because `[DynamicallyAccessedMembers]` on the attribute guarantees the type's methods are preserved. + +This replaces the v0.21.1 `[DynamicDependency]` workaround on class factory interface methods, which was limited to class factories only. + +--- + +## Design + +### 1. NeatooFactoryRegistrarAttribute + +Location: `src/RemoteFactory/FactoryAttributes.cs`, wrapped in `#if !NETSTANDARD` (since `DynamicallyAccessedMembers` is not available on netstandard2.0, and this file is shared with the Generator project via `` link). + +```csharp +#if !NETSTANDARD +[System.AttributeUsage(AttributeTargets.Assembly, Inherited = false, AllowMultiple = true)] +public sealed class NeatooFactoryRegistrarAttribute : Attribute +{ + public NeatooFactoryRegistrarAttribute( + [DynamicallyAccessedMembers( + DynamicallyAccessedMemberTypes.PublicMethods | + DynamicallyAccessedMemberTypes.NonPublicMethods)] Type type) + { + Type = type; + } + + [DynamicallyAccessedMembers( + DynamicallyAccessedMemberTypes.PublicMethods | + DynamicallyAccessedMemberTypes.NonPublicMethods)] + public Type Type { get; } +} +#endif +``` + +Key design decisions: +- `AllowMultiple = true` -- each factory type gets its own attribute instance +- `[DynamicallyAccessedMembers(PublicMethods | NonPublicMethods)]` on BOTH the constructor parameter AND the property -- this creates the full dataflow contract the trimmer follows. `FactoryServiceRegistrar` is `internal static` (NonPublicMethods) or `public static` (PublicMethods) depending on factory type. +- `#if !NETSTANDARD` -- the Generator (netstandard2.0) emits this attribute as text strings; it doesn't need the type itself at compile time. + +### 2. Assembly Attribute Emission in Renderers + +Each Renderer adds the assembly-level attribute before the namespace declaration in the generated source. The pattern is the same for all three factory types; only the referenced type differs. + +**ClassFactoryRenderer changes:** +- ADD: `[assembly: NeatooFactoryRegistrar(typeof({Namespace}.{ImplementationTypeName}Factory))]` before `namespace` +- ADD: `using Neatoo.RemoteFactory;` for the attribute (if not already present) +- REMOVE: `[DynamicDependency(DynamicallyAccessedMemberTypes.All, typeof({ImplementationTypeName}Factory))]` from interface methods (lines 126-130) +- REMOVE: `using System.Diagnostics.CodeAnalysis;` (only needed for `[DynamicDependency]`) + +**StaticFactoryRenderer changes:** +- ADD: `[assembly: NeatooFactoryRegistrar(typeof({Namespace}.{TypeName}))]` before `namespace` +- ADD: `using Neatoo.RemoteFactory;` for the attribute (if not already present) + +**InterfaceFactoryRenderer changes:** +- ADD: `[assembly: NeatooFactoryRegistrar(typeof({Namespace}.{ImplementationTypeName}Factory))]` before `namespace` +- ADD: `using Neatoo.RemoteFactory;` for the attribute (if not already present) + +The fully-qualified type name is required in the `typeof()` expression because the attribute is at assembly scope (outside the namespace declaration). The qualified name is constructed from `unit.Namespace` + the type name: +- Class factory: `{unit.Namespace}.{model.ImplementationTypeName}Factory` +- Static factory: `{unit.Namespace}.{model.TypeName}` +- Interface factory: `{unit.Namespace}.{model.ImplementationTypeName}Factory` + +### 3. Updated RegisterFactories() + +Location: `src/RemoteFactory/AddRemoteFactoryServices.cs`, method `RegisterFactories()` (lines 123-135). + +Current code: +```csharp +private static void RegisterFactories(this IServiceCollection services, + NeatooFactory remoteLocal, params Assembly[] assemblies) +{ + foreach (var assembly in assemblies) + { + var methods = assembly.GetTypes() + .Select(t => t.GetMethod("FactoryServiceRegistrar", + BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public)) + .Where(m => m != null).ToList(); + + foreach (var m in methods) + { + m?.Invoke(null, [services, remoteLocal]); + } + } +} +``` + +New code: +```csharp +private