This design violates our architecture design, the rest endpoint must not directly reference the services but use decoupled use case classes that control the process. HARD REJECT.
Envision an IUseCaseBase interface, and define a layer with pairs of ICreateDoujinUseCase and CreateDoujinUseCase for each action we want to have, including creation, editing, retrieving, and deleting
Without such an abstraction, you run into the risk in which the rest adapter is having a very strong influence on the shape and structure of the internal business logic of the app core.
Please consider adding more documentation to the dtos and endpoints in order to have more meaningful openapi and scalar descriptions for the future
While the integration tests is awesome, the individual app core classes should still be covered to 100% vial unit tests using mocks. Particular for branch coverage that is important

1.
backend/src/DoujinManager.RestAdapter/Endpoints/*.cs— Architecture violation: endpoints directly injectIDoujinServiceAll endpoint classes inject
IDoujinServiceand call it directly:As @bjoern stated in comment #78, the architecture requires decoupled use case classes that control the process — not direct service references from the REST adapter. This PR must be re-architected to use use-case/command classes (e.g.,
CreateDoujinUseCase,ListDoujinsQuery) as the application layer boundary, with the REST adapter delegating to those rather than toIDoujinServicedirectly.2.
backend/src/DoujinManager.Infrastructure/Services/DoujinService.cs:314–376—AssignTag/AssignPerson/AssignCirclealways returntrue, making endpoint 404 paths dead codeAll three assign methods return
boolbut unconditionally returntrue:The endpoints rely on the return value to distinguish 404 from success:
Since
okis alwaystrue, theNotFoundbranch is unreachable. If a non-existent doujin or tag ID is passed,SaveChangesAsyncthrowsDbUpdateException(FK violation), which the global exception middleware converts to a 500 — instead of the intended 404.Suggested fix: Verify that the doujin and the referenced entity (tag/person/circle) exist before inserting the join record. Return
false(orServiceResult.NotFound) if either is missing. Apply toAssignTagAsync,AssignPersonAsync,AssignCircleAsync.3.
backend/src/DoujinManager.RestAdapter/Endpoints/MetadataEndpoints.cs:1078–1099andVariantEndpoints.cs:1197— Metadata list endpoints report wrong pagination totalsListTagsAsync,ListPeopleAsync, andListCirclesAsyncreturnList<T>without a total count. The endpoints then fabricatePageInfowithTotalItems = data.Count:For
VariantEndpointsthe issue is worse — the page size is set todata.Count:This makes pagination metadata incorrect for all metadata endpoints:
totalItemsreflects only the current page's item count, andtotalPagesis always 1.Suggested fix: Have the service methods return
(List<T> Items, int Total)likeListDoujinsAsyncalready does, and computetotalPages = (int)Math.Ceiling(total / (double)pageSize).🟡 Minor (non-blocking)
4.
DoujinService.cs:504–517—CreateTagAsyncdoesn't check for duplicate normalized namesUnlike
CreateDoujinAsync(which normalizes and looks up existing tags before creating),CreateTagAsyncblindly creates a new tag. If a tag with the sameNormalizedNamealready exists, this will either create a duplicate or throw a unique constraint violation (depending on DB constraints). Suggested fix: Look up byNormalizedNamefirst, or return aServiceResult<Tag>withConflictif it exists.5.
DoujinService.cs:409–426—UpdateVariantAsyncreusesCreateVariantRequestwhereLanguageCodeis non-nullableThe
UpdateVariantDto.LanguageCodeisstring?, but it's mapped toCreateVariantRequest(string LanguageCode, ...)whereLanguageCodeis non-nullable. The checkif (req.LanguageCode is not null)is always true, so the language code is always overwritten — even when the client didn't intend to change it (the DTO sends the original value or null, but null can't be distinguished from "no change"). Suggested fix: Use a dedicatedUpdateVariantRequesttype with nullable fields, or document the PATCH-like semantics.6. No input validation on DTOs — No
[Required],[StringLength],[Range]attributes or FluentValidation. Empty strings for names, out-of-range ratings, or empty titles are silently accepted or cause exceptions. Consider adding validation, especially forCreateDoujinDto,CreateTagDto,CreatePersonDto,CreateCircleDto.7. Missing XML doc comments on DTOs and endpoints — As @bjoern requested in comment #79, adding
/// <summary>docs to DTOs and endpoint groups will improve OpenAPI/Scalar documentation.8.
