When deleting a release tag, this is what happens:
- Tags::DestroyService calls repository.rm_tag and calls project hooks and executes events. Call to rm_tag invokes Gitaly UserDeleteTagRequest
- Gitaly posts back to /internal/post_receive API which invokes PostReceive worker
- PostReceive worker invokes TagHooksService which calls the same hooks/services again