static void RegisterFactories(this IServiceCollection services, + NeatooFactory remoteLocal, params Assembly[] assemblies) +{ + foreach (var assembly in assemblies) + { + var attributes = assembly.GetCustomAttributes(); + + foreach (var attr in attributes) + { + var method = attr.Type.GetMethod("FactoryServiceRegistrar", + BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public); + method?.Invoke(null, [services, remoteLocal]); + } + } +} +``` + +The `GetMethod()` call is now trim-safe because: +1. `attr.Type` returns a `Type` annotated with `[DynamicallyAccessedMembers(PublicMethods | NonPublicMethods)]` +2. The trimmer follows this annotation and preserves all public and non-public methods on the type +3. `GetMethod("FactoryServiceRegistrar")` on the preserved type will always find the method + +### 4. TrimmingTests Extension + +Add a static factory to `src/Tests/RemoteFactory.TrimmingTests/` to verify the original bug (static factories being trimmed) is fixed: + +**New file: `TrimTestCommands.cs`** +```csharp +[Factory] +public static partial class TrimTestCommands +{ + [Remote, Execute] + private static Task _DoWork(string input, [Service] IServerOnlyRepository repo) + { + return Task.FromResult(repo.DoServerWork(input)); + } +} +``` + +**Update `Program.cs`:** +- Add `AddNeatooRemoteFactory(NeatooFactory.Remote, ...)` call that exercises `RegisterFactories()` (the assembly-attribute path) +- Resolve the static factory delegate to verify it survived trimming +- Keep existing direct `FactoryServiceRegistrar` call as a secondary verification + +### 5. Generated Code Structure + +Example of what a generated class factory file will look like after the change: + +```csharp +#nullable enable + +using Neatoo.RemoteFactory; +using Microsoft.Extensions.DependencyInjection; +// ... other usings ... + +[assembly: NeatooFactoryRegistrar(typeof(MyNamespace.MyEntityFactory))] + +/* + READONLY - DO NOT EDIT!!!! + Generated by Neatoo.RemoteFactory +*/ +namespace MyNamespace +{ + public interface IMyEntityFactory + { + // NO [DynamicDependency] attributes -- removed + Task Create(string name, CancellationToken cancellationToken = default); + } + + internal class MyEntityFactory : IMyEntityFactory + { + // ... factory implementation ... + + public static void FactoryServiceRegistrar(IServiceCollection services, NeatooFactory remoteLocal) + { + // ... registrations ... + } + } +} +``` + +--- + +## Implementation Steps + +### Phase 1: Core Library Changes + +1. Add `NeatooFactoryRegistrarAttribute` to `src/RemoteFactory/FactoryAttributes.cs` inside `#if !NETSTANDARD` block, at the end of the file (after `FactoryHintNameLengthAttribute`). +2. Add `using System.Diagnostics.CodeAnalysis;` to `FactoryAttributes.cs` inside the same `#if !NETSTANDARD` block. +3. Update `RegisterFactories()` in `src/RemoteFactory/AddRemoteFactoryServices.cs` to use `assembly.GetCustomAttributes()` instead of `assembly.GetTypes()`. + +### Phase 2: Generator Renderer Changes + +4. **ClassFactoryRenderer.cs**: Remove `[DynamicDependency]` emission from `RenderFactoryInterface()` (lines 126-130). Remove the `using System.Diagnostics.CodeAnalysis;` emission (lines 51-55). Add assembly-level attribute emission after usings, before namespace. Ensure `using Neatoo.RemoteFactory;` is present. +5. **StaticFactoryRenderer.cs**: Add assembly-level attribute emission after usings, before namespace. Ensure `using Neatoo.RemoteFactory;` is present. +6. **InterfaceFactoryRenderer.cs**: Add assembly-level attribute emission after usings, before namespace. Ensure `using Neatoo.RemoteFactory;` is present. + +### Phase 3: Trimming Tests + +7. Create `src/Tests/RemoteFactory.TrimmingTests/TrimTestCommands.cs` with a static factory using `[Factory]`, `[Remote, Execute]`. +8. Update `src/Tests/RemoteFactory.TrimmingTests/Program.cs` to exercise the assembly-attribute discovery path via `AddNeatooRemoteFactory()` and verify