How to debug config

Feels like I’m in the home stretch. For my test today I got the branch filter working. Then I updated the filter to be tags. I pushed a tag of 1.2.3.4, and every push on the branch after that causes the build to run. I’m hoping to be able to run the build only the first time a specific tag is pushed.

Any ideas on how I should tweak my config file to make sure that happens?

Thanks again in advance.

Here’s what the server sees my workspace definition in my configuration file as …

workflows:
  version: 2
  wfBuild:
    jobs:
    - build:
        filters:
          tags:
            only:
            - /^\d+\.\d+\.\d+\.\d+/

Here’s the configuration file:
