- Document every endpoint's responses (Produces<T>/status codes/validation)
so the generated OpenAPI/Scalar docs carry response schemas and status codes
instead of empty responses
- Cache recently-synced user ids (IMemoryCache, 15 min) in the JWT
TokenValidated handler so user provisioning no longer hits the DB on every
authenticated request
- Add ProblemDetails + UseExceptionHandler for consistent RFC7807 errors
- Add ToCreatedResult ErrorOr helper and use it in the create endpoints
- Normalize the playlists route to lowercase (/playlists)
Verified: booted the Api against RabbitMQ + Postgres in Docker and inspected
/openapi/v1.json — operations now expose response schemas/status codes and the
route is /playlists.
Build: 0 warnings, 0 errors.
Single docker-compose stack for local development (Postgres, Zitadel,
RabbitMQ, SeaweedFS + bucket init, Jaeger) plus an optional overlay to run
the .NET apps in Docker. up.ps1 orchestrates the full bootstrap: stack up,
stream-ticket keys, EF Core migrations and Zitadel provisioning.
- Zitadel is provisioned automatically (service-account PAT -> project +
OIDC app with JWT access token); the generated ClientId is wired into
Musify.Api user-secrets and .env. No manual console steps.
- ZITADEL_EXTERNAL_DOMAIN=host.docker.internal so token validation works
both with local apps and full-docker.
- App Dockerfiles copy AppSettings*.json to lowercase so config loads on
case-sensitive Linux; Worker image ships ffmpeg.
- Scripts split by responsibility (common/stream-keys/migrate/provision);
apps overlay de-duped via YAML anchors.
- Remove the superseded standalone seaweedfs compose; point docs/development
at the unified stack.
Register AuditableEntityInterceptor as a singleton and attach it through the
AddDbContext options callback instead of newing it up inside
Database.OnConfiguring. The interceptor is stateless, so a single shared
instance is reused across contexts and its wiring lives in the DI layer.
The design-time factory keeps working (interceptor is runtime-only, irrelevant
for migrations).
Verified: build + ef migrations list (design-time context) OK; the Worker host
builds and validates the full DI graph (reaches endpoint configuration) with no
captive-dependency or interceptor error.
Build: 0 warnings, 0 errors.
- Register IAmazonS3 as a singleton instead of scoped: the AWS SDK client is
thread-safe and manages its own connection pool, so one instance per DI scope
(per request / per job iteration) was wasteful and risked socket exhaustion
- AudioTranscoderService: start reading stdout/stderr before writing stdin to
remove the latent pipe-buffer deadlock shape
- Dispose the resized-picture MemoryStream in ResizePictureActivity
- Background jobs use PeriodicTimer instead of while + Task.Delay
Verified: Worker boots against RabbitMQ + Postgres in Docker with no captive-
dependency error (dev scope validation) and both jobs start.
Build: 0 warnings, 0 errors.
Adds the PlayList picture-processing lifecycle saga (correlated by PlayListId)
mirroring the track one, and generalizes the failure plumbing:
- Rename the track fault translator to ProcessingSlipFaultConsumer and use a
generic Workflow.SubjectId variable + ProcessKind; it now emits typed
Track{Picture,Audio}/PlayListPicture ProcessingFailed events for all slips
- PlayListProcessingStateMachine (+ EF-persisted PlayListProcessingState,
migration): starts on CreatePlayListResourcesEvent, finalizes on
PlayListPictureProcessed, and on failure marks the playlist Failed and
removes the orphaned final picture (PlayListProcessingFailedConsumer +
MarkPlayListAsFailedActivity)
- UpdatePlayListPictureActivity publishes PlayListPictureProcessed on success
- Picture slip carries SubjectId + PlayListPicture kind + fault subscription
Verified end-to-end in Docker (RabbitMQ + migrated Postgres): both saga
endpoints, the fault translator and cleanup consumers configure, and an
addressing cross-check confirms all 21 activity execute queues the builders
address exist (caught + fixed a kebab mismatch on mark-play-list-as-failed).
Build: 0 warnings, 0 errors.
On definitive failure of the picture or audio slip, the saga now reaches a
Failed state and recovers end-to-end:
- Picture/audio track slips carry TrackId + ProcessKind variables and a
subscription to a fault translator (TrackProcessingSlipFaultConsumer) that
turns RoutingSlipFaulted into a typed Track{Picture,Audio}ProcessingFailed
- The saga stores the final object keys from the start event and, on failure,
transitions to Failed and publishes TrackProcessingFailed
- TrackProcessingFailedConsumer runs a cleanup slip that removes the orphaned
final picture/audio copies and marks the track LifeCycleStatus=Failed
(MarkTrackAsFailedActivity) — the track stays as a visible, recoverable record
- Migration for the new saga columns
Verified: Worker boots against RabbitMQ + Postgres in Docker; the new
endpoints (fault translator, failed consumer, mark-track-as-failed) configure
and the bus starts clean.
Build: 0 warnings, 0 errors.