the static factory delegate is resolvable. + +### Phase 4: Unit Test Updates + +9. Add or update unit tests in `src/Tests/RemoteFactory.UnitTests/FactoryGenerator/` to verify: + - Assembly attribute is emitted for class, static, and interface factories + - `[DynamicDependency]` is no longer emitted on class factory interfaces + - `using System.Diagnostics.CodeAnalysis;` is no longer emitted by ClassFactoryRenderer + +### Phase 5: Build and Test + +10. Build the full solution: `dotnet build src/Neatoo.RemoteFactory.sln` +11. Run all tests: `dotnet test src/Neatoo.RemoteFactory.sln` +12. Verify existing unit tests that reference `FactoryServiceRegistrar` as a string marker still pass (these tests search generated source for method names -- the `FactoryServiceRegistrar` method is unchanged, so they should pass). + +--- + +## Acceptance Criteria + +- [ ] `NeatooFactoryRegistrarAttribute` defined in `src/RemoteFactory/FactoryAttributes.cs` with `[DynamicallyAccessedMembers]` on both constructor parameter and property +- [ ] All three Renderer classes (Class, Static, Interface) emit `[assembly: NeatooFactoryRegistrar(typeof(...))]` in generated code +- [ ] `[DynamicDependency]` removed from class factory interface methods in ClassFactoryRenderer +- [ ] `using System.Diagnostics.CodeAnalysis;` removed from ClassFactoryRenderer emission +- [ ] `RegisterFactories()` updated to use `assembly.GetCustomAttributes()` instead of `assembly.GetTypes()` +- [ ] Static factory added to TrimmingTests project +- [ ] TrimmingTests exercises assembly-attribute discovery path +- [ ] Unit tests verify assembly attribute emission for all three factory types +- [ ] Unit tests verify `[DynamicDependency]` is NOT emitted on class factory interfaces +- [ ] Full solution builds with zero errors +- [ ] All existing tests pass + +--- + +## Dependencies + +- `System.Diagnostics.CodeAnalysis.DynamicallyAccessedMembersAttribute` -- available in net9.0 and net10.0 (both target frameworks). NOT available on netstandard2.0 (hence `#if !NETSTANDARD` guard). +- No new NuGet packages required. +- No breaking changes to public API (the attribute is consumed internally by the generator and `RegisterFactories()`). + +--- + +## Risks / Considerations + +1. **Unit test fragility**: Existing unit tests that search generated source for string patterns (e.g., looking for `DynamicDependency`) will need updates. The tests in `CanMethodVisibilityTests.cs` and `InternalVisibilityTests.cs` search for `FactoryServiceRegistrar` as a marker but do not assert `[DynamicDependency]` presence, so they should not break. + +2. **Assembly attribute uniqueness**: Each generated factory file emits its own `[assembly: NeatooFactoryRegistrar(typeof(...))]`. Multiple files can have assembly-level attributes -- the `AllowMultiple = true` on the attribute definition handles this correctly. + +3. **Namespace qualification**: The `typeof()` expression in the assembly attribute must use the fully-qualified type name because the attribute appears at file scope (outside the namespace). This is constructed from `unit.Namespace + "." + TypeName`. If any namespace contains special characters or conflicts, this could produce invalid code. This risk is low since the namespace comes directly from the user's source code. + +4. **Dead code in FactoryGenerator.cs**: The old inline generator path (`GenerateExecute` and class/interface generation in `FactoryGenerator.cs`) is confirmed dead code -- `Initialize()` only wires up the Renderer path. This plan does NOT touch `FactoryGenerator.cs`. Dead code cleanup is a separate concern. + +5. **RegisterMatchingName still uses reflection**: `RegisterMatchingName()` in `AddRemoteFactoryServices.cs` still uses `assembly.GetTypes()`. This is out of scope -- it is a user-facing method for convention-based DI registration, not the factory discovery mechanism. + +6. **Trimming test verification is manual**: The `RemoteFactory.TrimmingTests` project is verified by `dotnet publish` with trimming enabled and checking the output. This is not part of `dotnet test`. The CI/CD pipeline may not exercise this. The developer should verify locally. + +--- + +## Architectural Verification + +**Scope Table:** + +| Factory Pattern | Current Trimming Protection | After This Change | +|----------------|---------------------------|-------------------| +| Class Factory | `[DynamicDependency]` on interface methods (v0.21.1) | `[assembly: NeatooFactoryRegistrar(typeof(XxxFactory))]` | +| Static Factory | NONE (bug) | `[assembly: NeatooFactoryRegistrar(typeof(XxxCommands))]` | +| Interface Factory | NONE (vulnerable) | `[assembly: NeatooFactoryRegistrar(typeof(XxxFactory))]` | + +**Verification Evidence:** + +- Dead code in `FactoryGenerator.cs`: Verified -- `Initialize()` (lines 19-82) only calls `FactoryModelBuilder.Build` + `FactoryRenderer.Render`. `GenerateExecute` (line 84) is never called. +- `FactoryAttributes.cs` shared with Generator: Verified -- Generator.csproj line 16 includes it via ``. The `#if !NETSTANDARD` guard is necessary. +- `DynamicallyAccessedMembersAttribute` availability: Available in `System.Diagnostics.CodeAnalysis` on net9.0 and net10.0. Not available on netstandard2.0. +- `FactoryServiceRegistrar` visibility: Class and interface factories generate it as `public static`. Static factories generate it as `internal static`. The `[DynamicallyAccessedMembers(PublicMethods | NonPublicMethods)]` covers both. + +**Breaking Changes:** No -- the `NeatooFactoryRegistrarAttribute` is new public API but is consumed by generated code, not user code. The `RegisterFactories()` method is private. The `FactoryServiceRegistrar` method signature is unchanged. + +**Codebase Analysis:** + +| File | Purpose | Changes Required | +|------|---------|-----------------| +| `src/RemoteFactory/FactoryAttributes.cs` | Attribute definitions | Add `NeatooFactoryRegistrarAttribute` in `#if !NETSTANDARD` | +| `src/RemoteFactory/AddRemoteFactoryServices.cs` | Factory discovery | Update `RegisterFactories()` to use assembly attributes | +| `src/Generator/Renderer/ClassFactoryRenderer.cs` | Class factory codegen | Remove `[DynamicDependency]`, add assembly attribute | +| `src/Generator/Renderer/StaticFactoryRenderer.cs` | Static factory codegen | Add assembly attribute | +| `src/Generator/Renderer/InterfaceFactoryRenderer.cs` | Interface factory codegen | Add assembly attribute | +| `src/Tests/RemoteFactory.TrimmingTests/TrimTestCommands.cs` | NEW | Static factory for trimming test | +| `src/Tests/RemoteFactory.TrimmingTests/Program.cs` | Trimming verification | Exercise assembly-attribute discovery | +| `src/Tests/RemoteFactory.UnitTests/` | Generator unit tests | Verify attribute emission, verify DynamicDependency removal | + +--- + +## Agent Phasing + +| Phase | Agent Type | Fresh Agent? | Rationale | Dependencies | +|-------|-----------|-------------|-----------|--------------| +| Phase 1: Core library (attribute + RegisterFactories) | developer | Yes | Clean start, small scope (2 files) | None | +| Phase 2: Generator renderers | developer | No | Same agent, continues from Phase 1; needs context of attribute name/namespace | Phase 1 | +| Phase 3: Trimming tests | developer | No | Same agent, continues; needs context of changes made | Phase 1, 2 | +| Phase 4: Unit tests + build verification | developer | No | Same agent; needs full context of all changes | Phase 1, 2, 3 | + +**Parallelizable phases:** None -- each phase depends on the previous. + +**Notes:** All phases are small enough to fit in a single agent session.

