Moves the six backend projects on disk into Core/ and Hosts/
subfolders, matching the solution folders already defined in
Musify.slnx, so the file explorer reflects the same layout as the
solution:
backend/Core/Musify.Domain
backend/Core/Musify.Application
backend/Core/Musify.Infrastructure
backend/Hosts/Musify.Api
backend/Hosts/Musify.Worker
backend/Hosts/Musify.StreamingGateway
Updates every reference to the old paths: ProjectReference entries in
Musify.Api.csproj and Musify.Worker.csproj, the three Dockerfiles,
deploy/scripts/migrate.ps1|sh, deploy/zitadel/provision.ps1,
deploy/up.ps1, deploy/README.md and docs/development.md. Also fixes a
stale Dockerfile comment pointing at a compose file that no longer
exists.
Verified with `dotnet build Musify.slnx` against the new layout.
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- Remove the superseded standalone seaweedfs compose; point docs/development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.