Introduce a MassTransit saga state machine that correlates by TrackId and
tracks the two parallel processing slips (picture + audio):
- TrackProcessingStateMachine + EF-persisted TrackProcessingState
(pessimistic concurrency, EntityFrameworkRepository), migration added
- Starts on CreateTrackResourcesEvent; UpdateTrack{Picture,Audio}Activity now
publish TrackPictureProcessed / TrackAudioProcessed on success; when both
arrive the saga finalizes (Ready). Failure transitions to a Failed state
(cleanup wired in the next phase)
- Add LifeCycleStatus.Failed and the four outcome events
Verified: booted the Worker against RabbitMQ + migrated Postgres in Docker;
the saga endpoint 'track-processing-state' is configured and the bus starts
clean.
Build: 0 warnings, 0 errors.
Replace ~240 lines of hand-written per-endpoint wiring with MassTransit's
ConfigureEndpoints + KebabCaseEndpointNameFormatter, and apply retry + EF
outbox globally through AddConfigureEndpointsCallback. Adding a consumer or
activity is now a single AddConsumer/AddActivity line.
- Normalize the 4 mismatched activity endpoint names to kebab-case so the
routing-slip addressing keeps resolving (update-play-list-picture,
delete/mark/publish play-list variants); cleanup consumer queue is now
routing-slip-clean-up
- Drop the now-unused QueueName consts from event consumers and trim
EndpointHelper / delete the manual endpoint-config partial
Verified end-to-end: booted the Worker against RabbitMQ in Docker and
confirmed all 38 endpoints are configured with the exact names the builders
address (19 execute queues + compensations + consumers + routing-slip-clean-up).
Build: 0 warnings, 0 errors.
Fix (recoverability bug):
- TransferFilesToBucketActivity returned Completed() with no log, so its
compensation could never delete the transferred files (orphaned objects on
fault). IStorageService.TransferFilesAsync now returns the real uploaded
keys; the activity logs them so Compensate can remove them. Also drops the
Path.Combine key recomputation (produced backslash keys on Windows).
Consistency / DRY:
- Normalize all courier activities to internal + folder-based namespaces
(several were public and in the flat .Activities namespace)
- Extract the duplicated exponential retry into UseStandardRetry
- Unify endpoint-name logic into a single EndpointHelper (remove the parallel
MassTransitEndpointNames helper)
Build: 0 warnings, 0 errors.
- Add Musify.Application.AddApplication(services, config) as the layer's DI
entry point: registers Mediator, UploadIntentValidator and all app configs
- Collapse the 5 near-identical AddXConfiguration methods into a single
generic AddValidatedOptions<T>(config, section)
- Move UploadIntentValidator registration out of Infrastructure into the
Application layer (fixes layering leak); Infra config binding now uses the
generic helper
- Api calls AddApplication; Worker uses AddValidatedOptions for its configs
Build: 0 warnings, 0 errors.
One file per use case under the feature folder (Tracks/PlayLists/Users),
dropping the Commands/Queries/Handlers sub-folders and their namespaces.
Each file now holds the record and its handler in namespace
Musify.Application.<Feature>; external usings updated accordingly.
Build: 0 warnings, 0 errors.
Ardalis Result<T> carried incoherent success sub-statuses and a clunky
generic converter; ErrorOr models success-or-errors cleanly.
- Application: all commands/queries/handlers now return ErrorOr<T>
(non-generic Result -> ErrorOr<Success>); errors via Error.NotFound/
Conflict/Validation/Unauthorized/Failure; success via value or new Success()
- Drop ResultExtensions.As<>(): error propagation is now just return .Errors
- Rewrite HTTP mapping (ErrorOrHttpExtensions) off Error.Type; success maps
to 200 (value) or 204 (Success); Created still built in the endpoints
- Endpoints/gateway middleware: !IsSuccess -> IsError
- Swap Ardalis.Result package for ErrorOr 2.1.1 (remove unused ref from Worker)

Run autoskills in backend/: detects .NET/C#/ASP.NET Core/Minimal API and
installs 13 skills for universal (.agents) and claude-code (.claude) agents,
with backend/skills-lock.json. Adds ASP.NET Core, Minimal API + OpenAPI,
file-upload and containerization skills on top of the prior C#/.NET set.
Removes the stale root skills from the old layout.
- Move all .NET (6 projects, solution, Directory.*.props, nuget.config)
into backend/ so the monorepo root can host non-.NET projects later
- Remove throwaway test artifacts: player.html, pl.json
- Trim dead Flutter rules from .gitignore
Build from backend/Musify.slnx: 0 warnings, 0 errors.
- Add Directory.Packages.props (CPM): all package versions centralized,
remove Version attributes from every PackageReference
- Add Directory.Build.props: shared TargetFramework/Nullable/ImplicitUsings
- Drop redundant per-project RootNamespace/AssemblyName (default = project name)
and stale NuGet metadata (PackageId/Version/Authors/RepositoryUrl)
- Bump Microsoft.OpenApi to 2.9.0 (CVE-2026-49451, was transitive 2.0.0);
add explicit reference in Musify.Api which uses it directly
- Add repo-scoped nuget.config pinning nuget.org for reproducible restore
Build: 0 warnings, 0 errors.
Groups Domain/Application/Infrastructure under Core and
WebApi/Worker/StreamingGateway under Hosts. Removes the per-repo
.slnx files now superseded by the single solution.