Same `[AttributeUsage(AttributeTargets.Assembly)]` pattern. | +| 5 | Auth type auto-registration preserved | SATISFIED | `FactoryServiceRegistrar` method body is unchanged across all three Renderers. InterfaceFactoryRenderer still emits `services.TryAddTransient<{authType}, {concreteType}>()` in its auth registration block (lines 447-472). ClassFactoryRenderer still emits auth registrations. Auth types survive trimming because `FactoryServiceRegistrar` itself now survives via the assembly attribute. | +| 6 | RegisterMatchingName unchanged (out of scope) | SATISFIED | `RegisterMatchingName()` in `src/RemoteFactory/AddRemoteFactoryServices.cs` lines 146-165 is completely unchanged. Still uses `assembly.GetTypes()` for convention-based registration. | +| 7 | Server registration path (AddNeatooAspNetCore) | SATISFIED | `src/RemoteFactory.AspNetCore/ServiceCollectionExtensions.cs` is unchanged. Line 30 delegates to `AddNeatooRemoteFactory(NeatooFactory.Server, ...)` which calls updated `RegisterFactories()`. Transparent. | +| 8 | Design project test infrastructure | SATISFIED | `src/Design/Design.Tests/TestInfrastructure/DesignClientServerContainers.cs` is unchanged. Line 230 calls `AddNeatooRemoteFactory()` which now uses assembly attribute discovery internally. Design.Tests: 41 passed, 0 failed on both net9.0 and net10.0. | +| 9 | TrimmingTests updated to exercise assembly-attribute discovery | SATISFIED | `src/Tests/RemoteFactory.TrimmingTests/Program.cs` line 15 now calls `services.AddNeatooRemoteFactory(NeatooFactory.Remote, typeof(TrimTestEntity).Assembly)` exercising the assembly-attribute path. Line 31 resolves `TrimTestCommands.DoWork` delegate (static factory). Line 28 resolves `ITrimTestEntityFactory` (class factory). New `TrimTestCommands.cs` adds a static factory test target. | +| 10 | Multi-targeting (net9.0 and net10.0) | SATISFIED | Unit tests pass on both TFMs (490 passed each). Integration tests pass on both (481 passed each). Design.Tests pass on both (41 passed each). `[DynamicallyAccessedMembers]` used with fully-qualified `System.Diagnostics.CodeAnalysis.*` inside `#if !NETSTANDARD` guard, available on both frameworks. | +| 11 | No Design Debt conflict | SATISFIED | No features from the Design Debt table were implemented. No deferred decisions were overridden. The change is strictly an infrastructure improvement to the factory discovery mechanism. | + +### Pre-Design Review Gap Resolution + +| Gap (from pre-design review) | Resolution | +|-------------------------------|------------| +| No unit tests for `RegisterFactories()` | ADDRESSED: New `AssemblyAttributeEmissionTests.cs` with 5 tests verifying assembly attribute emission for all three factory types. Integration tests exercise the full `RegisterFactories()` path via `AddNeatooRemoteFactory()` (481 tests, all passing). | +| No static factory in TrimmingTests | ADDRESSED: New `TrimTestCommands.cs` added with `[Factory]`, `[Remote, Execute]` static factory. `Program.cs` updated to resolve `TrimTestCommands.DoWork` delegate. | +| Generator dual-path clarification | CONFIRMED: Old inline path in `FactoryGenerator.cs` is dead code. Plan correctly identified this and excluded it from scope. No changes to `FactoryGenerator.cs`. | +| Published docs update for `[DynamicDependency]` | NO ACTION NEEDED: The `[DynamicDependency]` reference in `docs/trimming.md` line 215 is user-facing guidance for `RegisterMatchingName` (preserved types from convention-based registration), not about internal factory interface methods. The reference remains accurate. | + +### Unintended Side Effects + +None detected. Specifically verified: + +1. **Generated code structure**: The only differences in generated output are (a) addition of `[assembly: NeatooFactoryRegistrar(...)]