DoujinService.cs:528–543, 568–583—CreatePersonAsync/CreateCircleAsynccall.Trim()ondisplayNamewithout null check — While the DTO type isstring(non-nullable), JSON deserialization edge cases could produce null. No explicit validation guards against this.✅ What looks good

HARD REJECT., even worse You didn't do anything differently on a principle level. The use cases are meant to decouple the primary adapter from the app core. So instead of HTTP Endpoint -> Service(BL), we want to have HTTP Endpoint -> Usecase(potentially having access to all kind of internal services) -> Each Service (BL).
What you did is simply cutting up the DoujinService service and spreading it into use cases. That is never what I asked for. It is still true that the Rest endpoint do call directly into the business logic, in fact it is even worsen ow because we now have truly the point where the shape of the app core matches the needs of the rest adapter.
Think about this scenario as an example of what an use case should be:
1-Usecase add artist -> IAddArtistToDoujinUseCase -> AddArtistToDoujinUseCase(ArtistService, DoujinService)
The use case is an orchestrator, or delegator, and yes to some degree there is some business logic contained in that, but also a clear responsibility. The use case SHOULD NOT know or take on the responsibilities of the inner services of the app core. Yes, for some usecases that literally speak to only one service it feels like bloat, but it decouples the software fundamentally. Once we have use cases that handle tasks spanning multiple services, we then will see the benefits.
I would suggest recreating the DoujinService in a similar shape like before, and design it so that it only serves its OWN needs, and have the use cases call into the
You're absolutely right — I misunderstood the pattern. I simply split the monolithic service into use cases that still directly access EF Core, which means the REST adapter is still effectively calling into business logic. That's worse, not better.
The correct architecture:
Services own their domain logic, designed around their own needs (not the REST adapter's):
DoujinService— CRUD for doujins and their direct relationshipsTagService— tag CRUD, normalization, lookupPersonService— person CRUDCircleService— circle CRUDVariantService— variant CRUDChapterService— chapter CRUDUse cases are thin orchestrators that inject services and coordinate:
CreateDoujinUseCase(DoujinService, TagService, PersonService, CircleService)— creates doujin via DoujinService, creates/looks up tags via TagService, etc.AddArtistToDoujinUseCase(PersonService, DoujinService)— checks person exists via PersonService, checks doujin exists via DoujinService, asks DoujinService to addCreateDoujinUseCase(DoujinService)— simple delegation for single-service casesThe REST adapter keeps injecting use case interfaces — that part stays. But the use case implementations change from directly accessing
DoujinManagerDbContextto injecting and calling services.Reworking now on this branch. The endpoints, DTOs, envelope types, and integration tests should mostly survive — the change is underneath.
Corrected architecture in commit
836746f. The use cases are now thin orchestrators that delegate to domain services.What changed

1.
CreateDoujinUseCase.cs:30–40— Silently skips non-existent person/circle IDsSame pattern for
CircleIds. If a client sends a person or circle ID that doesn't exist, the use case silently skips it. The response returns201 Createdwith a doujin missing those associations — no error, no warning. The client has no way to know the operation partially failed. Suggested fix: Return aServiceResult<Doujin>withBadRequestlisting the invalid IDs, or include awarningsfield in the response.2.
CreateDoujinUseCase.cs:13–54— No transaction wrapping multi-step createThe use case calls multiple services that each call
SaveChangesAsyncindependently:doujinService.CreateAsync()→ SaveChangesAsync (committed)doujinService.AddTitleAsync()× N → SaveChangesAsync each (committed)tagService.GetOrCreateByNameAsync()× N → SaveChangesAsync each (committed)doujinService.AssignTagAsync()× N → SaveChangesAsync each (committed)If any step fails mid-way (e.g., after creating the doujin and 2 titles, but before assigning tags), the doujin is left in a partially initialized state in the database. The client receives a 500 error, retries, and creates a duplicate doujin. Suggested fix: Wrap the entire use case body in
IDbContextTransactionor add aIUnitOfWork/SaveChangesAsyncpattern where services don't commit individually and the use case controls the transaction boundary.3.