` before namespace, (b) removal of `[DynamicDependency]` on class factory interface methods, (c) removal of `using System.Diagnostics.CodeAnalysis;` from class factory output. No behavioral changes to factory interfaces, delegates, service registration, guard emission, or authorization handling. + +2. **Serialization contracts**: No serialization-related code was modified. `IOrdinalSerializable` implementation, property setters, round-trip behavior are all unchanged. + +3. **Factory interface visibility**: `RenderFactoryInterface()` in ClassFactoryRenderer still uses the same visibility logic (lines 109-127). The only change is removal of the `[DynamicDependency]` prefix on interface method lines. Interface promotion of `[Remote] internal` methods is unaffected. + +4. **Published documentation accuracy**: `docs/trimming.md` and `src/Design/CLAUDE-DESIGN.md` remain accurate. Neither references `[DynamicDependency]` on factory interfaces as an internal mechanism. The `docs/trimming.md` reference to `[DynamicDependency]` (line 215) is about user-facing `RegisterMatchingName` guidance and is unrelated. + +5. **Design project source of truth**: No files in `src/Design/` were modified.

The dotnet-runtime-debugger agent confirmed that `[DynamicallyAccessedMembers(PublicMethods | NonPublicMethods)]` on both the constructor parameter AND the property creates a dataflow contract the trimmer follows. The downstream `GetMethod()` call becomes trim-safe with no warnings. The annotation must appear on both sides (constructor param and property) for end-to-end trimmer tracking. + +### Q3: `using System.Diagnostics.CodeAnalysis;` cleanup (Architect) +**Q:** Should we remove the `using System.Diagnostics.CodeAnalysis;` from ClassFactoryRenderer when removing `[DynamicDependency]`? +**A:** Yes, do the cleanup. Remove it since it was only added for `[DynamicDependency]`. + +### Q4: InterfaceFactoryRenderer vulnerability (Architect) +**Q:** Does InterfaceFactoryRenderer have the same trimming problem as static factories? +**A:** Yes. The dotnet-runtime-debugger agent confirmed interface factories ARE vulnerable. The trimmer preserves the type and its interface-contract methods via DI, but `FactoryServiceRegistrar` is `internal static`, satisfies no interface, and has no static callers — so it gets trimmed. All three factory types need the fix. + +**Architect confirmed: Ready to proceed.** + +--- + +## Requirements Review + +**Reviewer:** business-requirements-reviewer +**Reviewed:** 2026-03-08 +**Verdict:** APPROVED + +### Relevant Requirements Found + +1. **Trimming architecture (feature switch guards).** `docs/trimming.md` and `src/Design/CLAUDE-DESIGN.md` (Critical Rule 2, "Factory Method Visibility Controls Guard Emission and Trimming") document that the generator emits `if (NeatooRuntime.IsServerRuntime)` guards and that these are the mechanism for IL trimming. The proposed change does not alter guard emission — it only changes how `RegisterFactories()` discovers the `FactoryServiceRegistrar` methods. The guard behavior is orthogonal and unaffected. + +2. **Three factory types must all be covered.** `src/Design/CLAUDE-DESIGN.md` (Decision Table, Quick Reference) documents Class, Interface, and Static factory patterns. The todo correctly identifies that all three need the fix. Confirmed in the Renderer code: + - `src/Generator/Renderer/ClassFactoryRenderer.cs` — currently emits `[DynamicDependency]` on interface methods (lines 126-130) + - `src/Generator/Renderer/StaticFactoryRenderer.cs` — has no trimming protection (confirmed: no `DynamicDependency` anywhere in file) + - `src/Generator/Renderer/InterfaceFactoryRenderer.cs` — has no trimming protection (confirmed: no `DynamicDependency` anywhere in file) + +3. **`FactoryServiceRegistrar` is generated with consistent signatures.** All three renderers generate an `internal static void FactoryServiceRegistrar(IServiceCollection services, NeatooFactory remoteLocal)` method. The `RegisterFactories()` method in `src/RemoteFactory/AddRemoteFactoryServices.cs` (line 127) discovers these via `assembly.GetTypes()` + `GetMethod("FactoryServiceRegistrar", BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public)`. The proposed change replaces only the discovery mechanism, not the generated method signature or behavior. + +4. **Existing assembly-level attribute pattern.** `src/RemoteFactory/FactoryAttributes.cs` (line 129) already has `FactoryHintNameLengthAttribute` with `[AttributeUsage(AttributeTargets.Assembly)]`. The proposed `NeatooFactoryRegistrarAttribute` follows this established pattern. No contradiction. + +5. **Auth type auto-registration for trimming.** `src/Design/CLAUDE-DESIGN.md` ("Auth Type Auto-Registration for Trimming") documents that the generator emits explicit `services.TryAddTransient()` in `FactoryServiceRegistrar`. This pattern is inside the `FactoryServiceRegistrar` method body, so it is preserved as long as the `FactoryServiceRegistrar` method itself survives trimming — which is exactly what the proposed fix ensures. + +6. **`RegisterMatchingName` uses `assembly.GetTypes()` too.** `src/RemoteFactory/AddRemoteFactoryServices.cs` (lines 150-154) has a separate `RegisterMatchingName` method that also uses `assembly.GetTypes()`. The todo's scope correctly limits the fix to `RegisterFactories()` only. `RegisterMatchingName` is user-called for convention registration and is a separate concern documented in `docs/trimming.md` (lines 208-215). + +7. **Server setup via `AddNeatooAspNetCore`.** `src/RemoteFactory.AspNetCore/ServiceCollectionExtensions.cs` (line 30) delegates to `services.AddNeatooRemoteFactory(NeatooFactory.Server, ...)`, which calls `RegisterFactories()`. The proposed change to `RegisterFactories()` will automatically apply to both client (`AddNeatooRemoteFactory`) and server (`AddNeatooAspNetCore`) registration paths. No additional changes needed. + +8. **Design project test infrastructure.** `src/Design/Design.Tests/TestInfrastructure/DesignClientServerContainers.cs` (line 230) calls `services.AddNeatooRemoteFactory(mode, serializationOptions, typeof(ExampleClassFactory).Assembly)`, which internally calls `RegisterFactories()`. The proposed change will be transparent to this call chain. + +9. **TrimmingTests project.** `src/Tests/RemoteFactory.TrimmingTests/Program.cs` calls `TrimTestEntityFactory.FactoryServiceRegistrar(services, NeatooFactory.Remote)` directly (line 14), bypassing `RegisterFactories()`. This direct call pattern will continue to work since the `FactoryServiceRegistrar` method signature is unchanged. However, this test should be updated or extended to verify that the assembly-attribute-based discovery also works. + +10. **Multi-targeting requirement.** `src/Directory.Build.props` targets net9.0 and net10.0. The proposed `NeatooFactoryRegistrarAttribute` and `[DynamicallyAccessedMembers]` are available in both target frameworks. `[FeatureSwitchDefinition]` (used by the existing trimming infrastructure) was introduced in .NET 9, confirming both TFMs are compatible. + +11. **No Design Debt conflict.** The Design Debt table in `src/Design/CLAUDE-DESIGN.md` lists five deferred topics (private setter support, OR logic for AspAuthorize, automatic Remote detection, collection factory injection, IEnumerable serialization). None relate to factory registration or trimming discovery. No conflict. + +### Gaps + +1. **No existing unit tests for `RegisterFactories()`.** There are no tests in `src/Tests/RemoteFactory.UnitTests/` that verify the `RegisterFactories()` method's behavior. The architect should include tests that verify assembly-attribute-based discovery works for all three factory types (class, static, interface). + +2. **No integration test for static factory trimming.** The `src/Tests/RemoteFactory.TrimmingTests/` project only tests a class factory (`TrimTestEntity`). The architect should consider adding a static factory to this project to verify the fix addresses the original bug (static factories being trimmed). + +3. **Generator pipeline dual-path clarification.