VariantEndpoints.cs:12–22andVariantEndpoints.cs:117–122— List endpoints don't verify parent existsListVariantsUseCaseandListChaptersUseCasedon't check if the parent (doujin/variant) exists before querying. If the parent doesn't exist, they return an empty list →200 OKwith empty collection. This is inconsistent withGET /api/doujins/{id}which returns404for a non-existent doujin. Suggested fix: Check parent existence in the use case and return404if missing, or document that these endpoints always return 200.4.
VariantService.cs:74–78— SettingIsDefaulttofalseis silently ignoredThe
UpdateVariantCommand.IsDefaultisbool?, but onlytruehas an effect. If a client sendsisDefault: falseto unset the default flag, nothing happens. This is an undocumented asymmetry. Suggested fix: Either handlefalse(setvariant.IsDefault = false), or document that un-setting default is not supported via update.5.
ChapterService.cs:23— Race condition on auto sort order (TOCTOU)If two chapters are created concurrently for the same variant with null
sortOrder, both compute the same count and get the same sort order. Suggested fix: Use a database sequence, aMAX(SortOrder)+1query, or a unique constraint on(VariantId, SortOrder).6.
CreateDoujinUseCase.cs:54— Null-forgiving operator on GetByIdAsyncIf the doujin was deleted between
CreateAsyncandGetByIdAsync(race condition), this throwsNullReferenceExceptionduring DTO mapping. Suggested fix: Handle null with a fallback or error.7. No input validation on DTOs (previously #6, still open)

1.
DoujinDtos.cs/MetadataDtos.cs(commitaef43c3) — Validation attributes are NOT enforced at runtime; they only decorate the OpenAPI schemaThe commit message itself states: "Runtime validation available if
AddValidation()is registered." I confirmedAddValidation()(or any equivalent —IEndpointFilter,Validator.TryValidateObject, MVC[ApiController], FluentValidation, MiniValidation) is never registered anywhere inProgram.csorRestAdapterExtensions.cs. For minimal APIs (MapPost/MapPuton .NET 10),System.ComponentModel.DataAnnotationsattributes do not auto-validate the request body — they only flow into OpenAPI schema generation.Concretely, this means a client can still POST:
…and it will be accepted and processed, bypassing every
[Range(1,10)]/[StringLength(10, MinimumLength=2)]/[Required]constraint.This isn't a bug per se — the attributes are genuinely useful for OpenAPI/Scalar documentation — but the framing as "input protection" oversells what's delivered. To actually enforce these at runtime, the cheapest fix is a one-line endpoint filter or registering
AddValidation()from a validation package (e.g.,Microsoft.AspNetCore.Components.DataAnnotations.Validationor a community minimal-API validation filter). If enforcement is intentionally deferred, I'd suggest a code comment or XML doc on each DTO stating "schema-only, not runtime-enforced" so future maintainers don't assume the constraints protect against bad input.2.
VariantService.cs:74-85— Un-settingisDefaultcan leave a doujin with zero default variantsThe fix in
74830a7correctly handlesisDefault == false, but there's no guard against the case where the variant being un-set is the only default variant for its doujin. After the update,variant.IsDefault = falseis saved and the doujin now has no default variant. I checkedVariant.csand the domain model has no invariant requiring "exactly one default," so this isn't a contract violation — but it may be a business-rule gap worth a conscious decision: either reject un-setting the last default (returnBadRequest/Conflict), or document that "no default" is an allowed state. If "no default" is intentional, no action needed.3. No test exercises the validation paths (non-blocking, since they're currently schema-only)
The 12 integration tests cover happy paths, 404s, and auth, but none POST an out-of-range rating, empty required field, or oversized string to assert a 400. If finding #1 is addressed by enabling runtime validation, add a few negative tests (e.g.,
Create_With_Invalid_Rating_Returns400,Create_With_Empty_Title_Value_Returns400) so the constraints are actually verified by CI. Low priority now.Summary
Incremental, well-structured commits that cleanly address the prior minor findings. The only substantive observation is that the new validation attributes document constraints without enforcing them — worth either wiring up runtime enforcement or clarifying in docs/comments. No blocking issues. As noted in prior reviews, this is a PR conversation comment, not a formal Forgejo approval (the current MCP integration cannot create review approval states).