** The todo's Q1 states "Both paths are active" (FactoryGenerator.cs inline and Renderer classes). However, inspection of `FactoryGenerator.cs` shows that `GenerateExecute` (line 84) and the class/interface generation (line 822) are defined but **not called from `Initialize()`**. The `Initialize()` method (lines 19-81) only wires up the Renderer path via `FactoryModelBuilder.Build` + `FactoryRenderer.Render`. The old inline methods appear to be dead code. The architect should verify this before attempting to "remove or migrate" the old path — it may already be dead. + +4. **Published docs update needed.** `docs/trimming.md` (line 215) recommends `[DynamicDependency]` as a user-facing option for preserving types. If the library moves to assembly-level attributes internally, the docs should still accurately describe the available user-facing options. The internal mechanism change should not require docs updates, but if the `[DynamicDependency]` on factory interface methods is removed, verify this doesn't break any documented guidance. + +### Contradictions + +None found. The proposed solution is consistent with all documented patterns, rules, and design decisions. + +### Recommendations for Architect + +1. **Verify the old FactoryGenerator.cs inline path is dead code.** The `GenerateExecute` method (line 84) and class/interface generation (line 822) in `FactoryGenerator.cs` are not called from `Initialize()`. If they are indeed dead, the Q1 clarification to "remove the old inline path" is simply dead code cleanup, not a migration. Confirm before spending effort on migration. + +2. **Place `NeatooFactoryRegistrarAttribute` in `src/RemoteFactory/FactoryAttributes.cs`.** This file already contains all factory-related attributes including the existing assembly-level `FactoryHintNameLengthAttribute`. Follow the established pattern. + +3. **Ensure `[DynamicallyAccessedMembers]` is on both constructor parameter AND property.** The Q2 clarification specifies this dual annotation requirement. This is critical for end-to-end trimmer tracking. + +4. **Extend TrimmingTests with a static factory.** The original bug specifically affects static factories. The trimming test project should include a static factory to prevent regression. + +5. **The assembly attribute emission should be in the Renderer classes, not in `FactoryModelBuilder`.** Keep the Renderers as the sole code-generation path, consistent with the current architecture where `FactoryModelBuilder` builds models and Renderers produce output. + +6. **Consider the `TrimTestEntity` direct call pattern.** `src/Tests/RemoteFactory.TrimmingTests/Program.cs` line 14 calls `FactoryServiceRegistrar` directly. This bypasses `RegisterFactories()` entirely. If the goal is to test the full registration pipeline, the test should be updated to call `AddNeatooRemoteFactory()` instead. + +--- + +## Plans + +- [Trimming-Safe Factory Registration Plan](../plans/completed/trimming-safe-factory-registration.md) + +--- + +## Tasks + +- [x] Architect comprehension check (Step 2) +- [x] Business requirements review (Step 3) +- [x] Architect plan creation & design (Step 4) +- [x] Developer review (Step 5) +- [x] Implementation (Step 7) +- [x] Verification (Step 8) +- [x] Documentation (Step 9) +- [x] Completion (Step 10) + +--- + +## Progress Log + +### 2026-03-08 +- Created todo from bug report: static factories (e.g., TherapyCommands) trimmed in Blazor WASM apps +- v0.21.1 fix addressed class factories but not static factories +- dotnet-runtime-debugger agent confirmed `[DynamicDependency]` is not valid on delegates (CS0592) +- Agent recommended assembly-level attribute with `[DynamicallyAccessedMembers]` as the proper fix + +--- + +## Completion Verification + +Before marking this todo as Complete, verify: + +- [x] All builds pass +- [x] All tests pass + +**Verification results:** +- Build: Pass (Release mode, 0 errors) +- Tests: Pass (2,024 tests: 490×2 unit + 481×2 integration + 41×2 design, 0 failures) + +--- + +## Results / Conclusions + +Replaced the trim-unsafe `assembly.GetTypes()` factory discovery with a `NeatooFactoryRegistrarAttribute` assembly-level attribute pattern.
